SOS is a key activator of the small GTPase Ras. In cells, SOS-Ras signaling is thought to be initiated predominantly by membrane recruitment of SOS via the adaptor Grb2 and balanced by rapidly reversible Grb2-SOS binding kinetics. However, SOS has multiple protein and lipid interactions that provide linkage to the membrane. In reconstituted-membrane experiments, these Grb2-independent interactions were sufficient to retain human SOS on the membrane for many minutes, during which a single SOS molecule could processively activate thousands of Ras molecules. These observations raised questions concerning how receptors maintain control of SOS in cells and how membrane-recruited SOS is ultimately released. We addressed these questions in quantitative assays of reconstituted SOS-deficient chicken B-cell signaling systems combined with single-molecule measurements in supported membranes. These studies revealed an essentially one-way trafficking process in which membrane-recruited SOS remains trapped on the membrane and continuously activates Ras until being actively removed via endocytosis.

Disturbed vesicular trafficking of membrane proteins in prion disease.

Uchiyama, Keiji; Miyata, Hironori; Sakaguchi, Suehiro

2013-01-01

The pathogenic mechanism of prion diseases remains unknown. We recently reported that prion infection disturbs post-Golgi trafficking of certain types of membrane proteins to the cell surface, resulting in reduced surface expression of membrane proteins and abrogating the signal from the proteins. The surface expression of the membrane proteins was reduced in the brains of mice inoculated with prions, well before abnormal symptoms became evident. Prions or pathogenic prion proteins were mainly detected in endosomal compartments, being particularly abundant in recycling endosomes. Some newly synthesized membrane proteins are delivered to the surface from the Golgi apparatus through recycling endosomes, and some endocytosed membrane proteins are delivered back to the surface through recycling endosomes. These results suggest that prions might cause neuronal dysfunctions and cell loss by disturbing post-Golgi trafficking of membrane proteins via accumulation in recycling endosomes. Interestingly, it was recently shown that delivery of a calcium channel protein to the cell surface was impaired and its function was abrogated in a mouse model of hereditary prion disease. Taken together, these results suggest that impaired delivery of membrane proteins to the cell surface is a common pathogenic event in acquired and hereditary prion diseases.

Human trafficking and the dental professional.

O'Callaghan, Michael G

2012-05-01

"Human trafficking" is a term for a modern form of slavery. It is a criminal human rights violation and a significant health issue. Dental professionals can assist in recognizing victims of trafficking. The author conducted a PubMed search of the English-language literature through May 2011, which yielded no articles meeting the search criteria "dentistry" and "human trafficking prostitution." Given these results, the author reviewed articles published in medical journals, reports from both governmental and nongovernmental agencies and lay literature. The author examines the present state of human trafficking and provides information--including specific questions to ask--to help dentists identify victims. In addition, the author suggests means of notifying authorities and assisting trafficking victims. He also examines the health care needs of these patients. Human trafficking is a global problem, with thousands of victims in the United States, including many women and children. Dentists have a responsibility to act for the benefit of others, which includes detecting signs of abuse and neglect. Dental professionals are on the front lines with respect to encountering and identifying potential victims who seek dental treatment. Dentists can combat human trafficking by becoming informed and by maintaining vigilance in their practices.

Objectives (1) To estimate the proportion of National Health Service (NHS) professionals who have come into contact with trafficked people and (2) to measure NHS professionals’ knowledge and confidence to respond to human trafficking. Design A cross-sectional survey. Setting Face-to-face mandatory child protection and/or vulnerable adults training sessions at 10 secondary healthcare provider organisations in England, and meetings of the UK College of Emergency Medicine. Participants 782/892 (84.4%) NHS professionals participated, including from emergency medicine, maternity, mental health, paediatrics and other clinical disciplines. Measures Self-completed questionnaire developed by an expert panel. Questionnaire asks about prior training and contact with potential victims of trafficking, perceived and actual human trafficking knowledge, confidence in responding to human trafficking, and interest in future human trafficking training. Results 13% participants reported previous contact with a patient they knew or suspected of having been trafficked; among maternity services professionals this was 20.4%. However, 86.8% (n=679) reported lacking knowledge of what questions to ask to identify potential victims and 78.3% (n=613) reported that they had insufficient training to assist trafficked people. 71% (n=556), 67.5% (n=528) and 53.4% (n=418) lacked confidence in making appropriate referrals for men, women and children, respectively, who had been trafficked. 95.3% (n=746) of respondents were unaware of the scale of human trafficking in the UK, and 76.5% (n=598) were unaware that calling the police could put patients in more danger. Psychometric analysis showed that subscales measuring perceived knowledge, actual knowledge and confidence to respond to human trafficking demonstrated good internal consistency (Cronbach's αs 0.93, 0.63 and 0.64, respectively) and internal correlations.

Scannell, Meredith; MacDonald, Andrea E; Berger, Amanda; Boyer, Nichole

Human trafficking is a human rights violation and a global health problem. Victims of human trafficking have medical and mental health sequelae requiring specific healthcare interventions. Healthcare professionals may be the initial contact that these victims make outside the world of trafficking. Healthcare professionals are key agents in the identification of human trafficking, which is essential in eliminating this public health problem. Unfortunately, healthcare professionals are not always able to detect signs of human trafficking. Failure to detect results in missed opportunities to assist victims. This is a case report of a victim of human trafficking who presented to an emergency department with medical and mental health issues. Despite numerous encounters with different healthcare professionals, signs and symptoms of human trafficking were not identified. Skilled assessment made by a forensic nurse alerted the healthcare team to clear features of human trafficking associated with this person. Through this case report we illustrate the key role the nurse played in identifying signs of human trafficking. Improvement of human trafficking educational programs is highlighted as a key adjunct to improving detection and facilitating the proper treatment of victims.

This paper investigates the impact of legalized prostitution on human trafficking inflows. According to economic theory, there are two opposing effects of unknown magnitude. The scale effect of legalized prostitution leads to an expansion of the prostitution market, increasing human trafficking, while the substitution effect reduces demand for trafficked women as legal prostitutes are favored over trafficked ones. Our empirical analysis for a cross-section of up to 150 countries shows that th...

2014-04-01

Historically, cellular trafficking of lipids has received much less attention than protein trafficking, mostly because its biological importance was underestimated, involved sorting and translocation mechanisms were not known, and analytical tools were limiting. This has changed during the last decade, and we discuss here some progress made in respect to mitochondria and the trafficking of phospholipids, in particular cardiolipin. Different membrane contact site or junction complexes and putative lipid transfer proteins for intra- and intermembrane lipid translocation have been described, involving mitochondrial inner and outer membrane, and the adjacent membranes of the endoplasmic reticulum. An image emerges how cardiolipin precursors, remodeling intermediates, mature cardiolipin and its oxidation products could migrate between membranes, and how this trafficking is involved in cardiolipin biosynthesis and cell signaling events. Particular emphasis in this review is given to mitochondrial nucleoside diphosphate kinase D and mitochondrial creatine kinases, which emerge to have roles in both, membrane junction formation and lipid transfer.

Role of Occupational Therapy in Combating Human Trafficking.

Science.gov (United States)

Gorman, Kathleen W; Hatkevich, Beth Ann

Human trafficking is a modern-day form of slavery that includes sex trafficking, labor trafficking, and trafficking of children. It is estimated that 35.8 million people are enslaved around the world. Because of the traumatic experiences that victims of human trafficking encounter, the needs of victims are extensive and require the services of several providers, including health care providers, for victims to transform into survivors and thrivers. Currently, the role of occupational therapy is minimal and unexplored. The profession of occupational therapy has the capacity of having a profound role in both providing client-centered care services to victims and survivors of human trafficking and partaking in preventive advocacy efforts to combat human trafficking. Further advocacy efforts are required to promote the profession of occupational therapy in combating human trafficking. Copyright © 2016 by the American Occupational Therapy Association, Inc.

South Africa – Safe Haven for Human Traffickers? Employing the Arsenal of Existing Law to Combat Human Trafficking

Directory of Open Access Journals (Sweden)

H Oosthuizen

2012-03-01

Full Text Available aving ratified the Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children, South Africa is obliged to adopt legislative measures that criminalise human trafficking and comply with other standards laid down in this international instrument. However, by mid-2011, South Africa had not enacted the required comprehensive counter-trafficking legislation. The question that now arises is if the absence of such anti-trafficking legislation poses an insurmountable obstacle to the prosecution of traffickers for trafficking-related activities. In asking this question the article examines the utilisation of existing crimes in order to prosecute and punish criminal activities committed during the human trafficking process. Firstly, a selection of existing common law and statutory crimes that may often be applicable to trafficking related activities is mapped out. Secondly, transitional trafficking provisions in the Children's Act 38 of 2005 and the Criminal Law (Sexual Offences and Related Matters Amendment Act 32 of 2007 are discussed. Finally, since the Prevention and Combating of Trafficking in Persons Bill B7 of 2010 will in all probability be enacted in the near future, the use of other criminal law provisions in human trafficking prosecutions, even after the passing of this bill into law, is reflected upon.

Optineurin: A Coordinator of Membrane-Associated Cargo Trafficking and Autophagy

Directory of Open Access Journals (Sweden)

Thomas A. Ryan

2018-05-01

Full Text Available Optineurin is a multifunctional adaptor protein intimately involved in various vesicular trafficking pathways. Through interactions with an array of proteins, such as myosin VI, huntingtin, Rab8, and Tank-binding kinase 1, as well as via its oligomerisation, optineurin has the ability to act as an adaptor, scaffold, or signal regulator to coordinate many cellular processes associated with the trafficking of membrane-delivered cargo. Due to its diverse interactions and its distinct functions, optineurin is an essential component in a number of homeostatic pathways, such as protein trafficking and organelle maintenance. Through the binding of polyubiquitinated cargoes via its ubiquitin-binding domain, optineurin also serves as a selective autophagic receptor for the removal of a wide range of substrates. Alternatively, it can act in an ubiquitin-independent manner to mediate the clearance of protein aggregates. Regarding its disease associations, mutations in the optineurin gene are associated with glaucoma and have more recently been found to correlate with Paget’s disease of bone and amyotrophic lateral sclerosis (ALS. Indeed, ALS-associated mutations in optineurin result in defects in neuronal vesicular localisation, autophagosome–lysosome fusion, and secretory pathway function. More recent molecular and functional analysis has shown that it also plays a role in mitophagy, thus linking it to a number of other neurodegenerative conditions, such as Parkinson’s. Here, we review the role of optineurin in intracellular membrane trafficking, with a focus on autophagy, and describe how upstream signalling cascades are critical to its regulation. Current data and contradicting reports would suggest that optineurin is an important and selective autophagy receptor under specific conditions, whereby interplay, synergy, and functional redundancy with other receptors occurs. We will also discuss how dysfunction in optineurin-mediated pathways may lead

2012-08-01

Human trafficking has only recently emerged at the forefront of policy reform, even in developed nations. Yet, heightened awareness of the issue has not translated into effective policy as the majority of nations have ineffective antitrafficking practices; many countries have failed to criminalize human trafficking, whereas others do not actively enforce statutes in place. By applying Black's theory of law, this study offers a preliminary understanding into the variation of global prosecutorial efforts in human trafficking and adequacy of antitrafficking law. To isolate this relationship, the effects of trafficking markets are controlled. As with prior research, the study finds limited support for the theory. The article concludes with a discussion on the implications of the quantity of antitrafficking law and morphology association for policy development.

Plasma membrane intrinsic proteins (PIPs) are plant aquaporins that facilitate the diffusion of water and small uncharged solutes through the cell membrane. Deciphering the network of interacting proteins that modulate PIP trafficking to and activity in the plasma membrane is essential to improve our knowledge about PIP regulation and function. This review highlights the most recent advances related to PIP subcellular routing and dynamic redistribution, identifies some key molecular interacting proteins, and indicates exciting directions for future research in this field. A better understanding of the mechanisms by which plants optimize water movement might help in identifying new molecular players of agronomical relevance involved in the control of cellular water uptake and drought tolerance.

A brain-enriched multi-domain scaffolding protein, neurobeachin has been identified as a candidate gene for autism patients. Mutations in the synaptic adhesion protein cell adhesion molecule 1 (CADM1) are also associated with autism spectrum disorder, a neurodevelopmental disorder of uncertain molecular origin. Potential roles of neurobeachin and CADM1 have been suggested to a function of vesicle transport in endosomal trafficking. It seems that protein kinase B (AKT) and cyclic adenosine monophosphate (cAMP)-dependent protein kinase A (PKA) have key roles in the neuron membrane trafficking involved in the pathogenesis of autism. Attention deficit hyperactivity disorder (ADHD) is documented to dopaminergic insufficiencies, which is attributed to synaptic dysfunction of dopamine transporter (DAT). AKT is also essential for the DAT cell-surface redistribution. In the present paper, we summarize and discuss the importance of several protein kinases that regulate the membrane trafficking involved in autism and ADHD, suggesting new targets for therapeutic intervention.

To examine the link between human trafficking of minors and childhood adversity. We compared the prevalence of adverse childhood experiences (ACEs) and cumulative childhood adversity (ACE score) among a sample of 913 juvenile justice-involved boys and girls in Florida for whom the Florida child abuse hotline accepted human trafficking abuse reports between 2009 and 2015 with those of a matched sample. ACE composite scores were higher and 6 ACEs indicative of child maltreatment were more prevalent among youths who had human trafficking abuse reports. Sexual abuse was the strongest predictor of human trafficking: the odds of human trafficking was 2.52 times greater for girls who experienced sexual abuse, and there was a 8.21 times greater risk for boys who had histories of sexual abuse. Maltreated youths are more susceptible to exploitation in human trafficking. Sexual abuse in connection with high ACE scores may serve as a key predictor of exploitation in human trafficking for both boys and girls.

Sinai Trafficking: Origin and Definition of a New Form of Human Trafficking

Directory of Open Access Journals (Sweden)

Mirjam van Reisen

2015-02-01

Full Text Available The phenomenon that is coined “Sinai Trafficking” started in 2009 in the Sinai desert. It involves the abduction, extortion, sale, torture, sexual violation and killing of men, women and children. Migrants, of whom the vast majority are from Eritrean descent, are abducted and brought to the Sinai desert, where they are sold and resold, extorted for very high ransoms collected by mobile phone, while being brutally and “functionally” tortured to support the extortion. Many of them die in Sinai. Over the last five years broadcasting stations, human rights organisations and academics have reported on the practices in the Sinai and some of these reports have resulted in some confusion on the modus operandi. Based on empirical research by the authors and the analysis of data gathered in more than 200 recorded interviews with Sinai hostages and survivors on the practices, this article provides a definition of Sinai Trafficking. It argues that the term Sinai Trafficking can be used to differentiate a particular new set of criminal practices that have first been reported in the Sinai Peninsula. The article further examines how the new phenomenon of Sinai Trafficking can be framed into the legal human trafficking definition. The interconnectedness of Sinai Trafficking with slavery, torture, ransom collection, extortion, sexual violence and other severe crimes is presented to substantiate the use of the trafficking framework. The plight of Sinai survivors in Israel and Egypt is explained to illustrate the cyclical process of the trafficking practices especially endured by Eritreans, introduced as the Human Trafficking Cycle. The article concludes by setting out areas for further research.

Phosphorylation-dependent trafficking of plasma membrane proteins in animal and plant cells.

Science.gov (United States)

Offringa, Remko; Huang, Fang

2013-09-01

In both unicellular and multicellular organisms, transmembrane (TM) proteins are sorted to and retained at specific membrane domains by endomembrane trafficking mechanisms that recognize sorting signals in the these proteins. The trafficking and distribution of plasma membrane (PM)-localized TM proteins (PM proteins), especially of those PM proteins that show an asymmetric distribution over the PM, has received much attention, as their proper PM localization is crucial for elementary signaling and transport processes, and defects in their localization often lead to severe disease symptoms or developmental defects. The subcellular localization of PM proteins is dynamically regulated by post-translational modifications, such as phosphorylation and ubiquitination. These modificaitons mostly occur on sorting signals that are located in the larger cytosolic domains of the cargo proteins. Here we review the effects of phosphorylation of PM proteins on their trafficking, and present the key examples from the animal field that have been subject to studies for already several decades, such as that of aquaporin 2 and the epidermal growth factor receptor. Our knowledge on cargo trafficking in plants is largely based on studies of the family of PIN FORMED (PIN) carriers that mediate the efflux of the plant hormone auxin. We will review what is known on the subcellular distribution and trafficking of PIN proteins, with a focus on how this is modulated by phosphorylation, and identify and discuss analogies and differences in trafficking with the well-studied animal examples. © 2013 Institute of Botany, Chinese Academy of Sciences.

HIV-1 matrix dependent membrane targeting is regulated by Gag mRNA trafficking.

Full Text Available Retroviral Gag polyproteins are necessary and sufficient for virus budding. Productive HIV-1 Gag assembly takes place at the plasma membrane. However, little is known about the mechanisms by which thousands of Gag molecules are targeted to the plasma membrane. Using a bimolecular fluorescence complementation (BiFC assay, we recently reported that the cellular sites and efficiency of HIV-1 Gag assembly depend on the precise pathway of Gag mRNA export from the nucleus, known to be mediated by Rev. Here we describe an assembly deficiency in human cells for HIV Gag whose expression depends on hepatitis B virus (HBV post-transcriptional regulatory element (PRE mediated-mRNA nuclear export. PRE-dependent HIV Gag expressed well in human cells, but assembled with slower kinetics, accumulated intracellularly, and failed to associate with a lipid raft compartment where the wild-type Rev-dependent HIV-1 Gag efficiently assembles. Surprisingly, assembly and budding of PRE-dependent HIV Gag in human cells could be rescued in trans by co-expression of Rev-dependent Gag that provides correct membrane targeting signals, or in cis by replacing HIV matrix (MA with other membrane targeting domains. Taken together, our results demonstrate deficient membrane targeting of PRE-dependent HIV-1 Gag and suggest that HIV MA function is regulated by the trafficking pathway of the encoding mRNA.

A Dual Role for the Nonreceptor Tyrosine Kinase Pyk2 during the Intracellular Trafficking of Human Papillomavirus 16.

Science.gov (United States)

Gottschalk, Elinor Y; Meneses, Patricio I

2015-09-01

The infectious process of human papillomaviruses (HPVs) has been studied considerably, and many cellular components required for viral entry and trafficking continue to be revealed. In this study, we investigated the role of the nonreceptor tyrosine kinase Pyk2 during HPV16 pseudovirion infection of human keratinocytes. We found that Pyk2 is necessary for infection and appears to be involved in the intracellular trafficking of the virus. Small interfering RNA-mediated reduction of Pyk2 resulted in a significant decrease in infection but did not prevent viral entry at the plasma membrane. Pyk2 depletion resulted in altered endolysosomal trafficking of HPV16 and accelerated unfolding of the viral capsid. Furthermore, we observed retention of the HPV16 pseudogenome in the trans-Golgi network (TGN) in Pyk2-depleted cells, suggesting that the kinase could be required for the viral DNA to exit the TGN. While Pyk2 has previously been shown to function during the entry of enveloped viruses at the plasma membrane, the kinase has not yet been implicated in the intracellular trafficking of a nonenveloped virus such as HPV. Additionally, these data enrich the current literature on Pyk2's function in human keratinocytes. In this study, we investigated the role of the nonreceptor tyrosine kinase Pyk2 during human papillomavirus (HPV) infection of human skin cells. Infections with high-risk types of HPV such as HPV16 are the leading cause of cervical cancer and a major cause of genital and oropharyngeal cancer. As a nonenveloped virus, HPV enters cells by interacting with cellular receptors and established cellular trafficking routes to ensure that the viral DNA reaches the nucleus for productive infection. This study identified Pyk2 as a cellular component required for the intracellular trafficking of HPV16 during infection. Understanding the infectious pathways of HPVs is critical for developing additional preventive therapies. Furthermore, this study advances our knowledge of

Redefining the essential trafficking pathway for outer membrane lipoproteins

The outer membrane (OM) of Gram-negative bacteria is a permeability barrier and an intrinsic antibiotic resistance factor. Lipoproteins are OM components that function in cell wall synthesis, diverse secretion systems, and antibiotic efflux pumps. Moreover, each of the essential OM machines that assemble the barrier requires one or more lipoproteins. This dependence is thought to explain the essentiality of the periplasmic chaperone LolA and its OM receptor LolB that traffic lipoproteins to the OM. However, we show that in strains lacking substrates that are toxic when mislocalized, both LolA and LolB can be completely bypassed by activating an envelope stress response without compromising trafficking of essential lipoproteins. We identify the Cpx stress response as a monitor of lipoprotein trafficking tasked with protecting the cell from mislocalized lipoproteins. Moreover, our findings reveal that an alternate trafficking pathway exists that can, under certain conditions, bypass the functions of LolA and LolB, implying that these proteins do not perform any truly essential mechanistic steps in lipoprotein trafficking. Instead, these proteins’ key function is to prevent lethal accumulation of mislocalized lipoproteins. PMID:28416660

Modeling for Determinants of Human Trafficking: An Empirical Analysis

Seo-Young Cho

2015-02-01

Full Text Available This study aims to identify robust push and pull factors of human trafficking. I test for the robustness of 70 push and 63 pull factors suggested in the literature. In doing so, I employ an extreme bound analysis, running more than two million regressions with all possible combinations of variables for up to 153 countries during the period of 1995–2010. My results show that crime prevalence robustly explains human trafficking both in destination and origin countries. Income level also has a robust impact, suggesting that the cause of human trafficking shares that of economic migration. Law enforcement matters more in origin countries than destination countries. Interestingly, a very low level of gender equality may have constraining effects on human trafficking outflow, possibly because gender discrimination limits female mobility that is necessary for the occurrence of human trafficking.

Human trafficking is a human rights violation prevalent globally. Current guidelines highlight healthcare professionals' key role in responding to human trafficking, emphasizing the importance of medical education in raising awareness of trafficking. To assess pre-clerkship medical students' awareness of human trafficking and attitudes towards learning about trafficking in the medical curriculum at Canada's largest medical school. An anonymous, classroom-based questionnaire was designed, piloted and administered to first- and second-year medical students at one large Canadian medical school with a diverse student population. The questionnaire sought demographic data and information on students' self-perceived awareness of human trafficking and interest in learning about trafficking and other community health issues. 262 medical students completed the questionnaire (70.0% response). Most participants reported that they were not knowledgeable (48.5%) or only somewhat knowledgeable (45.4%) about human trafficking. 88.9% of participants were not familiar with signs and symptoms of trafficked persons. While students' responses indicated that they prioritized other social issues, a majority of participants (76.0%) thought that trafficking was important to learn about in medical school, especially identifying trafficked persons and their health needs. These medical students of one Canadian medical school demonstrated limited familiarity with the issue of human trafficking but largely felt that they should be taught more about this issue during their medical education. This assessment of early medical students' awareness of human trafficking is relevant to medical educators and the organizations that could develop the required educational curricula and resources.

Niina Meriläinen

2015-01-01

Full Text Available The purpose of this study is to better understand how the complex problem of human trafficking is addressed in international debates. How the discussion about human trafficking develops and how it is debated ultimately influences how the decision-making process unfolds. In order to understand the formation of public policy and laws, therefore, it is important to study the debate that occurs prior to decision making. This analysis focuses on the narratives used by major, well-established human rights and political actors that argue for necessary actions to be undertaken—such as the formation of new policies and laws in the European Union—as an attempt to protect citizens of the EU and other regions in the world from becoming victims of trafficking networks. Our research examines how the topic of human trafficking is framed and how this framework is intertwined in the debate with other social problems. We focus on how human trafficking is discussed by two well-established human rights Non-Governmental Organizations (NGOs, Amnesty International (Amnesty and Human Rights Watch (HRW, in addition to the European Parliament (EP. The research questions for this study include: (1 In what context is human trafficking discussed by the three actors? (2 How do these actors frame the definition of human trafficking in their presentations? To answer these questions, we have conducted a systematic content analysis of documents that include official statements and research reports of the NGOs, as well as resolutions and recommendations of the EP. Altogether, 240 documents were analyzed in detail. These findings indicate that the two human rights organizations, Amnesty and Human Rights Watch, along with the European Parliament, all address human trafficking as an important social problem, albeit to varying degrees. Each actor has a different method of correlating human trafficking with many other social problems, thereby emphasizing different causes and

This study aimed to build the evidence base around human trafficking (HT) and health in the U.S. by employing a quantitative approach to exploring the notion that health care providers encounter this population. Furthermore, this study sought to describe the health care settings most frequented by victims of human trafficking. This was an anonymous, retrospective study of survivors of U.S.-based human trafficking. One hundred and seventy-three participants who endured U.S.-based human trafficking were surveyed. The majority (68%, n=117) of participants were seen by a health care provider while being trafficked. Respondents most frequently reported visiting emergency/urgent care practitioners (56%), followed by primary care providers, dentists, and obstetricians/gynecologists (OB/GYNs). While health care providers are serving this patient population, they do not consistently identify them as victims of human trafficking.

P-glycoprotein (Pgp; ABCB1/MDR1) is a major efflux transporter at the blood-brain barrier (BBB), restricting the penetration of various compounds. In other tissues, trafficking of Pgp from subcellular stores to the cell surface has been demonstrated and may constitute a rapid way of the cell to respond to toxic compounds by functional membrane insertion of the transporter. It is not known whether drug-induced Pgp trafficking also occurs in brain capillary endothelial cells that form the BBB. In this study, trafficking of Pgp was investigated in human brain capillary endothelial cells (hCMEC/D3) that were stably transfected with a doxycycline-inducible MDR1-EGFP fusion plasmid. In the presence of doxycycline, these cells exhibited a 15-fold increase in Pgp-EGFP fusion protein expression, which was associated with an increased efflux of the Pgp substrate rhodamine 123 (Rho123). The chemotherapeutic agent mitomycin C (MMC) was used to study drug-induced trafficking of Pgp. Confocal fluorescence microscopy of single hCMEC/D3-MDR1-EGFP cells revealed that Pgp redistribution from intracellular pools to the cell surface occurred within 2 h of MMC exposure. Pgp-EGFP exhibited a punctuate pattern at the cell surface compatible with concentrated regions of the fusion protein in membrane microdomains, i.e., lipid rafts, which was confirmed by Western blot analysis of biotinylated cell surface proteins in Lubrol-resistant membranes. MMC exposure also increased the functionality of Pgp as assessed in three functional assays with Pgp substrates (Rho123, eFluxx-ID Gold, calcein-AM). However, this increase occurred with some delay after the increased Pgp expression and coincided with the release of Pgp from the Lubrol-resistant membrane complexes. Disrupting rafts by depleting the membrane of cholesterol increased the functionality of Pgp. Our data present the first direct evidence of drug-induced Pgp trafficking at the human BBB and indicate that Pgp has to be released from lipid

Full Text Available Trafficking in human organs is a specific and complex criminal phenomenon that takes place in several phases, with the participation of a large number of actors, often covering several jurisdictions. To effectively countering are necessary conceptual and terminological demarcation of organ trafficking from other similar phenomena, fundamental scientifically research of its shape and dynamics, and the construction of an adequate legislative framework, both at the national and international level. This paper first analyses the conceptual - terminological framework in which research of organ trafficking is range, and then presents a review and analysis of the development of ethical and normative international standards aimed at prevention and suppression this phenomenon. In the end, we analysed the current solutions in the domestic legislation. Nowadays, there are two parallel legislative regime that regulate the matter of organ trafficking. The first legislative regime that organ trafficking treated exclusively as a modality of transnational crime of human trafficking, and a second, recent, that organ trafficking treats as forbidden (incriminating activity that violates a regulatory system of organ (tissue cells transplantation.

Hodge, David R

2014-04-01

Human trafficking is a pressing social justice concern. Social work is uniquely situated to address this problem. However, despite the profession's commitment to social justice, the scholarship to equip social workers to address this issue has been largely absent from professional discourse. To address this gap, this article helps social work practitioners to assist victims of human trafficking. After orienting readers to the scope and process of human trafficking, the topics of victim identification, exit from trafficking, and the restoration of psychological wellness are discussed. By equipping themselves in these three areas, practitioners can advance social justice on behalf of some of the most exploited people in the world.

Human trafficking is a major global public health concern. It is a grave crime that violates human rights. Contrary to healthcare providers' perceptions, victims of human trafficking come in contact with the healthcare system while being trafficked, with the emergency department being the most frequented setting for medical treatment. In this article, we explore the anatomy of human trafficking, including the scope of the problem, definitions, and types and elements of human trafficking. The roles of clinicians, particularly emergency department nurses and advanced practice nurses, in screening and identifying those at risk are examined. Clinical practice tools and guidelines that may be used by clinicians to guide the treatment of human trafficking victims are reviewed. Finally, current strategies and resources that address human trafficking are presented. For the purpose of this article, the terms "human trafficking" or "trafficking" will be used throughout.

Human pendrin (SLC26A4, PDS) is an integral membrane protein acting as an electroneutral anion exchanger. Loss of function mutations in pendrin protein cause Pendred syndrome, a disorder characterized by sensorineural deafness and a partial iodide organification defect that may lead to thyroid goiter. Additionally, pendrin up-regulation could play a role in the pathogenesis of several diseases including bronchial asthma and chronic obstructive pulmonary disease (COPD). Therefore, monitoring the plasma membrane abundance and trafficking of pendrin in the context of a living cell is crucially important. Trafficking of pendrin to the plasma membrane was monitored by fluorescence resonance energy transfer (FRET), a physical phenomenon occurring between two fluorophores (the FRET donor and acceptor) located in close spatial proximity. Because the efficiency of the energy transfer is inversely proportional to the sixth power of the distance between donor and acceptor, FRET is extremely sensitive to small changes in distance between the donor and acceptor and is therefore a powerful tool to determine protein-protein interactions. FRET studies revealed that forskolin-induced cAMP production is associated with a significant increase of pendrin expression at plasma membrane, which is paralleled by a decrease in intracellular pH. Pendrin transposition to the membrane is accompanied with a partial depolymerization of actin cytoskeleton via Rho-GTPase inhibition. Trafficking to the plasma membrane is critical in the regulation of pendrin activity. Therefore, reliable tools for monitoring and quantifying this phenomenon are highly desirable. © 2014 S.

Identification and Management of Human Trafficking Victims in the Emergency Department.

Science.gov (United States)

Hachey, Lisa M; Phillippi, Julia C

Health care practitioners serve an important role in identification and assistance of human trafficking victims. Advanced practice registered nurses, including certified nurse midwives, clinical nurse specialists, and nurse practitioners, are in a unique position to interact with persons trafficked and seen in the clinical setting, yet they require knowledge to identify the signs of human trafficking. Lack of training and education has been identified as a barrier for health care professionals to recognize human trafficking victims and implement needed health care services (; ). Barriers to identification and management include gap in knowledge about the process to screen for trafficking, to assist victims, and to make referrals. A patient-centered, trauma-informed approach can provide a safe environment to sensitively screen patients for human trafficking. Advanced practice registered nurses should be able to assess for trafficking indicators, collaborate with multidisciplinary service providers, and ensure understanding and availability of federal, state, and local resources to manage the care of victims of trafficking.

Human Trafficking and Commercialization of Surrogacy in India

Full Text Available The Supreme Court of India, In Baby Manji Yamada versus Union of India & Anr. [2008] INSC 1656, popularly known as Manji Case, declared that Commercial Surrogacy is legal in India. As we know that, India is a developing country and here, most of the peoples are very poor and illiterate. Recently, human trafficking was increase with an uncontrollable rate in the entire world. In addition, making Commercialization of Surrogacy legal had already give birth to a new form of trafficking. Where, illiterate women from poor section is trafficked to run the reproductive industry of the Surrogacy. As we know that the traffickers, they used to trafficked girls/women for prostitution but now after the legalization of Commercial Surrogacy, they will trafficked girl/women for the reproductive industry as a raw material. The Immoral Trafficking Prevention Act (ITPA, 1956 and Sections 366(A and 372 of the Indian Penal Code, 1860 are the existing laws of India, which deals with human trafficking. However, none of these provisions contains any solution, to deal with this new serious issue of trafficking of women/girls for the purpose of Commercial Surrogacy in reproductive industries. These existing laws as well as the pending draft bill of Assisted Reproductive Technologies (ART Regulation Bill, 2010 needs an amendment to check this crime against women once again to protect the rights and health of the women.

Human trafficking, also called modern slavery, happens worldwide--and the United States is no exception. Within our borders, thousands of foreign nationals and U.S. citizens, many of them children, are forced or coerced into sex work or various forms of labor every year. Nurses and other health care providers who encounter victims of trafficking often don't realize it, and opportunities to intervene are lost. Although no one sign can demonstrate with certainty when someone is being trafficked, there are several indicators that clinicians should know. This article provides an overview of human trafficking, describes how to recognize signs that a person is being trafficked and how to safely intervene, and offers an extensive resource list.

Trafficking of plant plasma membrane aquaporins: multiple regulation levels and complex sorting signals.

