Full Text Available Interleukin(IL-35 is a new member of the interleukin-12 superfamily. Since its first report in 2007, IL-35 rapidly became a research highlight in the field of immunology. Like other IL-12 superfamily members, IL-35 was a heterodimer which was composed of an α chain P35 and a β chain Epstein-Barr virus induced gene 3 (EBI3. Recent research work revealed two distinct roles of IL-35. Firstly, IL-35 is highly expressed in some kinds of inflammatory diseases and autoimmune diseases and plays import roles in the pathogenesis. Secondly, IL-35 is positively expressed in some cancers and plays some roles in the process of tumor progression. Here we demonstrate the structure and the signalling of IL-35. We reviewed the the roles of IL-35 in promoting tumor progression.

IL-4 Receptor Alpha Signaling through Macrophages Differentially Regulates Liver Fibrosis Progression and Reversal

Full Text Available Chronic hepatitis leads to liver fibrosis and cirrhosis. Cirrhosis is a major cause of worldwide morbidity and mortality. Macrophages play a key role in fibrosis progression and reversal. However, the signals that determine fibrogenic vs fibrolytic macrophage function remain ill defined. We studied the role of interleukin-4 receptor α (IL-4Rα, a potential central switch of macrophage polarization, in liver fibrosis progression and reversal. We demonstrate that inflammatory monocyte infiltration and liver fibrogenesis were suppressed in general IL-4Rα−/− as well as in macrophage-specific IL-4Rα−/− (IL-4RαΔLysM mice. However, with deletion of IL-4RαΔLysM spontaneous fibrosis reversal was retarded. Results were replicated by pharmacological intervention using IL-4Rα-specific antisense oligonucleotides. Retarded resolution was linked to the loss of M2-type resident macrophages, which secreted MMP-12 through IL-4 and IL-13-mediated phospho-STAT6 activation. We conclude that IL-4Rα signaling regulates macrophage functional polarization in a context-dependent manner. Pharmacological targeting of macrophage polarization therefore requires disease stage-specific treatment strategies. Research in Context: Alternative (M2-type macrophage activation through IL-4Rα promotes liver inflammation and fibrosis progression but speeds up fibrosis reversal. This demonstrates context dependent, opposing roles of M2-type macrophages. During reversal IL-4Rα induces fibrolytic MMPs, especially MMP-12, through STAT6. Liver-specific antisense oligonucleotides efficiently block IL-4Rα expression and attenuate fibrosis progression.

A devastating aspect of cancer cachexia is severe loss of muscle and fat mass. Though cachexia occurs in both sexes, it is not well-defined in the female. The Apc Min/+ mouse is genetically predisposed to develop intestinal tumors; circulating IL-6 is a critical regulator of cancer cachexia in the male Apc Min/+ mouse. The purpose of this study was to examine the relationship between IL-6 signaling and cachexia progression in the female Apc Min/+ mouse. Male and female Apc Min/+ mice were examined during the initiation and progression of cachexia. Another group of females had IL-6 overexpressed between 12-14 weeks or 15-18 weeks of age to determine whether IL-6 could induce cachexia. Cachectic female Apc Min/+ mice lost body weight, muscle mass, and fat mass; increased muscle IL-6 mRNA expression was associated with these changes, but circulating IL-6 levels were not. Circulating IL-6 levels did not correlate with downstream signaling in muscle in the female. Muscle IL-6r mRNA expression and SOCS3 mRNA expression as well as muscle IL-6r protein and STAT3 phosphorylation increased with severe cachexia in both sexes. Muscle SOCS3 protein increased in cachectic females but decreased in cachectic males. IL-6 overexpression did not affect cachexia progression in female Apc Min/+ mice. Our results indicate that female Apc Min/+ mice undergo cachexia progression that is at least initially IL-6-independent. Future studies in the female will need to determine mechanisms underlying regulation of IL-6 response and cachexia induction. PMID:25555992

The clinical forms of leprosy consist of a spectrum that reflects the host's immune response to the M. leprae; it provides an ideal model to study the host pathogen interaction and immunological dysregulation in humans. IL-10 and TGF-β producing Tregs are high in leprosy patients and responsible for immune suppression and M. leprae specific T cells anergy. In leprosy, involvement of IL-35 producing Tregs and Bregs remain unstudied. To study the role of IL-35 producing Tregs and Bregs in the human leprosy. Peripheral blood mononuclear cells from leprosy patients were isolated and stimulated with M. leprae antigen (MLCwA) for 48h. Intracellular cytokine IL-35 was evaluated in CD4 + CD25 + Tregs, CD19 + cells by FACS. Expression of PD-1 on CD4 + CD25 + Tregs, CD19 + cells and its ligand (PD-L1) on B cells, CD11c cells were evaluated by flow cytometry (FACS). Serum IL-35 level was estimated by ELISA. The frequency of IL-35 producing Tregs and Bregs cells were found to be high in leprosy patients (pleprosy patients. This study point out a shift in our understanding of the immunological features that mediate and regulate the immune suppression and the disease progression in leprosy patients with a new paradigm (IL-35 producing Tregs and Bregs) that is beyond TGF-β and IL-10 producing Treg cells.

Non-segmental vitiligo (NSV) results from autoimmune destruction of melanocytes. The altered levels of various cytokines have been proposed in the pathogenesis of vitiligo. However, the exact immune mechanisms have not yet been fully elucidated. To investigate the role of epidermal and systemic cytokines in active and stable NSV patients. Serum levels of inflammatory cytokines were checked in 42 active and 30 stable NSV patients with 30 controls. The lesional, perilesional and normal skin sections were subjected to H&E staining. The mRNA expression of inflammatory cytokines and their respective receptors were assessed by quantitative PCR in lesional skin of both active and stable NSV skin. The MITF and IL-17A were immunolocalized in lesional, perilesional and normal skin tissue. Significant increase in the expression of inflammatory cytokines, IL-17A, IL-1β and TGF-β was observed in active patients, whereas no change was observed in stable patients. A marked reduction in epidermal thickness was observed in lesional skin sections. Significant increase in IL-17A and significant decrease in microphthalmia associated transcription factor (MITF) expression was observed in lesional and perilesional skin sections. Moreover, qPCR analysis showed significant alterations in the mRNA levels of IL-17A, IL-1β, IFN-γ, TGF-β and their respective receptors in active and stable vitiligo patient samples. Increased levels of IL-17A and IL-1β cytokines and decreased expression of MITF suggested a possible role of these cytokines in dysregulation of melanocytic activity in the lesional skin and hence might be responsible for the progression of active vitiligo.

Full Text Available Purpose. To study the features of the progression of chronic hepatitis C in children with different variants of polymorphism of the gene IL-28B. Materials and methods. The study involved 57 children aged 3–18 years with CHC. All patients were involved in clinical, laboratory and instrumental examination. The stage of fibrosis was assessed morphologicallyon a scale METAVIR, by the calculation method — Fibro Test, on APRI index, and by the concentration of hyaluronic acid (HA, transforming growth factor TGF- β1 in serum usingIFA. The SNP genotypes of rs8099917 and rs12979860 lociin IL-28B were determinedby the method of the polymer chain reaction (PCR. A statistical analysis of the data was conducted. Resume. Most of the patients were children with chronic hepatitis C who had genotype CT at rs12979860 locus of the gene IL-28B (54% and the TT geno-type at rs8099917 locus (60%. It was found that fibrogenesis in the liver of patients with chronic hepatitis C depends on the polymorphism of the gene IL-28B. Unfavorable genotypevariants for the development of liver fibrosis are: TT (rs12979860, CT (rs12979860 and TG/GG (rs8099917. Variants CC (rs12979860 and TT (rs8099917 have a beneficial effect on the course of chronic hepatitis C, including patients with a lower stage of fibrosis. To determine the risk of progression of chronic hepatitis C it may be sufficient to determine the polymorphism of rs12979860locusin the gene IL-28B. Conclusions.The polymorphism variants CC (rs12979860 and TT (rs8099917of the gene IL-28Bare more favorable (lower severity of fibrosis in the progression of chronic hepatitis C in children. Variant TT (rs12979860 in the polymorphism of the gene IL-28B is associated with the progression of hepatitis — faster development of liver fibrosis.

Emerging evidence suggests that food insecurity is a significant public health concern among people who are homeless or marginally housed. The present study assessed prevalence of food insecurity and its covariates among a group of marginally housed individuals living in single-room occupancy (SRO) dwellings, a population for which there is little extant health or nutrition research. Cross-sectional survey incorporating the Household Food Insecurity Access Scale. Ten private SRO residences in the Uptown neighbourhood of Chicago, IL, USA, 2013. SRO residents over 18 years of age who were able to communicate verbally in English (n 153). Food insecurity was widespread among SRO residents, with 75 % of the sample considered food insecure and 52 % meeting criteria for severe food insecurity. Bivariate analyses indicated that female gender, eating most meals at a soup kitchen, having a mental health condition, problem drinking, having at least one chronic health condition, and diabetes were all significantly associated with food insecurity. In the multivariate ordered logistic regression model, eating most meals at a soup kitchen remained as the only significant correlate of food insecurity (OR=10·13). SRO residents and other marginally housed populations face unique food access challenges. Although targeted assistance in the form of food stamps and congregate meal programmes remains critical, efforts to prevent and address food insecurity among homeless and marginally housed individuals should include policy interventions that recognize poverty as the root cause of food insecurity and aim to increase overall income and improve housing conditions.

Little is known about the immunobiology of interleukin-17 (IL-17)-producing T cells and regulatory T cells (Treg) in chronic lymphocytic leukemia (CLL). In this study, the frequencies of Th17, Tc17, and CD39(+) Treg cells were enumerated in peripheral T cells isolated from 40 CLL patients and 15 normal subjects by flow cytometry. Our results showed a lower frequency of Th17 and Tc17 cells in progressive (0.99 ± 0.12 % of total CD3(+)CD4(+) cells; 0.44 ± 0.09 % of total CD8(+) cells) compared to indolent patients (1.57 ± 0.24 %, p = 0.042; 0.82 ± 0.2 %, p = 0.09) and normal subjects (1.78 ± 0.2 %, p = 0.003; 0.71 ± 0.09 %, p = 0.04). Decrease in IL-17-producing T cells was associated with CD39(+) Treg cells expansion. Variation of IL-17-producing cells and Treg cells in indolent and progressive patients was neither associated to the expression levels of Th1- and Th2-specific transcription factors T-bet and GATA-3 nor to the frequencies of IFN-γ and IL-4-producing CD4(+) T cells in a selected number of samples. Additionally, suppressive potential of CD4(+) Treg was similar in CLL patients and normal subjects. Our data indicate that progression of CLL is associated with downregulation of IL-17-producing T cells and expansion of Treg cells, implying contribution of these subsets of T cells in the progression of CLL.

Highlights: ► This study confirms the role of IL-7δ5 in breast cancer cell proliferation. ► IL-7δ5 promotes breast cancer cell proliferation and cell cycle progression. ► IL-7δ5 promotes cell proliferation via activation of PI3K/Akt pathway. -- Abstract: Various tumor cells express interleukin 7 (IL-7) and IL-7 variants. IL-7 has been confirmed to stimulate solid tumor cell proliferation. However, the effect of IL-7 variants on tumor cell proliferation remains unclear. In this study, we evaluated the role of IL-7δ5 (an IL-7 variant lacking exon 5) on proliferation and cell cycle progression of human MDA-MB-231 and MCF-7 breast cancer cells. The results showed that IL-7δ5 promoted cell proliferation and cell cycle progression from G1 phase to G2/M phase, associated with upregulation of cyclin D1 expression and the downregulation of p27 kip1 expression. Mechanistically, we found that IL-7δ5 induced the activation of Akt. Inhibition of PI3K/Akt pathway by LY294002 reversed the proliferation and cell cycle progression of MDA-MB-231 and MCF-7 cells induced by IL-7δ5. In conclusion, our findings demonstrate that IL-7δ5 variant induces human breast cancer cell proliferation and cell cycle progression via activation of PI3K/Akt pathway. Thus, IL-7δ5 may be a potential target for human breast cancer therapeutics intervention.

Atmospheric Mercury Transport Across Southern Lake Michigan: Influence from the Chicago/Gary Urban Area

Science.gov (United States)

Gratz, L. E.; Keeler, G. J.; Dvonch, J. T.

2008-12-01

The local and regional impacts of mercury emissions from major urban and industrial areas are critical to quantify in order to further understand mercury cycling in the environment. The Chicago/Gary urban area is one such location in which mercury emissions from industrial sources are significant and regional mercury transport needs to be further examined. Speciated atmospheric mercury was measured in Chicago, IL and Holland, MI from July to November 2007 to better characterize the impact of Chicago/Gary on southwest Michigan. Previous work under the 1994-1995 Lake Michigan Mass Balance Study (LMMBS) indicated that the highest levels of mercury deposition in southwest Michigan occurred with transport from the Chicago/Gary area, particularly with rapid transport where less mercury was deposited close to sources(1). However, at that time it was not possible to measure reactive gas phase mercury (RGM), a highly-soluble form of mercury in industrial emissions that is readily removed from the atmosphere. Since the LMMBS, the development of speciated mercury systems has made it possible to continuously monitor gaseous elemental mercury (Hg0), particulate mercury (HgP), and RGM. These measurements are useful for understanding atmospheric mercury chemistry and differentiating between local and regional source impacts due to the different behaviors of reactive and elemental mercury. Results from 2007 show that, on average, Hg0 and HgP were 1.5 times higher and RGM was 2 times higher in Chicago than in Holland. Mean mercury wet deposition was nearly 3 times higher in Chicago than in Holland. Meteorological analysis indicates that transport across the lake from Chicago/Gary occurred frequently during the study. Additional measurements of O3, SO2, meteorological parameters, event mercury and trace element precipitation samples, and modeled back-trajectories are used to discern regional transport events from local deposition and characterize the impact of the Chicago/Gary urban

Osteoarthritis guidelines: a progressive role for topical nonsteroidal anti-inflammatory drugs

Directory of Open Access Journals (Sweden)

Stanos SP

2013-04-01

Full Text Available Steven P Stanos Rehabilitation Institute of Chicago, Center for Pain Management, Chicago, IL, USA Abstract: Current treatment guidelines for the treatment of chronic pain associated with osteoarthritis reflect the collective clinical knowledge of international experts in weighing the benefits of pharmacologic therapy options while striving to minimize the negative effects associated with them. Consideration of disease progression, pattern of flares, level of functional impairment or disability, response to treatment, coexisting conditions such as cardiovascular disease or gastrointestinal disorders, and concomitant prescription medication use should be considered when creating a therapeutic plan for a patient with osteoarthritis. Although topical nonsteroidal anti-inflammatory drugs historically have not been prevalent in many of the guidelines for osteoarthritis treatment, recent evidence-based medicine and new guidelines now support their use as a viable option for the clinician seeking alternatives to typical oral formulations. This article provides a qualitative review of these treatment guidelines and the emerging role of topical nonsteroidal anti-inflammatory drugs as a therapy option for patients with localized symptoms of osteoarthritis who may be at risk for oral nonsteroidal anti-inflammatory drug-related serious adverse events.

Solar flux at sufficiently high concentrations to overcome threshold for the really important laser materials has not been available. This technological inhibition has recently been overcome through the application of nonimaging optics through the demonstration of concentration levels of 84,000 suns at the University of Chicago in a refractive medium (sapphire) and of over 20,000 suns in air at the Solar Energy Research Institute High Flux Facility. A thermodynamic overview is presented of solar lasers including solid state lasers and dye lasers.

John Dewey and early Chicago functionalism.

Science.gov (United States)

Backe, A

2001-11-01

John Dewey and James Angell are regarded respectively as the founder and systematizer of the Chicago school of functional psychology. The early Chicago school traditionally has been portrayed as a unified theoretical approach based primarily on William James's naturalist theory of mental processes. It is argued in this article that although the psychology systematized by Angell bore a close affinity to James's naturalism, Dewey's own psychology was based primarily on the neo-Hegelian philosophy of Thomas Hill Green. Through a review of a number of Dewey's major writings, Green's neo-Hegelian philosophy is shown to have influenced Dewey's views on psychological concepts such as reaction, emotion, and perception during the formative period of the Chicago school. The interpretation of Dewey's psychology developed in this article leads to the conclusion that early Chicago functionalism should not be regarded as a unified theoretical approach.

The innate immune system is the first line of defense against viruses by inducing expression of cytokines and chemokines. Many pandemic influenza H1N1 virus [P(H1N1)] infected severe cases occur in young adults under 18 years old who were rarely seriously affected by seasonal influenza. Results regarding host cytokine profiles of P(H1N1) are ambivalent. In the present study we investigated host cytokine profiles in P(H1N1) patients and identified cytokines related to disease severity. We retrieved 77, 59, 26 and 26 sera samples from P(H1N1) and non-flu influenza like illness (non-ILIs) cases with mild symptoms (mild patients), P(H1N1) vaccinees and healthy individuals, respectively. Nine and 16 sera were from hospitalized P(H1N1) and non-ILIs patients with severe symptoms (severe patients). Cytokines of IL-1, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12, IFN-γ and TNF-α were assayed by cytokine bead array, IL-17 and IL-23 measured with ELISA. Mild P(H1N1) patients produced significantly elevated IL-2, IL-12, IFN-γ, IL-6, TNF-α, IL-5, IL-10, IL-17 and IL-23 versus to healthy controls. While an overwhelming IL-6 and IL-10 production were observed in severe P(H1N1) patients. Higher IL-10 secretion in P(H1N1) vaccinees confirmed our observation that highly increased level of sera IL-6 and IL-10 in P(H1N1) patients may lead to disease progression. A comprehensive innate immune response was activated at the early stage of P(H1N1) infection with a combine Th1/Th2/Th3 cytokines production. As disease progression, a systemic production of IL-6 and IL-10 were observed in severe P(H1N1) patients. Further analysis found a strong correlation between IL-6 and IL-10 production in the severe P(H1N1) patients. IL-6 may be served as a mediator to induce IL-10 production. Highly elevated level of sera IL-6 and IL-10 in P(H1N1) patients may lead to disease progression, but the underlying mechanism awaits further detailed investigations.

The Berlin tradition in Chicago: Franz Alexander and the Chicago Institute for Psychoanalysis.

Science.gov (United States)

Schmidt, Erika S

2010-01-01

Freud considered Franz Alexander, the first graduate of the Berlin Psychoanalytic Institute and an assistant in the Berlin Polyclinic, to be "one of our strongest hopes for the future." Alexander went on to become the first director of the Chicago Institute for Psychoanalysis in 1932 and modeled some of the Chicago Institute's mission on his Berlin experiences. He was also a researcher in psychosomatic medicine, a prolific writer about psychoanalysis and prominent in psychoanalytic organizations. As he proposed modifications in psychoanalytic technique, he became a controversial figure, especially in the elaboration of his ideas about brief therapy and the corrective emotional experience. This paper puts Alexander's achievements in historical context, draws connections between the Berlin and Chicago Institutes and suggests that, despite his quarrels with traditional psychoanalysis, Alexander's legacy may be in his attitude towards psychoanalysis, characterized by a commitment to scientific study, a willingness to experiment, and a conviction about the role of psychoanalysis within the larger culture.

Objective: To explore the significance of changes of skin blister fluid NPY, IL-12, sICAM-1 and GM-CSF levels in patients with vitiligo in progressive stage. Methods: 80 patients with vitiligo in progressive stage were divided into two groups (vulgaris vitiligo groups : n=54, segmental vitiligo groups : n=26) Their blister fluid levels of NPY and GM-CSF were determined by radioimmunoassay(RIA), and IL-12 and sICAM-1 were determined by enzyme immunoassay. Results: The levels of skin blister fluid NPY were definitely higher in vitiliginous skin than those in non-vitiliginous patches in segmental vitiligo groups (P 0.05). The levels of skin blister fluid IL-12, sICAM-1 and GM-CSF were all obviously higher in vitiliginous skin than that in non-vitiliginous patches in vulgaris vitiligo groups (P 0.05). Conclusion: The changes of skin blister fluid NPY, IL-12, sICAM-1 and GM-CSF levels in vitiliginous skin may be closely related to development of difference type vitiligo patients with vitiligo, determination of 4 indexes might be helpful for studying the pathogenesis and clinical diagnosis of vitiligo.

Current diagnostic criteria require the language dysfunction to remain isolated for at least two years, and to remain the salient feature as the disease progresses, usually to involve other domains such as behavior, executive functions, and judgment. Although PPA in its early stages can usually be differentiated from probable Alzheimer’s disease (PRAD and the behavioral variant of frontotemporal lobar degeneration by the absence of significant changes in memory and behavior, and the preservation of activities daily living, progression of the disease often leads to deficits more consistent with the latter. Underlying etiologies remain heterogeneous: the neuropathological characteristics associated with frontotemporal lobar degeneration, cortocobasal degeneration, and motor neuron disease are usually found. There is a strong genetic susceptibility with affliction of first-degree relatives with similar disease in up to 40 to 50% in some series. Pathogenic mutations in genes coding for the proteins tau and progranulin have been isolated. These are leading to a better understanding of the neuropathological mechanisms and hopefully targeted disease-modifying therapy. Current therapy is limited to improving mood symptoms and targeting behavior changes as they develop. Referral to specialized centers where speech therapy, counseling, and education

The Dearborn Observatory, located on the Old University of Chicago campus from 1863 until 1888, was America's most promising astronomical facility when it was founded. Established by the Chicago Astronomical Society and directed by one of the country's most gifted astronomers, it boasted the largest telescope in the world and virtually unlimited operating funds. The Great Chicago Fire of 1871 destroyed its funding and demolished its research programme. Only via the sale of time signals and the heroic efforts of two amateur astronomers did the Dearborn Observatory survive.

ILs, as essential innate immune modulators, are involved in an array of biological processes. In the European rabbit (Oryctolagus cuniculus) IL-1α, IL-1β, IL-2, IL-4, IL-8, IL-10, IL-12A, IL-12B, IL-15 and IL-18 have been implicated in inflammatory processes and in the immune response against rabbit hemorrhagic disease virus and myxoma virus infections. In this study we characterized these ILs in six Lagomorpha species (European rabbit, pygmy rabbit, two cottontail rabbit species, European brown hare and American pika). Overall, these ILs are conserved between lagomorphs, including in their exon/intron structure. Most differences were observed between leporids and American pika. Indeed, when comparing both, some relevant differences were observed in American pika, such as the location of the stop codon in IL-1α and IL-2, the existence of a different transcript in IL8 and the number of cysteine residues in IL-1β. Changes at N-glycosylation motifs were also detected in IL-1, IL-10, IL-12B and IL-15. IL-1α is the protein that presents the highest evolutionary distances, which is in contrast to IL-12A where the distances between lagomorphs are the lowest. For all these ILs, sequences of human and European rabbit are more closely related than between human and mouse or European rabbit and mouse. PMID:26395994

Creating a marketplace for green roofs in Chicago

Vitt Sale, L.; Berkshire, M.

2004-01-01

Since 2003, the Chicago Department of Planning and Development has been encouraging city developers to consider installing green roofs on buildings in Chicago, with the belief that this practice results in mitigation of the urban heat island effect, cleaner runoff leaving green roofs, sound attenuation, aesthetic value, oxygen production, and mitigation of carbon dioxide emissions. However, the benefits to developers, which include reduced stormwater runoff, extended roof life and energy savings, in total do not offset the first cost premium of a green roof. Despite this, and with no mandate requiring green roofs, the marketplace is growing. After seeing green roofs on a tour in Europe, the mayor of Chicago encouraged the first design and installation of a 20,300 square foot demonstration green roof in Chicago, and other city-sponsored pilot projects followed shortly after. Since then, the number of green roofs in Chicago has grown to over one million square feet. A map of Chicago showing locations of most of the projects was presented. It was suggested that lower prices for green roofs, higher energy costs and an inclination to invest in long-term strategies would accelerate the market. In an effort to engage the public in dialogue, the Department of Planning and Development held seminars to promote the benefits of green roofs . Participants had many questions about the applicability of green roofs to Chicago, expressing skepticism that Chicago's climate would provide the same benefits as in Europe. Other concerns were expressed regarding the devaluation of property values resulting from placing green roofs on buildings; doubts about roof leaks; maintenance practices; and, bugs and mold. Since the first cost premium of the system remains a question, most participants expressed interest in some kind of incentive program, but remained open-minded if benefits could be proved. 6 figs

2005-01-01

This essay examines some historical questions and cultural constructions surrounding the song Sweet Home Chicago and its composer Robert Johnson. Noting that while the song has enjoyed long life, Johnson's lyric (describing Chicago as a land of California) has not, the essay critiques primitivist readings of Johnson while posing an African American cultural myth-Chicago as promised land of the Great Migration-as the subtext of his puzzling line. Finally, it considers whether mundane-sounding revisions of Johnson's lyric indicate a reduction in Chicago's mythic status, from safe haven to same old place.

Over the last decade, the management and prognosis of GISTs has changed dramatically with molecular characterization of the c-kit mutation and the adoption of targeted systemic therapy. Currently, the standard of care for resectable tumors is surgery, followed by adjuvant imatinib for tumors at high risk for recurrence. Inoperable or metastatic tumors are treated primarily with imatinib. Despite excellent initial response rates, resistance to targeted therapy has emerged as a common clinical problem, with relatively few therapeutic solutions. While the treatment of GISTs does not commonly include radiotherapy, radiation therapy could be a valuable contributing modality. Several case reports indicate that radiation can control locally progressive, drug-resistant disease. Further study is necessary to define whether radiation could potentially prevent or delay the onset of drug resistance, or improve outcomes when given in combination with imatinib.Keywords: GIST, imatinib, radiotherapy

Questions remain regarding the underlying pathophysiology and etiology of AOSD. Pathognomonic diagnostic tests and reliable biomarkers remain undiscovered. Over the past decade, important progress has been made. Diagnostic criteria employing glycosylated ferritin have improved specificity. More important, novel biologic therapies have offered important clues to AOSD's underlying pathophysiology. Cytokine-specific biologic therapies have been instrumental in providing more effective treatment for disease refractory to conventional treatment. While IL-1 therapy has demonstrated efficacy in refractory disease, novel therapies targeting IL-6 and IL-18 show great promise and are currently under investigation.

Diabetic nephropathy (DN) is a leading cause of chronic kidney disease (CKD). Interleukin-6 (IL-6) signaling participates in inflammation responses central to the progression of DN. Current evidence suggests that these IL-6 responses are mediated via gp130-STAT3 dependent mechanisms which, on one hand, trigger globally the transition from innate to adaptive immune response, and on the other hand act locally for tissue remodeling and immune cell infiltration. In diabetic conditions the role of IL-6 is not well elucidated. Both IL-6 classical signaling pathway via receptor IL-6R (IL-6R) and IL-6 trans-signaling pathway via soluble IL-6R (sIL-6R) were shown to participate in the pathogenesis and progression of DN, and IL-6 appears to influence renal cells also in an autocrine manner. To date, evidence is limited. The goal of this review is to provide an overview of our current understanding on the role of IL-6 signaling in DN and to delineate challenges for future research. Putative sequential events related to IL-6 secretion by different cell populations in diabetic conditions are outlined. Further, we discuss potential applications of anti-IL-6 therapy in the context of DN. Copyright © 2017 Elsevier Ltd. All rights reserved.

Etanercept is a fusion protein consisting of the soluble portion of the p75-tumor necrosis factor receptor (TNFR) and the Fc fragment of human IgG1, which is often used for the treatment of patients with rheumatoid arthritis. F8-IL10 is a human immunocytokine based on the F8 antibody and interleukin-10, which is currently being investigated in rheumatoid arthritis with promising clinical results. We have aimed at expressing murine versions of these two fusion proteins, in order to assess their pharmaceutical performance in the collagen-induced model of rheumatoid arthritis in the mouse. Two fusion proteins (termed muTNFR-Fc and F8-muIL10) were cloned, expressed in chinese hamster ovary (CHO) cells, purified and characterized. Biological activity of muTNFR-Fc was assessed by its ability to inhibit TNF-induced killing of mouse fibroblasts, while F8-muIL10 was characterized in terms of muIL10 activity, of binding affinity to the cognate antigen of F8, the alternatively-spliced EDA domain of fibronectin, by quantitative biodistribution analysis and in vivo imaging. The therapeutic activity of both fusion proteins was investigated in a collagen-induced mouse model of arthritis. Mouse plasma was analyzed for anti-drug antibody formation and cytokine levels were determined by bead-based multiplex technology. The association of F8-IL10 proteins with blood cells was studied in a centrifugation assay with radiolabeled protein. Both fusion proteins exhibited excellent purity and full biological activity in vitro. In addition, F8-muIL10 was able to localize on newly-formed blood vessels in vivo. When used in a murine model of arthritis, the two proteins inhibited arthritis progression. The activity of muTNFR-Fc was tested alone and in combination with F8-huIL10. The chimeric version of F8-IL10 was not better then the fully human fusion protein and showed similar generation of mouse anti-fusion protein antibodies.

Full Text Available Abstract Background Chorioamniotic membranes infection is a pathologic condition in which an abnormal secretion of proinflammatory cytokines halts fetal immune tolerance. The aim of the present study was to evaluate the functional response of human chorioamniotic membranes, as well as the individual contribution of the amnion and choriodecidua after stimulation with Escherichia coli, a pathogen associated with preterm labor. Methods Explants of chorioamniotic membranes from 10 women (37–40 weeks of gestation were mounted and cultured in a Transwell system, which allowed us to test the amnion and choriodecidua compartments independently. Escherichia coli (1 × 10 6 CFU/mL was added to either the amniotic or the choriodecidual regions or both; after a 24-h incubation, the secretion of IL-1beta, IL-6, TNFalpha, IL-8, and IL-10 in both compartments was measured using a specific ELISA. Data were analyzed by Kruskal-Wallis one-way analysis of variance. Results After stimulation with Escherichia coli, the choriodecidua compartment showed an increase in the secretion of IL-1beta (21-fold, IL-6 (2-fold, IL-8 (6-fold, and IL-10 (37-fold, regardless of which side of the membrane was stimulated; TNFalpha secretion augmented (22-fold also but only when the stimulus was applied simultaneously to both sides. When the amnion was stimulated directly, the level of IL-1beta (13-fold rose significantly; however, the increase in IL-8 secretion was larger (20-fold, regardless of the primary site of infection. TNFalpha secretion in the amnion compartment rose markedly only when Escherichia coli was simultaneously applied to both sides. Conclusion Selective stimulation of fetal membranes with Escherichia coli results in a differential production of IL-1beta, IL-6, TNFalpha, IL-8, and IL-10. These tissues were less responsive when the amnion side was stimulated. This is in agreement with the hypothesis that the choriodecidua may play a primary role during an ascending

The tumor microenvironment impacts tumor progression and individual cells, including CD4(+) T cells, which have been detected in bladder cancer tissues. The detailed mechanism of how these T cells were recruited to the bladder cancer tumor and their impact on bladder cancer progression, however, remains unclear. Using a human clinical bladder cancer sample survey and in vitro coculture system, we found that bladder cancer has a greater capacity to recruit T cells than surrounding normal bladder tissues. The consequences of higher levels of recruited T cells in bladder cancer included increased bladder cancer metastasis. Mechanism dissection revealed that infiltrating T cells might function through secreting the cytokine IL1, which increases the recruitment of T cells to bladder cancer and enhances the bladder cancer androgen receptor (AR) signaling that results in increased bladder cancer cell invasion via upregulation of hypoxia-inducible factor-1α (HIF1α)/VEGFa expression. Interruption of the IL1→AR→HIF1α→VEGFa signals with inhibitors of HIF1α or VEGFa partially reversed the enhanced bladder cancer cell invasion. Finally, in vivo mouse models of xenografted bladder cancer T24 cells with CD4(+) T cells confirmed in vitro coculture studies and concluded that infiltrating CD4(+) T cells can promote bladder cancer metastasis via modulation of the IL1→AR→HIF1α→VEGFa signaling. Future clinical trials using small molecules to target this newly identified signaling pathway may facilitate the development of new therapeutic approaches to better suppress bladder cancer metastasis.

