This observational or N/A phase trial investigates HIV and Immunodeficiencies and is currently actively recruiting participants. Medstar Health Research Institute leads this study, which shows 73 recorded versions since 1993 — indicating substantial longitudinal coverage. Longitudinal tracking of infectious disease trials helps identify durability of treatment effects.

Study Description(click to expand)

We are studying virologic and/or immunologic parameters of HIV infection and other infectious or non-infectious immune deficiency diseases in order to better understand the pathogenesis of HIV. Because of the lack of an adequate animal model it is generally necessary to utilize human peripheral blood cells for studying aspects of either in vivo or in vitro HIV infection. We wish to be able to continue to elucidate many pathogenic aspects of HIV infection in relation to other infectious or non-infectious immune regulation and dysregulation using human peripheral blood mononuclear cells as a model.