Science.gov (United States)

Chevalier, Adrien S; Chaumont, François

2015-05-01

Aquaporins are small channel proteins which facilitate the diffusion of water and small neutral molecules across biological membranes. Compared with animals, plant genomes encode numerous aquaporins, which display a large variety of subcellular localization patterns. More specifically, plant aquaporins of the plasma membrane intrinsic protein (PIP) subfamily were first described as plasma membrane (PM)-resident proteins, but recent research has demonstrated that the trafficking and subcellular localization of these proteins are complex and highly regulated. In the past few years, PIPs emerged as new model proteins to study subcellular sorting and membrane dynamics in plant cells. At least two distinct sorting motifs (one cytosolic, the other buried in the membrane) are required to direct PIPs to the PM. Hetero-oligomerization and interaction with SNAREs (soluble N-ethylmaleimide-sensitive factor protein attachment protein receptors) also influence the subcellular trafficking of PIPs. In addition to these constitutive processes, both the progression of PIPs through the secretory pathway and their dynamics at the PM are responsive to changing environmental conditions. © The Author 2014.

Laura-Cristiana SPĂTARU-NEGURĂ

2017-05-01

Full Text Available After last year’s analysis regarding the European Union’s commitment to fight against the human beings trafficking, we have considered to further explore the human beings trafficking approach in the European Court of Human Rights case-law, the most developped regional jurisdiction on human rights. Surprisingly, the European Convention for the Protection of Human Rights and Fundamental Freedoms does not make an express reference to the human beings trafficking. However, we have to bear in mind that the Convention is a living instrument, its interpretation being made in the light of the present-day conditions. Thus, taking into consideration the global threat of this phenomenon, it is more obvious than ever that the Convention could not neglect this issue.

Child human trafficking victims: challenges for the child welfare system.

2010-08-01

Since the passing of the Victims of Trafficking and Violence Protection Act in 2000 and its reauthorization by President George Bush in 2008, federal, state and community efforts in identifying and providing services for victims of human trafficking have significantly improved. However, most of the research and resources for trafficking victims have been directed towards adults rather than children. Researchers agree that there is a growing number of sexually exploited and trafficked children in the United States yet few programs emphasize the unique experiences and special needs of this population. This article examines commercial sexual exploitation of children; differentiates the needs and problems between child prostitution and victims of human trafficking; reviews and critiques current treatment practices; and summarizes challenges and successes in working with child victims of human trafficking, offering practice and policy recommendations.

2015-02-01

Full Text Available Since the beginning of research on human trafficking, there has been attention paid to the challenges surrounding the illicit economy. In creating new strategies and initiatives on combatting human trafficking, there needs to be more discussion surrounding the legitimate economy and how the business sector can make an impact in the fight against trafficking. Currently, there is a growing movement of businesses that are looking to address human trafficking through training, education, and leadership initiatives; codes of conduct; supply chain management; and financial analysis. This paper will examine the latest in these strategies and approaches by businesses in the global war against human trafficking, in addition to a discussion of a new initiative engaging the private sector co-led by Dr. Louise Shelley and Christina Bain through the World Economic Forum’s Global Agenda Council Network.

Cunningham, Katherine C; Cromer, Lisa DeMarni

2016-01-01

Human trafficking is believed to oppress millions of people worldwide. Despite increased media attention and public awareness campaigns in recent years, no empirical research has examined public attitudes about human trafficking. The present study examined gender, sexual trauma history, and attitudes about human trafficking as they related to belief of a sex-trafficking scenario and willingness to blame the victim for the situation. Undergraduate students (N = 409) at a large private university in the Northeastern United States completed measures in which they responded to a vignette portraying sex trafficking in the United States. Participants also reported their personal trauma history and completed a Human Trafficking Myths Scale. Results indicated that gender and human trafficking myth acceptance, but not sexual trauma history, were significantly related to participants' belief of the sex-trafficking scenario and their perception of the victim's responsibility. Potential implications and directions for future research are discussed. © The Author(s) 2014.

Trafficking of children for labor and sexual exploitation violates basic human rights and constitutes a major global public health problem. Pediatricians and other health care professionals may encounter victims who present with infections, injuries, posttraumatic stress disorder, suicidality, or a variety of other physical or behavioral health conditions. Preventing child trafficking, recognizing victimization, and intervening appropriately require a public health approach that incorporates rigorous research on the risk factors, health impact, and effective treatment options for child exploitation as well as implementation and evaluation of primary prevention programs. Health care professionals need training to recognize possible signs of exploitation and to intervene appropriately. They need to adopt a multidisciplinary, outward-focused approach to service provision, working with nonmedical professionals in the community to assist victims. Pediatricians also need to advocate for legislation and policies that promote child rights and victim services as well as those that address the social determinants of health, which influence the vulnerability to human trafficking. This policy statement outlines major issues regarding public policy, medical education, research, and collaboration in the area of child labor and sex trafficking and provides recommendations for future work.

Trafficking in human beings is a growing phenomenon with an expanding body of literature. However, a gap is evident in this body of literature: original research focusing on specific incidents of human trafficking. At this time, the human trafficking literature is permeated with discussions of the sex trade, sexual exploitation, organized crime, global socioeconomic problems and human rights. While these issues are all pertinent to the human trafficking debate, the literature requires maturat...

Entrepreneurship and Innovation in the Fight Against Human Trafficking

Christina Bain

2017-06-01

Full Text Available There has been much discussed and written on the benefits of entrepreneurship education, as well as the importance of early access to this type of learning. But how can entrepreneurship education train and inspire the next generation of anti-trafficking leaders? How can entrepreneurship also be a driver for prevention and a source of economic stability for those at-risk and survivors of human trafficking? At present, there are entrepreneurs and entrepreneurs-in-training at multiple age levels coming from a variety of backgrounds, incomes, and circumstances who will develop groundbreaking strategies and solutions in the fight against trafficking. These current and future entrepreneurs can also provide fresh perspectives to those in government and business while building more effective tri-sector coalitions and partnerships that address human trafficking. This article explores how and why entrepreneurship can be a key vehicle for social change and innovations in combating human trafficking, along with providing a multi-ingredient recipe of prosperity for those most vulnerable.

Human trafficking is a form of modern-day slavery that is rapidly expanding in the United States and throughout the world. It is a crime under both the United States and international law. The child and adult victims of human trafficking are denied their basic human rights and subjected to unspeakable physical and emotional harm. Traffickers exert complete control over their victims and are proficient at hiding their condition from authorities. Healthcare practitioners may be the only professionals who come into contact with victims if they present for medical care. This article will describe human trafficking and its potential victims, as well as guide medical management and access to services that will ensure their safety and restore their freedom.

A FRET-Based Approach for Quantitative Evaluation of Forskolin-Induced Pendrin Trafficking at the Plasma Membrane in Bronchial NCI H292 Cells

Directory of Open Access Journals (Sweden)

Grazia Tamma

2013-12-01

Full Text Available Background: Human pendrin (SLC26A4, PDS is an integral membrane protein acting as an electroneutral anion exchanger. Loss of function mutations in pendrin protein cause Pendred syndrome, a disorder characterized by sensorineural deafness and a partial iodide organification defect that may lead to thyroid goiter. Additionally, pendrin up-regulation could play a role in the pathogenesis of several diseases including bronchial asthma and chronic obstructive pulmonary disease (COPD. Therefore, monitoring the plasma membrane abundance and trafficking of pendrin in the context of a living cell is crucially important. Methods: Trafficking of pendrin to the plasma membrane was monitored by fluorescence resonance energy transfer (FRET, a physical phenomenon occurring between two fluorophores (the FRET donor and acceptor located in close spatial proximity. Because the efficiency of the energy transfer is inversely proportional to the sixth power of the distance between donor and acceptor, FRET is extremely sensitive to small changes in distance between the donor and acceptor and is therefore a powerful tool to determine protein-protein interactions. Results: FRET studies revealed that forskolin-induced cAMP production is associated with a significant increase of pendrin expression at plasma membrane, which is paralleled by a decrease in intracellular pH. Pendrin transposition to the membrane is accompanied with a partial depolymerization of actin cytoskeleton via Rho-GTPase inhibition. Conclusion: Trafficking to the plasma membrane is critical in the regulation of pendrin activity. Therefore, reliable tools for monitoring and quantifying this phenomenon are highly desirable.

Trafficking in human beings is a modern form of slavery and is a well-known phenomenon throughout the European Union and beyond. After drug dealing and the weapons industry, human trafficking is the second largest criminal activity in the world today and it is a growing crime. The aim of governmental and non-governmental agencies, which are either directly or indirectly involved in combating trafficking in human beings, is the identification and referral of victims of trafficking and also to encourage self-referrals. Identification is the most important step to provide protection and assistance to victims of trafficking. Victims often have a variety of physical and mental health needs, including psychological trauma, injuries from violence, head and neck trauma, sexually transmitted infections and other gynaecological problems, dental/oral problems and have poor nutrition. The author's experience in the field of community dentistry in presented within. Volunteer dental services are offered to non-European Union patients held in a centre for asylum seekers in Bari (Italy). Dental professionals can, in fact, contribute to the identification, assistance and protection of trafficked persons, as well as offering forensic services to assist the police investigation in order to identify crimes and find the criminal organizations behind them. As for domestic violence and child abuse cases, there are ethical concerns involved in the identification and protection of the trafficked persons, as well as the need for interdisciplinary work and awareness. Adequate training in behavioural science and intercultural learning is paramount in order to avoid misunderstandings and increase sensitivity.

Most of the membrane trafficking phenomena including those involving the interactions between endosomes and lysosomes are regulated by changes in intracellular Ca 2+ (Ca i ). These processes are disturbed in some types of mucolipidoses and other lysosomal storage disorders, such as mucolipidosis IV (MLIV), a neurological disorder that usually presents during the first year of life with blindness, cognitive impairment, and psychomotor delays. It is caused by mutations in MCOLN1, the gene encoding mucolipin-1 (MLN1), which we have recently established to represent a Ca 2+ -permeable cation channel that is transiently modulated by changes in Ca i . The cells of MLIV patients contain enlarged lysosomes that are likely associated with abnormal sorting and trafficking of these and related organelles. We studied fibroblasts from MLIV patients and found disturbed Ca 2+ signaling and large acidic organelles such as late endosomes and lysosomes (LEL) with altered cellular localization in these cells. The fusion between LEL vesicles in these cells was defective. This is a Ca 2+ -dependent process related to signaling pathways involved in regulation of Ca 2+ homeostasis and trafficking. The MLN1 channels could play a key role in Ca 2+ release from LEL vesicles, which triggers the fusion and trafficking of these organelles. The characterization of this MLN1-mediated Ca 2+ -dependent process should provide new insights into the pathophysiological mechanisms that lead to the development of MLIV and other mucolipidoses associated with similar disturbances in membrane trafficking

The concept of exploitation in international human trafficking law

Human trafficking is commonly known as a criminal practice that takes place in the framework of sex trade: women and children are trafficked within a state, or from one state to another, for the purpose of sexual exploitation. Similarly, the early 20th century international conventions aimed to tackle ‘white slave traffic’, trafficking of women and children for sexual exploitation. However, it is misleading to see trafficking only within this context. People are trafficked so that they can be...

Mandatory Reporting of Human Trafficking: Potential Benefits and Risks of Harm.

English, Abigail

2017-01-01

Human trafficking, including both sex and labor trafficking, has profound consequences for the safety, health, and well-being of victims and survivors. Efforts to address human trafficking through prevention, protection, and prosecution are growing but remain insufficient. Mandatory reporting has the potential to bring victims and survivors to the attention of social service and law enforcement agencies but may discourage trafficked persons from seeking help, thereby limiting the ability of health care professionals to establish trust and provide needed care. States' experience in implementing child abuse laws can be useful in assessing the potential risks and benefits of mandatory reporting of human trafficking. © 2017 American Medical Association.

Socio-Economic Inequality, Human Trafficking, and the Global Slave Trade

Directory of Open Access Journals (Sweden)

John R. Barner

2014-04-01

Full Text Available The purpose of this paper is to discuss human trafficking within the broader framework of socio-economic inequality. The presence of socio-economic inequality in the world creates a system where those in power very easily dominate and take advantage of those people without power. One of the most serious contemporary effects of inequalities between and within nations is the phenomenon of global sex trade or human trafficking for the purposes of sex. Deriving from unequal power relations, human trafficking is a serious global crime that involves the exploitation of many, but mostly females and children. This paper provides an extensive discussion of inequality and its links with human trafficking as contemporary slavery. In conclusion, the paper provides a list of selected intra-national and multi-national service organizations that are adopting strategies for combating trafficking through the reduction of social and economic inequality. Implications for social welfare advocates and international collaborative efforts are highlighted.

In an effort to combat human trafficking, the United States federal government and all fifty states passed new laws that criminalise human trafficking and support the identification and prosecution of human trafficking perpetrators. Despite the passage of these laws, only a small number of human trafficking cases have been prosecuted in the last fifteen years. Guided by the notion that prosecutors seek to avoid uncertainty when making decisions to pursue criminal prosecution, we explore how h...

Protein trafficking and maturation regulate intramembrane proteolysis.

Science.gov (United States)

Morohashi, Yuichi; Tomita, Taisuke

2013-12-01

Intramembrane-cleaving proteases (I-CLiPs) are membrane embedded proteolytic enzymes. All substrates identified so far are also membrane proteins, involving a number of critical cellular signaling as well as human diseases. After synthesis and assembly at the endoplasmic reticulum, membrane proteins are exported to the Golgi apparatus and transported to their sites of action. A number of studies have revealed the importance of the intracellular membrane trafficking in i-CLiP-mediated intramembrane proteolysis, not only for limiting the unnecessary encounter between i-CLiPs and their substrate but also for their cleavage site preference. In this review, we will discuss recent advances in our understanding of how each i-CLiP proteolysis is regulated by intracellular vesicle trafficking.

Etiological Aspects of Human Trafficking in Kosovo

Emine Abdyli

2017-08-01

Full Text Available Human trafficking is considered one of the most serious criminal offences, which is presented as a contemporary form of slavery and which implies the most brutal violation of basic human rights, which are guaranteed by international and law and national law. The phenomenon of human trafficking is present in many countries in transition (such as Kosovo, namely in those countries which were affected by internal political, economic, social, educational, etc. changes, and in such situations the perpetrators of this offense are in a very favorable position to victimize society. Therefore, this paper will focus on external criminogenic factors that influence the growth of this negative phenomenon, including the difficult economic situation, poverty and unemployment, poor housing, migration of people, domestic violence, the impact of mass media in society, lack of border control and insufficient effectiveness of institutions to deal with law enforcement. The paper is based on literature review, statistical data and interviews by treating the subject theoretically, legislatively and practically. To successfully fight against human trafficking, relevant authorities should more closely approach the etiological treatment of this negative phenomenon.

A model for assessing the risk of human trafficking on a local level

Science.gov (United States)

Colegrove, Amanda

Human trafficking is a human rights violation that is difficult to quantify. Models for estimating the number of victims of trafficking presented by previous researchers depend on inconsistent, poor quality data. As an intermediate step to help current efforts by nonprofits to combat human trafficking, this project presents a model that is not dependent on quantitative data specific to human trafficking, but rather profiles the risk of human trafficking at the local level through causative factors. Businesses, indicated by the literature, were weighted based on the presence of characteristics that increase the likelihood of trafficking in persons. The mean risk was calculated by census tract to reveal the multiplicity of risk levels in both rural and urban settings. Results indicate that labor trafficking may be a more diffuse problem in Missouri than sex trafficking. Additionally, spatial patterns of risk remained largely the same regardless of adjustments made to the model.

Decreasing Human Trafficking through Sex Work Decriminalization.

In order to decrease human trafficking, health care workers should support the full decriminalization of prostitution. Similar to trafficking in other forms of labor, preventing trafficking in the sex trade requires addressing the different forms of marginalization that create vulnerable communities. By removing punitive laws that prevent reporting of exploitation and abuse, decriminalization allows sex workers to work more safely, thereby reducing marginalization and vulnerability. Decriminalization can also help destigmatize sex work and help resist political, social, and cultural marginalization of sex workers. © 2017 American Medical Association. All Rights Reserved.

Prevention of Human Trafficking in Ethiopia: Assessing The Legal Framework

Zelalem Shiferaw Woldemichael

2017-12-01

Full Text Available Recent findings have indicated that both in-country trafficking (trafficking of individuals from rural areas to relatively affluent towns and cities and external trafficking (trafficking of individuals from a given country to foreign countries are prevalent in Ethiopia. In 2012, the government acceded to the Protocol to Suppress and Punish Trafficking in Persons Especially Women and Children supplementing the United Nations Convention against Transnational Organized Crime (The UN Trafficking Protocol, here after. With a view to giving effect to the requirements of this instrument, the government passed in to law Proclamation No. 909/2015 (The Prevention and Suppression of Trafficking in Persons and Smuggling of Migrants Proclamation, which is the most comprehensive of all laws adopted in Ethiopia to deal with human trafficking. Taking in to account the fact that human trafficking is exacerbated by the absence of regulatory framework on the employment of Ethiopian nationals in foreign countries, the govern-ment has also brought in to practice Proclamation No. 923/2016 (Ethiopia’s Overseas Employment Proclamation. This article has examined whether the above-mentioned laws of Ethiopia comply with international standards in dealing with prevention strategies.

Public Perceptions of Human Trafficking in Moldova

Directory of Open Access Journals (Sweden)

Jill Robinson

2011-11-01

Full Text Available Human trafficking is a widely studied phenomenon. Comparing public perceptions of trafficking to institutional (i.e. the academy, governmental and non-governmental organizations perceptions gives a richer understanding of the problem. The data for this study were collected in and around Chisinau, Moldova in the summer of 2004. Public discourse provides a more intimate "portraiture" of the issue, but the public also demonstrated a complex level of understanding of this social problem in this study. Its view is juxtaposed against an institutional view of human trafficking as explored through a literature review. Combining institutional and public perceptions and knowledge of a social problem is helpful in not only establishing a more thorough understanding of the social problem and guiding policy decisions, but in exploring the experiences victims may face at the community level.

Healthcare providers have the potential to play a crucial role in human trafficking prevention, identification, and intervention. However, trafficked patients are often unidentified due to lack of education and preparation available to healthcare professionals at all levels of training and practice. To increase victim identification in healthcare settings, providers need to be educated about the issue of trafficking and its clinical presentations in an interactive format that maximizes learning and ultimately patient-centered outcomes. In 2014, University of Louisville School of Medicine created a simulation-based medical education (SBME) curriculum to prepare students to recognize victims and intervene on their behalf. The authors share the factors that influenced the session's development and incorporation into an already full third year medical curriculum and outline the development process. The process included a needs assessment for the education intervention, development of objectives and corresponding assessment, implementation of the curriculum, and finally the next steps of the module as it develops further. Additional alternatives are provided for other medical educators seeking to implement similar modules at their home institution. It is our hope that the description of this process will help others to create similar interactive educational programs and ultimately help trafficking survivors receive the care they need.

Exosomes derived from human macrophages suppress endothelial cell migration by controlling integrin trafficking.

Science.gov (United States)

Lee, Hee Doo; Kim, Yeon Hyang; Kim, Doo-Sik

2014-04-01

Integrin trafficking, including internalization, recycling, and lysosomal degradation, is crucial for the regulation of cellular functions. Exosomes, nano-sized extracellular vesicles, are believed to play important roles in intercellular communications. This study demonstrates that exosomes released from human macrophages negatively regulate endothelial cell migration through control of integrin trafficking. Macrophage-derived exosomes promote internalization of integrin β1 in primary HUVECs. The internalized integrin β1 persistently accumulates in the perinuclear region and is not recycled back to the plasma membrane. Experimental results indicate that macrophage-derived exosomes stimulate trafficking of internalized integrin β1 to lysosomal compartments with a corresponding decrease in the integrin destined for recycling endosomes, resulting in proteolytic degradation of the integrin. Moreover, ubiquitination of HUVEC integrin β1 is enhanced by the exosomes, and exosome-mediated integrin degradation is blocked by bafilomycin A, a lysosomal degradation inhibitor. Macrophage-derived exosomes were also shown to effectively suppress collagen-induced activation of the mitogen-activated protein kinase/extracellular signal-regulated kinase signaling pathway and HUVEC migration, which are both dependent on integrin β1. These observations provide new insight into the functional significance of exosomes in the regulation of integrin trafficking. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Given the significant global burden of human trafficking, the ability of clinicians to identify and provide treatment for trafficked persons is critical. Particularly in conflict settings, health care facilities often serve as the first and sometimes only point of contact for trafficked persons. As such, medical practitioners have a unique opportunity and an ethical imperative to intervene, even in nonclinical roles. With proper training, medical practitioners can assist trafficked persons by documenting human trafficking cases, thereby placing pressure on key stakeholders to enforce legal protections, and by providing adequate services to those trafficked. © 2017 American Medical Association.

Human trafficking is an increasingly well-recognized human rights violation that is estimated to involve more than 2 million victims worldwide each year. The health consequences of this issue bring victims into contact with health systems and healthcare providers, thus providing the potential for identification and intervention. A robust healthcare response, however, requires a healthcare workforce that is aware of the health impact of this issue; educated about how to identify and treat affected individuals in a compassionate, culturally aware, and trauma-informed manner; and trained about how to collaborate efficiently with law enforcement, case management, and advocacy partners. This article describes existing educational offerings about human trafficking designed for a healthcare audience and makes recommendations for further curriculum development. A keyword search and structured analysis of peer-reviewed and gray literature, conducted in 2011 and 2012, yielded 27 items that provide basic guidance to health professionals on human trafficking. The 27 resources differed substantially in format, length, scope, and intended audience. Topic areas covered by these resources included trafficking definitions and scope, health consequences, victim identification, appropriate treatment, referral to services, legal issues, and security. None of the educational resources has been rigorously evaluated. There is a clear need to develop, implement, and evaluate high-quality education and training programs that focus on human trafficking for healthcare providers.

Human Trafficking and the Rome Statute of the International Criminal Court

Directory of Open Access Journals (Sweden)

CLARE FRANCES MORAN

2014-12-01

Full Text Available The case for extending the reach of the Rome Statute to the crime of human trafficking has not yet been made in detail. The brutality which occurs when human beings are trafficked by criminal gangs is of an equally egregious nature as the other crimes covered by the Rome Statute and yet it does not fall within the remit of the International Criminal Court. Such trafficking may also fall outwith the definition of slavery as a crime against humanity, particularly given the State policy threshold set by the Statute. This paper seeks to explore the viability of the inclusion of human trafficking as a discrete international crime within the Rome Statute as a response to this loophole.

National Human Trafficking Initiatives: Dimensions of Policy Diffusion.

Science.gov (United States)

Yoo, Eun-Hye; Boyle, Elizabeth Heger

2015-01-01

The implementation of criminal law involves formal law enforcement, education and public outreach aimed at preventing criminal activity, and providing services for victims. Historically, quantitative research on global trends has tended to focus on a single policy dimension, potentially masking the unique factors that affect the diffusion of each policy dimension independently. Using an ordered-probit model to analyze new human trafficking policy data on national prosecution, prevention, and victim-protection efforts, we find that global ties and domestic interest groups matter more in areas where international law is less defined. While prosecution, officially mandated by the Trafficking Protocol, was relatively impervious to global ties and domestic interest groups, both trafficking prevention and victim protection were associated with these factors. Our findings also suggest that fear of repercussions is not a major driver of state actions to combat trafficking-neither ratification of the Trafficking Protocol nor levels of United States aid were associated with greater implementation of anti-trafficking measures.

Arabidopsis SNAREs SYP61 and SYP121 coordinate the trafficking of plasma membrane aquaporin PIP2;7 to modulate the cell membrane water permeability.

Plant plasma membrane intrinsic proteins (PIPs) are aquaporins that facilitate the passive movement of water and small neutral solutes through biological membranes. Here, we report that post-Golgi trafficking of PIP2;7 in Arabidopsis thaliana involves specific interactions with two syntaxin proteins, namely, the Qc-SNARE SYP61 and the Qa-SNARE SYP121, that the proper delivery of PIP2;7 to the plasma membrane depends on the activity of the two SNAREs, and that the SNAREs colocalize and physically interact. These findings are indicative of an important role for SYP61 and SYP121, possibly forming a SNARE complex. Our data support a model in which direct interactions between specific SNARE proteins and PIP aquaporins modulate their post-Golgi trafficking and thus contribute to the fine-tuning of the water permeability of the plasma membrane. © 2014 American Society of Plant Biologists.

Quite aside from its immense importance as a human pathogen, studies in recent years have brought to light the fact that the malaria parasite Plasmodium falciparum is an interesting eukaryotic model system to study protein trafficking. Studying parasite cell biology often reveals an overrepresentation of atypical cell biological features, possibly driven by the parasites' need to survive in an unusual biological niche. Malaria parasites possess uncommon cellular compartments to which protein traffic must be directed, including secretory organelles such as rhoptries and micronemes, a lysosome-like compartment referred to as the digestive vacuole and a complex (four membrane-bound) plastid, the apicoplast. In addition, the parasite must provide proteins to extracellular compartments and structures including the parasitophorous vacuole, the parasitophorous vacuolar membrane, the Maurer's clefts and both cytosol and plasma membrane of the host cell, the mature human red blood cell. Although some of these unusual destinations are possessed by other cell types, only Plasmodium parasites contain them all within one cell. Here we review what is known about protein and membrane transport in the P. falciparum-infected cell, highlighting novel features of these processes. A growing body of evidence suggests that this parasite is a real "box of tricks" with regards to protein traffic. Possibly, these tricks may be turned against the parasite by exploiting them as novel therapeutic targets. Copyright © 2012 Elsevier B.V. All rights reserved.

Plasma membrane protein trafficking in plant-microbe interactions: a plant cell point of view

Directory of Open Access Journals (Sweden)

Nathalie eLeborgne-Castel

2014-12-01

Full Text Available In order to ensure their physiological and cellular functions, plasma membrane (PM proteins must be properly conveyed from their site of synthesis, i.e. the endoplasmic reticulum, to their final destination, the PM, through the secretory pathway. PM protein homeostasis also relies on recycling and/or degradation, two processes that are initiated by endocytosis. Vesicular membrane trafficking events to and from the PM have been shown to be altered when plant cells are exposed to mutualistic or pathogenic microbes. In this review, we will describe the fine-tune regulation of such alterations, and their consequence in PM protein activity. We will consider the formation of intracellular perimicrobial compartments, the PM protein trafficking machinery of the host, and the delivery or retrieval of signaling and transport proteins such as pattern-recognition receptors, producers of reactive oxygen species, and sugar transporters.

Loss-of-function of the ciliopathy protein Cc2d2a disorganizes the vesicle fusion machinery at the periciliary membrane and indirectly affects Rab8-trafficking in zebrafish photoreceptors.

Ciliopathies are human disorders caused by dysfunction of primary cilia, ubiquitous organelles involved in transduction of environmental signals such as light sensation in photoreceptors. Concentration of signal detection proteins such as opsins in the ciliary membrane is achieved by RabGTPase-regulated polarized vesicle trafficking and by a selective barrier at the ciliary base, the transition zone (TZ). Dysfunction of the TZ protein CC2D2A causes Joubert/Meckel syndromes in humans and loss of ciliary protein localization in animal models, including opsins in retinal photoreceptors. The link between the TZ and upstream vesicle trafficking has been little explored to date. Moreover, the role of the small GTPase Rab8 in opsin-carrier vesicle (OCV) trafficking has been recently questioned in a mouse model. Using correlative light and electron microscopy and live imaging in zebrafish photoreceptors, we provide the first live characterization of Rab8-mediated trafficking in photoreceptors in vivo. Our results support a possibly redundant role for both Rab8a/b paralogs in OCV trafficking, based on co-localization of Rab8 and opsins in vesicular structures, and joint movement of Rab8-tagged particles with opsin. We further investigate the role of the TZ protein Cc2d2a in Rab8-mediated trafficking using cc2d2a zebrafish mutants and identify a requirement for Cc2d2a in the latest step of OCV trafficking, namely vesicle fusion. Progressive accumulation of opsin-containing vesicles in the apical portion of photoreceptors lacking Cc2d2a is caused by disorganization of the vesicle fusion machinery at the periciliary membrane with mislocalization and loss of the t-SNAREs SNAP25 and Syntaxin3 and of the exocyst component Exoc4. We further observe secondary defects on upstream Rab8-trafficking with cytoplasmic accumulation of Rab8. Taken together, our results support participation of Rab8 in OCV trafficking and identify a novel role for the TZ protein Cc2d2a in fusion of incoming

2017-06-01

Full Text Available Migration, technology, law, and measurement are each among the most topical areas of enquiry in the global human trafficking field, with much work remaining to be done in these and other areas. Beneath these particular intersections lies a crucial truth—slavery is a global business that thrives on the callous exploitation of the labor activity of a vast and highly vulnerable subclass of people whose brutalization is tacitly accepted by every participant in the global economy, from corporations to consumers. I am deeply gratified to edit Social Inclusion’s second issue on human trafficking and modern slavery. The level of scholarly interest in these topics continues to grow, and in this issue the authors explore some of the most pressing manifestations of human trafficking around the world.

Pancreatic acinar cells have an expanded apical endosomal system, the physiological and pathophysiological significance of which is still emerging. Phosphatidylinositol-3,5-bisphosphate (PI(3,5)P 2 ) is an essential phospholipid generated by PIKfyve, which phosphorylates phosphatidylinositol-3-phosphate (PI(3)P). PI(3,5)P 2 is necessary for maturation of early endosomes (EE) to late endosomes (LE). Inhibition of EE to LE trafficking enhances anterograde endosomal trafficking and secretion at the plasma membrane by default through a recycling endosome (RE) intermediate. We assessed the effects of modulating PIKfyve activity on apical trafficking and pancreatitis responses in pancreatic acinar cells. Inhibition of EE to LE trafficking was achieved using pharmacological inhibitors of PIKfyve, expression of dominant negative PIKfyve K1877E, or constitutively active Rab5-GTP Q79L. Anterograde endosomal trafficking was manipulated by expression of constitutively active and dominant negative Rab11a mutants. The effects of these agents on secretion, endolysosomal exocytosis of lysosome associated membrane protein (LAMP1), and trypsinogen activation in response to high-dose CCK-8, bile acids and cigarette toxin was determined. PIKfyve inhibition increased basal and stimulated secretion. Adenoviral overexpression of PIKfyve decreased secretion leading to cellular death. Expression of Rab5-GTP Q79L or Rab11a-GTP Q70L enhanced secretion. Conversely, dominant-negative Rab11a-GDP S25N reduced secretion. High-dose CCK inhibited endolysosomal exocytosis that was reversed by PIKfyve inhibition. PIKfyve inhibition blocked intracellular trypsin accumulation and cellular damage responses to high CCK-8, tobacco toxin, and bile salts in both rodent and human acini. These data demonstrate that EE-LE trafficking acutely controls acinar secretion and the intracellular activation of zymogens leading to the pathogenicity of acute pancreatitis.

Human Trafficking and Sexual Servitude: Organised Crime’s Involvement in Australia

Directory of Open Access Journals (Sweden)

Mark Langhorn

2018-03-01

Full Text Available This study examined the context of organised crime groups that traffic in people for the Australian sex industry. It is a qualitative study of twenty-one cases of human trafficking. The study found that criminal networks preyed on vulnerable females from countries such as Thailand, South Korea, and China. Victims were deceptively recruited with the cost of their travel to Australia held against them as a highly inflated debt. As a result, they find themselves forced into sex work to repay the debt. This study examined the attributes of the organised crime syndicates involved in the people trafficking and discussed the context in which they operate in Australia. The study used the Sleipnir framework to analyse organised crime groups and it is recommended that the Sleipnir model is integrated into future law enforcement activities in respect of human trafficking. The introduction of a standardised data and statistical collection tool in respect of human trafficking would provide law enforcement and intelligence agencies with a conceptual framework and a greater comprehensive description of human trafficking.

Nguyen, Phuong T; Lamkin, Joanna; Coverdale, John H; Scott, Samuel; Li, Karen; Gordon, Mollie R

2018-06-01

Human trafficking is a serious and prevalent human rights violation that closely intersects with mental health. Limited empirical attention has been paid to the presentations and identification of trafficking victims in psychiatric settings. The primary goal of this paper is to describe the varied presentations of trafficking victims on an urban inpatient psychiatric unit. A literature review was conducted to identify relevant empirical articles to inform our examination of cases. Adult inpatient cases meeting criteria for known or possible human trafficking were systematically identified and illustrative cases were described. Six cases were identified including one male and five females. Two had been labor trafficked and four were suspected or confirmed to have been sex trafficked. The cases demonstrated a tremendous diversity of demographic and psychiatric identifying factors. These cases indicate the importance of routinely screening for trafficking victims in inpatient psychiatry settings. Identification of cases is a requisite step in providing informed and evidence-based treatments and enabling the secondary prevention of re-exploitation. Additional research is warranted given the limited current empirical research on this topic area.

