Dendritic cells are innate immune cells that are crucial in bridging the innate and adaptive immune responses.  Our research is focused on understanding how HIV-1 infection influences dendritic cell function and their interactions with T cells.  Recently, we have begun to investigate the contribution of intestinal dendritic cells to the gastrointestinal pathology observed in patients infected with HIV-1.
