    Full Text Available Ma (2009 is a single channel video of a mother and child walking together side by side, holding hands. The title is reminiscent of the affectionate nickname for a mother, 'Ma', but also a concealed way to convey maternal ambivalence. Maternal ambivalence is the result of the tension between the idealisation of motherhood and women’s lived experience of mothering. The maternal struggle finds its source in the difficulty of identifying with the ideological representation of the mother. This image still conveys an idealistic and nostalgic, patriarchal image of maternal love bounded by culture and history. http://podcast.ulcc.ac.uk/accounts/BirkbeckCollege/mamsie/MA.mov

    Full Text Available Il dolore è l’aspetto negativo di un sistema sensitivo indispensabile alla vita, detto sistema nocicettivo, dal latino noxa e nocēre. I bambini con difetti congeniti della trasmissione o dell’elaborazione percettiva dei segnali dolorifici (analgesia congenita vanno incontro ad una serie di lesioni di cui non si accorgono, sempre più gravi. Crescendo, possono riconoscere il pericolo attraverso l’educazione e l’esperienza, ma, senza l’allarme dato dal dolore, molte malattie possono evolvere senza che siano combattute per tempo, in una spirale che spesso conduce al decesso.

Ma dall’approfondimento di tali meccanismi emerge anche la potenzialità conoscitiva del gioco, come condizione umana di profonda consapevolezza di sé. Attraverso un percorso che passa attraverso Breton, Platone, Huizinga, e Alessandro Fersen, viene qui proposta una lettura del gioco come carattere fondamentale dell’arte e della conoscenza.

  8. En Inde, dans les salles de cinéma, les spectateurs sont-ils acteurs ou simples spectateurs ? In Indian cinemas, can members of the audience be qualified as actors or simply spectators?

    Directory of Open Access Journals (Sweden)

    Wendy Cutler

    2012-04-01

    Full Text Available Si la question du rôle du spectateur peut se poser sur un plan général, elle prend une dimension particulière lorsque l’on se penche sur le cas des spectateurs indiens. En effet, en Inde, depuis les débuts du cinéma, le public ne se contente pas d’être seulement spectateur des œuvres projetées. Il se démarque ainsi du rôle qui lui avait été originairement attribué dans l’épopée indienne le Ramayana où il assistait sans réagir au sacrifice de Sita. On peut donc se demander s’il conviendrait de lui attribuer le qualificatif de « spectacteur », néologisme utilisé dans le cadre des SIC1. Pour répondre à cette interrogation, nous remonterons aux premières réflexions portant sur le public de théâtre, dominées par la notion aristotélicienne de catharsis. De là, nous ferons un parallèle avec le « contrat de feintise » évoqué dans le Nâtya-Shâstra (ou traité de théâtre indien, et verrons dans quelle mesure ce contrat entre le spectateur et l’œuvre peut s’appliquer au public de cinéma en Inde. Par la suite, dans une étude plus générale de la place du spectateur d’œuvres cinématographiques, nous expliquerons en quoi les spectateurs indiens se différencient, ne serait-ce que dans leurs attitudes lors des projections filmiques, des spectateurs occidentaux. Cela nous conduira à aborder la question de l’interactivité entre le public et l’œuvre, et à déterminer de quelle manière le public peut interagir sur une œuvre projetée.The spectator’s role in general is often questioned, but in the case of Indian spectators, it takes a whole new turn. Indeed, in India, since the arrival of cinema, members of the audience do not content themselves with being simply spectators of the films projected. In that way, they distinguish themselves from their original role attributed by the epic poem, the Ramayana, in which they watched Sita’s sacrifice without reacting. Therefore, we can ask

    Full Text Available Il muro, nel suo grigio rigore formale, nella sua fredda geometria, nel suo intento divisorio, nasconde spesso il cielo. Sovente il linguaggio dell’arte, ma non di meno quello della comunicazione, hanno interferito con le sue algide barriere. In molti casi, beninteso, non è che il potere in altre forme, che interferisce con se stesso: pensiamo ai bandi affissi agli angoli delle città, o le lettere d’indulgenza papali -spesso impreziosite da miniature al punto da poterle considerare antenate dal manifesto- che nel corso del medioevo venivano affisse sulle porte delle chiese.

    Davvero esistono “lì fuori” leggi di natura, che stanno in attesa di essere scoperte, indipendenti dal nostro modo di pensare, o esse rappresentano soltanto la descrizione più conveniente di ciò che abbiamo visto? Come è nata l’idea stessa di “leggi di natura”? Queste costituiscono la realtà profonda o sono soltanto pezzi di un regolamento che ci siamo dati per organizzare meglio la nostra conoscenza del mondo? o semplici paletti che piantiamo e ci lasciamo alle spalle come segnali via via che procediamo nella giungla dell’esperienza? È possibile che non esistano affatto leggi di natura? Forse esse, e anche l’universo che da esse sembra regolato, sono del tutto creazioni della nostra mente: un’illusione che scompare appena cessiamo di pensarvi. Ma allora, che cosa accadrebbe, se non ci fossero osservatori dell’universo?». Interrogativi di questo genere, che incontriamo sulla soglia del Mondo dentro il mondo, sarebbero suonati eccentrici fino a qualche anno fa. Oggi, al contrario, circ...

Questa definizione, basata sulla nostra esperienza soggettiva, è generale, ampiamente condivisa, ma chiaramente pre-scientifica. Una definizione scientifica di coscienza presuppone che si affronti (e che si risolva il problema cervello-coscienza. In sostanza, risolvere questo problema significa rispondere alla seguente domanda: “come fa un pugno di neuroni racchiuso nel cranio ad ospitare un soggetto che vede rosso?”. I filosofi chiamano questo problema “the hard problem” (il problema difficile e molti ritengono che non sia affrontabile scientificamente; assumendo una posizione ancora più radicale, alcuni filosofi negano che vi sia un rapporto causale tra l’attività del cervello e la nostra esperienza soggettiva.

    The Space Exploration Division of the Safety and Mission Assurances Directorate is responsible for reducing the risk to Human Space Flight Programs by providing system safety, reliability, and risk analysis. The Risk & Reliability Analysis branch plays a part in this by utilizing Probabilistic Risk Assessment (PRA) and Reliability and Maintainability (R&M) tools to identify possible types of failure and effective solutions. A continuous effort of this branch is MaRS, or Mass and Reliability System, a tool that was the focus of this internship. Future long duration space missions will have to find a balance between the mass and reliability of their spare parts. They will be unable take spares of everything and will have to determine what is most likely to require maintenance and spares. Currently there is no database that combines mass and reliability data of low level space-grade components. MaRS aims to be the first database to do this. The data in MaRS will be based on the hardware flown on the International Space Stations (ISS). The components on the ISS have a long history and are well documented, making them the perfect source. Currently, MaRS is a functioning excel workbook database; the backend is complete and only requires optimization. MaRS has been populated with all the assemblies and their components that are used on the ISS; the failures of these components are updated regularly. This project was a continuation on the efforts of previous intern groups. Once complete, R&M engineers working on future space flight missions will be able to quickly access failure and mass data on assemblies and components, allowing them to make important decisions and tradeoffs.

    2006-01-01

    Da quando l'universo ha avuto inizio, ha cominciato a calcolare il proprio comportamento. All'inizio il computer-universo produceva strutture semplici, particelle elementari e leggi elementari della fisica; col passare del tempo ha processato "informazioni" sempre più complesse, producendo strutture sempre più intricate (galassie, stelle, pianeti), ma sempre secondo leggi semplici. Ogni cosa deve quindi la propria esistenza alla capacità intrinseca della materia e dell'energia di processare informazione. Se si decifrasse fino in fondo si potrebbe, con un computer quantistico di dimensioni ridotte, comprendere l'universo nel suo insieme.

    Full Text Available Oggi la teoria della conservazione urbana sta affrontando aspetti intangibili – notabilmente il concetto del “genius loci”. Ma questa idea potenzialmente vaga deve essere compresa nei termini che permettono un suo effettivo utilizzo. L’autore argomenta che tale questione può essere affrontata attraverso un approfondimento della complessità della scienza rivelando i modi attraverso i quali un sistema nella sua interezza può essere scomposto in elementi dinamici. All’interno dei tessuti storici noi siamo conservatori, siamo utilizzatori, siamo consumatori e, inevitabilmente, siamo coloro che attuano le modifiche. Il nostro compito non è di far resistere quell’insieme, ma di poterlo gestire in maniera più dinamica e di pretendere un più ampio concetto di conservazione. Questo atteggiamento va oltre il dualismo basato sul modello di pensiero del “genius loci” ma abbraccia una più efficace aspettativa di crescita organica.

Ma quale rappresentazione della “mente bilingue” hanno i parlanti una o più lingue? Come immaginano la testa di chi e bilingue e dove collocano le diverse parole? Abbiamo chiesto agli alunni, piccoli e grandi, di alcune scuole di “disegnare il bilinguismo”: emergono in maniera vivida i “posti” diversi in cui le lingue si installano, i dubbi e le spiegazioni dei bambini, la necessità del controllo e la coloritura affettiva dell’uno e dell’altro idioma.  Drawing bilingualism The theme of linguistic diversity and the recognition and appreciation of forms of bilingualism in children and young people is crucial in a multilingual, multicultural school environment. But how do speakers of one or more languages imagine a “bilingual mind”? How do they imagine a bilingual person’s head and where are the different words located? We asked school children to “draw bilingualism”. The “placement” of the different languages, the children’s doubts and explanations and their need to check and the affective coloring of one and the other language emerged.

Christopher Rundle parte da lì per un importante studio sul "problema delle traduzioni" durante il fascismo, Publishing Translations in Fascist Italy, Peter Lang, 2010. Riesce così a fornire un panorama convincente di uno dei dibattiti più caratteristici del Ventennio, e a ridiscutere alcuni assunti come la centralità della letteratura anglo-americana nelle preoccupazioni dei "censori". Perché di amministrazione della cultura si parla: della censura porosa e discontinua – o comunque tardiva – messa in atto dal fascismo per limitare “l’invasione delle traduzioni”. Un interesse, quello nei confronti della politica e della censura editoriale durante i fascismi che sembra ormai centrale negli studi di italianistica e traduttologia.Il secondo volume recensito - Christopher Rundle and Kate Sturge, Translation under Fascism, Palgrave Macmillan, 2010 presenta una serie di studi sullo statuto delle traduzioni durante i regimi totalitari. Questa collezione di saggi va oltre i confini italiani e tedeschi e si occupa delle politiche di traduzione dei regimi fascisti europei, contribuendo ad allargare e mettere in discussione non solo la nostra conoscenza delle pratiche censorie in diversi ambiti espressivi, ma anche la stessa idea di regime fascista.

Questa teoria ha come perno la nozione di gioco: e non già in una o più delle innumerevoli accezioni della parola, ma in tutte, con l’aggiunta di una ulteriore accezione che sottende tutte le altre: il gioco come struttura intelligibile emergente dal divenire caotico, quindi come fenomeno «che ha guidato fin dall’inizio il corso dell’Universo».

    Directory of Open Access Journals (Sweden)

    Ankit Shah

    Full Text Available HIV-1 envelope protein gp120 has been extensively studied for neurotoxic effects that have been attributed to the increased expression of various proinflammatory cytokines in the CNS. Recently we have shown that methamphetamine (MA also increases expression of proinflammatory cytokines in astrocytes. However, combined effect of gp120 and MA is not known. The present study was undertaken to determine cumulative effect and the mechanism(s/pathways involved in the functional interaction between gp120 and MA in SVGA astrocytes. Our results clearly suggest that gp120 and MA affect IL-6 but not IL-8 in a synergistic manner and this synergy was mediated by PI3K/Akt and NF-κB pathways. Inhibition of either of these pathways could abrogate the increased expression of IL-6 due to MA or gp120 alone, as well as the increased expression of IL-6 when the astrocytes were treated with both gp120 and MA. These results were confirmed by both, using chemical inhibitors/siRNA as well as western blotting. This study therefore provides novel information regarding the interaction between MA and gp120 in terms of the expression of IL-6 and the mechanisms underlying potential synergy between MA and gp120 in astrocytes.

  18. Il desiderio dell’analista e la trasmissione della psicanalisi

    Full Text Available Il desiderio dello psicanalista rappresenta il fondamento della cura psicanalitica stessa, senza di esso non potrebbe esserci una psicanalisi, né nella sua pratica clinica, né nella sua articolazione teorica, né nella sua trasmissione. Il desiderio dello psicanalista si distin-gue dalla struttura fantasmatica del desiderio patologico e prende forma, invece, dal desi-derio etico. Il desiderio etico comporta che il soggetto riesca a recuperare una relazione di giustezza rispetto al proprio desiderio e ai propri atti. Il desiderio etico riguarda il soggetto dell’azione, è un desiderio essenziale. L’analizzante che riesce a portare a termine la sua analisi sarà riuscito a saperci fare col proprio desiderio al punto da poterne individuare uno proprio come psicanalista che gli consentirà non solo di poter condurre delle analisi, a sua volta, ma anche di dare un suo unico e singolare apporto alla trasmissione della psicanalisi stessa.

    Full Text Available Pensiamo che il Prof. Luca Surian, psicologo e ricercatore dell’Università di Trento, abbia saputo, con la sua introduzione sullo stato della ricerca in psicologia morale - pubblicata per il Mulino con il titolo "Il giudizio morale" (2013 - realmente fornire al lettore utili stimoli per avvicinarsi alla materia, o per farsi una prima idea, ma vera (e vera perché chiara, dei temi in argomento. Abbiamo voluto intervistare l'Autore per riflettere assieme su alcune questioni che ci sono sembrate centrali, controverse o, semplicemente, curiose.

    This final report for Project 117863 summarizes progress made toward understanding how X-pinch load designs scale to high currents. The X-pinch load geometry was conceived in 1982 as a method to study the formation and properties of bright x-ray spots in z-pinch plasmas. X-pinch plasmas driven by 0.2 MA currents were found to have source sizes of 1 micron, temperatures >1 keV, lifetimes of 10-100 ps, and densities >0.1 times solid density. These conditions are believed to result from the direct magnetic compression of matter. Physical models that capture the behavior of 0.2 MA X pinches predict more extreme parameters at currents >1 MA. This project developed load designs for up to 6 MA on the SATURN facility and attempted to measure the resulting plasma parameters. Source sizes of 5-8 microns were observed in some cases along with evidence for high temperatures (several keV) and short time durations (<500 ps).

  2. IL CAMPO GEOMAGNETICO

    Directory of Open Access Journals (Sweden)

    F. MOLINA

    1972-06-01

    Full Text Available Questo lavoro non è un trattato sul campo geomagnetico e nemmeno
    una rassegna sull'argomento, almeno nel significato che normalmente
    si attribuisce al termine « rassegna »; esso è semplicemente
    un tentativo di condensare in termini comprensibili agli studiosi non
    specializzati ciò che oggi si sa o si ipotizza sul magnetismo terrestre
    e sulle sue cause. Chi scrive si è sempre trovato a disagio di fronte
    alle richieste di una spiegazione sull'origine del campo magnetico
    terrestre: o si cerca di cavarsela con poche parole (« si tratta di correnti
    elettriche indotte nell'interno della Terra » che possono forse accontentare
    chi non si occupa in modo particolare di problemi scientifici
    ma non possono soddisfare un fisico, oppure ci si sente obbligati a
    tentare faticosamente di approfondire, sia per capirli personalmente
    che per poterli poi spiegare agli altri, argomenti e ragionamenti che
    sono in realtà accessibili solo a un fisico teorico ben preparato. Apparentemente
    non esiste una via di mezzo, come del resto in molti altri
    campi della fisica contemporanea.
    La presente monografia rappresenta appunto il tentativo di trovare
    questa via di mezzo: nel terzo capitolo, dedicato alle teorie sull'origine
    del campo geomagnetico, si cerca di descrivere qualitativamente
    i principali processi fisici proposti come sorgenti del campo,
    dopo un accenno ai fondamenti fisici e matematici sui quali sono state
    elaborate le varie teorie. Senza farmi soverchie illusioni di essere riuscito
    nell'intento, mi dichiarerei tuttavia soddisfatto se questo lavoro
    destasse sull'argomento l'interesse di qualche giovane ricercatore, incoraggiandolo
    ad un approfondimento.

  3. Il rumore elettrico Dalla fisica alla progettazione

    CERN Document Server

    Pallottino, Giovanni Vittorio

    2011-01-01

    L’opera fornisce una trattazione chiara, agile ed essenziale, ma completa, del rumore elettrico, argomento considerato generalmente oscuro e specialistico. Molto più breve (circa 275mila battute) dei testi attualmente disponibili. Il contenuto copre gli aspetti essenziali della matematica e della fisica del rumore (termico, shot. 1/f, …), e della sua rappresentazione nei circuiti. Discute quindi il rumore nei dispositivi passivi e attivi, e introduce i criteri di progettazione a basso rumore. Affronta infine brevemente questioni quali l’estrazione del segnale dal rumore e gli impieghi utili del rumore. L’attenzione è generalmente rivolta alla strumentazione fisica a bassa frequenza, in relazione alla pluridecennale esperienza specifica dell’autore. Si tratta di una estensione delle dispense, utilizzate per anni, di un corso universitario. Pertanto la trattazione è fortemente didattica, con particolare attenzione a rimuovere ambiguità e incertezze, discutendo il materiale in termini fisici intuit...

    2016-01-01

    In 1931, Dirac advanced a startling prediction about the existence of a new elementary particle, characterized by a magnetic charge of a single polarity: the magnetic monopole. This prediction, that was not based on experimental reasons but on mathematical consistency considerations and the generalization of the formalism of quantum mechanics, illustrates emblematically the Dirac conception of the relationship between physics and mathematics. ----- Nel 1931 Dirac avanz\\`o una sorprendente previsione circa l'esistenza di una nuova particella elementare, caratterizzata da una carica magnetica di un'unica polarit\\`a: il monopolo magnetico. Questa previsione, che non era fondata su ragioni sperimentali ma su considerazioni di consistenza matematica e sulla generalizzazione del formalismo della meccanica quantistica, illustra emblematicamente la concezione di Dirac del rapporto tra fisica e matematica.

    2009-12-01

    Full Text Available Il contributo si concentra sull'origine del toponimo Nimis, località a nord di Udine, il cui nome è attestato per la prima volta in Paolo Diacono. Per quanto riguarda l'etimo, l'unico in circolazione risulta esser quello proposto da F. Schürr (1930, secondo il quale il toponimo friulano risalirebbe ad una forma celtica affine alla denominazione in età classica della città di Nîmes (provenzale Nemse, cio è Nemausus. Contrariamente a tale interpretazione, l'autore raccoglie indizi a favore dell'eventualità che il toponimo sia di origine slava, riconducendolo ad un prototipo paleoslavo němici. La forma Nimis sarebbe il risultato della 'friulanizzazione' del lessema slavo presente nel dialetto sloveno della valle del Torre situata a poca distanza dalla località friulana in questione.

    Full Text Available Dopo 19 anni arriva la Legge. Al via il doppio canale. Il 19 dicembre 2012 è stata e sarà una data epocale nel panorama professionale italiano. Dopo 19 anni da quella prima bozza che prevedeva la regolamentazione delle associazioni professionali (in applicazione della Direttiva UE 92/51, passando per svariate proposte di Legge, siamo arrivati finalmente al riconoscimento. Non “ordini professionali di serie B” – come subito qualche preoccupato psicologo si è premurato di precisare – ma l’attuazione del così detto doppio binario: ordini da una parte con il loro albo, associazioni professionali dall’altra con il loro registro. È stata una battaglia che ha richiesto molta resistenza: una battaglia per la modernizzazione del sistema professionale italiano, per il riconoscimento sociale e politico di oltre 3.000.000 di professionisti, fino ad oggi ingiustamente discriminati poiché privi di qualunque tutela.

    Full Text Available La psicoanalisi lacaniana può essere utilizzata per riflettere sul sottile e invisibile processo di rappresentazione simbolica, nel contesto della stereotipizzazione e della de-umanizzazione che troviamo in opera nello stile paranoico della politica (per esempio, nelle teorie del complotto. L’articolo evidenzia come la pretesa di immunizzazione auto-conservativa sia indispensabile nei processi di soggettivazione politica, ma può produrre un rovesciamento distruttivo. Nella identità comunitaria paranoica, la negatività è cancellata e il male, kakon, proiettato su un Altro persecutorio. L’ultima parte dell’articolo mette a fuoco il nesso tra paranoia e psicosi nelle forme di violenza gratuita, terrorismo e droga, nel sistema post-totalitario neoliberale. Solo l’assunzione del fantasma (che organizza il nostro sguardo sul mondo e il suo attraversamento, può aiutare ad aprire il circolo paranoico dell’identità.

Ciò che sono sta lì nelle mille scintille dell’universo umano che osservo e che si riflettono nella struttura policroma del pensiero e dei suoi rimandi ad altri. Sono stufo dell’eterna e sterile liturgia dell’oggettività di una para-natura. Che solo lei sappia nutrire i pensieri e fondare il canone che rende infecondo il pensare con la generazione di pensieri che non osano perché inautentici e dunque disonesti. Non ci si può cristallizzare fra numeri e numeretti - che poi mica tanto sono conosciuti – ma val la pena emozionare.

    Full Text Available La letteratura ha una funzione etica cui non può rinunciare. Il letterato, la figura più importante su un territorio, ha il compito di leggere la realtà, di interpretarla, di comunicarla. È il faro che si deve accendere e guidare le azioni degli uomini: un popolo che rinuncia ai suoi letterati e all’etica della letteratura, è un popolo che si perde. Così egli canta la Negritudine, la storia e il dolore della sua gente; e la sua poesia, con un forte impegno civile, si propone di dar voce a chi non ce l’ha.  The poet and his times Literature has an undeniable ethical function. The writer, the most important figure in a place, has the task of reading, interpreting and communicating reality. Literature is the beacon that one turns to and that guides the actions of people. A country that renounces its writers and the ethics of literature is a lost nation. Thus the writer sings of Negritude, the history and the pain of his people. Her poetry, with strong social commitment, aims to give voice to those who do not have one.

    To investigate the effect of TGF-β1 on the expressions of IL-12, IL-15, IL-18, IL-4 and IL-10 in heart transplantation rejection in rats, a model of rat cervical heterotopic heart transplanta-tion was set up and the model rats were randomly divided into three groups: control group, transplant group and TGF-β1 group. The mRNA expression levels of IL-12, IL-15, IL-18, IL-4 and IL-10 were determined by RT-PCR at the 5th day after the transplantation. The mRNA expression levels of IL-12,IL-15, IL-18 were increased obviously and those of IL-4, IL-10 were significantly decreased in the transplant group as compared with the control group (P<0.01). In the TGF-β1 group, the mRNA ex-pression levels of IL-12, IL-15, IL-18 were significantly decreased and those of IL-4, IL-10 were sig-nificantly increased as compared with the transplant group (P<0.01). The immunosuppressive effect of TGF-β1 on heart transplantation rejection was related to its inhibition of the expressions of Th1-type cytokines (IL-12, IL-15, IL-18 etc) and its promotion of the expressions of Th2-tpye cyto-kines (IL-4, IL-10).

    Every nucleated cell can produce and respond to cytokines, extracellular proteic/glycoproteic mediators that constitute a complex, interconnected, and flexible signaling network, addressed to modulate cell behavior and homeostasis through the interaction with high-affinity surface receptors. These messenger molecules, whose main characteristics are potency, pleiotropism, and redundancy, primarily act in autocrine, paracrine, and juxtacrine way, but can also display systemic activity in endocrine-like modality. They are generally classified according to their cellular sources, three-dimensional structure, or biological functions. Among cytokines, interleukins (ILs) represent a fascinating and multifunctional group of immunomodulators that primarily mediate the leukocyte cross-talk (hence the name), and mainly regulate the immune cell proliferation, differentiation, growth, survival, activation, and functions. Up to 38 ILs have been so far identified, numbered according to the order of discovery, and grouped in different subsets, based on distinguishing structural/functional features. Due to their crucial role in regulating inflammation and immune response, ILs are known to be involved in the pathogenesis of human inflammatory/autoimmune diseases. Therefore, they have increasingly attracted great interest as effective or promising therapeutic targets. The biology and functions of the hitherto identified human ILs are reviewed and discussed: herein, ILs from IL-20 to IL-38 are presented.

    IL-4 and IL-13 are pleiotropic Th2 cytokines produced by a wide variety of different cell types and responsible for a broad range of biology and functions. Physiologically, Th2 cytokines are known to mediate host defense against parasites but they can also trigger disease if their activities are dysregulated. In this review we discuss the rationale for targeting the IL-4/IL-13 axes in asthma, atopic dermatitis, allergic rhinitis, COPD, cancer, inflammatory bowel disease, autoimmune disease and fibrotic disease as well as evaluating the associated clinical data derived from blocking IL-4, IL-13 or IL-4 and IL-13 together.

    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.

    IL-33 is a proinflammatory cytokine that is a member of IL-1 family. Previously the effect of IL-33 on kidney injury is showed in animal models. In this study, we searched if we can use IL-33 to show the early stage of kidney injury in diabetic patients. Three groups are identified: 26 patients in Group 1: Healthy group, that do not have any chronic diseases and not taking any medication; 42 patients in Group 2: DM (diabetes mellitus) group without any known kidney disease and with normal kidney functions; 32 patients in Group 3: DM + MA (microalbuminuria) group that are assumed to have nephropathy. IL-33 level of DM patient group is greater than healthy group; also IL-33 level of DM + MA patient group is greater than healthy group; but there is not any difference between DM and DM + MA group. The increase in IL-33 levels in diabetic nephropathy is not associated with kidney injury but the increase could be resulting because of diabetes. So IL-33 cannot be used in early recognition of diabetic nephropathy.

    Interleukin (IL)-4 and IL-13 were discovered approximately 30years ago and were immediately linked to allergy and atopic diseases. Since then, new roles for IL-4 and IL-13 and their receptors in normal gestation, fetal development and neurological function and in the pathogenesis of cancer and fibrosis have been appreciated. Studying IL-4/-13 and their receptors has revealed important clues about cytokine biology and led to the development of numerous experimental therapeutics. Here we aim to highlight new discoveries and consolidate concepts in the field of IL-4 and IL-13 structure, receptor regulation, signaling and experimental therapeutics.

Il sabba era, dunque, uno dei luoghi ove si cristallizzavano le figure del proibito, questo per il suo carattere sacro, per la violenza istituzionale che presiedeva alla formazione dei rapporti sociali, e conferiva anche, per le caratteristiche di protesta che rivela, un'immagine sempre esaltante della capacità delle società a resistere. Il problema della nostra epoca ove rifioriscono le streghe nelle più svariate forme è, forse, quello di riallacciarsi con la dimensione gruppale dei nostri svaghi, nelle loro differenti forme e, contemporaneamente, con perdita di energia, a quanto presiedeva ai sabba e alla loro risoluzione sacrificale.

