IL-13 induces expression of CD36 in human monocytes through PPARgamma activation.

The class B scavenger receptor CD36 is a component of the pattern recognition receptors on monocytes that recognizes a variety of molecules. CD36 expression in monocytes depends on exposure to soluble mediators. We demonstrate here that CD36 expression is induced in human monocytes following exposure to IL-13, a Th2 cytokine, via the peroxisome proliferator-activated receptor (PPAR)gamma pathway. Induction of CD36 protein was paralleled by an increase in CD36 mRNA. The PPARgamma pathway was demonstrated using transfection of a PPARgamma expression plasmid into the murine macrophage cell line RAW264.7, expressing very low levels of PPARgamma, and in peritoneal macrophages from PPARgamma-conditional null mice. We also show that CD36 induction by IL-13 via PPARgamma is dependent on phospholipase A2 activation and that IL-13 induces the production of endogenous 15-deoxy-Delta12,14-prostaglandin J2, an endogenous PPARgamma ligand, and its nuclear localization in human monocytes. Finally, we demonstrate that CD36 and PPARgamma are involved in IL-13-mediated phagocytosis of Plasmodium falciparum-parasitized erythrocytes. These results reveal a novel role for PPARgamma in the alternative activation of monocytes by IL-13, suggesting that endogenous PPARgamma ligands, produced by phospholipase A2 activation, could contribute to the biochemical and cellular functions of CD36.

Jornades del moviment per la pau. Barcelona, 13 i 14 de novembre de 2009

Aquesta relatoria correspon a les Jornades del Moviment per la Pau coorganitzades per la Federació Catalana d’ONG per la Pau i l’Institut Català Internacional per la Pau, i que es van desenvolupar a Barcelona durant els dies 13 i 14 de novembre de 2009. L'objectiu era reflexionar i debatre sobre els plantejaments dels quals parteix el moviment, la identificació de noves realitats, els reptes de futur, i la possible adequació a nous enfocaments o estratègies per incrementar la incidència transformadora en el camp social i polític.

Estudio comparativo de los efectos hemodinámicos y anestésicos de la insuflación colonoscópica de aire versus dióxido de carbono (CO2) bajo sedación endovenosa con propofol

Estudi randomitzat on es van realitzar colonoscòpies amb insuflació amb aire o CO2 a 80 pacients sota sedació profunda amb propofol. Es van estudiar les dosis de propofol, el temps de despertar i el dolor desprès del procediment i es va comparar la incidència de nàusees, vòmits i complicacions hemodinàmiques en ambdós grups. Segons els nostres resultats, la insuflació amb CO2 no disminueix de forma significativa les necessitats de propofol ni el dolor postprocediment. El temps de despertar es redueix però no de forma significativa. La incidència de nàusees o vòmits i complicacions hemodinàmiques no varia entre grups.

Fascitis eosinofílica. A propósito de 13 casos.

Es tracta de la descripció d'una sèrie de 13 pacients amb fascitis eosinofílica diagnosticats en un hospital universitari entre 1989 i 2009. És una síndrome esclerodermiforme que es caracteritza per induració cutània i engruiximent i inflamació de la fàscia profunda. Es descriuen les característiques clíniques, el tractament rebut i l'evolució de 9 homes i 4 dones, amb una edat mitjana de 50 anys. Es va realitzar biòpsia profunda en tots els casos i els canvis van ser compatibles amb fascitis eosinofílica. Les característiques descrites en aquesta sèrie no difereixen de les descrites per altres autors.

Studies on the production and regulation of interleukin, IL-13, IL-4 and interferon-gamma in human Schistosomiasis mansoni

The production and regulation of interleukin (IL) IL-13, IL-4 and interferon-gamma was evaluated in different clinical forms of human schistosomiasis. The mechanisms of immune regulation are apparently different in the various clinical stages of the disease, some of them being antigen specific.

Action Plan For Health Research 2009 - 13

The purpose of this overviews to set the scene so as to assist with a fuller understanding of the Action Plan. It begins by outlining the purpose and objectives of the Action Plan. This is followed by the identificaton of the changes that the Action Plan will bring about over its time frame. The overview concludes by elaborating the structure and philosophy of the Action Plan.

Implementation of the Action Plan for Health Research 2009-13 - First year report 2009-2010

In November 2009 the Government published an Action Plan for Health Research. The Plan was prepared by the Health Research Group following a commitment set out in Building Ireland’s Smart Economy (December 2008). The Action Plan, which was approved by the Cabinet Committee on Science, Technology and Innovation, provides the lead on national priorities and resource allocation in health research. The Action Plan was prepared to prioritise a programme of actions essential to creating a health research system which supports outstanding individuals, working in world class facilities and conducting leading edge research focused on the needs of patients and the public. The HRG is committed to measuring the success of the Action Plan by the extent to which it meets these deliverables by 2013. One year on, this report reviews the progress being made to implement the Plan.