Human Rights, Positive Obligations, and Measures to Prevent Human Trafficking in the UK

OpenAIRE

Turner, Ian David

2015-01-01

Article 4 of the European Convention on Human Rights is freedom from slavery. A key feature of this right is the obligation it imposes on states such as the UK to prevent violations of the freedom, such as the trafficking in human beings, by third parties. This piece finds that the UK’s response to its duties in preventing human trafficking is patchy but concludes that this will be much improved with its new Modern Slavery Bill 2014-15.

Human trafficking is a significant human rights problem that is often associated with psychological and physical violence. There is no demographic that is spared from human trafficking. Traffickers maintain control of victims through physical, sexual, and emotional violence and manipulation. Because victims of trafficking seek medical attention for the medical and psychological consequences of assault and neglected health conditions, emergency clinicians are in a unique position to recognize victims and intervene. Evaluation of possible trafficking victims is challenging because patients who have been exploited rarely self-identify. This article outlines the clinical approach to the identification and treatment of a potential victim of human trafficking in the emergency department. Emergency practitioners should maintain a high index of suspicion when evaluating patients who appear to be at risk for abuse and violence, and assess for specific indicators of trafficking. Potential victims should be evaluated with a multidisciplinary and patient-centered technique. Furthermore, emergency practitioners should be aware of national and local resources to guide the approach to helping identified victims. Having established protocols for victim identification, care, and referrals can greatly facilitate health care providers' assisting this population.

Children, youth, and adults of both genders are sex trafficked into and throughout the United States every day. Regrettably, little attention has been given to how human service providers might identify the sex-trafficking victims they are likely to encounter. To address this knowledge gap, the authors review 20 documents with the aim of detecting and synthesizing service identification recommendations in the scientific literature, government reports, and documents produced by organizations working with sex-trafficking victims. The review shows consensus regarding identification recommendations, including (a) trafficking indicators, (b) victim interaction strategies, (c) immediate response strategies, and (d) child-specific information. The review also shows consensus regarding screening questions that are important for service providers to use in identifying sex-trafficking victims. These questions relate to the victims' safety, employment, living environment, and travel and immigration status in addition to specific questions used with children and youth. The review results offer human service providers a preliminary set of screening strategies and questions that can be used to identify sex-trafficking victims in the context of human services. Building on the review findings, the authors offer policy and research recommendations.

Human trafficking: Commercial sexual exploitation and forced domestic labour in African literature

Full Text Available Just like social occurrences such as human sacrifice and slavery enhanced retardation of progress in Africa in the past, trafficking is another social occurrence addressed in contemporary African literature that impedes progress and tarnishes the image of the victims. Human trafficking is rampant in Africans and some part of the world in this 21st century. This paper examines how Akachi Adimora-Ezeigbo’s Trafficked (2008 and Chika Unigwe’s On Black Sisters′ Street (2009 highlight social occurrences and how they contribute to the spread of girl trafficking in Africa. It also explores how both men and women are partners in trafficking, forming trafficking networks that lure girls from Nigeria to Europe and make huge profits from their misery. These pimps use ‘juju magic’ and rituals as a threat to exert complete control over the girls and also to ensure their compliance. The trafficked girls share their life experiences by telling their tales of woes exposing the shame that accompanies the sex trade and the stigmatization they suffer in the society. Their experiences are presented by the authors to highlight the trafficked girls′ pains, misery and struggle for freedom in order to appeal to everybody in the society to fight against human trafficking. The paper also examines how these exploited and depressed trafficked girls that have lost their self-esteem can still live fulfilled lives if government agencies and nongovernmental organizations come to their rescue.

Preliminary perspectives on DNA collection in anti-human trafficking efforts.

Forensic DNA methodologies have potential applications in the investigation of human trafficking cases. DNA and relationship testing may be useful for confirmation of biological relationship claims in immigration, identification of trafficked individuals who are missing persons, and family reunification of displaced individuals after mass disasters and conflicts. As these applications rely on the collection of DNA from non-criminals and potentially vulnerable individuals, questions arise as to how to address the ethical challenges of collection, security, and privacy of collected samples and DNA profiles. We administered a survey targeted to victims' advocates to gain preliminary understanding of perspectives regarding human trafficking definitions, DNA and sex workers, and perceived trust of authorities potentially involved in DNA collection. We asked respondents to consider the use of DNA for investigating adoption fraud, sex trafficking, and post-conflict child soldier cases. We found some key differences in perspectives on defining what qualifies as "trafficking." When we varied terminology between "sex worker" and "sex trafficking victim" we detected differences in perception on which authorities can be trusted. Respondents were supportive of the hypothetical models proposed to collect DNA. Most were favorable of DNA specimens being controlled by an authority outside of law enforcement. Participants voiced concerns focused on privacy, misuse of DNA samples and data, unintentional harms, data security, and infrastructure. These preliminary data indicate that while there is perceived value in programs to use DNA for investigating cases of human trafficking, these programs may need to consider levels of trust in authorities as their logistics are developed and implemented.

Monitoring and Evaluation of Human Trafficking Partnerships in England and Wales

Directory of Open Access Journals (Sweden)

Ruth Van Dyke

2017-04-01

Full Text Available In the United Kingdom, human trafficking and, more recently, modern slavery has been pushed up the political and policy agenda. At the same time, partnership working has been promoted at international and national levels in order to encourage a more holistic response to trafficking. This article examines the nature of the evidence collected to monitor and evaluate the activities and outcomes of organisations involved in a number of human trafficking partnerships in England and Wales. Underpinning this analysis is the ‘4 Ps’ approach to tackling human trafficking: Prevention, Protection, Prosecution and Partnership. Based on interviews with a variety of actors working in different partner bodies, limitations of evidence in relation to both monitoring activities as well as evaluating outcomes emerged. These relate to inadequate data collection, lack of robust methods of data collection, untested assumptions, the complexity of gathering evidence which reflect human welfare oriented goals, and the sharing of evidence between partner organisations. A key finding is that current data and methods of data collection are inadequate for the purpose of measuring the effectiveness of anti-trafficking initiatives and partnerships. Another key finding is the way in which partnerships challenged received outcomes and expanded their focus beyond victims of trafficking or criminal justice goals. Finally, I explore whether criminal justice outcomes can be leveraged to foster deterrence, by interrogating what evidence might be needed.

The golgin GMAP-210 is required for efficient membrane trafficking in the early secretory pathway.

Roboti, Peristera; Sato, Keisuke; Lowe, Martin

2015-04-15

Golgins are coiled-coil proteins that participate in membrane-tethering events at the Golgi complex. Golgin-mediated tethering is thought to be important for vesicular trafficking and Golgi organization. However, the degree to which individual golgins contribute to these processes is poorly defined, and it has been proposed that golgins act in a largely redundant manner. Previous studies on the golgin GMAP-210 (also known as TRIP11), which is mutated in the rare skeletal disorder achondrogenesis type 1A, have yielded conflicting results regarding its involvement in trafficking. Here, we re-investigated the trafficking role of GMAP-210, and found that it is indeed required for efficient trafficking in the secretory pathway. GMAP-210 acts at both the endoplasmic reticulum (ER)-to-Golgi intermediate compartment (ERGIC) and Golgi complex during anterograde trafficking, and is also required for retrograde trafficking to the ER. Using co-depletion experiments, we also found that GMAP-210 acts in a partially redundant manner with the golgin GM130 to ensure efficient anterograde cargo delivery to the cis-Golgi. In summary, our results indicate a role for GMAP-210 in several trafficking steps at the ER-Golgi interface, some of which are partially redundant with another golgin, namely GM130 (also known as GOLGA2). © 2015.

Kidney anion exchanger 1 (kAE1) plays an important role in acid-base homeostasis by mediating chloride/bicarbornate (Cl-/HCO3-) exchange at the basolateral membrane of α-intercalated cells in the distal nephron. Impaired intracellular trafficking of kAE1 caused by mutations of SLC4A1 encoding kAE1 results in kidney disease - distal renal tubular acidosis (dRTA). However, it is not known how the intracellular sorting and trafficking of kAE1 from trans-Golgi network (TGN) to the basolateral membrane occurs. Here, we studied the role of basolateral-related sorting proteins, including the mu1 subunit of adaptor protein (AP) complexes, clathrin and protein kinase D, on kAE1 trafficking in polarized and non-polarized kidney cells. By using RNA interference, co-immunoprecipitation, yellow fluorescent protein-based protein fragment complementation assays and immunofluorescence staining, we demonstrated that AP-1 mu1A, AP-3 mu1, AP-4 mu1 and clathrin (but not AP-1 mu1B, PKD1 or PKD2) play crucial roles in intracellular sorting and trafficking of kAE1. We also demonstrated colocalization of kAE1 and basolateral-related sorting proteins in human kidney tissues by double immunofluorescence staining. These findings indicate that AP-1 mu1A, AP-3 mu1, AP-4 mu1 and clathrin are required for kAE1 sorting and trafficking from TGN to the basolateral membrane of acid-secreting α-intercalated cells. © 2014 John Wiley & Sons A/S.

2016-02-01

This report presents a comprehensive set of recommendations for protection of human beings who are trafficked for the purpose of organ removal or are targeted for such trafficking. Developed by an interdisciplinary group of international experts under the auspices of the project Trafficking in Human Beings for the Purpose of Organ Removal (also known as the HOTT project), these recommendations are grounded in the view that an individual who parts with an organ for money within an illegal scheme is ipso facto a victim and that the crime of trafficking in human beings for the purpose of organ removal (THBOR) intersects with the crime of trafficking in organs. Consequently, the protection of victims should be a priority for all actors involved in antitrafficking activities: those combating organ-related crimes, such as health organizations and survivor support services, and those combating trafficking in human beings, such as the criminal justice sectors. Taking into account the special characteristics of THBOR, the authors identify 5 key stakeholders in the protection of human beings trafficked for organ removal or targeted for such trafficking: states, law enforcement agencies and judiciary, nongovernmental organizations working in the areas of human rights and antitrafficking, transplant centers and health professionals involved in transplant medicine, and oversight bodies. For each stakeholder, the authors identify key areas of concern and concrete measures to identify and protect the victims of THBOR. The aim of the recommendations is to contribute to the development of a nonlegislative response to THBOR, to promote the exchange of knowledge and best practices in the area of victim protection, and to facilitate the development of a policy-driven action plan for the protection of THBOR victims in the European Union and worldwide.

Physician Encounters with Human Trafficking: Legal Consequences and Ethical Considerations.

Science.gov (United States)

Todres, Jonathan

2017-01-01

There is growing recognition and evidence that health care professionals regularly encounter-though they may not identify-victims of human trafficking in a variety of health care settings. Identifying and responding appropriately to trafficking victims or survivors requires not only training in trauma-informed care but also consideration of the legal and ethical issues that arise when serving this vulnerable population. This essay examines three areas of law that are relevant to this case scenario: criminal law, with a focus on conspiracy; service provider regulations, with a focus on mandatory reporting laws; and human rights law. In addition to imposing a legal mandate, the law can inform ethical considerations about how health care professionals should respond to human trafficking. © 2017 American Medical Association.

Hospitalization is one of the few circumstances in which the lives of trafficking victims intersect with the general population. Based on survivor testimonies, the majority of human trafficking victims may receive medical treatment in a hospital's emergency department while in captivity. With evidenced-based training, ED personnel have a better opportunity to screen persons who are being trafficked and intervene on their behalf. This project examined the efficacy of an innovative, evidence-based online training module (HTEmergency.com) created by the project team. Participants completed a pre-survey to determine learning needs and a post-survey to determine the effectiveness of the online education. The learning module contained a PowerPoint presentation, identification and treatment guidelines, and 2 realistic case studies. Data were collected among ED personnel in 2 suburban hospitals located near a northeast metropolitan city. Seventy-five employees participated in the survey and education. Staff completing the education included nurses, physicians, nurse practitioners/physician assistants, registration, and ED technicians. Results indicated that 89% of participants had not received previous human trafficking training. Less than half of the participants stated that they had a comprehensive understanding of human trafficking before the intervention, with an increase to 93% after education. The training module significantly increased confidence in identification (from an average confidence level of 4/10 to 7/10) and treatment (from an average confidence level of 4/10 to 8/10) of human trafficking victims within the emergency department; 96% found the educational module to be useful in their work setting. Participants reported that they are more confident in identifying a possible trafficking victim and are more likely to screen patients for human trafficking after participation in the online training module.

Captured ‘Realities’ of Human Trafficking: Analysis of photographs illustrating stories on trafficking into the sex industry in Serbian media

Directory of Open Access Journals (Sweden)

Elena Krsmanovic

2016-09-01

Full Text Available Past research has looked at how the media frames human trafficking, but has seldom included analysis of visual representations. To bridge this gap, this paper scrutinises stereotypical representations of persons trafficked into the sex industry in photographs published in Serbian online media from 2011 to 2014. To uncover characteristics of dominant tropes in this sample, a method of semiotic analysis is applied. The analysis argues that images are dominated by portrayals of trafficked persons that fit into one of two frames: powerless victim or unworthy prostitute. Male figures are rarely presented in these photographs, but when present, they are shown to hurt or control the women depicted alongside them. Chains, padlocks, barcodes, whip marks, and other symbols associated with slavery are present to a lesser extent. However, they testify to the tendency to link human trafficking to slavery and to use the moral potential of the anti-slavery rhetoric. Photographs are too easily seen as authentic, factual transcripts of reality. This paper suggests that these images tell us more about societal fear of insecurity, ideas about gender, erotic obsessions and morality than about human trafficking itself. It also argues that the meaning of trafficking is shaped by the deeply embedded codes of patriarchy and hidden misogyny present in Serbian society.

Vesicular membrane trafficking events to and from the PM have been shown to be altered when plant cells are exposed to mutualistic ...

Barcoding of GPCR trafficking and signaling through the various trafficking roadmaps by compartmentalized signaling networks.

Science.gov (United States)

Bahouth, Suleiman W; Nooh, Mohammed M

2017-08-01

Proper signaling by G protein coupled receptors (GPCR) is dependent on the specific repertoire of transducing, enzymatic and regulatory kinases and phosphatases that shape its signaling output. Activation and signaling of the GPCR through its cognate G protein is impacted by G protein-coupled receptor kinase (GRK)-imprinted "barcodes" that recruit β-arrestins to regulate subsequent desensitization, biased signaling and endocytosis of the GPCR. The outcome of agonist-internalized GPCR in endosomes is also regulated by sequence motifs or "barcodes" within the GPCR that mediate its recycling to the plasma membrane or retention and eventual degradation as well as its subsequent signaling in endosomes. Given the vast number of diverse sequences in GPCR, several trafficking mechanisms for endosomal GPCR have been described. The majority of recycling GPCR, are sorted out of endosomes in a "sequence-dependent pathway" anchored around a type-1 PDZ-binding module found in their C-tails. For a subset of these GPCR, a second "barcode" imprinted onto specific GPCR serine/threonine residues by compartmentalized kinase networks was required for their efficient recycling through the "sequence-dependent pathway". Mutating the serine/threonine residues involved, produced dramatic effects on GPCR trafficking, indicating that they played a major role in setting the trafficking itinerary of these GPCR. While endosomal SNX27, retromer/WASH complexes and actin were required for efficient sorting and budding of all these GPCR, additional proteins were required for GPCR sorting via the second "barcode". Here we will review recent developments in GPCR trafficking in general and the human β 1 -adrenergic receptor in particular across the various trafficking roadmaps. In addition, we will discuss the role of GPCR trafficking in regulating endosomal GPCR signaling, which promote biochemical and physiological effects that are distinct from those generated by the GPCR signal transduction

Seventeen years of human trafficking research in social work: A review of the literature.

Science.gov (United States)

Okech, David; Choi, Y Joon; Elkins, Jennifer; Burns, Abigail C

The trafficking of persons around the world is a serious violation of human rights and manifestation of social injustice. It disproportionately affects women and children worldwide. Given the values of the social work profession and the prevalence of trafficking, it is essential to understand the current literature on human trafficking in social work journals. Using the PRISMA method, this systematic review (n = 94 articles) of human trafficking in social work journals found the following: more focus on sex trafficking than other forms of trafficking; a lack of a clear conceptualization and definition on the entire spectrum of trafficking; a lack of evidence-informed empirical research to inform programs, practice, and policy; and a dearth of recommendations for social work education. Specific implications for social work policy, research, practice, and education are highlighted and discussed.

The 'dirty downside' of global sporting events: focus on human trafficking for sexual exploitation.

Science.gov (United States)

Finkel, R; Finkel, M L

2015-01-01

Human trafficking is as complex human rights and public health issue. The issue of human trafficking for sexual exploitation at large global sporting events has proven to be elusive given the clandestine nature of the industry. This piece examines the issue from a public health perspective. This is a literature review of the 'most comprehensive' studies published on the topic. A PubMed search was done using MeSH terms 'human traffickings' and 'sex trafficking' and 'human rights abuses'. Subheadings included 'statistics and numerical data', 'legislation and jurispudence', 'prevention and control', and 'therapy'. Only papers published in English were reviewed. The search showed that very few well-designed empirical studies have been conducted on the topic and only one pertinent systematic review was identified. Findings show a high prevalence of physical violence among those trafficked compared to non-trafficked women. Sexually transmitted infections and HIV AIDS are prevalent and preventive care is virtually non-existent. Quantifying human trafficking for sexual exploitation at large global sporting events has proven to be elusive given the clandestine nature of the industry. This is not to say that human trafficking for sex as well as forced sexual exploitation does not occur. It almost certainly exists, but to what extent is the big question. It is a hidden problem on a global scale in plain view with tremendous public health implications. Copyright © 2014 The Royal Society for Public Health. Published by Elsevier Ltd.

2017-04-01

As Nepal mourns the 1-year commemoration of the April 2015 earthquake and its aftershocks that killed more than 8500 people and left thousands injured and displaced, other more hidden repercussions of the resultant chaotic environment need attention: the increased risk of human trafficking. Considering that natural disasters provide a milieu for this illicit trade, there is a need for a robust response from stakeholders such as donors, civil society organizations, and government organizations against human trafficking following disasters such as the Nepal earthquake. Responsibility to prevent and fight trafficking should be explicitly included in the mandate of relief and rehabilitation mechanisms set up at the national level to coordinate the disaster relief response, serving to support populations in both rural and urban areas.

Intestinal brush border enzymes, including aminopeptidase N and sucrase-isomaltase, are associated with "rafts" (membrane microdomains rich in cholesterol and sphingoglycolipids). To assess the functional role of rafts in the present work, we studied the effect of cholesterol depletion on apical......, the rates of the Golgi-associated complex glycosylation and association with rafts of newly synthesized aminopeptidase N were reduced, and less of the enzyme had reached the brush border membrane after 2 h of labeling. In contrast, the basolateral Na(+)/K(+)-ATPase was neither missorted nor raft......-associated. Our results implicate the Golgi complex/trans-Golgi network in raft formation and suggest a close relationship between this event and apical membrane trafficking....

The molecular mechanisms of plant plasma membrane intrinsic proteins trafficking and stress response.

Science.gov (United States)

Wang, Xing; Zhang, Ji-long; Feng, Xiu-xiu; Li, Hong-jie; Zhang, Gen-fa

2017-04-20

Plasma membrane intrinsic proteins (PIPs) are plant channel proteins located on the plasma membrane. PIPs transfer water, CO 2 and small uncharged solutes through the plasma membrane. PIPs have high selectivity to substrates, suggestive of a central role in maintaining cellular water balance. The expression, activity and localization of PIPs are regulated at the transcriptional and post-translational levels, and also affected by environmental factors. Numerous studies indicate that the expression patterns and localizations of PIPs can change in response to abiotic stresses. In this review, we summarize the mechanisms of PIP trafficking, transcriptional and post-translational regulations, and abiotic stress responses. Moreover, we also discuss the current research trends and future directions on PIPs.

Human Sirtuin 2 Localization, Transient Interactions, and Impact on the Proteome Point to Its Role in Intracellular Trafficking.

Science.gov (United States)

Budayeva, Hanna G; Cristea, Ileana M

2016-10-01

Human sirtuin 2 (SIRT2) is an NAD + -dependent deacetylase that primarily functions in the cytoplasm, where it can regulate α-tubulin acetylation levels. SIRT2 is linked to cancer progression, neurodegeneration, and infection with bacteria or viruses. However, the current knowledge about its interactions and the means through which it exerts its functions has remained limited. Here, we aimed to gain a better understanding of its cellular functions by characterizing SIRT2 subcellular localization, the identity and relative stability of its protein interactions, and its impact on the proteome of primary human fibroblasts. To assess the relative stability of SIRT2 interactions, we used immunoaffinity purification in conjunction with both label-free and metabolic labeling quantitative mass spectrometry. In addition to the expected associations with cytoskeleton proteins, including its known substrate TUBA1A, our results reveal that SIRT2 specifically interacts with proteins functioning in membrane trafficking, secretory processes, and transcriptional regulation. By quantifying their relative stability, we found most interactions to be transient, indicating a dynamic SIRT2 environment. We discover that SIRT2 localizes to the ER-Golgi intermediate compartment (ERGIC), and that this recruitment requires an intact ER-Golgi trafficking pathway. Further expanding these findings, we used microscopy and interaction assays to establish the interaction and coregulation of SIRT2 with liprin-β1 scaffolding protein (PPFiBP1), a protein with roles in focal adhesions disassembly. As SIRT2 functions may be accomplished via interactions, enzymatic activity, and transcriptional regulation, we next assessed the impact of SIRT2 levels on the cellular proteome. SIRT2 knockdown led to changes in the levels of proteins functioning in membrane trafficking, including some of its interaction partners. Altogether, our study expands the knowledge of SIRT2 cytoplasmic functions to define a

Modulation of epithelial sodium channel trafficking and function by sodium 4-phenylbutyrate in human nasal epithelial cells.

Science.gov (United States)

Prulière-Escabasse, Virginie; Planès, Carole; Escudier, Estelle; Fanen, Pascale; Coste, André; Clerici, Christine

2007-11-23

Sodium 4-phenylbutyrate (4-PBA) has been shown to correct the cellular trafficking of several mutant or nonmutant plasma membrane proteins such as cystic fibrosis transmembrane conductance regulator through the expression of 70-kDa heat shock proteins. The objective of the study was to determine whether 4-PBA may influence the functional expression of epithelial sodium channels (ENaC) in human nasal epithelial cells (HNEC). Using primary cultures of HNEC, we demonstrate that 4-PBA (5 mm for 6 h) markedly stimulated amiloride-sensitive sodium channel activity and that this was related to an increased abundance of alpha-, beta-, and gamma-ENaC subunits in the apical membrane. The increase in ENaC cell surface expression (i) was due to insertion of newly ENaC subunits as determined by brefeldin A experiments and (ii) was not associated with cell surface retention of ENaC subunits because endocytosis of ENaC subunits was unchanged. In addition, we find that ENaC co-immunoprecipitated with the heat shock protein constitutively expressed Hsc70, that has been reported to modulate ENaC trafficking, and that 4-PBA decreased Hsc70 protein level. Finally, we report that in cystic fibrosis HNEC obtained from two cystic fibrosis patients, 4-PBA increased functional expression of ENaC as demonstrated by the increase in amiloride-sensitive sodium transport and in alpha-, beta-, and gamma-ENaC subunit expression in the apical membrane. Our results suggest that in HNEC, 4-PBA increases the functional expression of ENaC through the insertion of new alpha-, beta-, and gamma-ENaC subunits into the apical membrane and also suggest that 4-PBA could modify ENaC trafficking by reducing Hsc70 protein expression.

Nurses' Perceptions of Victims of Human Trafficking in an Urban Emergency Department: A Qualitative Study.

Science.gov (United States)

Long, Elizabeth; Dowdell, Elizabeth B

2017-12-15

Human trafficking is estimated to surpass the drug trade as the leading illegal industry in the world. According to a recent study, over 87.8% of trafficking survivors came into contact with a healthcare professional while they were enslaved and were not identified as a victim of human trafficking. The aims of this study are to understand the perceptions of emergency nurses about human trafficking, victims of violence, and prostitution. A qualitative, descriptive study using a semi-structured interview approach was done with ten registered nurses in a large, urban Emergency Department in the northeastern U.S. Interviews were recorded and transcribed; thematic analysis was performed. Six themes emerged from the interviews including, "human trafficking exists in the patient population" yet no nurse has screened or treated a victim; human trafficking victims are perceived to be "young, female, and foreign born"; all of the emergency nurses reported having worked with or screened a victim of violence; victims of violence were viewed as patients who present as "sad and grieving"; prostitutes are seen as "hard and tough"; and emergency nurses did not have education on human trafficking victims' needs or resources. Emergency nurses should be more aware about victims of human trafficking. The media portrayal of human trafficking victims had influenced the nurses' perceptions of this population. Victims of violence are perceived to be very different from prostitutes, but there is a desire for education about violence as well as information about specific resources open to victims.

Human trafficking and health: a conceptual model to inform policy, intervention and research.

Science.gov (United States)

Zimmerman, Cathy; Hossain, Mazeda; Watts, Charlotte

2011-07-01

Human trafficking is an international crime renowned for extreme forms of violence against women, men and children. Although trafficking-related violence has been well-documented, the health of trafficked persons has been a largely neglected topic. For people who are trafficked, health risks and consequences may begin before they are recruited into the trafficking process, continue throughout the period of exploitation and persist even after individuals are released. Policy-making, service provision and research often focus narrowly on criminal violations that occur during the period of exploitation, regularly overlooking the health implications of trafficking. Similarly, the public health sector has not yet incorporated human trafficking as a health concern. We present a conceptual model that highlights the migratory and exploitative nature of a multi-staged trafficking process, which includes: 'recruitment', travel-transit', 'exploitation' and 'integration' or 'reintegration', and for some trafficked persons, 'detention' and 're-trafficking' stages. Trafficked persons may suffer from physical, sexual and psychological harm, occupational hazards, legal restrictions and difficulties associated with being marginalised or stigmatised. Researchers and decision-makers will benefit from a theoretical approach that conceptualizes trafficking and health as a multi-staged process of cumulative harm. To address a health risk such as trafficking, which spans geographical boundaries and involves multiple sectors, including immigration and law enforcement, labour, social and health services, interventions must be coordinated between nations and across sectors to promote the protection and recovery of people who are trafficked.

Hypothesis review: are clathrin-mediated endocytosis and clathrin-dependent membrane and protein trafficking core pathophysiological processes in schizophrenia and bipolar disorder?

LENUS (Irish Health Repository)

2012-02-01

Clathrin-mediated endocytosis (CME) is the best-characterized mechanism governing cellular membrane and protein trafficking. In this hypothesis review, we integrate recent evidence implicating CME and related cellular trafficking mechanisms in the pathophysiology of psychotic disorders such as schizophrenia and bipolar disorder. The evidence includes proteomic and genomic findings implicating proteins and genes of the clathrin interactome. Additionally, several important candidate genes for schizophrenia, such as dysbindin, are involved in processes closely linked to CME and membrane trafficking. We discuss that key aspects of psychosis neuropathology such as synaptic dysfunction, white matter changes and aberrant neurodevelopment are all influenced by clathrin-dependent processes, and that other cellular trafficking mechanisms previously linked to psychoses interact with the clathrin interactome in important ways. Furthermore, many antipsychotic drugs have been shown to affect clathrin-interacting proteins. We propose that the targeted pharmacological manipulation of the clathrin interactome may offer fruitful opportunities for novel treatments of schizophrenia.Molecular Psychiatry advance online publication, 11 October 2011; doi:10.1038\\/mp.2011.123.

National Human Trafficking Initiatives: Dimensions of Policy Diffusion1

Science.gov (United States)

Yoo, Eun-hye; Boyle, Elizabeth Heger

2014-01-01

The implementation of criminal law involves formal law enforcement, education and public outreach aimed at preventing criminal activity, and providing services for victims. Historically, quantitative research on global trends has tended to focus on a single policy dimension, potentially masking the unique factors that affect the diffusion of each policy dimension independently. Using an ordered-probit model to analyze new human trafficking policy data on national prosecution, prevention, and victim-protection efforts, we find that global ties and domestic interest groups matter more in areas where international law is less defined. While prosecution, officially mandated by the Trafficking Protocol, was relatively impervious to global ties and domestic interest groups, both trafficking prevention and victim protection were associated with these factors. Our findings also suggest that fear of repercussions is not a major driver of state actions to combat trafficking—neither ratification of the Trafficking Protocol nor levels of United States aid were associated with greater implementation of anti-trafficking measures.

Ist2 in the yeast cortical endoplasmic reticulum promotes trafficking of the amino acid transporter Bap2 to the plasma membrane.

Directory of Open Access Journals (Sweden)

Wendelin Wolf

Full Text Available The equipment of the plasma membrane in Saccharomyces cerevisiae with specific nutrient transporters is highly regulated by transcription, translation and protein trafficking allowing growth in changing environments. The activity of these transporters depends on a H(+ gradient across the plasma membrane generated by the H(+-ATPase Pma1. We found that the polytopic membrane protein Ist2 in the cortical endoplasmic reticulum (ER is required for efficient leucine uptake during the transition from fermentation to respiration. Experiments employing tandem fluorescence timer protein tag showed that Ist2 was necessary for efficient trafficking of newly synthesized leucine transporter Bap2 from the ER to the plasma membrane. This finding explains the growth defect of ist2Δ mutants during nutritional challenges and illustrates the important role of physical coupling between cortical ER and plasma membrane.

The Prominent Role of National Judges in Interpreting the International Definition of Human Trafficking

Directory of Open Access Journals (Sweden)

Luuk B Esser

2016-05-01

Full Text Available Although there has been much discussion of the scope of the concept of human trafficking in international literature, the part played by national courts in interpreting definitions based on the international definition of human trafficking in the UN Trafficking Protocol has received little attention. When a judge interprets an offence, he or she clarifies or adds new meaning to it. The space for this is even greater when the underlying definition is broadly formulated, as in the case of the international definition of human trafficking. This article demonstrates that, although this international definition establishes the outer parameters within which conduct must be made a criminal offence, domestic courts still have room to flesh out the definition in national contexts. The role of national judges needs more consideration in today’s discourse on the legal definition of human trafficking.

Identifying Victims of Human Trafficking at Hotspots by Focusing on People Smuggled to Europe

Directory of Open Access Journals (Sweden)

Matilde Ventrella

2017-06-01

Full Text Available Research has shown that smuggling of migrants is associated with human trafficking. Hence, victims of human trafficking amongst smuggled migrants should be identified by EU Member States at hotspots established by the European Commission, to overcome the migrant and refugee crisis. Identified victims should be given a visa and a programme of protection to escape their traffickers. In order to achieve these objectives, research suggests that EU law on migrant smuggling should be amended and the Temporary Protection Directive should be applied to smuggled persons when there is an indication that they may be victims of human trafficking. This approach should be adopted by the EASO in cooperation with police forces investigating smuggling and trafficking at hotspots.

2016-06-01

The medical sector presents a unique opportunity for identification and service to victims of human trafficking. In this article, we describe local and site-specific efforts to develop an intervention tool to be used in an urban hospital's emergency department in the midwestern United States. In the development of our tool, we focused on both identification and intervention to assist trafficked persons, through a largely collaborative process in which we engaged local stakeholders for developing site-specific points of intervention. In the process of developing our intervention, we highlight the importance of using existing resources and services in a specific community to address critical gaps in coverage for trafficked persons. For example, we focus on those who are victims of labor trafficking, in addition to those who are victims of sex trafficking. We offer a framework informed by rights-based approaches to anti-trafficking efforts that addresses the practical challenges of human trafficking victim identification while simultaneously working to provide resources and disseminate services to those victims.

Egyud, Amber; Stephens, Kimberly; Swanson-Bierman, Brenda; DiCuccio, Marge; Whiteman, Kimberly

2017-11-01

Health care professionals have not been successful in recognizing or rescuing victims of human trafficking. The purpose of this project was to implement a screening system and treatment algorithm in the emergency department to improve the identification and rescue of victims of human trafficking. The lack of recognition by health care professionals is related to inadequate education and training tools and confusion with other forms of violence such as trauma and sexual assault. A multidisciplinary team was formed to assess the evidence related to human trafficking and make recommendations for practice. After receiving education, staff completed a survey about knowledge gained from the training. An algorithm for identification and treatment of sex trafficking victims was implemented and included a 2-pronged identification approach: (1) medical red flags created by a risk-assessment tool embedded in the electronic health record and (2) a silent notification process. Outcome measures were the number of victims who were identified either by the medical red flags or by silent notification and were offered and accepted intervention. Survey results indicated that 75% of participants reported that the education improved their competence level. The results demonstrated that an education and treatment algorithm may be an effective strategy to improve recognition. One patient was identified as an actual victim of human trafficking; the remaining patients reported other forms of abuse. Education and a treatment algorithm were effective strategies to improve recognition and rescue of human trafficking victims and increase identification of other forms of abuse.