    Full Text Available The interleukin (IL-12 family, which is composed of heterodimeric cytokines including IL-12, IL-23, and IL-27, is produced by antigen-presenting cells such as macrophages and dendritic cells and plays critical roles in the regulation of helper T (Th cell differentiation. IL-12 induces IFN- production by NK and T cells and differentiation to Th1 cells. IL-23 induces IL-17 production by memory T cells and expands and maintains inflammatory Th17 cells. IL-27 induces the early Th1 differentiation and generation of IL-10-producing regulatory T cells. In addition, these cytokines induce distinct immune responses to tumors. IL-12 activates signal transducers and activator of transcription (STAT4 and enhances antitumor cellular immunity through interferon (IFN- production. IL-27 activates STAT1, as does IFN- and STAT3 as well, and enhances antitumor immunity by augmenting cellular and humoral immunities. In contrast, although exogenously overexpressed IL-23 enhances antitumor immunity via memory T cells, endogenous IL-23 promotes protumor immunity through STAT3 activation by inducing inflammatory responses including IL-17 production.

    2015-09-01

    Aberrant production of the prototypical type 2 cytokines, interleukin (IL)-4 and IL-13 has long been associated with the pathogenesis of allergic disorders. Despite tremendous scientific inquiry, the similarities in their structure, and receptor usage have made it difficult to ascertain the distinct role that these two look-alike cytokines play in the onset and perpetuation of allergic inflammation. However, recent discoveries of differences in receptor distribution, utilization/assembly and affinity between IL-4 and IL-13, along with the discovery of unique innate lymphoid 2 cells (ILC2) which preferentially produce IL-13, not IL-4, are beginning to shed light on these mysteries. The purpose of this chapter is to review our current understanding of the distinct roles that IL-4 and IL-13 play in allergic inflammatory states and the utility of their modulation as potential therapeutic strategies for the treatment of allergic disorders.

    2012-11-01

    Full Text Available This work focuses on the pathological power of the ego, understood as an existential illness which has at its confused and blurred centre the lack of distinctions between opposites. In a certain sense there is no element without its opposite. However, the principle of separation allows the freedom of choice entrusted to each of us. Adolf and Superman represent two heroes; the first embodies evil, the second good. But both pose the same objective: the fight against others for the victory of what they consider good or bad. Both are the image of the ego and, therefore, power. Both are therefore victims of paranoia. This paranoia is also typical of contemporary society, in which the confused center of paranoia takes the side of the ego in many ways. In fact, the paranoiac ignores the center, that is, its essence, because it loses its ties with the origin and the simplicity to replace it with superstructures of ideas and projects that are driving it away from itself, often increasing its confusion and, therefore, its bondage.

    Full Text Available In quest’articolo propongo un’analisi di una teoria della razionalità, il modello Belief-Desire-Intention (BDI, con l’obiettivo di stabilirne la fecondità teoretica. Interpreto il modello come il risultato dell’indebolimento di alcuni principi cardine della teoria della scelta razionale: se questa è di natura normativa e considera agenti altamente idealizzati, il modello BDI è invece motivato dallo scopo di dare una caratterizzazione cognitivamente plausibile delle azioni degli individui e inserisce nella definizione di razionalità aspetti non normativi. Per questa ragione, la teoria BDI introduce il concetto di intenzione e complica la propria ontologia: le intenzioni pongono dei vincoli di consistenza sulla componente motivazionale dell’individuo e fungono da filtro di ammissibilità sulla selezione di altre intenzioni (Bratman, 1987. Presento ed analizzo di seguito due formalizzazioni, sviluppatesi in due diverse aree di ricerca (logica e intelligenza artificiale, dei principi filosofici della teoria: il sistema BDICTL*-W3 (Georgeff e Rao, 1998 ed un esempio di Agent Control Loop (Wooldridge, 2000. La discussione vuole rilevare le peculiarità dei vari approcci alla teoria in oggetto, individuare i nodi concettuali comuni ma anche le specificità di ciascun apporto. Concludo quindi con alcune osservazioni di carattere epistemologico sui vantaggi di un approccio plurale.

Comprare un libro o un e-book è una scelta che i lettori oggi si trovano a fare quotidianamente: la diffusione degli e-book reader a prezzi accessibili e la proposta sempre più varia dei piccoli e grandi editori sta cambiando la percezione del valore commerciale dell'oggetto libro e del valore attribuito dal consumatore finale al lavoro di intermediazione delle case editrici e della distribuzione. Sorgono sistemi "alternativi" di condivisione dei testi digitali, che sfruttano la rete Internet, celebrati come democratici o demonizzati come pirateria illegale, ma sicuramente rispondenti a quello che è il cambio di prospettiva, di percezione, di abitudini di consumo del lettore. Quanto si può parlare, dunque, di pirateria nel mercato degli e-book? E quanto, invece, è importante che l'industria editoriale tenga in considerazione la risposta del consumatore? La presente ricerca si è posta l’obiettivo di svolgere una indagine esplorativa su questi temi, che stanno assumendo un rilievo sempre maggiore all’interno dell’opinione pubblica, e che sono destinati in futuro ad incidere in modo sempre più diretto sull’evoluzione economica e professionale dell’intero settore editoriale. L’indagine ha visto, in questa prima fase, l’utilizzo di un questionario diffuso online sui social network, in siti e forum dedicati alla lettura, attraverso mailing list di gruppi di interesse, con il primo obiettivo di precisare il profilo di quell’avanguardia di lettori forti e che si muovono agilmente tra il cartaceo e il digitale, raccogliere informazioni rispetto alle loro abitudini di ricerca di nuove letture e descriverne le dinamiche di matchmaking preliminari all’acquisto.

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

    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.

    Due to their structural similarity, interleukin (IL)-19, IL-20, IL-22, IL-24 and IL-26 were combined with IL-10 in the so-called IL-10 family. To expand the knowledge on IL-19, IL-20 and IL-24, we systematically and quantitatively analysed the expression of these mediators and their receptor chains in vitro and in vivo under various conditions and in comparison with other IL-10 family members. In vitro, IL-19, IL-20 and IL-24 were produced not only by activated immune cells, particularly monocytes, but also to a similar extent by keratinocytes. IL-1beta increased the expression of these mediators 1000-fold (IL-19) and 10-fold (IL-20 and IL-24) in keratinocytes. In vivo, these cytokines were expressed preferentially in inflamed tissues. The absence of either R1 chain for the two types of receptor complexes for these cytokines (IL-20R1/IL-20R2 and IL-22R1/IL-20R2) on immune cells implies that they cannot act on these cells. In fact, IL-19, IL-20 and IL-24 did not induce activation of signal transducer and activator of transcription (STAT) molecules in immune cells. Instead, several tissues, particularly the skin, tissues from the reproductive and respiratory systems, and various glands appeared to be the main targets of these mediators. Keratinocytes expressed both receptor complexes; however, the expression of IL-22R1 was 10 times higher than that of IL-20R1. Interferon-gamma further increased the expression of IL-22R1 and decreased that of IL-20R1, suggesting that under T1 cytokine conditions these mediators primarily affect keratinocytes via the IL-22R1/IL-20R2 complex. In summary, these data support the notion that IL-19, IL-20 and IL-24 are distinct from classical ILs and constitute a separate subfamily of mediators within the IL-10 family.

Similarly, flaky tail (a/a ma ft/ma ft/J mice were described as a model for IV, and shown to be predisposed to eczema. The aim of this study was to correlate the flaky tail mouse phenotype with human IV and AD, in order to dissect early molecular events leading to atopic dermatitis in mice and men, suffering from filaggrin deficiency. Thus, 5-days old flaky tail pups were analyzed histologically, expression of cytokines was measured in skin and signaling pathways were investigated by protein analysis. Human biopsies of IV and AD patients were analyzed histologically and by real time PCR assays. Our data show acanthosis and hyperproliferation in flaky tail epidermis, associated with increased IL1β and thymic stromal lymphopoietin (TSLP expression, and Th2-polarization. Consequently, NFκB and Stat pathways were activated, and IL6 mRNA levels were increased. Further, quantitative analysis of late epidermal differentiation markers revealed increased Small proline-rich protein 2A (Sprr2a synthesis. Th2-polarization and Sprr2a increase may result from high TSLP expression, as shown after analysis of 5-days old K14-TSLP tg mouse skin biopsies. Our findings in the flaky tail mouse correlate with data obtained from patient biopsies of AD, but not IV. We propose that proinflammatory cytokines are responsible for acanthosis in flaky tail epidermis, and together with the Th2-derived cytokines lead to morphological changes. Accordingly, the a/a ma ft/ma ft/J mouse model can be used as an appropriate model to study early AD onset associated with profilaggrin deficiency.

Inward investment is accelerating, as foreign firms seek a foothold in the potentially lucrative Chinese market. And domestic consolidation is heating up among the country's fragmented industries due to overcapacity. Now that the Chinese government plans to address policy hurdles affecting M&A and relax foreign currency controls, activity levels should rise across most sectors. But while this may improve market positions and increase synergies for local and foreign investors, credit risks could intensify.

Alcuni mesi fa, tuttavia, Nadine Gordimer veniva ricordata dai giornali per un’impresa non letteraria: si tratta di un film-documentario dal titolo Johannesburg-Berlin, The Wall in the Mind, che Gordimer ha scritto e che ha girato con suo figlio, Hugo Cassirer, nel 1995-1996.

    Full Text Available La questione centrale da cui si sviluppa l’intero articolo è dimostrare come ascoltare la voce dell’altro e riconoscerne l’identità costituisce il compito più importante che la società odierna ci chiede di svolgere. Tuttavia, ascoltare l’altro che parla di noi e del nostro universo culturale è un’impresa complessa e difficile, ma, al tempo stesso, una grande opportunità interculturale. L’identità personale dell’individuo è un concetto complesso e multi-sfaccettato, il suo percorso di costruzione dipende da molteplici fattori. Il legame con il luogo d’appartenenza gioca sicuramente un ruolo molto importante, così come altrettanto significativo è il confronto con l’altro da me attraverso il quale scaturisce una più chiara definizione e consapevolezza di noi stessi. Questo confronto sicuramente avviene attraverso la narrazione e si spinge ancora oltre se l’altro non si limita a raccontare il suo mondo, ma inizia a parlare del nostro, ossia di una società che inizialmente non gli appartiene ma nella quale si trova a vivere. Così facendo, l’altro, ai suoi occhi, siamo noi.        MY WORLD FROM THE OUTSIDE: AN INTERCULTURAL OPPORTUNITY   The main issue dealt with in this article is to demonstrate how listening to the voice of the other and recognizing identity is the most important task which current society asks of us.  Yet listening to others who talk about us and our cultural universe is complex and difficult, although it offers a great intercultural opportunity. An individual’s personal identity is a complex, multi-faceted concept and its creation depends on many factors.  The link to one’s place of origin undoubtedly plays an important role, and comparison with those who differ from me triggers a clearer definition and awareness of ourselves in a meaningful way.  This comparison takes place through narration and goes beyond, if the speaker does not merely limit him or herself to telling about their

  17. Il desiderio stellare del Principe di Salina

    Full Text Available If desire originates from the stars –de sideribus- and, if we agree with this etymology, the Subject’s desire coincides with the Other’s desire, Tomasi di Lampedusa’s Il Gattopardo shows one of the most fascinating and enigmatic literary figures of stellar desire, as it can be read, furthermore, in the explicit of the seventh part of the novel: «Giunta faccia a faccia con lui sollevò il velo e così, pudica ma pronto ad esser posseduta, gli apparve più bella di come mai l’avesse intravista negli spazi stellari».            Why does this female figure descending from the stellar spaces in order to yield to Don Fabrizio who has reached the final stage of his journey, embody the object of a possessive desire which, paradoxically, corresponds to death? Indeed, death marks the entire novel since its memorable incipit: «”Nunc et in hora mortis nostrae. Amen”». What kind of desire is it precisely about? What is our unexpectedly Hamlet-like hero troubled by? The cues which the novel shows for the interpretation of this desire are few but meaningful. However we could appeal to Ricordi d’Infanzia which lead to the writer’s laboratory at the time of the Gattopardo, and, perhaps, let us know the “cause” of the prince of Salina’s desire.

    Full Text Available Il tema dell’articolo verte sulle trasformazioni urbane e territoriali generate dai grandi eventi in Spagna in relazione all’implementazione/trasformazione dei sistemi di trasporto durante gli stessi. A tale scopo l’articolo analizza i risultati, sia finali che attesi, delle trasformazioni degli ultimi 15 anni in Spagna in occasione di questi eventi straordinari. Nello specifico si analizzano cinque casi-studio: Barcellona ed i Giochi Olimpici del 1992, Siviglia e l’Esposizione Universale del 1992, Bilbao e la realizzazione del Museo Guggenheim (landmark architettonico nel 1997, Valencia e la Coppa America del 2007 e infine Saragozza e l’Expo del 2008 dove è stata realizzata una nuova stazione dell’Alta Velocità. Le occasioni, colte al volo dalle città spagnole, hanno modificato il volto dell’intero paese e negli ultimi quindici anni la Spagna si è dotata non solo di un nuovo grande patrimonio architettonico e di nuovi modelli di città, ma principalmente si è dotata di un sistema di trasporto (aeroporti, porti, metropolitane e strade moderno ed efficiente.

  19. Interleukin-6 (IL-6) production by astrocytes: autocrine regulation by IL-6 and the soluble IL-6 receptor.

    Science.gov (United States)

    Van Wagoner, N J; Oh, J W; Repovic, P; Benveniste, E N

    1999-07-01

    In the CNS, astrocytes are a major inducible source of interleukin-6 (IL-6). Although IL-6 has beneficial effects in the CNS because of its neurotrophic properties, its overexpression is generally detrimental, adding to the pathophysiology associated with CNS disorders. Many factors have been shown to induce IL-6 expression by astrocytes, particularly the cytokines tumor necrosis factor-alpha (TNF-alpha) and interleukin-1 beta (IL-1beta). However, the role of IL-6 in its own regulation in astrocytes has not been determined. In this study, we examined the influence of IL-6 alone or in combination with TNF-alpha or IL-1beta on IL-6 expression. IL-6 alone had no effect on IL-6 expression; however, the addition of the soluble IL-6 receptor (sIL-6R) induced IL-6 transcripts. Addition of TNF-alpha or IL-1beta plus IL-6/sIL-6R led to synergistic increases in IL-6 expression. This synergy also occurred in the absence of exogenously added IL-6, attributable to TNF-alpha- or IL-1beta-induced endogenous IL-6 protein production. IL-6 upregulation seen in the presence of TNF-alpha or IL-1beta plus IL-6/sIL-6R was transcriptional, based on nuclear run-on analysis. Experiments were extended to other IL-6 family members to determine their role in IL-6 regulation in astrocytes. Oncostatin M (OSM) induced IL-6 alone and synergized with TNF-alpha for enhanced expression. These results demonstrate that IL-6/sIL-6R and OSM play an important role in the regulation of IL-6 expression within the CNS, particularly in conjunction with the proinflammatory cytokines TNF-alpha and IL-1beta.

    Streptococcus mutans is important in dental caries. Although the role of cytokines in the pathogenesis of dental caries is not clear, components of S. mutans were found to stimulate production of pro-inflammatory cytokines. We examined the associations of interleukin (IL)-1β, IL-1 receptor antagonist (IL-1ra), and IL-10 with dental caries. Unstimulated whole saliva and blood samples were obtained from 108 children aged 6-12 years with high caries (decayed, missing, or filled teeth [dmft/DMFT] index >4, n = 37), moderate caries (dmft/DMFT = 1-4, n = 37), or caries-free (dmft/DMFT = 0, n = 34). S. mutans level was classified as low (caries was not correlated with salivary or serum concentrations of the studied cytokines. S. mutans level positively correlated with saliva IL-1β concentration and inversely correlated with saliva IL-1ra concentration. There was no correlation of IL-1β, IL-1ra, or IL-10 gene polymorphisms with dental caries. S. mutans is important in stimulating saliva IL-1β and inhibiting IL-1ra. Future studies of associations between cytokines and dental caries should investigate additional cytokines and enroll a larger number of participants.

    The share of female teachers in the U.S. with an MA more than doubled between 1970 and 2000.

  20. Vaccines against stimulants: cocaine and MA.

    2014-02-01

    While the worldwide prevalence of cocaine use remains significant, medications, or small molecule approaches, to treat drug addictions have met with limited success. Anti-addiction vaccines, on the other hand, have demonstrated great potential for treating drug abuse using a distinctly different mechanism of eliciting an antibody response that blocks the pharmacological effects of drugs. We provide a review of vaccine-based approaches to treating stimulant addictions; specifically and cocaine addictions. This selective review article focuses on the one cocaine vaccine that has been into clinical trials and presents new data related to pre-clinical development of a methamphetamine (MA) vaccine. We also review the mechanism of action for vaccine induced antibodies to abused drugs, which involves kinetic slowing of brain entry as well as simple blocking properties. We present pre-clinical innovations for MA vaccines including hapten design, linkage to carrier proteins and new adjuvants beyond alum. We provide some new information on hapten structures and linkers and variations in protein carriers. We consider a carrier, outer membrance polysaccharide coat protein (OMPC), that provides some self-adjuvant through lipopolysaccharide components and provide new results with a monophosopholipid adjuvant for the more standard carrier proteins with cocaine and MA. The review then covers the clinical trials with the cocaine vaccine TA-CD. The clinical prospects for advances in this field over the next few years include a multi-site cocaine vaccine clinical trial to be reported in 2013 and phase 1 clinical trials of a MA vaccine in 2014.

    Butterworth, N. P.; Quevedo, L. E.; Müller, R. D.

    2011-12-01

    We apply a novel workflow utilising the BEM-Earth geodynamic software to analyse the global coupled plate-mantle dynamics at 50 Ma. A subduction history model based on kinematic data going as far back as 80 Ma was developed using the GPlates software. Advection of the plates into the mantle takes into account the absolute plate motions and lithospheric thickness derived from its age to produce an estimated density heterogeneity initial model condition in the upper mantle. The resulting global model consists of regions of a mantle viscosity and density structure that is post-processed to ensure smooth non-overlapping 3D surfaces. BEM-Earth is then free to evolve the model toward the 50 Ma solution. The evolution of the model is driven by self-consistent buoyancy driven mantle dynamics. We use the model velocity output to quantify changes in forces driving the plates before and after 50 Ma. We analyse the rapid change in plate motion of India, Africa and plates in the Pacific Ocean basin by considering slab-pull, ridge-push and mantle drag/suction forces that naturally result from such top-down driven mantle flow. We compare the results with plate kinematic reconstructions and other geological observations.

    Directory of Open Access Journals (Sweden)

    Clive Bell

    2010-12-01

    Full Text Available Clive Bell (1881-1964, critico d’arte inglese appartenente al Gruppo di Bloomsbury, fu tra i fautori più decisi del formalismo in estetica. In questo articolo critica qui con ironica asprezza, la concezione dell’arte espressa da Freud in un noto passo dell’Introduzione alla Psicoanalisi, in cui l’artista viene descritto come una persona insoddisfatta che compensa attraverso l’arte i suoi bisogni pulsionali. Secondo Clive Bell il piacere dell’arte non nasce dall’appagamento di desiderio ma da una speciale emozione che riguarda solo la “Forma Significante”. “L’artista– scrive – non è alle prese… con la “sublimazione” delle sue normali brame, perché è alle prese con un problema totalmente al di fuori dell’esperienza normale. Il suo obbiettivo è creare una forma che debba corrispondere a un’idea estetica, non creare una forma che debba soddisfare le voglie inappagate del dottor Freud.” Conclude poi dicendo: “A me pare che il dottor Freud possa essere un eccellente psicoanalista; ma l’arte, sono certo, farebbe meglio a lasciarla stare.”

    L’astronomia a Roma c’è sempre stata, ma un po’ nascosta: era nei palazzi, nelle chiese o, meglio, sopra le chiese, specole disseminate lungo un percorso che oramai conoscono in pochi. I romani hanno assistito, incuriositi ed impauriti, al rogo di Giordano Bruno in un angolo di Campo de' Fiori a loro familiare, ma probabilmente non capirono bene di quale colpa fosse accusato. Non pensarono certo che si trattasse di un filosofo e di uno scienziato che aveva cercato di immaginare in che modo era fatto il mondo. Chi era questo Galileo, di cui si celebrava il processo a S. Maria sopra Minerva? Era un uomo che voleva cambiare la prospettiva del mondo e che, per questo, era stato ammonito da Roberto Bellarmino. E chi era questo gesuita, Secchi, che nel 1870 costringeva gli Italiani a privare Roma del suo Osservatorio Astronomico, visto che il Direttore non riconosceva lo Stato Italiano? Come è possibile che dopo la visita di Hitler a Mussolini alla vigilia della Guerra, la Germania decise di regalare all’...

    Previous studies indicated that methyl jasmonate (MeJA) treatment could effectively reduce the chilling injury of many fruits, including banana, but the underlying mechanism is poorly understood. In this study, one lateral organ boundaries (LOB) domain (LBD) gene, designated as MaLBD5, was isolated and characterized from banana fruit. Expression analysis revealed that accumulation of MaLBD5 was induced by cold temperature and MeJA treatment. Subcellular localization and transactivation assays showed that MaLBD5 was localized to the nucleus and possessed transcriptional activation activity. Protein-protein interaction analysis demonstrated that MaLBD5 physically interacted with MaJAZ1, a potential repressor of jasmonate signaling. Furthermore, transient expression assays indicated that MaLBD5 transactivated a jasmonate biosynthesis gene, termed MaAOC2, which was also induced by cold and MeJA. More interestingly, MaJAZ1 attenuated the MaLBD5-mediated transactivation of MaAOC2. These results suggest that MaLBD5 and MaJAZ1 might act antagonistically in relation to MeJA-induced cold tolerance of banana fruit, at least partially via affecting jasmonate biosynthesis. Collectively, our findings expand the knowledge of the transcriptional regulatory network of MeJA-mediated cold tolerance of banana fruit.

    Full Text Available Il desiderio del poeta Gabriele d’Annunzio di rinnovare la sua casa natale in Pescara con un intervento di ‘re - styling’, fu affrontato nel 1921 dal cognato l’ingegnere Antonino Liberi, progettista di numerose opere. Perl’antica casa, bisognosa di interventi di manutenzione straordinaria alquanto urgenti, l’ingegnere propose una serie di modifiche interne utili a migliorare la vivibilità degli ambienti, ma anche due soluzioni di facciata che ne avrebbero modificato radicalmente l’aspetto. Il presente saggio intende affrontare, più che gli interventi programmati sulla casa, il modo di comunicare il progetto di restauro dell’ingegnere Liberi, considerando la grafica, le scale delle rappresentazioni, il metodo progettuale.

    Full Text Available Il gioco non viene distrutto da colui che bara, ma da chi denuncia l’assurdità delle regole e la loro natura puramente convenzionale. Un’inedita lettura del Nipote di Rameau di Diderot mette in evidenza il gioco della pantomima quale sinonimo di sottomissione alle regole sociali e prima ancora ai bisogni. È il modo di stare in società, di conquistare un ruolo, tanto più falso quanto più lo sforzo della mimica ha il suo effetto. Prendere posizione non significa affatto affermare se stessi, le proprie idee; è adeguarsi ai bisogni e alle necessità di una società che rende schiavi. Rameau è un abilissimo giocatore, il migliore fino a quando non decide di mettere in ridicolo le regole del gioco che sta interpretando e chi le ha inventate: i nuovi borghesi.

    Previous studies have shown the involvement of the immune response in the progression of human uterine cervix cancer. The aim of this study was to determine the expression of Interleukin-2 (IL-2), IL-2 receptor (IL-2R) and Interleukin 10 (IL-10) in different grades of cervical intraepithelial neoplasias of the exocervix (CIN 1, 2 and 3), and its relationship with the serum cytokine profiles and human papilomavirus (HPV) infection status. Indirect immunofluorescence was used to study the expression of IL-2, IL-2R and IL-10 in human cervical samples from 50 patients and 9 normal controls. Serum IL-2, IL-2R and IL-10 were measured by ELISA and HPV DNA and HPV types were identified by PCR. Increased number of IL-2, IL-2R and IL-10 positive cells were observed in the cervix from patients with CIN, associated with the grades of dysplasia. A significant correlation was observed between IL-2 and IL-2R (p>0.0001), IL-2 and IL-10 (p>0.0001), as well as IL-10 and IL-2R (p>0.0001). Twenty percent of patients were HPV positive and 84% of those patients were tissue cytokine positive. These results suggest that IL-2, IL-2R and IL-10 tissue expression may play a role in the development of cervical intraepithelial dysplasias.

    The Safety and Mission Assurance (S&MA) Directorate is responsible for mitigating risk, providing system safety, and lowering risk for space programs from ground to space. The S&MA is divided into 4 divisions: The Space Exploration Division (NC), the International Space Station Division (NE), the Safety & Test Operations Division (NS), and the Quality and Flight Equipment Division (NT). The interns, myself and Arun Aruljothi, will be working with the Risk & Reliability Analysis Branch under the NC Division's. The mission of this division is to identify, characterize, diminish, and communicate risk by implementing an efficient and effective assurance model. The team utilizes Reliability and Maintainability (R&M) and Probabilistic Risk Assessment (PRA) to ensure decisions concerning risks are informed, vehicles are safe and reliable, and program/project requirements are realistic and realized. This project pertains to the Orion mission, so it is geared toward a long duration Human Space Flight Program(s). For space missions, payload is a critical concept; balancing what hardware can be replaced by components verse by Orbital Replacement Units (ORU) or subassemblies is key. For this effort a database was created that combines mass and reliability data, called Mass and Reliability System or MaRS. The U.S. International Space Station (ISS) components are used as reference parts in the MaRS database. Using ISS components as a platform is beneficial because of the historical context and the environment similarities to a space flight mission. MaRS uses a combination of systems: International Space Station PART for failure data, Vehicle Master Database (VMDB) for ORU & components, Maintenance & Analysis Data Set (MADS) for operation hours and other pertinent data, & Hardware History Retrieval System (HHRS) for unit weights. MaRS is populated using a Visual Basic Application. Once populated, the excel spreadsheet is comprised of information on ISS components including

    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

    While the worldwide prevalence of cocaine use remains significant, medications, or small molecule approaches, to treat drug addictions have met with limited success. Anti-addiction vaccines, on the other hand, have demonstrated great potential for treating drug abuse using a distinctly different mechanism of eliciting an antibody response that blocks the pharmacological effects of drugs. We provide a review of vaccine-based approaches to treating stimulant addictions; specifically and cocaine addictions. This selective review article focuses on the one cocaine vaccine that has been into clinical trials and presents new data related to pre-clinical development of a methamphetamine (MA) vaccine. We also review the mechanism of action for vaccine induced antibodies to abused drugs, which involves kinetic slowing of brain entry as well as simple blocking properties. We present pre-clinical innovations for MA vaccines including hapten design, linkage to carrier proteins and new adjuvants beyond alum. We provide some new information on hapten structures and linkers and variations in protein carriers. We consider a carrier, outer membrance polysaccharide coat protein (OMPC), that provides some self-adjuvant through lipopolysaccharide components and provide new results with a monophosopholipid adjuvant for the more standard carrier proteins with cocaine and MA. The review then covers the clinical trials with the cocaine vaccine TA-CD. The clinical prospects for advances in this field over the next few years include a multi-site cocaine vaccine clinical trial to be reported in 2013 and phase 1 clinical trials of a MA vaccine in 2014.

