Summer Research
Th17 cells are found to be heavily depleted in the gut of HIV patients. Even after successful antiretroviral therapy, HIV patients exhibit a smaller Th17 population for years after treatment. Previous research has found human intestinal endothelial cells (IEC) to increase HIV infection of helper T cells. Using CCR6 as a marker for Th17, we investigated the effect of IEC on HIV infection of Th17 cells. IECs were found to increase the preferential infection of resting and activated CCR6+ cells. Th17 cells are known to be more susceptible to HIV infection than other types of CD4+ T cells. IEC stimulation …

A major barrier to eradicating HIV is latent reservoirs in resting CD4+ T cells. Antiretroviral therapy is effective in bringing the viral load down to undetectable levels but is unable to eradicate the latent reservoir. Previous data from our lab revealed that when stimulated by intestinal endothelial cells (IEC), resting CD4+ T cells can be directly infected while remaining in a resting state, allowing formation of latent reservoirs. An additional study found that integrins, which are cell surface molecules, play a role in the interactions between endothelial cells (EC) and T cells. Our research further examines the role of integrins …