Cytokinesis is a highly ordered process that divides one cell into two cells, which is functionally linked to the dynamic remodeling of the plasma membrane coordinately with various events such as membrane trafficking. Calcineurin is a highly conserved serine/threonine protein phosphatase, which regulates multiple biological functions, such as membrane trafficking and cytokinesis. Here, we isolated imp2-c3, a mutant allele of the imp2 + gene, encoding a homolog of the mouse PSTPIP1 (proline-serine-threonine phosphatase interacting protein 1), using a genetic screen for mutations that are synthetically lethal with calcineurin deletion in fission yeast. The imp2-c3 mutants showed a defect in cytokinesis with multi-septated phenotypes, which was further enhanced upon treatment with the calcineurin inhibitor FK506. Notably, electron micrographs revealed that the imp2-c3 mutant cells accumulated aberrant multi-lamella Golgi structures and putative post-Golgi secretory vesicles, and exhibited fragmented vacuoles in addition to thickened septa. Consistently, imp2-c3 mutants showed a reduced secretion of acid phosphatase and defects in vacuole fusion. The imp2-c3 mutant cells exhibited a weakened cell wall, similar to the membrane trafficking mutants identified in the same genetic screen such as ypt3-i5. These findings implicate the PSTPIP1 homolog Imp2 in Golgi/vacuole function, thereby affecting various cellular processes, including cytokinesis and cell integrity. - Highlights: • We isolated imp2-c3, in a synthetic lethal screen with calcineurin in fission yeast. • The imp2 + gene encodes a component of the actin contractile ring similar to Cdc15. • The imp2-c3 mutants showed defects in cytokinesis, which were exacerbated by FK506. • The imp2-c3 mutants were defective in membrane trafficking and cell wall integrity. • Our study revealed a novel role for Imp2 in the Golgi/vacuolar membrane trafficking

Gordon, Mollie; Salami, Temilola; Coverdale, John; Nguyen, Phuong T

2018-03-01

Human trafficking is an outrageous human rights violation with potentially devastating consequences to individuals and the public health. Victims are often underrecognized and there are few guidelines for how best to identify, care for, and safely reintegrate victims back into the community. The purpose of this paper is to propose a multifaceted, interdisciplinary, and interprofessional guideline for providing care and services to human trafficking victims. Databases such as PubMed and PsycINFO were searched for papers outlining human trafficking programs with a primary psychiatric focus. No integrated care models that provide decisional guidelines at different points of intervention for human trafficking patients and that highlight the important role of psychiatric consultation were found. Psychiatrists and psychologists are pivotal to an integrated care approach in health care settings. The provision of such a comprehensive and integrated model of care should facilitate the identification of victims, promote their recovery, and reduce the possibility of retraumatization.

Fragile X Mental Retardation Protein Regulates Activity-Dependent Membrane Trafficking and Trans-Synaptic Signaling Mediating Synaptic Remodeling

Science.gov (United States)

Sears, James C.; Broadie, Kendal

2018-01-01

Fragile X syndrome (FXS) is the leading monogenic cause of autism and intellectual disability. The disease arises through loss of fragile X mental retardation protein (FMRP), which normally exhibits peak expression levels in early-use critical periods, and is required for activity-dependent synaptic remodeling during this transient developmental window. FMRP canonically binds mRNA to repress protein translation, with targets that regulate cytoskeleton dynamics, membrane trafficking, and trans-synaptic signaling. We focus here on recent advances emerging in these three areas from the Drosophila disease model. In the well-characterized central brain mushroom body (MB) olfactory learning/memory circuit, FMRP is required for activity-dependent synaptic remodeling of projection neurons innervating the MB calyx, with function tightly restricted to an early-use critical period. FMRP loss is phenocopied by conditional removal of FMRP only during this critical period, and rescued by FMRP conditional expression only during this critical period. Consistent with FXS hyperexcitation, FMRP loss defects are phenocopied by heightened sensory experience and targeted optogenetic hyperexcitation during this critical period. FMRP binds mRNA encoding Drosophila ESCRTIII core component Shrub (human CHMP4 homolog) to restrict Shrub translation in an activity-dependent mechanism only during this same critical period. Shrub mediates endosomal membrane trafficking, and perturbing Shrub expression is known to interfere with neuronal process pruning.

Exocyst and autophagy-related membrane trafficking in plants.

Endomembrane traffic in eukaryotic cells functions partially as a means of communication; delivery of membrane in one direction has to be balanced with a reduction at the other end. This effect is typically the case during the defence against pathogens. To combat pathogens, cellular growth and differentiation are suppressed, while endomembrane traffic is poised towards limiting the pathogen attack. The octameric exocyst vesicle-tethering complex was originally discovered as a factor facilitating vesicle-targeting and vesicle-plasma membrane (PM) fusion during exocytosis prior to and possibly during SNARE complex formation. Interestingly, it was recently implicated both in animals and plants in autophagy membrane traffic. In animal cells, the exocyst is integrated into the mTOR-regulated energy metabolism stress/starvation pathway, participating in the formation and especially initiation of an autophagosome. In plants, the first functional link was to autophagy-related anthocyanin import to the vacuole and to starvation. In this concise review, we summarize the current knowledge of exocyst functions in autophagy and defence in plants that might involve unconventional secretion and compare it with animal conditions. Formation of different exocyst complexes during undisturbed cell growth, as opposed to periods of cellular stress reactions involving autophagy, might contribute to the coordination of endomembrane trafficking pathways. © The Author(s) 2017.

Mirela Kapo

2017-07-01

Full Text Available The topic “Trafficking of human beings” as subject to advanced studies has been chosen due to a growing interest linked with the phenomenon in question. The study introduces a legal criminal overview of the criminal activity consisted of the recruitment, transport, transfer or reception of persons by means of force or forms of fraud for exploitation purposes. Human trafficking represents a threat for the security of member states. The trend to penetrate to all spheres of the society has obliged the European states to draft a new directive reflecting the growing concern about the phenomenon in question, by respecting human rights in accordance with the legal framework under the United Nations, International Labor Organization (ILO, and Council of Europe etc. The new European priorities aim at victims’ identification, their protection and prevention of the phenomenon and more intense criminal prosecution of traffickers. With the view of fully developing this topic, the outline consists of four chapters preceded by a historical background of human trafficking. Special importance in this study, specifically in the second chapter, is attached to the assistance and protection of the victims of human trafficking. It is crucial that these victims exercise their rights effectively. Therefore, the European directives foresee assistance and support before, after and during the criminal proceeding. The third chapter refers to the relevant legal mechanisms in this field assuring the victims of trafficking legal defense, the right to information and their social, psychological and physical recovery. One of the “key” legal instruments is the Palermo Convention, which gives for the first time a detailed definition of the term of trafficking and smuggling and makes the differences between them. All legal instruments converge to one point: the consent of the human trafficking victim is not important when it is used any of the means of force, threat

Full Text Available The article deals with the combat of forced labor and human trafficking in Central Asia. It is noted that this problem has emerged since the early 90s, when these countries got the independence, due to the difficult economic situation, activity of extremist organizations. It is pointed out that the victims of trafficking may be men, women and children, but in most cases they are young women and girls who are sexually exploited. It is shown by the examples of each of the countries of the region, what is being done to counter this terrible phenomenon. The Government of the Republic of Tajikistan established the Interdepartmental Commission to Combat Human Trafficking. The commission, in cooperation with international organizations doing some work to inform the public, the search for victims of sexual business, return and rehabilitation of these persons. In Kazakhstan, according to the new law it has become easier to initiate criminal proceedings concerning labor slavery. In addition, a temporary accommodation center for victims of human trafficking «Komek» was created. In Kyrgyzstan, a working group on the development of 3 of the National Action Plan to Combat Trafficking in Human Beings (2011-2015 under the auspices of the Ministry of Labour, Employment and Migration of the Kyrgyz Republic was created. In Uzbekistan, the law «on combating human trafficking» came into force. In addition, a Republican Interdepartmental Commission to Combat Human Trafficking was created. The law defines the powers of public authorities directly involved in the activities in this direction. In Turkmenistan, the government prohibits all forms of trafficking of persons in accordance with Article 129 of the Criminal Code, adopted in May 2010 and entered into force in July 2010. It provides for penalties ranging from 4 to 25 years in prison. These penalties sufficiently stringent and commensurate with penalties prescribed for other serious crimes, such as rape. At

Routes of human trafficking in Europe and the position of Serbia on them

Full Text Available Human trafficking as a form of organized crime is showing its increase today, changing at the same time its structure and characteristics. Some factors that contribute to such a situation are global trends that result in huge social and economic inequalities in the world, but also turbulences and problems that are affecting certain regions (wars, political instability, ethnic conflicts, militarization etc.. Human trafficking, as a complex social phenomenon that encompasses different forms of acting, subjects and aims, can be analyzed within different concepts. One of them refers to the issue of broader migration flows and migration control policy. Namely, from the global perspective, trafficking in human beings can be mostly considered as a form of 'organized illegal migration'. Due to that, it seems important to consider the issue of routes through which this form of migration is realized today. Discovering human trafficking routes, as well as other forms of illegal movement of people and illegal forms of trade are very important from the point of view of implementing adequate measures and relocation of resources in order to suppress these forms of socially unacceptable phenomena. Creating adequate anti-trafficking activities is important on national, regional and international levels. Keeping that in mind, the aim of this paper is to look into the contemporary routes of human trafficking within Europe and find out what is the position of Serbia on these routes, as well to examine possible changes that happened in this field during past several years. This will be done on the basis of the analysis of relevant literature, as well as on some preliminary findings of the survey on male victims of human trafficking in Serbia, which is currently conducted by the Victimology Society of Serbia.

IRREGULAR MIGRATION FLOWS AND HUMAN TRAFFICKING IN THE WESTERN BALKAN COUNTRIES: CHALLENGES OF THE CONVERGENCE OF COUNTER-TRAFFICKING RESPONSE

Directory of Open Access Journals (Sweden)

Merita H. Mece

2016-05-01

Full Text Available Irregular migration on the Western Balkan route has marked an unprecedented number during the last five years. Evidence indicates that both, non-European nationals and Western Balkan citizens have been involved in this complex migratory flow being exposed to various risks of human trafficking. But Western Balkan countries are source, transit and destination countries of human trafficking while their states are not well organized to implement a comprehensive and well-coordinated regional response to combat it. This paper aims at examining challenges faced by the Western Balkan countries to converge anti-trafficking response while facing increased irregular migratory waves. Using secondary data it illustrates various disparities and differences among them concluding that a well-coordinated, multi-faceted and integrated regional response is needed to combat this humanitarian problem.

Cellular Localization and Trafficking of the Human ABCG1 Transporter

Neufeld, Edward B.; O’Brien, Katherine; Walts, Avram D.; Stonik, John A.; Demosky, Steven J.; Malide, Daniela; Combs, Christian A.; Remaley, Alan T.

2014-01-01

We have developed a suitable heterologous cell expression system to study the localization, trafficking, and site(s) of function of the human ABCG1 transporter. Increased plasma membrane (PM) and late endosomal (LE) cholesterol generated by ABCG1 was removed by lipoproteins and liposomes, but not apoA-I. Delivery of ABCG1 to the PM and LE was required for ABCG1-mediated cellular cholesterol efflux. ABCG1 LEs frequently contacted the PM, providing a collisional mechanism for transfer of ABCG1-mobilized cholesterol, similar to ABCG1-mediated PM cholesterol efflux to lipoproteins. ABCG1-mobilized LE cholesterol also trafficked to the PM by a non-vesicular pathway. Transfer of ABCG1-mobilized cholesterol from the cytoplasmic face of LEs to the PM and concomitant removal of cholesterol from the outer leaflet of the PM bilayer by extracellular acceptors suggests that ABCG1 mobilizes cholesterol on both sides of the lipid bilayer for removal by acceptors. ABCG1 increased uptake of HDL into LEs, consistent with a potential ABCG1-mediated cholesterol efflux pathway involving HDL resecretion. Thus, ABCG1 at the PM mobilizes PM cholesterol and ABCG1 in LE/LYS generates mobile pools of cholesterol that can traffic by both vesicular and non-vesicular pathways to the PM where it can also be transferred to extracellular acceptors with a lipid surface.

Houston-Kolnik, Jaclyn D; Soibatian, Christina; Shattell, Mona M

2017-02-01

The present qualitative study explores advocates' opinions of misinformation about human trafficking in the media and describes advocates' strategies to counter the misinformation presented by the media. Thus, 15 advocates who work against human trafficking in Chicago-based nonprofit organizations participated in semistructured interviews about their opinions and strategies. Data were analyzed using thematic content analysis. The present study identifies specific misperceptions of human trafficking in the media, highlights advocates' opinions of this misinformation, and discusses advocates' strategies to counteract inaccurate media, adding support to the role of media advocacy. Advocates note how media images shape and perpetuate stereotypes of trafficking through glamorizing sex work and sensationalizing stories that are most often international depictions of trafficking. Advocates report media generally shares only a piece of the story, simplifying the stories of survivors and the issue of human trafficking. Advocates critique media perpetuating these misperceptions for how they may contribute to policies and programs which fail to address structural factors that create vulnerabilities to be trafficked and the multisystem needs of survivors. However, advocates also note misperceptions can be counteracted by producing sensitive, informed media through social platforms. Advocates share their strategies counteracting misinformation through engaging in informative conversations, utilizing social media to educate, and promoting media messages of survivor agency. Research, clinical, and policy implications are also discussed. The present study emphasizes the importance of decision makers and service providers being critical consumers of media and to assess how media portrayals may (or may not) inform their understanding and response to the issue.

People for sale: the need for a multidisciplinary approach towards human trafficking.

Science.gov (United States)

Van Impe, K

2000-01-01

The article addresses the question of how to develop appropriate measures to tackle trafficking in women, based on the findings of a study of trafficking between the Philippines and Belgium. It argues that there is no easy or unidimensional solution to human trafficking, since it is influenced by a complex set of factors, often working in combination with one another. It concludes that control measures alone cannot stop the flow of trafficking in women and that a legal approach which relies solely on one type of legislation would be too narrow. An effective strategy must combine and balance punitive measures with protection of human rights, stricter border control and the removal of the root causes of irregular movements. Measures must be agreed and coordinated between origin, transit and receiving countries.

Human Trafficking and National Morality

Directory of Open Access Journals (Sweden)

William R. DI PIETRO

2015-12-01

Full Text Available The paper proposes that national morality is an important variable for explaining national anti-trafficking policy. It uses cross country regression analysis to see whether or not empirically national morality is a determinant of anti-trafficking policy. The findings of the paper are consistent with the notion that improved levels of national morality lead to better national anti-trafficking policy. National morality is found to be statistically relevant for national anti-trafficking policy when controlling for the extent of democracy, the share of the private sector in the economy, and the degree of globalization.

Cellular membrane trafficking of mesoporous silica nanoparticles

Energy Technology Data Exchange (ETDEWEB)

Fang, I-Ju [Iowa State Univ., Ames, IA (United States)

2012-01-01

This dissertation mainly focuses on the investigation of the cellular membrane trafficking of mesoporous silica nanoparticles. We are interested in the study of endocytosis and exocytosis behaviors of mesoporous silica nanoparticles with desired surface functionality. The relationship between mesoporous silica nanoparticles and membrane trafficking of cells, either cancerous cells or normal cells was examined. Since mesoporous silica nanoparticles were applied in many drug delivery cases, the endocytotic efficiency of mesoporous silica nanoparticles needs to be investigated in more details in order to design the cellular drug delivery system in the controlled way. It is well known that cells can engulf some molecules outside of the cells through a receptor-ligand associated endocytosis. We are interested to determine if those biomolecules binding to cell surface receptors can be utilized on mesoporous silica nanoparticle materials to improve the uptake efficiency or govern the mechanism of endocytosis of mesoporous silica nanoparticles. Arginine-glycine-aspartate (RGD) is a small peptide recognized by cell integrin receptors and it was reported that avidin internalization was highly promoted by tumor lectin. Both RGD and avidin were linked to the surface of mesoporous silica nanoparticle materials to investigate the effect of receptor-associated biomolecule on cellular endocytosis efficiency. The effect of ligand types, ligand conformation and ligand density were discussed in Chapter 2 and 3. Furthermore, the exocytosis of mesoporous silica nanoparticles is very attractive for biological applications. The cellular protein sequestration study of mesoporous silica nanoparticles was examined for further information of the intracellular pathway of endocytosed mesoporous silica nanoparticle materials. The surface functionality of mesoporous silica nanoparticle materials demonstrated selectivity among the materials and cancer and normal cell lines. We aimed to determine

Quantification of the Force of Nanoparticle-Cell Membrane Interactions and Its Influence on Intracellular Trafficking of Nanoparticles

Science.gov (United States)

Vasir, Jaspreet K.; Labhasetwar, Vinod

2008-01-01

Understanding the interaction of nanoparticles (NPs) with the cell membrane and their trafficking through cells is imperative to fully explore the use of NPs for efficient intracellular delivery of therapeutics. Here, we report a novel method of measuring the force of NP-cell membrane interactions using atomic force microscopy (AFM). Poly(dl-lactide co-glycolide, PLGA) NPs functionalized with poly-l-lysine were used as a model system, to demonstrate that this force determines the adhesive interaction of NPs with the cell membrane and in turn the extent of cellular uptake of NPs, and hence that of the encapsulated therapeutic. Cellular uptake of NPs was monitored using AFM imaging, and the dynamics of their intracellular distribution was quantified using confocal microscopy. Results demonstrated that the functionalized NPs have a five-fold greater force of adhesion with the cell membrane and the time-lapse AFM images show their rapid internalization than unmodified NPs. The intracellular trafficking study showed that the functionalized NPs escape more rapidly and efficiently from late endosomes than unmodified NPs and result in 10-fold higher intracellular delivery of the encapsulated model protein. The findings described herein enhance our basic understanding of the NP-cell membrane interaction on the basis of physical phenomena that could have wider applications in developing efficient nanocarrier systems for intracellular delivery of therapeutics.

Rebooting Trafficking

Nicholas de Villiers

2016-09-01

Full Text Available While popular psychology and appeals to emotion have unfortunately dominated discussions of ‘sex trafficking’, this article suggests that feminist psychoanalytic film theory and theories of affect are still useful for making sense of the appeal of sensational exposés like Lifetime Television’s Human Trafficking (2005. The dynamic of identification with (and impersonation of a human trafficking ‘victim’ by the rescuing Immigration and Customs Enforcement agent (Mira Sorvino is particularly worthy of scrutiny. Film theory about the ‘rebooting’ of film franchises (iconic brands like Batman also helps explain the preponderance of similar programming—Sex Slaves (2005, Selling the Girl Next Door (2011, Trafficked (2016—and the way contemporary discourses of human trafficking have effectively rebranded the myth of ‘white slavery’.

Identification and Treatment of Human Trafficking Victims in the Emergency Department: A Case Report.

Science.gov (United States)

Gibbons, Patric; Stoklosa, Hanni

2016-05-01

Human trafficking victims experience extreme exploitation and have unique health needs, yet too often go undetected by physicians and providers in the Emergency Department (ED). We report a clinical case of human trafficking of a white, English-speaking United States citizen and discuss the features of presentation and treatment options for human trafficking victims upon presentation to the ED. A 29-year-old woman with a past medical history significant for intravenous drug abuse and recent relapse presented to the ED after a reported sexual assault. The patient was discharged that evening and returned to the ED the following day acutely suicidal. The patient divulged that she had been kidnapped and raped at gunpoint by numerous individuals as a result of a debt owed to her drug dealers. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Many human trafficking victims present to an ED during the course of their exploitation. To that end, EDs provide one of a limited set of opportunities to intervene in the human trafficking cycle of exploitation, and physicians as well as other ED staff should be equipped to respond.

Alterations in membrane trafficking and pathophysiological implications in lysosomal storage disorders.

Science.gov (United States)

Kuech, Eva-Maria; Brogden, Graham; Naim, Hassan Y

2016-11-01

Lysosomal storage disorders are a heterogeneous group of more than 50 distinct inborn metabolic diseases affecting about 1 in 5000 to 7000 live births. The diseases often result from mutations followed by functional deficiencies of enzymes or transporters within the acidic environment of the lysosome, which mediate the degradation of a wide subset of substrates, including glycosphingolipids, glycosaminoglycans, cholesterol, glycogen, oligosaccharides, peptides and glycoproteins, or the export of the respective degradation products from the lysosomes. The progressive accumulation of uncleaved substrates occurs in multiple organs and finally causes a broad spectrum of different pathologies including visceral, neurological, skeletal and hematologic manifestations. Besides deficient lysosomal enzymes and transporters other defects may lead to lysosomal storage disorders, including activator defects, membrane defects or defects in modifier proteins. In this review we concentrate on four different lysosomal storage disorders: Niemann-Pick type C, Fabry disease, Gaucher disease and Pompe disease. While the last three are caused by defective lysosomal hydrolases, Niemann-Pick type C is caused by the inability to export LDL-derived cholesterol out of the lysosome. We want to emphasise potential implications of membrane trafficking defects on the pathology of these diseases, as many mutations interfere with correct lysosomal protein trafficking and alter cellular lipid homeostasis. Current therapeutic strategies are summarised, including substrate reduction therapy as well as pharmacological chaperone therapy which directly aim to improve folding and lysosomal transport of misfolded mutant proteins.

2012-11-01

We propose an iterative and human-centred knowledge discovery methodology based on formal concept analysis. The proposed approach recognizes the important role of the domain expert in mining real-world enterprise applications and makes use of specific domain knowledge, including human intelligence and domain-specific constraints. Our approach was empirically validated at the Amsterdam-Amstelland police to identify suspects and victims of human trafficking in 266,157 suspicious activity reports. Based on guidelines of the Attorney Generals of the Netherlands, we first defined multiple early warning indicators that were used to index the police reports. Using concept lattices, we revealed numerous unknown human trafficking and loverboy suspects. In-depth investigation by the police resulted in a confirmation of their involvement in illegal activities resulting in actual arrestments been made. Our human-centred approach was embedded into operational policing practice and is now successfully used on a daily basis to cope with the vastly growing amount of unstructured information.

2016-07-19

Previous studies have found a high prevalence of depression and post-traumatic stress disorder (PTSD) among survivors of human trafficking. European countries are required to assist trafficked people in their psychological recovery, but there are no rigorous data on the costs of doing so. The objectives of this study were to quantify the use of secondary mental health services by survivors of human trafficking; to estimate the cost of survivors' use of secondary mental health services provided by the UK National Health Service (NHS); and to identify factors that predict higher costs of mental health service provision. Historical cohort study of psychiatric patients who had experienced human trafficking. The South London and Maudsley NHS Trust (SLaM) Biomedical Research Centre Case Register Interactive Search (CRIS) database was used to identify anonymised full patient records of patients who had experienced human trafficking and who had accessed SLaM mental health services between 2007 and 2012. Data were extracted on socio-demographic and trafficking characteristics and contacts with mental health services. Total costs were calculated by multiplying each resource use item by an appropriate unit cost. Factors that predicted high mental health service costs were analysed using regression models. One hundred nineteen patients were included in the analysis. Mean total mental health service costs per patient were £27,293 (sd 80,985) and mean duration of contact with services was 1490 (sd 757) days (approximately 4 years). Regression analysis showed that higher costs were associated with diagnosis of psychotic disorder (p trafficking violence (p = 0.06). Patients diagnosed with psychotic disorders cost approximately £32,635 more than patients with non-psychotic disorders/psychological distress but no formal diagnosis and patients whose clinical notes documented pre-trafficking violence cost £88,633 more than patients for whom pre-trafficking violence was not

Membrane Trafficking of Death Receptors: Implications on Signalling

Directory of Open Access Journals (Sweden)

Wulf Schneider-Brachert

2013-07-01

Full Text Available Death receptors were initially recognised as potent inducers of apoptotic cell death and soon ambitious attempts were made to exploit selective ignition of controlled cellular suicide as therapeutic strategy in malignant diseases. However, the complexity of death receptor signalling has increased substantially during recent years. Beyond activation of the apoptotic cascade, involvement in a variety of cellular processes including inflammation, proliferation and immune response was recognised. Mechanistically, these findings raised the question how multipurpose receptors can ensure selective activation of a particular pathway. A growing body of evidence points to an elegant spatiotemporal regulation of composition and assembly of the receptor-associated signalling complex. Upon ligand binding, receptor recruitment in specialized membrane compartments, formation of receptor-ligand clusters and internalisation processes constitute key regulatory elements. In this review, we will summarise the current concepts of death receptor trafficking and its implications on receptor-associated signalling events.

Scott W. Messenger

2015-11-01

Full Text Available Background & Aims: Pancreatic acinar cells have an expanded apical endosomal system, the physiologic and pathophysiologic significance of which is still emerging. Phosphatidylinositol-3,5-bisphosphate [PI(3,5P2] is an essential phospholipid generated by phosphatidylinositol 3-phosphate 5-kinase (PIKfyve, which phosphorylates phosphatidylinositol-3-phosphate (PI3P. PI(3,5P2 is necessary for maturation of early endosomes (EE to late endosomes (LE. Inhibition of EE to LE trafficking enhances anterograde endosomal trafficking and secretion at the plasma membrane by default through a recycling endosome (RE intermediate. We assessed the effects of modulating PIKfyve activity on apical trafficking and pancreatitis responses in pancreatic acinar cells. Methods: Inhibition of EE to LE trafficking was achieved using pharmacologic inhibitors of PIKfyve, expression of dominant negative PIKfyve K1877E, or constitutively active Rab5-GTP Q79L. Anterograde endosomal trafficking was manipulated by expression of constitutively active and dominant negative Rab11a mutants. The effects of these agents on secretion, endolysosomal exocytosis of lysosome associated membrane protein (LAMP1, and trypsinogen activation in response to supramaximal cholecystokinin (CCK-8, bile acids, and cigarette toxin was determined. Results: PIKfyve inhibition increased basal and stimulated secretion. Adenoviral overexpression of PIKfyve decreased secretion leading to cellular death. Expression of Rab5-GTP Q79L or Rab11a-GTP Q70L enhanced secretion. Conversely, dominant-negative Rab11a-GDP S25N reduced secretion. High-dose CCK inhibited endolysosomal exocytosis that was reversed by PIKfyve inhibition. PIKfyve inhibition blocked intracellular trypsin accumulation and cellular damage responses to supramaximal CCK-8, tobacco toxin, and bile salts in both rodent and human acini. Conclusions: These data demonstrate that EE-LE trafficking acutely controls acinar secretion and the intracellular

Training US health care professionals on human trafficking: where do we go from here?

Powell, Clydette; Dickins, Kirsten; Stoklosa, Hanni

2017-01-01

Some 21 million adults and children are labor-trafficked or sex-trafficked through force, fraud, or coercion. In recognition of the interface between trafficking victims and the healthcare setting, over the last 10 years there has been a notable increase in training of health care professionals (HCPs) on human trafficking (HT) and its health implications. Many organizations have developed curricula and offered training in various clinical settings. However, methods and content of this education on trafficking vary widely, and there is little evaluation of the impact of the training. The goal of this study was to assess the gaps and strengths in HT education of HCPs in the US. This mixed-method study had two components. The first component consisted of structured interviews with experts in human trafficking HCP education. The second portion of the study involved an analysis of data from HCP calls to the National Human Trafficking Resource Center (NHTRC). The interviews captured trainer-specific data on types of HT training, duration and frequency, key content areas, presence of evaluation approaches and indicators, as well as an assessment of barriers and strengths in HT training for HCP. NHTRC call database analysis demonstrated increasing trends since 2008 in calls by HCPs. Overall findings revealed the need for standardization of HT training content to assure correct information, trauma-informed and patient-centered care, and consistent messaging for HCPs. Evaluation metrics for HT training need to be developed to demonstrate behavior change and impact on service delivery and patient-centered outcomes for HT victims, according to our proposed adapted Kirkpatrick's Pyramid model. HT training and evaluation would benefit from an agency or institution at the national level to provide consistency and standardization of HT training content as well as to guide a process that would develop metrics for evaluation and the building of an evidence base.

. Trafficking of membrane proteins to their correct endomembrane location is especially important to enable them to carry out their function. Although a considerable amount of knowledge about membrane protein trafficking in plants has been delivered by years of dedicated research, there are still significant...... gaps in our understanding of this process. Further knowledge of endomembrane trafficking is dependent on thorough characterization of the subcellular components that constitute the endomembrane system. Such studies are challenging for a number of reasons including the complexity of the plant...

The small GTPase Rab11 and its effectors control trafficking of recycling endosomes, receptor replenishment and the up-regulation of adhesion and adaptor molecules at the plasma membrane. Despite recent advances in the understanding of Rab11-regulated mechanisms, the final steps mediating docking and fusion of Rab11-positive vesicles at the plasma membrane are not fully understood. Munc13-4 is a docking factor proposed to regulate fusion through interactions with SNAREs. In hematopoietic cells, including neutrophils, Munc13-4 regulates exocytosis in a Rab27a-dependent manner, but its possible regulation of other GTPases has not been explored in detail. Here, we show that Munc13-4 binds to Rab11 and regulates the trafficking of Rab11-containing vesicles. Using a novel Time-resolved Fluorescence Resonance Energy Transfer (TR-FRET) assay, we demonstrate that Munc13-4 binds to Rab11a but not to dominant negative Rab11a. Immunoprecipitation analysis confirmed the specificity of the interaction between Munc13-4 and Rab11, and super-resolution microscopy studies support the interaction of endogenous Munc13-4 with Rab11 at the single molecule level in neutrophils. Vesicular dynamic analysis shows the common spatio-temporal distribution of Munc13-4 and Rab11, while expression of a calcium binding-deficient mutant of Munc13-4 significantly affected Rab11 trafficking. Munc13-4-deficient neutrophils showed normal endocytosis, but the trafficking, up-regulation, and retention of Rab11-positive vesicles at the plasma membrane was significantly impaired. This correlated with deficient NADPH oxidase activation at the plasma membrane in response to Rab11 interference. Our data demonstrate that Munc13-4 is a Rab11-binding partner that regulates the final steps of Rab11-positive vesicle docking at the plasma membrane. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.

Full Text Available Kaposi’s sarcoma associated herpesvirus (KSHV is etiologically associated with human endothelial cell hyperplastic Kaposi’s sarcoma and B-cell primary effusion lymphoma. KSHV infection of adherent endothelial and fibroblast cells are used as in vitro models for infection and KSHV enters these cells by host membrane bleb and actin mediated macropinocytosis or clathrin endocytosis pathways, respectively. Infection in endothelial and fibroblast cells is initiated by the interactions between multiple viral envelope glycoproteins and cell surface associated heparan sulfate (HS, integrins (α3β1, αVβ3 and αVβ5, and EphA2 receptor tyrosine kinase (EphA2R. This review summarizes the accumulated studies demonstrating that KSHV manipulates the host signal pathways to enter and traffic in the cytoplasm of the target cells, to deliver the viral genome into the nucleus, and initiate viral gene expression. KSHV interactions with the cell surface receptors is the key platform for the manipulations of host signal pathways which results in the simultaneous induction of FAK, Src, PI3-K, Rho-GTPase, ROS, Dia-2, PKC ζ, c-Cbl, CIB1, Crk, p130Cas and GEF-C3G signal and adaptor molecules that play critical roles in the modulation of membrane and actin dynamics, and in the various steps of the early stages of infection such as entry and trafficking towards the nucleus. The Endosomal Sorting Complexes Required for Transport (ESCRT proteins are also recruited to assist in viral entry and trafficking. In addition, KSHV interactions with the cell surface receptors also induces the host transcription factors NF-κB, ERK1/2, and Nrf2 early during infection to initiate and modulate viral and host gene expression. Nuclear delivery of the viral dsDNA genome is immediately followed by the host innate responses such as the DNA damage response (DDR, inflammasome and interferon responses. Overall, these studies form the initial framework for further studies of

LRRK2 affects vesicle trafficking, neurotransmitter extracellular level and membrane receptor localization.

Full Text Available The leucine-rich repeat kinase 2 (LRRK2 gene was found to play a role in the pathogenesis of both familial and sporadic Parkinson's disease (PD. LRRK2 encodes a large multi-domain protein that is expressed in different tissues. To date, the physiological and pathological functions of LRRK2 are not clearly defined. In this study we have explored the role of LRRK2 in controlling vesicle trafficking in different cellular or animal models and using various readouts. In neuronal cells, the presence of LRRK2(G2019S pathological mutant determines increased extracellular dopamine levels either under basal conditions or upon nicotine stimulation. Moreover, mutant LRRK2 affects the levels of dopamine receptor D1 on the membrane surface in neuronal cells or animal models. Ultrastructural analysis of PC12-derived cells expressing mutant LRRK2(G2019S shows an altered intracellular vesicle distribution. Taken together, our results point to the key role of LRRK2 to control vesicle trafficking in neuronal cells.

A theory for aftercare of human trafficking survivors for nursing practice in low resource settings.