Cellular senescence is a stable proliferative arrest state. Pituitary adenomas are frequent and mostly benign, but the mechanism for this remains unknown. IL-6 is involved in pituitary tumor progression and is produced by the tumoral cells. In a cell autonomous fashion, IL-6 participates in oncogene-induced senescence in transduced human melanocytes. Here we prove that autocrine IL-6 participates in pituitary tumor senescence. Endogenous IL-6 inhibition in somatotroph MtT/S shRNA stable clones results in decreased SA-β-gal activity and p16INK4a but increased pRb, proliferation and invasion. Nude mice injected with IL-6 silenced clones develop tumors contrary to MtT/S wild type that do not, demonstrating that clones that escape senescence are capable of becoming tumorigenic. When endogenous IL-6 is silenced, cell cultures derived from positive SA-β-gal human tumor samples decrease the expression of the senescence marker. Our results establish that IL-6 contributes to maintain senescence by its autocrine action, providing a natural model of IL-6 mediated benign adenoma senescence. PMID:27902467

HCV Specific IL-21 Producing T Cells but Not IL-17A Producing T Cells Are Associated with HCV Viral Control in HIV/HCV Coinfection.

Directory of Open Access Journals (Sweden)

Sonya A MacParland

Full Text Available Decreased hepatitis C virus (HCV clearance, faster cirrhosis progression and higher HCV RNA levels are associated with Human Immunodeficiency virus (HIV coinfection. The CD4+ T helper cytokines interleukin (IL-21 and IL-17A are associated with virus control and inflammation, respectively, both important in HCV and HIV disease progression. Here, we examined how antigen-specific production of these cytokines during HCV mono and HIV/HCV coinfection was associated with HCV virus control.We measured HCV-specific IL-21 and IL-17A production by transwell cytokine secretion assay in PBMCs from monoinfected and coinfected individuals. Viral control was determined by plasma HCV RNA levels.In acutely infected individuals, those able to establish transient/complete HCV viral control tended to have stronger HCV-specific IL-21-production than non-controllers. HCV-specific IL-21 production also correlated with HCV viral decline in acute infection. Significantly stronger HCV-specific IL-21 production was detected in HAART-treated coinfected individuals. HCV-specific IL-17A production was not associated with lower plasma HCV RNA levels in acute or chronic HCV infection and responses were stronger in HIV coinfection. HCV-specific IL-21/ IL-17A responses did not correlate with microbial translocation or fibrosis. Exogenous IL-21 treatment of HCV-specific CD8+ T cells from monoinfected individuals enhanced their function although CD8+ T cells from coinfected individuals were somewhat refractory to the effects of IL-21.These data show that HCV-specific IL-21 and IL-17A-producing T cells are induced in HIV/HCV coinfection. In early HIV/HCV coinfection, IL-21 may contribute to viral control, and may represent a novel tool to enhance acute HCV clearance in HIV/HCV coinfected individuals.

School Violent Crime and Academic Achievement in Chicago.

Educational outcomes vary dramatically across schools in the United States. Many under-performing schools, especially in Chicago, also deal with high levels of violent crime on school grounds. Exposure to this type of frequent violence may be an important factor shaping already disadvantaged students' educational experiences. However, estimating the effect of school violence on learning is difficult due to potential selection bias and the confounding of other school-level problems. Using detailed crime data from the Chicago Police Department, complete administrative records from the Chicago Public Schools, and school climate surveys conducted by the Consortium on Chicago School Research (2002-10), this study exploits variation in violent crime rates within schools over time to estimate its effect on academic achievement. School and neighborhood fixed-effects models show that violent crime rates have a negative effect on test scores, but not on grades. This effect is more likely related to direct reductions in learning, through cognitive stress and classroom disruptions, than changes in perceived safety, general school climate, or discipline practices.

Recent progress in host immunity to avian coccidiosis: IL-17 family cytokines as sentinels of the intestinal mucosa.

2013-11-01

The molecular and cellular mechanisms leading to immune protection against coccidiosis are complex and include multiple aspects of innate and adaptive immunities. Innate immunity is mediated by various subpopulations of immune cells that recognize pathogen associated molecular patterns (PAMPs) through their pattern recognition receptors (PRRs) leading to the secretion of soluble factors with diverse functions. Adaptive immunity, which is important in conferring protection against subsequent reinfections, involves subtypes of T and B lymphocytes that mediate antigen-specific immune responses. Recently, global gene expression microarray analysis has been used in an attempt to dissect this complex network of immune cells and molecules during avian coccidiosis. These new studies emphasized the uniqueness of the innate immune response to Eimeria infection, and directly led to the discovery of previously uncharacterized host genes and proteins whose expression levels were modulated following parasite infection. Among these is the IL-17 family of cytokines. This review highlights recent progress in IL-17 research in the context of host immunity to avian coccidiosis. Copyright © 2013.

Persistent infection with high-risk human papillomaviruses (HPV) causes epithelial hyperplasia that can progress to cancer and is thought to depend on immunosuppressive mechanisms that prevent viral clearance by the host. IL-17 is a cytokine with diverse functions in host defense and in the pathology of autoimmune disorders, chronic inflammatory diseases, and cancer. We analyzed biopsies from patients with HPV-associated cervical intraepithelial neoplasia grade 2/3 and murine skin displaying HPV16 E7 protein-induced epithelial hyperplasia, which closely models hyperplasia in chronic HPV lesions. Expression of IL-17 and IL-23, a major inducer of IL-17, was elevated in both human HPV-infected and murine E7-expressing lesions. Using a skin-grafting model, we demonstrated that IL-17 in HPV16 E7 transgenic skin grafts inhibited effective host immune responses against the graft. IL-17 was produced by CD3(+) T cells, predominantly CD4(+) T cells in human, and CD4(+) and γδ T cells in mouse hyperplastic lesions. IL-23 and IL-1β, but not IL-18, induced IL-17 production in E7 transgenic skin. Together, these findings demonstrate an immunosuppressive role for IL-17 in HPV-associated epithelial hyperplasia and suggest that blocking IL-17 in persistent viral infection may promote antiviral immunity and prevent progression to cancer.

Results of the 3-year Chicago Urban Forest Climate Project indicate that there are an estimated 50.8 million trees in the Chicago area of Cook and DuPage Counties; 66 percent of these trees rated in good or excellent condition. During 1991, trees in the Chicago area removed an estimated 6,145 tons of air pollutants, providing air cleansing valued at $9.2 million dollars. These trees also sequester approximately 155,000 tons of carbon per year, and provide residential heating and cooling energy savings that, in turn, reduce carbon emissions from power plants by about 12,600 tons annually. Shade, lower summer air temperatures, and a reduction in windspeed associated with increasing tree cover by 10 percent can lower total heating and cooling energy use by 5 to 10 percent annually ($50 to $90 per dwelling unit). The projected net present value of investment in planting and care of 95,000 trees in Chicago is $38 million ($402 per planted tree), indicating that the long-term benefits of trees are more than twice their costs

The industrial base of Chicago, and most Midwestern cities, continues to change. These changes are particularly visible in the manufacturing sector where the exodus of companies has left behind abandoned factories and industrial sites that now blight the urban landscape. As urban centers have seen a steady decline in their ability to attract and maintain their manufacturing base, great interest has been placed in seeing what can be done to attract economic activity back into the urban center. For most Midwestern cities, this often means trying to either replace or stem the tide of manufacturing facilities that have left the city for {open_quotes}greenfields{close_quotes} in suburban or rural locations or have simply moved overseas. On the replacement front, to compensate for the loss of manufacturing, some cities such as Chicago have managed to expand other areas of their economies, such as business services, finance, and tourism and recreation to maintain their vitality. This paper discusses three aspects of the changing economic landscape of Chicago and other Midwestern urban areas. First, some historical perspective will be provided on how Chicago came to be a manufacturing center and what factors since World War II have led manufacturing facilities to move away from the urban center. Second, the future prospects for manufacturing in the central city will be examined. Finally, what policies may help increase (or at the very least maintain) the concentration of manufacturing in Chicago will be discussed.

Full Text Available Background & objectives: Interleukin 4 (IL4 and IL13 genes are believed to be responsible for inflammation of the airways in asthmatics. These share a common receptor component called IL4Rα which is another potentially important candidate gene linked to asthma phenotypes. Another gene Toll-like receptor 4 (TLR4 might affect the incidence or progression of asthma through the expression of proinflammatory genes. Several single nucleotide polymorphisms (SNPs in IL4, IL13, IL4Rα and TLR4 have been reported to be linked to asthma or related phenotypes in several ethnic populations using linkage studies and association studies. However, the results have not been consistent. We investigated five SNPs (C-589T and C-33T of IL4, G+2044A of IL13, A+1902G of IL4Rα, and A+896G of TLR4 in patients with adult onset asthma to evaluate their role in manifestation and severity of asthma. Methods: Adult (>18 yr of age patients with asthma (n=100 and healthy controls (n=50 were included in the study. Genotyping was performed using sequenom MassARRAY technology. Results: The mutant alleles of the C-589T and C-33T SNPs in the promoter region of IL4 were present in 4 per cent patients with asthma but absent from the control group suggesting that the variations in IL4 may contribute to asthma occurrence. The SNPs of other genes were seen in both controls and patients. Interpretation & conclusions: The results suggest the possible association between the genetic distribution of C-589T and C-33T SNPs of IL4 with asthma in Indian adults.

Objective: To study the relationship between progress of the disease and the changes of serum IL-2, sIL-2R and TGF-β levels in patients with Graves' ophthalmopathy. Methods: Serum TGF-β(with RIA) and IL-2, sIL-2R(with ELISA) levels were determined in 30 patients with Graves' ophthalmopathy both before and after six months' treatment with prednisonlone as well as in 30 controls. Results: The serum IL-2 levels in the patients before treatment were significantly lower than those in controls (P 0.05). Both serum sIL-2R and TGF-β levels in the patients before treatment were significantly higher than those in controls (P<0.01). After treatment, the levels dropped markedly, but still remained significantly higher than those in controls (P<0.05 and P<0.01). Conclusion: Determination of changes of serum IL-2, sIL-2R and TGF-β levels in patients with Graves' ophthalmopathy might be helpful for outcome prediction. (authors)

Pulmonary fibrosis is a progressive and fatal disease that involves the remodeling of the distal airspace and the lung parenchyma, which results in compromised gas exchange. The median survival time once diagnosed is less than three years. Interleukin (IL)-13 has been shown to play a role in a number of inflammatory and fibrotic diseases. IL-13 modulates its effector functions via a complex receptor system that includes the IL-4 receptor (R) α, IL-13Rα1, and the IL-13Rα2. IL-13Rα1 binds IL-13 with low affinity, yet, when it forms a complex with IL-4α, it binds with much higher affinity, inducing the effector functions of IL-13. IL-13Rα2 binds IL-13 with high affinity but has a short cytoplasmic tail and has been shown to act as a nonsignaling decoy receptor. Transfection of fibroblasts and epithelial cells with IL-13Rα2 inhibited the IL-13 induction of soluble collagen, TGF-β, and CCL17. Adenoviral overexpression of IL-13Rα2 in the lung reduced bleomycin-induced fibrosis. Our work shows that overexpression of IL-13Rα2 inhibits the IL-13 induction of fibrotic markers in vitro and inhibits bleomycin-induced pulmonary fibrosis. In summary our study highlights the antifibrotic nature of IL-13Ra2. Copyright © 2015 the American Physiological Society.

IL6 induces TAM resistance via kinase-specific phosphorylation of ERα in OVCA cells.

About 40-60% of ovarian cancer (OVCA) cases express ERα, but only a small proportion of patients respond clinically to anti-estrogen treatment with estrogen receptor (ER) antagonist tamoxifen (TAM). The mechanism of TAM resistance in the course of OVCA progression remains unclear. However, IL6 plays a critical role in the development and progression of OVCA. Our recent results indicated that IL6 secreted by OVCA cells may promote the resistance of these cells to TAM via ER isoforms and steroid hormone receptor coactivator-1. Here we demonstrate that both exogenous (a relatively short period of treatment with recombinant IL6) and endogenous IL6 (generated as a result of transfection with a plasmid encoding sense IL6) increases expression of pERα-Ser118 and pERα-Ser167 in non-IL6-expressing A2780 cells, while deleting endogenous IL6 expression in IL6-overexpressing CAOV-3 cells (by transfection with a plasmid encoding antisense IL6) reduces expression of pERα-Ser118 and pERα-Ser167, indicating that IL6-induced TAM resistance may also be associated with increased expression of pERα-Ser118 and pERα-Ser167 in OVCA cells. Results of further investigation indicate that IL6 phosphorylates ERα at Ser118 and Ser167 by triggering activation of MEK/ERK and phosphotidylinositol 3 kinase/Akt signaling, respectively, to activate the ER pathway and thereby induce OVCA cells resistance to TAM. These results indicate that IL6 secreted by OVCA cells may also contribute to the refractoriness of these cells to TAM via the crosstalk between ER and IL6-mediated intracellular signal transduction cascades. Overexpression of IL6 not only plays an important role in OVCA progression but also promotes TAM resistance. Our results indicate that TAM-IL6-targeted adjunctive therapy may lead to a more effective intervention than TAM alone. © 2015 Society for Endocrinology.

Interleukin-30: A novel microenvironmental hallmark of prostate cancer progression.

Science.gov (United States)

Di Carlo, Emma

2014-01-01

Metastatic prostate cancer is a leading cause of cancer-related death in men worldwide. We have recently discovered that IL-30 shapes the microenvironment of prostate cancer and tumor-draining lymph nodes to favor tumor progression. IL-30 supports tumor growth in vitro, and IL-30 expression in prostate cancer patients is associated with high tumor grade and metastatic stage of disease. Thus, IL-30 may constitute a valuable target for modern therapeutic approaches to hamper prostate cancer progression.

A model of the relations between psychological factors and cancer progression should include brain and systemic components and their link with critical cellular stages in cancer progression. We present a psychoneuroimmunological (PNI) model that links helplessness-hopelessness (HH) with cancer progression via interleukin-1beta (IL-1beta). IL-1beta was elevated in the brain following exposure to inescapable shock, and HH was minimized by antagonizing cerebral IL-1beta. Elevated cerebral IL-1beta increased cancer metastasis in animals. Inescapable shock was associated with systemic elevations of IL-1beta and peripheral IL-1beta was associated with escape from apoptosis, angiogenesis, and metastasis. Involvement of the sympathetic nervous system and the hypothalamic-pituitary-adrenal axis are discussed. Future studies need to identify the role of additional factors in this PNI pathway.

Cytokine members of the IL-12 family have attracted enormous attention in the last few years, with IL-35 being the one of the most attractive-suppressive cytokine. IL-35 is an important mediator of regulatory T cell function. Regulatory T cells play key roles in restoring immune homeostasis after facing challenges such as infection by specific pathogens. Moreover, a crucial role for regulatory T cell populations has been demonstrated in several physiological processes, including establishment of fetal-maternal tolerance, maintenance of self-tolerance and prevention of autoimmune diseases. However, a deleterious involvement of immune regulatory T cells has been documented in specific inhibition of immune responses against tumor cells, promotion of chronic infections and establishment of chronic inflammatory disorders. In this review, we attempt to shed light on the concept of immune-homoeostasis on the aforementioned issues, taking IL-35 as the hallmark of regulatory responses. The dilemma between immune-mediated cancer treatment and inflammation is discussed. Histopathological indications of chronic vs. acute infections are elaborated. Moreover, the evidence that IL-35 requires additional immune-regulatory cytokines, such as IL-10 and TGF-β, to induce effective and maximal anti-inflammatory effects suggest that immune-regulation requires multi-factorial analysis of many immune playmakers rather than a specific immune target. © 2018 UICC.

Diabetic foot ulcers (DFU) are one of the major complications in type II diabetes patients and can result in amputation and morbidity. Although multiple approaches are used clinically to help wound closure, many patients still lack adequate treatment. Here we show that IL-20 subfamily cytokines are upregulated during normal wound healing. While there is a redundant role for each individual cytokine in this subfamily in wound healing, mice deficient in IL-22R, the common receptor chain for IL-20, IL-22, and IL-24, display a significant delay in wound healing. Furthermore, IL-20, IL-22 and IL-24 are all able to promote wound healing in type II diabetic db/db mice. Mechanistically, when compared to other growth factors such as VEGF and PDGF that accelerate wound healing in this model, IL-22 uniquely induced genes involved in reepithelialization, tissue remodeling and innate host defense mechanisms from wounded skin. Interestingly, IL-22 treatment showed superior efficacy compared to PDGF or VEGF in an infectious diabetic wound model. Taken together, our data suggest that IL-20 subfamily cytokines, particularly IL-20, IL-22, and IL-24, might provide therapeutic benefit for patients with DFU.

We have investigated the importance of interleukin-6 (IL-6) in promoting tumor growth and metastasis. In human primary breast cancers, increased levels of IL-6 were found at the tumor leading edge and positively correlated with advanced stage, suggesting a mechanistic link between tumor cell production of IL-6 and invasion. In support of this hypothesis, we showed that the IL-6/Janus kinase (JAK)/signal transducer and activator of transcription 3 (Stat3) pathway drives tumor progression through the stroma and metastatic niche. Overexpression of IL-6 in tumor cell lines promoted myeloid cell recruitment, angiogenesis, and induced metastases. We demonstrated the therapeutic potential of interrupting this pathway with IL-6 receptor blockade or by inhibiting its downstream effectors JAK1/2 or Stat3. These clinically relevant interventions did not inhibit tumor cell proliferation in vitro but had profound effects in vivo on tumor progression, interfering broadly with tumor-supportive stromal functions, including angiogenesis, fibroblast infiltration, and myeloid suppressor cell recruitment in both the tumor and pre-metastatic niche. This study provides the first evidence for IL-6 expression at the leading edge of invasive human breast tumors and demonstrates mechanistically that IL-6/JAK/Stat3 signaling plays a critical and pharmacologically targetable role in orchestrating the composition of the tumor microenvironment that promotes growth, invasion, and metastasis.

Biological significance of soluble IL-2 receptor

Directory of Open Access Journals (Sweden)

Calogero Caruso

1993-01-01

Full Text Available A NUMBER of receptors for growth factors and differentiation antigens have been found to be secreted or released by cells. Following mononuclear cell (MNC activation and interleukin-2 receptor (IL-2R expression, a soluble form of the Alpha;-chain of IL-2R (sIL-2R is released. The sIL-2R has been shown to be present in the culture supernatants of activated MNCs as well as in normal sera and, in higher amounts, in sera from subjects affected by several diseases including neoplastic, infectious and autoimmune ones, and in sera from transplanted patients suffering allograft rejection. The blood sIL-2R levels depend on the number of producing cells and the number of molecules per cell, so that sIL-2R blood values may represent an index of the number and the functional state of producing cells, both normal and neoplastic. Thus, monitoring of the immune system, mostly T-cells and haematological malignancies might be targets for the measurement of sIL-2R. Since many conditions may influence sIL-2R production, little diagnostic use may result from these measurements. However, since blood sIL-2R levels may correlate with disease progression and/or response to therapy, their measurement may be a useful index of activity and extent of disease. The precise biological role of the soluble form of the IL-2R is still a matter of debate. However, we know that increased sIL-2R levels may be observed in association with several immunological abnormalities and that sIL-2R is able to bind IL-2. It is conceivable then that in these conditions the excess sIL-2R released in vivo by activated lymphoid cells or by neoplastic cells may somehow regulate IL-2-dependent processes. On the other hand, it cannot exclude that sIL-2R is a by-product without biological significance. Finally, it is puzzling that in many conditions in which an increase of blood sIL-2R values has been observed, MNCs display a decreased in vitro capacity to produce sIL-2R. These seemingly contrasting

In a subset of severe asthma patients, chronic airway inflammation is associated with infiltration of neutrophils, Th-17 cells and elevated expression of Th-17-derived cytokines (e.g., interleukin [IL]-17, IL-21, IL-22). Peripheral neutrophils from allergic asthmatics are known to express higher IL-17 cytokine levels than those from healthy subjects, but the regulatory mechanisms involved are not well understood. We hypothesize that Th-17 regulatory cytokines could modulate IL-17 expression in neutrophils. Peripheral blood neutrophils isolated from asthmatics were stimulated with IL-21, IL-23, and IL-6 cytokines and their ability to produce IL-17A and IL-17F was determined relative to healthy controls. Signal transducer and activator of transcription 3 (STAT3) phosphorylation levels were measured in stimulated neutrophil using flow cytometry. The requirement for STAT3 phosphorylation was determined by blocking its activation using a specific chemical inhibitor. Stimulating asthmatic neutrophils with IL-21, 23, and 6 enhanced the production of IL-17A and IL-17F at significantly higher levels comparatively to healthy controls. Stimulating neutrophils with IL-21, IL-23, and IL-6 cytokines enhanced STAT3 phosphorylation, in all cases. Interestingly, inhibiting STAT3 phosphorylation using a specific chemical inhibitor dramatically blocked the ability of neutrophils to produce IL-17, demonstrating that STAT3 activation is the major factor mediating IL-17 gene expression. These findings suggest that neutrophil infiltration in lungs of severe asthmatics may represent an important source of pro-inflammatory IL-17A and -F cytokines, a production enhanced by Th-17 regulatory cytokines, and thus providing a feedback mechanism that sustains inflammation. Our results suggest that STAT3 pathway could be a potential target for regulating neutrophilic inflammation during severe asthma.

Full Text Available Stigma regarding viral hepatitis and liver disease has psychological and social consequences including causing negative self-image, disrupting relationships, and providing a barrier to prevention, testing, and treatment. The aim of this study was to characterize and compare HBV knowledge and stigma in Vietnamese in Ho Chi Minh City and Chicago and to begin to evaluate the cultural context of HBV stigma. Methods. A written survey including knowledge questions and a validated HBV stigma questionnaire was distributed to Vietnamese in Ho Chi Minh City and Chicago. 842 surveys from Ho Chi Minh City and 170 from Chicago were analyzed. Results. Vietnamese living in Chicago had better understanding of HBV transmission and that HBV can cause chronic infection and liver cancer. Vietnamese in Chicago had higher stigma scores on a broad range of items including guilt and shame about HBV and were more likely to feel that persons with HBV can bring harm to others and should be isolated. Conclusions. Vietnamese in Ho Chi Minh City and Chicago have knowledge deficits about HBV, particularly regarding modes of transmission. Persons in Ho Chi Minh City expressed lower levels of HBV stigma than Vietnamese living in Chicago, likely reflecting changing cultural attitudes in Vietnam. Culturally appropriate educational initiatives are needed to address the problem of HBV stigma.

IL-6/IL-12 Cytokine Receptor Shuffling of Extra- and Intracellular Domains Reveals Canonical STAT Activation via Synthetic IL-35 and IL-39 Signaling.

IL-35 and IL-39 are recently discovered shared members of the IL-6- and IL-12-type cytokine family with immune-suppressive capacity. IL-35 has been reported to induce the formation of four different receptor complexes: gp130:IL-12β2, gp130:gp130, IL-12β2:IL-12β2, and IL-12β2:WSX-1. IL-39 was proposed to form a gp130:IL-23R receptor complex. IL-35, but not IL-39, has been reported to activate non-conventional STAT signaling, depending on the receptor complex and target cell. Analyses of IL-35 and IL-39 are, however, hampered by the lack of biologically active recombinant IL-35 and IL-39 proteins. Therefore, we engineered chimeric cytokine receptors to accomplish synthetic IL-35 and IL- 39 signaling by shuffling the extra- and intracellular domains of IL-6/IL-12-type cytokine receptors, resulting in biological activity for all previously described IL-35 receptor complexes. Moreover, we found that the proposed IL-39 receptor complex is biologically active and discovered two additional biologically active synthetic receptor combinations, gp130/IL-12Rβ1 and IL-23R/IL-12Rβ2. Surprisingly, synthetic IL-35 activation led to more canonical STAT signaling of all receptor complexes. In summary, our receptor shuffling approach highlights an interchangeable, modular domain structure among IL-6- and IL-12-type cytokine receptors and enabled synthetic IL-35 and IL-39 signaling.

Full Text Available This paper traces the evolvement of monetary-policy proposals at Chicago from the early 1930s up until the appearance of Friedman’s classic “Restatement” of the quantity theory in 1956. First, the pragmatic nature of Chicagoan monetary economics during the depression-dominated 1930s is examined. The emergence of the Chicagoan affirmation in the efficiency of traditional monetary policy is then described. It is argued that rather than representing a transmogrification of the monetary views of his predecessors, Friedman’s “Restatement” more accurately reflects a culmination of post-Keynesian Chicago contributions on money. In addition, the interpretation of budget deficits financed by money creation as the implementation of monetary, as opposed to fiscal, policy is shown to be a common link among Chicagoans throughout the entire period under consideration.

IL-1Ra (recombinant human IL-1 receptor antagonist in the treatment of rheumatoid arthritis: the efficacy

2011-09-01

Full Text Available Interleukin 1 receptor antagonist (IL-1Ra is a naturally occurring IL-1 inhibitor, acting as a “receptor antagonist”, which blocks IL-1 mediated signal transduction. In 1990 IL-1Ra was cloned and later on, a large numbers of studies led to disclosure of the crucial importance of the imbalance between IL-1 and IL-1Ra in the pathogenesis of rheumatoid arthritis (RA. In 1991, almost 8 years after the initial isolation of IL-1, recombinant IL-1Ra (IL-1ra, Kineret was introduced in clinical trials involving patients with RA. Between 2001 and 2002 IL-1ra was approved by the US Food and Drug Administration and by the European Agency for the Evaluation of the Medicinal Products and in 2003 it was registered in Italy, too. In RA recombinant IL-1ra has been evaluated in 5 randomized, placebo-controlled clinical trials involving more than 2900 patients. Two of the trials involved the use of IL-1ra as monotherapy versus placebo and two trials in combination with methotrexate (MTX; the last trial explored the use of a fixed 100 mg/day IL-1ra dosage in a RA patient population including a wide array of co-morbid conditions as well as concomitant medications. The studies confirmed both the efficacy and the safety of IL-1ra in patients with active and severe RA. 43% of patients receiving 150 mg/day IL-1ra achieved a 20% response according to the American College of Rheumatology criteria (ACR20, compared to 27% in the placebo group. In the MTX combination therapy study, 42% of the patients receiving 1 mg/Kg/day of IL-1ra achieved an ACR20, 24% an ACR50 and 10% an ACR70. In each study, significant improvements in the Health Assessment Questionnaire scores (HAQ were observed. There were rapid gains in the number of days at work or domestic activity in the treated patients, and the increases in productivity were dose related. At early 24 weeks, there was significant reduction of both the score for progression of joint space narrowing (JSN and the Total modified

High resolution esophageal manometry (HREM) has been interpreted all along by visual interpretation of color plots until the recent introduction of Chicago classification which categorises HREM using objective measurements. It compares HREM diagnosis of esophageal motor disorders by visual interpretation and Chicago classification. Using software Trace 1.2v, 77 consecutive tracings diagnosed by visual interpretation were re-analyzed by Chicago classification and findings compared for concordance between the two systems of interpretation. Kappa agreement rate between the two observations was determined. There were 57 males (74 %) and cohort median age was 41 years (range: 14-83 years). Majority of the referrals were for gastroesophageal reflux disease, dysphagia and achalasia. By "intuitive" visual interpretation, the tracing were reported as normal in 45 (58.4 %), achalasia 14 (18.2 %), ineffective esophageal motility 3 (3.9 %), nutcracker esophagus 11 (14.3 %) and nonspecific motility changes 4 (5.2 %). By Chicago classification, there was 100 % agreement (Kappa 1) for achalasia (type 1: 9; type 2: 5) and ineffective esophageal motility ("failed peristalsis" on visual interpretation). Normal esophageal motility, nutcracker esophagus and nonspecific motility disorder on visual interpretation were reclassified as rapid contraction and esophagogastric junction (EGJ) outflow obstruction by Chicago classification. Chicago classification identified distinct clinical phenotypes including EGJ outflow obstruction not identified by visual interpretation. A significant number of unclassified HREM by visual interpretation were also classified by it.

Co-immunotherapy with interleukin-2 and taurolidine for progressive metastatic melanoma.

LENUS (Irish Health Repository)

O'Brien, G C

2012-02-03

BACKGROUND: Recombinant interleukin-2(rIL-2) therapy in metastatic melanoma is limited by toxicities, particularly vascular leak syndrome(VLS). Taurolidine potentiates the anti-neoplastic effects of IL-2 while reducing its associated endothelial cell dysfunction in experimental settings. We hypothesized that co-administration of rIL-2 with taurolidine could enhance tolerability without weakening effectiveness. METHODS: Eleven patients with progressive metastatic melanoma received high-dose rIL-2 with co-infusion of taurolidine. Patients were monitored for the development of toxicities and evidence of response. RESULTS: Ten patients tolerated twenty-nine courses of high-dose rIL-2 without dose-reduction. Most toxicities were low-grade. No patient developed VLS. Seven patients died from disease progression. Two had complete clinical and radiological responses to treatment. Two patients remain alive despite evidence of disease progression a mean of 17.5 months after diagnosing metastatic disease. CONCLUSION: Co-administration of taurolidine with high-dose rIL-2 in stage IV melanoma patients appears to greatly enhance the tolerability of this regime without diminishing its therapeutic value.

It has been suggested that interleukin (IL)-18 plays a role in the development of inflammatory and fibrosing lung diseases. Associations of polymorphisms in the genes coding for IL-18 (108 /G-656T, C-607A, G-137C, T113G, C127T) and its receptor (IL8R1/C-69T) with coal workers' pneumoconiosis (CWP) were studied in 200 miners who were examined in 1990, 1994 and 1999. Coal-dust exposure was assessed according to job history and ambient measures. The main health outcome was lung computed tomography (CT) score in 1990. Internal coherence was assessed by studying CT score in 1994, 4-yr change in CT score and CWP incidence and prevalence. CT score in 1990 was a good predictor of radiographic grade in 1999 and, therefore, an appropriate subclinical quantitative trait. The IL18 -137C allele was associated with lower CT score in 1990 and 1994 (11.24 versus 1.69 and 1.57 versus 2.46, respectively), slower progression of CT score between 1990 and 1994 and lower pneumoconiosis prevalence in 1999 relative to the G allele (0.33 versus 0.77 and 8.2 versus 19.6%, respectively). Smoking- or dust-adjustment, and stratification on IL18R1 genotype and adjustment for haplotype effects did not change the conclusions. In conclusion, the results of the present study suggest a role for IL18 in reducing the development of this fibrosing lung disease.

Tumor epithelial cells develop within a microenvironment consisting of extracellular matrix, growth factors, and cytokines produced by nonepithelial stromal cells. In response to paracrine signals from tumor epithelia, stromal cells modify the microenvironment to promote tumor growth and metastasis. Here, we identify interleukin 33 (IL-33) as a regulator of tumor stromal cell activation and mediator of intestinal polyposis. In human colorectal cancer, IL-33 expression was induced in the tumor epithelium of adenomas and carcinomas, and expression of the IL-33 receptor, IL1RL1 (also referred to as IL1-R4 or ST2), localized predominantly to the stroma of adenoma and both the stroma and epithelium of carcinoma. Genetic and antibody abrogation of responsiveness to IL-33 in the Apc(Min/+) mouse model of intestinal tumorigenesis inhibited proliferation, induced apoptosis, and suppressed angiogenesis in adenomatous polyps, which reduced both tumor number and size. Similar to human adenomas, IL-33 expression localized to tumor epithelial cells and expression of IL1RL1 associated with two stromal cell types, subepithelial myofibroblasts and mast cells, in Apc(Min/+) polyps. In vitro, IL-33 stimulation of human subepithelial myofibroblasts induced the expression of extracellular matrix components and growth factors associated with intestinal tumor progression. IL-33 deficiency reduced mast cell accumulation in Apc(Min/+) polyps and suppressed the expression of mast cell-derived proteases and cytokines known to promote polyposis. Based on these findings, we propose that IL-33 derived from the tumor epithelium promotes polyposis through the coordinated activation of stromal cells and the formation of a protumorigenic microenvironment.