    Full Text Available A substantial body of accounting and finance literature has been devoted to the study of Mergers and Acquisitions (M&As dominated by discussions relating to the gains and losses that accrue from transactions involving large public companies. This paper makes a unique contribution to the literature by investigating the M&A experience of microcap businesses. Transactions involving microcap M&A are substantially different to those involving large companies on a number of dimensions. This paper explores the determinants of microcap M&A success and pitfalls and problems from an integration perspective. Due to the paucity of research in the area an exploratory research design is employed, conducting interviews with five CEOs of companies that had each managed multiple transactions. We find microcap M&As are successful when measured against identified goals but generally take longer and cost more than expected. Further, culture and communication are key issues in determining success/failure. We also find the in-house management of integration aspects is problematic for these businesses and suggest this warrants further study.

    Background IL-9 has been suggested to play an important role in chronic inflammation due to its effect on remodeling and cell recruitment. Since basophils can be found in inflamed tissue, we wanted to test if human basophils are capable of secreting IL-9 under the influence of growth or tissue...... factors like IL-3 or IL-33, respectively. Methods Basophils, purified from buffy coat blood by negative selection (purity > 95%), were cultured for 24 hours in RPMI culture medium (1x106 cells/ml) supplemented with 5% human serum, and IL-3 (10 ng/ml) and/or IL-33 (50 ng/ml). The cells were then analysed...... by FACS for ST2 expression where basophils were gated as FceRIa+CD3-CD14-CD19-CD56-. The supernatant was tested for IL-9 using a multiplex magnetic bead assay. Results Human basophils have recently been described to express the IL-33 receptor ST2. In agreement with previous findings, our results showed...

    Full Text Available Tra le righe di uno scritto, attraverso le rappresentazioni e le interpretazioni, è possibile ritrovare schegge di un originale smarrito, ma non si può ricostruire oggettivamente e interamente la vita veramente vissuta. La scelta sintagmatica e paradigmatica, consapevole e/o inconsapevole, nasce infatti da un’impalcatura, da schemi mentali con cui l’uomo convive da sempre. Una storia e una frase dicono molto di più di quel che dicono. La densità di significazione e tutti i mondi che ci sono dietro ad alcuni sostantivi, verbi, avverbi, aggettivi restano il più delle volte un segreto. Il punto di vista narrativo si pone, dunque, come potenziale chiave euristica ed ermeneutica in grado di esplorare e recuperare patrimoni di esperienze di vita dei soggetti. La scrittura consente al soggetto di raccontarsi e di raccontare un io nascosto e rappresenta un tentativo di strapparsi quella ‘maschera di ferro’ che nasconde le emozioni, di andare ‘oltre la soglia’, di dare sfogo ad un’identità più o meno autentica, di comprendere orientamenti e percorsi di senso. Essa è l’esito di chi narra che, uscito dalla polarità dello schema lineare della vita, affianca se stesso in modo tale da avere uno sguardo sul sistema di insieme di cui è parte.

    Radon was discovered in 1900, but its potential dangerousness for man was fully understood only in 1950. Being a radioactive natural gas - and therefore particularly dangerous - radon results from the long decay chain of radionuclides, such as thorium and radium. Some igneous rocks (granite, tufa and lava) as well as coal are considered to be the main sources of this radionuclide. A number of epidemiologic studies have shown the carcinogenicity of this element, particularly among miners and workers subjected to high level exposure in confined spaces such as basements, garages, cellars, etc. There are, however, some techniques to remove radon in order to reduce exposure to minimum values. [Italian] Il radon fu scoperto nel 1900, ma solo nel 1950 si comprese la sua potenziale pericolosita' per l'uomo. Il radon e' particolarmente pericoloso essendo un gas naturale radioattivo. Esso proviene dalla lunga catena di decadimento di radionuclidi come il torio e di radio. Sorgenti di tale radionuclide sono da considerarsi principalmente alcune rocce ignee (graniti, tufi e lave) e il carbone. Diversi studi epidemiologici hanno evidenziato la cancerogenicita' di tale elemento, specie tra i minatori e soggetti esposti ad alti livelli in ambienti confinati quali scantinati, garage sotterranei, ecc.. Esistono comunque tecniche di intervento per la rimozione del gas radon in modo tale da ridurre l'esposizione a valori minimi.

    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

    Different galaxy formation processes leave different imprints on the gas and stellar kinematic patterns for a galaxy. With MaNGA, we now have after one year of observations an unprecedented sample of 1400 nearby galaxies for which we can study gas and stellar kinematics in much detail, based on integral-field spectroscopy. We are measuring kinematic quantities such as LambdaR (angular momentum) and their (possible) correlations with other galaxy properties such as mass, morphology and environment. By quantifying the kinematic (sub)structures in velocity and dispersion maps, we will construct a kinematic galaxy classification that can be linked to their formation processes.

    Full Text Available Despite the substantial advances made in cross-Strait relations during Ma Ying-jeou’s (Ma Yingjiu first term, the ROC president’s rhetoric varied considerably as he grappled with the difficult reality of implementing campaign and inauguration pledges to establish better relations with China while striving to maintain national respect and sovereignty. In this article, we put forward a framework for measuring, analysing and explaining this variation in President Ma’s first-term discourse. Analysing a very large number of Ma’s speeches, addresses, etc., we provide empirical assessments of how the content of Ma’s public pronouncements has developed over time, how his rhetoric varies according to the strategic context and timing of a speech, and how his discourse compares to that of his predecessor, Chen Shui-bian (Chen Shuibian. In addressing these questions, the article contributes a quantitative perspective to existing work on political discourse in Taiwan and to the growing methodological and applied literature on how to systematically analyse Chinese political text.

    The 6-year SDSS-IV MaNGA survey will measure spatially resolved spectroscopy for 10,000 nearby galaxies using the Sloan 2.5m telescope and the BOSS spectrographs with a new fiber arrangement consisting of 17 individually deployable IFUs. We present the simultaneous design of the target selection and IFU size distribution to optimally meet our targeting requirements. The requirements for the main samples were to use simple cuts in redshift and magnitude to produce an approximately flat number density of targets as a function of stellar mass, ranging from 1x109 to 1x1011 M⊙, and radial coverage to either 1.5 (Primary sample) or 2.5 (Secondary sample) effective radii, while maximizing S/N and spatial resolution. In addition we constructed a "Color-Enhanced" sample where we required 25% of the targets to have an approximately flat number density in the color and mass plane. We show how these requirements are met using simple absolute magnitude (and color) dependent redshift cuts applied to an extended version of the NASA Sloan Atlas (NSA), how this determines the distribution of IFU sizes and the resulting properties of the MaNGA sample.

    Los Alamos National Laboratory’s proposed MaRIE facility is slated to introduce the world’s highest energy hard x-ray free electron laser (XFEL). As the light source for the Matter-Radiation Interactions in Extremes experimental facility (MaRIE), the 42-keV XFEL, with bursts of x-ray pulses at gigahertz repetition for studying fast dynamical processes, will help accelerate discovery and design of the advanced materials needed to meet 21st-century national security and energy security challenges. Yet the science of free-electron lasers has a long and distinguished history at Los Alamos National Laboratory (LANL), where for nearly four decades Los Alamos scientists have been performing research, design, development, and collaboration work in FEL science. The work at Los Alamos has evolved from low-gain amplifier and oscillator FEL development to highbrightness photoinjector development, and later, self-amplified spontaneous emission (SASE) and high-gain amplifier FEL development.

    IL-23/IL-17-induced neutrophil recruitment plays a pivotal role in rheumatoid arthritis (RA). However, the mechanism of the neutrophil recruitment is obscure. Here we report that prostaglandin enhances the IL-23/IL-17-induced neutrophil migration in a murine model of RA by inhibiting IL-12 and IFN γ production. Methylated BSA (mBSA) and IL-23-induced neutrophil migration was inhibited by anti-IL-23 and anti-IL-17 antibodies, COX inhibitors, IL-12, or IFNγ but was enhanced by prostaglandin E2 (PGE2). IL-23-induced IL-17 production was increased by PGE2 and suppressed by COX-inhibition or IL-12. Furthermore, COX inhibition failed to reduce IL-23-induced neutrophil migration in IL-12- or IFNγ-deficient mice. IL-17-induced neutrophil migration was not affected by COX inhibitors, IL-12, or IFNγ but was inhibited by MK886 (a leukotriene synthesis inhibitor), anti-TNFα, anti-CXCL1, and anti-CXCL5 antibodies and by repertaxin (a CXCR1/2 antagonist). These treatments all inhibited mBSA- or IL-23-induced neutrophil migration. IL-17 induced neutrophil chemotaxis through a CXC chemokines-dependent pathway. Our results suggest that prostaglandin plays an important role in IL-23-induced neutrophil migration in arthritis by enhancing IL-17 synthesis and by inhibiting IL-12 and IFNγ production. We thus provide a mechanism for the pathogenic role of the IL-23/IL-17 axis in RA and also suggest an additional mechanism of action for nonsteroidal anti-inflammatory drugs. PMID:19289819

    Schizophrenia has been associated with a large range of autoimmune diseases, with a history of any autoimmune disease being associated with a 45% increase in risk for the illness. The inflammatory system may trigger or modulate the course of schizophrenia through complex mechanisms influencing neurodevelopment, neuroplasticity and neurotransmission. In particular, increases or imbalance in cytokine before birth or during the early stages of life may affect neurodevelopment and produce vulnerability to the disease. A total of 27 polymorphisms of IL1N gene: rs1800587, rs17561; IL1B gene: rs1143634, rs1143643, rs16944, rs4848306, rs1143623, rs1143633, rs1143627; IL1RN gene: rs419598, rs315952, rs9005, rs4251961; IL6 gene: rs1800795, rs1800797; IL6R gene: rs4537545, rs4845617, rs2228145, IL10 gene: rs1800896, rs1800871, rs1800872, rs1800890, rs6676671; IL10RA gene: rs2229113, rs3135932; TGF1B gene: rs1800469, rs1800470; each selected on the basis of molecular evidence for functionality, were investigated in this study. Analysis was performed on a group of 621 patients with diagnosis of schizophrenia and 531 healthy controls in Polish population. An association of rs4848306 in IL1B gene, rs4251961 in IL1RN gene, rs2228145 and rs4537545 in IL6R with schizophrenia have been observed. rs6676671 in IL10 was associated with early age of onset. Strong linkage disequilibrium was observed between analyzed polymorphisms in each gene, except of IL10RA. We observed that haplotypes composed of rs4537545 and rs2228145 in IL6R gene were associated with schizophrenia. Analyses with family history of schizophrenia, other psychiatric disorders and alcohol abuse/dependence did not show any positive findings. Further studies on larger groups along with correlation with circulating protein levels are needed.

Oggi c’è una povertà di relazioni umane, c’è una perdita di linguaggio: accade quindi che le singolarità si spengono. Ma ognuno di noi ha una singolarità parlante, che ha bisogno di essere ascoltata. È un bisogno simbolico prima che psicologico. E questo spiega la necessità di spazi dove la propria storia di vita sia ascoltata, perché nel nostro presente ci sia tanto interesse per il biografico C’è la necessità di pratiche che aiutano a cercare forme di vita che siano più vive e più desiderabili. C’è la necessità di contesti dove sperimentare un percorso che cerchi le parole per dirsi, per cercare un legame soggettivo tra sé e ciò che si dice, si scrive, in un percorso di comunicazione, di auto-conoscenza, di comprensione.

    The interleukin (IL)-12 family, composed of heterodimeric cytokines including IL-12 (formed by IL-12p35 and IL-12p40 subunits), IL-23 (formed by IL-23p19 and IL-12p40 subunits), IL-27 (formed by IL-27p28 and EBI3 subunits) and IL-35 (formed by IL-12p35 and EBI3 subunits), establishes a link between innate and adaptive immunity that involves different immune effector cells and cytokines to tumors. However, the role of IL-12 family in breast cancer (BC) progression and prognosis remains unclear. In the present study, we demonstrated evidence indicating that EBI3, IL-12p35 and IL-12p40 but not IL-23p19 or IL-27p28 were highly expressed in BC tissues, suggested that tumor derived EBI3, IL-12p35 and IL-12p40 were associated with tumor progression. Circulating IL-12 and IL-23 low expressed, but IL-27 and IL-35 high expressed in BC patients, especially circulating IL-23 associated with IL-35 to mediate BC tumor resection. Ki-67, p53 and EGFR expression on BC tissues, as well as CA125, CA153 and CA199 levels on BC bloods increased when circulating IL-23: IL-35 ratio decreased. Together, for the first time, our data suggest that circulating IL-23: IL-35 ratio may be an important indicator association with BC progression and prognosis. However, further research should be carried out to assess the implications of circulating IL-23: IL-35 ratio in a larger sample size.

    Highlights: • Seven NuMA isoforms generated by alternative splicing were categorized into 3 groups: long, middle and short. • Both exons 15 and 16 in long NuMA were “hotspot” for alternative splicing. • Lower expression of short NuMA was observed in cancer cells compared with nonneoplastic controls. • Distinct localization pattern of short isoforms indicated different function from that of long and middle NuMA. - Abstract: The large nuclear mitotic apparatus (NuMA) has been investigated for over 30 years with functions related to the formation and maintenance of mitotic spindle poles during mitosis. However, the existence and functions of NuMA isoforms generated by alternative splicing remains unclear. In the present work, we show that at least seven NuMA isoforms (categorized into long, middle and short groups) generated by alternative splicing from a common NuMA mRNA precursor were discovered in HeLa cells and these isoforms differ mainly at the carboxyl terminus and the coiled-coil domains. Two “hotspot” exons with molecular mass of 3366-nt and 42-nt tend to be spliced during alternative splicing in long and middle groups. Furthermore, full-length coding sequences of long and middle NuMA obtained by using fusion PCR were constructed into GFP-tagged vector to illustrate their cellular localization. Long NuMA mainly localized in the nucleus with absence from nucleoli during interphase and translocated to the spindle poles in mitosis. Middle NuMA displayed the similar cell cycle-dependent distribution pattern as long NuMA. However, expression of NuMA short isoforms revealed a distinct subcellular localization. Short NuMA were present in the cytosol during the whole cycle, without colocalization with mitotic apparatus. These results have allowed us tentatively to explore a new research direction for NuMA’s various functions.

  3. Gondwanaland from 650-500 Ma assembly through 320 Ma merger in Pangea to 185-100 Ma breakup: supercontinental tectonics via stratigraphy and radiometric dating

    Gondwanaland lasted from the 650-500 Ma (late Neoproterozoic-Cambrian) amalgamation of African and South American terranes to Antarctica-Australia-India through 320 Ma (mid-Carboniferous) merging with Laurussia in Pangea to breakup from 185 to 100 Ma (Jurassic and Early Cretaceous). Gondwanaland straddled the equator at 540 Ma, lay wholly in the Southern Hemisphere by 350 Ma, and then rotated clockwise so that at 250 Ma Australia reached the S pole and Africa the equator. By initial breakup of Pangea at 185 Ma, Gondwanaland had moved northward such that North Africa reached 35°N. The first clear picture of Gondwanaland, in the Cambrian, shows the assembly of continents with later Laurentian, European and Asian terranes along the "northern" margin, and with a trench along the "western" and "southern" margins, reflected by a 10,000-km-long chain of 530-500 Ma granites. The interior was crossed by the Prydz-Leeuwin and Mozambique Orogenic Belts. The shoreline lapped the flanks of uplifts generated during this complex terminal Pan-Gondwanaland (650-500 Ma) deformation, which endowed Gondwanaland with a thick, buoyant crust and lithosphere and a nonmarine siliciclastic facies. During the Ordovician, terranes drifted from Africa as the first of many transfers of material to the "northern" continents. Central Australia was crossed by the sea, and the eastern margin and ocean floor were flooded by grains of quartz (and 600-500 Ma zircon) from Antarctica. Ice centres in North Africa and southern South America/Africa waxed and waned in the latest Ordovician, Early Silurian, latest Devonian, and Early Carboniferous. In the mid-Carboniferous, Laurussia and Gondwanaland merged in the composite called Pangea by definitive right-lateral contact along the Variscan suture, with collisional stress and subsequent uplift felt as far afield as Australia. Ice sheets developed on the tectonic uplands of Gondwanaland south of 30°S. In the Early Permian, the self-induced heat beneath

    2015-12-01

    Interleukin 35 (IL-35) is the most recently identified member of the IL-12 family of cytokines and offers the potential to be a target for new therapies for autoimmune, inflammatory, and infectious diseases. Similar to other members of the IL-12 family including IL-12, IL-23, and IL-27, IL-35 is composed of a heterodimer of α and β chains, which in the case of IL-35 are the p35 and Epstein-Barr virus-induced gene 3 (EBI3) proteins. However, unlike its proinflammatory relatives, IL-35 has immunosuppressive effects that are mediated through regulatory T and B cells. Although there are limited data available regarding the role of IL-35 in human autoimmunity, several murine models of autoimmunity suggest that IL-35 may have potent effects in regulating immunoreactivity via IL-10-dependent mechanisms. We suggest that similar effects are operational in human disease and IL-35-directed therapies hold significant promise. In particular, we emphasize that IL-35 has immunosuppressive ability that are mediated via regulatory T and B cells that are IL-10 dependent. Further, although deletion of IL-35 does not result in spontaneous breach of tolerance, recombinant IL-35 can improve autoimmune responses in several experimental models.

  5. 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.

  8. IL-28 and IL-29: newcomers to the interferon family.

    2007-01-01

    IL-28 and IL-29 were recently described as members of a new cytokine family that shares with type I interferon (IFN) the same Jak/Stat signalling pathway driving expression of a common set of genes. Accordingly, they have been named IFN lambda. IFNs lambda exhibit several common features with type I IFNs: antiviral activity, antiproliferative activity and in vivo antitumour activity. Importantly, however, IFNs lambda bind to a distinct membrane receptor, composed of IFNLR1 and IL10R2. This specific receptor usage suggests that this cytokine family does not merely replicate the type I IFN system and justifies its designation as type III IFN by the nomenclature committee of the International Society of Interferon and Cytokine Research.

    Studies on cytokine levels in Weil's syndrome are lacking. In this study, TNF-α, sTNFR1, IL-6, IL-8 and IL-10 levels were measured in 44 serum samples of patients diagnosed with Leptospira interrogans serovar icterohaemorrhagiae infection. TNF-α levels linked with pulmonary hemorrhagic implications, while elevated sTNFR1 and IL-10 levels linked with fatal cases. IL-6 and IL-8 did not seem to affect the outcome of the disease. Immune response pattern in Weil's syndrome bears resemblance to other patterns described for hemorrhagic fevers. IL-10/TNF-α ratio is proposed as a marker for prognosis.

    Objective:This work aimed to investigate the expression level of lysophosphatidic acid (LPA) and its receptors. The paper also discussed the interrelationship among the LPA, the receptors, and IL-6 and IL-8 in breast cancer tissues. Methods:The ex-pressions of the 3 hypo-types of LPA receptor in the breast cancer and paraneoplastic tissues were detected using semi-quantitative re-verse transcription polymerase chain reaction. The plasma levels of LPA, IL-6 and IL-8 were respectively detected in healthy subjects and in patients with benign breast tumor using the LPA biochemistry and enzyme linked immunosorbent assay kits. Results:The plas-ma LPA level was significantly higher in patients with breast cancer metastasis than in those with local breast cancer (P<0.01), benign breast tumor (P<0.01), and healthy volunteers (P<0.01). In addition, the IL-6 and IL-8 plasma levels were higher in the group with me-tastasis compared with the other three groups, too (P<0.01). LPA1 expression level was higher in breast cancer tissue than in benign breast tumor (P<0.05) and in normal breast tissue (P<0.05). There was a significantly positive correlation between the plasma LPA and the plasma IL-6 in patients with breast cancer (P<0.01), and between the plasma LPA and IL-8 (P<0.01). Conclusion:LPA expressions on the endogenous IL-6 and IL-8 in patients with breast cancer may have an up-regulation. Moreover, the detection of the LPA, IL-6, and IL-8 expression levels may have some predictable effects on metastatic breast cancer, especially bone metastases.%  目的:探讨溶血磷脂酸(lysophosphatidic acid,LPA)及其受体和IL-6与IL-8在乳腺癌进展中的表达及临床意义。方法:采用半定量RT-PCR方法检测乳腺肿瘤组织和瘤旁组织中LPA受体的表达水平。采用LPA生化测定法和酶联免疫吸附(ELISA)法分别检测乳腺肿瘤患者和健康妇女的血浆LPA、IL-6和IL-8水平。结果:术后复发转移乳腺癌患者血浆LPA、IL

    Full Text Available KIOM-MA was recently reported as a novel herbal medicine effective for atopic dermatitis and asthma. In this study, we have demonstrated the inhibitory effect of KIOM-MA on proinflammatory mediator produced in lipopolysaccharide (LPS-stimulated RAW 264.7 cells. KIOM-MA significantly inhibited the expression of inducible nitric oxide synthase (iNOS and cyclooxygenase-2 (COX-2 as well as nitric oxide (NO and prostaglandin E2 (PGE2. Consistent with the inhibitory effect on PGE2, KIOM-MA suppresses the LPS-induced migration of macrophages and gelatinase activity and the expression of matrix metalloprotease-9 (MMP-9 in a dose-dependent manner. Additionally, KIOM-MA showed a strong suppressive effect on the inflammatory cytokines production such as tumor necrosis factor-α (TNF-α and interleukin-6 (IL-6. We also found that KIOM-MA inhibits the activation of nuclear factor-κB (NF-κB and represses the activity of extracellular signal-regulated kinase (ERK, p38, and c-Jun NH2-terminal kinase (JNK mitogen-activated protein kinases (MAPKs. Taken together, we elucidated the mechanism of anti-inflammatory effect of KIOM-MA using RAW 264.7 cells stimulated by LPS.

    The cytokine interleukin-1 (IL-1) has been strongly implicated in the pathogenesis of ischemic brain damage. Evidence to date suggests that the major form of IL-1 contributing to ischemic injury is IL-1beta rather than IL-1alpha, but this has not been tested directly. The objective of the present study was to compare the effects of transient cerebral ischemia [30 min middle cerebral artery occlusion (MCAO)] on neuronal injury in wild-type (WT) mice and in IL-1alpha, IL-1beta, or both IL-1alpha and IL-1beta knock-out (KO) mice. Mice lacking both forms of IL-1 exhibited dramatically reduced ischemic infarct volumes compared with wild type (total volume, 70%; cortex, 87% reduction). Ischemic damage compared with WT mice was not significantly altered in mice lacking either IL-1alpha or IL-1beta alone. IL-1beta mRNA, but not IL-1alpha or the IL-1 type 1 receptor, was strongly induced by MCAO in WT and IL-1alpha KO mice. Administration (intracerebroventricularly) of recombinant IL-1 receptor antagonist significantly reduced infarct volume in WT (-32%) and IL-1alpha KO (-48%) mice, but had no effect on injury in IL-1beta or IL-1alpha/beta KO mice. These data confirm that IL-1 plays a major role in ischemic brain injury. They also show that chronic deletion of IL-1alpha or IL-1beta fails to influence brain damage, probably because of compensatory changes in the IL-1 system in IL-1alpha KO mice and changes in IL-1-independent mediators of neuronal death in IL-1beta KO mice.

    Reduced expression of autophagy regulators has been observed in pathological cartilage in humans and mice. The present study aimed to investigate the synergistic therapeutic effect of promotion of chondrocyte autophagy via exposure to sinomenium (SIN) encapsulated by chitosan microspheres (CM-SIN) and photo-crosslinked gelatin methacrylate (GelMA) hydrogel, with the goal of evaluating CM-SIN as a treatment for patients with osteoarthritis. First, we fabricated and characterized GelMA hydrogels and chitosan microspheres. Next, we measured the effect of SIN on cartilage matrix degradation induced by IL1-β in chondrocytes and an ex vivo model. SIN ameliorated the pathological changes induced by IL1-β at least partially through activation of autophagy. Moreover, we surgically induced osteoarthritis in mice, which were injected intra-articularly with CM-SIN and GelMA. Cartilage matrix degradation and chondrocyte autophagy were evaluated 4 and 8 weeks after surgery. Treatment with the combination of CM-SIN and GelMA retarded the progression of surgically induced OA. SIN ameliorated cartilage matrix degradation at least partially by inducing autophagy in vivo. Our results demonstrate that injection of the combination of GelMA hydrogel and CM-SIN could be a promising strategy for treating patients with osteoarthritis.

    2015-01-01

    Full Text Available Interleukin- (IL- 38 is a recently discovered cytokine and is the tenth member of the IL-1 cytokine family. IL-38 shares structural features with IL-1 receptor antagonist (IL-1Ra and IL-36Ra. IL-36R is the specific receptor of IL-38, a partial receptor antagonist of IL-36. IL-38 inhibits the production of T-cell cytokines IL-17 and IL-22. IL-38 also inhibits the production of IL-8 induced by IL-36γ, thus inhibiting inflammatory responses. IL-38-related cytokines, including IL-1Ra and IL-36Ra, are involved in the regulation of inflammation and immune responses. The study of IL-38 and IL-38-related cytokines might provide new insights for developing anti-inflammatory treatments in the near future.

    Full Text Available Il volume intende mettere in luce il valore attuale delle teorie e pratiche educativo-pedagogiche proposte da Maria Edgeworth. Agli albori della scienza moderna, Edgeworth si muove in un milieu assolutamente stimolante, che raccoglie alcuni tra i più grandi pensatori dell’epoca in ambito filosofico, educativo e culturale. La loro influenza, anche e soprattutto attraverso il lavoro costantemente sviluppato col padre, la porterà in pochi anni a formulare teorie educative che troveranno subito ampio riscontro presso la comunità intellettuale. La grande novità del suo progetto risiede nell’elaborazione di un sistema pedagogico coerente, basato su testi teorici e pratici ideati e composti in un linguaggio specifico di matrice scientifica ma con intento divulgativo, per l’educazione del bambino fino all’età della maturità. Pur mettendo in luce i limiti storici di alcuni presupposti del pensiero edgeworthiano, appare importante sottolineare l’attualità e l’attuabilità della sua proposta metodologica, fondata su indagini circostanziate e documentate secondo criteri oggi considerati basilari per la corretta attuazione della pratica educativa, che deve coinvolgere fattivamente il bambino e l’adulto. Maria Edgeworth supera la letteratura, quindi, per rivelarsi un assistant scientifico allo sviluppo dell’individuo in una società civile, moderna e in continua evoluzione.Profilo biograficoRaffaella Leproni è ricercatore di Lingua e traduzione inglese presso il Dipartimento di Scienze della Formazione dell’Università degli Studi Roma Tre, dove svolge didattica in diversi Corsi di Studio utilizzando materiali autentici di matrice socio-pedagogica ed educativa in prospettiva CLIL; collabora sul tema ad un progetto sperimentale con la Pädagogische Hochschule di Salisburgo.

