Some persons living with HIV also have hematologic malignancies, which require treatment by hematopoetic stem cell transplant (HSCT). Eberhard et al. collected clinical, virologic, and immunologic data on 16 such individuals before and after transplant. They observed incomplete T cell reconstitution after HSCT, although there was de novo priming of HIV-specific T cells. A period of high immune activation indicated a window of vulnerability for HIV reservoir re-seeding. These valuable data may hold clues for helping other individuals in a similar situation, and more generally for curing HIV.