Science.gov (United States)

Curran, R L; Naidoo, J R; Mchunu, G

2017-06-01

Research on aftercare for human trafficking survivors highlights the limited knowledge of the needs of survivors; the evaluation of current aftercare; and the process of recovery navigated by the survivor in aftercare (Oram et al., 2012; Locke, 2010; Hacker & Cohen, 2012). Furthermore there has been a transition in aftercare where the victim or survivor, who before was seen as a passive victim of circumstance of their life and in need of therapeutic intervention, is now seen as having an active role in their recovery, thus facilitating recovery (Hacker & Cohen, 2012). The need for a theory grounded in survivor's voices therefore motivated this grounded theory study underpinned by Freire's (1970) Pedagogy of the oppressed. The aim of the theory is to inform nursing care of human trafficking survivors in low resource settings. The findings elicit a theoretical model of the renewed self, and the conditions that facilitate this process in care of human trafficking survivors. The recommendations of this paper may improve the nursing care provided to human trafficking survivors and equip nurses and other health professionals with the knowledge and skills to promote the renewing of human trafficking survivors.

Todres, Jonathan

2017-01-01

There is growing recognition and evidence that health care professionals regularly encounter - though they may not identify - victims of human trafficking in a variety of health care settings. Identifying and responding appropriately to trafficking victims or survivors requires not only training in trauma-informed care but also consideration of the legal and ethical issues that arise when serving this vulnerable population. This essay examines three areas of law that are relevant to this case...

Endocytosis and Endosomal Trafficking in Plants.

Science.gov (United States)

Paez Valencia, Julio; Goodman, Kaija; Otegui, Marisa S

2016-04-29

Endocytosis and endosomal trafficking are essential processes in cells that control the dynamics and turnover of plasma membrane proteins, such as receptors, transporters, and cell wall biosynthetic enzymes. Plasma membrane proteins (cargo) are internalized by endocytosis through clathrin-dependent or clathrin-independent mechanism and delivered to early endosomes. From the endosomes, cargo proteins are recycled back to the plasma membrane via different pathways, which rely on small GTPases and the retromer complex. Proteins that are targeted for degradation through ubiquitination are sorted into endosomal vesicles by the ESCRT (endosomal sorting complex required for transport) machinery for degradation in the vacuole. Endocytic and endosomal trafficking regulates many cellular, developmental, and physiological processes, including cellular polarization, hormone transport, metal ion homeostasis, cytokinesis, pathogen responses, and development. In this review, we discuss the mechanisms that mediate the recognition and sorting of endocytic and endosomal cargos, the vesiculation processes that mediate their trafficking, and their connection to cellular and physiological responses in plants.

Powell, Clydette; Dickins, Kirsten; Stoklosa, Hanni

2017-01-01

ABSTRACT Some 21 million adults and children are labor-trafficked or sex-trafficked through force, fraud, or coercion. In recognition of the interface between trafficking victims and the healthcare setting, over the last 10 years there has been a notable increase in training of health care professionals (HCPs) on human trafficking (HT) and its health implications. Many organizations have developed curricula and offered training in various clinical settings. However, methods and content of this education on trafficking vary widely, and there is little evaluation of the impact of the training. The goal of this study was to assess the gaps and strengths in HT education of HCPs in the US. This mixed-method study had two components. The first component consisted of structured interviews with experts in human trafficking HCP education. The second portion of the study involved an analysis of data from HCP calls to the National Human Trafficking Resource Center (NHTRC). The interviews captured trainer-specific data on types of HT training, duration and frequency, key content areas, presence of evaluation approaches and indicators, as well as an assessment of barriers and strengths in HT training for HCP. NHTRC call database analysis demonstrated increasing trends since 2008 in calls by HCPs. Overall findings revealed the need for standardization of HT training content to assure correct information, trauma-informed and patient-centered care, and consistent messaging for HCPs. Evaluation metrics for HT training need to be developed to demonstrate behavior change and impact on service delivery and patient-centered outcomes for HT victims, according to our proposed adapted Kirkpatrick’s Pyramid model. HT training and evaluation would benefit from an agency or institution at the national level to provide consistency and standardization of HT training content as well as to guide a process that would develop metrics for evaluation and the building of an evidence base

2017-01-01

Human trafficking is a global problem and results in deleterious psychological, social, and physical effects on the lives of those who are trafficked; however, it is not clear how to best intervene with survivors. The purpose of this review was to synthesize the evidence of exit and postexit intervention programs for survivors of human trafficking to inform practice and research. Systematic review methods were used to search, select, and extract data from published and unpublished experimental, quasi-experimental, and preexperimental studies that assessed the effects of any exit or postexit interventions for victims of human trafficking. The authors searched eight databases, reviewed bibliographies, and conducted forward citation searches from relevant reports and prior reviews to find studies authored between 2005 and 2015. The search yielded six eligible studies that included 155 female and 6 male survivors from four countries. Interventions were diverse, with three using a trauma-informed approach. Authors measured a myriad of outcomes, including mental health, social network, community reintegration, and employment; however, the quality of most studies was poor. Evidence of effects of exit and postexit interventions is sparse, and much of the research is poorly designed and executed; however, the needs of trafficking survivors are complex and effective interventions are desperately needed. Implications for practice and research are discussed.

A Formidable Task: Reflections on obtaining legal empirical evidence on human trafficking in Canada

Directory of Open Access Journals (Sweden)

Hayli Millar

2017-04-01

Full Text Available This article explores the experiences, challenges and findings of two empirical research studies examining Canada’s legal efforts to combat human trafficking. The authors outline the methodologies of their respective studies and reflect on some of the difficulties they faced in obtaining empirical data on human trafficking court cases and legal proceedings. Ultimately, the authors found that Canadian trafficking case law developments are in their early stages with very few convictions, despite a growing number of police-reported charges. The authors assert it is difficult to assess the efficacy and effects of Canadian anti-trafficking laws and policies due to the institutional and political limitations to collecting legal data in this highly politicised subject area. They conclude with five recommendations to increase the transparency of Canada’s public claims about its anti-trafficking enforcement efforts and call for more empirically-based law reform.

Human Trafficking: The Role of Medicine in Interrupting the Cycle of Abuse and Violence.

Science.gov (United States)

Macias-Konstantopoulos, Wendy

2016-10-18

Human trafficking, a form of modern slavery, is an egregious violation of human rights with profound personal and public health implications. It includes forced labor and sexual exploitation of both U.S. and non-U.S. citizens and has been reported in all 50 states. Victims of human trafficking are currently among the most abused and disenfranchised persons in society, and they face a wide range of negative health outcomes resulting from their subjugation and exploitation. Medicine has an important role to play in mitigating the devastating effects of human trafficking on individuals and society. Victims are cared for in emergency departments, primary care offices, urgent care centers, community health clinics, and reproductive health clinics. In addition, they are unknowingly being treated in hospital inpatient units. Injuries and illnesses requiring medical attention thus represent unique windows of opportunity for trafficked persons to receive assistance from trusted health care professionals. With education and training, health care providers can recognize signs and symptoms of trafficking, provide trauma-informed care to this vulnerable population, and respond to exploited persons who are interested and ready to receive assistance. Multidisciplinary response protocols, research, and policy advocacy can enhance the impact of antitrafficking health care efforts to interrupt the cycle of abuse and violence for these victims.

Human Trafficking in Ethiopia: A Scoping Review to Identify Gaps in Service Delivery, Research, and Policy.

Beck, Dana C; Choi, Kristen R; Munro-Kramer, Michelle L; Lori, Jody R

2017-12-01

The purpose of this review is to integrate evidence on human trafficking in Ethiopia and identify gaps and recommendations for service delivery, research and training, and policy. A scoping literature review approach was used to systematically search nursing, medical, psychological, law, and international databases and synthesize information on a complex, understudied topic. The search yielded 826 articles, and 39 met the predetermined criteria for inclusion in the review. Trafficking in Ethiopia has occurred internally and externally in the form of adult and child labor and sex trafficking. There were also some reports of organ trafficking and other closely related human rights violations, such as child marriage, child soldiering, and exploitative intercountry adoption. Risk factors for trafficking included push factors (poverty, political instability, economic problems, and gender discrimination) and pull factors (demand for cheap labor). Trafficking was associated with poor health and economic outcomes for victims. Key recommendations for service delivery, research and training, and policy are identified, including establishing comprehensive services for survivor rehabilitation and reintegration, conducting quantitative health outcomes research, and reforming policy around migration and trafficking. Implementing the recommendations identified by this review will allow policy makers, researchers, and practitioners to take meaningful steps toward confronting human trafficking in Ethiopia.

Intensifying Insecurities: The impact of climate change on vulnerability to human trafficking in the Indian Sundarbans

Directory of Open Access Journals (Sweden)

Nicole Molinari

2017-04-01

Full Text Available Despite an enormous amount of attention paid to the factors that shape vulnerability to human trafficking, such as poverty and a lack of economic opportunity, the debate of evidence for what enables these factors to exist in the first place is relatively less explored. Presently, discussions of the relationship between climate change and human insecurity have been marginal to broader debates about vulnerability to trafficking. This paper argues that this signifies a gap in our understanding of the underlying drivers that push individuals and communities into situations where vulnerability to trafficking amplifies, but also that increase the pull of risky migration pathways and exploitative work situations. This paper proceeds by examining and problematising dominant conceptualisations of vulnerability in human trafficking and climate change discourses. Next, it presents a case study of the Sundarbans region of India to highlight how climate change impacts compound and exacerbate the same factors that shape vulnerability to human trafficking—including environmental degradation, loss of livelihood, destitution, and forced migration. Lastly, it argues for enhanced attention to climate change-related insecurity as evidence of vulnerability to trafficking and outlines what such insights can bring to anti-trafficking efforts.

Analysis of occludin trafficking, demonstrating continuous endocytosis, degradation, recycling and biosynthetic secretory trafficking.

Directory of Open Access Journals (Sweden)

Sarah J Fletcher

Full Text Available Tight junctions (TJs link adjacent cells and are critical for maintenance of apical-basolateral polarity in epithelial monolayers. The TJ protein occludin functions in disparate processes, including wound healing and Hepatitis C Virus infection. Little is known about steady-state occludin trafficking into and out of the plasma membrane. Therefore, we determined the mechanisms responsible for occludin turnover in confluent Madin-Darby canine kidney (MDCK epithelial monolayers. Using various biotin-based trafficking assays we observed continuous and rapid endocytosis of plasma membrane localised occludin (the majority internalised within 30 minutes. By 120 minutes a significant reduction in internalised occludin was observed. Inhibition of lysosomal function attenuated the reduction in occludin signal post-endocytosis and promoted co-localisation with the late endocytic system. Using a similar method we demonstrated that ∼20% of internalised occludin was transported back to the cell surface. Consistent with these findings, significant co-localisation between internalised occludin and recycling endosomal compartments was observed. We then quantified the extent to which occludin synthesis and transport to the plasma membrane contributes to plasma membrane occludin homeostasis, identifying inhibition of protein synthesis led to decreased plasma membrane localised occludin. Significant co-localisation between occludin and the biosynthetic secretory pathway was demonstrated. Thus, under steady-state conditions occludin undergoes turnover via a continuous cycle of endocytosis, recycling and degradation, with degradation compensated for by biosynthetic exocytic trafficking. We developed a mathematical model to describe the endocytosis, recycling and degradation of occludin, utilising experimental data to provide quantitative estimates for the rates of these processes.

Human trafficking and legalized prostitution in the Netherlands

Directory of Open Access Journals (Sweden)

Siegel Dina

2009-01-01

Full Text Available On 1 October 2000, the Netherlands became the first European country to legalize prostitution as a profession, with its rights and duties. On the other hand, this new Dutch law excluded those sex workers, who come from outside the EU. The majority of women working in the sex industry, who are considered illegal migrants in the Netherlands, had two choices: either leaving the country or disappearing into the illegal criminal circuit. For law enforcement and assistant services, it became extremely difficult to control the sector. In this paper, the consequences of the 'Brothel Law' are presented. What happens with illegal non-European sex workers in the Netherlands, how the problem of human trafficking is constructed in Dutch media and combated in the country, what could be learned from the 'Dutch case'? The paper aims to answer these questions and contribute to the general study on human trafficking and voluntary prostitution in Europe.

P2X7 receptors regulate multiple types of membrane trafficking responses and non-classical secretion pathways.

Science.gov (United States)

Qu, Yan; Dubyak, George R

2009-06-01

Activation of the P2X7 receptor (P2X7R) triggers a remarkably diverse array of membrane trafficking responses in leukocytes and epithelial cells. These responses result in altered profiles of cell surface lipid and protein composition that can modulate the direct interactions of P2X7R-expressing cells with other cell types in the circulation, in blood vessels, at epithelial barriers, or within sites of immune and inflammatory activation. Additionally, these responses can result in the release of bioactive proteins, lipids, and large membrane complexes into extracellular compartments for remote communication between P2X7R-expressing cells and other cells that amplify or modulate inflammation, immunity, and responses to tissue damages. This review will discuss P2X7R-mediated effects on membrane composition and trafficking in the plasma membrane (PM) and intracellular organelles, as well as actions of P2X7R in controlling various modes of non-classical secretion. It will review P2X7R regulation of: (1) phosphatidylserine distribution in the PM outer leaflet; (2) shedding of PM surface proteins; (3) release of PM-derived microvesicles or microparticles; (4) PM blebbing; (5) cell-cell fusion resulting in formation of multinucleate cells; (6) phagosome maturation and fusion with lysosomes; (7) permeability of endosomes with internalized pathogen-associated molecular patterns; (8) permeability/integrity of mitochondria; (9) exocytosis of secretory lysosomes; and (10) release of exosomes from multivesicular bodies.

Ungendering and Regendering Shelters for Survivors of Human Trafficking

Directory of Open Access Journals (Sweden)

Daphna Hacker

2015-02-01

Full Text Available This article is based on intensive fieldwork in the two Israeli shelters designated for victims of human trafficking and slavery. The shelters, one for women and one for men, are a refuge for survivors of sex trafficking; labor migrants subjected to severe exploitation by their employers; and asylum seekers who arrived in Israel after experiencing severe physical and emotional abuse at the hands of kidnappers and smugglers en route to Israel. The study included interviews with policy makers and professionals, and with women and men who resided at the shelters, as well as an analysis of the relevant legislation and official reports. The article explores the problematic gendered differentiations between the two shelters. Most significantly, while support for residents of the shelter for women is anchored by emotional and psychological rehabilitation, residents of the shelter for men do not receive any therapeutic support. At the same time, while staff in the shelter for men put significant effort into the reintegration of the men into the labor force, the women’s employment prospects receive less attention. Based on these and other findings, the article cautions against gender-biased rehabilitation services for victims of human trafficking and slavery, and calls for a gender-sensitive rehabilitation theory and practice.

Human trafficking, labor brokering, and mining in southern Africa: responding to a decentralized and hidden public health disaster.

Science.gov (United States)

Steele, Sarah

2013-01-01

Many southern African economies are dependent on the extractive industries. These industries rely on low-cost labor, often supplied by migrants, typically acquired through labor brokers. Very little attention has so far been paid to trafficking of men into extractive industries or its connection with trafficked women in the region's mining hubs. Recent reports suggest that labor-brokering practices foster human trafficking, both by exposing migrant men to lack of pay and exploitative conditions and by creating male migratory patterns that generate demand for sex workers and associated trafficking of women and girls. While trafficking in persons violates human rights, and thus remains a priority issue globally, there is little or no evidence of an effective political response to mine-related trafficking in southern Africa. This article concludes with recommendations for legal and policy interventions, as well as an enhanced public health response, which if implemented would help reduce human trafficking toward mining sites.

Structures of human folate receptors reveal biological trafficking states and diversity in folate and antifolate recognition.

Antifolates, folate analogs that inhibit vitamin B9 (folic acid)-using cellular enzymes, have been used over several decades for the treatment of cancer and inflammatory diseases. Cellular uptake of the antifolates in clinical use occurs primarily via widely expressed facilitative membrane transporters. More recently, human folate receptors (FRs), high affinity receptors that transport folate via endocytosis, have been proposed as targets for the specific delivery of new classes of antifolates or folate conjugates to tumors or sites of inflammation. The development of specific, FR-targeted antifolates would be accelerated if additional biophysical data, particularly structural models of the receptors, were available. Here we describe six distinct crystallographic models that provide insight into biological trafficking of FRs and distinct binding modes of folate and antifolates to these receptors. From comparison of the structures, we delineate discrete structural conformations representative of key stages in the endocytic trafficking of FRs and propose models for pH-dependent conformational changes. Additionally, we describe the molecular details of human FR in complex with three clinically prevalent antifolates, pemetrexed (also Alimta), aminopterin, and methotrexate. On the whole, our data form the basis for rapid design and implementation of unique, FR-targeted, folate-based drugs for the treatment of cancer and inflammatory diseases.

Queering the Support for Trafficked Persons: LGBTQ Communities and Human Trafficking in the Heartland

Directory of Open Access Journals (Sweden)

Corinne Schwarz

2015-02-01

Full Text Available Human trafficking justice centers on the “Three Ps” model of prevention, protection, and prosecution. While protection and prosecution efforts have been moderately successful, prevention remains elusive, as “upstream” structural fac-tors—class, gender, and sexuality inequalities—remain difficult to target. Individuals who are affected by these factors are not fully served within linear service frameworks. Based on a 12-month study in Kansas City, we find that service providers recognize the limitations of a “one-size-fits all” approach. Using a public health model, our research team con-ducted a public health surveillance, explored risk and protective factors, and facilitated organizational self-assessments of services. Our findings support a prevention approach that supports a survivor-centered model, which creates new, non-linear or queered avenues of agency and community for trafficking survivors. This model allows survivors to make use of services in moments of vulnerability and opt out of others in moments of resilience. Given the systematic cuts in funding that have affected service providers, this research contends that prevention is cheaper, more effective, and more ethical than relying on prosecutions to curb trafficking. Developing a model that fosters survivor empowerment is a key step toward individual justice and survivor resilience for vulnerable and marginalized populations.

Editorial: How is the money to combat human trafficking spent?

Mike Dottridge

2014-09-01

This edition of the Anti-Trafficking Review explores what happens to the money that is allocated by governments and private donors to stop human trafficking and to assist people who have been trafficked. It has been an honour to play the role of guest editor, though it has not been easy to steer a route between amazement (at the sums apparently involved, concern (at the lack of real insight into how money is allocated and spent and cynicism (at what appear to be rather modest achievements. It was challenging for potential authors to choose a method of analysing anti-trafficking spending. Should they simply describe what money is available and the drawbacks of the ways which donors make it available to organisations to use? Some authors take this descriptive approach. Should articles be about the efficiency and effectiveness of aid flows in general, in which case the shortcomings in anti-trafficking funding may mirror the generic flaws in aid flows? Only one author (Ucnikova has tackled this. Or, should studies focus on the way the purse strings are controlled by a small number of donors who appear poorly informed about the needs of trafficked persons or the factors that cause them to be trafficked? Several of the articles touch on this (e.g. those of Hoff and Nwogu. Early on, it became apparent to the editorial team that people working for large organisations with anti-trafficking programmes were wary of contributing articles on this topic. In this sense, although the Anti-Trafficking Review aims to promote public debate, we have not yet found the best way of opening up a debate about funding, for practitioners evidently fear that writing about their own sources of funding could result in the tap being turned off! So, it is mainly the Debate section that tackles the question of funding strategies. Even these contributions do not make assessments of the various actors involved (donors and the organisations they fund in as full and frank a way as is needed. The

2018-03-01

Human trafficking is a major public health concern that brings about deleterious psychological consequences and sequelae. Although a number of risk and protective factors for the health consequences of human trafficking victims have been identified, there is a dearth of information in the area of treatment. Specifically, we found no articles comparing the different components of prevailing trauma treatment strategies, and the potential usefulness of these strategies in the treatment of human trafficking victims. To this end, we compared and contrasted the different therapeutic treatments typically implemented with victims of trauma (including domestic violence victims and torture victims), and discussed how the different components of these treatments may or may not be helpful for human trafficking victims. We assessed the impact of these treatments on the psychological consequences of trauma and, in particular on posttraumatic stress disorder. We also assessed the potential usefulness of these treatments with co-occurring problems such as substance use, psychosis, dissociation, and other mood and anxiety disorders. On the basis of the prevailing research, we highlighted cognitive therapies as being preferred in addressing the needs of human trafficking victims. Mental health providers who work with human trafficking victims should become aware of and practiced in the use of cognitive therapeutic approaches in treating this population. Efficacy and effectiveness studies are needed to validate our recommendations.

Estradiol-induced estrogen receptor-alpha trafficking.

Science.gov (United States)

Bondar, Galyna; Kuo, John; Hamid, Naheed; Micevych, Paul

2009-12-02

Estradiol has rapid actions in the CNS that are mediated by membrane estrogen receptors (ERs) and activate cell signaling pathways through interaction with metabotropic glutamate receptors (mGluRs). Membrane-initiated estradiol signaling increases the free cytoplasmic calcium concentration ([Ca(2+)](i)) that stimulates the synthesis of neuroprogesterone in astrocytes. We used surface biotinylation to demonstrate that ERalpha has an extracellular portion. In addition to the full-length ERalpha [apparent molecular weight (MW), 66 kDa], surface biotinylation labeled an ERalpha-immunoreactive protein (MW, approximately 52 kDa) identified by both COOH- and NH(2)-directed antibodies. Estradiol treatment regulated membrane levels of both proteins in parallel: within 5 min, estradiol significantly increased membrane levels of the 66 and 52 kDa ERalpha. Internalization, a measure of membrane receptor activation, was also increased by estradiol with a similar time course. Continuous treatment with estradiol for 24-48 h reduced ERalpha levels, suggesting receptor downregulation. Estradiol also increased mGluR1a trafficking and internalization, consistent with the proposed ERalpha-mGluR1a interaction. Blocking ER with ICI 182,780 or mGluR1a with LY 367385 prevented ERalpha trafficking to and from the membrane. Estradiol-induced [Ca(2+)](i) flux was also significantly increased at the time of peak ERalpha activation/internalization. These results demonstrate that ERalpha is present in the membrane and has an extracellular portion. Furthermore, membrane levels and internalization of ERalpha are regulated by estradiol and mGluR1a ligands. The pattern of trafficking into and out of the membrane suggests that the changing concentration of estradiol during the estrous cycle regulates ERalpha to augment and then terminate membrane-initiated signaling.

Estradiol has rapid actions in the central nervous system, which are mediated by membrane estrogen receptors (ERs) and activate cell signaling pathways through interaction with metabotropic glutamate receptors (mGluRs). Membrane-initiated estradiol signaling increases the free cytoplasmic calcium concentration ([Ca2+]i) that stimulates the synthesis of neuroprogesterone in astrocytes. We used surface biotinylation to demonstrate that ERα has an extracellular portion. In addition to the full length ERα (apparent M.W. 66 kDa), surface biotinylation labeled an ERα-immunoreactive protein (M.W. ~ 52 kDa) identified by both COOH- and NH2-directed antibodies. Estradiol treatment regulated membrane levels of both proteins in parallel: within 5 min, estradiol significantly increased membrane levels of the 66 kDa and 52 kDa ERα. Internalization, a measure of membrane receptor activation, was also increased by estradiol with a similar time course. Continuous treatment with estradiol for 24–48 hr reduced ERα levels, suggesting receptor down-regulation. Estradiol also increased mGluR1a trafficking and internalization, consistent with the proposed ERα-mGluR1a interaction. Blocking ER with ICI 182,780 or mGluR1a with LY 367385 prevented ERα trafficking to and from the membrane. Estradiol-induced [Ca2+]i flux was also significantly increased at the time of peak ERα activation/internalization. These results demonstrate that ERα is present in the membrane and has an extracellular portion. Furthermore, membrane levels and internalization of ERα are regulated by estradiol and mGluR1a ligands. The pattern of trafficking into and out of the membrane suggests that the changing concentration of estradiol during the estrous cycle regulates ERα to augment and then terminate membrane-initiated signaling.

Full Text Available One of the most serious threats to the European Union is the organised crime. The EU is continuously adapting its response in order to best respond to the situation. Among different types of organised crime, human beings trafficking is one of the most seriously crimes worldwide, representing also a gross violation of human rights. Very often behind the human beings trafficking is the organised crime because is one of the most profitable criminal activities in the world. The numbers are very scary because it is estimated that the trafficked people to or within the EU are reaching several hundred thousands a year. The present study is intending to discover how the European Union intends to fight against the human beings trafficking, since there is a need to have a coherent action at the European level because of the criminals can easily operate across border.

Accurate data on the prevalence and psychological effects of human trafficking as well as treatment outcomes for survivors are essential for measuring the impact of interventions and generating better understanding of this phenomenon. However, such data are difficult to obtain. A legal mandate for health care professionals to report trafficking opens opportunities for advancing our work in the field of human trafficking but also poses risks to survivors seeking services. In this article, we provide an analysis of some critical ethical considerations for the development and implementation of a mandatory reporting policy and offer recommendations for the ethical implementation of such a policy. © 2017 American Medical Association.

Despite the multiple physical and psychological health consequences associated with human trafficking, there is little evidence-based guidance available for health providers on assessing and meeting the health needs of trafficked people. We aimed to review literature that provided guidance or research on care provision for people who had been trafficked. We conducted a systematic review and qualitative analysis of peer-reviewed and grey literature. Data sources included electronic databases, reference list screening, citation tracking, and expert recommendations. Documents were included if they reported on: 1) male or females (adults or children) who were currently or had previously been trafficked; 2) health interventions or service provision; 3) primary, secondary, tertiary or specialist post-trafficking services; and 4) World Bank high income countries. Two reviewers independently screened and quality appraised documents. Framework analysis was used to analyse extracted data. Forty-four documents were included, 19 of which reported findings of primary studies and nine of which exclusively addressed children. Evidence to inform the identification, referral and care of trafficked people is extremely limited. Within current literature on survivor identification, key indicators included signs of physical and sexual abuse, absence of documentation, and being accompanied by a controlling companion. Findings highlighted the importance of interviewing possible victims in private, using professional interpreters, and building trust. For provision of care, key themes included the importance of comprehensive needs assessments, adhering to principles of trauma-informed care, and cultural sensitivity. Further prominent themes were the necessity of multi-agency working strategies and well-defined referral pathways. Human trafficking survivors require healthcare that is trauma-informed and culturally sensitive to their particular needs. Coordination is needed between health

PIN-G – A novel reporter for imaging and defining the effects of trafficking signals in membrane proteins

2006-03-01

Full Text Available Abstract Background The identification of protein trafficking signals, and their interacting mechanisms, is a fundamental objective of modern biology. Unfortunately, the analysis of trafficking signals is complicated by their topography, hierarchical nature and regulation. Powerful strategies to test candidate motifs include their ability to direct simpler reporter proteins, to which they are fused, to the appropriate cellular compartment. However, present reporters are limited by their endogenous expression, paucity of cloning sites, and difficult detection in live cells. Results Consequently, we have engineered a mammalian expression vector encoding a novel trafficking reporter – pIN-G – consisting of a simple, type I integral protein bearing permissive intra/extracellular cloning sites, green fluorescent protein (GFP, cMyc and HA epitope tags. Fluorescence imaging, flow cytometry and biochemical assays of transfected HEK293 cells, confirm the size, topology and surface expression of PIN-G. Moreover, a pIN-G fusion construct, containing a Trans-Golgi Network (TGN targeting determinant, internalises rapidly from the cell surface and localises to the TGN. Additionally, another PIN-G fusion protein and its mutants reveal trafficking determinants in the cytoplasmic carboxy terminus of Kv1.4 voltage-gated potassium channels. Conclusion Together, these data indicate that pIN-G is a versatile, powerful, new reporter for analysing signals controlling membrane protein trafficking, surface expression and dynamics.

Autoantibodies against Muscarinic Type 3 Receptor in Sjögren's Syndrome Inhibit Aquaporin 5 Trafficking

Sjögren's syndrome (SjS) is a chronic autoimmune disease that mainly targets the salivary and lacrimal glands. It has been controversial whether anti-muscarinic type 3 receptor (α-M3R) autoantibodies in patients with SjS inhibit intracellular trafficking of aquaporin-5 (AQP5), water transport protein, leading to secretory dysfunction. To address this issue, GFP-tagged human AQP5 was overexpressed in human salivary gland cells (HSG-hAQP5) and monitored AQP5 trafficking to the plasma membrane following carbachol (CCh, M3R agonist) stimulation. AQP5 trafficking was indeed mediated by M3R stimulation, shown in partial blockage of trafficking by M3R-antagonist 4-DAMP. HSG-hAQP5 pre-incubated with SjS plasma for 24 hours significantly reduced AQP5 trafficking with CCh, compared with HSG-hAQP5 pre-incubated with healthy control (HC) plasma. This inhibition was confirmed by monoclonal α-M3R antibody and pre-absorbed plasma. Interestingly, HSG-hAQP5 pre-incubated with SjS plasma showed no change in cell volume, compared to the cells incubated with HC plasma showing shrinkage by twenty percent after CCh-stimulation. Our findings clearly indicate that binding of anti-M3R autoantibodies to the receptor, which was verified by immunoprecipitation, suppresses AQP5 trafficking to the membrane and contribute to impaired fluid secretion in SjS. Our current study urges further investigations of clinical associations between SjS symptoms, such as degree of secretory dysfunction, cognitive impairment, and/or bladder irritation, and different profiles (titers, isotypes, and/or specificity) of anti-M3R autoantibodies in individuals with SjS.

fertilization. Based on localization and mutant analyses, we conclude that CHXs modulate the ion balance, pH or both in micro-regions of endoplasmic reticulum, endosomes and prevacuolar compartment (PVC), and so influence membrane trafficking and signaling resulting in proper osmoregulation in guard cells and seed formation. We also demonstrated for the first time that AtKEA2 associates with chloroplasts, especially at the two poles of developing plastids. These results show that AtKEA1 and AtKEA2 transporters in specific microdomains of the inner envelope link local osmotic, ionic, and pH homeostasis to plastid division and thylakoid membrane formation. The first 3-D structure model of AtCHX was generated, and architecture-directed mutagenesis identified critical residues of the transport core giving insights to the transport mode of this family. Thus we have revealed for the first time crucial roles of an unknown K⁺/H⁺ transport family on plant growth (KEA), gas exchange, pollen cell wall, and different phases of reproduction (CHXs). The dynamic endomembrane of plant cells is integral to cytokinesis, cell expansion, defense, and cell wall formation, thus these studies are directly relevant to the mission of the Department of Energy and to a better understanding of determinants for enhancing plant biomass and plant tolerance to abiotic stress.

2018-01-01

This is the abstract that was submitted online with the paper: Despite the fact that many survivors of human trafficking have experienced complex trauma, there are no established interventions designed to specifically address these impacts. Leaders in the field of complex trauma have advocated for the need for somatic approaches to intervention. This paper presents STARS Experiential Group treatment, the first structured bodybased group intervention that has been designed to address complex trauma in survivors of human trafficking. Three pilot groups were run in residential settings with adolescent and adult survivors of sex trafficking. Two adaptations were utilized, with one focusing on application of expressive arts modalities and the other incorporating theater games. Qualitative results, using thematic analysis, identified several themes related to challenges and potential benefits of these groups. Potential benefits of the STARS groups were found in the areas of Interpersonal Relationships, Regulation, and Self/ Identity, with fourteen sub-themes further describing positive impacts. Challenges within these areas are explored, to inform the development of group interventions for trafficking survivors. The results of this paper suggest that experiential, somatically-oriented group treatment shows promise as an important element of holistic intervention with trafficking survivors.

From the endoplasmic reticulum to the plasma membrane: mechanisms of CFTR folding and trafficking.

Science.gov (United States)

Farinha, Carlos M; Canato, Sara

2017-01-01

CFTR biogenesis starts with its co-translational insertion into the membrane of endoplasmic reticulum and folding of the cytosolic domains, towards the acquisition of a fully folded compact native structure. Efficiency of this process is assessed by the ER quality control system that allows the exit of folded proteins but targets unfolded/misfolded CFTR to degradation. If allowed to leave the ER, CFTR is modified at the Golgi and reaches the post-Golgi compartments to be delivered to the plasma membrane where it functions as a cAMP- and phosphorylation-regulated chloride/bicarbonate channel. CFTR residence at the membrane is a balance of membrane delivery, endocytosis, and recycling. Several adaptors, motor, and scaffold proteins contribute to the regulation of CFTR stability and are involved in continuously assessing its structure through peripheral quality control systems. Regulation of CFTR biogenesis and traffic (and its dysregulation by mutations, such as the most common F508del) determine its overall activity and thus contribute to the fine modulation of chloride secretion and hydration of epithelial surfaces. This review covers old and recent knowledge on CFTR folding and trafficking from its synthesis to the regulation of its stability at the plasma membrane and highlights how several of these steps can be modulated to promote the rescue of mutant CFTR.

hERG trafficking inhibition in drug-induced lethal cardiac arrhythmia.