The Chicago Classification defines esophageal motility disorders in high resolution manometry. This is based on individual scoring of 10 swallows performed in supine position. Disorders of esophago-gastric junction (EGJ) outflow obstruction are defined by a median integrated relaxation pressure above the limit of normal and divided into 3 achalasia subtypes and EGJ outflow obstruction. Major motility disorders (aperistalsis, distal esophageal spasm, and hypercontractile esophagus) are patterns not encountered in controls in the context of normal EGJ relaxation. Finally with the latest version of the Chicago Classification, only two minor motor disorders are considered: ineffective esophageal motility and fragmented peristalsis.

Susceptible genotypes to periodontal disease are associated with disease onset and progression. The aim of this study was to examine the effect of gene polymorphisms on the risk of further disease progression and the need for further treatment among adults with chronic periodontal disease. Sixty-seven patients diagnosed with chronic periodontitis were grouped according to genotype status and risk of further progression of disease and tooth loss. All individuals were clinically evaluated for probing pocket depth, clinical attachment loss and bleeding on probing at baseline and 45 days after treatment. Blood samples were collected at baseline and genotyping of the polymorphisms in IL-6 (rs1800796) and IL-10 (rs1800872) genes were performed by PCR. Following DNA separation and genotyping, 65.7% of the patients were homozygous carriers of the IL-6 -572G and 49.3% were carriers of the IL-10 -592A allele. Individuals at risk of disease progression ranged from 7.5% to 62.7% based on the criteria used. Carriers of the IL-10 -592A allele were significantly associated with BOP ≥ 30% and therefore exhibited a higher risk of further periodontal breakdown (p = 0.018) with an odds ratio of 1.18. None of the other definitions of disease progression were significantly associated with the examined IL-6 and IL-10 genotypes (p > 0.05). IL-10 polymorphism was associated with an increased risk of further disease progression and the potential need for further treatment following non-surgical periodontal treatment. Susceptible IL-6 genotypes were not associated with the risk of persisting or recurrent disease activity.

IL17/IL17RA as a Novel Signaling Axis Driving Mesenchymal Stem Cell Therapeutic Function in Experimental Autoimmune Encephalomyelitis

Directory of Open Access Journals (Sweden)

Mónica Kurte

2018-04-01

Full Text Available The therapeutic effect of mesenchymal stem cells (MSCs in multiple sclerosis (MS and the experimental autoimmune encephalomyelitis (EAE model has been well described. This effect is, in part, mediated through the inhibition of IL17-producing cells and the generation of regulatory T cells. While proinflammatory cytokines such as IFNγ, TNFα, and IL1β have been shown to enhance MSCs immunosuppressive function, the role of IL17 remains poorly elucidated. The aim of this study was, therefore, to investigate the role of the IL17/IL17R pathway on MSCs immunoregulatory effects focusing on Th17 cell generation in vitro and on Th17-mediated EAE pathogenesis in vivo. In vitro, we showed that the immunosuppressive effect of MSCs on Th17 cell proliferation and differentiation is partially dependent on IL17RA expression. This was associated with a reduced expression level of MSCs immunosuppressive mediators such as VCAM1, ICAM1, and PD-L1 in IL17RA−/− MSCs as compared to wild-type (WT MSCs. In the EAE model, we demonstrated that while WT MSCs significantly reduced the clinical scores of the disease, IL17RA−/− MSCs injected mice exhibited a clinical worsening of the disease. The disability of IL17RA−/− MSCs to reduce the progression of the disease paralleled the inability of these cells to reduce the frequency of Th17 cells in the draining lymph node of the mice as compared to WT MSCs. Moreover, we showed that the therapeutic effect of MSCs was correlated with the generation of classical Treg bearing the CD4+CD25+Foxp3+ signature in an IL17RA-dependent manner. Our findings reveal a novel role of IL17RA on MSCs immunosuppressive and therapeutic potential in EAE and suggest that the modulation of IL17RA in MSCs could represent a novel method to enhance their therapeutic effect in MS.

The cytokine interleukin 1 (IL 1) plays an important role in the induction of IL 2 secretion and high-affinity IL 2 receptor (IL 2R) expression by T cells. The events that follow binding of IL 1 to IL 1R, however, are still unknown. In this study we describe two variants of the murine thymoma EL4 (5D3 and D6/76) that express comparable numbers of cell surface IL 1 receptors and bind IL 1 with the same affinity, but show distinct IL 1-dependent IL 2 secretion and IL 2R expression.

International Nuclear Information System (INIS)

Snyder, T.L.; Keffer, J.W.

1992-01-01

The Chicago section of the American Nuclear Society (ANS) is an active organization with ∼450 members. The local section territory encompasses northern Illinois and includes in its territory all six of Commonwealth Edison Company's (CECo's) nuclear generating stations as well as Argonne National Laboratory (ANL). Included in the territory are several large engineering firms - ABB Impell, Bechtel, Fluor Daniel, and Sargent ampersand Lundy. The national headquarters of the ANS is also located within the local section boundaries. All these organizations are represented in the local section membership and provide access to abundant technical resources that can be used to enhance public acceptance of nuclear power. An important attribute of any local section that enables it to perform interesting programs and be active in the community is its financial resources. The Chicago section has a strong financial base because of its ability to raise funds by participating in and sponsoring ANS topical and other meetings. For instance, in 1991, they sponsored and were actively involved in the Emergency Preparedness Topical Meeting held in Chicago. In 1992, they were actively involved in sponsoring the organizational activities of the ANS/ENS International Meeting, which will celebrate the 50th year of nuclear fission. The financial and technical resources of the Chicago section continue to contribute to a successful program of public education and public acceptance activities regarding the nuclear industry

Salivary Levels of IL-6 and IL-17 Could Be an Indicator of Disease Severity in Patients with Calculus Associated Chronic Periodontitis

Directory of Open Access Journals (Sweden)

Husniah Batool

2018-01-01

Full Text Available Background/Purpose. Chronic periodontitis is an inflammatory disease of gums that causes loss of supporting structures of teeth, that is, gingiva, periodontal ligament, cementum, and alveolar bone. Levels of various cytokines in the serum, gingival tissues, and gingival crevicular fluid in patients with chronic periodontitis have been studied, but limited data are available on the level of cytokines in saliva. Therefore, a study was designed to determine levels of salivary IL-6 and IL-17 in patients with calculus associated chronic periodontitis. Materials and Methods. It was a comparative, cross-sectional study that is comprised of 41 healthy controls and 41 calculus associated chronic periodontitis patients (CP patients. According to the degree of attachment loss, CP patients were subcategorized as mild (CAL 1-2 mm, moderate (CAL 3-4 mm, and severe (CAL > 5 mm forms of periodontitis. Salivary levels of IL-6 and IL-17 were determined using enzyme-linked immunosorbent assay (ELISA technique. Data was analyzed using SPSS 20.0. Results. Between healthy controls and CP patients (moderate and severe disease, a statistically significant difference was observed in the concentrations of IL-6 and IL-17. In CP patients, the highest mean ± SD of salivary IL-6 and IL-17 was observed in severe CP, followed by moderate and mild CP. Regarding level of IL-6, a statistically significant difference was observed between mild and severe disease and between moderate and severe subcategories of CP patients. Similarly, statistically significant difference was observed in the level of IL-17 between mild and moderate, mild and severe disease, and moderate and severe disease. Conclusion. The levels of salivary IL-6 and IL-17 were increased significantly in calculus associated CP patients as compared to healthy controls and these levels increased with the progression of CP. Clinical Significance. Salivary levels of IL-6 and IL-17 may help in the subcategorization

Kline, Wendy

This article analyzes the role of doctors and activists in Chicago who successfully redefined the practice and politics of childbirth both locally and ultimately nationwide. It begins with the story of Joseph DeLee's Chicago Maternity Center, responsible for supervising over 100,000 home births between 1932 and 1972. Most of the mothers cared for by the Center were nonwhite, poor, and had little or no access to prenatal care, yet their babies had a far higher survival rate than the nationwide average. Thousands of medical students from all over the Midwest experienced their first deliveries not in hospitals, but in these homes. The article then addresses a very different demographic: a rising number of middle-class white families in the suburbs of Chicago who, beginning in the 1950s, opted for out-of-hospital births. Many of them learned about home birth through their involvement in La Leche League, the breastfeeding organization formed in a Chicago suburb in 1956. Seemingly separated by class, race, and locale, the link between these two groups of home birthers was the philosophy and training in place at the Chicago Maternity Center. © The Author 2017.

Chicago's water market: Dynamics of demand, prices and scarcity rents

Science.gov (United States)

Ipe, V.C.; Bhagwat, S.B.

2002-01-01

Chicago and its suburbs are experiencing an increasing demand for water from a growing population and economy and may experience water scarcity in the near future. The Chicago metropolitan area has nearly depleted its groundwater resources to a point where interstate conflicts with Wisconsin could accompany an increased reliance on those sources. Further, the withdrawals from Lake Michigan is limited by the Supreme Court decree. The growing demand and indications of possible scarcity suggest a need to reexamine the pricing policies and the dynamics of demand. The study analyses the demand for water and develops estimates of scarcity rents for water in Chicago. The price and income elasticities computed at the means are -0.002 and 0.0002 respectively. The estimated scarcity rents ranges from $0.98 to $1.17 per thousand gallons. The results indicate that the current prices do not fully account for the scarcity rents and suggest a current rate with in the range $1.53 to $1.72 per thousand gallons.

IFN-γ, IL-4 and IL-13 modulate responsiveness of human airway smooth muscle cells to IL-13

Directory of Open Access Journals (Sweden)

Michoud Marie-Claire

2008-12-01

Full Text Available Abstract Background IL-13 is a critical mediator of allergic asthma and associated airway hyperresponsiveness. IL-13 acts through a receptor complex comprised of IL-13Rα1 and IL-4Rα subunits with subsequent activation of signal transducer and activator of transcription 6 (STAT6. The IL-13Rα2 receptor may act as a decoy receptor. In human airway smooth muscle (HASM cells, IL-13 enhances cellular proliferation, calcium responses to agonists and induces eotaxin production. We investigated the effects of pre-treatment with IL-4, IL-13 and IFN-γ on the responses of HASM cells to IL-13. Methods Cultured HASM were examined for expression of IL-13 receptor subunits using polymerase chain reaction, immunofluorescence microscopy and flow cytometry. Effects of cytokine pre-treatment on IL-13-induced cell responses were assessed by looking at STAT6 phosphorylation using Western blot, eotaxin secretion and calcium responses to histamine. Results IL-13Rα1, IL-4Rα and IL-13Rα2 subunits were expressed on HASM cells. IL-13 induced phosphorylation of STAT6 which reached a maximum by 30 minutes. Pre-treatment with IL-4, IL-13 and, to a lesser degree, IFN-γ reduced peak STAT6 phosphorylation in response to IL-13. IL-13, but not IFN-γ, pre-treatment abrogated IL-13-induced eotaxin secretion. Pre-treatment with IL-4 or IL-13 abrogated IL-13-induced augmentation of the calcium transient evoked by histamine. Cytokine pre-treatment did not affect expression of IL-13Rα1 and IL-4Rα but increased expression of IL-13Rα2. An anti-IL-13Rα2 neutralizing antibody did not prevent the cytokine pre-treatment effects on STAT6 phosphorylation. Cytokine pre-treatment increased SOCS-1, but not SOCS-3, mRNA expression which was not associated with significant increases in protein expression. Conclusion Pre-treatment with IL-4 and IL-13, but not IFN-γ, induced desensitization of the HASM cells to IL-13 as measured by eotaxin secretion and calcium transients to histamine

IL-33 Enhanced the Proliferation and Constitutive Production of IL-13 and IL-5 by Fibrocytes

Directory of Open Access Journals (Sweden)

Hisako Hayashi

2014-01-01

Full Text Available Interleukin-33 appears to play important roles in the induction of allergic airway inflammation. However, whether IL-33 is involved in airway remodeling remains unclear. Because fibrocytes contribute to tissue remodeling in the setting of chronic inflammation, we examined the effects of IL-33 on fibrocyte functions. Fibrocytes were generated in vitro from peripheral blood mononuclear cells by culturing in the presence of platelet derived growth factors and the cells were stimulated with IL-33. IL-33 enhanced cell proliferation, α-SMA expression, and pro-MMP-9 activity by the fibrocytes without increasing endogenous transforming growth factor-β1 production. Fibrocytes constitutively expressed IL-13 and IL-5, and their production was augmented by stimulation with IL-33. Dexamethasone inhibited the functions of fibrocytes, but IL-33 made fibrocytes slightly refractory to the inhibitory effect of dexamethasone in terms of IL-13 production. Montelukast suppressed IL-13 production by nonstimulated fibrocytes but not those stimulated by IL-33. These findings suggest that IL-33 is involved in the airway remodeling process through its modulation of fibrocyte function independent of antigen stimulation. IL-33 might partially reduce the therapeutic effects of glucocorticoid and cysteinyl leukotriene receptor antagonist on fibrocyte-mediated Th2 responses.

Tumor-associated macrophages (TAMs) are known to promote cancer progression and metastasis through the release of a variety of cytokines. Phosphatase of regenerating liver (PRL-3) has been considered as a marker of colorectal cancer (CRC) liver metastasis. Our previous research suggests that PRL-3 can enhance the metastasis of CRC through the up-regulation of intermediate-conductance Ca 2+ -activated K + (KCNN4) channel, which is dependent on the autocrine secretion of tumor necrosis factor-alpha (TNF-α). However, whether TAMs participate in the progression and metastasis of CRC induced by PRL-3 remains unknown. We used flow cytometry, coculture, western blotting, invasion assays, real-time quantitative PCR, chromatin immunoprecipitation, luciferase reporter assays, and immunofluorescence staining to determine the effect of TAMs on the ability of PRL-3 to promote invasiveness of CRC cells. In this study, we found that TAMs facilitated the metastasis of CRC induced by PRL-3. When TAMs were cocultured with CRC cells, the expression of KCNN4 was increased in TAMs and the invasion of CRC cells was enhanced. Furthermore, cytokines that were secreted by TAMs, such as IL-6 and IL-8, were also significantly increased. This response was attenuated by treating TAMs with the KCNN4 channel-specific inhibitor, 1-[(2-chlorophenyl) diphenylmethyl]-1H-pyrazole (TRAM-34), which suggested that KCNN4 channels may be involved in inducing the secretion of IL-6 and IL-8 by TAMs and improving CRC cell invasiveness. Moreover, the expression of KCNN4 channels in TAMs was regulated through the NF-κB signal pathway, which is activated by TNF-α from CRC cells. Immunofluorescence analysis of colorectal specimens indicated that IL-6 and IL-8 double positive cells in the stroma showed positive staining for the TAM marker CD68, suggesting that TAMs produce IL-6 and IL-8. Increased numbers of these cells correlated with higher clinical stage. Our findings suggested that TAMs participate in the

IL-1 and IL-23 mediate early IL-17A production in pulmonary inflammation leading to late fibrosis.

Directory of Open Access Journals (Sweden)

Paméla Gasse

Full Text Available BACKGROUND: Idiopathic pulmonary fibrosis is a devastating as yet untreatable disease. We demonstrated recently the predominant role of the NLRP3 inflammasome activation and IL-1β expression in the establishment of pulmonary inflammation and fibrosis in mice. METHODS: The contribution of IL-23 or IL-17 in pulmonary inflammation and fibrosis was assessed using the bleomycin model in deficient mice. RESULTS: We show that bleomycin or IL-1β-induced lung injury leads to increased expression of early IL-23p19, and IL-17A or IL-17F expression. Early IL-23p19 and IL-17A, but not IL-17F, and IL-17RA signaling are required for inflammatory response to BLM as shown with gene deficient mice or mice treated with neutralizing antibodies. Using FACS analysis, we show a very early IL-17A and IL-17F expression by RORγt(+ γδ T cells and to a lesser extent by CD4αβ(+ T cells, but not by iNKT cells, 24 hrs after BLM administration. Moreover, IL-23p19 and IL-17A expressions or IL-17RA signaling are necessary to pulmonary TGF-β1 production, collagen deposition and evolution to fibrosis. CONCLUSIONS: Our findings demonstrate the existence of an early IL-1β-IL-23-IL-17A axis leading to pulmonary inflammation and fibrosis and identify innate IL-23 and IL-17A as interesting drug targets for IL-1β driven lung pathology.

Given the increase in childhood food allergy, national and local policies have been developed to encourage schools to stock undesignated epinephrine auto-injectors in case of an anaphylactic emergency. To describe the use of epinephrine auto-injectors in Chicago Public Schools during the 2012-2013 school year, specifically for food-induced allergic reactions. District-issued epinephrine auto-injectors were distributed to all public and charter schools in Chicago prior to the start of the 2012-2013 school year. Data on their use were collected, and frequencies were computed in the autumn of 2013. Thirty-eight district-issued epinephrine auto-injectors were administered during the inaugural year of the Chicago Public Schools initiative. Epinephrine auto-injectors were administered to students (92.1%) and school staff (7.9%). Most district-issued epinephrine auto-injectors were administered in elementary schools (63.2%) and on Chicago's North-Northwest Side (36.8%). More than half (55.0%) of all district-issued epinephrine auto-injectors were administered for first-time anaphylactic events. Food-induced reactions accounted for more than half (55.3%) of all reactions requiring epinephrine auto-injector use, whereas the trigger of more than one third (34.2%) of all reactions requiring the use of an epinephrine auto-injector remained unknown. Chicago Public Schools is the first large, urban school district in the U.S. to develop and implement the District-Issued Emergency Epinephrine Initiative, which helped 38 students and staff avoid potential morbidity and mortality. The impact of this initiative during its first year underscores the need for stocking undesignated epinephrine in schools across the country. Copyright © 2015 American Journal of Preventive Medicine.

Quantitative Contribution of IL2Rγ to the Dynamic Formation of IL2-IL2R Complexes.

Directory of Open Access Journals (Sweden)

Luis F Ponce

Full Text Available Interleukin-2 (IL2 is a growth factor for several immune cells and its function depends on its binding to IL2Rs in the cell membrane. The most accepted model for the assembling of IL2-IL2R complexes in the cell membrane is the Affinity Conversion Model (ACM. This model postulates that IL2R receptor association is sequential and dependent on ligand binding. Most likely free IL2 binds first to IL2Rα, and then this complex binds to IL2Rβ, and finally to IL2Rγ (γc. However, in previous mathematical models representing this process, the binding of γc has not been taken into account. In this work, the quantitative contribution of the number of IL2Rγ chain to the IL2-IL2R apparent binding affinity and signaling is studied. A mathematical model of the affinity conversion process including the γ chain in the dynamic, has been formulated. The model was calibrated by fitting it to experimental data, specifically, Scatchard plots obtained using human cell lines. This paper demonstrates how the model correctly explains available experimental observations. It was estimated, for the first time, the value of the kinetic coefficients of IL2-IL2R complexes interaction in the cell membrane. Moreover, the number of IL2R components in different cell lines was also estimated. It was obtained a variable distribution in the number of IL2R components depending on the cell type and the activation state. Of most significance, the study predicts that not only the number of IL2Rα and IL2Rβ, but also the number of γc determine the capacity of the cell to capture and retain IL2 in signalling complexes. Moreover, it is also showed that different cells might use different pathways to bind IL2 as consequence of its IL2R components distribution in the membrane.

To evaluate the relationship and the clinical significance between the serum IL-8, IL-10, IL-12 and IgE in patients with asthma, the serum IL-8, IL-10 are measured by radioimmunoassay method and the serum IL-12, IgE by ELISA in 55 patients with asthma. The level of serum IL-8, IgE at stage of episode are significantly higher than that at stage of remission (P<0.01); the level of serum IL-10, IL-12 at stage of episode are significantly lower than that at stage of remission (P<0.01). Linear regression shows that the decrease of IL-12 relate to the increase of IgE. The results suggests that the change of the level of serum IL-8, IL-10, IL-12 and IgE could be a maker for the aggravation of asthma

Full Text Available Asthma is a reversible airway obstruction that is characterized by constriction of airway smooth muscle, hyper secretion of mucus, edema and airway hyper responsiveness (AHR, mucus secretion and thickening of the basement membrane underlying the airway epithelium. During the process of airway inflammation, complex interactions of innate and adaptive immune cells as well as structural cells and their cytokines have many important roles. It was believed that airway inflammation is orchestrated by allergen specific T helper (Th 2 cells, which recruit and accumulate in the lungs and produce a range of different effector cytokines. However, more recent studies have revealed the potential collaboration of other helper T cells and their cytokines in this process. Th17 cell may have a role in severe asthma and chronic obstructive pulmonary disease (COPD. Interleukin (IL-9-producing subset called Th9 cell, Th22 cells which primarily secrete IL-22, IL-13 and tumor necrosis factor-α and Th25 cells via producing IL-25 are believed to be important for initiating allergic reactions and developing airway inflammation. Cytokines are important in asthma and play a critical role in orchestrating the allergic inflammatory response, although the precise role of each cytokine remains to be determined. The aim of this review is to summarize the current knowledge about the possible roles of newly identified helper T cells derived cytokines (IL-9, 17, 22, 25 and IL-33 in asthma. The potential therapeutic applications emerging from the roles of these cytokines will be discussed as well.

The dichotomous pattern of IL-12r and IL-23R expression elucidates the role of IL-12 and IL-23 in inflammation.

Full Text Available IL-12 and IL-23 cytokines respectively drive Th1 and Th17 type responses. Yet, little is known regarding the biology of these receptors. As the IL-12 and IL-23 receptors share a common subunit, it has been assumed that these receptors are co-expressed. Surprisingly, we find that the expression of each of these receptors is restricted to specific cell types, in both mouse and human. Indeed, although IL-12Rβ2 is expressed by NK cells and a subset of γδ T cells, the expression of IL-23R is restricted to specific T cell subsets, a small number of B cells and innate lymphoid cells. By exploiting an IL-12- and IL-23-dependent mouse model of innate inflammation, we demonstrate an intricate interplay between IL-12Rβ2 NK cells and IL-23R innate lymphoid cells with respectively dominant roles in the regulation of systemic versus local inflammatory responses. Together, these findings support an unforeseen lineage-specific dichotomy in the in vivo role of both the IL-12 and IL-23 pathways in pathological inflammatory states, which may allow more accurate dissection of the roles of these receptors in chronic inflammatory diseases in humans.

Role of periostin, FENO, IL-13, lebrikzumab, other IL-13 antagonist and dual IL-4/IL-13 antagonist in asthma.

Asthma markedly diminishes quality of life due to limited activity, absences from work or school and hospitalizations. Patients with severe asthma which are not controlled despite taking effective therapy are most in need of new treatment approaches. IL-13 was demonstrated as 'central mediator of allergic asthma'. IL-13 has been implicated in the pathogenesis of asthma, idiopathic pulmonary fibrosis and COPD. IL-13 levels in the sputum and bronchial biopsy samples remain elevated in severe asthma despite the use of inhaled and systemic corticosteroids. Thus, IL-13 is a mediator involved in corticosteroid resistance. Periostin enhances profibrotic TGF-β signaling in subepithelial fibrosis associated with asthma. IL-13 induces bronchial epithelial cells to secrete periostin. Periostin may be a biomarker for Th2 induced airway inflammation. Lebrikizumab is a monoclonal antibody against IL-13. Lebrikizumab improved lung function in asthmatics who were symptomatic despite treatment with long acting beta agonist and inhaled corticosteroids and provided benefit in the treatment of severe uncontrolled asthma. Lebrikizumab block IL-13 signaling through the IL-13Rα1/IL-4Rα receptor. There was a larger reduction in FENO in the high periostin subgroup than in the low periostin subgroup (34.4 vs 4.3%). Serum CCL17, CCL13 and total IgE levels decreased in the lebrikizumab group.

Atherosclerosis is a chronic inflammatory disease. Lesion progression is primarily mediated by cells of the monocyte/macrophage lineage. IL-17A is a proinflammatory cytokine, which modulates immune cell trafficking and is involved inflammation in (auto)immune and infectious diseases. But the role of IL-17A still remains controversial. In the current study, we investigated effects of IL-17A on advanced murine and human atherosclerosis, the common disease phenotype in clinical care. The 26-wk-old apolipoprotein E-deficient mice were fed a standard chow diet and treated either with IL-17A mAb (n = 15) or irrelevant Ig (n = 10) for 16 wk. Furthermore, essential mechanisms of IL-17A in atherogenesis were studied in vitro. Inhibition of IL-17A markedly prevented atherosclerotic lesion progression (p = 0.001) by reducing inflammatory burden and cellular infiltration (p = 0.01) and improved lesion stability (p = 0.01). In vitro experiments showed that IL-17A plays a role in chemoattractance, monocyte adhesion, and sensitization of APCs toward pathogen-derived TLR4 ligands. Also, IL-17A induced a unique transcriptome pattern in monocyte-derived macrophages distinct from known macrophage types. Stimulation of human carotid plaque tissue ex vivo with IL-17A induced a proinflammatory milieu and upregulation of molecules expressed by the IL-17A-induced macrophage subtype. In this study, we show that functional blockade of IL-17A prevents atherosclerotic lesion progression and induces plaque stabilization in advanced lesions in apolipoprotein E-deficient mice. The underlying mechanisms involve reduced inflammation and distinct effects of IL-17A on monocyte/macrophage lineage. In addition, translational experiments underline the relevance for the human system. Copyright © 2014 by The American Association of Immunologists, Inc.

IL-5 and IL-5 receptor in asthma

ATC Kotsimbos

1997-12-01

Full Text Available Eosinophils, along with mast cells are key cells involved in the innate immune response against parasitic infection whereas the adaptive immune response is largely dependent on lymphocytes. In chronic parasitic disease and in chronic allergic disease, IL-5 is predominantly a T cell derived cytokine which is particularly important for the terminal differentiation, activation and survival of committed eosinophil precursors. The human IL-5 gene is located on chromosome 5 in a gene cluster that contains the evolutionary related IL-4 family of cytokine genes. The human IL-5 receptor complex is a heterodimer consisting of a unique a subunit (predominantly expressed on eosinophils and a beta subunit which is shared between the receptors for IL-3 & GM-CSF (more widely expressed. The a subunit is required for ligand-specific binding whereas association with the beta subunit results in increased binding affinity. The alternative splicing of the alphaIL-5R gene which contains 14 exons can yield several alphaIL-5R isoforms including a membrane-anchored isoform (alphaIL-5Rm and a soluble isoform (alphaIL-5Rs. Cytokines such as IL-5 produce specific and non-specific cellular responses through specific cell membrane receptor mediated activation of intracellular signal transduction pathways which, to a large part, regulate gene expression. The major intracellular signal transduction mechanism is activation of non-receptor associated tyrosine kinases including JAK and MAP kinases which can then transduce signals via a novel family of transcriptional factors named signal transducers and activators of transcription (STATS. JAK2, STAT1 and STAT 5 appear to be particularly important in IL-5 mediated eosinophil responses. Asthma is characterized by episodic airways obstruction, increased bronchial responsiveness, and airway inflammation. Several studies have shown an association between the number of activated T cells and eosinophils in the airways and abnormalities

Psoriasis is a chronic skin disease resulting from the dysregulated interplay between keratinocytes and infiltrating immune cells. We report on a psoriasis-like disease model, which is induced by the transfer of CD4(+)CD45RB(hi)CD25(-) cells to pathogen-free scid/scid mice. Psoriasis-like lesions had elevated levels of antimicrobial peptide and proinflammatory cytokine mRNA. Also, similar to psoriasis, disease progression in this model was dependent on the p40 common to IL-12 and IL-23. To investigate the role of IL-22, a Th17 cytokine, in disease progression, mice were treated with IL-22-neutralizing antibodies. Neutralization of IL-22 prevented the development of disease, reducing acanthosis (thickening of the skin), inflammatory infiltrates, and expression of Th17 cytokines. Direct administration of IL-22 into the skin of normal mice induced both antimicrobial peptide and proinflammatory cytokine gene expression. Our data suggest that IL-22, which acts on keratinocytes and other nonhematopoietic cells, is required for development of the autoreactive Th17 cell-dependent disease in this model of skin inflammation. We propose that IL-22 antagonism might be a promising therapy for the treatment of human psoriasis.

Full Text Available Background. We aimed in our study to research the role of new cytokines such as IL-35, IL-22, and IL-17 that may form a target for novel treatment approaches. Methods. IL-10, IL-17, TGF-β, IFN-γ, IL-22, and IL-35 serum levels of allergic rhinitis (AR patients were measured using ELISA method. Allergic sensitization was demonstrated by the skin prick test. Patients only with olive tree sensitivity were evaluated for seasonal AR (SAR. Patients only with mite sensitivity were included in the study for perennial AR (PAR. AR clinic severity was demonstrated by the nasal symptom scores (NSS. Results. In total, 65 AR patients (patient group, having 31 PAR and 34 SAR patients, and 31 healthy individuals (control group participated in the study. Cytokine levels between the patient group and the control group were compared; IL-17 (p=0.038, IL-22 (p=0.001, and TGF-β (p=0.031 were detected as high in the patient group, and IFN-γ (p<0.001 was detected as low in the patient group. When correlation analysis was made between age, gender, prick test result, NSS, AR duration, and cytokine levels in the patient group, a negative correlation was detected only between IFN-γ (p=0.032/r=−0.266 level and NSS. Conclusions. Accompanied by the literature information, these results made us think that T cell subgroups and cytokines have an important role in AR immunopathogenesis. It is thought that future studies to be conducted relating to this subject will form new targets in treatment.

Getting to the CORE of the Chicago Teachers’ Union Transformation

Directory of Open Access Journals (Sweden)

Peter Brogan

2014-05-01

Full Text Available This article draws on a comparative study of urban change and rank-and-file teacher rebellion in New York City and Chicago, to explore the contemporary dynamics of what Jamie Peck (2013 calls “austerity urbanism” and its relationship to a rebirth of a social justice, grassroots teacher unionism in US urban centres. Tracing the trajectories of one group of rank-and-file teacher dissidents in Chicago, it argues that municipal unions are uniquely situated to lead the fight against austerity urbanism and the crisis tendencies of contemporary capitalism. To do this, however, trade unions will need to be reinvented and a different form of working class politic forged, grounded both in and outside of the trade union movement. Only then may we see organized labour in North America contribute to a movement for radical and systemic change, which is key to building a more socially just urbanism and society more broadly. The case of the Chicago teachers is highly instructive for activists, both inside and outside of the North American labour movement.

The development of nephritis is a leading cause of morbidity and mortality in lupus patients. Although the general pathophysiological progression of lupus nephritis is known, the molecular mediators and mechanisms are incompletely understood. Previously, we demonstrated that the glycosphingolipid (GSL) catabolic pathway is elevated in the kidneys of MRL/lpr lupus mice and human lupus patients with nephritis. Specifically, the activity of neuraminidase (NEU) and expression of Neu1, an enzyme in the GSL catabolic pathway is significantly increased. To better understand the role and mechanisms by which this pathway contributes to the progression of LN, we analyzed the expression and effects of NEU activity on the function of MRL/lpr lupus-prone mesangial cells (MCs). We demonstrate that NEU1 and NEU3 promote IL-6 production in MES13 MCs. Neu1 expression, NEU activity, and IL-6 production are significantly increased in stimulated primary MRL/lpr lupus-prone MCs, and blocking NEU activity inhibits IL-6 production. NEU1 and NEU3 expression overlaps IgG deposits in MCs in vitro and in renal sections from nephritic MRL/lpr mice. Together, our results suggest that NEU activity mediates IL-6 production in lupus-prone MCs possibly through an IgG-receptor complex signaling pathway.