    Full Text Available Ci si può chiedere quale sia il motivo che spinge ad affrontare la non facile prova consistente nel delineare un percorso di riflessione in chiave filosofica intorno al concetto di “popolo” prendendo in esame il periodo che va dalla prima alla tarda modernità, sino a sfiorare (almeno l’epoca della quale noi, uomini e donne del presente, siamo protagonisti, il più delle volte molto perplessi e parecchio disorientati.Il perché sta nel tentativo di mostrare che, per quanto questo lungo periodo sia, a proposito del nostro argomento, parecchio complesso e contraddistinto da un esteso pluralismo di punti di vista, presenta però, a mio avviso, almeno una caratteristica unitaria. Si tratta della difficoltà di articolare teoreticamente un concetto di “popolo” sul quale non gravino quei limiti sui quali vorrei concentrare l’attenzione: limiti ovviamente non secondari, ma tali da compromettere gravemente il concetto in questione.In tutto il tragitto che proverò a tracciare, non vorrei semplicemente procedere prendendo nota dei punti oscuri rinvenibili in questa o quella concezione di “popolo”, e così mettere in atto una sorta d’incolore e, tutto sommato, ridondante elenco che collochi uno dopo l’altro gli autori come in una galleria dei nobili fallimenti della filosofia politica dal ‘500 a oggi. La posta in gioco è ben diversa. La presento, per ora molto concisamente, come segue.Nel De republica di Cicerone – importante sintesi di una già consolidata tradizione – è evidente la corrispondenza concettuale tra “res publica” e “populus”: la società politica si dà solo in presenza di un’associazione tenuta insieme “per accordo nell’osservare la giustizia” e “per comunanza di interessi”. Il popolo, che si forma a causa della “naturale inclinazione a vivere bene” presente in ogni essere umano, esprime, nella sua unità etico-giuridica, il senso propriamente politico insito nel condurre un

    This software is provided by the Mars Relay Operations Service (MaROS) task to a variety of Mars projects for the purpose of coordinating communications sessions between landed spacecraft assets and orbiting spacecraft assets at Mars. The Information Management Service centralizes a set of functions previously distributed across multiple spacecraft operations teams, and as such, greatly improves visibility into the end-to-end strategic coordination process. Most of the process revolves around the scheduling of communications sessions between the spacecraft during periods of time when a landed asset on Mars is geometrically visible by an orbiting spacecraft. These relay sessions are used to transfer data both to and from the landed asset via the orbiting asset on behalf of Earth-based spacecraft operators. This software component is an application process running as a Java virtual machine. The component provides all service interfaces via a Representational State Transfer (REST) protocol over https to external clients. There are two general interaction modes with the service: upload and download of data. For data upload, the service must execute logic specific to the upload data type and trigger any applicable calculations including pass delivery latencies and overflight conflicts. For data download, the software must retrieve and correlate requested information and deliver to the requesting client. The provision of this service enables several key advancements over legacy processes and systems. For one, this service represents the first time that end-to-end relay information is correlated into a single shared repository. The software also provides the first multimission latency calculator; previous latency calculations had been performed on a mission-by-mission basis.

Nel contesto attuale, dove l'evoluzione della tecnologia spesso supera quella delle strutture organizzative, e' opportuno ridisegnare il Sistema Informativo Gestionale, considerando il fatto che spesso le procedure informatiche gestionali risultano obsolescenti. L'impostazione del lavoro svolto si basa sull'osservazione del processo di gestione aziendale: al fine di raggiungere i suoi obiettivi, l'Azienda trasforma delle risorse, ciascuna con il proprio ciclo di vita, attraverso fasi di gestione classificabili in valutazione, decisione, esecuzione e controllo. Tali fasi sono attuate attraverso il trattamento delle informazioni che rappresentano il legame tra esse nonche' la risorsa principale dell'intera organizzazione e il cardine del Sistema Informativo Gestionale.

    It has been shown that IL-2 and IL-15 can have opposing effects on life and death of T cells. However, the role of IL-2 and IL-15 in regulating the fate of other cell types is less clear. In the present study, we examined the impact of IL-2 and IL-15 on life and death of pre-B cells using the BAF-B03 line. We showed that BAF-B03 cells constitutively expressed the private IL-2Rα chain and IL-15Rα chain, and the shared IL-2Rβ chain and γc chain. Stimulation of BAF-B03 cells in vitro with IL-2 and IL-15 induced vigorous cell proliferation in a dose-dependent fashion. Titration of IL-2 and IL-15 in the assay showed that the mitotic effects of IL-2 and IL-15 were remarkably similar, Howerer, the sensitivities of BAF-B03 cells to Fas mediated apoptosis after IL-2 and IL-15 stimulation were strikingly different. Cells cultured in IL-2 readily underwent apoptotic cell deathupon cross-linking of the Fas receptor whereas cells cultured in IL-15 were extremely resistant to Fas triggered cell death. The anti-apoptotic effect of IL-15 in this model was associated with increased expression of Bcl-xL. FLIP expression, however, was comparable between IL-2 and IL-15 stimulated cells. We conclude that IL-2 and IL-15 have diametrically opposite effect on the fate of BAF-B03 cells, although both cytokines share similar receptor structure and exhibitsimilarmitoticactivities.

IL-2, IL-7, IL-15 and IL-21, sharing a common receptor γ chain (c-γ, control T lymphocyte homeostasis and proliferation and play major roles in regulating cancer-immune system interactions. We evaluated local IL-2, IL-7, IL-15 and IL-21 gene expression in prostate tissues from patients with early stage PCA or benign prostatic hyperplasia (BPH. As control, we used IL-6 gene, encoding an IL involved in PCA progression. IL-6, IL-7 and IL-15 titres were also measured in patients' sera. Methods Eighty patients with BPH and 79 with early (1 to 2c stage PCA were enrolled. Gene expression in prostate tissues was analyzed by quantitative real-time PCR (qRT-PCR. Serum IL concentrations and acute phase protein titres were evaluated by ELISA. Mann-Whitney, Wilcoxon and χ2 tests were used to compare IL gene expression and serum titers in the two groups of patients. Receiver operating characteristic (ROC curves were constructed to evaluate the possibility to distinguish sera from different groups of patients based on IL titers. Results IL-2 and IL-21 gene expression was comparably detectable, with low frequency and at low extents, in PCA and BPH tissues. In contrast, IL-6, IL-7 and IL-15 genes were expressed more frequently (p Conclusions Expression IL-7 and IL-15 genes in prostate tissues and corresponding serum titres are significantly increased in patients with early stage PCA as compared with patients with BPH.

  13. The role of IL-4 and IL-13 in cutaneous Leishmaniasis.

    Science.gov (United States)

    Hurdayal, Ramona; Brombacher, Frank

    2014-10-01

    Murine models of Leishmania major infection in the 1980s revealed two distinct, counter-regulatory populations of CD4(+) T helper (Th) cells, delineated Th1 and Th2, and their archetypal cytokines, interferon gamma (IFN-γ) and interleukin (IL)-4/IL-13, which promoted resistance/susceptibility to infection, respectively. However, the introduction of global cytokine-deficient mice in the 1990s revealed pleiotropic immune-regulatory mechanisms of IL-4 and IL-13 that either controlled or exacerbated disease. This undermined the basic premise that IL-4/IL-13 played paramount roles in facilitating a non-healing Th2 response to Leishmania infection and instead suggested that both IL-4 and IL-13-dependent and IL-4/IL-13-independent factors orchestrate disease outcome. The recent characterization of cell-type specific IL-4Rα deficient mice was initiated to help reconcile these observations and dissect the cell-specific effects of IL-4/IL-13 during infection. In this review, we summarize original and recent findings with regard to the role of IL-4 and IL-13 in cutaneous Leishmaniasis. Using the information discerned from various studies and our conditional IL-4Rα gene-deficient mice, we particularly discuss the double-edged sword IL-4 (and in some Leishmania disease models IL-13) in driving a susceptible Th2 response, their immune cell targets that support healing or non-healing responses and their novel role in mediating a Th1 response during disease.

    The 126Gln of human interleukin-2 (IL-2) is a conserved amino acid residue. After substitution of 126Gln with Asp, the binding abilities of this mutant to different composites of IL-2 receptor (R) subunits have been determined. Results show that 126Asp-IL-2 has higher affinity to IL-2R α βγ complex and normal affinity to IL-2R α β complex, but loses its binding ability to IL-2R β γ complex, demonstrating that the 126Gln is the residue of human IL-2 which binds to IL-2R 7 subunit.

    The Interleukin (IL)-12 family contains several heterodimeric composite cytokines which share subunits among each other. IL-12 consists of the subunits p40 (shared with IL-23) and p35. p35 is shared with the composite cytokine IL-35 which comprises of the p35/EBI3 heterodimer (EBI3 shared with IL-27). IL-35 signals via homo- or heterodimers of IL-12Rβ2, gp130 and WSX-1, which are shared with IL-12 and IL-27 receptor complexes, respectively. p35 was efficiently secreted in complex with p40 as IL-12 but not with EBI3 as IL-35 in several transfected cell lines tested which complicates the analysis of IL-35 signal transduction. p35 and p40 but not p35 and EBI3 form an inter-chain disulfide bridge. Mutation of the responsible cysteine residue (p40C197A) reduced IL-12 formation and activity only slightly. Importantly, the p40C197A mutation prevented the formation of antagonistic p40 homodimers which enabled the in vitro reconstitution of biologically active IL-12 with p35 produced in bacteria (p35bac). Reconstitution of IL-35 with p35bac and EBI3 did, however, fail to induce signal transduction in Ba/F3 cells expressing IL-12Rβ2 and gp130. In summary, we describe the in vitro reconstitution of IL-12, but fail to produce recombinant IL-35 by this novel approach.

    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.

  18. Tumorigenicity of IL-1α– and IL-1β–Deficient Fibrosarcoma Cells

    Full Text Available Analyzing the growth of fibrosarcoma lines derived from IL-1α–, IL-1β–, or IL-1αβ–knockout (−/− mice in the immunocompetent host revealed that tumor-derived IL-1α and IL-1β exert strong and opposing effects on immune response induction, which prohibited the evaluation of a potential impact on tumorigenicity. Therefore, in vivo growth of IL-1–deficient tumor lines was evaluated in nu/nu mice and was compared with in vitro growth characteristics. All IL-1–deficient fibrosarcoma lines grow in immunocompromised mice. However, IL-1α−/−β–competent (comp lines grow more aggressively, efficiently induce angiogenesis, and recruit inflammatory cells. Despite stronger tumorigenicity of IL-1βcomp lines, IL-1α strengthens anchorage-independent growth, but both IL-1α and IL-1β support drug resistance. Corresponding to the aggressive growth, IL-1βcomp cells display increased matrix adhesion, motility, and cable formation on matrigel, likely supported by elevated αv/β3 and matrix metalloproteinase expression. Recruitment of myeloid cells requires IL-1β but is regulated by IL-1α, because inflammatory chemokine and cytokine expression is stronger in IL-1α−/−βcomp than in IL-1wt lines. This regulatory effect of tumorderived IL-1α is restricted to the tumor environment and does not affect systemic inflammatory response induction by tumor-derived IL-1β. Both sarcoma cell–derived IL-1α and IL-1β promote tumor growth. However, IL-1α exerts regulatory activity on the tumor cell–matrix cross-talk, and only IL-1β initiates systemic inflammation.

    Tra i tanti oggetti pervasivi ed elusivi che affollano la dimensione invisibile del mondo subatomico, il "bosone di Higgs" è stato il più pervasivo ed elusivo: quella particella era l'elemento cruciale che mancava a completare il puzzle del Modello Standard, perché conferiva massa a tutte le altre particelle elementari, un enigma rimasto altrimenti insoluto. Quando finalmente il 4 luglio 2012 il CERN ne ha annunciato la verifica sperimentale, la "particella di Dio" (come un fisico l'ha temerariamente denominata) ha attirato su di sé i riflettori dell'attenzione mediatica mondiale. Affrontando l'intera questione con un rigore che ne acuisce la densità intellettuale e la vertigine tecnologica, Jim Baggott segue due percorsi paralleli.

  1. Involvement of IL17A, IL17F and IL23R Polymorphisms in Colorectal Cancer Therapy.

    Full Text Available IL23/IL17 pathway plays an important role in the development of inflammatory bowel diseases (IBD. In general, the genes encoding the cytokines are genetically polymorphic and polymorphisms in genes IL23R and IL17 have been proved to be associated with its susceptibility to inflammatory diseases as well as cancer including colorectal cancer. Moreover, it has been shown that these interleukins are involved in anti-tumor or pro-tumor effects of various cancers. Previously, we showed that there is a significant association between IL17A, IL17F and IL23R polymorphisms as well as the occurrence of colorectal cancer and the clinical features of the disease. The purpose of the present work is to investigate an association between IL17A, IL17F and IL23R polymorphisms in 102 Tunisian patients with colorectal cancer treatment. The association was analyzed by statistical tools. We found that patients with mutated genotypes of IL17A G197A SNP could be a risk factor for the inefficiency of chemotherapy and radiotherapy. Unlike IL17F variant, patients with wild type genotypes require surgery and adjuvant chemotherapy. On the one hand, we found no evidence that supports a significant association between IL23R polymorphism and the combined genotypes of these three genes and the colorectal cancer treatment. On the other hand, we showed that there is an important interaction between IL17A/IL17F polymorphisms and the stage of the disease as well as its treatment. Finally, patients with IL17F wild type genotype highlighted that there is a valid longer OS without all treatments and with radiotherapy and a neoadjuvant chemotherapy. In contrast, we observed that there are no relationships between IL17A, IL23R and the survival of these patients neither with nor without the treatment. Our results suggest that polymorphisms in IL17A and IL17F genes may be a predictive source of colorectal cancer therapy type. Therefore, IL17F may serve as an independent prognostic factor

    Full Text Available Il paesaggio è un’entità spaziale complessa, nella quale troviamo registrate, sedimentate nel tempo, le trasformazioni di genere naturale e culturale, espresse con un linguaggio universalmente comprensibile in un testo unico e fragile. A questa concezione matura del paesaggio si può riferire il suo riconoscimento come indicatore di sintesi dello stato dell’ambiente, che l’ex Agenzia nazionale per la protezione dell’ambiente proponeva sul finire degli anni Novanta, indicando pertanto una possibile via, non semplice, né esaustiva, ma chiara e praticabile, per l’analisi e il progetto della sostenibilità dello sviluppo territoriale. La stessa definizione olistica che la Convenzione europea attribuisce al paesaggio costituisce una conferma ed un rafforzamento del suo significato quale esito primario delle modalità di sviluppo territoriale e pertanto della sua valenza di termine di valutazione delle relative condizioni di sostenibilità.

    From NCBI Gene: The protein encoded by this gene is a pleiotropic cytokine produced by activated T cells. This cytokine is a ligand for interleukin 4 receptor. The interleukin 4 receptor also binds to IL13, which may contribute to many overlapping functions of this cytokine and IL13. STAT6, a signal transducer and activator of transcription, has been shown to play a central role in mediating the immune regulatory signal of this cytokine. This gene, IL3, IL5, IL13, and CSF2 form a cytokine gene cluster on chromosome 5q, with this gene particularly close to IL13. This gene, IL13 and IL5 are found to be regulated coordinately by several long-range regulatory elements in an over 120 kilobase range on the chromosome. Two alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported. [provided by RefSeq, Jul 2008

    IL-4 was identified as the first cytokine to be produced by mast cells and is responsible for promoting mast cell IL-13 production. IL-4 and IL-13 play a prominent role in stimulating and maintaining the allergic response. As closely related genes, IL-4 and IL-13 share a common receptor subunit, IL-4Rα, necessary for signaling. Here we summarize the literature on mast cell activation associated with IL-4 and IL-13 production, including downstream signaling. We also describe the positive and negative roles each cytokine plays in mast cell immunity and detail the differences that exist between mouse and human mast cell responses to IL-4 and IL-13.

    Full Text Available Quali sono i criteri in riferimento ai quali è possibile parlare di cambiamento in psicoterapia psicoanalitica? Cosa lo determina? Quali sono i meccanismi coinvolti nel processo? Per rispondere a queste domande occorre accordarsi su cosa si intenda per cambiamento. Si parla di cambiamento, infatti, sia in riferimento all'esito finale del percorso psicoterapico che relativamente alle modificazioni e agli obiettivi che caratterizzano il processo in itinere. Intendendolo l'esito di una serie di modificazioni strutturali, durature nel tempo, esso si produce attraverso il contributo di numerose variabili tecniche e teoriche, tutte inserite in una logica bi-personale: dalla lettura della modalità relazionale del paziente quale derivato dei Modelli Operativi Interni, all'interiorizzazione di una nuova esperienza relazionale, dal ruolo giocato dall'alleanza terapeutica quale premessa ed esito del lavoro psicoterapico, all'interpretazione e agli interventi del continuum supportivo-espressivo etc. In questa direzione il concetto di cambiamento, nel promuovere una presa di coscienza circa le modalità relazionali che avrebbero determinato la richiesta di intervento psicologico, starebbe per l'acquisizione, da parte della persona, degli strumenti necessari a massimizzare l'espressione di sé e la valorizzazione della propria autonomia e risorse, ai fini del raggiungimento di un più funzionale adattamento all'ambiente, proprio di una condizione di benessere e di un atteggiamento ad essa orientato.

    The relative contributions of interleukin-12 (IL-12) and IL-23 to viral pathogenesis have not been extensively studied. IL-12p40 mRNA rapidly increases after neurotropic coronavirus infection. Infection of mice defective in both IL-12 and IL-23 (p40(-/-)), in IL-12 alone (p35(-/-)), and in IL-23 alone (p19(-/-)) revealed that the symptoms of coronavirus-induced encephalitis are regulated by IL-12. IL-17-producing cells never exceeded background levels, supporting a redundant role of IL-23 in pathogenesis. Viral control, tropism, and demyelination were all similar in p35(-/-), p19(-/-), and wild-type mice. Reduced morbidity in infected IL-12 deficient mice was also not associated with altered recruitment or composition of inflammatory cells. However, gamma interferon (IFN-gamma) levels and virus-specific IFN-gamma-secreting CD4 and CD8 T cells were all reduced in the central nervous systems (CNS) of infected p35(-/-) mice. Transcription of the proinflammatory cytokines IL-1beta and IL-6, but not tumor necrosis factor, were initially reduced in infected p35(-/-) mice but increased to wild-type levels during peak inflammation. Furthermore, although transforming growth factor beta mRNA was not affected, IL-10 was increased in the CNS in the absence of IL-12. These data suggest that IL-12 does not contribute to antiviral function within the CNS but enhances morbidity associated with viral encephalitis by increasing the ratio of IFN-gamma to protective IL-10.

  8. IL-27 Regulates IL-18 binding protein in skin resident cells.

    Directory of Open Access Journals (Sweden)

    Miriam Wittmann

    Full Text Available IL-18 is an important mediator involved in chronic inflammatory conditions such as cutaneous lupus erythematosus, psoriasis and chronic eczema. An imbalance between IL-18 and its endogenous antagonist IL-18 binding protein (BP may account for increased IL-18 activity. IL-27 is a cytokine with dual function displaying pro- and anti-inflammatory properties. Here we provide evidence for a yet not described anti-inflammatory mode of action on skin resident cells. Human keratinocytes and surprisingly also fibroblasts (which do not produce any IL-18 show a robust, dose-dependent and highly inducible mRNA expression and secretion of IL-18BP upon IL-27 stimulation. Other IL-12 family members failed to induce IL-18BP. The production of IL-18BP peaked between 48-72 h after stimulation and was sustained for up to 96 h. Investigation of the signalling pathway showed that IL-27 activates STAT1 in human keratinocytes and that a proximal GAS site at the IL-18BP promoter is of importance for the functional activity of IL-27. The data are in support of a significant anti-inflammatory effect of IL-27 on skin resident cells. An important novel property of IL-27 in skin pathobiology may be to counter-regulate IL-18 activities by acting on keratinocytes and importantly also on dermal fibroblasts.

    Genetic predisposition to coeliac disease (CD) is determined primarily by alleles at the HLA-DQB locus, and evidence exists implicating other major histocompatibility complex-linked genes (6p21) and the CTLA4 locus on chromosome 2q33. In addition, extensive family studies have provided strong, reproducible evidence for a susceptibility locus on chromosome 5q (CELIAC2). However, the gene responsible has not been identified. We have assayed genetic variation at the IL4, IL5, IL9, IL13, IL17B and NR3C1 (GR) loci, all of which are present on chromosome 5q and have potential or demonstrated involvement in autoimmune and/or inflammatory disease, in a sample of 409 CD cases and 355 controls. Thirteen single nucleotide polymorphisms were chosen on the basis of functional relevance, prior disease association and, where possible, prior knowledge of the haplotype variation present in European populations. There were no statistically significant allele or haplotype frequency differences between cases and controls. Therefore, these results provide no evidence that these loci are associated with CD in this sample population.

    2011-12-01

    Full Text Available The aim of this paper is to describe and interpret suiform teeth from Moroto, Uganda, and Ngorora, Kenya, which contribute to the debate about hippo-anthracothere-whale relationships. The early stages of hippopotamid evolution are relatively poorly known on account of the paucity of their fossil record older than 7 Ma. New specimens of Morotochoerus from Uganda reveal that it is not closely related to Hippopotamidae; the superficial resemblances of the cheek teeth to those of hippos represent convergences and not homologies. Restricted samples of Palaeopotamus ternani are available from the Middle Miocene of Kenya {Maboko, ca 16 Ma; Muruyur, ca 14.5 Ma; Fort Ternan, ca 13.7 Ma} while from the base of the late Miocene, Kenyapotamus coryndonae is known from Kenya {Ngerngerwa, ca 10.5-10 Ma; Nakali, ca 10.5 Ma; Samburu Hills, ca 9.5 Ma}, Ethiopia {Ch’orora, ca 10.5 Ma} and Tunisia {Beglia Formation ca 11-10 Ma}. The recovery of specimens of Kenyapotamus from the Ngorora Formation, Kenya, aged ca 11 Ma, is of interest because it includes well preserved teeth, including an m/3 in good condition. These specimens support the hypothesis that hippopotamids descended from palaeochoerids and not from anthracotheres.El objetivo de este trabajo es describir e interpretar los dientes suiformes de Moroto, Uganda, y Ngorora, Kenia, que contribuyen al debate sobre las relaciones hipo-anthracothere-whale.

Results The levels of slL-2R, IL-6 and IL-8 were higher and IL-2 was lower during acute stage than those in the normal subjects (P <0. 01). Compared those during the convalescent stage, the level of IL-2 was higher and sIL-2R, IL-6 and IL-8 were lower (P <0. 01) during the acute stage. There were not any significant differences of the levels of these four substances between the normal children and MPP children during the convalescent stage. Conclusion The cellular immune function of children with MPP is impaired and the changes of IL-2, sIL-2R, IL-6 and IL-8 can be used to evaluate the curative effects and prognosis of MPP in children.

    Previous studies have indicated that autoimmune diseases might be caused by an imbalance of T helper cells (Th), cytokines, and regulatory T cells (Treg) cytokines. We measured the plasma concentrations of Th1-associated cytokines (IFN-gamma, IL-2), Th2 -associated cytokines (IL-4, IL-10), Th17-associated cytokine (IL-17) and Treg -associated cytokine (TGF-beta1) in adult patients with immune thrombocytopenia (ITP) and evaluated their clinical relevance. Plasma IFN-gamma, IL-2, IL-4, IL-10, IL-17 and TGF-beta1 concentrations of 52 ITP patients and 30 age- and sex-matched healthy controls were measured by enzyme-linked immunosorbent assay method (ELISA). Concentration of Th2 cytokines (IL-4 and IL-10) were significantly higher in ITP patients compared to controls (P cytokines (IFN-gamma, IL-2), Th17 cytokine (IL-17) and Treg cytokine (TGF-beta1) were lower in ITP patients (P cytokine concentration among the other subgroups in ITP patients was found. Among the ITP patients, concentration of IFN-gamma correlated positively and significantly with PAIgG (r = 0.48, P = 0.02). A significant correlation was neither found between other cytokine levels and platelet count, nor between cytokine levels and megakaryocytes number, nor between cytokines levels and PAIgG or GPIIb/IIIa and/or GPIb/IX autoantibodies. The present study demonstrates that an imbalance of Th and Treg cytokines may mediate the pathogenesis of ITP.

    2016-05-01

    IL-25, also named IL-17E, is a distinct member of the IL-17 cytokine family, which can promote and augment T helper type 2 (Th2) responses locally or systemically. Growing evidence from experimental and clinical studies indicates that the expression of IL-25 and its cognate receptor, IL-17RB/RA, is markedly upregulated in asthmatic conditions. It has also been found that IL-25 induces not only typical eosinophilic inflammation and airway hyperresponsiveness (AHR), but also airway remodelling, manifested by goblet cell hyperplasia, subepithelial collagen deposition and angiogenesis. This review will focus on the discovery, cellular origins and targets of IL-25, and try to update current animal and human studies elucidating the roles of IL-25 in asthma. We conclude that although IL-25 is a pleiotropic cytokine, it may only play its dominant role in a certain specific asthmatic endotype, named 'IL-25 high' phenotype. Thus, targeting IL-25 or its receptor might selectively benefit some subgroups with asthma. Furthermore, the major IL-25 producing as well as responsive cells in the changeable milieu of asthma should be assessed in the future.

The study objective was to assess the effect of T. gondii on chosen indices of the immune response. The study involved 52 women infected with T. gondii (aged 18–42 years prior to antiparasitic treatment. In all the patients, we found IgM (index >0.7 and IgG which exceeded 300 IU/ml. The control group (C consisted of 40 healthy women aged 18–46 years. In the study group (T and in the control group (C, the levels of IgE, IL-5, IL-6, IL-10, IL-12, and TNF-α were determined. In our study, T. gondii patients had twofold higher levels of IL-5 and IL-6 as compared to healthy subjects, which seems to confirm the presence of an inflammatory state. We found the level of IL-10 to be fivefold higher in the course of toxoplasmosis than in healthy controls. The levels of IL-12 and TNF-α were comparable to those observed in healthy controls. The study has revealed that that patients infected with T. gondii show increased production of the humoral response cytokines, whereas the generation of the cell response cytokines remains unchanged.

    研究目的:分离和鉴定桑树中参与乙烯生物合成的酶的编码基因MaACS 和MaACO,研究其表达模式。创新要点:基于最新公布的桑树基因组数据库数据,获得5个MaACS 基因和2个MaACO 基因,对其进行了生物信息分析,同时鉴定了其在不同桑树组织中、不同发育时期桑椹中和不同激素作用下的表达模式。研究方法:通过生物信息学方法筛选和鉴定基因,利用荧光定量逆转录聚合酶链式反应(qRT-PCR)分析基因的表达量。重要结论:MaACS 和MaACO 基因在根、茎、叶等不同组织中呈现出不同的表达模式,在桑椹发育过程中呈现出两种表达模式,其表达量被脱落酸和乙烯利上调。%1-Aminocyclopropane-1-carboxylic acid synthase (ACS) and 1-aminocyclopropane-1-carboxylic acid oxidase (ACO) are encoded by multigene families and are involved in fruit ripening by catalyzing the production of ethylene throughout the development of fruit. However, there are no reports on ACS or ACO genes in mulberry, partly because of the limited molecular research background. In this study, we have obtained five ACS gene sequences and two ACO gene sequences from Morus Genome Database. Sequence alignment and phylogenetic analysis of MaACO1 and MaACO2 showed that their amino acids are conserved compared with ACO proteins from other species. MaACS1 and MaACS2 are type I, MaACS3 and MaACS4 are type II, and MaACS5 is type III, with different C-terminal se-quences. Quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) expression analysis showed that the transcripts of MaACS genes were strongly expressed in fruit, and more weakly in other tissues. The expression of MaACO1 and MaACO2 showed different patterns in various mulberry tissues. MaACS and MaACO genes demon-strated two patterns throughout the development of mulberry fruit, and both of them were strongly up-regulated by abscisic acid (ABA) and ethephon.