Science.gov (United States)

Nogawa, Hisashi; Kawai, Tomoyuki

2014-10-15

Acquired long QT syndrome induced by non-cardiovascular drugs can cause lethal cardiac arrhythmia called torsades de points and is a significant problem in drug development. The prolongation of QT interval and cardiac action potential duration are mainly due to reduced physiological function of the rapidly activating voltage-dependent potassium channels encoded by human ether-a-go-go-related gene (hERG). Structurally diverse groups of drugs are known to directly inhibit hERG channel conductance. Therefore, the ability of acute hERG inhibition is routinely assessed at the preclinical stages in pharmaceutical testing. Recent findings indicated that chronic treatment with various drugs not only inhibits hERG channels but also decreases hERG channel expression in the plasma membrane of cardiomyocytes, which has become another concern in safety pharmacology. The mechanisms involve the disruption of hERG trafficking to the surface membrane or the acceleration of hERG protein degradation. From this perspective, we present a brief overview of mechanisms of drug-induced trafficking inhibition and pathological regulation. Understanding of drug-induced hERG trafficking inhibition may provide new strategies for predicting drug-induced QT prolongation and lethal cardiac arrhythmia in pharmaceutical drug development.

2013-01-01

Background Previous studies have found high levels of symptoms of depression, anxiety, and post-traumatic stress disorder among women survivors of human trafficking. No previous research has described risk factors for diagnosed mental disorders in this population. Methods A historical cohort study of women survivors of trafficked women aged 18 and over who returned to Moldova and registered for assistance with the International Organisation for Migration (IOM). Women were approached by IOM social workers and, if they gave informed consented to participate in the study, interviewed by the research team. At 2–12 months post-return to Moldova, a psychiatrist assessed DSM-IV mental disorders blind to information about women’s pre-trafficking and post-trafficking experiences using the Structured Clinical Interview for DSM-IV (SCID). A backwards stepwise selection procedure was used to create a multivariable regression model of risk factors for DSM-IV mental disorder measured at an average of 6 months post-return. Results 120/176 (68%) eligible women participated. At an average of 6 months post-return, 54% met criteria for any DSM-IV mental disorder: 35.8% of women had PTSD (alone or co-morbid), 12.5% had depression without PTSD and 5.8% had another anxiety disorder. Multivariable regression analysis found that childhood sexual abuse (Adjusted Odds Ratio [AOR] 4.68, 95% CI 1.04-20.92), increased number of post-trafficking unmet needs (AOR 1.80; 95% CI 1.28-2.52) and post-trafficking social support (AOR 0.64; 95% CI 0.52-0.79) were independent risk factors for mental disorder, and that duration of trafficking showed a borderline association with mental disorder (AOR 1.12, 95% CI 0.98-1.29). Conclusions Assessment for mental disorders should be part of re-integration follow-up care for women survivors of human trafficking. Mental disorders at that time, most commonly PTSD and depression, are likely to be influenced by a range of predisposing, precipitating and

Highly specific detection of muscarinic M3 receptor, G protein interaction and intracellular trafficking in human detrusor using Proximity Ligation Assay (PLA).

Berndt-Paetz, Mandy; Herbst, Luise; Weimann, Annett; Gonsior, Andreas; Stolzenburg, Jens-Uwe; Neuhaus, Jochen

2018-05-01

Muscarinic acetylcholine receptors (mAChRs) regulate a number of important physiological functions. Alteration of mAChR expression or function has been associated in the etiology of several pathologies including functional bladder disorders (e.g bladder pain syndrome/interstitial cystitis - BPS/IC). In a previous study we found specific mAChR expression patterns associated with BPS/IC, while correlation between protein and gene expression was lacking. Posttranslational regulatory mechanisms, e.g. altered intracellular receptor trafficking, could explain those differences. In addition, alternative G protein (GP) coupling could add to the pathophysiology via modulation of muscarinic signaling. In our proof-of-principle study, we addressed these questions in situ. We established PLA in combination with confocal laserscanning microscopy (CLSM) and 3D object reconstruction for highly specific detection and analysis of muscarinic 3 receptors (M3), G protein (GP) coupling and intracellular trafficking in human detrusor samples. Paraffin sections of formalin-fixed bladder tissue (FFPE) of BPS/IC patients receiving transurethral biopsy were examined by Cy3-PLA for M3 expression, coupling of M3 to GPs (G αq/11 , G αs , G αi ) and interaction of M3 with endocytic regulator proteins. Membranes were labeled with wheat germ agglutinin-Alexa Fluor ® 488, nuclei were stained with DAPI. Object density and co-localization were analyzed in 3D-reconstruction of high resolution confocal z-stacks. Confocal image stack processing resulted in well demarcated objects. Calculated receptor densities correlated significantly with existing confocal expression data, while significantly improved specificity of M3 detection by PLA was verified using bladder tissue samples from transgenic mice. 50-60% of the M3 receptor complexes were plasma membrane associated in human bladder detrusor. Application of PLA for M3 and GPs allowed visualization of M3-GP interactions and revealed individual GP

The trafficking of persons is one of the most egregious violations of human rights in modern society. Given the disproportionate effects across demographic categories of age and gender, as well as concentrated impacts within the developing world, there is a strong need for research and literature on program effectiveness and appropriate aftercare efforts for those persons whose lives and livelihoods have been impacted by trafficking. The purpose of this article is to provide a scoping review of what is known about effectively helping survivors of human trafficking experiencing lack of economic opportunity and the implications for practice and future research regarding the absence of literature. From over 14,000 initial search results, this article focuses on those initiatives (N = 16) that support economic development of the individual or family after being trafficked. Implications arising from the review for trafficking policy, areas for further research, and implications for practitioners are highlighted and discussed.

Full Text Available As is the case in many countries, in Ethiopia human trafficking causes multi-dimensional harmful consequences on individuals. With a view to addressing the problem, in 2012 Ethiopia acceded to the Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children, supplementing the United Nations Convention against Transnational Organized Crime. For the purpose of translating the requirements of the UN Trafficking Protocol into reality, the government has taken various steps including legislative measures. Proclamation No. 909/2015 (Prevention and Suppression of Trafficking in Persons and Smuggling of Migrants Proclamation is the most recent law adopted to deal with smuggling of migrants and human trafficking. The Proclamation comprises four key aspects: criminalization and prosecution; prevention; protection, rehabilitation and compensation; and cooperation. This article critically examines whether the criminalization and prosecution aspect of the Proclamation complies with international standards.

Enhancements in the national transplant law to prohibit commercial transplants in India have curbed the trade. Yet, the human rights abuse of human trafficking for organ removal (HTOR) continues in various transplant centers throughout India. Beginning in September 2010 until May 2012, in-depth interviews were conducted with 103 victims of HTOR in India in which victims described their experiences of a commercial kidney removal in compelling detail. Victims were located in Tamil Nadu, and reference is made to the broader study that included 50 additional victims in small towns and villages in West Bengal and Karnataka. Fourteen cases (14%) in Tamil Nadu and an additional 20 cases (40%) from West Bengal and Karnataka occurred between 2009 to May 2012. The cases in Tamil Nadu ranged in age from 19 to 55 years, with an average age of 33 years in Erode and 36 years in Chennai. Fifty-seven percent of the victims in Erode are female, and 87% of the victims in Chennai are female. Twelve percent of the individuals were widowed or abandoned, 79% were married, and 91% were parents with an average of two kids. Of those interviewed, 28% had no formal education, 19% had some primary schooling, 22% had some secondary schooling, and no individuals reported schooling above high school. All victims interviewed lived in abject poverty with monthly income levels well below the national average. The majority of victims reported long lasting health, economic, social, and psychological consequences. No matter the reason expressed for an organ sale, all victims reported that they would not have agreed to the organ removal if their economic circumstances were not so dire. One hundred percent of the victims interviewed expressed that they need assistance to cope with these consequences. Human trafficking for an organ removal continues in private transplant centers throughout India, service to foreign patients is ongoing, and victims' consequences are long lasting.

Physiological Roles of Plant Post-Golgi Transport Pathways in Membrane Trafficking.

Science.gov (United States)

Uemura, Tomohiro

2016-10-01

Membrane trafficking is the fundamental system through which proteins are sorted to their correct destinations in eukaryotic cells. Key regulators of this system include RAB GTPases and soluble N-ethylmaleimide sensitive factor attachment protein receptors (SNAREs). Interestingly, the numbers of RAB GTPases and SNAREs involved in post-Golgi transport pathways in plant cells are larger than those in animal and yeast cells, suggesting that plants have evolved unique and complex post-Golgi transport pathways. The trans-Golgi network (TGN) is an important organelle that acts as a sorting station in the post-Golgi transport pathways of plant cells. The TGN also functions as the early endosome, which is the first compartment to receive endocytosed proteins. Several endocytosed proteins on the plasma membrane (PM) are initially targeted to the TGN/EE, then recycled back to the PM or transported to the vacuole for degradation. The recycling and degradation of the PM localized proteins is essential for the development and environmental responses in plant. The present review describes the post-Golgi transport pathways that show unique physiological functions in plants. © The Author 2016.

Human trafficking education for nurse practitioners: Integration into standard curriculum.

Science.gov (United States)

Lutz, Rebecca M

2018-02-01

Human trafficking is a crime resulting in serious negative health outcomes for the victims. To provide optimal care, thus improving health outcomes, healthcare providers must be able to identify victims as they seek care for acute and chronic physical illness, communicable diseases, sexually transmitted infections, and mental health disorders (Lederer and Wetzel, 2014; Oram et al., 2012). Unfortunately, healthcare providers lack appropriate knowledge of clues that would lead to victim identification. This may result in a failure to identify victims (Beck et al., 2015; Ross et al., 2015; Konstantopoulos et al., 2013; Chisolm-Straker et al., 2012). Increasing the number of healthcare providers able to identify, treat, and refer victims of trafficking for further care is imperative. The study evaluated the knowledge level of student nurse practitioners enrolled in an adult, family, or pediatric clinical course. Knowledge domains included the definitions, laws, prevalence, identification, treatment, and community and social service resources. The study was designed as a non-probability sampling of adult, family, and pediatric nurse practitioner students (n=73). Participants included students enrolled in the Adult & Older Adult I or the Primary Care of the Child & Adolescent I course at a large public university. The study was designed as a one hour educational intervention intended for presentation in a lecture-style format. The educational intervention included a PowerPoint lecture and embedded videos. The pre-survey, designed as a paper survey, contained a demographic section followed by six survey questions covering the six domains of interest. Following the intervention, participants completed the post-survey prior to leaving the classroom. Pre-survey results pinpointed knowledge gaps across all six domains under investigation. Post-survey results revealed an increase in knowledge across all six domains of interest. The educational intervention increased knowledge

As the primary contact in the health care system, nurses can play a role in combating this crime and assisting the victims. Assessment for abuse, neglect, trauma, recurrent sexually transmitted infections (STIs) and fear of a controlling partner is critical. Following up on "red flags" and understanding methods of safe questioning can make the difference between slavery and recovery for victims. Nurses must also know the professional referrals in their areas once a potential victim has been identified. This may be a very dangerous undertaking and must be handled by experienced personnel. Referrals to forensic nurses or physicians, domestic violence professionals or law enforcement may be indicated. Initially, a nurse may want to consult with the agency social worker for guidance. Human trafficking is a human rights crime. Unfortunately, it is more prevalent in all types of communities than most people suspect. Nurses can be heroes to the victims through understanding of this crime and vigilance in the assessment and care of all people they encounter in their practices.

Human trafficking for labour exploitation:
Interpreting the crime

Directory of Open Access Journals (Sweden)

Jill E.B. Coster van Voorhout

2007-12-01

Full Text Available The definition of human trafficking for labour exploitation, as follows from the European Council Framework Decision, proves to be unclear. Literal interpretation does not suffice, because it does not clarify all elements of what is deemed to be criminal behaviour, and hermeneutical interpretation also falls short discouraging the aim of this legislation, namely harmonisation. Hence, another solution is required. This article does so by firstly challenging assumptions about human trafficking for labour exploitation that are generally pertinent, but nonetheless untrue. This accurate appraisal of the crime’s nature is followed by a synopsis of national legislation and adjudication in three Member States, so as to also focus on these actualities regarding the crime that are commonly not conceived. This article examines two countries that have implemented the Framework Decision, namely Belgium and the Netherlands, and one that has not yet done so, the United Kingdom. Thereafter remaining unexplained elements of the Framework Decision’s definition are interpreted with use of international, pan-European and European legislation and adjudication. Based upon all this, a suggested interpretation of the Framework Decision’s definition is provided so as to overcome all identified difficulties with it.

2016-02-16

Parkinson's disease (PD) is an age-related neurodegenerative disorder characterized by the accumulation of protein aggregates comprised of α-synuclein (α-syn). A major barrier in treatment discovery for PD is the lack of identifiable therapeutic pathways capable of reducing aggregates in human neuronal model systems. Mutations in key components of protein trafficking and cellular degradation machinery represent important risk factors for PD; however, their precise role in disease progression and interaction with α-syn remains unclear. Here, we find that α-syn accumulation reduced lysosomal degradation capacity in human midbrain dopamine models of synucleinopathies through disrupting hydrolase trafficking. Accumulation of α-syn at the cell body resulted in aberrant association with cis-Golgi-tethering factor GM130 and disrupted the endoplasmic reticulum-Golgi localization of rab1a, a key mediator of vesicular transport. Overexpression of rab1a restored Golgi structure, improved hydrolase trafficking and activity, and reduced pathological α-syn in patient neurons. Our work suggests that enhancement of lysosomal hydrolase trafficking may prove beneficial in synucleinopathies and indicates that human midbrain disease models may be useful for identifying critical therapeutic pathways in PD and related disorders.

Le, Nguyen-Quoc-Khanh; Ho, Quang-Thai; Ou, Yu-Yen

2018-06-13

Deep learning has been increasingly used to solve a number of problems with state-of-the-art performance in a wide variety of fields. In biology, deep learning can be applied to reduce feature extraction time and achieve high levels of performance. In our present work, we apply deep learning via two-dimensional convolutional neural networks and position-specific scoring matrices to classify Rab protein molecules, which are main regulators in membrane trafficking for transferring proteins and other macromolecules throughout the cell. The functional loss of specific Rab molecular functions has been implicated in a variety of human diseases, e.g., choroideremia, intellectual disabilities, cancer. Therefore, creating a precise model for classifying Rabs is crucial in helping biologists understand the molecular functions of Rabs and design drug targets according to such specific human disease information. We constructed a robust deep neural network for classifying Rabs that achieved an accuracy of 99%, 99.5%, 96.3%, and 97.6% for each of four specific molecular functions. Our approach demonstrates superior performance to traditional artificial neural networks. Therefore, from our proposed study, we provide both an effective tool for classifying Rab proteins and a basis for further research that can improve the performance of biological modeling using deep neural networks.

Laura Cordisco Tsai

2017-05-01

Full Text Available Survivors of human trafficking often experience considerable financial difficulties upon exiting human trafficking, including pressure to provide financially for their families, challenges securing employment, lack of savings, and familial debt. Few evaluations have been conducted of reintegration support interventions addressing financial vulnerability among trafficking survivors. In this article, we present findings from a participatory assessment of the BARUG program, a matched savings and financial capability program for survivors of human trafficking and their family members in the Philippines. Photovoice was used to understand the experiences of two cohorts of BARUG participants. Survivors collaborated with research team members in conducting thematic analysis of transcripts from the photovoice sessions. Themes included: the positive emotional impact of financial wellness, overcoming the challenges of saving, applying financial management skills in daily decision making, developing a habit of savings, building a future-oriented mindset, receiving guidance and enlightenment, the learning process, and the change process. Findings reinforce the importance of interventions to support trafficked persons and their family members in getting out of debt and accumulating emergency savings, while also providing emotional support to survivors in coping with family financial pressures. The study also highlights the value of using participatory research methods to understand the experiences of trafficked persons. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs1702116

Scavenger receptor Class B type 1 (SR-B1) is a lipid transporter and sensor. In intestinal epithelial cells, SR-B1-dependent lipid sensing is associated with SR-B1 recruitment in raft-like/ detergent-resistant membrane domains and interaction of its C-terminal transmembrane domain with plasma membrane cholesterol. To clarify the initiating events occurring during lipid sensing by SR-B1, we analyzed cholesterol trafficking and raft-like domain composition in intestinal epithelial cells expressing wild-type SR-B1 or the mutated form SR-B1-Q445A, defective in membrane cholesterol binding and signal initiation. These features of SR-B1 were found to influence both apical cholesterol efflux and intracellular cholesterol trafficking from plasma membrane to lipid droplets, and the lipid composition of raft-like domains. Lipidomic analysis revealed likely participation of d18:0/16:0 sphingomyelin and 16:0/0:0 lysophosphatidylethanolamine in lipid sensing by SR-B1. Proteomic analysis identified proteins, whose abundance changed in raft-like domains during lipid sensing, and these included molecules linked to lipid raft dynamics and signal transduction. These findings provide new insights into the role of SR-B1 in cellular cholesterol homeostasis and suggest molecular links between SR-B1-dependent lipid sensing and cell cholesterol and lipid droplet dynamics.

Female sex trafficking is a pressing concern. In this article, we provide a comprehensive overview of relevant issues regarding the concept of female sex trafficking and research in the field of human trafficking, drawing on a variety of disciplines, including economics, gender and sexuality studies, psychology, sociology, law, and social work. We discuss the debates surrounding the definition of human trafficking, compare and contrast it with human smuggling, and outline connections between female sex trafficking and the issue of sex work and prostitution. We further discuss the history and current estimations of female sex trafficking. We then outline the main actors in female sex trafficking, including trafficked persons, traffickers, clients, and service providers, and we overview the trafficking process from recruitment to identification, recovery, and (re)integration. Finally, we conclude with recommendations for future research that tie together the concepts of vulnerability, exploitation, and long-term recovery and (re)integration.

Novel role for proteinase-activated receptor 2 (PAR2) in membrane trafficking of proteinase-activated receptor 4 (PAR4).

Proteinase-activated receptors 4 (PAR(4)) is a class A G protein-coupled receptor (GPCR) recognized through the ability of serine proteases such as thrombin and trypsin to mediate receptor activation. Due to the irreversible nature of activation, a fresh supply of receptor is required to be mobilized to the cell surface for responsiveness to agonist to be sustained. Unlike other PAR subtypes, the mechanisms regulating receptor trafficking of PAR(4) remain unknown. Here, we report novel features of the intracellular trafficking of PAR(4) to the plasma membrane. PAR(4) was poorly expressed at the plasma membrane and largely retained in the endoplasmic reticulum (ER) in a complex with the COPI protein subunit β-COP1. Analysis of the PAR(4) protein sequence identified an arginine-based (RXR) ER retention sequence located within intracellular loop-2 (R(183)AR → A(183)AA), mutation of which allowed efficient membrane delivery of PAR(4). Interestingly, co-expression with PAR(2) facilitated plasma membrane delivery of PAR(4), an effect produced through disruption of β-COP1 binding and facilitation of interaction with the chaperone protein 14-3-3ζ. Intermolecular FRET studies confirmed heterodimerization between PAR(2) and PAR(4). PAR(2) also enhanced glycosylation of PAR(4) and activation of PAR(4) signaling. Our results identify a novel regulatory role for PAR(2) in the anterograde traffic of PAR(4). PAR(2) was shown to both facilitate and abrogate protein interactions with PAR(4), impacting upon receptor localization and cell signal transduction. This work is likely to impact markedly upon the understanding of the receptor pharmacology of PAR(4) in normal physiology and disease.

Who’s Who at the Border? A rights-based approach to identifying human trafficking at international borders

Directory of Open Access Journals (Sweden)

Marika McAdam

2013-09-01

Full Text Available International borders are widely touted as bastions in the fight against trafficking in persons. This article acknowledges the important role border officials play in preventing human trafficking, but calls for expectations to be tempered by deference to the conceptual complexity of cross-border trafficking and the migration processes involved. The fact that many trafficked victims begin their journeys as irregular or smuggled migrants highlights the challenge posed to border officials in identifying trafficked persons among the people they encounter. Indicators of trafficking generally relate to the exploitation phase, leaving border officials with little guidance as to how persons vulnerable to trafficking can be accurately identified before any exploitation has occurred. Ultimately, this paper advocates a pragmatic rights-based approach in designating anti-trafficking functions to border officials. A rights-based approach to border control acknowledges the core work of border officials as being to uphold border integrity, while ensuring that their performance of this role does not jeopardise the rights of those they intercept nor result in missed opportunities for specialists to identify trafficked persons and other vulnerable people among them.

A fluorescent glycolipid-binding peptide probe traces cholesterol dependent microdomain-derived trafficking pathways.

Directory of Open Access Journals (Sweden)

Steffen Steinert

Full Text Available BACKGROUND: The uptake and intracellular trafficking of sphingolipids, which self-associate into plasma membrane microdomains, is associated with many pathological conditions, including viral and toxin infection, lipid storage disease, and neurodegenerative disease. However, the means available to label the trafficking pathways of sphingolipids in live cells are extremely limited. In order to address this problem, we have developed an exogenous, non-toxic probe consisting of a 25-amino acid sphingolipid binding domain, the SBD, derived from the amyloid peptide Abeta, and conjugated by a neutral linker with an organic fluorophore. The current work presents the characterization of the sphingolipid binding and live cell trafficking of this novel probe, the SBD peptide. SBD was the name given to a motif originally recognized by Fantini et al in a number of glycolipid-associated proteins, and was proposed to interact with sphingolipids in membrane microdomains. METHODOLOGY/PRINCIPAL FINDINGS: In accordance with Fantini's model, optimal SBD binding to membranes depends on the presence of sphingolipids and cholesterol. In synthetic membrane binding assays, SBD interacts preferentially with raft-like lipid mixtures containing sphingomyelin, cholesterol, and complex gangliosides in a pH-dependent manner, but is less glycolipid-specific than Cholera toxin B (CtxB. Using quantitative time-course colocalization in live cells, we show that the uptake and intracellular trafficking route of SBD is unlike that of either the non-raft marker Transferrin or the raft markers CtxB and Flotillin2-GFP. However, SBD traverses an endolysosomal route that partially intersects with raft-associated pathways, with a major portion being diverted at a late time point to rab11-positive recycling endosomes. Trafficking of SBD to acidified compartments is strongly disrupted by cholesterol perturbations, consistent with the regulation of sphingolipid trafficking by cholesterol

PIST regulates the intracellular trafficking and plasma membrane expression of Cadherin 23

Directory of Open Access Journals (Sweden)

Oshima Kazuo

2010-10-01

Full Text Available Abstract Background The atypical cadherin protein cadherin 23 (CDH23 is crucial for proper function of retinal photoreceptors and inner ear hair cells. As we obtain more and more information about the specific roles of cadherin 23 in photoreceptors and hair cells, the regulatory mechanisms responsible for the transport of this protein to the plasma membrane are largely unknown. Results PIST, a Golgi-associated, PDZ domain-containing protein, interacted with cadherin 23 via the PDZ domain of PIST and the C-terminal PDZ domain-binding interface (PBI of cadherin 23. By binding to cadherin 23, PIST retained cadherin 23 in the trans-Golgi network of cultured cells. The retention was released when either of the two known cadherin 23-binding proteins MAGI-1 and harmonin was co-expressed. Similar to MAGI-1 and harmonin, PIST was detected in mouse inner ear sensory hair cells. Conclusions PIST binds cadherin 23 via its PDZ domain and retains cadherin 23 in trans-Golgi network. MAGI-1 and harmonin can compete with PIST for binding cadherin 23 and release cadherin 23 from PIST's retention. Our finding suggests that PIST, MAGI-1 and harmonin collaborate in intracellular trafficking of cadherin 23 and regulate the plasma membrane expression of cadherin 23.

Synaptic Control of Secretory Trafficking in Dendrites

Directory of Open Access Journals (Sweden)

Cyril Hanus

2014-06-01

Full Text Available Localized signaling in neuronal dendrites requires tight spatial control of membrane composition. Upon initial synthesis, nascent secretory cargo in dendrites exits the endoplasmic reticulum (ER from local zones of ER complexity that are spatially coupled to post-ER compartments. Although newly synthesized membrane proteins can be processed locally, the mechanisms that control the spatial range of secretory cargo transport in dendritic segments are unknown. Here, we monitored the dynamics of nascent membrane proteins in dendritic post-ER compartments under regimes of low or increased neuronal activity. In response to activity blockade, post-ER carriers are highly mobile and are transported over long distances. Conversely, increasing synaptic activity dramatically restricts the spatial scale of post-ER trafficking along dendrites. This activity-induced confinement of secretory cargo requires site-specific phosphorylation of the kinesin motor KIF17 by Ca2+/calmodulin-dependent protein kinases (CaMK. Thus, the length scales of early secretory trafficking in dendrites are tuned by activity-dependent regulation of microtubule-dependent transport.

Full Text Available Human trafficking is a violation of the human rights. One of the campaign to fight against this crime takes the form of a digital campaign that aired on television and internet.   This study discusses the narrative structure of human trafficking campaign video from non-profit organization MTV Exit in 2012. This video campaign combines art collage and graphic art in its narrative structure. Nonverbal visual elements displayed in the form of a digital photo collage with animated illustrations setting. We consider this video campaign quite interesting as it is visually inform the public about the importance of safe migration through the visual signs in the narrative structure. This study analyzes qualitatively the relation of nonverbal visual signs in the narrative collage and illustration. Denotative and connotative analysis with structural semiotics approach is needed to understand the meaning of visual signs in the context of humans as cultural beings in their communities. This study is expected to be a model example of visual communication campaigns that can foster public awareness of the issue of human trafficking, especially for young women and children as young generation.

Outer membrane vesicles (OMVs) are important tools in bacterial virulence but their role in the pathogenesis of infections caused by enterohemorrhagic Escherichia coli (EHEC) O157, the leading cause of life-threatening hemolytic uremic syndrome, is poorly understood. Using proteomics, electron and confocal laser scanning microscopy, immunoblotting, and bioassays, we investigated OMVs secreted by EHEC O157 clinical isolates for virulence factors cargoes, interactions with pathogenetically relevant human cells, and mechanisms of cell injury. We demonstrate that O157 OMVs carry a cocktail of key virulence factors of EHEC O157 including Shiga toxin 2a (Stx2a), cytolethal distending toxin V (CdtV), EHEC hemolysin, and flagellin. The toxins are internalized by cells via dynamin-dependent endocytosis of OMVs and differentially separate from vesicles during intracellular trafficking. Stx2a and CdtV-B, the DNase-like CdtV subunit, separate from OMVs in early endosomes. Stx2a is trafficked, in association with its receptor globotriaosylceramide within detergent-resistant membranes, to the Golgi complex and the endoplasmic reticulum from where the catalytic Stx2a A1 fragment is translocated to the cytosol. CdtV-B is, after its retrograde transport to the endoplasmic reticulum, translocated to the nucleus to reach DNA. CdtV-A and CdtV-C subunits remain OMV-associated and are sorted with OMVs to lysosomes. EHEC hemolysin separates from OMVs in lysosomes and targets mitochondria. The OMV-delivered CdtV-B causes cellular DNA damage, which activates DNA damage responses leading to G2 cell cycle arrest. The arrested cells ultimately die of apoptosis induced by Stx2a and CdtV via caspase-9 activation. By demonstrating that naturally secreted EHEC O157 OMVs carry and deliver into cells a cocktail of biologically active virulence factors, thereby causing cell death, and by performing first comprehensive analysis of intracellular trafficking of OMVs and OMV-delivered virulence factors

Highlights: {yields} Impaired trafficking of kAE1 causes distal renal tubular acidosis (dRTA). {yields} The interaction between kAE1 and kinesin family member 3B (KIF3B) is reported. {yields} The co-localization between kAE and KIF3B was detected in human kidney tissues. {yields} A marked reduction of kAE1 on the cell membrane was observed when KIF3B was knockdown. {yields} KFI3B plays an important role in trafficking of kAE1 to the plasma membrane. -- Abstract: Impaired trafficking of human kidney anion exchanger 1 (kAE1) to the basolateral membrane of {alpha}-intercalated cells of the kidney collecting duct leads to the defect of the Cl{sup -}/HCO{sub 3}{sup -} exchange and the failure of proton (H{sup +}) secretion at the apical membrane of these cells, causing distal renal tubular acidosis (dRTA). In the sorting process, kAE1 interacts with AP-1 mu1A, a subunit of AP-1A adaptor complex. However, it is not known whether kAE1 interacts with motor proteins in its trafficking process to the plasma membrane or not. We report here that kAE1 interacts with kinesin family member 3B (KIF3B) in kidney cells and a dileucine motif at the carboxyl terminus of kAE1 contributes to this interaction. We have also demonstrated that kAE1 co-localizes with KIF3B in human kidney tissues and the suppression of endogenous KIF3B in HEK293T cells by small interfering RNA (siRNA) decreases membrane localization of kAE1 but increases its intracellular accumulation. All results suggest that KIF3B is involved in the trafficking of kAE1 to the plasma membrane of human kidney {alpha}-intercalated cells.

Human liver cell trafficking mutants: characterization and whole exome sequencing.

Full Text Available The HuH7 liver cell mutant Trf1 is defective in membrane trafficking and is complemented by the casein kinase 2α subunit CK2α''. Here we identify characteristic morphologies, trafficking and mutational changes in six additional HuH7 mutants Trf2-Trf7. Trf1 cells were previously shown to be severely defective in gap junction functions. Using a Lucifer yellow transfer assay, remarkable attenuation of gap junction communication was revealed in each of the mutants Trf2-Trf7. Electron microscopy and light microscopy of thiamine pyrophosphatase showed that several mutants exhibited fragmented Golgi apparatus cisternae compared to parental HuH7 cells. Intracellular trafficking was investigated using assays of transferrin endocytosis and recycling and VSV G secretion. Surface binding of transferrin was reduced in all six Trf2-Trf7 mutants, which generally correlated with the degree of reduced expression of the transferrin receptor at the cell surface. The mutants displayed the same transferrin influx rates as HuH7, and for efflux rate, only Trf6 differed, having a slower transferrin efflux rate than HuH7. The kinetics of VSV G transport along the exocytic pathway were altered in Trf2 and Trf5 mutants. Genetic changes unique to particular Trf mutants were identified by exome sequencing, and one was investigated in depth. The novel mutation Ile34Phe in the GTPase RAB22A was identified in Trf4. RNA interference knockdown of RAB22A or overexpression of RAB22AI34F in HuH7 cells caused phenotypic changes characteristic of the Trf4 mutant. In addition, the Ile34Phe mutation reduced both guanine nucleotide binding and hydrolysis activities of RAB22A. Thus, the RAB22A Ile34Phe mutation appears to contribute to the Trf4 mutant phenotype.

Modern slavery is less overt than historical state-sanctioned slavery because psychological abuse is typically used to recruit and then control victims. The recent UK Draft Modern Slavery Bill, and current UK government anti-slavery strategy relies heavily on a shared understanding and public cooperation to tackle this crime. Yet, UK research investigating public understanding of modern slavery is elusive. We report community survey data from 682 residents of the Midlands of England, where modern slavery is known to occur, concerning their understanding of nonphysical coercion and human trafficking (one particular form of modern slavery). Analysis of quantitative data and themed categorization of qualitative data revealed a mismatch between theoretical frameworks and understanding of psychological coercion, and misconceptions concerning the nature of human trafficking. Many respondents did not understand psychological coercion, believed that human trafficking did not affect them, and confused trafficking with immigration. The public are one of the most influential interest groups, but only if well informed and motivated towards positive action. Our findings suggest the need for strategically targeted public knowledge exchange concerning this crime. PMID:27149330

The prototypic betaherpesvirus human cytomegalovirus (CMV) establishes life-long persistence within its human host. While benign in healthy individuals, CMV poses a significant threat to the immune compromised, including transplant recipients and neonates. The CMV glycoprotein complex gH/gL/gO mediates infection of fibroblasts, and together with the gH/gL/UL128/130/131 a pentameric complex permits infection of epithelial, endothethial, and myeloid cells. Given the central role of the gH/gL complex during infection, we were interested in studying cellular trafficking of the gH/gL complex through generation of human cells that stably express gH and gL. When expressed alone, CMV gH and gL were degraded through the ER-associated degradation (ERAD) pathway. However, co-expression of these proteins stabilized the polypeptides and enhanced their cell-surface expression. To further define regulatory factors involved in gH/gL trafficking, a CMV gH chimera in which the gH transmembrane and cytoplasmic tail were replaced with that of human CD4 protein permitted cell surface gH expression in absence of gL. We thus demonstrate the ability of distinct cellular processes to regulate the trafficking of viral glycoproteins. Collectively, the data provide insight into the processing and trafficking requirements of CMV envelope protein complexes and provide an example of the co-opting of cellular processes by CMV.

Liberal prostitution policy aims at improving labour conditions for prostitutes and protecting victims of forced prostitution. Its policy orientation predicts that the policy choice of liberalizing prostitution is positively associated with better protection policy for trafficking victims and enhanced anti-trafficking measures. In this paper, I investigate empirically whether the legalization of prostitution improves protection policy for victims, as it is presumed. The results of my analysis...