Vitiligo inducing phenols activate the unfolded protein response in melanocytes resulting in upregulation of IL6 and IL8

Vitiligo is characterized by depigmented skin patches due to loss of epidermal melanocytes. Oxidative stress may play a role in vitiligo onset, while autoimmunity contributes to disease progression. In this study we sought to identify mechanisms that link disease triggers and spreading of lesions. A hallmark of melanocytes at the periphery of vitiligo lesions is dilation of the endoplasmic reticulum (ER). We hypothesized that oxidative stress results in redox disruptions that extend to the ER, causing accumulation of misfolded peptides, which activates the unfolded protein response (UPR). We used 4-tertiary butyl phenol (4-TBP) and monobenzyl ether of hydroquinone (MBEH), known triggers of vitiligo. We show that expression of key UPR components, including the transcription factor X-box binding protein 1 (XBP1), are increased following exposure of melanocytes to phenols. XBP1 activation increases production of immune mediators interleukin-6 (IL6) and IL8. Co-treatment with XBP1 inhibitors reduced IL6 and IL8 production induced by phenols, while over-expression of XBP1 alone increased their expression. Thus, melanocytes themselves produce cytokines associated with activation of an immune response following exposure to chemical triggers of vitiligo. These results expand our understanding of the mechanisms underlying melanocyte loss in vitiligo and pathways linking environmental stressors and autoimmunity. PMID:22696056

Interleukin-10 (IL-10) plays an important role in the immunity to hepatitis C virus (HCV). Insofar as IL-10 variants are associated with altered levels of IL-10, previous studies that examined the association of IL-10 polymorphisms with the susceptibility to and progression of chronic HCV, and response to anti-viral treatment were inconsistent. We investigated the association between common IL-10 variants in the intron and the promotor region with HCV and associated features. Study subjects comprised 120 patients infected with HCV-1b, and treated with Peg-IFN/RBV. Genotyping of six IL-10 promoter variants in the intron region (rs1878672, rs1554286, rs1518111) and promotor region (rs1800872, rs1800871, rs1800896) were done by real-time PCR. Compared to G/G, carriage of IL-10 rs1800896 (-1082A/G) A/A genotype was more frequent in patients with sustained virological response (SVR). The decline in viral load over the first 12weeks of treatment was more pronounced in rs1800896 A/A genotype carriers, compared to G/G genotype carriers, and was irrespective of the treatment dosage. Carriage of rs1800896 A/A genotype was positively associated with improvement in viral load decline, which was simultaneous, with and without carriage of the common favourable IL-28B variant. Carriage of both IL-10 rs1800896 G/G and IL-28B non-favourable genotype was associated with twice the risk of getting slow decline of viral load during treatment. Haploview analysis identified ACGCTA and CCGCTG haplotypes to be linked with excellent PegIFN/RBV cure rate, and complete HCV eradication. On the other hand, ACGCTG and CCGCTA haplotypes were associated with resistance to PegIFN/RBV treatment. IL-10 rs1800896 variant markedly influences the clinical outcome of HCV infection, and is a determinant of the response to HCV treatment. Copyright © 2017 Elsevier Ltd. All rights reserved.

Endogenous IL-22 Plays a Dual Role in Arthritis: Regulation of Established Arthritis via IFN-γ Responses

Justa, Shivali; Zhou, Xiaoqun; Sarkar, Sujata

2014-01-01

Objective IL-22 is elevated in patients with inflammatory arthritis and correlates with disease activity. IL-22 deficient mice have reduced incidence of arthritis. Recombinant IL-22 restrains progression of arthritis via increase in IL-10 responses when administered prior to onset of arthritis. These findings imply a possible dual role of IL-22 in inflammatory arthritis depending on the phase of arthritis. Experiments outlined here were designed to elucidate the contribution of endogenous IL-22 before and after the onset of arthritis. Methods Collagen induced arthritis (CIA) was induced in DBA1 or IFN-γ deficient mice following immunization with collagen and complete Freund's adjuvant. Anti-IL-22 antibody or isotype control were administered prior to or after onset of arthritis and disease progression assessed by clinical scoring and histopathology. IL-22, IL-17 and IFN-γ responses were measured by ELISA and flowcytometry. Anti-collagen antibody responses were analyzed by ELISA. Expression of IL-22R1 in CD4+ cells was elucidated by flowcytometry and real time PCR. Results Collagen specific IL-22 responses were expanded during arthritis and IL-22 producing cells were discrete from IL-17 or IFN-γ producing cells. Neutralization of IL-22 after onset of arthritis resulted in significant increase in Th1 responses and significantly reduced severity of arthritis. CD4+ cells from arthritic mice showed increased surface expression of IL-22R1. In vitro, CD4+T cells cultured with antigen presenting cells in the presence or absence of IL-22 suppressed or induced IFN-γ, respectively. The protective effect of anti-IL-22 was reversed in IFN-γ deficient mice. Moreover, administration of anti-IL-22 prior to onset of arthritis augmented arthritis severity. Conclusion We show for the first time that IL-22 plays a dual role: protective prior to the onset of arthritis and pathogenic after onset of arthritis. The pathogenic effect of IL-22 is dependent on suppression of IFN

To compare the use of complementary and alternative medicine (CAM) for arthritis between 2 ethnically distinct metropolitan Chicago community areas. A telephone interview survey of adults age 45 years or above living in North (88.9% white) or South (79.7% African American) areas. Of 763 respondents, 405 reported arthritis or chronic joint symptoms and were asked about use and satisfaction with 7 CAM therapies. Differences between areas were compared with population-weighted tests; multiple logistic regression was used to analyze the likelihood of CAM use controlled for demographics, behavioral risk factors, and arthritis severity. South Chicago respondents had a higher prevalence and more severe arthritis symptoms such as mean joint pain and more functional limitations. Use of CAM therapy by South Chicago respondents, most commonly massage and relaxation techniques, was 10% greater than North Chicago respondents (61.5% to 51%) but this was not significantly different. Among CAM users, South Chicago respondents reported higher satisfaction with 6 of the 7 CAM therapies and greater future interest in CAM therapies. Poor overall health status (P=0.03), arthritis pain (P=0.005), and concomitant use of prescription medications (P=0.03) were the only significant predictors of CAM use. Although there were only small differences in overall CAM use by area, older residents of largely African American communities were enthusiastic users of relaxation, massage, and nutritional and dietary techniques. CAM modalities could be important adjuncts to traditional medical treatment of arthritis pain for minority communities.

Full Text Available Si bien muchos manuales sitúan parte de los orígenes de la historia de la sociología en la Escuela de Chicago con Mead, Dewey, Thomas, etc., pocos son los que recogen los nombres, los retratos y los trabajos de las mujeres que desde la Universidad de Chicago aunaron teoría, investigación y activismo, contribuyendo al afianzamiento de las ciencias sociales dentro y fuera de la academia. Este artículo analiza la obra colectiva de las mujeres de la Escuela de Chicago desde posiciones interdisciplinares y desde la confusión cienciareforma en el contexto de EE.UU. de principios del siglo XX. Para ello recoge a modo de muestra sus trabajos publicados en la American Journal of Sociology desde su número inaugural hasta 1920. Con ello se pretende reflexionar sobre las políticas de género y reconocimiento dentro de las ciencias sociales y sobre la supuesta neutralidad de su historia.

IL-25 inhibits atherosclerosis development in apolipoprotein E deficient mice.

Directory of Open Access Journals (Sweden)

Polyxeni T Mantani

Full Text Available IL-25 has been implicated in the initiation of type 2 immunity and in the protection against autoimmune inflammatory diseases. Recent studies have identified the novel innate lymphoid type 2 cells (ILC2s as an IL-25 target cell population. The purpose of this study was to evaluate if IL-25 has any influence on atherosclerosis development in mice.Administration of 1 μg IL-25 per day for one week to atherosclerosis-prone apolipoprotein (apoE deficient mice, had limited effect on the frequency of T cell populations, but resulted in a large expansion of ILC2s in the spleen. The expansion was accompanied by increased levels of anti-phosphorylcholine (PC natural IgM antibodies in plasma and elevated levels of IL-5 in plasma and spleen. Transfer of ILC2s to apoE deficient mice elevated the natural antibody-producing B1a cell population in the spleen. Treatment of apoE/Rag-1 deficient mice with IL-25 was also associated with extensive expansion of splenic ILC2s and increased plasma IL-5, suggesting ILC2s to be the source of IL-5. Administration of IL-25 in IL-5 deficient mice resulted in an expanded ILC2 population, but did not stimulate generation of anti-PC IgM, indicating that IL-5 is not required for ILC2 expansion but for the downstream production of natural antibodies. Additionally, administration of 1 μg IL-25 per day for 4 weeks in apoE deficient mice reduced atherosclerosis in the aorta both during initiation and progression of the disease.The present findings demonstrate that IL-25 has a protective role in atherosclerosis mediated by innate responses, including ILC2 expansion, increased IL-5 secretion, B1a expansion and natural anti-PC IgM generation, rather than adaptive Th2 responses.

Background Interleukin-17 (IL-17), a cytokine mainly secreted by Th17 cells, seems to play a significant role in the pathogenesis of rheumatoid arthritis (RA). Functional genetic polymorphisms in IL-17 and its receptor genes can influence either qualitatively or quantitatively their functions. Therefore, we aimed to study the impact of IL17-A and IL17RC polymorphisms on plasma level of IL-17 and RA susceptibility and severity. Methods In this context, IL-17A*rs2275913 and IL-17RC*rs708567 polymorphisms were investigated together with the quantification of IL17 plasma level in 115 RA patients and 91 healthy control subjects matched in age, sex and ethnic origin. Results There were no statistically significant associations between IL-17A and IL-17RC studied polymorphisms and RA susceptibility. In contrast, IL-17A plasma levels were significantly higher in patients (55.07 pg/ml) comparatively to controls (4.75 pg/ml), p<10E-12. A ROC curve was used to evaluate the performance of plasma IL-17 in detecting RA. Given 100% specificity, the highest sensitivity of plasma IL-17A was 61.7% at a cut-off value of 18.25 pg/ml; p < 10E-21, CI = [0.849–0.939]. Analytic results showed that the IgM-rheumatoid factor and anti-CCP antibodies were significantly less frequent in patients with the IL-17RC*A/A genotype than those carrying *G/G and *G/A genotypes; p = 0.013 and p = 0.015, respectively. Otherwise, IL-17 plasma levels’ analysis showed a significant association with the activity of RA (DAS28≥5.1 = 74.71 pg/ml vs. DAS28<5.1 = 11.96 pg/ml), p<10E-6. Conclusion IL-17A*rs2275913 (G/A) and IL-17RC*rs708567 (G/A) polymorphisms did not seem to influence RA susceptibility in Tunisian population. This result agrees with those reported previously. Plasma IL-17A level seems to be predictive of severe RA occurrence. PMID:29584788

We aimed to investigate the associations between polymorphisms of interleukin-1A (IL-1A), IL-1B, and IL-1 receptor antagonist (IL-1RN) and prostate cancer (PCa) risk. A comprehensive search for articles of MEDLINE and EMBASE databases and bibliographies of retrieved articles published up to August 3, 2014 was performed. Methodological quality assessment of the trials was based on a standard quality scoring system. The meta-analysis was performed using STATA 12.0. We included 9 studies (1 study for IL-1A, 5 studies for IL-1B, and 3 studies for IL-1RN), and significant association was found between polymorphisms of IL-1B-511 (rs16944) as well as IL-1B-31 (rs1143627) and PCa risk. IL-1B-511 (rs16944) polymorphism was significantly associated with PCa risk in homozygote and recessive models, as well as allele contrast (TT vs CC: OR, 0.74; 95%CI, 0.58-0.94; P=0.012; TT vs TC+CC; OR, 0.79; 95%CI, 0.63-0.98; P=0.033; T vs C: OR, 0.86; 95%CI, 0.77-0.96; P=0.008). The association between IL-1B-31 (rs1143627) polymorphism and PCa risk was weakly significant under a heterozygote model (OR, 1.35; 95%CI, 1.00-1.80; P=0.047). Sequence variants in IL-1B-511 (rs16944) and IL-1B-31 (rs1143627) are significantly associated with PCa risk, which provides additional novel evidence that proinflammatory cytokines and inflammation play an important role in the etiology of PCa.

Glucocorticoids inhibit the proliferation of IL-2-dependent T cell clones

International Nuclear Information System (INIS)

Fresno, M.; Redondo, J.M.; Lopez-Rivas, A.

1986-01-01

It has been shown that glucocorticoids inhibit mitogen or antigen-induced lymphocyte proliferation by decreasing the production of interleukin-2 (IL-2). They have studied the effect of dexamethasone (Dx) on the proliferation of IL-2-dependent T cell clones. They have found that preincubation of these clones with Dx inhibits ( 3 H) thymidine incorporation and cell proliferation in a dose-dependent manner (ID 50 % 5 x 10 -10 M). The inhibition of DNA synthesis by Dx was dependent on the concentration of IL-2. High concentration of IL-2 reversed completely this inhibition. The action of Dx seems to be mediated through the induction of a protein since the simultaneous presence of cycloheximide and Dx prevented the inhibitory effect of the latter. Moreover, dialyzed conditioned medium of Dx treated cells inhibited DNA synthesis by T cell clones. The biochemical characterization of this protein is in progress

Psoriasis is a chronic skin disease resulting from the dysregulated interplay between keratinocytes and infiltrating immune cells. We report on a psoriasis-like disease model, which is induced by the transfer of CD4+CD45RBhiCD25– cells to pathogen-free scid/scid mice. Psoriasis-like lesions had elevated levels of antimicrobial peptide and proinflammatory cytokine mRNA. Also, similar to psoriasis, disease progression in this model was dependent on the p40 common to IL-12 and IL-23. To investigate the role of IL-22, a Th17 cytokine, in disease progression, mice were treated with IL-22–neutralizing antibodies. Neutralization of IL-22 prevented the development of disease, reducing acanthosis (thickening of the skin), inflammatory infiltrates, and expression of Th17 cytokines. Direct administration of IL-22 into the skin of normal mice induced both antimicrobial peptide and proinflammatory cytokine gene expression. Our data suggest that IL-22, which acts on keratinocytes and other nonhematopoietic cells, is required for development of the autoreactive Th17 cell–dependent disease in this model of skin inflammation. We propose that IL-22 antagonism might be a promising therapy for the treatment of human psoriasis. PMID:18202747

To characterize noise exposure of riders on Chicago Transit Authority (CTA) trains, we measured noise levels twice on each segment of 7 of the 8 CTA train lines, which are named after colors, yielding 48 time-series measurements. We found the Blue Line has the highest noise levels compared to other train lines, with mean 76.9 dBA; and that the maximum noise level, 88.9 dBA occurred in the tunnel between the Chicago and Grand stations. Train segments involving travel through a tunnel had significantly higher noise levels than segments with travel on elevated and ground level tracks. While 8-hr doses inside the passenger cars were not estimated to exceed occupational exposure limits, train operators ride in a separate cab with operational windows and may therefore have higher noise exposures than riders. Despite the low risk of hearing loss for riders on CTA trains, in part because transit noise accounts for a small part of total daily noise exposure, 1-min average noise levels exceeded 85 dBA at times. This confirms anecdotal observations of discomfort due to noise levels, and indicates a need for noise management, particularly in tunnels.

Garcia, C.M.; Oberg, K.; Garcia, M.H.

2007-01-01

A unique set of observations of stratified flow phenomena in the Chicago River was made using an upward-looking acoustic Doppler current profiler (ADCP) during the period November 20, 2003 to February 1, 2004. Water density differences between the Chicago River and its North Branch (NB) seem to be responsible for the development of gravity currents. With the objective of characterizing the occurrence, frequency, and evolution of such currents, the ADCP was configured to continuously collect high-resolution water velocity and echo intensity profiles in the Chicago River at Columbus Drive. During the observation period, 28 gravity current events were identified, lasting a total of 77% of the time. Sixteen of these events were generated by underflows from the NB and 12 of these events were generated by overflows from the NB. On average, the duration of the underflow and overflow events was 52.3 and 42.1 h, respectively. A detailed analysis of one underflow event, which started on January 7, 2004, and lasted about 65h, was performed. This is the first time that ADCP technology has been used to continuously monitor gravity currents in a river. ?? 2007 ASCE.

Interleukin (IL)-1β, which is elevated in oral diseases including gingivitis, stimulates epithelial cells to produce IL-8 and perpetuate inflammatory responses. This study investigates stimulatory effects of salivary IL-1β in IL-8 production and determines if aloin inhibits IL-1β-stimulated IL-8 production in epithelial cells. Saliva was collected from volunteers to determine IL-1β and IL-8 levels. Samples from volunteers were divided into two groups: those with low and those with high IL-1β levels. KB cells were stimulated with IL-1β or saliva with or without IL-1 receptor agonist or specific mitogen-activated protein kinase (MAPK) inhibitors. IL-8 production was measured by enzyme-linked immunosorbent assay (ELISA). MAPK protein expression involved in IL-1β-induced IL-8 secretion was detected by Western blot. KB cells were pretreated with aloin, and its effect on IL-1β-induced IL-8 production was examined by ELISA and Western blot analysis. Saliva with high IL-1β strongly stimulated IL-8 production in KB cells, and IL-1 receptor agonist significantly inhibited IL-8 production. Low IL-1β-containing saliva did not increase IL-8 production. IL-1β treatment of KB cells induced activation of MAPK signaling molecules as well as nuclear factor-kappa B. IL-1β-induced IL-8 production was decreased by p38 and extracellular signal-regulated kinase (ERK) inhibitor treatment. Aloin pretreatment inhibited IL-1β-induced IL-8 production in a dose-dependent manner and inhibited activation of the p38 and ERK signaling pathway. Finally, aloin pretreatment also inhibited saliva-induced IL-8 production. Results indicated that IL-1β in saliva stimulates epithelial cells to produce IL-8 and that aloin effectively inhibits salivary IL-1β-induced IL-8 production by mitigating the p38 and ERK pathway. Therefore, aloin may be a good candidate for modulating oral inflammatory diseases.

IL-1 family members IL-18 and IL-33 upregulate the inflammatory potential of differentiated human Th1 and Th2 cultures

Blom, Lars; Poulsen, Lars K.

2012-01-01

The IL-1 family members IL-1ß, IL-18, and IL-33 are potent cytokines in relationship to amplifying the CD4(+) T cell cytokine production. To evaluate their impact on in vitro-differentiated human Th1 and Th2 cultures, such cultures were established from naive T cells, purified from healthy blood...... donors, and reactivated in the presence of IL-1ß, IL-18, or IL-33. Interestingly, we observe modifying responses in Th1 and Th2 cultures induced by IL-18 or IL-33 but not by IL-1ß, both contributing to amplify production of IL-5, IL-13, and IFN-¿. IL-18 or IL-33 stimulation of Th1 cultures resulted...... in increased IFN-¿ and IL-13 production concurrent with reduced IL-10 gene transcription and secretion even though Th1 cultures, in contrast to IL-18Ra, had low ST2L expression. Furthermore, adding IL-18 to Th1 cultures promoted Tbet mRNA expression and production. Th2 cultures stimulated with IL-18 or IL-33...

Correlative human studies suggest that the pleiotropic cytokine interleukin-6 (IL6) contributes to the development and/or progression of prostate cancer. However, the source of IL6 production in the prostate microenvironment in patients has yet to be determined. The cellular origin of IL6 in primary and metastatic prostate cancer was examined in formalin-fixed, paraffin-embedded (FFPE) tissues using a highly sensitive and specific chromogenic in situ hybridization (CISH) assay that underwent extensive analytical validation. Quantitative RT-PCR (q-RT-PCR) showed that benign prostate tissues often had higher expression of IL6 mRNA than matched tumor specimens. CISH analysis further indicated that both primary and metastatic prostate adenocarcinoma cells do not express IL6 mRNA. IL6 expression was highly heterogeneous across specimens and was nearly exclusively restricted to the prostate stromal compartment – including endothelial cells and macrophages among other cell types. The number of IL6-expressing cells correlated positively with the presence of acute inflammation. In metastatic disease, tumor cells were negative in all lesions examined and IL6 expression was restricted to endothelial cells within the vasculature of bone metastases. Finally, IL6 was not detected in any cells in soft tissue metastases. These data suggest that, in prostate cancer patients, paracrine rather than autocrine IL6 production is likely associated with any role for the cytokine in disease progression. PMID:26048576

The mechanisms responsible for the evolution of steatosis towards NASH (non-alcoholic steatohepatitis) and fibrosis are not completely defined. In the present study we evaluated the role of CD4(+) T-helper (Th) cells in this process. We analysed the infiltration of different subsets of CD4(+) Th cells in C57BL/6 mice fed on a MCD (methionine choline-deficient) diet, which is a model reproducing all phases of human NASH progression. There was an increase in Th17 cells at the beginning of NASH development and at the NASH-fibrosis transition, whereas levels of Th22 cells peaked between the first and the second expansion of Th17 cells. An increase in the production of IL (interleukin)-6, TNFα (tumour necrosis factor α), TGFβ (transforming growth factor β) and CCL20 (CC chemokine ligand 20) accompanied the changes in Th17/Th22 cells. Livers of IL-17(-/-) mice were protected from NASH development and characterized by an extensive infiltration of Th22 cells. In vitro, IL-17 exacerbated the JNK (c-Jun N-terminal kinase)-dependent mouse hepatocyte lipotoxicity induced by palmitate. IL-22 prevented lipotoxicity through PI3K (phosphoinositide 3-kinase)-mediated inhibition of JNK, but did not play a protective role in the presence of IL-17, which up-regulated the PI3K/Akt inhibitor PTEN (phosphatase and tensin homologue deleted on chromosome 10). Consistently, livers of IL-17(-/-) mice fed on the MCD diet displayed decreased activation of JNK, reduced expression of PTEN and increased phosphorylation of Akt compared with livers of wild-type mice. Hepatic infiltration of Th17 cells is critical for NASH initiation and development of fibrosis in mice, and reflects an infiltration of Th22 cells. Th22 cells are protective in NASH, but only in the absence of IL-17. These data strongly support the potentiality of clinical applications of IL-17 inhibitors that can prevent NASH by both abolishing the lipotoxic action of IL-17 and allowing IL-22-mediated protection. © 2016 Authors

Interleukin-20 (IL-20) is an IL-10-family cytokine that regulates innate and adaptive immunity in skin and other tissues. In addition to protecting the host from various external pathogens, dysregulated IL-20 signaling has been shown to contribute to the pathogenesis of human psoriasis. IL-20 signals through two cell-surface receptor heterodimers, IL-20R1-IL-20R2 and IL-22R1-IL-20R2. In this report, crystals of the IL-20-IL-20R1-IL-20R2 ternary complex have been grown from polyethylene glycol solutions. The crystals belonged to space group P4{sub 1}2{sub 1}2 or P4{sub 3}2{sub 1}2, with unit-cell parameters a = 111, c = 135 {angstrom}, and diffracted X-rays to 3 {angstrom} resolution. The crystallographic asymmetric unit contains one IL-20-IL-20R1-IL-20R2 complex, corresponding to a solvent content of approximately 54%.

Full Text Available Proinflammatory cytokine IL-18 has been shown to be elevated in the sera of ovarian carcinoma patients. The aim of the study was to examine the levels and cellular origin of IL-18, IL-18 binding protein, and IL-18 receptor in normal and cancerous ovarian tissues. Ovarian tissue samples were examined by immunohistochemical staining for IL-18, IL-18BP, and IL-18R and mRNA of these cytokines was analyzed with semiquantitative PT-PCR. IL-18 levels were significantly higher in cancerous ovarian tissues (P=0.0007, IL-18BP levels were significantly higher in normal ovarian tissues (P=0.04, and the ratio of IL-18/IL-18BP was significantly higher in cancerous ovarian tissues (P=0.036. Cancerous ovarian tissues expressed significantly higher IL-18 mRNA levels (P=0.025, while there was no difference in the expression of IL-18BP mRNA and IL-18R mRNA between cancerous and normal ovarian tissues. IL-18 and IL-18BP were expressed dominantly in the epithelial cells of both cancerous and normal ovarian tissues, while IL-18R was expressed dominantly in the epithelial cells of cancerous ovarian tissues but expressed similarly in the epithelial and stromal cells of normal cancerous tissues. This study indicates a possible role of IL-18, IL-18BP, and IL-18R in the pathogenesis of epithelial ovarian carcinoma.

Influenza virus causes a respiratory disease in humans that can progress to lung injury with fatal outcome. The interleukin (IL)-36 cytokines are newly described IL-1 family cytokines that promote inflammatory responses via binding to the IL-36 receptor (IL-36R). The mechanism of expression and the role of IL-36 cytokines are poorly understood. Here, we investigated the role of IL-36 cytokines in modulating the innate inflammatory response during influenza virus-induced pneumonia in mice. The intranasal administration of influenza virus upregulated IL-36α mRNA and protein production in the lungs. In vitro, influenza virus-mediated IL-36α but not IL-36γ is induced and secreted from alveolar epithelial cells (AECs) through both a caspase-1 and caspase-3/7 dependent pathway. IL-36α was detected in microparticles shed from AECs and promoted the production of pro-inflammatory cytokines and chemokines in respiratory cells. IL-36R-deficient mice were protected from influenza virus-induced lung injury and mortality. Decreased mortality was associated with significantly reduced early accumulation of neutrophils and monocytes/macrophages, activation of lymphocytes, production of pro-inflammatory cytokines and chemokines, and permeability of the alveolar-epithelial barrier in despite impaired viral clearance. Taken together, these data indicate that IL-36 ligands exacerbate lung injury during influenza virus infection.

History of transportation in Chicago: Its impact on the urban landscape

Energy Technology Data Exchange (ETDEWEB)

Plummer, A.V.

1994-12-31

In this paper the author presents some of his thoughts on the relationship between transportation and how Chicago used its land. He has chosen to do this by looking at the question from a historical perspective. He attempts to do this by tracking the link between transportation and the use of land. This linkage actually involves only a few simple human factors such as a desire to pay the least amount for land, getting from place to place as swiftly as possible, being paid the most for work done and living in a country-like setting with all of the serenity that image conjures. The author argues these factors are what brought Chicago to where it is, and makes no attempt to judge this as good or bad. The author argues that energy consumption or scarcity, like railroad or transit strikes, have had little long-term effect on how people travel and therefore how they use land. The notion that resources were inexhaustible permeated Chicago`s early history. Human factors appear to the author to have had and probably will continue to have a more profound effect on transportation than anything else. He does not believe society knows what individuals will pay in energy costs to maintain their real or perceived mobility. The real cost of fuel and vehicles is much higher (and so is transit usage) in Europe, but VMT and vehicle ownership still are growing at an astounding rate. Mobility is perceived as good, not bad. How does one convince people to limit their mobility when it is good?

We recently reported that IL-17A plays a critical role in the development of porcine pancreatic elastase (PPE)-induced emphysema. The proliferation of T-helper type 17 (Th17) cells was induced by IL-23. To determine the contribution of IL-23 to the development of pulmonary emphysema, a mouse model of PPE-induced emphysema was used in which responses of IL-23p19-deficient (IL-23 -/- ) and wild-type (WT) mice were compared. Intratracheal instillation of PPE induced emphysematous changes in the lungs and was associated with increased levels of IL-23 in lung homogenates. Compared with WT mice, IL-23 -/- mice developed significantly lower static compliance values and markedly reduced emphysematous changes on histological analyses after PPE instillation. These changes were associated with lower levels of IL-17A and fewer Th17 cells in the lung. The neutrophilia seen in bronchoalveolar lavage fluid of WT mice was attenuated in IL-23 -/- mice, and the reduction was associated with decreased levels of keratinocyte-derived cytokine and macrophage inflammatory protein-2 in bronchoalveolar lavage fluid. Treatment with anti-IL-23p40 monoclonal antibody significantly attenuated PPE-induced emphysematous changes in the lungs of WT mice. These data identify the important contributions of IL-23 to the development of elastase-induced pulmonary inflammation and emphysema, mediated through an IL-23/IL-17 pathway. Targeting IL-23 in emphysema is a potential therapeutic strategy for delaying disease progression.

The aim of the current paper is to examine the impact of the enactment of constitutional prohibition in the United States in 1920 on total homicides, alcohol-related homicides and non-alcohol-related homicides in Chicago. Data are drawn from the Chicago Historical Homicide Project, a data set chronicling 11 018 homicides in Chicago between 1870 and 1930. Interrupted time-series and autoregression integrated moving average (ARIMA) models are employed to examine the impact of prohibition on three separate population-adjusted homicide series. All models control for potential confounding from World War I demobilization and from trend data drawn from Wesley Skogan's Time-Series Data from Chicago. Total and non-alcohol-related homicide rates increased during prohibition by 21% and 11%, respectively, while alcohol-related homicides remained unchanged. For other covariates, alcohol-related homicides were related negatively to the size of the Chicago police force and positively to police expenditures and to the proportion of the Chicago population aged 21 years and younger. Non-alcohol-related homicides were related positively to police expenditures and negatively to the size of the Chicago police force. While total and non-alcohol-related homicides in the United States continued to rise during prohibition, a finding consistent with other studies, the rate of alcohol-related homicides remained unchanged. The divergent impact of prohibition on alcohol- and non-alcohol-related homicides is discussed in relation to previous studies of homicide in this era.

In the twentieth century, race-based residential and commercial segregation that supported racial oppression and inequality became an elemental characteristic of urban black communities. Conflict-ridden, black-white relationships were common. However, the Chicago Defender Charities, Inc., the entity that sponsors the largest African American parade in the country and that emerged in 1947, embodied a tradition of charitable giving, self-help, and community service initiated in 1921 by Chicago Defender newspaper founder and editor, Robert S. Abbott. The foundation of this charitable tradition matured as a result of an early and sustained collaboration between Chicago’s white-owned Regal Theater and the black-owned Chicago Defender newspaper. Thus, in segregated African American communities, black and white commercial institutions, under certain conditions, were able to find important points of collaboration to uplift the African American communities of which they were a part.

Role of the IL-6 Gene in the Etiopathogenesis of Idiopathic Scoliosis

Full Text Available Scoliotic human nuclei pulposi can respond to exogenous proinflammatory stimuli by secreting increased amounts of interleukin-6 (IL-6. The G/C polymorphism of the promoter region of IL-6 gene influences levels and functional activity of the IL-6 protein. We conducted a case-control study of eighty patients with idiopathic scoliosis (IS and one hundred sixty healthy unrelated gender-matched controls trying to investigate the association between IS and the IL-6 promoter polymorphism at -174 position (rs1800795 G/C in Bulgarian population. Molecular detection of the IL-6 genotypes was performed by amplification followed by restriction technology. The statistical analysis was performed by Pearson’s chi-squared test. Our case-control study revealed a statistically significant association between the IL-6 (-174 G/C functional polymorphism and susceptibility to IS. In addition, a significant association between the IL-6 (-174 G/C polymorphism and curve severity was detected. IL-6 gene could be considered as susceptibility and modifying factor of idiopathic scoliosis. The identification of molecular markers with diagnostic and prognostic value could be useful for early detection of children at risk for the development of scoliosis and for prognosis of the risk for a rapid deformity progression. That would facilitate the therapy decisions and early stage treatment of the patient with the least invasive procedures.

Identification and Characterization of a Novel IL-4 Receptor α Chain (IL-4Rα Antagonist to Inhibit IL-4 Signalling

Directory of Open Access Journals (Sweden)

Nayyar Ahmed

2015-05-01

Full Text Available Background/Aims: In recent times, allergy has become a financial, physical and psychological burden to the society as a whole. In allergic cascades, cytokine IL-4 binds to IL-4 receptor (IL-4R, consequently producing allergen-specific IgE antibodies by B cells. In addition, among other functions, IL-4 is also responsible for B and T cell proliferation and differentiation. Hence, characterization of novel antagonists that inhibit IL-4 signalling forms the overall aim of this study. Methods: Phage display was used to screen a random 12-mer synthetic peptide library with a human IL-4Rα to identify peptide candidates. Once identified, the peptides were commercially synthesized and used for in vitro immunoassays. Results: We have successfully used phage display to identify M13 phage clones that demonstrated specific binding to IL-4Rα. The peptide N1 was synthesized for use in ELISA, demonstrating significant binding to IL-4Rα and inhibiting interaction with cytokine IL-4. Furthermore, the peptide was tested in a transfected HEK-Blue IL-4 reporter cell line model, which produces alkaline phosphatase (AP. QUANTI-Blue, a substrate, breaks down in the presence of AP producing a blue coloration. Using this colorimetric analysis, >50% inhibition of IL-4 signalling was achieved. Conclusion: We have successfully identified and characterised a synthetic peptide antagonist against IL-4Rα, which effectively inhibits IL-4 interaction with the IL-4Rα in vitro. Since IL-4 interaction with IL-4Rα is a common pathway for many allergies, a prophylactic treatment can be devised by inhibiting this interaction for future treatment of allergies.