    Full Text Available In un contesto di ineguale distribuzione delle risorse idriche, di crescita demografica e di sviluppo economico, l’acqua assume sempre più il ruolo divariabile strategica in grado di alterare gli equilibri geopolitici soprattutto in quelle aree in cui le fonti idriche sono condivise tra più paesi. Obiettivo dell’articolo è quello di analizzare il contenzioso idrico del bacino del Tigri e dell’Eufrate dove la storica disputa per la gestione e l’accaparramento delle acque condivise tra Turchia, Siria e Iraq è acuita dall’effetto del cambiamento climatico e dall’ingresso di nuovi attori nel controllo della risorsa. L’aumento della frequenza e dell’intensità dei periodi di siccità amplifica il gap tra domanda e offerta idrica mentre il nuovo ordine idropolitico disegnato dall’espansione dello Stato Islamico, limita l’accesso alla risorsa da parte delle fasce più deboli delle popolazioni. Particolarmente penalizzate sono le donne a cui viene quotidianamente affidato l’arduo compito di gestire le scarse risorse idriche e di allocarle tra i diversi usi. Il controllo da parte dello Stato islamico delle grandi dighe lungo il corso dei due fiumi, l’utilizzo dell’acqua come strumento di pressione e il conseguente deterioramento qualitativo e quantitativo della risorsa, non solo aumentano la quantità di lavoro che le donne devono impiegare per la raccolta e la distribuzione dell’acqua ma minacciano la sicurezza alimentare e la salute loro e delle loro famiglie.

    Interleukin 15 (IL-15) expression induces the secretion of inflammatory cytokines, inhibits the apoptosis of activated T cells and prolongs the survival of CD8+ memory T cells. Here we identified an IL-15 isoform lacking exon-6, IL-15ΔE6, generated by alternative splicing events of activated immune cells, including macrophages and B cells. In vitro study showed that IL-15ΔE6 could antagonize IL-15-mediated T cell proliferation. The receptor binding assay revealed that IL-15ΔE6 could bind to IL-15Rα and interfere with the binding between IL-15 and IL-15Rα. Over-expression of IL-15ΔE6 in the murine EAE model ameliorated the EAE symptoms of the mice. The clinical scores were significantly lower in the mice expressing IL-15ΔE6 than the control mice and the mice expressing IL-15. The inflammation and demyelination of the EAE mice expressing IL-15ΔE6 were less severe than the control group. Furthermore, flow cytometry analysis demonstrated that IL-15ΔE6 expression reduced the percentages of inflammatory T cells in the spleen and spinal cord, and inhibited the infiltration of macrophages to the CNS. Our results demonstrated that IL-15ΔE6 could be induced during immune activation and function as a negative feedback mechanism to dampen IL-15-mediated inflammatory events. PMID:27166125

    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.

  10. Biological significance of soluble IL-2 receptor

    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

    Objective:To determine the levels ofIL-18 andIL-18binding protein(BP) in patients with dengue virus infection.Methods: Acute and convalescent sera were collected from each patient. Control group was sera from blood donors. The levels of both IL-18 andIL-18BP were measured byELISA assays.Results: It was shown thatIL-18 andIL-18BPlevels were significantly higher in patients when compared with controls. In addition, the level ofIL-18BP was lower in convalescent than in acute sera.Conclusions: These data suggest that bothIL-18 andIL-18BP production was induced following dengue virus infection. Investigating the regulation of IL-18 by its natural regulator could lead to further understanding of the immune response or immunopathogenesis following dengue virus infection.

Methods: One hundred and forty-eight patients and one hundred and thirty-two healthy control subjects were included in the study. Clinical parameters (PI, GI and PD) and GCF levels of IFN-γ, IL-10 and IL-17 were measured at baseline, week 8, week 16 and week 24 after mechanical removal of dental plaque. IFN-γ and IL-10 were determined with ELISA methods and IL-17 was determined with the cytometric bead array. Results: Removal of dental plaque resulted in improvement in all clinical parameters. Meanwhile, GCF IL-17 declined to control levels, while GCF IFN-γ and IL-10 levels remained unchanged. Conclusions: The decline of GCF IL-17 levels in patients with resolution of periodontitis suggests that IL-17 is involved in the periodontal inflammatory process.

    Directory of Open Access Journals (Sweden)

    Francesco Margoni

    2013-05-01

    Full Text Available All’inizio del nuovo secolo lo psicologo Jonathan Haidt propone un modello del giudizio morale ch’entra in opposizione ad una duratura tradizione di pensiero, quella per cui il giudizio morale è causato dalla ragione. In psicologia, a sostenere il modello razionalista, sono stati, per lo più, Piaget e Kohlberg. Sul versante filosofico, possiamo affermare che buona parte degli addetti ai lavori si sono schierati a favore della concezione razionalistica. Razionalisti in morale erano Socrate, che introdusse l’intellettualismo etico, il cristianesimo, Cartesio, Kant. Haidt, invece, elaborando il suo modello descrittivo su dati sperimentali di natura empirica, arriva alla conclusione che il giudizio morale, nella maggior parte dei casi, non è causato dal ragionamento cosciente. Piuttosto, il ragionamento entrerebbe in gioco una volta formulato il giudizio morale, come forza di razionalizzazione a posteriori. Haidt chiama questo modello "intuizionista".

    Objective:To investigate the effects of interleukin-1beta (IL-1β) on expression of IL-8 in endometrial stromal cells (ESC) and evaluate the relationship between IL1 β and IL-8 ,and the significance of IL-1β in the development of endometriosis. Methods:The endometrial stromal cells obtained from patient with and without endometriosis cultured within 3 ~5 passage were exposed to various concentrations of IL-1β. The amount of IL-8 protein was assessed by ELISA. The expression of IL-8 mRNA was determined by RT-PCR. Results: 1. IL-8 protein was detected in culture supernatant of which the cells were not treated with IL-1β. The amount of IL-8 protein secretion increased obviously after stimulation with IL-1β at 1.0ng/ml for 4h and the peak of secretion was at 12h. 2. Expression of IL-8 mRNA was positive in unstimulated endometrial stromal cells. However, after stromal cells were incubated with IL-1β, the intensity of expression of IL-8 mRNA was obviously increased and demonstrated a dose-and timedependent manner. Increase of IL-8 mRNA was observed following stimulation with IL-1β for 4h ,and the peak at 12h. Conclusions:IL-1β induces endometrial stromal cell of endometriosis to express IL-8 not only at transcription level but also at post-transcription level. This up-regulation is dose-and time-dependent. IL-1β may play an important role in the onset of endometriosis.

  7. Umorismo e distopia: il riso entropico in Saramago e Ballard

    Full Text Available Se le maggiori distopie del Novecento sono tetri incubi d’ordine, d’implacabili meccanismi repressivi nelle mani di oligarchie dispotiche, la fine del secolo, e ancor più l’inizio del Ventunesimo, vedono il prevalere di apocalittiche visioni di entropia politico-sociale e collasso morale, capaci di portare non solo a un’assurda sofferenza universale, ma finanche all’estinzione della stessa vita sul pianeta. Colpisce come al mutare della forma si accompagni anche un cambiamento di tono, con l’affiorare di un umorismo nero che tradisce il senso di impotenza di fronte a un deragliamento che pare connaturato all’essere umano, e che sul piano della retorica si esprime (anche nel recupero ironico di modalità di narrazione anacronistiche e in parodie serie di testi fondativi della cultura occidentale. L’articolo esplora, confronta e discute le diverse strategie retoriche e umoristiche impiegate da José Saramago in Ensaio sobre a  cegueira (1995 e J.G. Ballard in High Rise (1975 per ritrarre scene ugualmente deprimenti di regressione alla barbarie, mettendo in evidenza la natura profondamente divergente della loro prospettiva.

    Proinflammatory cytokines, including interleukin (IL)-1beta, are known to modulate effects of neurotoxic neurotransmitters discharged during excitation or inflammation in the central nervous system (CNS). They also regulate development of glial scars at sites of CNS injury. To elucidate a genetic predisposition of temporal lobe epilepsy with hippocampal sclerosis (TLE-HS+), we studied polymorphisms in the IL-1beta, IL-1alpha, and IL-1 receptor antagonist (IL-1RA) genes in 50 patients with TLE-HS+ and in 112 controls. Fifty-three patients who had TLE without HS were also examined (TLE-HS-) as disease controls. The distribution of the biallelic polymorphism in the promoter region at position -511 of the IL-1beta gene (IL-1B-511) was significantly different both between TLE-HS+ patients and controls and between TLE-HS+ and TLE-HS- patients. The differences were due to overrepresentation of the homozygotes for IL-1B-511*2, which is suggested to be a high producer of IL-1beta, in TLE-HS+ patients compared with both controls and TLE-HS- patients. In contrast, there was no difference between TLE-HS- patients and controls. Our data suggest that, in the homozygotes for IL-IB-511*2, minor events in development such as febrile convulsions could set up a cascade leading to HS.

    Previous studies have shown that cells and cytokines associated with interleukin-17 (IL-17)-driven inflammation are involved in the arthritic response to Borrelia burgdorferi infection. Here, we report that IL-17 is a contributing factor in the development of Lyme arthritis and show that its production and histopathological effects are regulated by interleukin-10 (IL-10). Spleen cells obtained from B. burgdorferi-infected, "arthritis-resistant" wild-type C57BL/6 mice produced low levels of IL-17 following stimulation with the spirochete. In contrast, spleen cells obtained from infected, IL-10-deficient C57BL/6 mice produced a significant amount of IL-17 following stimulation with B. burgdorferi. These mice developed significant arthritis, including erosion of the bones in the ankle joints. We further show that treatment with antibody to IL-17 partially inhibited the significant hind paw swelling and histopathological changes observed in B. burgdorferi-infected, IL-10-deficient mice. Taken together, these findings provide additional evidence of a role for IL-17 in Lyme arthritis and reveal an additional regulatory target of IL-10 following borrelial infection.

    We are developing a new high explosive pulsed power (HEPP) system based on the 1.4 m long Ranchero generator which was developed in 1999 for driving solid density z-pinch loads. The new application requires approximately 40 MA to implode similar liners, but the liners cannot tolerate the 65 {micro}s, 3 MA current pulse associated with delivering the initial magnetic flux to the 200 nH generator. To circumvent this problem, we have designed a system with an internal start switch and four explosively formed fuse (EFF) opening switches. The integral start switch is installed between the output glide plane and the armature. It functions in the same manner as a standard input crowbar switch when armature motion begins, but initially isolates the load. The circuit is completed during the flux loading phase using post hole convolutes. Each convolute attaches the inner (coaxial) output transmission line to the outside of the outer coax through a penetration of the outer coaxial line. The attachment is made with the conductor of an EFF at each location. The EFFs conduct 0.75 MA each, and are actuated just after the internal start switch connects to the load. EFFs operating at these parameters have been tested in the past. The post hole convolutes must withstand as much as 80 kV at peak dl/dt during the Ranchero load current pulse. We describe the design of this new HEPP system in detail, and give the experimental results available at conference time. In addition, we discuss the work we are doing to test the upper current limits of a single standard size Ranchero module. Calculations have suggested that the generator could function at up to {approx}120 MA, the rule of thumb we follow (1 MA/cm) suggests 90 MA, and simple flux compression calculations, along with the {approx}4 MA seed current available from our capacitor bank, suggests 118 MA is the currently available upper limit.

    I present an overview of the scientific motivation and basic design of the Sloan Digital Sky Survey-IV program, MaNGA: Mapping Nearby Galaxies at Apache Point Observatory. MaNGA is currently in its second year of operations with roughly 2000 galaxies now observed, already the largest integral field spectroscopic survey of galaxies ever conducted. By combining the wealth of information made available by resolved spectroscopy with the statistical power of a sample of 10,000 galaxies, MaNGA is providing transformative insights on key questions about the life history of galaxies. These questions range from the nature of growth of star-forming disks and stellar spheroidals, to the physical origin of star formation quenching, to the ways in which the different mass components in galaxies interact and assemble over time. MaNGA's success owes to a dedicated team of scientists, engineers, and observers working to optimize the survey operations and develop advanced data processing, analysis, and interface tools in order to fully realize MaNGA's exciting potential. Continuing in the Sloan tradition, MaNGA data products will be made publicly available, with the first release scheduled for Summer 2016.

    Full Text Available The interleukin (IL-6/IL-12 family cytokines have pleiotropic functions and play critical roles in multiple immune responses. This cytokine family has very unique characteristics in that they are composed of two distinct subunits forming a heterodimer and each cytokine and receptor subunit shares with each other. The members of this cytokine family are increasing; currently, there are more than 6 cytokines, including the tentatively named cytokines IL-Y (p28/p40, IL-12 (p35/p40, IL-23 (p19/p40, IL-27 p28/Epstein-Barr virus-induced protein 3 (EBI3, IL-35 (p35/EBI3, and IL-39 (p19/EBI3. This family of cytokines covers a very broad range of immune responses, including pro-inflammatory responses such as helper T (Th1, Th2, and Th17 to anti-inflammatory responses such as regulatory T (Treg cells and IL-10-producing Treg cells. IL-12 is the first member of this family, and IL-12, IL-23, and IL-27 are mainly produced by activated antigen-presenting cells such as dendritic cells and macrophages. IL-12 plays a critical role in the promotion of Th1 immune responses by inducing interferon-γ production to combat pathogens and malignant tumors. IL-23 induces IL-17 production and is necessary to maintain pathogenic Th17 cells that cause inflammatory and autoimmune diseases. IL-27 was initially reported to play a critical role in promotion of Th1 differentiation; however, subsequent studies revealed that IL-27 has broader stimulatory and inhibitory roles by inducing IL-10-producing Treg cells. IL-35 is produced by forkhead box P3+ Treg cells and activated B cells and has immunosuppressive functions to maintain immune tolerance. The most recently identified cytokine, IL-39, is produced by activated B cells and has pro-inflammatory functions. The cytokine tentatively named IL-Y seems to have anti-inflammatory functions by inhibiting Th1 and Th17 differentiation. In addition, individual cytokine subunits were also shown to have self-standing activities. Thus

    The role of IL-1 in susceptibility to Streptococcus pneumoniae infection was studied in mice deficient in genes of the IL-1 family [i.e. IL-1alpha-/-, IL-1beta-/-, IL-1alpha/beta-/- and IL-1R antagonist (IL-1Ra)-/- mice] following intra-nasal inoculation. Intra-nasal inoculation of S. pneumoniae of IL-1beta-/- and IL-1alpha/beta-/- mice displayed significantly lower survival rates and higher nasopharyngeal and lung bacterial load as compared with control, IL-1alpha-/- and IL-1Ra-/- mice. Treatment of IL-1beta-/- mice with rIL-1beta significantly improved their survival. A significant increase in blood neutrophils was found in control, IL-1alpha-/- and IL-1Ra-/- but not in IL-1beta-/- and IL-1alpha/beta-/- mice. Local infiltrates of neutrophils and relatively preserved organ architecture were observed in the lungs of IL-1alpha-/- and control mice. However, S. pneumoniae-infected IL-1beta-/-, IL-1alpha/beta-/- and IL-1Ra-/- mice demonstrated diffuse pneumonia and tissue damage. Altogether, all three isoforms contribute to protection against S. pneumoniae; our results point to differential role of IL-1alpha and IL-1beta in the pathogenesis and control of S. pneumoniae infection and suggest that IL-1beta has a major role in resistance to primary pneumococcal infection while the role of IL-1alpha is less important.

Quale mezzo migliore che la bici negli spostamenti casa-scuola, casa-lavoro? Le regioni del Sud Europa, come noto, scontano un grande ritardo culturale prima che infrastrutturale rispetto alla mobilità scolastica, lavorativa e turistica in bicicletta. Tutto ciò, nonostante le città scoppino di traffico e i ghiacciai si sciolgano per il surriscaldamento del pianeta dovuto alle emissioni di CO2. Per cercare di invertire la rotta, la Regione Puglia ha attivato e coordinato un partenariato internazionale composto, oltre che dallo stesso Ente anche dalle Regioni Campania, Calabria e Basilicata, delle Municipalità greche di Atene e Karditsa, dell’Ente del Turismo di Cipro e del Ministero dello Sviluppo Urbano di Malta, e ha concorso all’assegnazione di fondi del Programma Interreg IIIB Archimed (Arcipelago Mediterraneo messi a disposizione dal Ministero greco dell’Economia sulla Misura “Sviluppo di sistemi di trasporto efficaci e sostenibili”. L’obiettivo? Avviare il processo di pianificazione delle reti ciclabili a partire da uno studio di fattibilità degli itinerari ciclabili di media-lunga percorrenza delle retiEuroVelo® e Bicitalia® che attraversano i territori interessati. Tali itinerari di carattere transregionale e transnazionale, integrati con reti ciclabili locali e sovracomunali individuate all’interno delle aree vaste, possono contribuire a costruire quella necessaria rete di ciclovie per invogliare non più semplici appassionati della bicicletta, ma persone di tutte le età a muoversi sempre meno in auto e sempre più in bicicletta.

    2012-06-01

    Full Text Available L’intento del lavoro è di problematizzare alcuni aspetti, generalmente ritenuti emblematici, della relazione tra i litterati medievali e il libro – nelle sue declinazioni di Testo sacro, Libro della natura e auctoritates. L’impiego, come strumenti di lavoro, di concetti di recente elaborazione e di osservazioni di pensatori contemporanei sull’argomento, non è finalizzato ad attualizzare tale relazione, quanto piuttosto ad ampliare i punti di vista su di essa e a metterne alla prova la capacità di offrire originali spunti di riflessione. Le proposte teoriche di Jacques Derrida, Michel Foucault e Roland Barthes sono qui adoperate come esemplificazioni di un’interpretazione che ha storicamente reso quasi paradigmatico il modo di leggere dei docti, specialmente altomedievali. Tuttavia, alcune definizioni della Scrittura – il libro per eccellenza – proposte da questi ultimi, nonché la teorizzazione del suo quadruplice senso sembrano smussare la radicalità di queste osservazioni. Concetti quali “funzione-autore” di Foucault e “testo” di Barthes sono invece adottati per considerare all’interno di una diversa cornice teorica il confronto dei doctores, in particolare bassomedievali, con le cosiddette auctoritates. Nella visione ordinaria la reverenza nei confronti dell’autore, divino o umano, la ricerca e la riproposizione fedele di un significato univoco dell’opera aldilà dei segni, naturali o culturali, che lo veicolano costituiscono tratti tipici dell’atteggiamento dei lettori medievali. A fronte di questi aspetti, tuttavia, è possibile sottolinearne altri eterodossi e perlopiù trascurati, quali la rilevanza attribuita all’interpretazione, prassi ineludibile e da disciplinare, al ruolo del lettore e alla sua fruizione attiva e produttiva dei testi. The aim of the work is to problematize some aspects generally considered representative of the relationship between medieval savants and the book - in its variations

    2014-09-01

    In this study, we employed Flash- and Scratch-based multimedia by using a MaKey-MaKey-based task system to increase the motivation level of children with cerebral palsy to perform physical activities. MaKey MaKey is a circuit board that converts physical touch to a digital signal, which is interpreted by a computer as a keyboard message. In this study, we used conductive materials to control this interaction. This study followed single-case design using ABAB models in which A indicated the baseline and B indicated the intervention. The experiment period comprised 1 month and a half. The experimental results demonstrated that in the case of two kindergarten children with cerebral palsy, their scores were considerably increased during the intervention phrases. The developmental applications of the results are also discussed.

    The pathogenetic mechanisms underlying tendinopathy remain unclear, with much debate as to whether inflammation or degradation has the prominent role. Increasing evidence points toward an early inflammatory infiltrate and associated inflammatory cytokine production in human and animal models of tendon disease. The IL-21/IL-21R axis is a proinflammatory cytokine complex that has been associated with chronic inflammatory diseases including rheumatoid arthritis and inflammatory bowel disease. This project aimed to investigate the role and expression of the cytokine/receptor pair IL-21/IL-21R in human tendinopathy. We found significantly elevated expression of IL-21 receptor message and protein in human tendon samples but found no convincing evidence of the presence of IL-21 at message or protein level. The level of expression of IL-21R message/protein in human tenocytes was significantly upregulated by proinflammatory cytokines (TNFα/IL-1β) in vitro. These findings demonstrate that IL-21R is present in early human tendinopathy mainly expressed by tenocytes and macrophages. Despite a lack of IL-21 expression, these data again suggest that early tendinopathy has an inflammatory/cytokine phenotype, which may provide novel translational targets in the treatment of tendinopathy.

Increasing evidence points toward an early inflammatory infiltrate and associated inflammatory cytokine production in human and animal models of tendon disease. The IL-21/IL-21R axis is a proinflammatory cytokine complex that has been associated with chronic inflammatory diseases including rheumatoid arthritis and inflammatory bowel disease. This project aimed to investigate the role and expression of the cytokine/receptor pair IL-21/IL-21R in human tendinopathy. We found significantly elevated expression of IL-21 receptor message and protein in human tendon samples but found no convincing evidence of the presence of IL-21 at message or protein level. The level of expression of IL-21R message/protein in human tenocytes was significantly upregulated by proinflammatory cytokines (TNFα/IL-1β in vitro. These findings demonstrate that IL-21R is present in early human tendinopathy mainly expressed by tenocytes and macrophages. Despite a lack of IL-21 expression, these data again suggest that early tendinopathy has an inflammatory/cytokine phenotype, which may provide novel translational targets in the treatment of tendinopathy.

    The IL-23-IL-17 axis is emerging as a critical regulatory system that bridges the innate and adaptive arms of the immune system. Th17 cells have been linked to the pathogenesis of several chronic inflammatory and autoimmune diseases. However, the role of Th17 cells and IL-17 in various stages of atherogenesis remains poorly understood and is only beginning to be elucidated. While IL-17 is a predominantly proinflammatory cytokine, it has a pleiotropic function and it has been implicated both as an instigator in the pathogenesis of several inflammatory disorders as well as being protective in certain inflammatory disease models. Therefore, it is not surprising that the current literature is conflicting on the role of IL-17 during atherosclerotic lesion development. Various approaches have been used by several groups to discern the involvement of IL-17 in atherosclerosis. While one study found that IL-17 is protective against atherosclerosis, several other recent studies have suggested that IL-17 plays a proatherogenic role. Thus, the function of IL-17 remains controversial and awaits more direct studies to address the issue. In this review, we will highlight all the latest studies involving IL-17 and atherosclerosis, including both clinical and experimental research.

    The interleukin (IL)-1 family of cytokines comprises 11 members, including 7 pro-inflammatory cytokines (IL-1α, IL-1β, IL-18, IL-33, IL-36α, IL-36β,IL-36γ) and 4 anti-inflammatory cytokines (IL-1R antagonist (IL-1Ra), IL-36Ra, IL-37 and IL-38), and play central roles in mediating immune responses. In this study, we detected serum levels of IL-36 subfamily cytokines (including IL-36α, IL-36β, IL-36γ, IL-36Ra and IL-38), IL-37, IL-33 and aimed to investigate the roles of these cytokines in rheumatoid arthritis (RA) preliminarily. A total of 10 RA patients and 10 healthy controls (HCs) were involved in this study, we measured IL-36 subfamily cytokines, IL-37 and IL-33 levels in the serum of the experiment subjects by QAH-IL1F-1 assay. Clinical and laboratory data of the subjects were collected and analyzed by Spearman's rank test. Compared to that of HCs, IL-36α, IL-36β, IL-36Ra, IL-38 and IL-33 levels were significantly increased in RA patients. We also found RA patients with elevated IL-36Ra had a higher ESR and RF-IgM, and there was a positive correlation between increased IL-36α and CRP. Our study suggests that parts of the novel members of IL-1 family cytokines were involved in the pathogenesis of RA, and may provide a novel target for therapies of RA.

    Interleukin- (IL-) 35 and IL-37 are newly discovered immune-suppressing cytokines. They have been described in inflammatory diseases such as collagen-induced arthritis and asthma. However, their expressions in inflammatory bowel disease (IBD) patients have not been yet explored. Our aim was to evaluate serum and inflamed mucosal levels in IBD patients. In 20 ulcerative colitis (UC) patients, 7 Crohn's disease (CD) patients, and 15 healthy subjects, cytokine levels in serum were determined using ELISA and mucosal expression studies were performed by immunohistochemistry, quantitative real-time PCR, and Western blot. The results showed that serums IL-35 and IL-37 levels were significantly decreased in UC and CD patients compared with healthy subjects. The cytokines levels correlated inversely with UC activity. IL-35 was expressed in infiltrating immune cells while IL-37 in intestinal epithelial cells as well as inflammatory cells. IBD patients had significantly higher Ebi3, p35 (two subunits of IL-35), and IL-37b gene expressions; IL-35 and IL-37 protein expressions were higher in IBD patients compared with controls. The study showed that serums IL-35 and IL-37 might be potentially novel biomarkers for IBD. Intestinal IL-35 and IL-37 proteins are upregulated, suggesting that regulating the expression of the two cytokines may provide a new possible target for the treatment of IBD.

    Full Text Available Low vitamin D is involved in allergic asthma and rhinitis. IL-31 and IL-33 correlate with Th2-associated cytokines in allergic disease. We investigated whether low vitamin D is linked with circulating IL-31 and IL-33 in children with allergic disease of the airways. 25-Hydroxyvitamin D [25(OH Vit D], IL-31, and IL-33 plasma levels were measured in 28 controls (HC, 11 allergic rhinitis (AR patients, and 35 allergic asthma with rhinitis (AAR patients. We found significant lower levels of 25(OH Vit D in AR and in AAR than in HC. IL-31 and IL-33 plasma levels significantly increased in AAR than HC. IL-31 and IL-33 positively correlated in AR and AAR. 25(OH Vit D deficient AAR had higher levels of blood eosinophils, exacerbations, disease duration, and total IgE than patients with insufficient or sufficient 25(OH Vit D. In AAR 25(OH Vit D levels inversely correlated with total allergen sIgE score and total atopy index. IL-31 and IL-33 did not correlate with 25(OH Vit D in AR and AAR. In conclusion, low levels of 25(OH Vit D might represent a risk factor for the development of concomitant asthma and rhinitis in children with allergic disease of the airways independently of IL-31/IL-33 Th2 activity.

    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.

    The development of innovative technologies is steadily increasing the body of knowledge on molecules involved in physiological functions. Thus, several interleukins (ILs) have been identified and characterized in the past few years. Here, we detail the structural and functional characteristics of IL-34 to IL-38 with special attention to their involvement in inflammatory joint disease. IL-34 chiefly increases osteoclast activation and proliferation and therefore, it plays a direct role in bone destruction as seen in rheumatoid arthritis (RA). Regulatory T-cells (Tregs) express IL-35, which therefore exerts anti-inflammatory effects by restoring Treg suppressive capabilities and by inhibiting the Th17 pathway. IL-37 has anti-inflammatory effects mediated by a negative feedback loop that decreases the release of pro-inflammatory cytokines. IL-36 belongs to the IL-1 family and has three different forms. Although this cytokine has been chiefly studied in psoriasis and psoriatic arthritis, it also exerts pro-inflammatory effects in RA. The specific IL-36 antagonist, IL-36Ra binds to the IL-36 receptor, thereby, preventing signal transduction. Finally, IL-38 is a recently identified cytokine whose effect may resemble that of IL-36Ra as it binds to the IL-36 receptor and inhibits its effects, particularly the Th17-response. Although the exact roles for these cytokines awaits elucidation, the current improvements in our knowledge of the mechanisms that regulate chronic inflammatory conditions, such as RA may lead to the identification of new treatment targets.

