MHC-derived allopeptide activates TCR-biased CD8+ Tregs and suppresses organ rejection.

In a rat heart allograft model, preventing T cell costimulation with CD40Ig leads to indefinite allograft survival, which is mediated by the induction of CD8+CD45RClo regulatory T cells (CD8+CD40Ig Tregs) interacting with plasmacytoid dendritic cells (pDCs). The role of TCR-MHC-peptide interaction in regulating Treg activity remains a topic of debate. Here, we identified a donor MHC class II-derived peptide (Du51) that is recognized by TCR-biased CD8+CD40Ig Tregs and activating CD8+CD40Ig Tregs in both its phenotype and suppression of antidonor alloreactive T cell responses.

[Seasonal and pandemic A (H1N1) 2009 influenza vaccination coverage among health-care workers in a French university hospital].

The aim of this study was to highlight the perceived risk, behavioural changes and acceptance of the seasonal and pandemic (H1N1) 2009 influenza vaccine by healthcare workers in a French teaching hospital. We surveyed healthcare workers from the Angers French teaching hospital (CHU) using a cross-sectional intercept design during phase 5A of the French National Plan for the Prevention and Control of the 2009 "Pandemic Influenza". Professionals were asked to take the survey in their workplace from November 2009 to February 2010.

Acceptance of seasonal and pandemic a (H1N1) 2009 influenza vaccination by healthcare workers in a french teaching hospital.

Introduction: The aim of this study was to highlight the perceived risks, behavioural changes and the rate of acceptance of seasonal and pandemic (H1N1) 2009 influenza vaccines by healthcare workers (HCWs) in a French Teaching Hospital.

Methods: We sampled HCWs from the Angers French Teaching Hospital (France) using a cross-sectional intercept design during phase 5A of the 2009 French National Plan for the Prevention and Control of 'Pandemic Influenza'. From November 2009 to February 2010, HCWs were approached in the workplace to undertake the survey.

[Chemical submission].

Introduction: The clinical submission syndrome is well known by the general population, but too frequently ignored by physicians.

Observation: A 23 year-old woman was drugged by a third person wishing to sexually abuse of her. The diagnosis was proved biologically after the judicial enquiry.