IL17 Mediates Pelvic Pain in Experimental Autoimmune Prostatitis (EAP.

Directory of Open Access Journals (Sweden)

Stephen F Murphy

Full Text Available Chronic pelvic pain syndrome (CPPS is the most common form of prostatitis, accounting for 90-95% of all diagnoses. It is a complex multi-symptom syndrome with unknown etiology and limited effective treatments. Previous investigations highlight roles for inflammatory mediators in disease progression by correlating levels of cytokines and chemokines with patient reported symptom scores. It is hypothesized that alteration of adaptive immune mechanisms results in autoimmunity and subsequent development of pain. Mouse models of CPPS have been developed to delineate these immune mechanisms driving pain in humans. Using the experimental autoimmune prostatitis (EAP in C57BL/6 mice model of CPPS we examined the role of CD4+T-cell subsets in the development and maintenance of prostate pain, by tactile allodynia behavioral testing and flow cytometry. In tandem with increased CD4+IL17A+ T-cells upon EAP induction, prophylactic treatment with an anti-IL17 antibody one-day prior to EAP induction prevented the onset of pelvic pain. Therapeutic blockade of IL17 did not reverse pain symptoms indicating that IL17 is essential for development but not maintenance of chronic pain in EAP. Furthermore we identified a cytokine, IL7, to be associated with increased symptom severity in CPPS patients and is increased in patient prostatic secretions and the prostates of EAP mice. IL7 is fundamental to development of IL17 producing cells and plays a role in maturation of auto-reactive T-cells, it is also associated with autoimmune disorders including multiple sclerosis and type-1 diabetes. More recently a growing body of research has pointed to IL17's role in development of neuropathic and chronic pain. This report presents novel data on the role of CD4+IL17+ T-cells in development and maintenance of pain in EAP and CPPS.

Lung CD8(+) T cells might contribute to progression of chronic obstructive pulmonary disease (COPD) indirectly via IFN-gamma production or directly via cytolysis, but evidence for either mechanism is largely circumstantial. To gain insights into these potential mechanisms, we analyzed clinically indicated lung resections from three human cohorts, correlating findings with spirometrically defined disease severity. Expression by lung CD8(+) T cells of IL-18R and CD69 correlated with severity, as did mRNA transcripts for perforin and granzyme B, but not Fas ligand. These correlations persisted after correction for age, smoking history, presence of lung cancer, recent respiratory infection, or inhaled corticosteroid use. Analysis of transcripts for killer cell lectin-like receptor G1, IL-7R, and CD57 implied that lung CD8(+) T cells in COPD do not belong to the terminally differentiated effector populations associated with chronic infections or extreme age. In vitro stimulation of lung CD8(+) T cells with IL-18 plus IL-12 markedly increased production of IFN-gamma and TNF-alpha, whereas IL-15 stimulation induced increased intracellular perforin expression. Both IL-15 and IL-18 protein expression could be measured in whole lung tissue homogenates, but neither correlated in concentration with spirometric severity. Although lung CD8(+) T cell expression of mRNA for both T-box transcription factor expressed in T cells and GATA-binding protein 3 (but not retinoic acid receptor-related orphan receptor gamma or alpha) increased with spirometric severity, stimulation of lung CD8(+) T cells via CD3epsilon-induced secretion of IFN-gamma, TNF-alpha, and GM-CSF, but not IL-5, IL-13, and IL-17A. These findings suggest that the production of proinflammatory cytokines and cytotoxic molecules by lung-resident CD8(+) T cells contributes to COPD pathogenesis.

IL-22 Defect During Streptococcus pneumoniae Infection Triggers Exacerbation of Chronic Obstructive Pulmonary Disease

2015-11-01

Full Text Available Progression of chronic obstructive pulmonary disease (COPD is linked to episodes of exacerbations caused by bacterial infections due to Streptococcus pneumoniae. Our objective was to identify during COPD, factors of susceptibility to bacterial infections among cytokine network and their role in COPD exacerbations. S. pneumoniae was used to sub-lethally challenge mice chronically exposed to air or cigarette smoke (CS and to stimulate peripheral blood mononuclear cells (PBMC from non-smokers, smokers and COPD patients. The immune response and the cytokine production were evaluated. Delayed clearance of the bacteria and stronger lung inflammation observed in infected CS-exposed mice were associated with an altered production of IL-17 and IL-22 by innate immune cells. This defect was related to a reduced production of IL-1β and IL-23 by antigen presenting cells. Importantly, supplementation with recombinant IL-22 restored bacterial clearance in CS-exposed mice and limited lung alteration. In contrast with non-smokers, blood NK and NKT cells from COPD patients failed to increase IL-17 and IL-22 levels in response to S. pneumoniae, in association with a defect in IL-1β and IL-23 secretion. This study identified IL-17 and IL-22 as susceptibility factors in COPD exacerbation. Therefore targeting such cytokines could represent a potent strategy to control COPD exacerbation.

Bridge populations can play a central role in the spread of human immunodeficiency virus (HIV) by providing transmission links between higher and lower prevalence populations. While social network methods are well suited to the study of bridge populations, analyses tend to focus on dyads (i.e., risk between drug and/or sex partners) and ignore bridges between distinct subpopulations. This study takes initial steps toward moving the analysis of sexual network linkages beyond individual and risk group levels to a community level in which Chicago's 77 community areas are examined as subpopulations for the purpose of identifying potential bridging communities. Of particular interest are "hidden" bridging communities; that is, areas with above-average levels of sexual ties with other areas but whose below-average AIDS prevalence may hide their potential importance for HIV prevention. Data for this analysis came from the first wave of recruiting at the Chicago Sexual Acquisition and Transmission of HIV Cooperative Agreement Program site. Between August 2005 through October 2006, respondent-driven sampling was used to recruit users of heroin, cocaine, or methamphetamine, men who have sex with men regardless of drug use, the sex partners of these two groups, and sex partners of the sex partners. In this cross-sectional study of the sexual transmission of HIV, participants completed a network-focused computer-assisted self-administered interview, which included questions about the geographic locations of sexual contacts with up to six recent partners. Bridging scores for each area were determined using a matrix representing Chicago's 77 community areas and were assessed using two measures: non-redundant ties and flow betweenness. Bridging measures and acquired immunodeficiency syndrome (AIDS) case prevalence rates were plotted for each community area on charts representing four conditions: below-average bridging and AIDS prevalence, below-average bridging and above

Functional Implications of the IL-23/IL-17 Immune Axis in Schizophrenia.

Debnath, Monojit; Berk, Michael

2017-12-01

The aetiology of schizophrenia seems to stem from complex interactions amongst environmental, genetic, metabolic, immunologic and oxidative components. Chronic low-grade inflammation has been persistently linked to schizophrenia, and this has primarily been based on the findings derived from Th1/Th2 cytokine balance. While the IL-23/IL-17 axis plays crucial role in the pathogenesis of several immune-mediated disorders, it has remained relatively unexplored in neuropsychiatric disorders. Altered levels of cytokines related to IL-23/IL-17 axis have been observed in schizophrenia patients in a few studies. In addition, other indirect factors known to confer schizophrenia risk like complement activation and altered gut microbiota are shown to modulate the IL-23/IL-17 axis. These preliminary observations provide crucial clues about the functional implications of IL-23/IL-17 axis in schizophrenia. In this review, an attempt has been made to highlight the biology of IL-23/IL-17 axis and its relevance to schizophrenia risk and pathogenesis. Given the pathogenic potential of the IL-23/IL-17 axis, therapeutic targeting of this axis may be a promising approach to benefit patients suffering from this devastating disorder.

The aim of this review was to examine current knowledge of the role of interleukin-6 (IL-6) in apical periodontitis (AP) pathogenesis as an inflammatory or pro-inflammatory cytokine. It also looked at whether IL-6 could serve as a measure for differential diagnosis or as a biomarker that can further predict the progression of bone resorption. A systematic review relating to AP and IL-6 was made via PubMed, BIOSIS, Cochrane, EMBASE and Web of Science databases using keywords and controlled vocabulary. Two independent reviewers first screened titles and abstracts and then the full texts. The reference lists of the identified publications were examined for additional titles. Eighteen papers were studied in total. In vitro studies (n = 6) revealed that IL-6 is present in AP, and its levels are proportional to the size of the periapical lesions. Neutrophils and macrophages resident in these lesions can produce IL-6 in vitro after a bacterial stimulus. Animal studies (n = 5) showed that IL-6 is present in AP and that osteoblasts can produce IL-6 in vivo. On the other hand, two studies using IL-6 knockout mice revealed larger periapical lesions when compared with control groups, demonstrating IL-6's role as an anti-inflammatory cytokine. In human studies (n = 7), IL-6 was identified in AP, and its levels were higher in symptomatic, epithelialized and large lesions than in asymptomatic and small lesions. These data lead to the conclusion that IL-6 may play a pro-inflammatory role, increasing its levels and reabsorbing bone in the presence of infections. When IL-6 is not present, other cytokines such as IL-1 and TNF-α induce bone resorption. Further studies about the relationship between AP development and the cytokine network must be performed to establish the exact role of each cytokine in the inflammatory process. © 2013 International Endodontic Journal.

Full Text Available Household contacts of diagnostically established tuberculosis (TB patients are highly susceptible to disease development. It is surmised that cytokines perhaps play a synergistic and a prognostic role in the activation of the otherwise latent infection in these house hold contacts. Evaluation of the cytokines and any of their inherent polymorphisms might provide a useful diagnostic tool in evaluating the immune regulation and the progression of the disease. The cytokines thus released in a paracrine manner in serum may also provide an indirect measure of the cytokine function.The present study was aimed to evaluate the levels of TNF-α, IL-10 & IL-6 cytokines and their correlation with genotype variants amongst tuberculosis patients and their household contacts.The cytokine levels were estimated in serum by enzyme-linked immunosorbent assay (ELISA and their polymorphisms were studied by amplification refractory mutation system polymerase chain reaction (ARMs PCR in active pulmonary tuberculosis patients (APTB = 150, household contacts (HHC = 190, and healthy controls (HC = 150.The median values of TNF-α cytokine were significantly high among APTB and HHC compared to HCs (P< 0.0001 and 0.0001. IL-6 levels also were elevated among APTB compared to HHC and HC, and a significant difference was observed between APTB and HHC at P<0.0001; APTB & HC at P< 0.04; HHC & HC at P< 0.01. The IL-10 levels were low in APTB compared to HHC and HCs and no significant difference was observed. TNF-α/IL-10 ratio was significant and indicated Th1 predominance in APTB and HHC. IL-6/IL-10 showed pronounced Th1 expression in APTB and Th2 in HHC and HC. The ROC analysis indicated that both IL-10 and IL-6 can be used to decide the risk of exposed individual to a disease. The results of multivariate analysis indicate that IL-10 (-1082 GA genotype was significantly associated with p<0.028 in APTB. No significant association was observed between genotypes, other serum

Full Text Available Respiratory virus infections, such as influenza, typically induce a robust type I (pro-inflammatory cytokine immune response, however, the production of type 2 cytokines has been observed. Type 2 cytokine production during respiratory virus infection is linked to asthma exacerbation; however, type 2 cytokines may also be tissue protective. Interleukin (IL-5 is a prototypical type 2 cytokine that is essential for eosinophil maturation and egress out of the bone marrow. However, little is known about the cellular source and underlying cellular and molecular basis for the regulation of IL-5 production during respiratory virus infection. Using a mouse model of influenza virus infection, we found a robust transient release of IL-5 into infected airways along with a significant and progressive accumulation of eosinophils into the lungs, particularly during the recovery phase of infection, i.e. following virus clearance. The cellular source of the IL-5 was group 2 innate lymphoid cells (ILC2 infiltrating the infected lungs. Interestingly, the progressive accumulation of eosinophils following virus clearance is reflected in the rapid expansion of c-kit⁺ IL-5 producing ILC2. We further demonstrate that the enhanced capacity for IL-5 production by ILC2 during recovery is concomitant with the enhanced expression of the IL-33 receptor subunit, ST2, by ILC2. Lastly, we show that NKT cells, as well as alveolar macrophages (AM, are endogenous sources of IL-33 that enhance IL-5 production from ILC2. Collectively, these results reveal that c-kit⁺ ILC2 interaction with IL-33 producing NKT and AM leads to abundant production of IL-5 by ILC2 and accounts for the accumulation of eosinophils observed during the recovery phase of influenza infection.

Full Text Available Abstract Background Women with Human Papilloma Virus (HPV persistence are characterized by high levels of IL-10 at cervix. We have determined whether polymorphisms of IL-10 gene promoter might be associated with increased risk of squamous intraepithelial cervical lesions (SICL and whether exist significative differences of IL-10 mRNA expression at cervix and systemic and serum IL-10 protein between SICL cases and non-Cervical Lesions (NCL. Methods Peripheral blood samples from SICL (n = 204 and NCL (n = 166 were used to detect IL-10 promoter polymorphisms at loci -592A/C (rs1800872, -819C/T (rs1800871, -1082A/G (rs1800896, -1352A/G (rs1800893, by allelic discrimination and to evaluate serum IL-10 protein. Cervical epithelial scrapings from NCL and biopsies from SICLs were used for HPV-typing and to evaluate IL-10 mRNA expression level. The systemic and local IL-10 mRNA expression levels were measured by real time-PCR. Genotypic and allelic frequencies of the selected polymorphisms were analyzed by logistic regression, adjusting by age and HPV-genotype, to determine the association with SICL. Results No significant differences were found between genotype frequencies at loci −819, -1082, and −1352. Individuals carrying at least one copy of risk allele A of polymorphism −592 had a two-fold increased risk of developing SICL [adjusted odds ratio (OR, 2.02 (95% CI, 1.26-3.25, p = 0.003], compared to NCL. The IL-10 mRNA expression and serum IL-10 protein, were significantly higher in SICL cases (p  Conclusions The −592 polymorphism is associated with increased risk of SICL and can serve as a marker of genetic susceptibility to SICL among Mexican women. According to IL-10 levels found in SICL, IL-10 can be relevant factor for viral persistence and progression disease.

Full Text Available Background. We aimed to examine whether proinflammatory cytokines participated in prostate cancer (PCa development and progression promoted by high-fat diet (HFD. Methods. TRAMP (transgenic adenocarcinoma mouse prostate mice were randomly divided into two groups: normal diet group and HFD group. Mortality rate and tumor formation rate were examined. TRAMP mice were sacrificed and sampled on the 20th, 24th, and 28th week, respectively. Levels of proinflammatory cytokines, including IL-1α, IL-1β, IL-6, and TNF-α, were tested by FlowCytomix. Prostate tissue of TRAMP mice was used for histology study. Results. A total of 13 deaths of TRAMP mice were observed, among which 3 (8.33% were from the normal diet group and 10 (27.78% from the HFD group. The mortality rate of TRAMP mice from HFD group was significantly higher than that of normal diet group (P=0.032. Tumor formation rate at 20th week of age of HFD group was significantly higher than that of normal diet group (P=0.045. Proinflammatory cytokines levels, including IL-1α, IL-1β, IL-6, and TNF-α, were significantly higher in HFD TRAMP mice. Conclusions. HFD could promote TRAMP mouse PCa development and progression with elevated proinflammatory cytokines levels. Proinflammatory cytokines could contribute to PCa development and progression promoted by HFD.

Full Text Available Objective: Weight loss is a near societal obsession and many diet programs use significant calorie restriction (CR including fasting/short term starvation to generate rapid effects. Fasting is also a well-recognized cause of immunosuppression especially within the innate immune system. In this study, we sought to determine if the IL-1 arm of the neuroimmune system was down-regulated by a 24 hr fast and how fasting might generate this effect. Design: Mice were allowed ad libitum access to food or had food withheld for 24 hrs. Expression of the endogenous IL-1 antagonists IL-1 receptor type 2 (IL-1R2 and IL-1 receptor antagonist (IL-1RA were determined as were sickness behaviors before and after IL-1 administration.Results: Fasting markedly increased gene expression of IL-1R2 (83-fold in adipose tissue, 9.5-fold in liver and IL-1RA (68-fold in liver. Fasted mice were protected from IL-1-induced weight loss, hypoglycemia, loss of locomotor and social anxiety. These protections were coupled to a large positive interaction of fasting and IL-1 on IL-1R2 gene expression in adipose tissue and liver (2.6-fold and 1.6-fold, respectively. Fasting not only increased IL-1RA and IL-1R2 protein 2.5-fold and 3.2-fold, respectively, in liver; but also increased IL-1R2 1.8-fold in adipose tissue. Fasting, in turn, triggered a 2.4-fold increase in plasma free-fatty acids (FFAs and a 2.1-fold increase in plasma corticosterone. Inhibition, of glucocorticoid action with mifepristone did not impact fasting-dependent IL-1R2 or IL-1RA gene expression. Administration of the FFA, palmitate, to mice increased liver IL-1R2 and IL-1RA gene expression by 14-fold and 11-fold, respectively. Conclusion: These findings indicate that fasting augments expression of endogenous IL-1 antagonists inducing IL-1 resistance. Fasting-induced increases in plasma FFAs appears to be a signal that drives immunosuppression during fasting/short term starvation.

The Origin of the ‘Chicago Method’ Excavation Techniques: Contributions of William Nickerson and Frederick Starr

Full Text Available What were the origins of the ‘Chicago method’ of scientific excavation? What is it and how did it get that name? Does its origin predate its popular employment at excavations in the USA during the 1930s and 1940s, and go back to institutional competition between Frederic Ward Putnam of the Field Museum and Frederick Starr of the University of Chicago? Or was it the result of the fieldwork of avocational archaeologist and one of Putnam’s first students, William Baker Nickerson, who implemented it as the basis of his fieldwork, and proved its efficacy, for many years before he retired in 1921? Nickerson’s detailed notes on the results of his thorough stratigraphic excavation techniques, used at many archaeological sites in Iowa, Illinois, Ohio and Minnesota, were passed on to the first University of Chicago field party doing archaeological work in Illinois, that consequently became the foundations of the later ‘Chicago method’.

Increased blood cytokines is the main immunopathological process that were attributed to severe clinical outcomes in cases of influenza A/H3N2 virus infection. The study was aimed to investigate the polymorphisms of IL-1β, IL-10, IL-17, and IL-28 genes to find the possibility of their association with the clinical outcome of influenza A/H3N2 virus infection among the infected patients in Iran. This is a Case-Control study in which influenza A/H3N2 virus positive confirmed with real-time PCR were the cases. DNA samples from groups were genotyped for polymorphisms in rs16944 (IL-1β), rs1800872 (IL-10), rs2275913 (IL-17), and rs8099917 (IL-28). Confidence interval (95%CI) and Odds ratio (OR) were calculated. IL-17 rs2275913 (GG and AG) were associated with risk of infection with that were statistically significant (P rs16944) (GG) was associated with reduced risk of infection (P < 0.01, OR = 0.46). Genotype GG and GT of IL-10 (rs1800872) were associated with increased risk of infection with influenza A/H3N2 virus (P < 0.05, OR = 2.04-2.58). In addition, IL-28 (rs8099917) genotypes GG (P < 0.05, OR = 0.49) and TG (P < 0.05, OR = 0.59) were associated with reduced risk of ILI symptom while genotype TT (P < 0.01, OR = 4.31) was associated with increased risk of ILI symptom. The results of this study demonstrated that polymorphisms of genes involved in the inflammatory and anti-inflammatory process affect the outcome of disease caused by influenza A/H3N2 virus. Thorough insight on host immune response at the time of influenza A virus infection is required to ensure adequate patient care in the case of feature outbreaks. J. Med.

In this study, we investigated how pregnancy influences cytokine production in response to stimulation of the innate and the adaptive immune system, respectively. Peripheral blood mononuclear cells (PBMCs) from allergic (n = 44) and non-allergic (n = 36) women were collected at three time-points: during the third trimester, at delivery and at a non-pregnant state 2 years after delivery. The production of interleukin-1beta (IL-1beta), IL-6, IL-10 and IL-12 was measured by enzyme-linked immunosorbent assay (ELISA) or enzyme-linked immunospot assay (ELISPOT). The spontaneous cytokine production, and the response following stimulation with agents that primarily activate the adaptive part of the immune system [phytohaemagglutinin (PHA), allergen extracts from cat and birch], or lipopolysaccharide (LPS) that activate innate immunity was measured in vitro. There was a significantly higher spontaneous in vitro production of IL-1beta, IL-6 and IL-10 by PBMCs during pregnancy than 2 years after pregnancy, and this was not affected by the allergic status of the women. Conversely, in PHA-stimulated cell cultures there was a lower production of IL-10 and IL-12 during pregnancy than 2 years after pregnancy. LPS-induced IL-6 levels were significantly lower in PBMCs obtained during pregnancy than at 2 years after pregnancy. In addition, we made the interesting observation that in allergic women total immunoglobulin E (IgE) levels were significantly lower 2 years after pregnancy compared to the levels during pregnancy. Taken together, our results indicate that while atopic allergy in women does not have a substantial effect on cytokine production, pregnancy has an obvious effect on the immune system in terms of cytokine production as well as on the total IgE levels.

Structure of IL-22 Bound to Its High-Affinity IL-22R1 Chain

Energy Technology Data Exchange (ETDEWEB)

Jones, B.C.; Logsdon, N.J.; Walter, M.R. (UAB)

2008-09-29

IL-22 is an IL-10 family cytokine that initiates innate immune responses against bacterial pathogens and contributes to immune disease. IL-22 biological activity is initiated by binding to a cell-surface complex composed of IL-22R1 and IL-10R2 receptor chains and further regulated by interactions with a soluble binding protein, IL-22BP, which shares sequence similarity with an extracellular region of IL-22R1 (sIL-22R1). IL-22R1 also pairs with the IL-20R2 chain to induce IL-20 and IL-24 signaling. To define the molecular basis of these diverse interactions, we have determined the structure of the IL-22/sIL-22R1 complex. The structure, combined with homology modeling and surface plasmon resonance studies, defines the molecular basis for the distinct affinities and specificities of IL-22 and IL-10 receptor chains that regulate cellular targeting and signal transduction to elicit effective immune responses.

2017-11-04

Interleukin-17 (IL-17), a pleiotropic proinflammatory cytokine, is reported to be significantly generated by a distinct subset of CD4 + T-cells, upgrading cancer-elicited inflammation and preventing cancer cells from immune surveillance. T-helper (Th)17 cells produced from naive CD4 + T cells have recently been renowned and generally accepted, gaining eminence in cancer studies and playing the effective role in context of cancer. Th17 cells are the main source of IL-17-secreting cells, It was found that other cell types produced this cytokine as well, including Group 3 innate lymphoid cells (ILC3), δγT cells, invariant natural killer T (iNKT) cells, lymphoid-tissue inducer (LTi)-like cells and Natural killer (NK) cells. Th17-associated cytokines give impetus to tumor progression, or inducing angiogenesis and metastasis. This review demonstrates an understanding on how the pro- or antitumor function of Th17 cells and IL-17 may change cancer progression, leading to the appearance of complex and pivotal biologic activities in tumor.

The mechanisms of metastatic progression from hormonal therapy (HT) are largely unknown in luminal breast cancer. Here we demonstrate the enrichment of CD133(hi)/ER(lo) cancer cells in clinical specimens following neoadjuvant endocrine therapy and in HT refractory metastatic disease. We develop experimental models of metastatic luminal breast cancer and demonstrate that HT can promote the generation of HT-resistant, self-renewing CD133(hi)/ER(lo)/IL6(hi) cancer stem cells (CSCs). HT initially abrogates oxidative phosphorylation (OXPHOS) generating self-renewal-deficient cancer cells, CD133(hi)/ER(lo)/OXPHOS(lo). These cells exit metabolic dormancy via an IL6-driven feed-forward ER(lo)-IL6(hi)-Notch(hi) loop, activating OXPHOS, in the absence of ER activity. The inhibition of IL6R/IL6-Notch pathways switches the self-renewal of CD133(hi) CSCs, from an IL6/Notch-dependent one to an ER-dependent one, through the re-expression of ER. Thus, HT induces an OXPHOS metabolic editing of luminal breast cancers, paradoxically establishing HT-driven self-renewal of dormant CD133(hi)/ER(lo) cells mediating metastatic progression, which is sensitive to dual targeted therapy.

Recently, a number of reports have demonstrated that coexpression of therapeutic genes having different anticancer mechanisms is a more effective strategy for anticancer gene therapy than single gene expression. Saxatilin, a novel disintegrin from snake venom, has recently been shown to have potent antiangiogenic functions, such as inhibition of platelet aggregation, bFGF-induced proliferation of HUVEC, and vitronectin-induced smooth muscle cell migration. IL-12 is a well-known immune modulator that promotes Thl-type antitumor immune responses and inhibits angiogenesis as well. The saxatilin and/or IL-12 genes were transfected intratumorally into C57BL/6 mice carrying TC-1 transformed mouse lung endothelial cells by either lipofection or electroporation. The plasmids encoding saxatilin and IL-12 were administered to tumor tissues via novel cationic liposomes consisting of dimyristyl-glutamyl-lysine (DMKE). On the other hand, expression of the genes was also induced by electroporation after naked pDNA injection to the tumor tissues. Lipofection of saxatilin and/or IL-12 genes appeared to be slightly more effective in inhibition of tumor growth than electroporation of the same genes. Cotransfection of saxatilin and IL-12 genes was clearly more effective than individual administration of either gene. This result implies that cotransfection of saxatilin and IL-12 genes represents an innovative modality for anticancer gene therapy.

Purpose: To investigate the effect of radiotherapy (RT) on serum levels of interleukin-2 (IL-2), IL-4, IL-5, IL-6, tumor necrosis factor alpha (TNF-{alpha}), macrophage inflammatory protein-1-alpha (MIP-1-{alpha}) and leukemia inhibitory factor (LIF) in patients with prostate cancer. Methods and Materials: Forty eight patients with prostate cancer received three-dimensional conformal blocking radiation therapy with a linear accelerator. IL-2, IL-4, IL-5, IL-6, TNF-{alpha}, MIP-1-{alpha}, and LIF levels were measured by the related immunoassay kit 1 day before the beginning of RT and during RT at days 15 and 30. Results: The mean IL-2 values were elevated before and during the RT in contrast with those of IL-4, IL-5, IL-6, TNF-{alpha}, MIP-1-{alpha}, and LIF, which were within the normal range under the same conditions. Regarding markers IL-2, IL-4, IL-5, TNF-{alpha}, MIP-1-{alpha}, and LIF, comparisons among the three groups (before treatment and 15 and 30 days during RT) did not show significant differences. Although values were within the normal range, there was a significant rise in IL-6 levels at day 15 of RT (p = 0.0049) and a decline at day 30 to levels that were similar to those observed before RT. Conclusions: IL-6 appeared to peak after 15 days of RT before returning to pre-RT levels. In contrast, IL-2, IL-4, IL-5, TNF-{alpha}, MIP-1-{alpha}, and LIF levels were not sensitive to irradiation. The increased levels of IL-6 following RT without the concurrent elevation of other cytokines involved in the acute phase reaction did not suggest a classical inflammatory response to radiation exposure. Further studies should be designed to elucidate the role of IL-6 levels in patients with prostate cancer treated with RT.

IL-4 binds to a cell surface receptor complex that consists of the IL-4 binding protein (IL-4R alpha) and the gamma chain of the IL-2 receptor complex (gamma c). The receptors for IL-4 and IL-2 have several features in common; both use the gamma c as a receptor component, and both activate the Janus kinases JAK-1 and JAK-3. In spite of these similarities, IL-4 evokes specific responses, including the tyrosine phosphorylation of 4PS/IRS-2 and the induction of CD23. To determine whether sequences within the cytoplasmic domain of the IL-4R alpha specify these IL-4-specific responses, we transplanted the insulin IL-4 receptor motif (I4R motif) of the huIL-4R alpha to the cytoplasmic domain of a truncated IL-2R beta. In addition, we transplanted a region that contains peptide sequences shown to block Stat6 binding to DNA. We analyzed the ability of cells expressing these IL-2R-IL-4R chimeric constructs to respond to IL-2. We found that IL-4 function could be transplanted to the IL-2 receptor by these regions and that proliferative and differentiative functions can be induced by different receptor sequences.

Semi-invariant natural killer T (NKT) cells are thymus-derived innate lymphocytes that modulate microbial and tumour immunity as well as autoimmune diseases. These immunoregulatory properties of NKT cells are acquired during their development. Much has been learnt regarding the molecular and cellular cues that promote NKT cell development, yet how these cells are maintained in the thymus and the periphery and how they acquire functional competence are incompletely understood. We found that IL-15 induced several Bcl-2 family survival factors in thymic and splenic NKT cells in vitro. Yet, IL15-mediated thymic and peripheral NKT cell survival critically depended on Bcl-xL expression. Additionally, IL-15 regulated thymic developmental stage 2 (ST2) to ST3 lineage progression and terminal NKT cell differentiation. Global gene expression analyses and validation revealed that IL-15 regulated Tbx21 (T-bet) expression in thymic NKT cells. The loss of IL15 also resulted in poor expression of key effector molecules such as IFN-γ, granzyme A and C as well as several NK cell receptors in NKT cells. Taken together, our findings reveal a critical role for IL-15 in NKT cell survival, which is mediated by Bcl-xL, and effector differentiation, which is consistent with a role of T-bet in regulating terminal maturation.

In pulmonary paracoccidioidomycosis IL-10 deficiency leads to increased immunity and regressive infection without enhancing tissue pathology.

Directory of Open Access Journals (Sweden)

Tânia A Costa

Full Text Available BACKGROUND: Cellular immunity is the main defense mechanism in paracoccidioidomycosis (PCM, the most important systemic mycosis in Latin America. Th1 immunity and IFN-γ activated macrophages are fundamental to immunoprotection that is antagonized by IL-10, an anti-inflammatory cytokine. Both in human and experimental PCM, several evidences indicate that the suppressive effect of IL-10 causes detrimental effects to infected hosts. Because direct studies have not been performed, this study was aimed to characterize the function of IL-10 in pulmonary PCM. METHODOLOGY/PRINCIPAL FINDINGS: Wild type (WT and IL-10(-/- C57BL/6 mice were used to characterize the role of IL-10 in the innate and adaptive immunity against Paracoccidioides brasiliensis (Pb infection. We verified that Pb-infected peritoneal macrophages from IL-10(-/- mice presented higher phagocytic and fungicidal activities than WT macrophages, and these activities were associated with elevated production of IFN-γ, TNF-α, nitric oxide (NO and MCP-1. For in vivo studies, IL-10(-/- and WT mice were i.t. infected with 1×10(6 Pb yeasts and studied at several post-infection periods. Compared to WT mice, IL-10(-/- mice showed increased resistance to P. brasiliensis infection as determined by the progressive control of pulmonary fungal loads and total clearance of fungal cells from dissemination organs. This behavior was accompanied by enhanced delayed-type hypersensitivity reactions, precocious humoral immunity and controlled tissue pathology resulting in increased survival times. In addition, IL-10(-/- mice developed precocious T cell immunity mediated by increased numbers of lung infiltrating effector/memory CD4(+ and CD8(+ T cells. The inflammatory reactions and the production of Th1/Th2/Th17 cytokines were reduced at late phases of infection, paralleling the regressive infection of IL-10(-/- mice. CONCLUSIONS/SIGNIFICANCE: Our work demonstrates for the first time that IL-10 plays a

volunteers served to confirm initial findings. mRNA was analyzed by real-time reverse transcriptase polymerase chain reaction (PCR). RESULTS: We found elevated expression of interleukin (IL)-23 and IL-10 in untreated MS patients. IFN-beta therapy increased IL-10 and decreased IL-23 expression independently...... of the regulatory cytokine IL-10. The elevated IL-23 mRNA levels in MS patients are noteworthy in view of the newly discovered IL-23-driven Th17 T-cell subset, which is crucial in animal models of MS.