    Full Text Available L’articolo indaga il nodo tra politica e vita che sembra stretto da Scurati nel Sopravvissuto sulla scorta della filosofia di Nietzsche; sembra cioè che egli assuma la “volontà di potenza” come impulso umano fondamentale. Ciò significa che il romanzo è intenzionato a tratteggiare l’ombra oscura che tale nodo proietta: non quella che porta all’affermazione dell'espansione vitale degli individui e delle collettività; ma quella che indica come i conflitti più significativi del nostro tempo avranno come oggetto e come campo di battaglia il corpo vivente dell'uomo. Il conflitto generazionale che Il sopravvissuto mette in scena non può che contenere un alto tasso di violenza, se è vero che l’istituzione scolastica non è qui in grado – come non lo sono l’istituzione psichiatrica e quella poliziesca – di opporsi all’espressione pura, e quasi caricaturale, della potenza di una gioventù tanto sublime quanto tradita nelle proprie aspirazioni alla pienezza vitale.

    È dalla più remota antichità che l’uomo si interroga sulla struttura dell’Universo e sulle leggi che lo governano. Ma il progresso compiuto all’inizio del XX secolo non ha paragoni rispetto a quello di tutti i secoli precedenti: nel 1915 fu formulata la relatività generale, indispensabile per inquadrare tutti i fenomeni cosmici e astrofisici; tra il 1920 e il 1930 furono determinate le reali dimensioni dell’Universo visibile e fu scoperta la sua costante espansione. La cosmologia ha poi fatto un grande salto di qualità a cavallo tra la fine del XX secolo e l’inizio del XXI, quando una serie di osservazioni ha confermato che: L’Universo è spazialmente "piatto", in seguito all’inflazione cosmica che, una frazione di secondo dopo il Big Bang, ne ha gonfiato le dimensioni di decine o centinaia di miliardi di volte. L’Universo è costituito al 70% da energia oscura e al 24% da materia oscura: la materia visibile, cioè stelle e galassie, rappresenta solo il 6% del totale. Attualmente l’espa...

    Objectives: To observe the plasmatic concentration of IL-6, IL-10 and IL-2 in the patient of chronic allergic rhinitis before and after acupuncture therapy. Methods: Cytokine levels were determined before and after treatment in 30 healthy volunteers (Group A) and 90 patients of chronic allergic rhinitis (Group B) with an increased plasma IL-10 level. Group B was then divided into 3 subgroups: 30 patients treated with real acupuncture (Group B1); 30 patients treated with sham acupuncture (Group B2); 30 non-treated patients (Group B3). Results: The allergic subjects of group B1, compared with controls, showed a significant reduction of IL-10 after a specific treatment with acupuncture (P<0.05). On the other hand, in those patients treated with sham acupuncture (B2) as well as in non-treated patients (B3), the IL-10 values remained high and unchanged. There was a statistically significant change in IL-2 values at 24 hours (P<0.05) after real acupuncture (Groups A, B1), however the values remained within normal ranges. The IL-6 do not change after therapy. Conclusion: The acupuncture treatment can reduce plasmatic level of IL-10 in chronic allergic rhinitis.

    Full Text Available Già il pensiero antico aveva identificato l’attitudine elementare al gioco come necessità primaria di incanalare l’energia fisica esuberante e disordinata, che caratterizza ogni creatura giovane. L’impulso all’agitazione, al movimento scomposto, eccessivo e improvvisato, si traduce in un infantile contatto col mondo basato su attività destrutturate e prive di scopo, in cui l’essenziale è il movimento stesso, l’azione in sé, ben più che non l’effettivo giungere a un risultato dell’azione. Proprio dall’obbligo di contenere e normare questo flusso incontrollato della fisicità infantile nascono, secondo Aristotele, le diverse forme di controllo pedagogico: «I fanciulli devono avere qualcosa da fare, e per questo è perfetto il sonaglio di Archita, che si dà ai più piccoli perché, occupati con esso, non rompano niente delle cose di casa: i bambini infatti non possono stare mai fermi. Per i più grandicelli, il sonaglio di Archita è l’educazione» (Politica, 8, 6, 1340b, 23-31. Ed è questa necessità incontenibile di movimento che già Platone aveva posto come origine prima non solo di ogni atto coreutico, ma anche della gioia stessa dello spettatore (Leggi, 2, 653d-657d: «Ogni creatura giovane non può star ferma col corpo o in silenzio con la voce, e sempre ha l’istinto di muoversi e gridare […] ma per noi anziani è più decoroso starli a guardare, i giovani, lieti del loro gioco e della festa, perché la nostra agilità ormai è perduta. E non è forse per nostalgia di quella agilità, che mettiamo in palio premi per chi meglio risveglia in noi il ricordo della giovinezza?».

    To explore the significance of interleukin-6 (IL-6) and IL-8 in the diagnosis of neonatal sepsis. This was a prospective study conducted between August 2014 and February 2015. A total of 140 neonates who were suspected infectious were enrolled and classified into a sepsis group (n=49) and a local infection group (n=91). Sixty-one neonates who were non-infectious served as the control group. Serum levels of IL-6 and IL-8 were measured before treatment and 3 days after treatment. The value of serum IL-6 and IL-8 for the diagnosis of neonatal sepsis was assessed by receiver operating characteristic (ROC) curve analysis. Before treatment, serum levels of IL-6 and IL-8 in the sepsis group were higher than those in the local infection and control groups (Psepsis group remained higher than that in the local infection and control groups (Pneonatal sepsis were 87.8%, 79.6% and 81.6% respectively; when the cut-off value of serum IL-8 was 54 pg/mL, the sensitivity, specificity and accuracy of serum IL-6 for the diagnosis of neonatal sepsis were 77.6%, 63.8% and 67.2% respectively. With the combination of serum IL-6 and IL-8 levels, the sensitivity, specificity and accuracy for the diagnosis of neonatal sepsis were 71.4%, 86.2% and 82.6% respectively. IL-6 and IL-8 participate in the inflammatory response and the serum levels of both vary with the severity of infection. The diagnostic value of IL-6 for neonatal sepsis is higher than IL-8. The combined detection of serum levels IL-6 and IL-8 may increase the accuracy of diagnosis of neonatal sepsis.

    Introduzione: il gioco d’azzardo ha profonde radici nella storia e nella cultura di ogni popolo. Si stima che circa l’80% della popolazione adulta nel nostro Paese giochi d’azzardo. Esso, pur rappresentando per la maggior parte di queste persone solo un innocuo passatempo, si trasforma talora in una vera e propria malattia (gambling compulsivo, con comportamenti che denotano forme estreme di rischio, sino a forme che portano alla distruzione della famiglia e persino della propria vita.

    Si tratta un disturbo poco conosciuto e spesso non diagnosticato. Infatti, benché sia largamente diffuso e comporti rilevanti costi umani e sociali, il gambling compulsivo solo di recente è stato incluso nelle classificazioni diagnostiche internazionali.

    Obiettivi: valutare l’impatto epidemiologico del gambling compulsivo (gioco d’azzardo patologico in una ASL/provincia.

    Materiali e metodi: è stato inviato un questionario ai 190 Medici di Medicina Generale della provincia di Grosseto (ASL 8, per raccogliere informazioni su: sistema di cura, numero di soggetti che si sono rivolti al proprio medico di famiglia per tale problema, eventuale coesistenza di problemi e comportamenti di dipendenza e di abuso (alcool, psicofarmaci, droghe illegali, ecc.

    Risultati: sono pervenuti 127 (pari al 66,8% questionari compilati. L’elaborazione dei dati è tuttora in corso.

    Conclusioni: dai risultati preliminari sembra emergere che il numero di persone che chiede aiuto al medico e al SSN, differentemente da quanto accade per i tossicodipendenti, è molto limitato e, quindi, intuitivamente poco indicativo della massa di soggetti realmente coinvolti dalla problematica studiata. Si discute del ruolo nella promozione della salute potenzialmente svolto dai Medici di Medicina Generale. Per quanto la tecnica di rilevazione appaia relativamente poco sensibile

Moreover, autophagy has a potentially pivotal role to play in the regulation of inflammatory responses. In particular, autophagy regulates endogenous inflammasome activators, as well as inflammasome components and pro-IL-1β. As a result, autophagy acts a key modulator of IL-1β and IL-18, as well as IL-1α, release.

    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...

    IL-17 is a cytokine produced by a newly identified T-cell subpopulation (THl7/THIL-17). It is a central mediator in inflammatory processes that connects T-cell stimulation with neutrophil mobilization. The role of IL-17 in the immune dysfunction after polytrauma is still not clarified. In a retrospective study, the systemic concentration of IL-17 and IL-6 of 71 polytraumatized patients were analyzed daily by enzyme-linked immunosorbent assay. The patients' collective consist of 55 men and 16 women (43 +/- 16 years; injury severity score, 33 +/- 13). In only 6% of the patients, an increase in systemic IL-17 was detected. In most patients (94%), no systemic IL-17 was detectable or the IL-17 concentrations in plasma were in the range of the healthy donor group. To identify a possible role of systemic IL-17 in the posttraumatic phase, the patients were divided into two groups. Group A (47 men, 15 women) consists of patients with IL-17 concentrations in the range of normal healthy donors. Group B (8 men, 1 woman) consists of patients with elevated (>45 pg ml(-1) on at least 3 consecutive days) systemic IL-17 concentrations. Three patients in group B showed highly increased systemic IL-17 concentrations (median, >200 pg mL(-1)). These patients were male and showed all blunt chest and abdominal trauma with lung contusion and pneumohemothorax. However, there was no conformity in other injury patterns, injury severity score, age, outcome, intensive care period, or clinical complications. After a period of 4 years, we were able to obtain a new blood sample from one patient with high IL-17 level. The systemic IL-17 value of this former patient was now less than the detection limit. However, stimulation of peripheral blood mononuclear cells from thlise patient revealed elevated numbers of cells with the capacity to produce IL-17 as determined by enzyme-linked immuno spot assay and flow cytometry compared with peripheral blood mononuclear cells obtained from current polytrauma

    Basophils are thought to play pivotal roles in allergic inflammation through rapid release of chemical mediators in addition to sustained production of Th2 cytokines, including IL-4. A newly identified cytokine, IL-33, has been recognized as one of the key cytokines enhancing Th2-balanced immune regulation through its receptor, ST2. The present study was conducted to elucidate whether IL-33 acts directly on, and affects the functions of, human basophils. Real-time PCR analysis showed that basophils express transcripts for ST2. The expression levels were significantly higher compared with eosinophils and neutrophils, and treatment with IL-33 significantly up-regulated basophil ST2 mRNA expression. Expressions of IL-4 and IL-13 mRNA were also up-regulated by IL-33, and there was also enhanced secretion of IL-4 protein. IL-33 increased the surface levels of basophil CD11b expression and enhanced basophil adhesiveness. Although IL-33 failed to directly induce degranulation or attract basophils, it exerted priming effects on basophils. It enhanced degranulation in response to IgE-crosslinking stimulus and also enhanced basophil migration toward eotaxin without changing surface CCR3. Also, IL-33 synergistically enhanced IL-4 production and CD11b expression by IL-3-stimulated basophils. Neutralization using Ab specific for ST2 significantly diminished the enhancing effects of IL-33 on both basophil CD11b expression and migration toward eotaxin, indicating that IL-33 signals via ST2 expressed on basophils. This study revealed that IL-33 potently regulates migration and activation of human basophils. IL-33 may be a key cytokine in the pathogenesis of Th2-dominant inflammation by acting not only on lymphocytes but also on effector cells such as basophils.

  16. Potential of IL-1, IL-18 and Inflammasome Inhibition for the Treatment of Inflammatory Skin Diseases

    Directory of Open Access Journals (Sweden)

    Gabriele Fenini

    2017-05-01

    Full Text Available In 2002, intracellular protein complexes known as the inflammasomes were discovered and were shown to have a crucial role in the sensing of intracellular pathogen- and danger-associated molecular patterns (PAMPs and DAMPs. Activation of the inflammasomes results in the processing and subsequent secretion of the pro-inflammatory cytokines IL-1β and IL-18. Several autoinflammatory disorders such as cryopyrin-associated periodic syndromes and Familial Mediterranean Fever have been associated with mutations of genes encoding inflammasome components. Moreover, the importance of IL-1 has been reported for an increasing number of autoinflammatory skin diseases including but not limited to deficiency of IL-1 receptor antagonist, mevalonate kinase deficiency and PAPA syndrome. Recent findings have revealed that excessive IL-1 release induced by harmful stimuli likely contributes to the pathogenesis of common dermatological diseases such as acne vulgaris or seborrheic dermatitis. A key pathogenic feature of these diseases is IL-1β-induced neutrophil recruitment to the skin. IL-1β blockade may therefore represent a promising therapeutic approach. Several case reports and clinical trials have demonstrated the efficacy of IL-1 inhibition in the treatment of these skin disorders. Next to the recombinant IL-1 receptor antagonist (IL-1Ra Anakinra and the soluble decoy Rilonacept, the anti-IL-1α monoclonal antibody MABp1 and anti-IL-1β Canakinumab but also Gevokizumab, LY2189102 and P2D7KK, offer valid alternatives to target IL-1. Although less thoroughly investigated, an involvement of IL-18 in the development of cutaneous inflammatory disorders is also suspected. The present review describes the role of IL-1 in diseases with skin involvement and gives an overview of the relevant studies discussing the therapeutic potential of modulating the secretion and activity of IL-1 and IL-18 in such diseases.

  17. IL-25, IL-33 and TSLP receptor are not critical for development of experimental murine malaria

    Full Text Available IL-25, IL-33 and TSLP, which are produced predominantly by epithelial cells, can induce production of Th2-type cytokines such as IL-4, IL-5 and/or IL-13 by various types of cells, suggesting their involvement in induction of Th2-type cytokine-associated immune responses. It is known that Th2-type cytokines contribute to host defense against malaria parasite infection in mice. However, the roles of IL-25, IL-33 and TSLP in malaria parasite infection remain unclear. Thus, to elucidate this, we infected wild-type, IL-25−/−, IL-33−/− and TSLP receptor (TSLPR−/− mice with Plasmodium berghei (P. berghei ANKA, a murine malaria strain. The expression levels of IL-25, IL-33 and TSLP mRNA were changed in the brain, liver, lung and spleen of wild-type mice after infection, suggesting that these cytokines are involved in host defense against P. berghei ANKA. However, the incidence of parasitemia and survival in the mutant mice were comparable to in the wild-type mice. These findings indicate that IL-25, IL-33 and TSLP are not critical for host defense against P. berghei ANKA.

    Interleukin (IL)-21 has recently been shown to play a vital role in the development of many autoimmune diseases. Our study is designed to investigate the alteration and possible function of IL-21 in the development of an experimental autoimmune uveitis (EAU) model. EAU was induced in B10.RIII mice by subcutaneous injection of interphotoreceptor retinoid-binding protein (IRBP) 161-180 emulsified with complete Freund's adjuvant (CFA) and evaluated by clinical and histopathologic observation. IL-21 and IL-21R mRNA expressions in cells of draining lymph node (DLN) and spleen in EAU and control mice were determined by reverse transcription-PCR. The frequencies of interleukin-21 receptor positive cells were also examined using flow cytometry. IL-17 levels in the supernatant of the cell culture upon IL-21 stimulation were assayed by enzyme-linked immunosorbent assay. Results showed that EAU was successfully induced by IRBP161-180. Expression of IL-21 mRNA was significantly increased in cells of DLN and spleen in EAU compared with recovery phase mice and normal controls. IL-21R was also found upregulated in DLN and spleen cells of EAU mice by reverse transcription-PCR and flow cytometry. Cells in EAU cultured with IL-21 combined with transforming growth factor-beta induced increased production of IL-17. The findings revealed that increased IL-21 and IL-21R expression may be involved in the development of EAU, possibly by promoting IL-17 secretion.

    Mantle plumes originate from boundary layers below the upper mantle. Their surface expressions as hotspot tracks have been linked to voluminous outpourings of lava in the form of large igneous provinces. The Galapagos hotspot has been active since ~90 Ma and the oldest lavas of its associated submarine ridge have been dated to ~14 Ma, subducting at the Middle America Trench, off Costa Rica. The Galapagos plume head magmatic production is preserved as the Caribbean Large Igneous Province (CLIP). A series of 15-65 Ma accreted Galapagos paleo-ridges and islands/seamounts are accreted in the Pacific coast of Costa Rica and Panama. One of these accreted terranes, the Quepos block on the west coast of Costa Rica is an ancient, ~65 Ma Galapagos island. Olivine phenocrysts from Quepos picrites have elevated Ni and low Ca and Mn and Fe/Mn indicative of a dominant pyroxenite source component while CLIP samples are dominated by a peridotite source. The mantle potential temperature (max) of the plume changed from ~1650 to ~1550 C at 65 Ma. This change correlates with the first appearance of the pyroxenite component and an EMII signature (Northern Galapagos Domain) in the Galapagos plume. A relatively dense pyroxenite component may provide a mechanism for the change in Tp due to its effect on the plume's bouyancy. Alternatively, the pyroxenite component was diluted by high peridotite melt fraction during the massive production of the CLIP.

    Time to maturity is a critical trait in sorghum (Sorghum bicolor) breeding, as it determines whether a variety can be grown in a particular cropping system or ecosystem. Understanding the nucleotide variation and the mechanisms of molecular evolution of the maturity genes would be helpful for breeding programs. In this study, we analyzed the nucleotide diversity of Ma3, an important maturity gene in sorghum, using 252 cultivated and wild sorghum materials from all over the world. The nucleotide variation and diversity were analyzed based both on race- and usage-based groups. We also sequenced 12 genes around the Ma3 gene in 185 of these materials to search for a selective sweep and found that purifying selection was the strongest force on Ma3, as low nucleotide diversity and low-frequency amino acid variants were observed. However, a very special mutation, described as ma3R, seemed to be under positive selection, as indicated by dramatically reduced nucleotide variation not only at the loci but also in the surrounding regions among individuals carrying the mutations. In addition, in an association study using the Ma3 nucleotide variations, we detected 3 significant SNPs for the heading date at a high-latitude environment (Beijing) and 17 at a low-latitude environment (Hainan). The results of this study increases our understanding of the evolutionary mechanisms of the maturity genes in sorghum and will be useful in sorghum breeding.

    Full Text Available L’articolo esamina il caso della Pedia de Cyro di Boiardo dimostrando come il volgarizzamento raffrontato all’Historia de Cyri vita, la traduzione latina di Poggio Bracciolini della Ciropedia di Senofonte, offra un osservatorio privilegiato sul modo di lavorare del conte di Scandiano: poiché il testo è stato lasciato ad uno stadio intermedio tra l’abbozzo e la limatura definitiva, è stato possibile rintracciarvi i luoghi dell’intervento boiardesco e la sua riscrittura in chiave moderna. Il volgarizzamento presenta una narrazione meno vicina all’impianto per lo più dialogico dell’originale, mantenuto prevalentemente anche in Poggio, e più sciolta, che pone al centro del racconto l’azione. La riscrittura di interi passi permette di precisare il modo in cui Boiardo è intervenuto sulla primitiva traduzione del suo segretario, amplificandola con dovizia di particolari a partire da stilemi boccacciani, per trasformare il tono epico della vicenda in timbro cavalleresco e patetico. Si sono presentati alcuni casi significativi dell’azione versoria e dell’elaborazione letteraria del conte, proponendone sempre l’analisi linguistico-retorica, a dimostrazione di come la riscrittura boiardesca abbia eliminato il lato epico, ma anche divertente e lepido della Ciropedia, mantenuto da Poggio, a favore di un’atmosfera più patetica e moraleggiante, maggiormente consona all’interesse del duca di Ferrara. This article examines how Boiardo’s vernacular translation of the Pedia de Cyro offers insight into the Count of Scandiano’s modus operandi: whilst being somewhere between the draft and polishing stage, the Boiardo text reveals various degrees of translation. The vernacular translation presents a narrative far from the more dialogical structure of the original work and reproposed by Poggio Bracciolini in his translation. In fact, Boiardo’s work appears to be more light and free and places action at its core. Moreover, the

    An interferon (IFN) signature is involved in the pathogenesis of primary Sjögren's syndrome (pSS), but whether the signature is type 1 or 2 remains controversial. Mouse models and genetic studies suggested the involvement of T helper 1 and type 2 IFN pathways. Likewise, polymorphisms of interleukin 12A gene (IL-12A), which encodes for IL-12p35, have been associated with pSS. IL-12p35 subunit is shared by 2 heterodimers, IL-12 and IL-35. To confirm the genetic association of IL-12A polymorphism and pSS and elucidate the involvement of the IL-12/IL-35 balance in pSS by functional studies. The genetic study involved 673 patients with pSS from 2 French pSS cohorts and 585 healthy French controls. Functional studies were performed on sorted monocytes, stimulated or not. IL-12A mRNA and IL-12 and IL-35 protein levels were assessed by qRT-PCR and by ELISA and a multiplex kit for IL-35 and IL-12, respectively. We confirmed the association of the IL-12A rs485497 polymorphism and pSS and found an increased serum protein level of IL-12p70 in pSS patients carrying the risk allele (p=0.016). Serum level of IL-12p70 was greater in patients than controls (p=0.0001), especially patients with more active disease (p=0.05); conversely IL-35 level was decreased in patients (p=0.0001) especially in patients with a more active disease (p=0.05). In blood cellular subsets, both IL-12p35 and EBI-3 mRNAs were detected only in B cells with a trend toward a lower level among pSS patients. Our findings emphasize the involvement of the IL-12/IL-35 balance in the pathogenesis of pSS. Serum IL-35 level was associated with low disease activity, in contrast to serum IL-12p70 level, which was rather associated with a more active disease. Copyright © 2017. Published by Elsevier Inc.

    IL-35 is a cytokine of the IL-12 family, existing as a heterodimer of IL-12p35 and Ebi3. IL-35 has anti-inflammatory properties and is produced by regulatory T cells in humans and mice, where it is required for optimal suppression of immune responses. Distinct from other IL-12 cytokines, the expression of IL-35 has not been described in antigen-presenting cells. In view of the immune-regulatory properties of IL-35, we investigated the expression, regulation, and function of IL-12p35 and Ebi3 in human monocyte-derived dendritic cells and tolerogenic DCs (tolDCs). These tolDCs do not produce IL-12p70 or the homodimer IL-12p40. We demonstrate that tolDCs completely lack transcriptional expression of IL-12p40. However, tolDCs maintain mRNA expression of IL-12p35 and Ebi3. Using intracellular flow cytometry and Western blot analysis, we show that tolDCs produce Ebi3 and IL-12p35, and both can be enhanced upon stimulation with IFN-γ, LPS, or CD40L. tolDCs supernatants have the capacity to suppress T-cell activation. Using IL12A silencing, we demonstrate that IL-12p35 is required for tolDCs to reach their full suppressive potential. Taken together, our results indicate that tolDCs produce IL-35, providing an additional novel mechanism by which tolDCs elicit their tolerogenic potential.

    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.

Interleukin-22-/- mice had a mildly impaired ability to expel the worm and this correlated with reduced or delayed induction of TH2 immunity as measured by splenic and mesenteric lymph node production of IL-4, IL-5 and IL-13 and intestinal Muc-2 mRNA and goblet cell hyperplasia; in contrast, IL-25 increased in the small intestine of IL-22-/- mice 8 and 12 days post-infection compared to WT mice. In vitro experiments revealed that H. diminuta directly evoked epithelial production of IL-25 that was inhibited by recombinant IL-22. Also, IL-10 and markers of regulatory T cells were increased in IL-22-/- mice that displayed less DNBS (3 mg, ir. 72h-induced colitis. Wild-type mice infected with H. diminuta were protected from colitis, as were infected IL-22-/- mice and the latter to a degree that they were almost indistinguishable from control, non-DNBS treated mice. Finally, treatment with anti-IL-25 antibodies exaggerated DNBS-induced colitis in IL-22-/- mice and blocked the anti-colitic effect of infection with H. diminuta. Thus, IL-22 is identified as an endogenous brake on helminth-elicited TH2 immunity, reducing the efficacy of expulsion of H. diminuta and limiting the effectiveness of the anti-colitic events mobilized following infection with H. diminuta in a non-permissive host.

    Full Text Available Aims. In the present study, we aimed to assess the concentrations of IL-13 and IL-17 in serum of patients with early rheumatoid arthritis (eRA, the investigation of correlation between the concentrations of these cytokines and disease activity score, and the concentration of some autoantibodies and the evaluation of the utility of IL-13 and -17 concentration measurements as markers of disease activity. Materials and Methods. Serum samples were collected from 30 patients and from 28 controls and analysed parameters. Results. The serum concentrations of IL-13, IL-17, anti-CCP, and IgM-RF were statistically significantly higher in patients with eRA, compared to the controls. IL-13 concentrations in the severe and moderate groups with eRA were statistically higher than in the mild and control groups. Also, in the case of IL-17, serum concentrations increased proportionally with the disease activity of eRA. We observe that concentrations of IL-13 and -17 did not correlate with autoantibodies. IL-17 concentration significantly positively correlated with CRP, while IL-13 concentration significantly negatively correlated with CRP. Disease activity score, DAS28, was strongly positively correlated with levels of ESR and weakly positively correlated with concentrations of anti-RA33 autoantibodies. IL-13 has a higher diagnostic utility than IL-17, CRP, ESR, IgM-RF, and anti-CCP as markers of disease activity. Conclusions. The presence of higher IL-13 and IL-17 serum levels in patients, compared with those of controls, confirms that these markers, found with high specificity, might be involved in the pathogenesis of eRA. IL-13 and IL-17 might be of better usefulness in the prediction of eRA activity status than IgM-RF and anti-CCP.

    Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterized by the development of autoantibodies to nuclear antigens and inflammatory responses mediated by multiple cytokines. Although previous studies have determined clinical associations between SLE and the anti-inflammatory cytokines IL-10 and IL-37, their role in the disease, or their potential as biomarkers, remains unclear. We examined serum levels of IL-10 and IL-37 in a large cohort of SLE patients, with detailed longitudinal clinical data. We demonstrate a statistically significant association of serum IL-10 with disease activity, with higher levels in active compared to inactive disease. High first visit IL-10 was predictive of high subsequent disease activity; patients with IL-10 in highest quartile at first visit were 3.6 times more likely to have active disease in subsequent visits. Serum IL-37 was also higher in SLE patients compared to control, and was strongly associated with Asian ethnicity. However, IL-37 was not statistically significantly associated with disease activity. IL-37 was significantly reduced in patients with organ damage but this association was attenuated in multivariable analysis. The data suggest that IL-10, but not IL-37, may have potential as a biomarker predictive for disease activity in SLE. PMID:27708376

    Enhanced IL-31 expression in skin biopsies is present in allergic contact dermatitis (ACD). IL-33 expression is induced in keratinocytes and in skin of ACD patients. This overexpression is present in both allergic and irritant conditions. The aim of this work was to test the systemic involvement of IL-31 and IL-33 in ACD. IL-31 levels were significantly higher in patients than in controls. IL-33 serum levels, on the contrary, were similar in patients and controls. This work shows a possible systemic involvement of IL-31 and the absence of a systemic involvement of IL-33 in ACD. IL-31 levels do not seem related to the allergen involved, and did not change on the strength of the allergen involved. More likely, IL-31 levels are related to the itch. IL-33, instead, is secreted from damaged or inflamed tissue and might function as an early warning system at the site of skin damage. In the future, IL-31 could be a possible therapeutic target of all pruritic skin diseases resistant to conventional therapies.