The cellular response to vascular endothelial growth factors requires co-ordinated signal transduction, trafficking and proteolysis.

VEGFs (vascular endothelial growth factors) are a family of conserved disulfide-linked soluble secretory glycoproteins found in higher eukaryotes. VEGFs mediate a wide range of responses in different tissues including metabolic homoeostasis, cell proliferation, migration and tubulogenesis. Such responses are initiated by VEGF binding to soluble and membrane-bound VEGFRs (VEGF receptor tyrosine kinases) and co-receptors. VEGF and receptor splice isoform diversity further enhances complexity of membrane protein assembly and function in signal transduction pathways that control multiple cellular responses. Different signal transduction pathways are simultaneously activated by VEGFR-VEGF complexes with membrane trafficking along the endosome-lysosome network further modulating signal output from multiple enzymatic events associated with such pathways. Balancing VEGFR-VEGF signal transduction with trafficking and proteolysis is essential in controlling the intensity and duration of different intracellular signalling events. Dysfunction in VEGF-regulated signal transduction is important in chronic disease states including cancer, atherosclerosis and blindness. This family of growth factors and receptors is an important model system for understanding human disease pathology and developing new therapeutics for treating such ailments. © 2015 Authors.

One of the major mechanisms for GPCR regulation involves their endocytic trafficking, which serves to internalize the receptors from the plasma membrane and thereby attenuate G protein-dependent signaling. However, there is accumulating evidence to suggest that GPCRs can signal...... independently of G proteins, as well as from intracellular compartments including endosomes. It is in this context that receptor internalization and intracellular trafficking have attracted renewed interest within the GPCR field.

Health and Rights at the Margins: Human trafficking and HIV/AIDS amongst Jingpo ethnic communities in Ruili City, China

Directory of Open Access Journals (Sweden)

Elena Shih

2013-09-01

Full Text Available In 2007, China and Myanmar signed their first Bilateral Memorandum of Understanding on human trafficking. The two countries cemented this agreement with the unveiling of the first Border Liaison Office in Ruili City, located in China’s southwestern Yunnan Province — one of the primary border crossing points between China and Myanmar. The government focus on human trafficking on this border intersects with decades of struggles to curb the border’s porousness to drugs and HIV/AIDS. This paper is based on qualitative ethnographic participant observation and interviews with young Jingpo women living in Ruili City and investigates the risk of human trafficking as a by-product of cultural stigma associated with ethnic marginality, drugs, and HIV/AIDS. The case of Ruili warns us that the global shift towards regarding human trafficking as the single most perilous phenomenon of the current age obscures ongoing issues of vulnerability and cultural stigma for ethnic minority peoples globally. In lieu of state sponsored patrol and monitoring of the border, more attention must be paid to overlapping concerns of people living in border communities, including drug prevalence, disease, and ethnic marginalisation.

Although NMDAR trafficking mediated by GSK-3β involvement in transmission of pronociceptive messages in the spinal cord has been confirmed by our previous studies, whether NMDAR trafficking is implicated in peripheral sensitization remains equivocal. It is demonstrated that inflammation is associated with spinal NMDAR-containing nociceptive neurons activation and the maintenance of opioid induced pain hypersensitivity. However, whether and how hydrogen-rich saline, as an effective anti-inflammatory drug, could prevent hyperalgesia through affecting peripheral sensitization caused by NMDAR activation remains to be explored. To test these effects, hydrogen-rich saline (2.5, 5 or 10 ml/kg) was administrated intraperitoneally after remifentanil infusion, NMDAR antagonist MK-801 or GSK-3β inhibitor TDZD-8 was administrated intravenously before remifentanil infusion in rats. We examined time course of hydrogen concentration in blood after hydrogen-rich saline administration. Mechanical and thermal hyperalgesia were evaluated by measuring PWT and PWL for 48 post-infusion hours, respectively. Western blotting and real-time qPCR assay were applied to analyze the NR1 membrane trafficking, GSK-3β expression and activity in DRG. Inflammatory mediators (TNF-α, IL-1β, and IL-6) expressions in DRG were also analyzed. We found that NR1 membrane trafficking in DRG increased, possibly due to GSK-3β activation after remifentanil infusion. We also discovered that hydrogen-rich saline not 2.5 ml/kg but 5 and 10 ml/kg could dose-dependently attenuate mechanical and thermal hyperalgesia without affecting baseline nociceptive threshold, reduce expressions of inflammatory mediators (TNF-α, IL-1β, and IL-6) and decrease NR1 trafficking mediated by GSK-3β, and minimal effective concentration was observed to be higher than 10 μmol/L, namely peak concentration in arterial blood after administration of HRS 2.5 ml/kg without any influence on hyperalgesia. Our results indicated that

Effectiveness of Counter-Trafficking Response in Albania

Meçe Merita H.

2016-07-01

Full Text Available Human trafficking is a new phenomenon of Albanian post-socialist society which significantly increased during the difficult years of its transformation from centralized state-led economy to market economy. Both economic and political instability contributed to its size, nature and multiple dynamics. Drawing on a rights-based approach to human trafficking, this paper examines the effectiveness of the counter-trafficking response of the Albanian government with a special emphasis on prevention, protection and prosecution. Using secondary data and reviewing various country strategic documents, it highlights a range of weaknesses and challenges which have hindered its effectiveness over years. It concludes that successful and effective counter-trafficking response requires well rounded and coordinated gender sensitive, victim-centred, holistic and human rights-based efforts. Combined with adequate law enforcement, they will sustainably tackle the full spectrum of this problem.

Engaging Survivors of Human Trafficking: Complex Health Care Needs and Scarce Resources.

Science.gov (United States)

Judge, Abigail M; Murphy, Jennifer A; Hidalgo, Jose; Macias-Konstantopoulos, Wendy

2018-05-01

Human trafficking, also known as modern-day slavery, is an egregious human rights violation associated with wide-ranging medical and mental health consequences. Because of the extensive health problems related to trafficking, health care providers play a critical role in identifying survivors and engaging them in ongoing care. Although guidelines for recognizing affected patients and a framework for developing response protocols in health care settings have been described, survivors' ongoing engagement in health care services is very challenging. High rates of disengagement, lost contact, premature termination, and attrition are common outcomes. For interventions to be effective in this marginalized population, challenges in engaging survivors in long-term therapeutic primary and mental health care must be better understood and overcome. This article uses the socioecological model of public health to identify barriers to engagement; offers evidence- and practice-based recommendations for overcoming these barriers; and proposes an interdisciplinary call to action for developing more flexible, adaptable models of care.

The dynamin chemical inhibitor dynasore impairs cholesterol trafficking and sterol-sensitive genes transcription in human HeLa cells and macrophages.

Directory of Open Access Journals (Sweden)

Emmanuelle Girard

Full Text Available Intracellular transport of cholesterol contributes to the regulation of cellular cholesterol homeostasis by mechanisms that are yet poorly defined. In this study, we characterized the impact of dynasore, a recently described drug that specifically inhibits the enzymatic activity of dynamin, a GTPase regulating receptor endocytosis and cholesterol trafficking. Dynasore strongly inhibited the uptake of low-density lipoprotein (LDL in HeLa cells, and to a lower extent in human macrophages. In both cell types, dynasore treatment led to the abnormal accumulation of LDL and free cholesterol (FC within the endolysosomal network. The measure of cholesterol esters (CE further showed that the delivery of regulatory cholesterol to the endoplasmic reticulum (ER was deficient. This resulted in the inhibition of the transcriptional control of the three major sterol-sensitive genes, sterol-regulatory element binding protein 2 (SREBP-2, 3-hydroxy-3-methyl-coenzymeA reductase (HMGCoAR, and low-density lipoprotein receptor (LDLR. The sequestration of cholesterol in the endolysosomal compartment impaired both the active and passive cholesterol efflux in HMDM. Our data further illustrate the importance of membrane trafficking in cholesterol homeostasis and validate dynasore as a new pharmacological tool to study the intracellular transport of cholesterol.

Highlights: ► Bi-directional (inward and outward) movement of GFP-dysferlin in COS-7 cells. ► Dysferlin interacts with key signaling proteins for transcytosis in EC. ► Dysferlin mediates trafficking of vesicles carrying protein cargos in EC. -- Abstract: Dysferlin is a membrane-anchored protein known to facilitate membrane repair in skeletal muscles following mechanical injury. Mutations of dysferlin gene impair sarcolemma integrity, a hallmark of certain forms of muscular dystrophy in patients. Dysferlin contains seven calcium-dependent C2 binding domains, which are required to promote fusion of intracellular membrane vesicles. Emerging evidence reveal the unexpected expression of dysferlin in non-muscle, non-mechanically active tissues, such as endothelial cells, which cast doubts over the belief that ferlin proteins act exclusively as membrane repair proteins. We and others have shown that deficient trafficking of membrane bound proteins in dysferlin-deficient cells, suggesting that dysferlin might mediate trafficking of client proteins. Herein, we describe the intracellular trafficking and movement of GFP-dysferlin positive vesicles in unfixed reconstituted cells using live microscopy. By performing GST pull-down assays followed by mass spectrometry, we identified dysferlin binding protein complexes in human vascular endothelial cells. Together, our data further support the claims that dysferlin not only mediates membrane repair but also trafficking of client proteins, ultimately, help bridging dysferlinopathies to aberrant membrane signaling.

Survivors of human trafficking who return to their community of origin must cope with the trauma they experienced as victims as well as the conditions that contributed to their trafficking vulnerabilities. In this article, I examine the psychosocial adjustment process among women survivors of trafficking who returned to Vietnam. Supplemented by participation observation, thematic analysis of in-depth interviews with survivors revealed that throughout the trafficking process, the women experienced multiple abuses and changes in relationships and environments. The women coped by navigating a process of "reconstructing a sense of self," seeking congruence between their self-understandings and the changing contextual factors while exhibiting three main coping strategies: regulating emotional expression and thought, creating opportunities within constraints, and relating to cultural schemas. The findings underscore the importance of considering contextual factors such as cultural norms and societal values in efforts to assist trafficked survivors reintegrate into their communities.

The dominant anti-trafficking paradigm conflates trafficking and sex work, denying evidence that most sex workers choose their profession and justifying police actions that disrupt communities, drive sex workers underground and increase vulnerability. We review an alternative response to combating human trafficking and child prostitution in the sex trade, the self-regulatory board (SRB) developed by Durbar Mahila Samanwaya Committee (DMSC, Sonagachi). DMSC-led interventions to remove minors and unwilling women from sex work account for over 80% of successful 'rescues' reported in West Bengal. From 2009 through 2011, 2195 women and girls were screened by SRBs: 170 (7.7%) minors and 45 (2.1%) unwilling adult women were assisted and followed up. The remaining 90.2% received counselling, health care and the option to join savings schemes and other community programmes designed to reduce sex worker vulnerability. Between 1992 and 2011 the proportion of minors in sex work in Sonagachi declined from 25 to 2%. With its universal surveillance of sex workers entering the profession, attention to rapid and confidential intervention and case management, and primary prevention of trafficking-including microcredit and educational programmes for children of sex workers-the SRB approach stands as a new model of success in anti-trafficking work. © The Author 2013.

2009-12-01

Exo- and endocytotic membrane trafficking is an essential process for transport of secretory proteins, extracellular glycans, transporters and lipids in plant cells. Using secretory carrier membrane protein 2 (SCAMP2) as a marker for secretory vesicles and tobacco BY-2 cells as a model system, we recently demonstrated that SCAMP2 positive structures containing secretory materials are transported from the Golgi apparatus to the plasma membrane (PM) and/or cell plate. This structure is consisted with clustered vesicles and was thus named the secretory vesicle cluster (SVC). Here, we have utilized the reversible photoswitching fluorescent protein Dronpa1 to trace the movement of SCAMP2 on the PM and cell plate. Activated SCAMP2-Dronpa fluorescence on the PM and cell plate moved into the BY-2 cells within several minutes, but did not spread around PM. This is consistent with recycling of SCAMP2 among endomembrane compartments such as the TGN, PM and cell plate. The relationship between SVC-mediated trafficking and exo- and endocytosis of plant cells is discussed taking into account this new data and knowledge provided by recent reports.

Child organ trafficking: global reality and inadequate international response.

Science.gov (United States)

Bagheri, Alireza

2016-06-01

In organ transplantation, the demand for human organs has grown far faster than the supply of organs. This has opened the door for illegal organ trade and trafficking including from children. Organized crime groups and individual organ brokers exploit the situation and, as a result, black markets are becoming more numerous and organized organ trafficking is expanding worldwide. While underprivileged and vulnerable men and women in developing countries are a major source of trafficked organs, and may themselves be trafficked for the purpose of illegal organ removal and trade, children are at especial risk of exploitation. With the confirmed cases of children being trafficked for their organs, child organ trafficking, which once called a "modern urban legend", is a sad reality in today's world. By presenting a global picture of child organ trafficking, this paper emphasizes that child organ trafficking is no longer a myth but a reality which has to be addressed. It argues that the international efforts against organ trafficking and trafficking in human beings for organ removal have failed to address child organ trafficking adequately. This chapter suggests that more orchestrated international collaboration as well as development of preventive measure and legally binding documents are needed to fight child organ trafficking and to support its victims.

The Proteome of the Isolated Chlamydia trachomatis Containing Vacuole Reveals a Complex Trafficking Platform Enriched for Retromer Components.

Directory of Open Access Journals (Sweden)

Lukas Aeberhard

2015-06-01

Full Text Available Chlamydia trachomatis is an important human pathogen that replicates inside the infected host cell in a unique vacuole, the inclusion. The formation of this intracellular bacterial niche is essential for productive Chlamydia infections. Despite its importance for Chlamydia biology, a holistic view on the protein composition of the inclusion, including its membrane, is currently missing. Here we describe the host cell-derived proteome of isolated C. trachomatis inclusions by quantitative proteomics. Computational analysis indicated that the inclusion is a complex intracellular trafficking platform that interacts with host cells' antero- and retrograde trafficking pathways. Furthermore, the inclusion is highly enriched for sorting nexins of the SNX-BAR retromer, a complex essential for retrograde trafficking. Functional studies showed that in particular, SNX5 controls the C. trachomatis infection and that retrograde trafficking is essential for infectious progeny formation. In summary, these findings suggest that C. trachomatis hijacks retrograde pathways for effective infection.

Steiner, Jordan J; Kynn, Jamie; Stylianou, Amanda M; Postmus, Judy L

2018-01-01

Human trafficking is a global issue, with survivors representing all genders, ages, races, ethnicities, religions, and countries. However, little research exists that identifies effective practices in supporting survivors of human trafficking. The research that does exist is Western-centric. To fill this gap in the literature, the goal of this research was to understand practices used throughout the globe with adult human trafficking survivors. A qualitative approach was utilized. Providers from 26 countries, across six different continents, were interviewed to allow for a comprehensive and multi-faceted understanding of practices in working with survivors. Participants identified utilizing an empowerment-based, survivor, and human life-centered approach to working with survivors, emphasized the importance of engaging in community level interventions, and highlighted the importance of government recognition of human trafficking. Findings provide information from the perspective of advocates on best practices in the field that can be used by agencies to enhance human trafficking programming.

Accountability and the Use of Raids to Fight Trafficking

Directory of Open Access Journals (Sweden)

Melissa Ditmore

2012-06-01

Full Text Available Accountability in anti-trafficking efforts is a crucial but often overlooked aspect of deciding whether such efforts are truly rooted in a human rights framework. In a rush to help, and inspired by sensationalised views of what human trafficking is, many campaigns actually harm the very people they are supposed to assist. Law enforcement raids are one such effort, as they do not take into account the very different power dynamics between the actor engaging in the raid, and the person who is subject to the raid. Data from the United States suggests that raids conducted by local law enforcement agencies are an ineffective means of locating and identifying trafficked persons. Research also reveals that raids are all too frequently accompanied by violations of the human rights of trafficked persons and sex workers alike, and can therefore be counterproductive to the underlying goals of anti-trafficking initiatives. Findings suggest that a rights-based and “survivor-centred” approach to trafficking in persons requires the development and promotion of alternative methods of identifying and protecting the rights of trafficked persons which prioritise the needs, agency, and self-determination of trafficking survivors. They also indicate that preventative approaches, which address the circumstances that facilitate trafficking in persons, should be pursued over law enforcement based responses.

MUC1 intra-cellular trafficking is clathrin, dynamin, and rab5 dependent

International Nuclear Information System (INIS)

Liu Xiaolong; Yuan Zhenglong; Chung, Maureen

2008-01-01

MUC1, a transmembrane glycoprotein, is abnormally over-expressed in most human adenocarcinomas. MUC1 association with cytoplasmic cell signal regulators and nuclear accumulation are important for its tumor related activities. Little is known about how MUC1 translocates from the cell membrane to the cytoplasm. In this study, live cell imaging was used to study MUC1 intracellular trafficking. The interaction between EGFR and MUC1 was mapped by FRET analysis and EGF stimulated MUC1 endocytosis was observed directly through live cell imaging. MUC1-CT endocytosis was clathrin and dynamin dependent. Rab5 over-expression resulted in decreased cell membrane localization of MUC1, with accumulation of MUC1 endocytic vesicles in the peri-nuclear region. Conversely, over-expression of a Rab5 dominant negative mutant (S34N) resulted in redistribution of MUC1 from the peri-nuclear region to the cytoplasm. Collectively, these results indicated that MUC1 intra-cellular trafficking occurs through a regulated process that was stimulated by direct EGFR and MUC1 interaction, mediated by clathrin coated pits that were dynamin dependent and regulated by Rab5

Shaping the Victim: Borders, security, and human trafficking in Albania

Directory of Open Access Journals (Sweden)

James Campbell

2013-09-01

Full Text Available Borders are productive sites where knowledge is gathered and migrant populations are formed. The knowledge gathered from victims of trafficking reinforces a victim narrative that represents a perceived threat to society by highlighting violence, criminality, coercion, and naivety. Using Albania as a case in point, the article looks at trafficked people and the narratives of victimhood that surround them. In the case of trafficked people, the border projected out towards other states produces a discursively defined victim of trafficking. When projected back within the national territory, the border essentially produces a criminalised sex worker. To argue this point, the article discusses the role victims of trafficking play in the EU and looks at how international norms espoused by the OSCE and IOM have prepped the Albanian border for EU ascension and created the means for governable populations within Albania.

The Hague Recommendations: Improving Nonlegislative Responses to Trafficking in Human Beings for the Purpose of Organ Removal.

Ambagtsheer, Frederike; Weimar, Willem

2016-02-01

Over the years, the trade in human organs has become an object of international concern. Since the 1980s, antiorgan trade initiatives have mainly involved the strengthening of legislative responses. Little attention however is given to nonlegislative responses by law enforcement authorities. The HOTT project is a European Union-funded research project titled "trafficking in human beings for the purpose of organ removal." Its objectives are to increase knowledge, raise awareness, and improve the nonlegislative response to the crime. Its consortium organized a "Writers' Conference" in The Hague, The Netherlands at Europol's Headquarters where a group of 40 experts, consisting of transplant professionals, law enforcement officials, and policy makers, formulated recommendations to improve nonlegislative responses. These recommendations, presented hereafter, address the ethical and legal obligations of health care providers, the protection of persons trafficked for the purpose of organ removal, strengthening cross-border collaboration in criminal cases, and stimulating partnerships between transplant professionals and law enforcement. These recommendations offer ways in which transplant professionals can contribute to improving the nonlegislative response to trafficking in human beings for the purpose of organ removal.

Copper is a transition metal that plays critical roles in many life processes. Controlling the cellular concentration and trafficking of copper offers a route to disrupt these processes. Here we report small molecules that inhibit the human copper-trafficking proteins Atox1 and CCS, and so provide a selective approach to disrupt cellular copper transport. The knockdown of Atox1 and CCS or their inhibition leads to a significantly reduced proliferation of cancer cells, but not of normal cells, as well as to attenuated tumour growth in mouse models. We show that blocking copper trafficking induces cellular oxidative stress and reduces levels of cellular ATP. The reduced level of ATP results in activation of the AMP-activated protein kinase that leads to reduced lipogenesis. Both effects contribute to the inhibition of cancer cell proliferation. Our results establish copper chaperones as new targets for future developments in anticancer therapies.

Spatial separation and bidirectional trafficking of proteins using a multi-functional reporter

Klaubert Dieter H

2008-04-01

Full Text Available Abstract Background The ability to specifically label proteins within living cells can provide information about their dynamics and function. To study a membrane protein, we fused a multi-functional reporter protein, HaloTag®, to the extracellular domain of a truncated integrin. Results Using the HaloTag technology, we could study the localization, trafficking and processing of an integrin-HaloTag fusion, which we showed had cellular dynamics consistent with native integrins. By labeling live cells with different fluorescent impermeable and permeable ligands, we showed spatial separation of plasma membrane and internal pools of the integrin-HaloTag fusion, and followed these protein pools over time to study bi-directional trafficking. In addition to combining the HaloTag reporter protein with different fluorophores, we also employed an affinity tag to achieve cell capture. Conclusion The HaloTag technology was used successfully to study expression, trafficking, spatial separation and real-time translocation of an integrin-HaloTag fusion, thereby demonstrating that this technology can be a powerful tool to investigate membrane protein biology in live cells.

New insights into how trafficking regulates T cell receptor signaling

Directory of Open Access Journals (Sweden)

Jieqiong Lou

2016-07-01

Full Text Available AbstractThere is emerging evidence that exocytosis plays an important role in regulating T cell receptor (TCR signaling. The trafficking molecules involved in lytic granule (LG secretion in cytotoxic T lymphocytes (CTL have been well studied due to the immune disorder known as familial hemophagocytic lymphohisiocytosis (FHLH. However, the knowledge of trafficking machineries regulating the exocytosis of receptors and signaling molecules remains quite limited. In this review, we summarize the reported trafficking molecules involved in the transport of the TCR and downstream signaling molecules to the cell surface. By combining this information with the known knowledge of LG exocytosis and general exocytic trafficking machinery, we attempt to draw a more complete picture of how the TCR signaling network and exocytic trafficking matrix are interconnected to facilitate T cell activation. This also highlights how membrane compartmentalization facilitates the spatiotemporal organization of cellular responses that are essential for immune functions.

Trafficking in human beings: a modern form of slavery or a transnational crime?

Baldwin, Susie B; Fehrenbacher, Anne E; Eisenman, David P

2015-09-01

This study examined coercive conditions experienced by trafficked persons in the context of Biderman's theory of coercion. We conducted semi-structured interviews with 12 adult women trafficked into Los Angeles County, from 10 countries, for domestic work and/or sex work. Participants described health problems they experienced in relation to their trafficking experience and their perceptions of conditions that caused health problems. Utilizing a framework analysis approach, we analyzed themes using Biderman's framework. Participants reported experiencing the range of nonphysical coercive tactics outlined by Biderman, including isolation, monopolization of perception, induced debility or exhaustion, threats, occasional indulgences, demonstration of omnipotence, degradation, and enforcement of trivial demands. Our analysis demonstrates how these coercion tactics reinforced the submission of trafficked persons to their traffickers even in the absence of physical force or restraints. Such psychological abuse creates extreme stress that can lead to acute and chronic, physical and mental health problems. © The Author(s) 2014.

UK medical education on human trafficking: assessing uptake of the opportunity to shape awareness, safeguarding and referral in the curriculum.

Human trafficking is a serious violation of human rights, with numerous consequences for health and wellbeing. Recent law and policy reforms mean that clinicians now hold a crucial role in national strategies. 2015 research, however, indicates a serious shortfall in knowledge and confidence among healthcare professionals in the UK, leading potentially to failures in safeguarding and appropriate referral. Medical education is a central point for trafficking training. We ascertain the extent of such training in UK Medical Schools, and current curricular design. We sent Freedom of Information requests to the 34 public UK medical schools, which included a preliminary question on education provision, supplemented with follow-up questions exploring the nature, delivery and format of any education, as well as future curriculum development. There was a response rate of 97%. A majority (72%) of the schools did not provide trafficking education. 13% of these did, however, offer opportunities outside the formal curriculum. 70% had no plans to implement any education opportunities. Among the 28% of schools providing teaching, 56% integrated this within the core curriculum. 56% only delivered this within a single year of the degree. 67% provided some form of teaching in-person, while 78% used a combination of methods. Medical education on trafficking in the UK is variable and often absent. To produce future clinicians who are competent and capable, there is a need for expanded education on trafficking and research into optimal curriculum design. The UK's new Independent Anti-Slavery Commissioner should work with medical schools to develop an educational strategy urgently to fulfil the UK Government's plans and commitments. Both in the UK and around the world, human trafficking education presents a critical opportunity to address human rights and safeguarding to a generation of new doctors.

Deficiency of legislative shaping of the consent of a victim in human trafficking: Is prostitution prohibited by Palermo protocol?

Directory of Open Access Journals (Sweden)

Ristivojević Branislav R.

2015-01-01

Full Text Available The writer deals in his work with the issue of the consent of a victim to sexual and labor exploitation under the provisions of the Protocol on the Suppression and Punishment of Trafficking in Persons, especially Women and Children on the UN Convention on Transnational Organized Crime. By analyzing preliminary assumptions on which the majority of science stand for, according to which it is possible for a passive subject to consents to its own sexual and labor exploitation, the author finds that the legislative and technical shaping of the relevant provisions of the Protocol is not satisfied concerning this matter. Equalization of all provided manners or instruments of perpetration of criminal offence of human trafficking has brought about a logical error. It is not possible to make equal the effect of coercion and deceit with the effect of providing or accepting the benefits as manners of perpetration of criminal offence of human trafficking on people consent. The first two, if used for sexual exploitation lead to rape instead to human trafficking, which represents a legaldogmatic obstacle to such legislative-technical approach to the Protocol. The second one can lead to human trafficking according to what is given as a provision of this criminal offence, but the writer also complains about decision from the point of a criminal policy. When it comes to sexual exploitation, such legislativetechnical approach along with the consent of the victim covers classical prostitution, and when it comes to labor exploitation the award replaces it as a key mechanism for the regulation of economic relations in ordinary labor markets, with the criminal justice coercion.

A coalition model is often used to serve victims of human trafficking but little is known about whether the model is adequately meeting the needs of the victims. The purpose of this study was to examine anti-human trafficking collaboration model in terms of its impact and the collaborative experience, including challenges and lessons learned from the service providers' perspective. Mixed methods study was conducted to evaluate the impact of a citywide anti-trafficking coalition model from the providers' perspectives. Web-based survey was administered with service providers (n = 32) and focus groups were conducted with Core Group members (n = 10). Providers reported the coalition model has made important impacts in the community by increasing coordination among the key agencies, law enforcement, and service providers and improving quality of service provision. Providers identified the improved and expanded partnerships among coalition members as the key contributing factor to the success of the coalition model. Several key strategies were suggested to improve the coalition model: improved referral tracking, key partner and protocol development, and information sharing.

Sphingomyelin synthases regulate protein trafficking and secretion.

Directory of Open Access Journals (Sweden)

Marimuthu Subathra

Full Text Available Sphingomyelin synthases (SMS1 and 2 represent a class of enzymes that transfer a phosphocholine moiety from phosphatidylcholine onto ceramide thus producing sphingomyelin and diacylglycerol (DAG. SMS1 localizes at the Golgi while SMS2 localizes both at the Golgi and the plasma membrane. Previous studies from our laboratory showed that modulation of SMS1 and, to a lesser extent, of SMS2 affected the formation of DAG at the Golgi apparatus. As a consequence, down-regulation of SMS1 and SMS2 reduced the localization of the DAG-binding protein, protein kinase D (PKD, to the Golgi. Since PKD recruitment to the Golgi has been implicated in cellular secretion through the trans golgi network (TGN, the effect of down-regulation of SMSs on TGN-to-plasma membrane trafficking was studied. Down regulation of either SMS1 or SMS2 significantly retarded trafficking of the reporter protein vesicular stomatitis virus G protein tagged with GFP (VSVG-GFP from the TGN to the cell surface. Inhibition of SMSs also induced tubular protrusions from the trans Golgi network reminiscent of inhibited TGN membrane fission. Since a recent study demonstrated the requirement of PKD activity for insulin secretion in beta cells, we tested the function of SMS in this model. Inhibition of SMS significantly reduced insulin secretion in rat INS-1 cells. Taken together these results provide the first direct evidence that both enzymes (SMS1 and 2 are capable of regulating TGN-mediated protein trafficking and secretion, functions that are compatible with PKD being a down-stream target for SMSs in the Golgi.

Endosome-based protein trafficking and Ca2+ homeostasis in the heart

Jerry eCurran

2015-02-01

Full Text Available The ability to dynamically regulate, traffic, retain, and recycle proteins within the cell membrane is fundamental to life and central to the normal function of the heart and cardiovascular system. In the heart, these systems are essential for the regulation of cardiac calcium, both at the level of the plasma membrane, but also at local domains of the endoplasmic reticulum, sarcoplasmic reticulum, mitochondria, nucleus, and nuclear envelope. One intracellular pathway often overlooked in relation to cardiovascular calcium regulation and signaling is the endosome-based trafficking pathway. Highlighting its importance, this system and its molecular components are evolutionarily conserved across all metazoans. However, remarkably little is known of how endosome-based protein trafficking and recycling functions within mammalian cells systems, especially in the heart. The vast majority of what is known has been derived from heterologous cell systems. However, recently, more appropriate cell and animal models been developed that have allowed researchers to begin to understand how this system functions within the intact physiological environment. All excitable cells, including cardiomyocytes, depend on the proper expression and organization of multiple ion channels, pumps, exchangers, and transporters within the plasma membrane. As the endosomal system acts to regulate the expression and localization of membrane proteins, understanding the in vivo function of this system in the heart is important. This review will focus on endosome-based protein trafficking in the heart in both health and disease. Special emphasis will be given to the role played by the family of endocytic regulatory proteins, C-terminal Eps15 homology domain -containing proteins (EHDs, as recent data demonstrates that this family of proteins is essential for the proper trafficking and localization and of key proteins involved in excitation-contraction coupling.

Prevalence and risk of violence and the physical, mental, and sexual health problems associated with human trafficking: systematic review.

Full Text Available There is very limited evidence on the health consequences of human trafficking. This systematic review reports on studies investigating the prevalence and risk of violence while trafficked and the prevalence and risk of physical, mental, and sexual health problems, including HIV, among trafficked people.We conducted a systematic review comprising a search of Medline, PubMed, PsycINFO, EMBASE, and Web of Science, hand searches of reference lists of included articles, citation tracking, and expert recommendations. We included peer-reviewed papers reporting on the prevalence or risk of violence while trafficked and/or on the prevalence or risk of any measure of physical, mental, or sexual health among trafficked people. Two reviewers independently screened papers for eligibility and appraised the quality of included studies. The search identified 19 eligible studies, all of which reported on trafficked women and girls only and focused primarily on trafficking for sexual exploitation. The review suggests a high prevalence of violence and of mental distress among women and girls trafficked for sexual exploitation. The random effects pooled prevalence of diagnosed HIV was 31.9% (95% CI 21.3%-42.4% in studies of women accessing post-trafficking support in India and Nepal, but the estimate was associated with high heterogeneity (I² = 83.7%. Infection prevalence may be related as much to prevalence rates in women's areas of origin or exploitation as to the characteristics of their experience. Findings are limited by the methodological weaknesses of primary studies and their poor comparability and generalisability.Although limited, existing evidence suggests that trafficking for sexual exploitation is associated with violence and a range of serious health problems. Further research is needed on the health of trafficked men, individuals trafficked for other forms of exploitation, and effective health intervention approaches.

2006-09-01

Full Text Available The authors examine the logistic ecology of 30 large-scale networks that were active in human smuggling and trafficking from Albania and Bulgaria to Belgium (1995–2003. Ten networks were studied in greater detail in order to determine three final profiles of networks, based on their use of structural and operational intermediary structures. They are called the “individual infiltration” and the “structural infiltration” human smuggling patterns, and the “violent-control prostitution” trafficking pattern. It should be noted that the business is organized in such a way that the organizers of the logistical support are never inculpated.

Was Trafficking in Persons Really Criminalised?

Directory of Open Access Journals (Sweden)

Kristiina Kangaspunta

2015-04-01

Full Text Available This paper examines the successes and setbacks in the criminal justice response to trafficking in persons. While today, the majority of countries have passed specific legislation criminalising human trafficking in response to the United Nations Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children, there are still very few convictions of trafficking. Using currently available knowledge, this paper discusses four possible reasons for low conviction rates. Further, the paper suggests that due to the heavy dependency on victim testimonies when prosecuting trafficking in persons crimes, members of criminal organisations that are easily identifiable by victims may face criminal charges more frequently than other members of the criminal group, particularly those in positions of greater responsibility who profit the most from the criminal activities.

Anterograde trafficking of KCa3.1 in polarized epithelia is Rab1- and Rab8-dependent and recycling endosome-independent.