Ataxia-telangiectasia mutated (ATM) protein kinase regulates the DNA damage response (DDR) and is associated with cancer suppression. Here we report a cancer-promoting role for ATM. ATM depletion in metastatic cancer cells reduced cell migration and invasion. Transcription analyses identified a gene network, including the chemokine IL-8, regulated by ATM. IL-8 expression required ATM and was regulated by oxidative stress. IL-8 was validated as an ATM target by its ability to rescue cell migration and invasion defects in ATM-depleted cells. Finally, ATM-depletion in human breast cancer cells reduced lung tumors in a mouse xenograft model and clinical data validated IL-8 in lung metastasis. These findings provide insights into how ATM activation by oxidative stress regulates IL-8 to sustain cell migration and invasion in cancer cells to promote metastatic potential. Thus, in addition to well-established roles in tumor suppression, these findings identify a role for ATM in tumor progression.

IL-8 dictates glycosaminoglycan binding and stability of IL-18 in cystic fibrosis.

Dysregulation of airway inflammation contributes to lung disease in cystic fibrosis (CF). Inflammation is mediated by inflammatory cytokines, including IL-8, which illustrates an increase in biological half-life and proinflammatory activity when bound to glycosaminoglycans (GAGs). The aim of this project was to compare IL-8 and IL-18 for their relative stability, activity, and interaction with GAGs, including chondroitin sulfate, hyaluronic acid, and heparan sulfate, present in high quantities in the lungs of patients with CF. Bronchoalveolar lavage fluid was collected from patients with CF (n = 28), non-CF controls (n = 14), and patients with chronic obstructive pulmonary disease (n = 12). Increased levels of IL-8 and reduced concentrations of IL-18 were detected in bronchial samples obtained from CF individuals. The low level of IL-18 was not a defect in IL-18 production, as the pro- and mature forms of the molecule were expressed and produced by CF epithelial cells and monocytes. There was, however, a marked competition between IL-8 and IL-18 for binding to GAGs. A pronounced loss of IL-18 binding capacity occurred in the presence of IL-8, which displaced IL-18 from these anionic-matrices, rendering the cytokine susceptible to proteolytic degradation by neutrophil elastase. As a biological consequence of IL-18 degradation, reduced levels of IL-2 were secreted by Jurkat T lymphocytes. In conclusion, a novel mechanism has been identified highlighting the potential of IL-8 to determine the fate of other inflammatory molecules, such as IL-18, within the inflammatory milieu of the CF lung.

Objective: To study the role TNF-α, IL-1β, IL-6 and IL-8 played in the pathogenesis of coronary cardiac heart diseases. Methods: Serum levels of TNF-α, IL-1β, IL-6 and IL-8 levels were determined by chemiluminescence immunoassay in 32 patients with stable angina, 39 patients with acute myocardial infarction and 36 controls. Results: Serum TNF-α, IL-1β, IL-6 and IL-8 levels in all patients were higher than those in controls. Remarkably increased level were seen in acute myocardial infarction group. Difference between control and patient groups were: stable angina group TNF-α, p<0.05, IL-6, p<0.01 and IL-8, p<0.05; acute myocardial infarction group TNF-α, p<0.01, IL-1β, p<0.05, IL-6, p<0.001 and IL-8, p<0.001. Conclusion: There is close relationship between serum TNF-α, IL-1β, IL-6, IL-8 levels and development of coronary cardiac heart disease. They play an important role in the pathogenesis through mutual induction and synergistic actions

A man of his time: thorstein veblen and the university of chicago darwinists.

Raymer, Emilie J

2013-01-01

The Darwinian economic theory that Thorstein Veblen proposed and refined while he served as a professor of Political Economy at the University of Chicago from 1891 to 1906 should be assessed in the context of the community of Darwinian scientists and social scientists with whom Veblen worked and lived at Chicago. It is important to identify Veblen as a member of this broad community of Darwinian-inclined philosophers, physiologists, geologists, astronomers, and biologists at Chicago because Veblen's involvement with this circle suggests that the possible sources of his engagement with Darwinism extend beyond the pragmatists and Continental socialists to whom scholars have typically ascribed Veblen's Darwinian roots. Additionally, that an extensive community continued to use Darwinian evolutionary theory to construct new models of scientific and social scientific analysis at the turn of the twentieth century, a period during which Darwinism was purportedly in decline, suggests that the "eclipse of Darwinism" narrative has been overstated in literature about Darwinism's intellectual arc.

Interleukin (IL)-23 is a heterodimeric cytokine consisting of a novel p19 molecule and the p40 subunit of IL-12. Since secreted p40 can act as an antagonist for IL-12, we investigated whether p40 also inhibited IL-23-mediated immunological functions. p40 did not induce interferon (IFN)-γ or IL-17 production from splenocytes but impaired IL-23-induced cytokine production by competitive binding to the IL-23 receptors. Furthermore, a mixed population of murine colon carcinoma Colon 26 cells transduced with the p40 gene and those transduced with the IL-23 gene developed tumours in syngenic mice, whereas the IL-23-expressing Colon 26 cells were completely rejected. p40 also suppressed IFN-γ production of antigen-stimulated splenocytes and IL-23-mediated cytotoxic T-lymphocyte activities in the mice that rejected Colon 26 cells expressing IL-23. p40 can thereby antagonize IL-23 and is a possible therapeutic agent for suppression of IL-23 functions.

IL22/IL-22R pathway induces cell survival in human glioblastoma cells.

Directory of Open Access Journals (Sweden)

Hussein Akil

Full Text Available Interleukin-22 (IL-22 is a member of the IL-10 cytokine family that binds to a heterodimeric receptor consisting of IL-22 receptor 1 (IL-22R1 and IL-10R2. IL-22R expression was initially characterized on epithelial cells, and plays an essential role in a number of inflammatory diseases. Recently, a functional receptor was detected on cancer cells such as hepatocarcinoma and lung carcinoma, but its presence was not reported in glioblastoma (GBM. Two GBM cell lines and 10 primary cell lines established from patients undergoing surgery for malignant GBM were used to investigate the expression of IL-22 and IL-22R by using quantitative RT-PCR, western blotting and confocal microscopy studies. The role of IL-22 in proliferation and survival of GBM cell lines was investigated in vitro by BrdU and ELISA cell death assays. We report herein that the two subunits of the IL-22R complex are expressed on human GBM cells. Their activation, depending on exogenous IL-22, induced antiapoptotic effect and cell proliferation. IL-22 treatment of GBM cells resulted in increased levels of phosphorylated Akt, STAT3 signaling protein and its downstream antiapoptotic protein Bcl-xL and decreased level of phosphorylated ERK1/2. In addition, IL-22R subunits were expressed in all the 10 tested primary cell lines established from GBM tumors. Our results showed that IL-22R is expressed on GBM established and primary cell lines. Depending on STAT3, ERK1/2 and PI3K/Akt pathways, IL-22 induced GBM cell survival. These data are consistent with a potential role of IL-22R in tumorigenesis of GBM. Since endogenous IL-22 was not detected in all studied GBM cells, we hypothesize that IL-22R could be activated by immune microenvironmental IL-22 producing cells.

About 400 million people every year are estimated to contract dengue virus infection, which causes prolonged morbidity and sometimes mortality. Interleukin (IL)-28 and IL-29 are relatively newly discovered cytokines and play an important role in our immune defense against pathogens, especially for viral infection. In the present study, we investigated serum IL-28 and IL-29 expression and the relationship to clinical and laboratory parameters in patients with dengue virus infection. Adult patients with dengue (n = 45) and control group (n = 24) were included prospectively. Clinical symptoms and laboratory data were collected from every patient. We investigated IL-28 and IL-29 levels in serum by ELISA. The concentrations of serum IL-28 and IL-29 were significantly higher in subjects with dengue when compared to those of control group. The patients with higher serum IL-28 and IL-29 levels had significantly lower ALAT and peripheral blood neutrophil percentage, but higher peripheral platelet, total white blood cell (WBC), monocyte, and lymphocyte counts. Patients with higher serum IL-28 and IL-29 levels also had more flu-like symptoms, but less vomiting. Increased level of IL-28 and IL-29 was associated with better liver function, platelet and WBC numbers and clinical symptom in subjects with dengue and could potentially serve as a protective marker.

The financial crisis has brought il-legitimacy to the center of organizational life in the banking industry. It is unfortunate that little is known about how organizational il-legitimacy is experienced and handled by the people who spend most of their wakening hours at work within...... these organizations. The purpose of this paper is to address this gap of knowledge by exploring how members of a bankrupted bank experience and handle attributions of organizational il-legitimacy: to investigate the phenomenon from an inside perspective - in the eyes of the people who undergo it. The paper has...... an inductive approach and offers an explorative analysis based on an in-depth study of qualitative interviews with 20 members of a bankrupted bank. The analysis shows that in bankers’ narrations, (il)legitimacy is central: as a problem and as a solution. The paper contributes to extant knowledge on (il...

Exacerbation of CNS inflammation and neurodegeneration by systemic LPS treatment is independent of circulating IL-1 beta and IL-6

LENUS (Irish Health Repository)

Murray, Carol L

2011-05-17

Abstract Background Chronic neurodegeneration comprises an inflammatory response but its contribution to the progression of disease remains unclear. We have previously shown that microglial cells are primed by chronic neurodegeneration, induced by the ME7 strain of prion disease, to synthesize limited pro-inflammatory cytokines but to produce exaggerated responses to subsequent systemic inflammatory insults. The consequences of this primed response include exaggerated hypothermic and sickness behavioural responses, acute neuronal death and accelerated progression of disease. Here we investigated whether inhibition of systemic cytokine synthesis using the anti-inflammatory steroid dexamethasone-21-phosphate was sufficient to block any or all of these responses. Methods ME7 animals, at 18-19 weeks post-inoculation, were challenged with LPS (500 μg\\/kg) in the presence or absence of dexamethasone-21-phosphate (2 mg\\/kg) and effects on core-body temperature and systemic and CNS cytokine production and apoptosis were examined. Results LPS induced hypothermia and decreased exploratory activity. Dexamethasone-21-phosphate prevented this hypothermia, markedly suppressed systemic IL-1β and IL-6 secretion but did not prevent decreased exploration. Furthermore, robust transcription of cytokine mRNA occurred in the hippocampus of both ME7 and NBH (normal brain homogenate) control animals despite the effective blocking of systemic cytokine synthesis. Microglia primed by neurodegeneration were not blocked from the robust synthesis of IL-1β protein and endothelial COX-2 was also robustly synthesized. We injected biotinylated LPS at 100 μg\\/kg and even at this lower dose this could be detected in blood plasma. Apoptosis was acutely induced by LPS, despite the inhibition of the systemic cytokine response. Conclusions These data suggest that LPS can directly activate the brain endothelium even at relatively low doses, obviating the need for systemic cytokine stimulation to

Severe sepsis is a life-threatening disease that causes major morbidity and mortality. Catecholamines and glucocorticoids often have been used for the treatment of sepsis. Several recent studies have suggested a potential role of IL-17 during the development and progression of sepsis in small animal models. In this study, the cross-talk of catecholamines and glucocorticoids with members of the IL-17 family was investigated during sepsis in C57BL/6 mice. The concentrations in plasma of IL-17A, IL-17F, and the IL-17AF heterodimer all were increased greatly in mice after endotoxemia or cecal ligation and puncture as compared with sham mice. Surprisingly, when compared with IL-17A (487 pg/mL), the concentrations of IL-17F (2361 pg/mL) and the heterodimer, IL-17AF (5116 pg/mL), were much higher 12 hours after endotoxemia. After surgical removal of the adrenal glands, mice had much higher mortality after endotoxemia or cecal ligation and puncture. The absence of endogenous adrenal gland hormones (cortical and medullary) was associated with 3- to 10-fold higher concentrations of IL-17A, IL-17F, IL-17AF, and IL-23. The addition of adrenaline, noradrenaline, hydrocortisone, or dexamethasone to lipopolysaccharide-activated peritoneal macrophages dose-dependently suppressed the expression and release of IL-17s. The production of IL-17s required activation of c-Jun-N-terminal kinase, which was antagonized by both catecholamines and glucocorticoids. These data provide novel insights into the molecular mechanisms of immune modulation by catecholamines and glucocorticoids during acute inflammation.

Palmoplantar pustulosis (PPP) is a refractory, nonbacterial impetigo confined to the palms and soles. Its pathogenesis is still obscure, but it may be associated with the large eccrine sweat glands and pores of palmoplantar skin. PPP is considered to be a localized pustular psoriasis. Interleukin (IL)-8, IL-36γ and IL-36Ra play important roles in the pathogenesis of pustular psoriasis, but their role in PPP is unclear. To evaluate IL-8, IL-36γ and IL-36Ra expression in PPP, and their relationship with acrosyringia and pustule formation. mRNA expression was quantified in skin samples from patients with PPP (n = 7), patients with psoriasis vulgaris (PSV; n = 8) and healthy controls (HCs) (n = 6) by reverse-transcription-real-time PCR. Protein expression was characterized by immunohistochemistry (PPP, n = 17; PSV, n = 14; HCs, n = 12). Sweat ducts, including acrosyringia, were stained for epithelial membrane antigen (EMA). IL-8 mRNA and protein were markedly increased in PPP lesions compared with PSV lesions or HC skin. IL-36γ mRNA and protein were significantly more abundant in PPP lesions than in HC skin. IL-36Ra mRNA was significantly overexpressed in PPP lesions compared with HC skin, but there was no difference in IL-36Ra protein between PPP, PSV and HCs. IL-8 was abundantly expressed by neutrophils in PPP pustules, while IL36Ra was localized in the keratinocytes of PPP, PSV and HC skin. IL-36γ and EMA were colocalized in cells surrounding PPP pustules, and IL-36γ was also expressed in sweat duct cells in the dermis. IL-8, IL-36γ and IL-36Ra are overexpressed in PPP lesions. IL-8, IL-36γ and acrosyringia, rather than IL-36Ra, are associated with pustule formation in PPP. © 2018 British Association of Dermatologists.

Hematopoietic stem and progenitor cells with inactivated Fanconi anemia (FA) genes, FANCA and FANCC, are hypersensitive to inflammatory cytokines. One of these, tumor necrosis factor α (TNF-α), is also overproduced by FA mononuclear phagocytes in response to certain Toll-like receptor (TLR) agonists, creating an autoinhibitory loop that may contribute to the pathogenesis of progressive bone marrow (BM) failure and selection of TNF-α-resistant leukemic stem cell clones. In macrophages, the TNF-α overproduction phenotype depends on p38 mitogen-activated protein kinase (MAPK), an enzyme also known to induce expression of other inflammatory cytokines, including interleukin 1β (IL-1β). Reasoning that IL-1β might be involved in a like autoinhibitory loop, we determined that (1) TLR activation of FANCA- and FANCC-deficient macrophages induced overproduction of both TNF-α and IL-1β in a p38-dependent manner; (2) exposure of Fancc-deficient BM progenitors to IL-1β potently suppressed the expansion of multipotent progenitor cells in vitro; and (3) although TNF-α overexpression in FA cells is controlled posttranscriptionally by the p38 substrate MAPKAPK-2, p38-dependent overproduction of IL-1β is controlled transcriptionally. We suggest that multiple inflammatory cytokines overproduced by FANCA- and FANCC-deficient mononuclear phagocytes may contribute to the progressive BM failure that characterizes FA, and that to achieve suppression of this proinflammatory state, p38 is a more promising molecular therapeutic target than either IL-1β or TNF-α alone.

Multiple mosquito-borne parasites cocirculate in nature and potentially interact. To understand the community of parasites cocirculating with West Nile virus (WNV), we screened the bloodmeal content of Culex pipiens L. mosquitoes for three common types of hemoparasites. Blood-fed Cx. pipiens were collected from a WNV-epidemic area in suburban Chicago, IL, from May to September 2005 through 2010. DNA was extracted from dissected abdomens and subject to PCR and direct sequencing to identify the vertebrate host. RNA was extracted from the head or thorax and screened for WNV using quantitative reverse transcriptase PCR. Seventy-nine engorged females with avian host origin were screened using PCR and amplicon sequencing for filarioid nematodes, Haemosporida, and trypanosomatids. Filarioid nematodes were identified in 3.8% of the blooded abdomens, Plasmodium sp. in 8.9%, Haemoproteus in 31.6%, and Trypanosoma sp. in 6.3%. The sequences from these hemoparasite lineages were highly similar to sequences from birds in prior studies in suburban Chicago. Overall, 50.6% of blood-fed Culex pipiens contained hemoparasite DNA in their abdomen, presumably from current or prior bloodmeals. Additionally, we detected hemoparasite DNA in the blooded abdomen of three of 10 Cx. pipiens infected with WNV. © The Authors 2015.

Chronic inflammation has been associated with the development and progression of human cancers including prostate cancer. The exact role of the inflammatory Th17-IL-17 pathway in prostate cancer remains unknown. In this study, we aimed to determine the importance of Th17 cells and IL-17 in a Pten-null prostate cancer mouse model. The Pten-null mice were treated by Th17 inhibitor SR1001 or anti-mouse IL-17 monoclonal antibody from 6 weeks of age up to 12 weeks of age. For SR1001 treatment, the mice were injected intraperitoneally (i.p.) twice a day with vehicle or SR1001, which was dissolved in a dimethylsulfoxide (DMSO) solution. All mice were euthanized for necropsy at 12 weeks of age. For IL-17 antibody treatment, the mice were injected intravenously (i.v.) once every two weeks with control IgG or rat anti-mouse IL-17 monoclonal antibody, which was dissolved in PBS. The injection time points were at 6, 8, and 10 weeks old. All mice were analyzed for the prostate phenotypes at 12 weeks of age. We found that either SR1001 or anti-IL-17 antibody treatment decreased the formation of micro-invasive prostate cancer in Pten-null mice. The SR1001 or anti-IL-17 antibody treated mouse prostates had reduced proliferation, increased apoptosis, and reduced angiogenesis, as well as reduced inflammatory cell infiltration. By assessing the epithelial-to-mesenchymal transition (EMT) markers, we found that SR1001 or anti-IL-17 antibody treated prostate tissues had weaker EMT phenotype compared to the control treated prostates. These results demonstrated that Th17-IL-17 pathway plays a key role in prostate cancer progression in Pten-null mice. Targeting Th17-IL-17 pathway could prevent micro-invasive prostate cancer formation in mice. Prostate 77:888-899, 2017. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

The regulation of skeletal muscle protein turnover during the progression of cancer cachexia in the Apc(Min/+ mouse.

Directory of Open Access Journals (Sweden)

Full Text Available Muscle wasting that occurs with cancer cachexia is caused by an imbalance in the rates of muscle protein synthesis and degradation. The Apc(Min/+ mouse is a model of colorectal cancer that develops cachexia that is dependent on circulating IL-6. However, the IL-6 regulation of muscle protein turnover during the initiation and progression of cachexia in the Apc(Min/+ mouse is not known. Cachexia progression was studied in Apc(Min/+ mice that were either weight stable (WS or had initial (≤5%, intermediate (6-19%, or extreme (≥20% body weight loss. The initiation of cachexia reduced %MPS 19% and a further ∼50% with additional weight loss. Muscle IGF-1 mRNA expression and mTOR targets were suppressed with the progression of body weight loss, while muscle AMPK phosphorylation (Thr 172, AMPK activity, and raptor phosphorylation (Ser 792 were not increased with the initiation of weight loss, but were induced as cachexia progressed. ATP dependent protein degradation increased during the initiation and progression of cachexia. However, ATP independent protein degradation was not increased until cachexia had progressed beyond the initial phase. IL-6 receptor antibody administration prevented body weight loss and suppressed muscle protein degradation, without any effect on muscle %MPS or IGF-1 associated signaling. In summary, the %MPS reduction during the initiation of cachexia is associated with IGF-1/mTOR signaling repression, while muscle AMPK activation and activation of ATP independent protein degradation occur later in the progression of cachexia. IL-6 receptor antibody treatment blocked cachexia progression through the suppression of muscle protein degradation, while not rescuing the suppression of muscle protein synthesis. Attenuation of IL-6 signaling was effective in blocking the progression of cachexia, but not sufficient to reverse the process.

Chemokines and their receptors are involved in oncogenesis and in tumor progression, invasion, and metastasis. Various chemokines also promote cell proliferation and resistance to apoptosis of stressed cells. The chemokine CXCL8, also known as interleukin-8 (IL-8), is a proinflammatory molecule that has functions within the tumor microenvironment. Deregulation of IL-8 signaling is shown to play pivotal roles in tumorigenesis and progression. Mallory-Denk Bodies (MDBs) are prevalent in various liver diseases including alcoholic hepatitis (AH) and are formed in mice livers by feeding DDC. By comparing AH livers where MDBs had formed with normal livers, there were significant changes of IL-8 signaling by RNA sequencing (RNA-Seq) analyses. Real-time PCR analysis of CXCR2 further shows a 6-fold up-regulation in AH livers and a 26-fold up-regulation in the livers of DDC re-fed mice. IL-8 mRNA was also significantly up-regulated in AH livers and DDC re-fed mice livers. This indicates that CXCR2 and IL-8 may be crucial for liver MDB formation. MDB containing balloon hepatocytes in AH livers had increased intensity of staining of the cytoplasm for both CXCR2 and IL-8. Overexpression of IL-8 leads to an increase of the mitogen activated protein kinase (MAPK) cascade and exacerbates the inflammatory cycle. These observations constitute a demonstration of the altered regulation of IL-8 signaling in the livers of AH and mice fed DDC where MDBs formed, providing further insight into the mechanism of MDB formation mediated by IL-8 signaling in AH.

Antipsychotics with high weight gain-inducing propensities influence the expression of immune and neurotrophin genes, which have been independently related to obesity indices. Thus, we investigated whether variants in the genes encoding interleukin (IL)-1β, IL-2, and IL-6 and brain-derived neurotrophic factor (BDNF) Val66Met are associated with antipsychotic-induced weight gain (AIWG). Nineteen polymorphisms were genotyped using Taqman(®) assays in 188 schizophrenia patients on antipsychotic treatment for up to 14 weeks. Mean weight change (%) from baseline was compared across genotypic groups using analysis of covariance (ANCOVA). Epistatic effects between cytokine polymorphisms and BDNF Val66Met were tested using Model-Based Multifactor Dimensionality Reduction. In European patients, IL-1β rs16944*GA (P = 0.013, Pcorrected = 0.182), IL-1β rs1143634*G (P = 0.001, Pcorrected = 0.014), and BDNF Val66Met (Val/Val, P = 0.004, Pcorrected = 0.056) were associated with greater AIWG, as were IL-1β rs4849127*A (P = 0.049, Pcorrected = 0.784), and IL-1β rs16944*GA (P = 0.012, Pcorrected = 0.192) in African Americans. BDNF Val66Met interacted with both IL-1β rs13032029 (Val/Met+ TT, PPerm = 0.029), and IL-6 rs2069837 (Val/Val+ AA, PPerm = 0.021) in Europeans, in addition to IL-1β rs16944 (Val/Val+ GA, PPerm = 0.006) in African Americans. SNPs across IL-1β and BDNF Val66Met may influence AIWG. Replication of these findings in larger, independent samples is warranted.

Interleukin-6 (IL-6) plays a crucial role in the pathogenesis of rheumatoid arthritis (RA). Both fulfillment of remission criteria and assessment of other methods of evaluation of RA are important for preventing joint damage progression. Measurement of serum IL-6 concentrations has been reported to be useful for monitoring RA disease activity. However, it takes at least 4-5h to measure serum IL-6 concentrations using traditional methods, which limits its utility during routine assessment in daily clinical practice settings. We established a novel method that enables measurement of serum IL-6 within 24min and requires a very small blood volume. We investigated the accuracy and efficacy of this system in RA patients. One hundred fifty blood samples collected from 76 patients were measured using the two systems. We first developed the prototype of the Human IL-6 RAYFAST. Then, we examined the correlation between the prototype RAYFAST and chemiluminescent enzyme immunoassay (CLEIA) methods. Finally, we compared IL-6 concentrations and clinical parameters using both systems. The correlation between RAYFAST (x) and CLEIA (y) for IL-6 was y=0.895x-5.94, r=0.941 (p<0.0001). Serum IL-6 concentrations in RAYFAST correlated with DAS28-CRP (r=0.372, p<0.05) and DAS28-ESR (r=0.397, p<0.01). Serum IL-6 concentrations in CLEIA correlated with DAS28-CRP (r=0.313, p<0.001) and DAS28-ESR (r=0.353, p<0.001). This new cytokine quick measure system is as accurate as CLEIA methods. Serum IL-6 concentrations can be measured in 24min using the prototype RAYFAST. It might be usable in the daily clinical practice setting, thereby contributing to improved RA management.

Full Text Available Background: Neonates with the diagnosis of respiratory distress syndrome (RDS were studied to investigate possible associations between cytokine levels at birth and developing severe RDS or chronic lung disease (CLD. Materials and Methods: This was a cross-sectional study on serum and bronchoalveolar lavage (BAL samples collected within hours of birth from infants with moderate and severe RDS. Twenty infants with moderate RDS and 20 infants with severe RDS were studied. RDS was diagnosed on the basis of radiographic findings, respiratory distress, and an increasing oxygen requirement. RDS severity was graded based on the radiological findings and Downe's Score. CLD was diagnosed when infants were still on supplemented O2by at least 28 days of age. Levels of the cytokines interleukin (IL-1β, IL-6, IL-8, IL-10, and tumor necrosis factor alpha were measured using enzyme-linked immunosorbent assay. “Statistical analysis was performed using the SPSS for Windows, (SPSS Inc., Chicago, IL, USA.” Results: Levels of the proinflammatory cytokines IL-8 and IL-1β were significantly higher in BAL of infants with severe RDS than those with moderate RDS (P = 0.007 and P= 0.02, respectively. IL-8 levels were also significantly higher in BAL and serum of infants who later progressed to CLD than in those who did not (P = 0.03 for both. The IL-8/IL-10 cytokine ratio was significantly higher in the BAL of severe RDS infants than in moderate RDS (P = 0.01 and in the serum of infants who progressed to CLD than in those who did not (P = 0.03. Conclusion: Levels of IL-8 and the IL-8/IL-10 ratio measured soon after birth were associated with severity of RDS as well as progression to CLD. Early measurement of cytokines levels and ratios may contribute to the prognosis and management of RDS and CLD.

TNF-α is a diabetogenic cytokine associated with adverse outcomes during pregnancy that can be counterbalanced by IL-10. We have investigated IL-10 and TNF-α balance at maternal and placental levels in hyperglycemia-associated pregnancies. One hundred and ninety-two pregnant women participated, which included normoglycemic women (ND) and women with mild gestational hyperglycemia (MGH), gestational diabetes mellitus (GDM) and type 2 diabetes mellitus (DM2). Maternal plasma and placental tissue IL-10 and TNF-α levels were measured by ELISA and placental TNF-α was also immunolocalized. Maternal plasma TNF-α levels were highest in GDM (p=0.0190), whereas TNF-α levels were highest in placental tissues in DM2 (p=0.0095). Immunohistochemistry also showed strong reactivity with anti-TNF-α antibody in the villous structures in the DM2 group. Conversely, IL-10 levels were lowest in maternal plasma of the DM2 group (p=0.0228). The TNF-α/IL-10 ratio in maternal plasma progressively increased with the severity of hyperglycemia (pDM2 group (p=0.0150). In both, plasma and placenta, TNF-α/IL-10 ratio were correlated with mean maternal glycemia and HbA1c levels. Alterations of placenta and serum TNF-α/IL-10 balance with predominance of TNF-α were correlated with the severity of hyperglycemia during gestation. This association may offer insight into the pathogenesis of gestational hyperglycemia and associated pregnancy outcomes. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Highlights: → Curcumin inhibits CD4 + T-lymphocyte proliferation. → Curcumin inhibits interleukin-2 (IL-2) synthesis and CD25 expression by CD4 + T-lymphocytes. → Curcumin interferes with IL-2 receptor signaling by inhibiting JAK3 and STAT5 phosphorylation. → IL-2-dependent regulatory T-lymphocyte function and Foxp3 expression is downregulated by curcumin. -- Abstract: Curcumin (diferulomethane) is the principal curcuminoid in the spice tumeric and a potent inhibitor of activation-induced T-lymphocyte proliferation; however, the molecular basis of this immunosuppressive effect has not been well studied. Here we show that micromolar concentrations of curcumin inhibited DNA synthesis by mouse CD4 + T-lymphocytes, as well as interleukin-2 (IL-2) and CD25 (α chain of the high affinity IL-2 receptor) expression in response to antibody-mediated cross-linking of CD3 and CD28. Curcumin acted downstream of protein kinase C activation and intracellular Ca 2+ release to inhibit IκB phosphorylation, which is required for nuclear translocation of the transcription factor NFκB. In addition, IL-2-dependent DNA synthesis by mouse CTLL-2 cells, but not constitutive CD25 expression, was impaired in the presence of curcumin, which demonstrated an inhibitory effect on IL-2 receptor (IL-2R) signaling. IL-2-induced phosphorylation of STAT5A and JAK3, but not JAK1, was diminished in the presence of curcumin, indicating inhibition of critical proximal events in IL-2R signaling. In line with the inhibitory action of curcumin on IL-2R signaling, pretreatment of CD4 + CD25 + regulatory T-cells with curcumin downregulated suppressor function, as well as forkhead box p3 (Foxp3) expression. We conclude that curcumin inhibits IL-2 signaling by reducing available IL-2 and high affinity IL-2R, as well as interfering with IL-2R signaling.

Since April 1961, the 137 Cs and potassium content of the Chicago portion of the Tri-City Diet Sampling Program has been determined in bulk food samples by gamma-ray spectrometry using a 4'' x 4'' NaI (TI) crystal. Each variety of food (all fresh vegetables, all fresh fruit, etc.) is composited before measurement, and each sample is counted 400 to 1000 minutes. From these measurements composite daily and yearly food intakes are obtained. The results for the October 1978 semi-annual sampling are tabulated

Impact of Immunogenetic IL28B Polymorphism on Natural Outcome of HCV Infection

Valli De Re

2014-01-01

Full Text Available With the aim of investigating whether interleukin 28B gene (IL28B rs1297860 polymorphism is associated with different hepatitis C (HCV infection statuses, we compared IL28B allelic distribution in an Italian case series of 1050 patients with chronic infection and different outcomes, 47 individuals who spontaneously cleared HCV, and 178 blood donors. Furthermore, we compared IL28B variants among 3882 Caucasian patients with chronic infection, 397 with spontaneous clearance, and 1366 blood donors reported in PubMed. Overall data confirmed a relation between IL28B C allele and HCV spontaneous clearance. Furthermore, we found that IL28B T allele had a weak relation with chronic HCV progression to hepatocellular carcinoma. Study findings are in accordance with the hepatocellular carcinogenic model where IL28B TT genotype, by promoting a persistent chronic hepatitis which leads to both hepatocyte injury and chronic inflammation, could facilitate HCC development. Conversely, patients with lymphoproliferative disorders had not any significantly different IL28B rs1297860 allelic distribution than those with chronic HCV, but, like all chronic HCV-related diseases, they showed a lower CC frequency than patients who spontaneously cleared HCV. Study results confirmed the model of persistent HCV infection as a risk factor for the pathogenesis of both liver and lymphoproliferative disorders.

Structural Characterisation Reveals Mechanism of IL-13-Neutralising Monoclonal Antibody Tralokinumab as Inhibition of Binding to IL-13Rα1 and IL-13Rα2.