Materials and Methods. The whole peripheral blood samples were collected from 30 CP patients and 25 healthy controls. Flow cytometry was used to test the (IL-17A+ and/or IL-17F+ Th17 expression level. Recombinant human IL-23 (rhIL-23 was used to detect Th17 differentiation and expansion. Correlation coefficient analysis between Th17 expression level and clinical parameters was analyzed by SPSS software. Results. Flow cytometry results showed that IL-17A+IL-17F− and IL-17A−IL-17F+ Th17 were both increased in CP group than in HC group (P < 0.01, while, under recombinant human IL-23 (rhIL-23 stimulation, the number of IL-17A+IL-17F− Th17 cells was significantly increased in both CP and HC groups (P < 0.01. Interestingly, IL-17A−IL-17F+ Th17 cells were only increased in CP group after rhIL-23 stimulation. Additionally, correlation coefficient analysis showed significant correlation between IL-17A+IL-17F− Th17 cell and attachment loss or probing depth (P < 0.05. Conclusions. This study indicates that both the IL-17A+IL-17F− and IL-17A−IL-17F+ Th17 cells may be involved in pathogenesis of periodontitis. The role of these Th17 cells in the disease pathogenesis needs to be further investigated.

    Full Text Available Inflamm-aging indicates the chronic inflammatory state resulting from increased secretion of proinflammatory cytokines and mediators such as IL-6 in the elderly. Our principle objective was to identify cell types that were affected with aging concerning IL-6 secretion in the murine model. We compared IL-6 production in spleen cells from both young and aged mice and isolated several types of cells from spleen and investigated IL-6 mRNA expression and protein production. IL-6 protein productions in cultured stromal cells from aged mice spleen were significantly high compared to young mice upon LPS stimulation. IL-6 mRNA expression level of freshly isolated stromal cells from aged mice was high compared to young mice. Furthermore, stromal cells of aged mice highly expressed IL-6 mRNA after LPS injection in vivo. These results suggest that stromal cells play a role in producing IL-6 in aged mice and imply that they contribute to the chronic inflammatory condition in the elderly.

    Cytokines are essential mediators of immune response and inflammatory reactions. Patients with chronic renal failure (CRF) commonly present with abnormalities of immune function related with impaired kidney function and the accumulation of uremic toxins in addition to bioincompatibility of dialyzer membranes. During a hemodialysis (HD) session, cytokines are released mainly by monocytes activated by endotoxin-type compounds in dialyzer fluid,complement factors and direct contact with dialyzer membrane. The study included 15 CRF patients, aged 36.4 ± 2.9 years, on regular HD maintenance therapy for mean 68 ± 10 months and 15 healthy controls. It was designed to assess serum levels of a panel of inflammatory cytokines: IL-1β, IL-2, IL-6, IL-8 and TNF-α in CRF patients on regular maintenance HD before, 20, 60 and 240 minutes of a single HD session in parallel with C-reactive protein (CRP) as an additional parameter. CRP concentration was increased in HD patients when compared with healthy controls. The concentrations of IL-1, IL-6, IL-8 and TNF-α were increased, whereas the serum level of IL-2 was not altered during a single HD session.

  11. IL-6 and mouse oocyte spindle.

    Full Text Available Interleukin 6 (IL-6 is considered a major indicator of the acute-phase inflammatory response. Endometriosis and pelvic inflammation, diseases that manifest elevated levels of IL-6, are commonly associated with higher infertility. However, the mechanistic link between elevated levels of IL-6 and poor oocyte quality is still unclear. In this work, we explored the direct role of this cytokine as a possible mediator for impaired oocyte spindle and chromosomal structure, which is a critical hurdle in the management of infertility. Metaphase-II mouse oocytes were exposed to recombinant mouse IL-6 (50, 100 and 200 ng/mL for 30 minutes and subjected to indirect immunofluorescent staining to identify alterations in the microtubule and chromosomal alignment compared to untreated controls. The deterioration in microtubule and chromosomal alignment were evaluated utilizing both fluorescence and confocal microscopy, and were quantitated with a previously reported scoring system. Our results showed that IL-6 caused a dose-dependent deterioration in microtubule and chromosomal alignment in the treated oocytes as compared to the untreated group. Indeed, IL-6 at a concentration as low as 50 ng/mL caused deterioration in the spindle structure in 60% of the oocytes, which increased significantly (P<0.0001 as IL-6 concentration was increased. In conclusion, elevated levels of IL-6 associated with endometriosis and pelvic inflammation may reduce the fertilizing capacity of human oocyte through a mechanism that involves impairment of the microtubule and chromosomal structure.

    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

Using SiMA we were able to identify typical migration profiles of the chemoattractants IL-8, fMLP, and LTB4 , the effect of the matrices FN versus HEM as well as the response to different medications, that is, Prednisolone induced a change of direction of migrating neutrophils in FN but no such effect was observed in human placental matrix. In addition, neutrophils of asthmatic individuals showed an increased proportion of cells migrating toward the vehicle. With the SiMA platform we presented a simplified but yet flexible platform for cost-effective tracking and quantification of neutrophil migration. The introduced method is based on a simple microscopic video stage, standardized, commercially available, µ-fluidic migration chambers and automated image analysis, and track validation software. © 2017 International Society for Advancement of Cytometry. © 2017 International Society for Advancement of Cytometry.

    Interleukin 4 (IL-4) can suppress delayed-type hypersensitivity reactions (DTHRs), including organ-specific autoimmune diseases in mice and humans. Despite the broadly documented antiinflammatory effect of IL-4, the underlying mode of action remains incompletely understood, as IL-4 also promotes IL-12 production by dendritic cells (DCs) and IFN-γ–producing TH1 cells in vivo. Studying the impact of IL-4 on the polarization of human and mouse DCs, we found that IL-4 exerts opposing effects on the production of either IL-12 or IL-23. While promoting IL-12–producing capacity of DCs, IL-4 completely abrogates IL-23. Bone marrow chimeras proved that IL-4–mediated suppression of DTHRs relies on the signal transducer and activator of transcription 6 (STAT6)-dependent abrogation of IL-23 in antigen-presenting cells. Moreover, IL-4 therapy attenuated DTHRs by STAT6- and activating transcription factor 3 (ATF3)-dependent suppression of the IL-23/TH17 responses despite simultaneous enhancement of IL-12/TH1 responses. As IL-4 therapy also improves psoriasis in humans and suppresses IL-23/TH17 responses without blocking IL-12/TH1, selective IL-4–mediated IL-23/TH17 silencing is promising as treatment against harmful inflammation, while sparing the IL-12–dependent TH1 responses.

    IL-25 is a newly discovered member of IL-1 7 family,with immunomodulatory functions.IL-25 may participate in type 2 immune response,to promote IL-4,IL-5,IL-9,IL-1 3 and other cytokines se-cretion. It also binds with IL-1 7A and IL-1 7RA receptor,inhibits joint cartilage formation. By stimulating the release of nitric oxide and proinflammatory cytokines IL-6,IL-8 production,it can participate in autoimmune inflammatory diseases.%IL-25是新近发现的IL-17家族成员,具有免疫调节功能。IL-25可参与2型免疫反应,促进IL-4、IL-5、IL-9、IL-13等细胞因子分泌,也可与IL-17A及其受体IL-17RA结合,亦能抑制关节软骨的形成,刺激一氧化氮的释放以及前炎症因子IL-6、IL-8的产生,进而参与自身免疫炎症疾病。

    Objective To explore the roles of cytokines in the pathogenesis of hemorrhagic fever with renal syndrome(HFRS). Methods Double-antibody sandwich ELISA was used to determine serum interleukin (IL)-6, urine tumor necrosis factor (TNF), IL-6 and IL-8 levels in 56 patients with HFRS. Results Serum IL-6, urine TNF, IL-6 and IL-8 concentrations in HFRS patients were significantly higher than those in control group, respectively (P<0.001). The concentrations increased at fever stage, then continued to increase during hypotension stage and peaked at oliguria stage. The concentrations of serum IL-6, urine TNF, IL-6 and IL-8 increased in accord with the severity of the disease and differed greatly among different types of the disease. Serum IL-6 had remarkable relationships with serum specific antibodies. It was positively related to serum β2-microglobulin (β2-MG), blood ureanitrogen (BUN) and creatinine (Cr). Significant positive relationships were also found both between urine IL-6 and TNF, and between IL-6 and IL-8 (r=0.5768, P<0.05; r=0.3760, P<0.01). Conclusion TNF, IL-6 and IL-8 activated during the course of the disease. IL-6 is associated with the immunopathological lesions caused by the hyperfunction of humoral immune response. IL-6, IL-8 and TNF are involved in the renal immune impairment. Determining them might, in certain extent, be used in predicting the prognosis and outcome of patients with HFRS.

    From NCBI Gene: This gene encodes a cytokine that acts as a growth and differentiation factor for both B cells and eosinophils. The encoded cytokine plays a major role in the regulation of eosinophil formation, maturation, recruitment and survival. The increased production of this cytokine may be related to pathogenesis of eosinophil-dependent inflammatory diseases. This cytokine functions by binding to its receptor, which is a heterodimer, whose beta subunit is shared with the receptors for interleukine 3 (IL3) and colony stimulating factor 2 (CSF2/GM-CSF). This gene is located on chromosome 5 within a cytokine gene cluster which includes interleukin 4 (IL4), interleukin 13 (IL13), and CSF2 . This gene, IL4, and IL13 may be regulated coordinately by long-range regulatory elements spread over 120 kilobases on chromosome 5q31. [provided by RefSeq, Jul 2013

    Although interleukin (IL) 17 has been extensively characterized, the function of IL-17F, which has an expression pattern regulated similarly to IL-17, is poorly understood. We show that like IL-17, IL-17F regulates proinflammatory gene expression in vitro, and this requires IL-17 receptor A, tumor necrosis factor receptor–associated factor 6, and Act1. In vivo, overexpression of IL-17F in lung epithelium led to infiltration of lymphocytes and macrophages and mucus hyperplasia, similar to observations made in IL-17 transgenic mice. To further understand the function of IL-17F, we generated and analyzed mice deficient in IL-17F or IL-17. IL-17, but not IL-17F, was required for the initiation of experimental autoimmune encephalomyelitis. Mice deficient in IL-17F, but not IL-17, had defective airway neutrophilia in response to allergen challenge. Moreover, in an asthma model, although IL-17 deficiency reduced T helper type 2 responses, IL-17F–deficient mice displayed enhanced type 2 cytokine production and eosinophil function. In addition, IL-17F deficiency resulted in reduced colitis caused by dextran sulfate sodium, whereas IL-17 knockout mice developed more severe disease. Our results thus demonstrate that IL-17F is an important regulator of inflammatory responses that seems to function differently than IL-17 in immune responses and diseases. PMID:18411338

    Full Text Available À partir d’un corpus issu de la « nouvelle vague de films d’émigration », cet article se propose d’analyser le regard que porte le cinéma égyptien sur l’émigration économique massive de ses contemporains. En quoi ces représentations cinématographiques diffèrent-elles des discours scientifiques, médiatiques ou littéraires ? Au-delà de leur rêve de réussite matérielle et de la crainte de l’aliénation culturelle, les migrants ne contribuent-ils pas à interroger sans cesse les fondements de l’imaginaire national ? Après avoir brièvement décrit le corpus, nous esquisserons une cartographie des imaginaires géographiques de la migration au cinéma, paradoxalement plutôt orientée vers l’Occident, alors que la majorité des Égyptiens se trouvent dans le Golfe. Le cinéma, tout comme la littérature, produit une vision très pessimiste de l’émigration, dans une critique tant des pays de réception que de la société égyptienne. Assiste-t-on pour autant à l’émergence d’un cinéma transnational, c’est-à-dire, qui envisage notamment la possibilité d’une identité à la fois d’ici et de là-bas ?

  2. Decoding asthma: translating genetic variation in IL33 and IL1RL1 into disease pathophysiology.

    Asthma is a complex disease that results from the interaction between genetic predisposition and environmental factors. Recently, genome-wide association studies have identified a number of genes that significantly contribute to asthma. Two of these genes, IL33 and IL-1 receptor-like 1 (IL1RL1), act in one signal transduction pathway. IL33 encodes a cytokine released on damage of cells, whereas IL1RL1 encodes part of the IL-33 receptor complex. Recent progress made in functional studies in human subjects and mouse models of allergic airway disease indicate a central role of IL-33 signaling in driving TH2 inflammation, which is central to eosinophilic allergic asthma. Here, IL-33 acts on cells of both the adaptive and innate immune systems. Very recently, a novel population of IL-33-responsive innate immune cells, the type 2 innate lymphoid cells, was found to produce hallmark TH2 cytokines, such as IL-5 and IL-13. The relevance of these cells for asthma is underscored by the identification of retinoic acid-related orphan receptor α(RORA), the gene encoding the transcription factor critical for their differentiation, as another asthma gene in genome-wide association studies. This review describes the mechanisms through which genetic variation at the IL33 and IL1RL1 loci translates into increased susceptibility for asthma. We propose that genetic variation associated with asthma at the IL33 and IL1RL1 loci can be dissected into independent signals with distinct functional consequences for this pathway that is central to asthma pathogenesis.

    2002-09-01

    Full Text Available In uno scritto recente ho sostenuto la tesi che la politica ottimale per il Mezzogiorno non è il laissez faire, né l’intervento diretto dello stato nell’economia, ma un intervento pubblico, anche “massiccio”, realizzato mediante leggi generali e astratte, che per loro natura sono di tipo non discrezionale.La necessità di un intervento generalizzato a favore di una zona meno sviluppata si giustifica con l’esistenza delle “diseconomie esterne”, che frenano lo sviluppo di tutte le imprese che operano in quella zona. Ha destato, perciò, in me meraviglia leggere l’articolo scritto contemporaneamente da Beniamino Moro (2001 e pubblicato nel numero 215 di questa rivista, che raggiunge lo stesso risultato con argomentazioni di segno opposto.

    Full Text Available Partendo dall’analisi del criticismo proposta da Simmel, si può dire che Kant abbia infranto l’armonia tra essere e pensare sul piano metafisico e quella tra virtù e felicità sul piano morale. Ciò non significa abbandonare definitivamente la teoria di un sistema delle nostre facoltà, ma piuttosto porre questo tema al centro pensandolo come compito. Sotto questo aspetto la Critica del Giudizio può essere letta come il tentativo di riannodare i fili spezzati: da questo testo emerge in modo peculiare il problema della natura. La natura non è più intesa come oggetto sottoposto alla legislazione dell’intelletto, bensì come elemento chiave che dà la regola all’arte.

  13. MaRGEE: Move and Rotate Google Earth Elements

    Science.gov (United States)

    Dordevic, Mladen M.; Whitmeyer, Steven J.

    2015-12-01

    Google Earth is recognized as a highly effective visualization tool for geospatial information. However, there remain serious limitations that have hindered its acceptance as a tool for research and education in the geosciences. One significant limitation is the inability to translate or rotate geometrical elements on the Google Earth virtual globe. Here we present a new JavaScript web application to "Move and Rotate Google Earth Elements" (MaRGEE). MaRGEE includes tools to simplify, translate, and rotate elements, add intermediate steps to a transposition, and batch process multiple transpositions. The transposition algorithm uses spherical geometry calculations, such as the haversine formula, to accurately reposition groups of points, paths, and polygons on the Google Earth globe without distortion. Due to the imminent deprecation of the Google Earth API and browser plugin, MaRGEE uses a Google Maps interface to facilitate and illustrate the transpositions. However, the inherent spatial distortions that result from the Google Maps Web Mercator projection are not apparent once the transposed elements are saved as a KML file and opened in Google Earth.

    Full Text Available Aims. The influence of interleukin-10 (IL-10 and interleukin-18 (IL-18 polymorphisms on tacrolimus pharmacokinetics had been described in liver and kidney transplantation. The expression of cytokines varied in different kinds of transplantation. The influence of IL-10 and IL-18 genetic polymorphisms on the pharmacokinetic parameters of tacrolimus remains unclear in lung transplantation. Methods. 51 lung transplant patients at Shanghai Pulmonary Hospital were included. IL-18 polymorphisms (rs5744247 and rs1946518, IL-10 polymorphisms (rs1800896, rs1800872, and rs3021097, and CYP3A5 rs776746 were genotyped. Dose-adjusted trough blood concentrations (C/D ratio, mg/kg body weight in lung transplant patients during the first 4 postoperative weeks were calculated. Results. IL-18 rs5744247 allele C and rs1946518 allele A were associated with fast tacrolimus metabolism. Combined analysis showed that the numbers of low IL-18 mRNA expression alleles had positive correlation with tacrolimus C/D ratios in lung transplant recipients. The influence of IL-18 polymorphisms on tacrolimus C/D ratios was observed in CYP3A5 expresser recipients, but not in CYP3A5 nonexpresser recipients. No clinical significance of tacrolimus C/D ratios difference of IL-10 polymorphisms was found in our data. Conclusions. IL-18 polymorphisms may influence tacrolimus elimination in lung transplantation patients.

    As a chronic inflammatory condition, psoriasis results from an interaction between genetic and immunologic factors in a predisposing environment. In spite of compelling evidence for the role of T cells and cytokines in psoriasis, interleukin (IL)-10 and IL-22 have not been sufficiently investigated. To assess the serum levels of IL-10 and IL-22 in patients with psoriasis compared to healthy controls. A total of 28 patients with psoriasis were compared with 28 age and sex-matched healthy subjects. Psoriasis Area and Severity Index (PASI) criteria were used to measure the severity of the disease. Serum levels of IL-10 and IL-22 were measured in both groups and compared. The mean serum level of IL-10 was 89.5±18.7 in patients compared to 117.2±23.4 pg/ml in the controls (p=0.36). Also, serum level of IL-22 was 284.1±49.7 in patients versus 425.4±82.8 pg/ml in control group (p=0.17). There was a significant direct correlation between levels of IL-10 and IL-22 in patients group (p=0.0005). The clinical severity of psoriasis was significantly correlated with high levels of IL-22 (ppsoriasis.

    Interleukin-7 (IL-7), a cytokine produced by stromal cells, is required for thymic development and peripheral homeostasis of most major subsets of T cells. We examined whether regulatory T (Treg) cells also required the IL-7 pathway by analyzing IL-7Ralpha(-/-) mice. We observed a striking reduction in cells with the Treg surface phenotype (CD4, CD25, GITR (glucocorticoid-induced tumor necrosis factor [TNF]-like receptor), CD45RB, CD62L, CD103) or intracellular markers (cytotoxic T-lymphocyte-associated antigen-4, CTLA-4, and forkhead box transcription factor 3, Foxp3). Foxp3 transcripts were virtually absent in IL-7Ralpha(-/-) lymphoid tissues, and no Treg cell suppressive activity could be detected. There are 2 known ligands for IL-7Ralpha: IL-7 itself and thymic stromal lymphopoietin (TSLP). Surprisingly, mice deficient in IL-7 or the other chain of the TSLP receptor (TSLPR) developed relatively normal numbers of Treg cells. Combined deletion of IL-7 and TSLP receptor greatly reduced Treg cell development in the thymus but was not required for survival of mature peripheral Treg cells. We conclude that Treg cells, like other T cells, require signals from the IL-7 receptor, but unlike other T cells, do not require IL-7 itself because of at least partially overlapping actions of IL-7 and TSLP for development of Treg cells.

    interleukin (IL)-24 and -29 are novel cytokines, produced by immune cells in response to microbial antigens. The functions of these cytokines in the reproductive system are unknown. We examined the expression pattern of IL-24 and IL-29 in human fetal membranes from preterm and term births and in in vitro in response to microbial antigens. fetal membranes collected from cesarean sections at term (normal, not in labor) were placed in culture for 48 h. These membranes were then stimulated with bacterial lipopolysaccharide (LPS) or viral antigen poly-inosinic and cytidylic acid (polyIC) for an additional 24 h. Amniotic fluids (AF) and fetal membranes were also collected from preterm and term deliveries. IL-24 and IL-29 expressions were studied by RT-PCR. ELISA documented culture media and AF cytokine concentrations. IL-24 and IL-29 expressions were seen in cultured fetal membranes regardless of stimulation. Expressions were also found in preterm and term labor membranes, but not in non-labor tissues at term. IL-24 concentrations were higher after LPS stimulation whereas IL-29 concentrations were higher after polyIC-stimulation. AF analysis did not detect either of the cytokines either preterm or term. this is the first study to report IL-24 and IL-29 expressions in human fetal membranes. Higher concentrations of these cytokines in response to distinct infectious stimuli suggest different pathways for fetal immune response during infection.

    The inflammasome is a cytoplasmic multiprotein complex that promotes proinflammatory cytokine maturation in response to host- and pathogen-derived signals. Missense mutations in cryopyrin (NLRP3) result in a hyperactive inflammasome that drives overproduction of the proinflammatory cytokines IL-1β and IL-18, leading to the cryopyrin-associated periodic syndromes (CAPS) disease spectrum. Mouse lines harboring CAPS-associated mutations in Nlrp3 have elevated levels of IL-1β and IL-18 and closely mimic human disease. To examine the role of inflammasome-driven IL-18 in murine CAPS, we bred Nlrp3 mutations onto an Il18r-null background. Deletion of Il18r resulted in partial phenotypic rescue that abolished skin and visceral disease in young mice and normalized serum cytokines to a greater extent than breeding to Il1r-null mice. Significant systemic inflammation developed in aging Nlrp3 mutant Il18r-null mice, indicating that IL-1 and IL-18 drive pathology at different stages of the disease process. Ongoing inflammation in double-cytokine knockout CAPS mice implicated a role for caspase-1-mediated pyroptosis and confirmed that CAPS is inflammasome dependent. Our results have important implications for patients with CAPS and residual disease, emphasizing the need to explore other NLRP3-mediated pathways and the potential for inflammasome-targeted therapy.

  7. IL-4 function can be transferred to the IL-2 receptor by tyrosine containing sequences found in the IL-4 receptor alpha chain.

    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.

    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.

    Interleukin (IL)-36α, IL-36β and IL-36γ are expressed highly in skin and are involved in the pathogenesis of psoriasis, while the antagonists IL-36Ra or IL-38, another potential IL-36 inhibitor, limit uncontrolled inflammation. The expression and role of IL-36 cytokines in rheumatoid arthritis (RA) and Crohn's disease (CD) is currently debated. Here, we observed that during imiquimod-induced mouse skin inflammation and in human psoriasis, expression of IL-36α, γ and IL-36Ra, but not IL-36β and IL-38 mRNA, was induced and correlated with IL-1β and T helper type 17 (Th17) cytokines (IL-17A, IL-22, IL-23, CCL20). In mice with collagen-induced arthritis and in the synovium of patients with RA, IL-36α, β, γ, IL-36Ra and IL-38 were all elevated and correlated with IL-1β, CCL3, CCL4 and macrophage colony-stimulating factor (M-CSF), but not with Th17 cytokines. In the colon of mice with dextran sulphate sodium-induced colitis and in patients with CD, only IL-36α, γ and IL-38 were induced at relatively low levels and correlated with IL-1β and IL-17A. We suggest that only a minor subgroup of patients with RA (17-29%) or CD (25%) had an elevated IL-36 agonists/antagonists ratio, versus 93% of patients with psoriasis. By immunohistochemistry, IL-36 cytokines were produced by various cell types in skin, synovium and colonic mucosa such as keratinocytes, CD68⁺ macrophages, dendritic/Langerhans cells and CD79α⁺ plasma cells. In primary cultures of monocytes or inflammatory macrophages (M1), IL-36β and IL-36Ra were produced constitutively, but IL-36α, γ and IL-38 were produced after lipopolysaccharide stimulation. These distinct expression profiles may help to explain why only subgroups of RA and CD patients have a potentially elevated IL-36 agonists/antagonists ratio.

    More and more urgent, especially of late, is the need to plan nationwide, integrated strategy to prevent and control hydrogeological crises. And great efforts have been made in this direction by the National Environmental Protection Agency (ANPA) which, starting in 1998 (year of the so-called Sarno law) tasked itself with reducing and preventing the hydrogeological risk by monitoring the structural works defending the soil. However, there are still too many dramatic events in Italy due, indeed, to exceptional rainfalls but at times also to problems in the hydraulic and zoning systems of the afflicted areas, to incorrect occupation of the land or to a lack of protective work. Making fundamental the technical and scientific support that the ANPA-ARPA system offers in this context to national, regional and local authorities. [Italian] Si fa sempre piu' pressante, soprattutto negli ultimi tempi, la necessita' di pianificare strategie integrate di intervento sul territorio per la prevenzione e il controllo delle crisi idrogeologiche. E grande e' l'impegno dimostrato in questo senso dall'Agenzia Nazionale per la Protezione dell'Ambiente che, a partire dal 1998, anno della cosidetta Legge Sarno, si e' assunta il compito di ridurre e prevenire il rischio idrogeologico attraverso il monitoraggio delle opere strutturali di difesa del suolo. Si contano purtroppo pero' ancora troppi eventi drammatici nel nostro Paese, dovuti si' alle eccezionali precipitazioni atmosferiche, ma talvolta anche a problemi di sistemazione idraulico-urbanistica nelle aree colpite, alla scorretta occupazione del territorio o alla mancanza di opere di salvaguardia. Risulta quindi fondamentale il supporto tecnico e scientifico che il sistema ANPA-ARPA offre, in questo contesto, alle Autorita' nazionali, regionali e locali.

    Ogni persona colloca i fatti ordinandoli lungo una freccia psicologica del tempo e così distingue tra il passato e il futuro. La distinzione è netta, poiché i fatti disposti nel passato non sono modificabili, mentre quelli che si verificheranno sono, in linea di massima, solo prevedibili: non possiamo esercitare alcuna influenza sugli eventi passati, ma possiamo nutrire la speranza di condizionare, almeno in parte, quelli che non si sono ancora verificati. La questione della freccia psicologica è collegata alla circostanza per cui l'individuo ha coscienza d'essere sempre situato in un «qui e ora», così da ricordare solo certi fatti del passato e da non avere alcuna memoria del futuro. Questo stato di cose, pur manifestandosi in modo del tutto naturale, presenta però analogie con quel particolare stato di cose grazie al quale ciascuno di noi parla di oggetti che si trovano «in alto» o «in basso», sulla base di una distinzione che non è poi dissimile da quella che riguarda il «prima» e il «dopo�...

