Lipodystrophic syndrome is a major side effect of highly active antiviral therapy. Fat tissue redistribution is associated with changes in adipocyte gene expression and in circulating levels of adipocytokines involved in the development of insulin resistance. However, the evidence that HIV drugs accumulate into human adipocytes and have a...

Hepatitis C virus (HCV) becomes chronic in about 85 % of infected individuals, whereas only 15 % of infected people clear spontaneously the virus. The progression of hepatitis C to chronic status is associated to a profound down-regulation of CD4 and CD8 multispecific immune response.

To characterize the response of respiratory epithelium to infection by Staphylococcus aureus (S. aureus), human airway cells were incubated for 1 to 24 h with a supernatant of a S. aureus culture (bacterial supernatant), then profiled with a pangenomic DNA microarray. Because an upregulation of many genes was noticed around 3 h, three...
