Abstract Chimeric antigen receptor T (CAR-T) cell therapy, renowned for its successes in cancer treatment, is now entering the field of human immunodeficiency virus (HIV) therapy, presenting both opportunities and challenges. With the emergence of broadly neutralizing antibodies, multi-target CARs, and T cell receptor–like antibodies aimed at increasing specificity in targeting HIV reservoirs, CAR-T therapy is synergizing with other cutting-edge treatments, including gene-editing technologies, therapeutic vaccines, and latency-reversing agents, in pursuit of a potential functional cure. In this review, we delve into the role of CAR-T therapy in HIV treatment, highlighting its potential to overcome clinical obstacles. We discuss advancements in targeting strategies within CAR constructs and the intricate regulation of T cell proliferation and chemotaxis. Moreover, we explore the use of diverse immune cells, such as gamma-delta T cells and natural killer cells. We review advanced biotechnologies, manufacturing innovations, viral mechanisms, and immune microenvironments. We also discuss the current research landscape and potential future applications of CAR-T therapy against HIV, which remains a critical global health challenge.
