Effect of HIV infection on co-stimulatory capacity of dendritic cells
Ontology highlight
ABSTRACT: HIV uses dendritic cells as a carrier to infect its target CD4+ T cells. At the same time, it also hampers DCs function in terms of their T cell stimulatory capacity and cytokine secretion. We have shown that HIV causes reduction in the expression of co-stimulatory molecules, CD80 and CD86 by DCs at the mRNA level irrespective of the viral subtype or the mode in DC-HIV interaction. The microarray experiments were performed to understand the changes in the transcription factor profile of HIV infected DCs which may in turn lead to reduced CD80/CD86 expression as well as the effect of HIV infection on other co-stimulatory molecules on DCs. The data suggests that TFs NFKB1, NFKB2, REL and MYB may be responsible for the observed decrease in CD80 and CD86 expression and that HIV infection also hampers the expression of other co-stimulatory molecules like CD70, CD30, 4-1BB, OX40L etc.