    2013-06-01

    Full Text Available Il presente studio ipotizza un’affinità tra Caravaggio e Teofilo Folengo, argomentando che la pittura del primo presenta analogie estetiche e etiche con la produzione in latino maccheronico del secondo. Il Baldus costituisce un tipico esempio di quella che Genette definirà come «parodia seria»: attraverso il rovesciamento e la irrisione beffarda Folengo ingaggia tenzone contro l’arte paludata e il travisamento dei valori cristiani. Non si tratta qui di stabilire un’influenza di Folengo su Caravaggio, bensì un’analogia, in virtù di un filo di congiunzione ideale, la cui presumibilità viene corroborata anche dal substrato biografico-culturale e da comune spirito religioso. Sia in Folengo che in Caravaggio sono stati individuati i caratteri di un certo modo della cultura lombarda di essere “contro” al punto che il duo Folengo-Caravaggio sembra epitomizzare l’antitesi al decorum curialcortigianesimo di Castiglione e Raffaello. Il Cristo-paradosso costituisce la vera fonte ispiratrice per entrambi. La comparazione tra due arti deve tenere conto dei diversi strumenti espressivi, e questo costituirà uno dei soggetti di riflessione nel testo. Se l’ipotesi della consentaneità viene ragionevolmente difesa, perché non individuare una componente maccheronica anche nell’arte di Caravaggio? Agli storici d’arte, tuttavia, decidere se si possa considerare il maccheronico come categoria pittorica

    Jiang, Tao; Zhou, Caicun; Ren, Shengxiang

    2016-06-01

    Interleukin-2 (IL-2) is one of the key cytokines with pleiotropic effects on immune system. It has been approved for the treatment of metastatic renal cell carcinoma and metastatic melanoma. Recent progress has been made in our understanding of IL-2 in regulating lymphocytes that has led to exciting new directions for cancer immunotherapy. While improved IL-2 formulations might be used as monotherapies, their combination with other anticancer immunotherapies, such as adoptive cell transfer regimens, antigen-specific vaccination, and blockade of immune checkpoint inhibitory molecules, for example cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) and programmed death 1 (PD-1) mono-antibodies, would held the promise of treating metastatic cancer. Despite the comprehensive studies of IL-2 on immune system have established the application of IL-2 for cancer immunotherapy, a number of poignant obstacles remain for future research. In the present review, we will focus on the key biological features of IL-2, current applications, limitations, and future directions of IL-2 in cancer immunotherapy.

    2013-01-01

    Bone has a high capacity for self-renewal and repair. Prolonged local secretion of interleukin 1β (IL-1β), however, is known to be associated with severe bone loss and delayed fracture healing. Since induction of bone resorption by IL-1β may not sufficiently explain these pathologic processes, we investigated, in vitro, if and how IL-1β affects migration of multipotent mesenchymal stromal cells (MSC) or osteoblasts. We found that homogenous exposure to IL-1β significantly diminished both nondirectional migration and site-directed migration toward the chemotactic factors platelet-derived growth factor (PDGF)-BB and insulinlike growth factor 1 (IGF-1) in osteoblasts. Exposure to a concentration gradient of IL-1β induced an even stronger inhibition of migration and completely abolished the migratory response of osteoblasts toward PDGF-BB, IGF-1, vascular endothelial growth factor A (VEGF-A) and the complement factor C5a. IL-1β induced extracellular signal-regulated kinases 1 and 2 (ERK1/2) and c-Jun N-terminal kinases (JNK) activation and inhibition of these signaling pathways suggested an involvement in the IL-1β effects on osteoblast migration. In contrast, basal migration of MSC and their migratory activity toward PDGF-BB was found to be unaffected by IL-1β. These results indicate that the presence of IL-1β leads to impaired recruitment of osteoblasts which might influence early stages of fracture healing and could have pathological relevance for bone remodeling in inflammatory bone disease.

    Czabotar, P E; Holland, J; Sanderson, C J

    1999-10-22

    In mice there are two forms of the beta chain used in the IL3 receptor system, betacom and betaIL3. betacom is used by the IL3, IL5 and GM-CSF receptors whereas betaIL3 is only used in the IL3 receptor. In this work an assay was developed to identify residues of beta1L3 that restrict IL5 activity. It was found that such residues reside within the 2nd CRM of the molecule. Furthermore, when residues in the betaIL3 B'-C' loop were replaced with betacom sequence a form of betaIL3 was produced that was able to respond to IL5. This region is also responsible for IL3 binding to betaIL3 in the absence of alpha chain. It is therefore an important structural motif of betacom and betaIL3 responsible for both ligand interaction and specificity.

    To effectively repair or replace damaged tissues, it is necessary to design three dimensional (3D) extracellular matrix (ECM) mimicking scaffolds with tunable biomechanical properties close to the desired tissue application. In the present work, gelatin methacrylate (GelMA) and dextran glycidyl methacrylate (DexMA) with tunable mechanical and biological properties were utilized to prepared novel bicomponent polymeric hydrogels by cross-linking polymerization using photoinitiation. We controlled the degree of substitution (DS) of glycidyl methacrylate in DexMA so that they could obtain relevant mechanical properties. The results indicated that copolymer hydrogels demonstrated a lower swelling ratio and higher compressive modulus as compared to the GelMA. Moreover, all of the hydrogels exhibited a honeycomb-like architecture, the pore sizes decreased as DS increased, and NIH-3T3 fibroblasts encapsulated in these hydrogels all exhibited excellent viability. These characteristics suggest a class of photocrosslinkable, tunable mechanically copolymer hydrogels that may find potential application in tissue engineering and regenerative medicine applications.

    Glioma is one of the most aggressive and most common tumors of the central nervous system (CNS) in humans. The exact causes of glioma are not well known, but evidence suggests the involvement of genetic factors in addition to environmental risk factors. The present study aimed to determine whether polymorphisms in IL-10-1082A/G, IL-12p40 1188C/A, and IL-13+2044G/A (rs20541) are associated with the incidence of glioma in Iraqi patients. Ninety-six patients with different grades of glioma and 40 apparently healthy individuals were recruited. A blood sample and genomic DNA were collected from all subjects. The amplification refractory mutation system and sequence-specific primer polymerase chain reaction (PCR) were used for genotyping of IL-10-1082A/G and IL-12p40 1188C/A, respectively; whereas, the IL-13+2044G/A was detected by DNA sequencing after amplification of the genes by PCR. All SNPs were within Hardy-Weinberg equilibrium and each appeared in three genotypes in patients and controls. In IL-10-1082A/G, these genotypes frequencies were AA (75%), AG (22.93%) and GG (2.07%) in patients as compared to similar frequencies (62.5%), (27.5%) and (10%) respectively, in controls. The variant IL-12p40 1188C/A genotype was AA (72.92%), AC (23.96%), and CC (3.13%%) in patients as compared to 65%, 30%, and 5%, respectively, in controls. The frequencies of IL-13+2044G/A genotypes (GG, GA, and AA) were 89.58%, 9.37%, and 1.04% among patients versus 47.5%, 32.5% and 20%, respectively, among controls. These results suggest a protective role of mutant alleles G and A in IL-10-1082A/G and IL-13+2044G/A against gliomas. Further studies with more rigorous parameter designs will be needed to confirm the current findings.

    The use of cytokines from the IL-2 family (also called the common γ chain cytokine family) such as interleukin (IL)-2, IL-7, IL-15, and IL-21 to activate the immune system of cancer patients is one of the most important areas of current cancer immunotherapy research. The infusion of IL-2 at low or high doses for multiple cycles in patients with metastatic melanoma and renal cell carcinoma was the first successful immunotherapy for cancer proving that the immune system could completely eradicate tumor cells under certain conditions. The initial clinical success observed in some IL-2-treated patients encouraged further efforts focused on developing and improving the application of other IL-2 family cytokines (IL-4, IL-7, IL-9, IL-15, and IL-21) that have unique biological effects playing important roles in the development, proliferation, and function of specific subsets of lymphocytes at different stages of differentiation with some overlapping effects with IL-2. IL-7, IL-15, and IL-21, as well as mutant forms or variants of IL-2, are now also being actively pursued in the clinic with some measured early successes. In this review, we summarize the current knowledge on the biology of the IL-2 cytokine family focusing on IL-2, IL-15 and IL-21. We discuss the similarities and differences between the signaling pathways mediated by these cytokines and their immunomodulatory effects on different subsets of immune cells. Current clinical application of IL-2, IL-15 and IL-21 either as single agents or in combination with other biological agents and the limitation and potential drawbacks of these cytokines for cancer immunotherapy are also described. Lastly, we discuss the future direction of research on these cytokines, such as the development of new cytokine mutants and variants for improving cytokine-based immunotherapy through differential binding to specific receptor subunits.

    Full Text Available Malnutrition is one of the health issues in developing countries. The most commonly found malnutrition is the marasmus type. Infection in marasmus patient is the main cause of morbidity and mortality in developing countries. In marasmus, there is a decrease in protein level such as cysteine which is one of the glutathione forming components that plays a significant role in immune system. In malnutrition, there is a disturbance of lymphocyte in the form of down-regulation of type 1 cytokine (IL-2 and IFN-γ and up-regulation of type 2 cytokine (IL-4 and IL-10. IL-2 is needed for the development of regulatory T produced by thymus and for NK cell cytotoxicity which plays a role in infection process, while IL-10 inhibits activation of lymphocyte T so the cellular immunity reaction ends. Several studies about the relationship between cysteine, IL-2, and IL-10 have been done in malnutrition-patients, but there is no study focusing on patients with marasmus. This study is to find out the relationship between cysteine, IL-2, and IL-10 in patients with marasmus type malnutrition. This study was an observational analytic study using cross-sectional design consisting of 20 children with marasmus type malnutrition and 20 well-nourished children treated in Saiful Anwar Hospital Malang. The cysteine, IL-2, and IL-10 level then measured using Elisa method. Normality and the various test were done. The Pearson correlation test was done to find out the relationship between cysteine and IL-2 level, cysteine and IL-10 level, and IL-2 and IL-10. The standard of cysteine and IL-2 level in children with marasmus is significantly lower than the control group, which was 1.616 ± 1.039 vs 3.298 ± 0.519 pg/mL; p = 0.000 dan 12.38±4.94 vs. 16.58 ± 4.80 pg/mL; p = 0.010, respectively. IL-10 in children with marasmus was significantly higher than control group (19.08± 5.93 vs 10.46 ± 3.90 pg/mL; p = 0.000. The cysteine level was positively correlated to the IL-2 level

    IL-25 or IL-17E is a member of IL-17 cytokine family and has immune-modulating activities. The role of IL-25 in maintaining lipid metabolic homeostasis remains unknown. We investigated the effects of exogenous IL-25 or deficiency of IL-25 on hepatic lipid accumulation. IL-25 expression was examined in paraffin-embedded tissue sections of liver from patients or in the livers from mice. Mouse model of steatosis was induced by feeding a high-fat diet (HFD). Extent of steatosis as well as expression of cytokines, key enzymes for lipid metabolic pathways, markers for Kupffer cells/macrophages, and lipid droplet (LD) proteins, were analyzed. Our results show that hepatic steatosis in mice was accompanied by increased LD proteins, but decreased IL-25 in the liver. Decreased hepatic IL-25 was also observed in patients with fatty liver. Administration of IL-25 to HFD-fed wild-type mice led to a significant improvement in hepatic steatosis. This effect was associated with increased expression of IL-13, development of alternatively activated Kupffer cells/macrophages, and decreased expression of LD proteins in the liver. In contrast, administration of IL-25 to HFD-fed mice deficient in STAT6 or IL-13 had no effects. In addition, stimulation of primary hepatocytes with IL-13, but not IL-25, resulted in downregulation of LD proteins. Finally, mice deficient in IL-25 had exacerbated hepatic lipid accumulation when fed the HFD. These data demonstrate that dysregulated IL-25 expression contributes to lipid accumulation, whereas exogenous IL-25 protects against hepatic steatosis through IL-13 activation of STAT6. IL-25 and IL-13 are potential therapeutic agents for hepatic steatosis and associated pathologies.

    Chronic rhinosinusitis with nasal polyps (CRSwNP) is one of the most frequently encountered chronic nasal diseases with a significant impact on patient quality of life. The aim of our study was therefore to investigate the association between the POSTN, IL-4, and IL-13 gene expression and the nasal polyp development. The objective of this study was to determine differential expression of POSTN, IL-4, and IL-13 genes in the mucosa and polyps of 63 patients with CRSwNP and 23 chronic rhinosinusitis (CRS) without nasal polyps (CRSsNP) when compared with patients with nasal septum deviation (n=18) who were used as controls. The expression level was investigated using reverse transcription-polymerase chain reaction assays in the polyp tissue and the mucosa of paranasal sinus collected while undergoing functional endoscopic sinus surgery. Expression of the mRNAs of all three genes, IL-4, IL-13, and POSTN, was significantly greater in the paired tissues of CRS patients with NPs or without NPs than in control subjects, with highest levels of POSTN and IL-13 seen in CRSwNP. An increased level of POSTN, IL-4, and IL-13 gene expression may be related to the development of chronic rhinosinusitis with nasal polyps, but polyp formation seemed to be associated especially with POSTN and IL-13 expression.

  9. IL-18 induces airway hyperresponsiveness and pulmonary inflammation via CD4+ T cell and IL-13.

    Full Text Available IL-18 plays a key role in the pathogenesis of pulmonary inflammatory diseases including pulmonary infection, pulmonary fibrosis, lung injury and chronic obstructive pulmonary disease (COPD. However, it is unknown whether IL-18 plays any role in the pathogenesis of asthma. We hypothesized that overexpression of mature IL-18 protein in the lungs may exacerbate disease activities of asthma. We established lung-specific IL-18 transgenic mice on a Balb/c genetic background. Female mice sensitized- and challenged- with antigen (ovalbumin were used as a mouse asthma model. Pulmonary inflammation and emphysema were not observed in the lungs of naïve transgenic mice. However, airway hyperresponsiveness and airway inflammatory cells accompanied with CD4(+ T cells, CD8(+ T cells, eosinophils, neutrophils, and macrophages were significantly increased in ovalbumin-sensitized and challenged transgenic mice, as compared to wild type Balb/c mice. We also demonstrate that IL-18 induces IFN-γ, IL-13, and eotaxin in the lungs of ovalbumin-sensitized and challenged transgenic mice along with an increase in IL-13 producing CD4(+ T cells. Treatment with anti-CD4 monoclonal antibody or deletion of the IL-13 gene improves ovalbumin-induced airway hyperresponsiveness and reduces airway inflammatory cells in transgenic mice. Overexpressing the IL-18 protein in the lungs induces type 1 and type 2 cytokines and airway inflammation, and results in increasing airway hyperresponsiveness via CD4(+ T cells and IL-13 in asthma.

    High-affinity IgG autoantibodies (aAb) to IL-1alpha are among the most frequently found aAb to cytokines in humans. To establish an animal model with aAb to IL-1alpha, we immunised mice with recombinant murine IL-1alpha. Unprimed and Bacille Calmette-Guérin (BCG)-primed BALB/cA mice were vaccinated...... in mice by vaccination with recombinant murine IL-1alpha conjugated to PPD. Studies of the effects of IL-1alpha aAb in such animals may help clarify the importance of naturally occurring IL-1alpha aAb in humans and permit the evaluation of future therapies with cytokine aAb in patients...... with IL-1alpha coupled to purified protein derivative of tuberculin (PPD). Both unprimed and primed animals developed IgG aAb to IL-1alpha. These aAb persisted at high levels more than 100 days after vaccination and did not cross-react with murine IL-1beta. The induced anti-IL-1alpha aAb inhibited binding...

  11. The role of interleukin-5 (IL-5 in vivo: studies with IL-5 deficient mice

    Full Text Available Eosinophil recruitment is a characteristic feature of a number of pathological conditions and was the topic of the recent International Symposium on allergic inflammation, asthma, parasitic and infectious diseases (Rio de Janeiro, June 3-5, 1996. Since interleukin5 (IL5 is believed to regulate the growth, differentiation and activation of eosinophils (Coffman et al. 1989, Sanderson 1992, the role of eosinophils and IL5 are closely linked. Although IL5 specifically regulates eosinophilia in vivo and this is its most well established activity, it is becoming clear that IL5 also has other biological effects. The recent derivation of an IL5 deficient mouse (Kopf et al. 1996, provides a model for exploring not only the role of IL5 and eosinophils but also other novel activities of IL5. Of note is that although the IL5 deficient mice cannot elicit a pronounced eosinophilia in response to inflammatory stimulation following aeroallergen challenge or parasite infection they still produce basal levels of eosinophils that appear to be morphologically and functionally normal. However, the basal levels of eosinophils appear insufficient for normal host defence as IL5 deficiency has now been shown to compromise defence against several helminth infections. In addition, IL5 deficient mice appear to have functional deficiencies in B-1 B lymphocytes and in IgA production.

    B cells from myasthenia gravis (MG) patients with autoantibodies (Aab) against acetylcholine receptor (AChR), muscle-specific kinase (MuSK) or with no detectable Aab were investigated as cytokine producing cells in this study. B cells were evaluated for memory phenotypes and expressions of IL-10, IL-6 and IL-12A. Induced productions of IL-10, IL-6, IL-12p40, TNF-α and LT from isolated B cells in vitro were measured by immunoassays. MG patients receiving immunosuppressive treatment had higher proportions of memory B cells compared with healthy controls and untreated patients. With CD40 stimulation MG patients produced significantly lower levels of IL-10, IL-6. With CD40 and B cell receptor stimulation of B cells, TNF-α production also decreased in addition to these cytokines. The lower levels of these cytokine productions were not related to treatment. Our results confirm a disturbance of B cell subpopulations in MG subgroups on immunosuppressive treatment. B cell derived IL-10, IL-6 and TNF-α are down-regulated in MG, irrespective of different antibody productions. Ineffective cytokine production by B cells may be a susceptibility factor in dysregulation of autoimmune Aab production.

    Pyometra is a serious bacterial infection of the uterus affecting female dogs and manifests as an accumulation of pus in the uterine lumen. The aim of the study was to assess changes in serum interleukin (IL)-6 and IL-10 concentrations in bitches with pyometra undergoing ovariohysterectomy. Blood samples were collected from healthy bitches (controls) and bitches with pyometra before surgery, and 3 and 10 days after ovariohysterectomy. Before surgery, bitches with pyometra had significantly higher serum concentrations of IL-6 and IL-10 than the controls. After surgery, the serum concentration of IL-6 and IL-10 decreased significantly. In healthy dogs, the concentration of IL-6 and IL-10 showed a significant increase 3 days after surgery followed by a decrease on day 10. An increase in serum concentrations of IL-6 and IL-10 was present before surgery in bitches with pyometra and 3 days after ovariohysterectomy in healthy controls. Concentrations decreased after ovariohysterectomy and/or proper healing, suggesting that these cytokines can be useful for assessment of the postoperative period in bitches.

    The pathogenesis of spondyloarthritis (SpA) involves activation of the innate immune system, inflammation and new bone formation. The two cytokines 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 SpA patients compared with healthy controls (HCs) by 57% and 83%, respectively (both p<0.0001). The Toll like receptor 4 induced secretion of the two cytokines was greater in SpA peripheral blood mononuclear cells (PBMCs) compared with HC PBMCs. IL-20 and IL-24 increased the production of monocyte chemo attractant protein-1 by activated SpA synovial fluid monocytes, decreased the production of dickkopf-1 by SpA fibroblast-like synovial cells and induced mineralization in human osteoblasts. Taken together, our findings indicate disease-aggravating functions of IL-20 and IL-24 in SpA. This article is protected by copyright. All rights reserved.

    Full Text Available Abstract Background Allergic bronchopulmonary aspergillosis occurs in 7–10% of cystic fibrosis (CF and 1–2% of asthmatic patients. HLA-DR restriction and increased sensitivity to IL-4 stimulation have been proposed as risk factors in these populations. Objective We examined for the presence of IL-4 receptor alpha chain (IL-4Rα single nucleotide polymorphisms (SNPs in ABPA and whether these accounted for increased sensitivity to IL-4 stimulation. Methods One extracellular (ile75val and four cytoplasmic IL-4Rα SNPs were analyzed in 40 CF and 22 asthmatic patients and in 56 non-ABPA CF and asthmatic patients. Sensitivity to IL-4 stimulation was measured by induction of CD23 expression on B cells. Results IL-4Rα SNPs were observed in 95% of ABPA patients. The predominant IL-4Rα SNP was the extracellular IL-4Rα SNP, ile75val, observed in 80% of ABPA patients. Conclusion The presence of IL-4Rα SNPs, principally ile75val, appears to be a genetic risk for the development of ABPA.

  16. Photodynamic therapy affects the expression of IL-6 and IL-10 in vivo

    Photodynamic therapy (PDT), which can effectively destroy malignant tissue, also induces a complex immune response which potentiates anti-tumor immunity, but also inhibits skin contact hypersensitivity (CHS) and prolongs skin graft survival. The underlying mechanisms responsible for these effects are poorly understood, but are likely to involve meditation by cytokines. We demonstrate in a BALB/c mouse model that PDT delivered to normal and tumor tissue in vivo causes marked changes in the expression of cytokines interleukin (IL)-6 and IL-10. IL-6 mRNA and protein are rapidly and strongly enhanced in the PDT treated EMT6 tumor. Previous studies have shown that intratumoral injection of IL- 6 or transduction of the IL-6 gene into tumor cells can enhance tumor immunogenicity and inhibit tumor growth in experimental murine tumor systems. Thus, PDT may enhance local anti-tumor immunity by up-regulating IL-6. PDT also results in an increase in IL-10 mRNA and protein in the skin. The same PDT regime which enhances IL-10 production in the skin has been shown to strongly inhibit the CHS response. The kinetics of IL-10 expression coincide with the known kinetics of PDT induced CHS suppression and we propose that the enhanced IL-10 expression plays a role in the observed suppression of cell mediated responses seen following PDT.

    2014-12-01

    Full Text Available This article has chiefly to do with a Greek concept especially subject to overlap in meaning: pneûma. Translated into Latin as ‘spiritus’, pneûma is a unique term doubtlessly accounting for the handful of ideas grounding Western tradition. Pneûma’s former significations look to be substantially different to the major one with which the term has come down and stands for the time being. Hence, it seems worthwhile enquiring into its origins in ancient scientific literature. In order to do so, the papyrus called Anonymus Londinensis, a master piece in the History of Medicine, will be examined and put alongside Aristotle’s biological views. Attention is therefore focused on the occurrences of pneûma in the papyrus, its different meanings when contrasted to cognate terms like ‘phŷsa’ or ‘air’, as well as the special way that very term may have displayed by the different physicians reported in the document.El presente artículo versa sobre un término griego especialmente sujeto a la polisemia: pneûma. Traducido al latín como ‘spiritus’, pneûma es uno de los conceptos que, sin duda, se encuentra en la base y ha conformado la tradición especulativa occidental. Dado que los primeros significados de pneûma parecen substancialmente distintos al sentido mayoritario y general por el que se lo tiene en la actualidad, parece conveniente indagar su uso en la literatura científica griega. Para ello se estudia su empleo en el seno de una de las obras claves de la Historia de la Medicina, el llamado papiro Anonymus Londinensis, y se contrasta con la biología griega del s. IV a.C. tal y como se encuentra en los Parva Naturalia de Aristóteles. La atención, por tanto, se centra en el uso y significado del término en dicho papiro, su significado particular cuando se lo compara con algunos términos afines como ‘phŷsa’ o ‘aire’, así como el modo especial con el que lo usan los diferentes médicos de los que el papiro da

  18. Oral Escherichia coli colonization factor antigen I fimbriae ameliorate arthritis via IL-35, not IL-27.

    A Salmonella therapeutic expressing enterotoxigenic Escherichia coli colonization factor Ag I (CFA/I) fimbriae protects against collagen-induced arthritis (CIA) by eliciting two regulatory T cell (Treg) subsets: TGF-β-producing Foxp3(-)CD39(+)CD4(+) T cells and IL-10-producing Foxp3(+)CD39(+)CD4(+) T cells. However, it is unclear whether CFA/I fimbriae alone are protective and whether other regulatory cytokines are involved, especially in the context for the EBI3-sharing cytokines, Treg-derived IL-35 and APC-derived IL-27, both capable of suppressing Th17 cells and regulating autoimmune diseases. Subsequent evaluation revealed that a single oral dose of purified, soluble CFA/I fimbriae protected against CIA as effectively as did Salmonella-CFA/I and found that Foxp3(+)CD39(+)CD4(+) T cells were the source of secreted IL-35, whereas IL-27 production by CD11c(+) cells was inhibited. Inquiring into their relevance, CFA/I fimbriae-treated IL-27R-deficient (WSX-1(-/-)) mice were equally protected against CIA as were wild-type mice, suggesting a limited role for IL-27. In contrast, CFA/I fimbriae-mediated protection was abated in EBI3(-/-) mice, accompanied by the loss of TGF-β- and IL-10-producing Tregs. Adoptive transfer of C57BL/6 CD39(+)CD4(+) T cells to EBI3(-/-) mice with concurrent CFA/I plus IL-35 treatment effectively stimulated Tregs suppressing proinflammatory collagen II-specific Th cells. In contrast, recipients cotransferred with C57BL/6 and EBI3(-/-) CD39(+)CD4(+) T cells and treated with CFA/I plus IL-35 were not protected, implicating the importance of endogenous IL-35 for conferring CFA/I-mediated protection. Thus, CFA/I fimbriae stimulate IL-35 required for the coinduction of TGF-β and IL-10.

    Psoriasis is a common human skin disease whereby abnormal production of inflammatory mediators is believed to play an important role in its pathogenesis. The IL12B gene, which encodes the shared IL-12p40 subunit in two cytokines, IL-12 and IL-23, and the IL23R gene, which encodes a subunit of the receptor for IL-23, were identified as psoriasis-susceptibility genetic factors in recent candidate gene and genome-wide association studies of Chinese and Europeans. Since there are significant differences in the incidence of psoriasis between Europeans and Japanese suggesting a genetic ethnic effect, we examined the association of IL12B and IL23R gene polymorphisms with psoriasis in a cohort of Japanese. In this study, we genotyped two SNPs (rs3212227 and rs6887695) in the IL12B gene and one SNP (rs11209026) in the IL23R gene using 560 Japanese psoriasis cases and 560 controls and compared our results with those previously published for Europeans and Asians. Our study showed significant associations between psoriasis and both IL12B gene SNPs, rs3212227 (odds ratio (OR) = 1.35, P = 4.94E-04) and rs6887695 (OR = 1.32, P = 2.00E-03), but no significant association between psoriasis and the IL23R SNP, rs11209026. Furthermore, a significant haplotype association was found for the IL12B gene protective haplotype C-C (OR = 0.71, P = 1.84E-04) in Japanese, as previously elucidated in the studies of European ancestry.

    Full Text Available Abstract Background The pleiotropic pro-inflammatory cytokine Interleukin (IL-18 has been proposed to play a role in schizophrenia, since elevated circulating levels of its protein and altered frequencies of genetic variants in its molecular system are reported in schizophrenic patients. Methods We analyzed 77 patients with schizophrenia diagnosis (SCZ and 77 healthy control subjects (HC for serum concentration of both IL-18 and its natural inhibitor, the IL-18 binding protein (IL-18BP. Results We confirmed that serum levels of total IL-18 are significantly increased in SCZ, as compared to HC. However, due to a highly significant increase in levels of circulating IL-18BP in SCZ, as compared to HC, the levels of free, bioactive IL-18 are not significantly different between the two groups. In addition, the relationships between the levels of IL-18 and its inhibitor, as well as between the two molecules and age appear dissimilar for SCZ and HC. In particular, the elevated levels of IL-18BP, likely a consequence of the body’s attempt to counteract the early prominent inflammation which characterizes schizophrenia, are maintained in earlier and later stages of the disease. However, the IL-18BP elevation appears ineffective to balance the IL-18 system in younger SCZ patients, while in older patients the levels of circulating bioactive IL-18 are comparable to those of HC, if not lower. Conclusions In conclusion, these findings indicate that the IL-18 system is perturbed in schizophrenia, supporting the idea that this pro-inflammatory cytokine might be part of a pathway of genetic and environmental components for vulnerability to the disease.