Interleukin (IL)-13 is a pleiotropic T helper type 2 cytokine frequently associated with asthma and atopic dermatitis. IL-13-mediated signalling is initiated by binding to IL-13Rα1, which then recruits IL-4Rα to form a heterodimeric receptor complex. IL-13 also binds to IL-13Rα2, considered as either a decoy or a key mediator of fibrosis. IL-13-neutralising antibodies act by preventing IL-13 binding to IL-13Rα1, IL-4Rα and/or IL-13Rα2. Tralokinumab (CAT-354) is an IL-13-neutralising human IgG4 monoclonal antibody that has shown clinical benefit in patients with asthma. To decipher how tralokinumab inhibits the effects of IL-13, we determined the structure of tralokinumab Fab in complex with human IL-13 to 2 Å resolution. The structure analysis reveals that tralokinumab prevents IL-13 from binding to both IL-13Rα1 and IL-13Rα2. This is supported by biochemical ligand-receptor interaction assay data. The tralokinumab epitope is mainly composed of residues in helices D and A of IL-13. It is mostly light chain complementarity-determining regions that are driving paratope interactions; the variable light complementarity-determining region 2 plays a key role by providing residue contacts for a network of hydrogen bonds and a salt bridge in the core of binding. The key residues within the paratope contributing to binding were identified as Asp50, Asp51, Ser30 and Lys31. This study demonstrates that tralokinumab prevents the IL-13 pharmacodynamic effect by binding to IL-13 helices A and D, thus preventing IL-13 from interacting with IL-13Rα1 and IL-13Rα2.

Independent replication of the findings from genome-wide association studies (GWAS) remains the gold standard for results validation. Our aim was to test the association of Behçet's disease (BD) with the interleukin-10 gene (IL10) and the IL-23 receptor-IL-12 receptor β2 (IL23R-IL12RB2) locus, each of which has been previously identified as a risk factor for BD in 2 different GWAS. Six haplotype-tagging single-nucleotide polymorphisms (SNPs) in IL10 and 42 in IL23R-IL12RB2 were genotyped in 973 Iranian patients with BD and 637 non-BD controls. Population stratification was assessed using a panel of 86 ancestry-informative markers. Subtle evidence of population stratification was found in our data set. In IL10, rs1518111 was nominally associated with BD before and after adjustment for population stratification (odds ratio [OR] for T allele 1.20, 95% confidence interval [95% CI] 1.02-1.40, unadjusted P [P(unadj) ] = 2.53 × 10(-2) ; adjusted P [P(adj) ] = 1.43 × 10(-2) ), and rs1554286 demonstrated a trend toward association (P(unadj) = 6.14 × 10(-2) ; P(adj) = 3.21 × 10(-2) ). Six SNPs in IL23R-IL12RB2 were found to be associated with BD after Bonferroni correction for multiple testing, the most significant of which were rs17375018 (OR for G allele 1.51, 95% CI 1.27-1.78, P(unadj) = 1.93 × 10(-6) ), rs7517847 (OR for T allele 1.48, 95% CI 1.26-1.74, P(unadj) = 1.23 × 10(-6) ), and rs924080 (OR for T allele 1.29, 95% CI 1.20-1.39, P = 1.78 × 10(-5) ). SNPs rs10489629, rs1343151, and rs1495965 were also significantly associated with BD in all tests performed. Results of meta-analyses of our data combined with data from other populations further confirmed the role of rs1518111, rs17375018, rs7517847, and rs924080 in the risk of BD, but no epistatic interactions between IL10 and IL23R-IL12RB2 were detected. Results of imputation analysis highlighted the importance of IL23R regulatory regions in the susceptibility to BD. These findings independently confirm

Objective: To study the clinical significance of changes of serum hs-CRP, IL-6, IL-10 and IL-18 levels in patients with acute conjunctivitis after treatment. Methods: Serum IL-6, IL-10 (with RIA) hs-CRP (with Immuno-turbidity) and IL-18 (with ELISA) levels were measured in 38 patients with acute conjunctivitis both before and after treatment as well as in 35 controls. Results: The serum hs-CRP, IL-6, IL-10 and IL-18 levels in the patients before treatment were significantly higher than those in the controls (P 0.05). Conclusion: Measurement of the changes of serum hs-CRP, IL-6, IL-10 and IL-18 levels after treatment might be inportant for outcome prediction in patients with acute conjunctivitis. (authors)

Idiopathic pulmonary fibrosis (IPF) is a progressive devastating, yet untreatable fibrotic disease of unknown origin. We investigated the contribution of the B-cell activating factor (BAFF), a TNF family member recently implicated in the regulation of pathogenic IL-17-producing cells in autoimmune diseases. The contribution of BAFF was assessed in a murine model of lung fibrosis induced by airway administered bleomycin. We show that murine BAFF levels were strongly increased in the bronchoalveolar space and lungs after bleomycin exposure. We identified Gr1(+) neutrophils as an important source of BAFF upon BLM-induced lung inflammation and fibrosis. Genetic ablation of BAFF or BAFF neutralization by a soluble receptor significantly attenuated pulmonary fibrosis and IL-1β levels. We further demonstrate that bleomycin-induced BAFF expression and lung fibrosis were IL-1β and IL-17A dependent. BAFF was required for rIL-17A-induced lung fibrosis and augmented IL-17A production by CD3(+) T cells from murine fibrotic lungs ex vivo. Finally we report elevated levels of BAFF in bronchoalveolar lavages from IPF patients. Our data therefore support a role for BAFF in the establishment of pulmonary fibrosis and a crosstalk between IL-1β, BAFF and IL-17A. Copyright © 2014 Elsevier Ltd. All rights reserved.

Full Text Available Leishmaniasis, resulting from infection with the protozoan parasite Leishmania, consists of a wide spectrum of clinical manifestations, from healing cutaneous lesions to fatal visceral infections. A particularly severe form of cutaneous leishmaniasis, termed mucosal leishmaniasis, exhibits decreased IL-10 levels and an exaggerated inflammatory response that perpetuates the disease. Using a mouse model of leishmaniasis, we investigated what cytokines contribute to increased pathology when IL-10-mediated regulation is absent. Leishmania major infected C57BL/6 mice lacking IL-10 regulation developed larger lesions than controls, but fewer parasites. Both IFN-γ and IL-17 levels were substantially elevated in mice lacking the capacity to respond to IL-10. IFN-γ promoted an increased infiltration of monocytes, while IL-17 contributed to an increase in neutrophils. Surprisingly, however, we found that IFN-γ did not contribute to increased pathology, but instead regulated the IL-17 response. Thus, blocking IFN-γ led to a significant increase in IL-17, neutrophils and disease. Similarly, the production of IL-17 by cells from leishmaniasis patients was also regulated by IL-10 and IFN-γ. Additional studies found that the IL-1 receptor was required for both the IL-17 response and increased pathology. Therefore, we propose that regulating IL-17, possibly by downregulating IL-1β, may be a useful approach for controlling immunopathology in leishmaniasis.

Interleukin-33 (IL-33): A nuclear cytokine from the IL-1 family.

Science.gov (United States)

Cayrol, Corinne; Girard, Jean-Philippe

2018-01-01

Interleukin-33 (IL-33) is a tissue-derived nuclear cytokine from the IL-1 family abundantly expressed in endothelial cells, epithelial cells and fibroblast-like cells, both during homeostasis and inflammation. It functions as an alarm signal (alarmin) released upon cell injury or tissue damage to alert immune cells expressing the ST2 receptor (IL-1RL1). The major targets of IL-33 in vivo are tissue-resident immune cells such as mast cells, group 2 innate lymphoid cells (ILC2s) and regulatory T cells (Tregs). Other cellular targets include T helper 2 (Th2) cells, eosinophils, basophils, dendritic cells, Th1 cells, CD8 + T cells, NK cells, iNKT cells, B cells, neutrophils and macrophages. IL-33 is thus emerging as a crucial immune modulator with pleiotropic activities in type-2, type-1 and regulatory immune responses, and important roles in allergic, fibrotic, infectious, and chronic inflammatory diseases. The critical function of IL-33/ST2 signaling in allergic inflammation is illustrated by the fact that IL33 and IL1RL1 are among the most highly replicated susceptibility loci for asthma. In this review, we highlight 15 years of discoveries on IL-33 protein, including its molecular characteristics, nuclear localization, bioactive forms, cellular sources, mechanisms of release and regulation by proteases. Importantly, we emphasize data that have been validated using IL-33-deficient cells. © 2017 The Authors. Immunological Reviews Published by John Wiley & Sons Ltd.

A Brief History of IL-1 and IL-1 Ra in Rheumatology

2017-05-01

Full Text Available The history of what, in 1979, was called interleukin-1 (IL-1, orchestrator of leukocyte inter-communication, began many years before then, initially by the observation of fever induction via the endogenous pyrogen (EP (1974 and then in rheumatology on the role in tissue destruction in rheumatoid diseases via the induction of collagenase and PGE2 in human synovial cells by a mononuclear cell factor (MCF (1977. Since then, the family has exploded to presently 11 members as well as many membrane-bound and soluble receptor forms. The discovery of a natural Interleukin-1 receptor antagonist (IL-1Ra in human biological fluids has highlighted the importance of IL-1 and IL-1Ra in human diseases. Evidence delineating its role in autoinflammatory syndromes and the elucidation of the macromolecular complex referred to as “inflammasome” have been instrumental to our understanding of the link with IL-1. At present, the IL-1blockade as therapeutic approach is crucial for many hereditary autoinflammatory diseases, as well as for adult-onset Still’s disease, crystal-induced arthropathies, certain skin diseases including neutrophil-triggered skin diseases, Behçet’s disease and deficiency of IL-1Ra and other rare fever syndromes. Its role is only marginally important in rheumatoid arthritis and is still under debate with regard to osteoarthritis, type 2 diabetes mellitus, cardiovascular diseases and cancer. This brief historical review focuses on some aspects of IL-1, mainly IL-1β and IL-Ra, in rheumatology. There are many excellent reviews focusing on the IL-1 family in general or with regard to specific diseases or biological discoveries.

Hepatitis B virus induces IL-23 production in antigen presenting cells and causes liver damage via the IL-23/IL-17 axis.

Directory of Open Access Journals (Sweden)

Full Text Available IL-23 regulates myriad processes in the innate and adaptive immune systems, and is a critical mediator of the proinflammatory effects exerted by Th17 cells in many diseases. In this study, we investigated whether and how hepatitis B virus (HBV causes liver damage directly through the IL-23 signaling pathway. In biopsied liver tissues from HBV-infected patients, expression of both IL-23 and IL-23R was remarkably elevated. In vivo observations also indicated that the main sources of IL-23 were myeloid dendritic cells (mDCs and macrophages. Analysis of in vitro differentiated immature DCs and macrophages isolated from healthy donors revealed that the HBV surface antigen (HBsAg efficiently induces IL-23 secretion in a mannose receptor (MR-dependent manner. Culture with an endosomal acidification inhibitor and the dynamin inhibitor showed that, upon binding to the MR, the HBsAg is taken up by mDCs and macrophages through an endocytosis mechanism. In contrast, although the HBV core antigen (HBcAg can also stimulate IL-23 secretion from mDCs, the process was MR- and endocytosis-independent. In addition, IL-23 was shown to be indispensible for HBsAg-stimulated differentiation of naïve CD4(+ T cells into Th17 cells, which were determined to be the primary source of IL-17 in HBV-infected livers. The cognate receptor, IL-17R, was found to exist on the hepatic stellate cells and mDCs, both of which might represent the potential target cells of IL-17 in hepatitis B disease. These data provide novel insights into a yet unrecognized mechanism of HBV-induced hepatitis, by which increases in IL-23 expression, through an MR/endocytosis-dependent or -independent manner, produce liver damage through the IL-23/IL-17 axis.

The IL-17F/IL-17RC Axis Promotes Respiratory Allergy in the Proximal Airways

Directory of Open Access Journals (Sweden)

2017-08-01

Full Text Available The interleukin 17 (IL-17 cytokine and receptor family is central to antimicrobial resistance and inflammation in the lung. Mice lacking IL-17A, IL-17F, or the IL-17RA subunit were compared with wild-type mice for susceptibility to airway inflammation in models of infection and allergy. Signaling through IL-17RA was required for efficient microbial clearance and prevention of allergy; in the absence of IL-17RA, signaling through IL-17RC on epithelial cells, predominantly by IL-17F, significantly exacerbated lower airway Aspergillus or Pseudomonas infection and allergic airway inflammation. In contrast, following infection with the upper respiratory pathogen Staphylococcus aureus, the IL-17F/IL-17RC axis mediated protection. Thus, IL-17A and IL-17F exert distinct biological effects during pulmonary infection; the IL-17F/IL-17RC signaling axis has the potential to significantly worsen pathogen-associated inflammation of the lower respiratory tract in particular, and should be investigated further as a therapeutic target for treating pathological inflammation in the lung.

Highlights: {yields} Curcumin inhibits CD4{sup +} T-lymphocyte proliferation. {yields} Curcumin inhibits interleukin-2 (IL-2) synthesis and CD25 expression by CD4{sup +} T-lymphocytes. {yields} Curcumin interferes with IL-2 receptor signaling by inhibiting JAK3 and STAT5 phosphorylation. {yields} IL-2-dependent regulatory T-lymphocyte function and Foxp3 expression is downregulated by curcumin. -- Abstract: Curcumin (diferulomethane) is the principal curcuminoid in the spice tumeric and a potent inhibitor of activation-induced T-lymphocyte proliferation; however, the molecular basis of this immunosuppressive effect has not been well studied. Here we show that micromolar concentrations of curcumin inhibited DNA synthesis by mouse CD4{sup +} T-lymphocytes, as well as interleukin-2 (IL-2) and CD25 ({alpha} chain of the high affinity IL-2 receptor) expression in response to antibody-mediated cross-linking of CD3 and CD28. Curcumin acted downstream of protein kinase C activation and intracellular Ca{sup 2+} release to inhibit I{kappa}B phosphorylation, which is required for nuclear translocation of the transcription factor NF{kappa}B. In addition, IL-2-dependent DNA synthesis by mouse CTLL-2 cells, but not constitutive CD25 expression, was impaired in the presence of curcumin, which demonstrated an inhibitory effect on IL-2 receptor (IL-2R) signaling. IL-2-induced phosphorylation of STAT5A and JAK3, but not JAK1, was diminished in the presence of curcumin, indicating inhibition of critical proximal events in IL-2R signaling. In line with the inhibitory action of curcumin on IL-2R signaling, pretreatment of CD4{sup +}CD25{sup +} regulatory T-cells with curcumin downregulated suppressor function, as well as forkhead box p3 (Foxp3) expression. We conclude that curcumin inhibits IL-2 signaling by reducing available IL-2 and high affinity IL-2R, as well as interfering with IL-2R signaling.

FANCA and FANCC modulate TLR and p38 MAPK–dependent expression of IL-1β in macrophages

Hematopoietic stem and progenitor cells with inactivated Fanconi anemia (FA) genes, FANCA and FANCC, are hypersensitive to inflammatory cytokines. One of these, tumor necrosis factor α (TNF-α), is also overproduced by FA mononuclear phagocytes in response to certain Toll-like receptor (TLR) agonists, creating an autoinhibitory loop that may contribute to the pathogenesis of progressive bone marrow (BM) failure and selection of TNF-α–resistant leukemic stem cell clones. In macrophages, the TNF-α overproduction phenotype depends on p38 mitogen-activated protein kinase (MAPK), an enzyme also known to induce expression of other inflammatory cytokines, including interleukin 1β (IL-1β). Reasoning that IL-1β might be involved in a like autoinhibitory loop, we determined that (1) TLR activation of FANCA- and FANCC-deficient macrophages induced overproduction of both TNF-α and IL-1β in a p38-dependent manner; (2) exposure of Fancc-deficient BM progenitors to IL-1β potently suppressed the expansion of multipotent progenitor cells in vitro; and (3) although TNF-α overexpression in FA cells is controlled posttranscriptionally by the p38 substrate MAPKAPK-2, p38-dependent overproduction of IL-1β is controlled transcriptionally. We suggest that multiple inflammatory cytokines overproduced by FANCA- and FANCC-deficient mononuclear phagocytes may contribute to the progressive BM failure that characterizes FA, and that to achieve suppression of this proinflammatory state, p38 is a more promising molecular therapeutic target than either IL-1β or TNF-α alone.

Inflammatory damage of mucosal surface of the eye is a hallmark of dry eye disease (DED), and in severe cases can lead to significant discomfort, visual impairment, and blindness. DED is a multifactorial autoimmune disorder with a largely unknown pathogenesis. Using a cross-sectional patient study and a well-characterized murine model of DED, herein we investigated the immunoregulatory function of interleukin-22 (IL-22) in the pathogenesis of DED. We found that IL-22 levels were elevated in lacrimal fluids of DED patients and inversely correlated with severity of disease. Acinar cells of the lacrimal glands, not inflammatory immune cells, are the primary source of IL-22, which suppresses inflammation in ocular surface epithelial cells upon desiccating stress. Moreover, loss of function analyses using IL-22 knock-out mice demonstrated that IL-22 is essential for suppression of ocular surface infiltration of Th17 cells and inhibition of DED induction. Our novel findings elucidate immunoregulatory function of lacrimal gland-derived IL-22 in inhibiting IL-17-mediated ocular surface epitheliopathy in DED thus making IL-22 a new relevant therapeutic target.

The United States reports the highest levels of firearm homicide incidences compared to other high income countries, and the focus and causes of these incidences within the US differ by demographic characteristics and location such as urban versus rural environment. Despite these findings, few studies have published on rates varied by region within a city. This study aims to provide descriptive analysis of the rates of firearm homicide by age, sex, and race/ethnicity in each of the seven City of Chicago regions, and to determine if the rates of firearm homicide differ by demographics among the seven City of Chicago regions. The Illinois Violent Death Reporting System conducts routine surveillance of violent deaths. Decedents were selected according to the following criteria: manner of death was homicide, weapon type was firearm, and location of injury that led to death was the City of Chicago. Location of injury was broken down by regions: North, Northwest, Center, West, South, Southwest, and Far South. Multiyear rates per 100,000 and corresponding 95% confidence intervals were calculated. There were 2,254 victims of homicide by firearm in the City of Chicago. The overall rate across Chicago for all demographics was 12.9 (12.1-13.5 per 100,000) with an average age of 27.4. The highest age group (20-24) for firearm homicide rates was 43.2 (39.7-46.7) per 100,000. For the youngest age group (10-14), only the Southwest (3.3-10.4) region reported any firearm incidence. The 20 to 24 age group reported the highest rates of all age groups within the South (107.9-151.7), West (80.3-108.2), and Far South (69.6-105.3) regions, whereas the North and Northwest reported the lowest rates for all regions by age. Black firearm homicide rates were 33.5 (31.9-35.1) per 100,000 versus Hispanic and non-Hispanic white firearm homicide rates of 8.5 (7.7-9.3) and 1.2 (1-1.5) per 100,000, respectively. Lastly, the West reported the highest firearm rates at 29.1 (657). In conclusion

Neutrophil granule proteases are thought to function as anti-microbial effectors, cooperatively hydrolyzing microorganisms within phagosomes, or upon deployment into the extracellular space. However, evidence also suggests that neutrophil proteases play an important role in the coordination and escalation of inflammatory reactions, but how this is achieved has been obscure. IL-1 family cytokines are important initiators of inflammation and are typically released via necrosis but require proteolytic processing for activation. Here, we show that proteases liberated from activated neutrophils can positively or negatively regulate the activity of six IL-1 family cytokines (IL-1α, IL-1β, IL-33, IL-36α, IL-36β, and IL-36γ) with exquisite sensitivity. In contrast, extracellular neutrophil proteases displayed very poor bactericidal activity, exhibiting 100-fold greater potency toward cytokine processing than bacterial killing. Thus, in addition to their classical role as phagocytes, neutrophils play an important immunoregulatory role through deployment of their granule proteases into the extracellular space to process multiple IL-1 family cytokines.

The role of CD40L, IL-10 and IL-17 in radioprotection

International Nuclear Information System (INIS)

Li Ting

2003-01-01

CD40L/CD40 interaction is central to the control of thymus-dependent humoral immunity and cell mediated immune responses. IL-17 has been shown to induce the production of IL-6 and G-CSF, which can induce proliferation and differentiation of CD34 + hematopoietic progenitors. IL-10 can interfere with up-regulation of costimulatory molecules, thus suppressing the production of costimulatory cytokines, such as IL-12. IL-10 has been implicated as an essential mediator in the induction of systemic immune suppression following ultraviolet (UV) exposure. Treating UV-irradiated mice with anti-IL-10 blocks the induction of immune suppression

An interferon signature is involved in the pathogenesis of primary Sjögren syndrome (pSS), but whether the signature is type 1 or type 2 remains controversial. Mouse models and genetic studies suggest the involvement of T H 1 and type 2 interferon pathways. Likewise, polymorphisms of the IL-12A gene (IL12A), which encodes for IL-12p35, have been associated with pSS. The IL-12p35 subunit is shared by 2 heterodimers: IL-12 and IL-35. We sought to confirm genetic association of the IL12A polymorphism and pSS and elucidate involvement of the IL-12/IL-35 balance in patients with pSS by using functional studies. The genetic study involved 673 patients with pSS from 2 French pSS cohorts and 585 healthy French control subjects. Functional studies were performed on sorted monocytes, irrespective of whether they were stimulated. IL12A mRNA expression and IL-12 and IL-35 protein levels were assessed by using quantitative RT-PCR and ELISA and a multiplex kit for IL-35 and IL-12, respectively. We confirmed association of the IL12A rs485497 polymorphism and pSS and found an increased serum protein level of IL-12p70 in patients with pSS carrying the risk allele (P = .016). Serum levels of IL-12p70 were greater in patients than control subjects (P = .0001), especially in patients with more active disease (P = .05); conversely, IL-35 levels were decreased in patients (P = .0001), especially in patients with more active disease (P = .05). In blood cellular subsets both IL12p35 and EBV-induced gene protein 3 (EBI3) mRNAs were detected only in B cells, with a trend toward a lower level among patients with pSS. Our findings emphasize involvement of the IL-12/IL-35 balance in the pathogenesis of pSS. Serum IL-35 levels were associated with low disease activity, in contrast with serum IL-12p70 levels, which were associated with more active disease.

Decreased IL-33 Production Contributes to Trophoblast Cell Dysfunction in Pregnancies with Preeclampsia

Directory of Open Access Journals (Sweden)

2018-01-01

Full Text Available Preeclampsia (PE is a life-threatening pregnancy complication which is related to aggradation of risk regarding fetal and maternal morbidity and mortality. Dysregulation of systemic inflammatory response and dysfunction of trophoblast cells have been proposed to be involved in the development and progression of PE. Some studies have demonstrated that interleukin-33 (IL-33 is an immunomodulatory cytokine that is associated with the immune regulation of tumor cells. However, little is known whether IL-33 and its receptor ST2/IL-1 R4 could regulate trophoblast cells, which are associated with the pathogenesis of PE. In this study, our target is to explore the impact of IL-33 on trophoblast cells and elucidate its underlying pathophysiological mechanisms. Placental tissues from the severe PE group (n=11 and the normotensive pregnant women’s group (n=11 were collected for the protein expression and distribution of IL-33 along with its receptor ST2/IL-1 R4 via Western blot analysis and immunohistochemistry, respectively. We discovered that the level of IL-33 was decreased in placental tissues of pregnant women with PE, while no distinction was observed in the expression of ST2/IL-1 R4. These results were further verified in villous explants which were treated with sodium nitroprusside with different concentrations, to simulate the pathological environment of PE. To investigate IL-33 effects on trophoblast cells separately, IL-33 shRNA was introduced into HTR8/SVneo cells and villi. IL-33 shRNA weakened the proliferation, migration, and invasion capacity of HTR8/SVneo cells. The migration distance of villous explants was also markedly decreased. The reduced invasion of trophoblast cells is a result of IL-33 knockdown which could be related to the decline of MMP2/9 activity and the increased utterance of TIMP1/2. Overall, our findings demonstrated that the reduction of IL-33 production was connected with the reduced functional capability of

Th17 cells play a major role in coordinating the host defence in oropharyngeal candidiasis. In this study we investigated the involvement of the Th17 response in an animal model of vulvovaginal candidiasis (VVC). To monitor the course of infection we exploited a new in vivo imaging technique. i) The progression of VVC leads to a strong influx of neutrophils in the vagina soon after the challenge which persisted despite the resolution of infection; ii) IL-17, produced by vaginal cells, particularly CD4 T cells, was detected in the vaginal wash during the infection, reaching a maximum 14 days after the challenge; iii) The amount and kinetics of IL-23 in vaginal fluids were comparable to those in vaginal cells; iv) The inhibition of Th17 differentiation led to significant inhibition of IL-17 production with consequent exacerbation of infection; v) An increased production of βdefensin 2 was manifested in cells of infected mice. This production was strongly reduced when Th17 differentiation was inhibited and was increased by rIL-17 treatment. These results imply that IL-17 and Th17, along with innate antimicrobial factors, have a role in the immune response to vaginal candidiasis.

Full Text Available BACKGROUND/OBJECTIVE: Osteopontin (OPN and IL-18 are known inflammatory mediators and both participate in a wide range of biological processes linked to immunological disorders. Since an interaction between OPN and IL-18 has not been studied in obesity, we investigated whether: (i their levels were simultaneously elevated in obese individuals; (ii OPN was associated with IL-18 in obese individuals and (iii their levels associated with fasting blood glucose (FBG and BMI. SUBJECTS AND METHODS: PBMCs and plasma samples were isolated from 60 individuals including lean as well as overweight and obese individuals. Subcutaneous adipose tissue samples were obtained. OPN and IL-18 were measured by ELISA. OPN and IL-18 mRNA expression was quantified by real time quantitative RT-PCR. RESULTS: Obese individuals exhibited significantly increased circulating OPN levels as compared with lean individuals (obese 2865±101; lean 1681±116 pg/ml; P<0.0001. IL-18 levels were also high in obese individuals (obese 491±39, lean 301±26 pg/ml; P = 0.0009. OPN and IL-18 expression were simultaneously up-regulated (OPN: 5.4-Fold; IL-18: 8.9-Fold; P<0.05 in PBMCs from obese individuals compared to lean group. Adipose tissue from obese individuals had high expression of OPN (7.3-Fold and IL-18 (9.6-Fold. Plasma OPN levels correlated positively with FBG levels (r = 0.32, P = 0.02. Similarly, IL-18 correlated positively with FBG levels (r = 0.406, P = 0.0042. Stepwise multiple regression analysis showed an independent association of BMI with OPN and IL-18. Interestingly, OPN levels increased progressively with an increase in IL-18 levels (r = 0.52, P = 0.0004. We also examined the regulatory role of IL-18 in OPN secretion from PBMCs. Neutralizing anti-IL-18Rα mAb reduced OPN secretion. CONCLUSION: These findings represent the first observation that plasma, PBMC and adipose tissue OPN and IL-18 are simultaneously increased and correlate with each

Cytokine assays are gaining increasing importance for human immune monitoring because they reliably detect antigen-specific T cells in primary PBMC, even at low clonal sizes. Double color ELISPOT assays permit the simultaneous visualization of cells producing two different cytokines. Permitting the simultaneous assessment of type 1 and 2 immunity and due to the limited numbers of PBMC available from human study subjects, double color assays should be particularly attractive for clinical trials. Since the performance of double color assays has not yet been validated, we set out to compare them to single color measurements. Testing the recall antigen-induced cytokine response of PBMC, we found that double color assays regularly provided lower numbers of IFN-gamma and IL-5 spots than single color measurements when IL-2 detection was part of the double color assay. We showed that the inhibitory effect resulted from IL-2 absorption and could be overcome by either antibody free preactivation cultures or by inclusion of anti-CD28 antibody. In contrast, the simultaneous detection of IL-2 did not affect the numbers of IL-4 spots. Therefore, unlike IL-2/IL-4 and IFN-gamma/IL-5 assays, IL-2/IFN-gamma, and IL-2/IL-5 assays require compensation for the IL-2 capture to provide accurate numbers for the frequencies of cytokine producing memory T cells.

Objective: To explore the influence of high semen plasma contents of the cytokines (IL-2, IL-6, IL-8, TNF-α) on male fertility. Methods: Semen plasma levels of IL-2, IL-6, IL-8, and TNF-α were determined with RIA in 126 infertile and 20 fertile males. Results: Semen plasma contents of the 4 cytokines in infertile subjects were significantly higher than those in fertile ones (p 4/HP, n=15) had significantly higher contents of cytokines than those without leucocytospermia (WBC<4/HP, n=111). Besides, TNF-α contents in subjects with lower sperm activity and less motility rate as well as IL-8 contents in subjects with less sperm motility rate were both significantly higher than those in subjects with more normal sperms (p<0.01, p<0.05). Conclusion: High semen plasma cytokines contents represent existing local infection and enhanced auto-immune status, both damaging to sperms. Infertility would be the inevitable consequence. Monitoring of changes of the cytokine contents should be a part of fertility studies

Becoming a uCity: The Case of Chicago

Directory of Open Access Journals (Sweden)

Zorica Nedovic-Budic

Full Text Available ABSTRACT: The concept of a ubiquitous city, or uCity, is gaining attention worldwide. In a uCity, anyone is enabled by information and communication technologies (ICT to do anything, anywhere, at any time. The uCity concept has spread more quickly than its implementation, which relies on a complex set of interrelated technologies, practices, and actors, including but not limited to the provision of ICT infrastructure, the availability and accessibility of information and services, and the adoption of mobile communication devices by a variety of users. To aid in measuring and implementing a uCity, we explore ways to measure the “ubiquity” of a city, with particular attention given to the first “A” above – i.e., “anyone”. Empirical findings from Chicago highlight: 1 ICT access, 2 the connectivity of institutions and individuals, and 3 the ubiquity of virtuality. A socio-technical perspective and social network and social capital theories guide this study. The underlying social and motivational processes are essential to all aspects of becoming a uCity.

Genetic deficiency in the expression of interleukin-10 (IL-10) is associated with the onset and progression of experimental inflammatory bowel disease (IBD). The clinical significance of IL-10 expression is supported by studies showing that immune-augmentation of IL-10 prevents inflammation and mucosal damage in animal models of colitis and in human colitis. Interleukin-10 (IL-10), an endogenous anti-inflammatory and immunomodulating cytokine, has been shown to prevent some inflammation and injury in animal and clinical studies, but the efficacy of IL-10 treatment remains unsatisfactory. We found that intra-peritoneal administration of adenoviral IL-10 to mice significantly reversed colitis induced by administration of 3% DSS (dextran sulfate), a common model of colitis. Adenoviral IL-10 (Ad-IL10) transfected mice developed high levels of IL-10 (394 +/- 136 pg/ml) within the peritoneal cavity where the adenovirus was expressed. Importantly, when given on day 4 (after the induction of colitis w/DSS), Ad-IL10 significantly reduced disease activity and weight loss and completely prevented histopathologic injury to the colon at day 10. Mechanistically, compared to Ad-null and DSS treated mice, Ad-IL10 and DSS-treated mice were able to suppress the expression of MAdCAM-1, an endothelial adhesion molecule associated with IBD. Our results suggest that Ad-IL10 (adenoviral IL-10) gene therapy of the intestine or peritoneum may be useful in the clinical treatment of IBD, since we demonstrated that this vector can reverse the course of an existing gut inflammation and markers of inflammation.

The pathogenesis of spondyloarthritis (SpA) involves activation of the innate immune system, inflammation and new bone formation. The two cytokines interleukin (IL)-20 and IL-24 have been shown to link innate immune activation and tissue homeostasis. We hypothesized that these two cytokines...... are secreted as part of activation of the innate immune system and affect bone homeostasis in SpA. IL-20 and IL-24 were measured in plasma from axial SpA patients (n = 83). Peripheral SpA patients (n = 16) were included for in-vitro cell culture studies. The plasma IL-20 and IL-24 levels were increased in Sp...

