How B cells may help HIV hide in the body

Elucidating the role of B cell mediated trans infection in the establishment of the latent HIV-1 reservoir

['FUNDING_R01'] · UNIVERSITY OF PITTSBURGH AT PITTSBURGH · NIH-11137670

This project looks at whether B cells can pass HIV directly to T cells and help create the hidden, long-lived HIV reservoir in people.

What this research studies

If you join, researchers may ask for blood or other samples so they can study your immune cells. They will compare B cells from people who naturally control HIV without treatment to those from people who do not, and use lab tests to see how B cells transfer virus to resting CD4+ T cells. The team will also use humanized mouse models and molecular measurements of HIV DNA to track how hidden reservoirs form. Results will combine human samples and lab models to clarify whether B cell–mediated trans-infection helps establish long-lived HIV infection pockets.

Who could benefit from this research

Good fit: Ideal participants would be adults living with HIV who can provide blood or other samples, including people who naturally control the virus without antiretroviral therapy.

Not a fit: People without HIV or those unable to give samples are unlikely to benefit directly from participating.

Why it matters

Potential benefit: If successful, this work could point to new ways to prevent or reduce the hidden HIV reservoir, which is a major barrier to cure.

How similar studies have performed: Previous laboratory studies have shown B cells can transfer HIV to T cells, but direct evidence in living humans linking this to the long-lived reservoir remains limited.
