A recent study describes a new Dual CAR T cell immunotherapy that can help fight HIV infection.
A recent study published in the journal Nature Medicine, led by researchers James Riley, PhD, a professor of Microbiology at the Perelman School of Medicine at the University of Pennsylvania, and Todd Allen, PhD, a professor of Medicine at Harvard Medical School and Group Leader at the Ragon Institute of MGH, MIT and Harvard, describes a new Dual CAR T cell immunotherapy that can help fight HIV infection. The paper's first authors are Colby Maldini, a graduate student at the University of Pennsylvania and Daniel Claiborne, PhD, a research fellow at the Ragon Institute.

"This study highlights how relatively straightforward alterations to the way T cells are engineered can lead to dramatic changes in their potency and durability," Riley said. "This finding has significant implications for using engineered T cells to fight both HIV and cancer."

The global HIV epidemic impacts more than 35 million people around the world. Antiretroviral therapy (ART) is a daily treatment that can control, but not cure, HIV infection. However, access and lifelong adherence to a daily regimen is a significant barrier for many people living with HIV. A major hurdle to HIV cure is the viral reservoir, copies of HIV hidden away in the genome of infected cells. If ART treatment is stopped, the virus is able to rapidly make…