Directory of Open Access Journals (Sweden)

Claudia A Bertuccio

Full Text Available The intermediate conductance, Ca2+-activated K+ channel (KCa3.1 targets to the basolateral (BL membrane in polarized epithelia where it plays a key role in transepithelial ion transport. However, there are no studies defining the anterograde and retrograde trafficking of KCa3.1 in polarized epithelia. Herein, we utilize Biotin Ligase Acceptor Peptide (BLAP-tagged KCa3.1 to address these trafficking steps in polarized epithelia, using MDCK, Caco-2 and FRT cells. We demonstrate that KCa3.1 is exclusively targeted to the BL membrane in these cells when grown on filter supports. Following endocytosis, KCa3.1 degradation is prevented by inhibition of lysosomal/proteosomal pathways. Further, the ubiquitylation of KCa3.1 is increased following endocytosis from the BL membrane and PR-619, a deubiquitylase inhibitor, prevents degradation, indicating KCa3.1 is targeted for degradation by ubiquitylation. We demonstrate that KCa3.1 is targeted to the BL membrane in polarized LLC-PK1 cells which lack the μ1B subunit of the AP-1 complex, indicating BL targeting of KCa3.1 is independent of μ1B. As Rabs 1, 2, 6 and 8 play roles in ER/Golgi exit and trafficking of proteins to the BL membrane, we evaluated the role of these Rabs in the trafficking of KCa3.1. In the presence of dominant negative Rab1 or Rab8, KCa3.1 cell surface expression was significantly reduced, whereas Rabs 2 and 6 had no effect. We also co-immunoprecipitated KCa3.1 with both Rab1 and Rab8. These results suggest these Rabs are necessary for the anterograde trafficking of KCa3.1. Finally, we determined whether KCa3.1 traffics directly to the BL membrane or through recycling endosomes in MDCK cells. For these studies, we used either recycling endosome ablation or dominant negative RME-1 constructs and determined that KCa3.1 is trafficked directly to the BL membrane rather than via recycling endosomes. These results are the first to describe the anterograde and retrograde trafficking of KCa3

Phosphoinositides, Major Actors in Membrane Trafficking and Lipid Signaling Pathways

Directory of Open Access Journals (Sweden)

Johan-Owen De Craene

2017-03-01

Full Text Available Phosphoinositides are lipids involved in the vesicular transport of proteins and lipids between the different compartments of eukaryotic cells. They act by recruiting and/or activating effector proteins and thus are involved in regulating various cellular functions, such as vesicular budding, membrane fusion and cytoskeleton dynamics. Although detected in small concentrations in membranes, their role is essential to cell function, since imbalance in their concentrations is a hallmark of many cancers. Their synthesis involves phosphorylating/dephosphorylating positions D3, D4 and/or D5 of their inositol ring by specific lipid kinases and phosphatases. This process is tightly regulated and specific to the different intracellular membranes. Most enzymes involved in phosphoinositide synthesis are conserved between yeast and human, and their loss of function leads to severe diseases (cancer, myopathy, neuropathy and ciliopathy.

The Fight against the Least Visible Form of Human Trafficking: Trafficking for Child Labour Exploitation

Luz María Puente Aba

2018-03-01

Full Text Available Child trafficking for the purpose of labour exploitation is a difficult phenomenon to detect. It is also not readily definable considering that this specific form of trafficking is closely linked with the phenomenon of forced child labour, and even with the broader occurrence of child labour. A lack of globally reliable data and the convergence of different concepts related to child trafficking for labour exploitation pose significant challenges when trying to regulate the circumstances concerning child work and the criminalisation of trafficking for labour exploitation. This article offers a clear overview of the available data related to all the phenomena, and aims to clarify all the situations involved, defining child work, child labour, forced child labour and child trafficking for the purposes of labour exploitation. Furthermore, this article discusses the possible loopholes and critical issues that could hinder global approaches to resolving these issues. La trata infantil con fines de explotación laboral es un fenómeno difícil de detectar, y tampoco es sencillo definirlo si se tiene en cuenta que esta forma específica de trata está estrechamente relacionada con el fenómeno del trabajo forzado infantil e, incluso, con el fenómeno más general de trabajo infantil. Todo ello supone un desafío a la hora de regular las circunstancias que definen el trabajo realizado por niños y la criminalización de la trata para la explotación laboral. Este artículo ofrece un repaso de los datos disponibles en esta materia y procura aclarar las situaciones que se pueden plantear, así como definir trabajo realizado por niños, trabajo infantil, trabajo infantil forzado y trata infantil con fines de explotación laboral. Por último, profundiza en las posibles deficiencias y en los aspectos críticos que podrían obstaculizar un acercamiento global a esta problemática.

Human papillomaviruses enter host cells via a clathrin-independent endocytic pathway involving tetraspanin proteins. However, post-endocytic trafficking required for virus capsid disassembly remains unclear. Here we demonstrate that the early trafficking pathway of internalised HPV particles involves tetraspanin CD63, syntenin-1 and ESCRT-associated adaptor protein ALIX. Following internalisation, viral particles are found in CD63-positive endosomes recruiting syntenin-1, a CD63-interacting adaptor protein. Electron microscopy and immunofluorescence experiments indicate that the CD63-syntenin-1 complex controls delivery of internalised viral particles to multivesicular endosomes. Accordingly, infectivity of high-risk HPV types 16, 18 and 31 as well as disassembly and post-uncoating processing of viral particles was markedly suppressed in CD63 or syntenin-1 depleted cells. Our analyses also present the syntenin-1 interacting protein ALIX as critical for HPV infection and CD63-syntenin-1-ALIX complex formation as a prerequisite for intracellular transport enabling viral capsid disassembly. Thus, our results identify the CD63-syntenin-1-ALIX complex as a key regulatory component in post-endocytic HPV trafficking.

Huang, Lanying

2017-11-09

Prior to the passing of 2009 Human Trafficking Prevention Act (HTPA), human trafficking was underestimated in Taiwan. In the past, domestic trafficking in women and girls often targeted vulnerable groups such as young girls from poor families or minority groups. Since the 1990s, an increasing flow of immigrant women, mainly from Vietnam and Indonesia and some from China, into Taiwan has created a new group of Human Trafficking victims. The current study intends to identify, describe, and categorize reported and prosecuted human trafficking cases involving women and girls according to the HTPA in Taiwan. Using the court proceedings of prosecuted trafficking in women and girls cases under Taiwan's HTPA from all 21 districts in Taiwan from 2009 to 2012 under the title keyword of 'Human Trafficking', this current study aims to categorize different patterns of existing trafficking in women and girls in Taiwan. The analysis is based on 37 court cases, involving 195 victimized women and girls and 118 perpetrators. This study identifies six forms of Human Trafficking victims according to their country of origin, vulnerability status, and means of transport. This study found that women and girls suffer from both labor and sexual exploitation, from mainly domestic male perpetrators. While sexual exploitation is more evenly distributed among citizens and immigrants and affects both adults and minors, labor exploitation seems to be an exclusive phenomenon among women immigrant workers in the data. Human Trafficking cases in Taiwan share many of the similarities of Human Trafficking in other regions, which are highly associated with gender inequality and gender-based vulnerability.

A Tyrosine-Based Trafficking Motif of the Tegument Protein pUL71 Is Crucial for Human Cytomegalovirus Secondary Envelopment.

Science.gov (United States)

Dietz, Andrea N; Villinger, Clarissa; Becker, Stefan; Frick, Manfred; von Einem, Jens

2018-01-01

The human cytomegalovirus (HCMV) tegument protein pUL71 is required for efficient secondary envelopment and accumulates at the Golgi compartment-derived viral assembly complex (vAC) during infection. Analysis of various C-terminally truncated pUL71 proteins fused to enhanced green fluorescent protein (eGFP) identified amino acids 23 to 34 as important determinants for its Golgi complex localization. Sequence analysis and mutational verification revealed the presence of an N-terminal tyrosine-based trafficking motif (YXXΦ) in pUL71. This led us to hypothesize a requirement of the YXXΦ motif for the function of pUL71 in infection. Mutation of both the tyrosine residue and the entire YXXΦ motif resulted in an altered distribution of mutant pUL71 at the plasma membrane and in the cytoplasm during infection. Both YXXΦ mutant viruses exhibited similarly decreased focal growth and reduced virus yields in supernatants. Ultrastructurally, mutant-virus-infected cells exhibited impaired secondary envelopment manifested by accumulations of capsids undergoing an envelopment process. Additionally, clusters of capsid accumulations surrounding the vAC were observed, similar to the ultrastructural phenotype of a UL71-deficient mutant. The importance of endocytosis and thus the YXXΦ motif for targeting pUL71 to the Golgi complex was further demonstrated when clathrin-mediated endocytosis was inhibited either by coexpression of the C-terminal part of cellular AP180 (AP180-C) or by treatment with methyl-β-cyclodextrin. Both conditions resulted in a plasma membrane accumulation of pUL71. Altogether, these data reveal the presence of a functional N-terminal endocytosis motif that is an important determinant for intracellular localization of pUL71 and that is furthermore required for the function of pUL71 during secondary envelopment of HCMV capsids at the vAC. IMPORTANCE Human cytomegalovirus (HCMV) is the leading cause of birth defects among congenital virus infections and can

The human immunodeficiency virus type 1 (HIV-1) envelope glycoprotein (Env) encodes specific trafficking signals within its long cytoplasmic tail (CT) that regulate incorporation into HIV-1 particles. Rab11-family interacting protein 1C (FIP1C) and Rab14 are host trafficking factors required for Env particle incorporation, suggesting that Env undergoes sorting from the endosomal recycling compartment (ERC) to the site of particle assembly on the plasma membrane. We disrupted outward sorting from the ERC by expressing a C-terminal fragment of FIP1C (FIP1C 560-649 ) and examined the consequences on Env trafficking and incorporation into particles. FIP1C 560-649 reduced cell surface levels of Env and prevented its incorporation into HIV-1 particles. Remarkably, Env was trapped in an exaggerated perinuclear ERC in a CT-dependent manner. Mutation of either the Yxxϕ endocytic motif or the YW 795 motif in the CT prevented Env trapping in the ERC and restored incorporation into particles. In contrast, simian immunodeficiency virus SIVmac239 Env was not retained in the ERC, while substitution of the HIV-1 CT for the SIV CT resulted in SIV Env retention in this compartment. These results provide the first direct evidence that Env traffics through the ERC and support a model whereby HIV-1 Env is specifically targeted to the ERC prior to FIP1C- and CT-dependent outward sorting to the particle assembly site on the plasma membrane. IMPORTANCE The HIV envelope protein is an essential component of the viral particle. While many aspects of envelope protein structure and function have been established, the pathway it follows in the cell prior to reaching the site of particle assembly is not well understood. The envelope protein has a very long cytoplasmic tail that interacts with the host cell trafficking machinery. Here, we utilized a truncated form of the trafficking adaptor FIP1C protein to arrest the intracellular transport of the envelope protein, demonstrating that it becomes

Powdery mildew fungi form feeding structures called haustoria inside epidermal cells of host plants to extract photosynthates for their epiphytic growth and reproduction. The haustorium is encased by an interfacial membrane termed the extrahaustorial membrane (EHM). The atypical resistance protein RPW8.2 from Arabidopsis is specifically targeted to the EHM where RPW8.2 activates haustorium-targeted (thus broad-spectrum) resistance against powdery mildew fungi. EHM-specific localization of RPW8.2 suggests the existence of an EHM-oriented protein/membrane trafficking pathway during EHM biogenesis. However, the importance of this specific trafficking pathway for host defense has not been evaluated via a genetic approach without affecting other trafficking pathways. Here, we report that expression of EHM-oriented, nonfunctional RPW8.2 chimeric proteins exerts dominant negative effect over functional RPW8.2 and potentially over other EHM-localized defense proteins, thereby compromising both RPW8.2-mediated and basal resistance to powdery mildew. Thus, our results highlight the importance of the EHM-oriented protein/membrane trafficking pathway for host resistance against haustorium-forming pathogens such as powdery mildew fungi.

STARD4 knockdown in HepG2 cells disrupts cholesterol trafficking associated with the plasma membrane, ER, and ERC.

2012-12-01

STARD4, a member of the evolutionarily conserved START gene family, has been implicated in the nonvesicular intracellular transport of cholesterol. However, the direction of transport and the membranes with which this protein interacts are not clear. We present studies of STARD4 function using small hairpin RNA knockdown technology to reduce STARD4 expression in HepG2 cells. In a cholesterol-poor environment, we found that a reduction in STARD4 expression leads to retention of cholesterol at the plasma membrane, reduction of endoplasmic reticulum-associated cholesterol, and decreased ACAT synthesized cholesteryl esters. Furthermore, D4 KD cells exhibited a reduced rate of sterol transport to the endocytic recycling compartment after cholesterol repletion. Although these cells displayed normal endocytic trafficking in cholesterol-poor and replete conditions, cell surface low density lipoprotein receptor (LDLR) levels were increased and decreased, respectively. We also observed a decrease in NPC1 protein expression, suggesting the induction of compensatory pathways to maintain cholesterol balance. These data indicate a role for STARD4 in nonvesicular transport of cholesterol from the plasma membrane and the endocytic recycling compartment to the endoplasmic reticulum and perhaps other intracellular compartments as well.

How do social determinants affect human trafficking in Southeast Asia, and what can we do about it? A systematic review.

Science.gov (United States)

Perry, Kelsey McGregor; McEwing, Lindsay

2013-12-12

The sale of women and children accounts for the greatest proportion of human trafficking globally, with Southeast Asia acting as the illegal industry's largest international hub. At least 225,000 women and children are trafficked from the region every year, accounting for approximately one-third of the global human trade. The health ramifications of trafficking are severe: many survivors contract infectious diseases including sexually transmitted infections and develop mental health conditions, including anxiety, panic disorder, and major depression. The complications associated with studying a highly secretive illegal trade have severely limited research on effective prevention measures. Because this presents a challenge for organizations that hope to develop prevention strategies, we asked the following question: How do social determinants facilitate or mitigate trafficking of women and children in Southeast Asia, and what recommendations does the literature provide for combating trafficking via these social determinants? Using a Cochrane-based systematic search methodology, five independent researchers reviewed 1,148 articles from the past ten years (2001–2011). After three phases of independent review, they selected and analyzed 61 articles to identify the determinants that impact trafficking of women and children in Southeast Asia. Key social determinants that facilitate trafficking include poverty, female gender, lack of policy and enforcement, age, migration, displacement and conflict, ethnicity, culture, ignorance of trafficking methods, and caste status. Conversely, protective determinants that mitigate trafficking include formal education, citizenship, maternal education, higher caste status, and birth order. Recommendations relating to a variety of the determinants are identified and discussed in detail. Social determinants are central to the processes that mitigate and facilitate the sale and exploitation of women and children in Southeast Asia

Laila Cigana Schenkel

2014-01-01

Full Text Available Mitochondrial membrane phospholipids are essential for the mitochondrial architecture, the activity of respiratory proteins, and the transport of proteins into the mitochondria. The accumulation of phospholipids within mitochondria depends on a coordinate synthesis, degradation, and trafficking of phospholipids between the endoplasmic reticulum (ER and mitochondria as well as intramitochondrial lipid trafficking. Several studies highlight the contribution of dietary fatty acids to the remodeling of phospholipids and mitochondrial membrane homeostasis. Understanding the role of phospholipids in the mitochondrial membrane and their metabolism will shed light on the molecular mechanisms involved in the regulation of mitochondrial function and in the mitochondrial-related diseases.

Nuclear functions and subcellular trafficking mechanisms of the epidermal growth factor receptor family

Science.gov (United States)

2012-01-01

Accumulating evidence suggests that various diseases, including many types of cancer, result from alteration of subcellular protein localization and compartmentalization. Therefore, it is worthwhile to expand our knowledge in subcellular trafficking of proteins, such as epidermal growth factor receptor (EGFR) and ErbB-2 of the receptor tyrosine kinases, which are highly expressed and activated in human malignancies and frequently correlated with poor prognosis. The well-characterized trafficking of cell surface EGFR is routed, via endocytosis and endosomal sorting, to either the lysosomes for degradation or back to the plasma membrane for recycling. A novel nuclear mode of EGFR signaling pathway has been gradually deciphered in which EGFR is shuttled from the cell surface to the nucleus after endocytosis, and there, it acts as a transcriptional regulator, transmits signals, and is involved in multiple biological functions, including cell proliferation, tumor progression, DNA repair and replication, and chemo- and radio-resistance. Internalized EGFR can also be transported from the cell surface to several intracellular compartments, such as the Golgi apparatus, the endoplasmic reticulum, and the mitochondria, in addition to the nucleus. In this review, we will summarize the functions of nuclear EGFR family and the potential pathways by which EGFR is trafficked from the cell surface to a variety of cellular organelles. A better understanding of the molecular mechanism of EGFR trafficking will shed light on both the receptor biology and potential therapeutic targets of anti-EGFR therapies for clinical application.

Child trafficking and the European migration crisis: The role of forensic practitioners.

Science.gov (United States)

Obertová, Zuzana; Cattaneo, Cristina

2018-01-01

Trafficking in children is one of the worst forms of human rights violation and is categorised as a serious crime. Children at high risk of becoming victims of trafficking are runaways, children with a history of abuse, and migrant children. Internationally, cases of child trafficking are increasing the most in Europe, which is likely the result of the current migration crisis. In crises, preventing and combating human trafficking needs to be prioritized, considering that the aims of humanitarian action include saving lives, easing suffering and preserving human dignity. The involvement of forensic practitioners in investigations of cases of child trafficking mainly concerning the identification of victims may save lives and certainly alleviate suffering of the child victims and their families searching for them. Moreover, by aiding the prosecution process through thorough documentation and expert reporting forensic practitioners may contribute to the protection, rehabilitation and possibly compensation of the child victims, and thus to the restoration of their rights and dignity. So far, forensic practitioners were rarely specifically mentioned as actors in the counter-trafficking efforts in the multitude of policies, regulations, guidelines and recommendations concerning different aspects of child trafficking. This seems surprising considering that the expertise and experience of practitioners from forensic sciences including cyber forensics, document analysis, forensic biology, anthropology, and medicine can be utilised for gathering intelligence in cases of suspected human trafficking, for identifying the victims as well as perpetrators, and for securing evidence for legal proceedings as this paper shows. While this article mainly discusses the role of forensic pathologists and anthropologists, with a specific focus on the identification of child victims of trafficking in the context of the European migration crisis, the notions regarding the contribution of

We present here evidence of in vivo epithelial endocytosis and trafficking of non-lipid-modified Sonic hedgehog (ShhN) when infused into rat efferent ducts via microinjection. Initially, exogenous ShhN is detected in endocytic vesicles and early endosomes located near the apical plasma membrane of non-ciliated cells. Within 30-60 min following infusion, ShhN can be detected in lysosomes and at basolateral regions of non-ciliated cells. Basolaterally, ShhN was observed along the extracellular surfaces of interdigitated plasma membranes of adjacent cells and in the extracellular compartment underlying the efferent duct epithelium. Uptake and subcellular trafficking of infused ShhN by non-ciliated cells could be blocked by either anti-megalin IgG or the megalin antagonist, RAP. Ciliated cells, which do not express megalin, displayed little if any apical internalization of ShhN even though they were found to express Patched-1. However, ShhN was found in coated pits of lateral plasma membranes of ciliated cells as well as in underlying endocytic vesicles. We conclude that megalin-mediated endocytosis of ShhN can occur in megalin-expressing epithelia in vivo, and that the internalized ShhN can be targeted to the lysosome or transcytosed in the plane of the epithelium or across the epithelium. These findings highlight the multiple mechanisms by which megalin may influence Shh morphogen gradients in vivo.

PSYCHOLOGICAL FACTORS INCREASING THE RISK FOR ADOLESCENT GIRLS TO BECOME VICTIMS OF HUMAN TRAFFICKING: A SYSTEMATIC REVIEW

Directory of Open Access Journals (Sweden)

Kristina Vrubliauskaitė

2018-05-01

Full Text Available Most of the research on the risk for minors to become victims of human trafficking or commercial sexual exploitation up till recently focused on socioeconomic, psychosocial and demographic factors. As findings suggest, these characteristics have different impact across different cultures, regions, etc., thus scholars are starting to raise the question on their differen timpact on individual level. They notice that, in the presence of particular combination of characteristics, adolescent girls do not always become victims of commercial sexual exploitation, and some girls who are considered to be victims do not see themselves as victims of sexual exploitation. The aim of this article is to systematically overview psychological factors found through research, that are associated with the risk of becoming a victim of human trafficking. The systematic review focuses on commercial sexual exploitation of minors, particularly, girls, as the most prevalent form of human trafficking. Criteria for article selection include language of the article, the scope and methodology of the research done, sex of the participants of the research, age of being trafficked, and nature of risk factors analysed in the article. Final analysis comprised of six articles. The results show that risk of becoming victim of commercial sexual exploitation is linked with such psychological factors as low self-esteem, denigration of sexual self and others, dysfunctional attachment models, learned maladaptive problem solving strategies, and post-traumatic stress disorder, lack of reflecting abilities, etc. These psychological characteristics may emerge after traumatic experiences such as loss, sexual abuse in childhood, multiple placements in foster care or maltreatment of the child, and later lead into risky behaviours like running away from homes, living on the streets, which increase risk of their exploitation. Results and future research suggestions are discussed.

Domestic Sex Trafficking of Minors: Medical Student and Physician Awareness.

Titchen, Kanani E; Loo, Dyani; Berdan, Elizabeth; Rysavy, Mary Becker; Ng, Jessica J; Sharif, Iman

2017-02-01

Our aim was to assess: (1) medical trainee and practicing physician awareness about domestic sex trafficking of minors; and (2) whether respondents believe that awareness of trafficking is important to their practice. We designed an anonymous electronic survey, and a convenience sample was collected from June through October 2013. Voluntary participants were 1648 medical students, residents, and practicing physicians throughout the United States. Data were analyzed for correlations between study cohort characteristics and: (1) agreement with the statement: "knowing about sex trafficking in my state is important to my profession"; (2) knowledge of national statistics regarding the sex trafficking of minors; and (3) knowledge of appropriate responses to encountering a trafficked victim. More practicing physicians than residents or medical students: (1) agreed or strongly agreed that knowledge about human trafficking was important to their practice (80.6%, 71.1%, and 69.2%, respectively; P = .0008); (2) correctly estimated the number of US trafficked youth according to the US Department of State data (16.1%, 11.7%, and 7.9%, respectively; P = .0011); and (3) were more likely to report an appropriate response to a trafficked victim (40.4%, 20.4%, and 8.9%, respectively; P = .0001). Although most medical trainees and physicians place importance on knowing about human trafficking, they lack knowledge about the scope of the problem, and most would not know where to turn if they encountered a trafficking victim. There exists a need for standardized trafficking education for physicians, residents, and medical students. Copyright © 2015 North American Society for Pediatric and Adolescent Gynecology.

Full Text Available The European Union (EU’s current provisions on the trafficking in human beings (THB are provided for, inter alia, in Council Framework Decision 2002/629/JHA. The Council of Europe have more recent provisions in this area, which are not yet widely in force. The EU has some major proposals for reform of its legal framework in the Stockholm Programme, to include the appointment of an EU Anti-Trafficking Coordinator. In addition, the focus of EU Justice and Home Affairs is shifting to the external relations of the EU under the Stockholm Programme. A critical examination of the EU legal framework in the area of THB from a law enforcement perspective is therefore timely. THB is a highly contentious and complicated area for regulation, with issues such as the support of the victims of trafficking, the particular needs of under-aged trafficked individuals, and the issues of due process when a witness may not be considered to be reliable during court proceedings, complicating operations and prosecutions. In addition the issue of illegal immigration adds a further layer of complication, with the UK maintaining its opt out from the EU’s illegal immigration provisions. This article will, focus on the illegal trafficking of adults against their will, and the consequences of this crime, in particular, for the UK law enforcement authorities.

Biopolitical management, economic calculation and "trafficked women".

Narratives surrounding human trafficking, especially trafficking in women for sex work, employ gendered and racialized tropes that have among their effects, a shrouding of women's economic decision-making and state collusion in benefiting from their labour. This paper explores the operation of these narratives in order to understand the ways in which they mask the economics of trafficking by sensationalizing the sexual and criminal aspects of it, which in turn allows the state to pursue political projects under the guise of a benevolent concern for trafficked women and/or protection of its own citizens. This paper will explore one national example: Article 18 of Italian Law 40 (1998). I argue that its passage has led to an increase in cooperation with criminal prosecution of traffickers largely because it approaches trafficked women as capable of making decisions about how and what they themselves want to do. This paper will also consider a more global approach to trafficking embedded in the concept of "migration management", an International Organization for Migration (IOM) framework that is now shaping EU, US and other national immigration laws and policies that impact trafficking. It will also examine the inherent limitations of both the national and global approach as an occasion to unpack how Article 18 and Migration Management function as forms of biopolitical management that participate in the production of "trafficking victims" into a massified population to be managed, rather than engender a more engaged discussion of what constitutes trafficking and how to redress it.

"The perfect business": human trafficking and Lao-Thai cross-border migration.

Over the past few years some governments and development organizations have increasingly articulated cross-border mobility as "trafficking in persons". The notion of a market where traffickers prey on the "supply" of migrants that flows across international borders to meet the "demand" for labour has become a central trope among anti-trafficking development organizations. This article problematizes such economism by drawing attention to the oscillating cross-border migration of Lao sex workers within a border zone between Laos and Thailand. It illuminates the incongruity between the recruitment of women into the sex industry along the Lao-Thai border and the market models that are employed by the anti-trafficking sector. It discusses the ways in which these cross-border markets are conceived in a context where aid programming is taking on an increasingly important role in the politics of borders. The author concludes that allusions to ideal forms of knowledge (in the guise of classic economic theory) and an emphasis on borders become necessary for anti-trafficking programmes in order to make their object of intervention legible as well as providing post-hoc rationalizations for their continuing operation.

Live-cell imaging is used to simultaneously capture time-lapse images of angiotensin type 1a receptors (AT1aR) and intracellular compartments in transfected human embryonic kidney-293 (HEK) cells following stimulation with angiotensin II (Ang II). HEK cells are transiently transfected with plasmid DNA containing AT1aR tagged with enhanced green fluorescent protein (EGFP). Lysosomes are identified with a red fluorescent dye. Live-cell images are captured on a laser scanning confocal microscope after Ang II stimulation and analyzed by software in three dimensions (3D, voxels) over time. Live-cell imaging enables investigations into receptor trafficking and avoids confounds associated with fixation, and in particular, the loss or artefactual displacement of EGFP-tagged membrane receptors. Thus, as individual cells are tracked through time, the subcellular localization of receptors can be imaged and measured. Images must be acquired sufficiently rapidly to capture rapid vesicle movement. Yet, at faster imaging speeds, the number of photons collected is reduced. Compromises must also be made in the selection of imaging parameters like voxel size in order to gain imaging speed. Significant applications of live-cell imaging are to study protein trafficking, migration, proliferation, cell cycle, apoptosis, autophagy and protein-protein interaction and dynamics, to name but a few.

The Role of Rab Proteins in Neuronal Cells and in the Trafficking of Neurotrophin Receptors

Full Text Available Neurotrophins are a family of proteins that are important for neuronal development, neuronal survival and neuronal functions. Neurotrophins exert their role by binding to their receptors, the Trk family of receptor tyrosine kinases (TrkA, TrkB, and TrkC and p75NTR, a member of the tumor necrosis factor (TNF receptor superfamily. Binding of neurotrophins to receptors triggers a complex series of signal transduction events, which are able to induce neuronal differentiation but are also responsible for neuronal maintenance and neuronal functions. Rab proteins are small GTPases localized to the cytosolic surface of specific intracellular compartments and are involved in controlling vesicular transport. Rab proteins, acting as master regulators of the membrane trafficking network, play a central role in both trafficking and signaling pathways of neurotrophin receptors. Axonal transport represents the Achilles' heel of neurons, due to the long-range distance that molecules, organelles and, in particular, neurotrophin-receptor complexes have to cover. Indeed, alterations of axonal transport and, specifically, of axonal trafficking of neurotrophin receptors are responsible for several human neurodegenerative diseases, such as Huntington’s disease, Alzheimer’s disease, amyotrophic lateral sclerosis and some forms of Charcot-Marie-Tooth disease. In this review, we will discuss the link between Rab proteins and neurotrophin receptor trafficking and their influence on downstream signaling pathways.

In cycling cells cytosolic de novo synthesis of deoxynucleotides is the main source of precursors for mitochondrial (mt) DNA synthesis. The transfer of deoxynucleotides across the inner mt membrane requires protein carriers. PNC1, a SLC25 family member, exchanges pyrimidine nucleoside triphosphates in liposomes and its downregulation decreases mtUTP concentration in cultured cells. By an isotope-flow protocol we confirmed transport of uridine nucleotides by PNC1 in intact cultured cells and investigated PNC1 involvement in the mt trafficking of thymidine phosphates. Key features of our approach were the manipulation of PNC1 expression by RNA interference or inducible overexpression, the employment of cells proficient or deficient for cytosolic thymidine kinase (TK1) to distinguish the direction of flow of thymidine nucleotides across the mt membrane during short pulses with [{sup 3}H]-thymidine, the determination of mtdTTP specific radioactivity to quantitate the rate of mtdTTP export to the cytoplasm. Downregulation of PNC1 in TK1{sup -} cells increased labeled dTTP in mitochondria due to a reduced rate of export. Overexpression of PNC1 in TK1{sup +} cells increased mtdTTP pool size and radioactivity, suggesting an involvement in the import of thymidine phosphates. Thus PNC1 is a component of the network regulating the mtdTTP pool in human cells. -- Highlights: Black-Right-Pointing-Pointer Thymidine phosphates exchange between mitochondria and cytosol in mammalian cells. Black-Right-Pointing-Pointer siRNA-downregulation of PNC1 delays mitochondrial dTTP export in TK1{sup -} cells. Black-Right-Pointing-Pointer PNC1 overexpression accumulates dTTP in mitochondria of TK1{sup +} cells. Black-Right-Pointing-Pointer PNC1 exchanges thymidine nucleotides across the mitochondrial inner membrane. Black-Right-Pointing-Pointer PNC1 participates in the regulation of the mtdTTP pool supporting mtDNA synthesis.

Despite increased effort to respond to human trafficking at national and state levels, very little empirical research has been conducted on domestic child sex trafficking. This study retrospectively examines associations between multiple risk factors and domestic child sex trafficking (i.e., entry into the commercial sex industry under the age of 18) in a sample of individuals aged 16 and older currently involved in the commercial sex industry ( N = 273). Two primary research questions are addressed: (1) What set of risk factors, prior to entering the commercial sex industry, are associated with domestic child sex trafficking and (2) what group differences, if any, exist in risk factors between current or former domestic child sex-trafficking victims and non-trafficked adults engaged in the commercial sex industry? A cross-sectional survey was administered using Respondent-Driven Sampling (RDS) in five cities in one Midwestern state. Overall, 115 participants (48.3%) were identified as current or former domestic child sex-trafficking victims. Bivariate results suggest that childhood emotional and sexual abuse, rape, ever running away from home, having family members in sex work, and having friends who purchased sex were significantly associated with domestic child sex trafficking. Multivariate results indicate that domestic child sex trafficking victims were significantly more likely to have ever run away and to be a racial/ethnic minority than non-trafficked adults engaged in the commercial sex industry. Findings can inform state-level policies on human trafficking and assist child protection and juvenile justice agencies in developing prevention and intervention responses to commercial sexual exploitation.

To update and expand on a 2012 systematic review of the prevalence and risk of violence and the prevalence and risk of physical, mental and sexual health problems among trafficked people. Systematic review and meta-analysis. Searches of 15 electronic databases of peer-reviewed articles and doctoral theses were supplemented by reference screening, citation tracking of included articles and expert recommendations. Studies were included if they reported on the prevalence or risk of violence while trafficked, or the prevalence or risk of physical, mental or sexual health outcomes among people who have been trafficked. Two reviewers independently screened papers for eligibility and appraised the quality of included studies. Thirty-seven papers reporting on 31 studies were identified. The majority of studies were conducted in low and middle-income countries with women and girls trafficked into the sex industry. There is limited but emerging evidence on the health of trafficked men and the health consequences of trafficking into different forms of exploitation. Studies indicate that trafficked women, men and children experience high levels of violence and report significant levels of physical health symptoms, including headaches, stomach pain and back pain. Most commonly reported mental health problems include depression, anxiety and post-traumatic stress disorder. Although serological data on sexually transmitted infections are limited, women and girls trafficked for sexual exploitation self-report symptoms suggestive of a high prevalence of infections. Limitations of the review include methodological weaknesses of primary studies and some differences in definition and operationalisation of trafficking, which hinder comparability and generalisability of the results. There is increasing evidence human trafficking is associated with high prevalence and increased risk of violence and a range of physical and mental health problems.
