HIV/Tuberculosis Immunology. Through the Dar Dar Trial, the largest trial of a TB vaccine candidate in the world to date, we have analyzed how spontaneous and vaccine-mediated immune responses protect HIV-infected adults from TB.
Mucosal transmission of HIV. We have investigated how semen protects target cells from HIV infection by modulating T cell receptor expression via modulation of cell surface expression of HIV receptor and co-receptors, thereby shaping the tropism of the transmitted virus. We have also found that semen has a profound anti-inflammatory effect on CD4+ T cells. Furthermore, in collaboration with the Wira lab at Dartmouth, we have studied how endogenous microbicides in cervicovaginal fluids protect women from HIV transmission to target cells.
Immunology of regulatory T cells during HIV infection. We have examined the role of regulatory T cell-associated costimulatory molecule interactions in modulating HIV-specific T cell responses and susceptibility to cell death, and the role of regulatory T cells in protecting CD4+ target cells from HIV infection.