This study examined the changes of serum levels of interleukin (IL)-16, IL-18 and immunoglobulins and the correlation of serum IL-16, IL-18 levels and immunoglobulins in children with asthma and aimed to explore the role of IL-16, IL-18 and immunoglobulins in the pathogenesis of asthma. Thirty-four children with asthma and 21 age and gender-matched healthy children were enrolled in this study. The levels of IL-16, IL-18 and immunoglobulin E (IgE) were determined using ELISA. Immunoglobulin G (IgG), immunoglobulin M (IgM) and immunoglobulin A (IgA) were detected by immunoturbidimetry. The levels of IL-16, IL-18 and IgE in patients with asthma at both acute attack and convalescence stages were significantly higher than those in healthy controls. An increased IgG and a decreased IgA levels were found in asthmatic patients at the acute attack stage. There was a positive correlation between the IL-16 and IL-18 levels at both acute attack and convalescence stages of asthma (r=0.70, P attack stage of asthma (r=0.624, P asthma. The immunologic imbalance exists in children with asthma at both acute attack and convalescence stages. Anti-allergic therapy should be administered through the acute attack to the convalescence stages of asthma.

Silica exposure can cause lung inflammation and fibrosis, known as silicosis. Interleukin-17A (IL-17A) and Th17 cells play a pivotal role in controlling inflammatory diseases. However, the roles of IL-17A and Th17 cells in the progress of silica-induced inflammation and fibrosis are poorly understood. This study explored the effects of IL-17A on silica-induced inflammation and fibrosis. We used an anti-mouse IL-17A antibody to establish an IL-17A-neutralized mice model, and mice were exposed to silica to establish an experimental silicosis model. We showed that IL-17A neutralization delayed neutrophil accumulation and progression of silica-induced lung inflammation and fibrosis. IL-17A neutralization reduced the percentage of Th17 in CD4 + T cells, decreased IL-6 and IL-1β expression, and increased Tregs at an early phase of silica-induced inflammation. Neutralization of IL-17A delayed silica-induced Th1/Th2 immune and autoimmune responses. These results suggest that IL-17A neutralization alleviates early stage silica-induced lung inflammation and delays progression of silica-induced lung inflammation and fibrosis. Neutralization of IL-17A suppressed Th17 cell development by decreasing IL-6 and/or IL-1β and increased Tregs at an early phase of silica-induced inflammation. Neutralization of IL-17A also delayed the Th1/Th2 immune response during silica-induced lung inflammation and fibrosis. IL-17A may play a pivotal role in the early phase of silica-induced inflammation and may mediate the Th immune response to influence silica-induced lung inflammation and fibrosis in mice. - Highlights: • Neutralization of IL-17A alleviated silica-induced lung inflammation of early stage. • Neutralization of IL-17A decreased Th17 cells and increased Tregs. • IL-17A mediated the reciprocal relationship of Th17/Tregs by IL-6 and/or IL-1β. • Neutralization of IL-17A delayed silica-induced Th1/Th2 immune response. • Neutralization of IL-17A delayed silica-induced lung

Full Text Available Kavitha R Sivaraman, Chirag G Patel, Thasarat S Vajaranant, Ahmad A ArefDepartment of Ophthalmology and Visual Sciences, Illinois Eye and Ear Infirmary, University of Illinois at Chicago School of Medicine, Chicago, IL, USAAbstract: Primary pigment dispersion syndrome (PPDS is a bilateral condition that occurs in anatomically predisposed individuals. PPDS may evolve into pigmentary glaucoma, but it is difficult to predict which patients will progress. Secondary pigment dispersion is more often unilateral and acquired as a result of surgery, trauma, or intraocular tumor, but can likewise lead to pigmentary glaucoma. We report two cases of patients with bilateral PPDS who developed secondary pigment dispersion and pigmentary glaucoma in one eye. Patients with PPDS who acquire a secondary mechanism of pigment dispersion may be at an increased risk of progression to pigmentary glaucoma, presumably due to an increased burden of liberated pigment. In addition to regular surveillance for progression to glaucoma from PPDS, secondary causes of pigmentary dispersion in these eyes should be considered when patients present with grossly asymmetric findings. When secondary pigment dispersion is identified in eyes with PPDS, we recommend prompt intervention to alleviate the cause of secondary pigment dispersion and/or aggressive control of intraocular pressure to limit glaucomatous damage.Keywords: primary pigment dispersion syndrome, pigmentary glaucoma

Commensal bacteria and MAMPs are necessary for stress-induced increases in IL-1β and IL-18 but not IL-6, IL-10 or MCP-1.

Directory of Open Access Journals (Sweden)

Thomas Maslanik

Full Text Available Regular interactions between commensal bacteria and the enteric mucosal immune environment are necessary for normal immunity. Alterations of the commensal bacterial communities or mucosal barrier can disrupt immune function. Chronic stress interferes with bacterial community structure (specifically, α-diversity and the integrity of the intestinal barrier. These interferences can contribute to chronic stress-induced increases in systemic IL-6 and TNF-α. Chronic stress, however, produces many physiological changes that could indirectly influence immune activity. In addition to IL-6 and TNF-α, exposure to acute stressors upregulates a plethora of inflammatory proteins, each having unique synthesis and release mechanisms. We therefore tested the hypothesis that acute stress-induced inflammatory protein responses are dependent on the commensal bacteria, and more specifically, lipopolysaccharide (LPS shed from Gram-negative intestinal commensal bacteria. We present evidence that both reducing commensal bacteria using antibiotics and neutralizing LPS using endotoxin inhibitor (EI attenuates increases in some (inflammasome dependent, IL-1 and IL-18, but not all (inflammasome independent, IL-6, IL-10, and MCP-1 inflammatory proteins in the blood of male F344 rats exposed to an acute tail shock stressor. Acute stress did not impact α- or β- diversity measured using 16S rRNA diversity analyses, but selectively reduced the relative abundance of Prevotella. These findings indicate that commensal bacteria contribute to acute stress-induced inflammatory protein responses, and support the presence of LPS-mediated signaling in stress-evoked cytokine and chemokine production. The selectivity of the commensal bacteria in stress-evoked IL-1β and IL-18 responses may implicate the inflammasome in this response.

The inflammatory response in infectious and autoimmune diseases is regulated by the balance between pro- and anti-inflammatory cytokines. The IL-1 complex contains polymorphic genes coding for IL-1alpha, IL-1beta and IL-1Ra. The IL-1Ra (variable number of tanden repeat) VNTR polymorphism has been shown to influence the capacity to produce IL-1beta and IL-1Ra after in vitro stimulation. Allele 2 of this polymorphism is associated with a number of inflammatory diseases. To determine the impact of the IL-1Ra polymorphism on in vivo human cytokine synthesis, we used a yellow fever vaccination model for the induction of cytokine synthesis in healthy volunteers. Two different yellow fever vaccines were used. After administration of the RKI vaccine (34 volunteers), plasma TNF-alpha concentration increased from 13.4 +/- 0.9 pg/ml to 23.3 +/- 1.1 pg/ml (P < 0.001), and plasma IL-1Ra concentration increased from 308 +/- 25 pg/ml to 1019 +/- 111 pg/ml (P < 0.001), on day 2. Using Stamaril vaccine, no increase in the plasma concentrations of either TNF-alpha or IL-1Ra could be detected (n = 17). Only the RKI vaccine induced TNF-alpha synthesis after in vitro stimulation of MNC. Carriers of allele 2 of the IL-1Ra polymorphism had increased baseline concentrations of IL-1Ra (350 +/- 32 pg/ml) compared with non-carriers (222 +/- 18 pg/ml, P < 0.001), and decreased concentrations of IL-1beta (0.9 +/- 0.2 pg/ml for carriers versus 2.8 +/- 0.7 pg/ml for non-carriers, P = 0.017). After yellow fever vaccination (RKI vaccine), no significant differences in the increase of IL-1Ra plasma levels were detected between carriers and non-carriers of allele 2 of the IL-1Ra gene polymorphism. This is the first study to examine the influence of this genetic polymorphism on in vivo-induced human IL-1beta and IL-1Ra synthesis. Baseline concentrations of IL-1Ra and IL-1beta were significantly influenced by the IL-1Ra polymorphism. No influence of the IL-1Ra polymorphism on the in vivo

Full Text Available Si riconosce che il workshop costituisce un modello dinamico di apprendimento, in continua evoluzione e sperimentazione, e in grado di essere costantemente riformulato per giungere a nuove e stimolanti situazioni per insegnare la pratica dell'architettura. Si tratta infatti di un modello particolarmente adatto alla ricerca di un approccio globale e coerente al progetto architettonico, dato che evita di separare gli argomenti in frammenti isolati nel processo progettuale. Riunire i gruppi di lavoro nello stesso spazio e nel tempo limitato a disposizione richiede un pensiero intenso e un ritmo di produzione che aiuta a migliorare il rapporto tra i riferimenti teorici riportabili al soggetto trattato e gli aspetti relativi all'elaborazione e alla comunicazione del progetto architettonico. / We recognize the workshop as a dynamic model of learning, which is continuously changing and experimenting, and is able to be constantly redesigned to achieve new and stimulating situations for teaching the practice of architecture. In fact it is a particularly suitable model for seeking a global and coherent approach to the architectural project, while avoiding separating the topics into isolated fragments, throughout the project’s process. Bringing work teams together in the same space and within a reduced time limit requires intensive thought and a rhythm of production which helps improve the relation between the theoretical references of the subject’s production and the aspects related to producing work and communication elements for the architectural project.

Interleukin (IL)-induced inflammatory responses are critical for the pathogenesis of Helicobacter pylori (H. pylori)-induced gastritis. IL-33 represents a recently discovered proinflammatory cytokine involved in inflammatory diseases, but its relevance to H. pylori-induced gastritis is unknown. Here, we found that gastric IL-33 mRNA and protein expression were elevated in gastric mucosa of both patients and mice infected with H. pylori, which is positively correlated with bacterial load and the degree of gastritis. IL-33 production was promoted via extracellular regulated protein kinases (ERK) signaling pathway activation by gastric epithelial cells in a cagA-dependent manner during H. pylori infection, and resulted in increased inflammation and bacteria burden within the gastric mucosa. Gastric epithelial cell-derived IL-33 promoted TNF-α production from mast cells in vitro, and IL-33 increased TNF-α production in vivo. Increased TNF-α inhibited gastric epithelial cell proliferation, conducing to the progress of H. pylori-associated gastritis and bacteria colonization. This study defined a patent regulatory networks involving H. pylori, gastric epithelial cell, IL-33, mast cell, and TNF-α, which jointly play a pathological effect within the gastric circumstances. It may be a valuable strategy to restrain this IL-33-dependent pathway in the treatment of H. pylori-associated gastritis.

IL-15 deficient tax mice reveal a role for IL-1α in tumor immunity.

Directory of Open Access Journals (Sweden)

Daniel A Rauch

Full Text Available IL-15 is recognized as a promising candidate for tumor immunotherapy and has been described as both a promoter of cancer and a promoter of anti-cancer immunity. IL-15 was discovered in cells transformed by HTLV-1, the etiologic agent of adult T cell leukemia/lymphoma (ATL and the human retrovirus that carries the Tax oncogene. We have developed the TAX-LUC mouse model of ATL in which Tax expression drives both malignant transformation and luciferase expression, enabling non-invasive imaging of tumorigenesis in real time. To identify the role of IL-15 in spontaneous development of lymphoma in vivo, an IL-15(-/- TAX-LUC strain was developed and examined. The absence of IL-15 resulted in aggressive tumor growth and accelerated mortality and demonstrated that IL-15 was not required for Tax-mediated lymphoma but was essential for anti-tumor immunity. Further analysis revealed a unique transcriptional profile in tumor cells that arise in the absence of IL-15 that included a significant increase in the expression of IL-1α and IL-1α-regulated cytokines. Moreover, anti-IL-1α antibodies and an IL-1 receptor antagonist (Anakinra were used to interrogate the potential of IL-1α targeted therapies in this model. Taken together, these findings identify IL-15 and IL-1α as therapeutic targets in lymphoma.

Pro-inflammatory signaling by IL-10 and IL-22: bad habit stirred up by interferons ?

Directory of Open Access Journals (Sweden)

Heiko eMühl

2013-02-01

Full Text Available Interleukin (IL-10 and IL-22 are key members of the IL-10 cytokine family that share characteristic properties such as defined structural features, usage of IL-10R2 as one receptor chain, and activation of signal transducer and activator of transcription (STAT-3 as dominant signaling mode. IL-10, formerly known as cytokine synthesis inhibitory factor, is key to deactivation of monocytes/macrophages and dendritic cells. Accordingly, pre-clinical studies document its anti-inflammatory capacity. However, the outcome of clinical trials assessing the therapeutic potential of IL-10 in prototypic inflammatory disorders has been disappointing. In contrast to IL-10, IL-22 acts primarily on non-leukocytic cells, in particular epithelial cells of intestine, skin, liver, and lung. STAT3-driven proliferation, anti-apoptosis, and anti-microbial tissue protection is regarded a principal function of IL-22 at host/environment interfaces. In this hypothesis article, hidden/underappreciated pro-inflammatory characteristics of IL-10 and IL-22 are outlined and related to cellular priming by type I interferon. It is tempting to speculate that an inherent inflammatory potential of IL-10 and IL-22 confines their usage in tissue protective therapy and beyond that determines in some patients efficacy of type I interferon treatment.

Corneal infections are frequent and potentially vision-threatening diseases, and despite the significance of the immunological response in animal models of microbial keratitis (MK), it remains unclear in humans. The aim of this study was to describe the cytokine profile of tears in patients with MK. Characteristics of ocular lesions such as size of the epithelial defect, stromal infiltration, and hypopyon were analyzed. Immunological evaluation included determination of interleukine (IL)-1β, IL-6, IL-8, IL-10, IL-12 and tumor necrosis factor (TNF)-α in tear samples obtained from infected eyes of 28 patients with MK and compared with their contralateral non-infected eyes. Additionally, frequency of CD4+, CD8+, CD19+ and CD3−CD56+ cells was also determined in peripheral blood mononuclear cells in patients with MK, and compared with 48 healthy controls. Non-significant differences were observed in the size of the epithelial defect, stromal infiltration, and hypopyon. Nevertheless, we found an immunological profile apparently related to MK etiology. IL-8 > IL-6 in patients with bacterial keratitis; IL-8 > IL-6 > IL-1β and increased frequency of circulating CD3−CD56+ NK cells in patients with gram-negative keratitis; and IL-8 = IL-6 > IL-1β in patients with fungal keratitis. Characterization of tear cytokines from patients with MK could aid our understanding of the immune pathophysiological mechanisms underlying corneal damage in humans. PMID:25741769

Oral tolerance is a key feature of intestinal immunity, generating systemic tolerance to ingested antigens (Ag). Dendritic cells (DC) have been revealed as important immune regulators, however, the precise role of DC in oral tolerance induction remains unclear. We investigated the characteristics of DC in spleen, mesenteric lymph node (MLN), and Peyer's patch (PP) after oral Ag administration in a TCR-transgenic mouse model. DC from PP and MLN of tolerized mice induced IL-10 production but not Foxp3 expression in cocultured T cells. IL-10 production was markedly increased after 5-7-day Ag administration especially in PP DC. On the other hand, IL-27 production was increased after 2-5-day Ag administration. CD11b(+) DC, which increased after ingestion of Ag, prominently expressed IL-10 and IL-27 compared with CD11b(-) DC. These results suggest that IL-10 and IL-27 producing DC are increased by interaction with antigen specific T cells in PP, and these DC act as an inducer of IL-10 producing T cells in oral tolerance.

IL-7 Induces an Epitope Masking of γc Protein in IL-7 Receptor Signaling Complex

Full Text Available IL-7 signaling via IL-7Rα and common γ-chain (γc is necessary for the development and homeostasis of T cells. Although the delicate mechanism in which IL-7Rα downregulation allows the homeostasis of T cell with limited IL-7 has been well known, the exact mechanism behind the interaction between IL-7Rα and γc in the absence or presence of IL-7 remains unclear. Additionally, we are still uncertain as to how only IL-7Rα is separately downregulated by the binding of IL-7 from the IL-7Rα/γc complex. We demonstrate here that 4G3, TUGm2, and 3E12 epitope masking of γc protein are induced in the presence of IL-7, indicating that the epitope alteration is induced by IL-7 binding to the preassembled receptor core. Moreover, the epitope masking of γc protein is inversely correlated with the expression of IL-7Rα upon IL-7 binding, implying that the structural alteration of γc might be involved in the regulation of IL-7Rα expression. The conformational change in γc upon IL-7 binding may contribute not only to forming the functional IL-7 signaling complex but also to optimally regulating the expression of IL-7Rα.

Interleukin-21 (IL-21) enhances the survival and cytotoxic properties of cytotoxic T cells (CTLs) and exhibits essential roles in controlling chronic viral infections. HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) is a chronic progressive inflammatory disease of the nervous system. The main determinant of disease progression is efficiency of the CTL response to Human T lymphotropic virus types I (HTLV-1). In this study, the expression of host IL-21 and HTLV-I Tax and proviral load (PVL) was evaluated to understand the role and mechanism of IL-21 in HTLV-1 infections and the subsequent development of HAM/TSP. A cross-sectional study was carried out on 20 HAM/TSP patients, 20 asymptomatic HTLV-1 carriers (ACs) and 20 healthy controls (HCs) to evaluate the expression of IL-21 and Tax and PVL in non-activated and phorbol myristate acetate (PMA)-ionomycin-activated peripheral blood mononuclear cells (PBMCs). The mean mRNA expression of IL-21 in the non-activated and activated PBMCs was higher (by 5-13 times) in the HAM/TSP patients than in ACs and HCs (p Tax and PVL was observed in the HAM/TSP subjects than ACs (p Tax gene expression was positively correlated with PVL (R = 0.595, p = 0.000) and IL-21 gene expression (R = 0.395, p = 0.021) in the HTLV-1-infected subjects. In conclusion, the increase in IL-21 mRNA expression may reflect the attempt of infected T cells to induce an appropriate antiviral response, and the decrease in IL-21 protein expression may reflect the inhibition of IL-21 mRNA translation by viral factors in favour of virus evasion and dissemination.

In immunosurveillance, bone-derived immune cells infiltrate the tumor and secrete inflammatory cytokines to destroy cancer cells. However, cancer cells have evolved mechanisms to usurp inflammatory cytokines to promote tumor progression. In particular, the inflammatory cytokine, interleukin-1 (IL-1), is elevated in prostate cancer (PCa) patient tissue and serum, and promotes PCa bone metastasis. IL-1 also represses androgen receptor (AR) accumulation and activity in PCa cells, yet the cells remain viable and tumorigenic; suggesting that IL-1 may also contribute to AR-targeted therapy resistance. Furthermore, IL-1 and AR protein levels negatively correlate in PCa tumor cells. Taken together, we hypothesize that IL-1 reprograms AR positive (AR + ) PCa cells into AR negative (AR - ) PCa cells that co-opt IL-1 signaling to ensure AR-independent survival and tumor progression in the inflammatory tumor microenvironment. LNCaP and PC3 PCa cells were treated with IL-1β or HS-5 bone marrow stromal cell (BMSC) conditioned medium and analyzed by RNA sequencing and RT-QPCR. To verify genes identified by RNA sequencing, LNCaP, MDA-PCa-2b, PC3, and DU145 PCa cell lines were treated with the IL-1 family members, IL-1α or IL-1β, or exposed to HS-5 BMSC in the presence or absence of Interleukin-1 Receptor Antagonist (IL-1RA). Treated cells were analyzed by western blot and/or RT-QPCR. Comparative analysis of sequencing data from the AR + LNCaP PCa cell line versus the AR - PC3 PCa cell line reveals an IL-1-conferred gene suite in LNCaP cells that is constitutive in PC3 cells. Bioinformatics analysis of the IL-1 regulated gene suite revealed that inflammatory and immune response pathways are primarily elicited; likely facilitating PCa cell survival and tumorigenicity in an inflammatory tumor microenvironment. Our data supports that IL-1 reprograms AR + PCa cells to mimic AR - PCa gene expression patterns that favor AR-targeted treatment resistance and cell survival. © 2018 Wiley

What caused Chicago bank failures in the Great Depression? A look at the 1920s.

This paper reassesses the causes of Chicago bank failures during the Great Depression by tracking the evolution of their balance sheets in the 1920s. I find that all Chicago banks suffered tremendous deposit withdrawals; however banks that failed earlier in the 1930s had invested more in mortgages in the 1920s. The main problem with mortgages was their lack of liquidity, not their quality. Banks heavily engaged in mortgages did not have enough liquid assets to face the withdrawals and failed....

IL-17-producing NKT cells depend exclusively on IL-7 for homeostasis and survival.

Natural killer T (NKT) cells are innate-like T cells that rapidly recognize pathogens and produce cytokines that shape the ensuing immune response. IL-17-producing NKT cells are enriched in barrier tissues, such as the lung, skin, and peripheral lymph nodes, and the factors that maintain this population in the periphery have not been elucidated. Here we show that NKT17 cells deviate from other NKT cells in their survival requirements. In contrast to conventional NKT cells that are maintained by IL-15, RORγt(+) NKT cells are IL-15 independent and instead rely completely on IL-7. IL-7 initiates a T-cell receptor-independent (TCR-independent) expansion of NKT17 cells, thus supporting their homeostasis. Without IL-7, survival is dramatically impaired, yet residual cells remain lineage committed with no downregulation of RORγt evident. Their preferential response to IL-7 does not reflect enhanced signaling through STAT proteins, but instead is modulated via the PI3K/AKT/mTOR signaling pathway. The ability to compete for IL-7 is dependent on high-density IL-7 receptor expression, which would promote uptake of low levels of IL-7 produced in the non-lymphoid sites of lung and skin. This dependence on IL-7 is also reported for RORγt(+) innate lymphoid cells and CD4(+) Th17 cells, and suggests common survival requirements for functionally similar cells.

Concentrations of polycyclic aromatic hydrocarbons and inorganic constituents in ambient surface soils, Chicago, Illinois: 2001-2002

Kay, R.T.; Arnold, T.L.; Cannon, W.F.; Graham, D.

2008-01-01

Samples of ambient surface soils were collected from 56 locations in Chicago, Illinois, using stratified random sampling techniques and analyzed for polycyclic aromatic hydrocarbon (PAH) compounds and inorganic constituents. PAHs appear to be derived primarily from combustion of fossil fuels and may be affected by proximity to industrial operations, but do not appear to be substantially affected by the organic carbon content of the soil, proximity to nonindustrial land uses, or proximity to a roadway. Atmospheric settling of particulate matter appears to be an important mechanism for the placement of PAH compounds into soils. Concentrations of most inorganic constituents are affected primarily by soil-forming processes. Concentrations of lead, arsenic, mercury, calcium, magnesium, phosphorus, copper, molybdenum, zinc, and selenium are elevated in ambient surface soils in Chicago in comparison to the surrounding area, indicating anthropogenic sources for these elements in Chicago soils. Concentrations of calcium and magnesium in Chicago soils appear to reflect the influence of the carbonate bedrock parent material on the chemical composition of the soil, although the effects of concrete and road fill cannot be discounted. Concentrations of inorganic constituents appear to be largely unaffected by the type of nearby land use. Copyright ?? Taylor & Francis Group, LLC.

Psychiatric Disorders and Substance Use in Homeless Youth: A Preliminary Comparison of San Francisco and Chicago

Full Text Available Youth homelessness is a growing problem in the United States. The experience of homelessness appears to have numerous adverse consequences, including psychiatric and substance use disorders. This study compared the frequencies of psychiatric disorders, including substance use, between homeless youth (18–24 years-old in San Francisco (N = 31 and Chicago (N = 56. Subjects were administered the Mini International Neuropsychiatric Interview (M.I.N.I. to assess DSM-IV-TR diagnoses and substance use disorders. Eighty-seven percent of the San Francisco youth, and 81% of the Chicago youth met criteria for at least one M.I.N.I. psychiatric diagnosis. Nearly two-thirds of the youth in both samples met criteria for a mood disorder. Approximately one-third met criteria for an anxiety disorder. Thirty-two percent of the San Francisco sample and 18% of the Chicago met criteria for Antisocial Personality Disorder. Approximately 84% of the San Francisco youth and 48% of the Chicago youth met criteria for a substance-related disorder, and more substances were used by San Francisco youth. In conclusion, the high rate of psychiatric disorders in homeless youth provides clear evidence that the mental health needs of this population are significant. Implications are discussed.

A tale of two cities: residential context and risky behavior among adolescents in Los Angeles and Chicago.

Science.gov (United States)

Frank, Reanne; Bjornstrom, Eileen

This article evaluates whether the at-risk behavior of adolescents is differentially influenced by community context across two metropolitan areas. Our focus is on Latino youth in particular. The data come from the Los Angeles Family and Neighborhood Survey (L.A.FANS) and the Project on Human Development in Chicago Neighborhoods (PHDCN). Multi-level models are employed to estimate the effects of community-level influences on adolescent risky behavior in Los Angeles and Chicago. Neighborhood-level influences on the at-risk behavior of youth are found to operate similarly across the two cities, such that native-born children of Latino immigrants are at greatest risk of problem behavior in co-ethnic highly segregated neighborhoods in both Los Angeles and Chicago. Similar patterns are observed for African-Americans, particularly in Chicago and Non-Latino Whites in both cities. We argue that the findings are best interpreted through a segregation framework. Members of each racial/ethnic group appear to exhibit negative health risk behaviors when they reside in areas that are disproportionately populated with their co-ethnic peers.

Full Text Available Daniel Hudson Burnham, the Chicago architect and city planner, is recognized for his work on the development of American tall office building; for the construction of World’s Columbian Exposition of 1893; and for his city plans for Washington, D.C., Cleveland, San Francisco, and Chicago. He is also remembered for the quote “Make no little plans.” What is not recalled is his Swedenborgian faith nor how it influenced his work. Emanuel Swedenborg was a Swedish scientist and engineer who, beginning in the mid 1730s, underwent a spiritual awakening. The focus of his work changed to the mystical aspects of human experience. He believed that all Christian churches were dead and in need of revitalization and the key to revitalization was to be found in a new interpretation of scripture. His followers founded the Church of the New Jerusalem, sometimes referred to as the New Church or the Swedenborgian Church.

A heterogeneous group of patients, including 51 patients with pemphigus vulgaris, one with pemphigus vegetans, nine with pemphigus foliaceus, five with paraneoplastic pemphigus, four with epidermolysis bullosa acquisita, and one with both bullous pemphigoid and graft vs host disease was included in this survey. Overall the monoclonal antibody seems to be effective in that 69% of patients showed complete response, 25% of patients showed partial response, whereas 6% of patients showed progressive disease. Six deaths occurred in association with the treatment, with four of these deaths in patients with paraneoplastic pemphigus, a disease characteristically resistant to conventional medication and with a high mortality rate. Of note, 11 patients who received combined rituximab and intravenous immune globulin treatments had the best outcome: complete response without any serious side effects. Therefore further investigation on rituximab with controlled clinical trial is a worthy pursuit.Keywords: blistering diseases, skin, anti-CD20, pemphigus, epidermolysis bullosa acquisita

Hydrology of and Current Monitoring Issues for the Chicago Area Waterway System, Northeastern Illinois

Science.gov (United States)

Duncker, James J.; Johnson, Kevin K.

2015-10-28

The Chicago Area Waterway System (CAWS) consists of a combination of natural and manmade channels that form an interconnected navigable waterway of approximately 90-plus miles in the metropolitan Chicago area of northeastern Illinois. The CAWS serves the area as the primary drainage feature, a waterway transportation corridor, and recreational waterbody. The CAWS was constructed by the Metropolitan Water Reclamation District of Greater Chicago (MWRDGC). Completion of the Chicago Sanitary and Ship Canal (initial portion of the CAWS) in 1900 breached a low drainage divide and resulted in a diversion of water from the Lake Michigan Basin. A U.S. Supreme Court decree (Consent Decree 388 U.S. 426 [1967] Modified 449 U.S. 48 [1980]) limits the annual diversion from Lake Michigan. While the State of Illinois is responsible for the diversion, the MWRDGC regulates and maintains water level and water quality within the CAWS by using several waterway control structures. The operation and control of water levels in the CAWS results in a very complex hydraulic setting characterized by highly unsteady flows. The complexity leads to unique gaging requirements and monitoring issues. This report provides a general discussion of the complex hydraulic setting within the CAWS and quantifies this information with examples of data collected at a range of flow conditions from U.S. Geological Survey streamflow gaging stations and other locations within the CAWS. Monitoring to address longstanding issues of waterway operation, as well as current (2014) emerging issues such as wastewater disinfection and the threat from aquatic invasive species, is included in the discussion.

The role of single nucleotide polymorphism of IL-6 and IL-10 cytokine on pain severity and pain relief after radiotherapy in multiple myeloma patients with painful bone destructions

Directory of Open Access Journals (Sweden)

Rudzianskiene Milda

2014-01-01

Full Text Available Multiple myeloma (MM cells interact with bone marrow stromal cells stimulating transcription and secretion of cytokines like IL-6 and IL-10, which are implicated in the progression and dissemination of MM. Regulation of cytokines secretion is under genetic control through genetic polymorphisms in their coding and promoter sequences. It seems that single nucleotide polymorphism (SNP in the promoter region of various genes may regulate the plasma concentrations of cytokines. Cytokines could be also hypothesized to function as pain modulators as peripheral nociceptors are sensitized by cytokines. The aim was to determine if the SNP of IL-6 and IL-10 cytokines could influence the analgesic response of radiotherapy in the treatment of painful bone destructions in MM patients. 30 patients (19 women and 11 men, median age: 67 years with MM and painful bone destructions were treated with palliative radiotherapy. Pain was evaluated according to the visual analogue scale and analgesics intake. Pain scores and analgesics use were measured prior to radiotherapy as well as 4, 12 and 24 weeks afterward. Opioid analgesics were converted to the morphine-equivalent daily dose (MEDD. Genomic DNA was extracted from peripheral blood leukocytes and IL-6 and IL-10 gene promoter polymorphisms were analysed with polymerase chain reaction. 60% of patients reported severe pain prior to radiotherapy, which decreased to 13% at the first follow-up visit (p <0.001. The MEDD on admission to the hospital was 75 mg/day which decreased to 46 mg/day at the first follow-up visit (p = 0.033. A significant parameter in pain relief was: age < 65 years (p=0.029. We analysed 6 SNPs in the gene promoter region of IL-6 (-597 G/A, -572 G/C, -174 G/C and IL-10 (-592 A/C, -819 C/T, -1082 A/G as well as their relation with pain severity and analgesic consumption. Patients who are IL-10 -1082 A/G carriers are prone to respond better to radiotherapy than other patients (p<0.05. A borderline

Aspirin hypersensitivity is a hallmark of aspirin-exacerbated respiratory disease (AERD), a clinical syndrome characterized by the severe inflammation of the respiratory tract after ingestion of cyclooxygenase-1 inhibitors. We investigated the capacity of aspirin to induce interleukin-4 (IL-4) production in inflammatory cells relevant to AERD pathogenesis and examined the associated biochemical and molecular pathways. We also compared IL-4 production in peripheral blood mononuclear cells (PBMCs) from patients with AERD vs aspirin-tolerant asthma (ATA) upon exposure to aspirin. Aspirin induced IL-4 expression and activated the IL-4 promoter in a report assay. The capacity of aspirin to induce IL-4 expression correlated with its activity to activate mitogen-activated protein kinases, to form DNA–protein complexes on P elements in the IL-4 promoter and to synthesize nuclear factor of activated T cells, critical transcription factors for IL-4 transcription. Of clinical importance, aspirin upregulated IL-4 production twice as much in PBMCs from patients with AERD compared with PBMCs from patients with ATA. Our results suggest that IL-4 is an inflammatory component mediating intolerance reactions to aspirin, and thus is crucial for AERD pathogenesis. PMID:27534531
