Is a Pacific Coexistence Between Virus and Host the Unexploited Path That May Lead to an HIV Functional Cure?

The SupT1 cell line supports optimal HIV-1 replication, and prolonged in vitro replication in SupT1 cells renders the virus significantly less virulent. This raises the question of whether the infusion of SupT1 cells could be used as a cell-based therapy to induce a pacific coexistence between the HIV virus and its human host. In a recent study, I investigated this potential therapeutic strategy in vitro. The results suggested that this approach should be further explored in HIV-susceptible animal models. Such studies may lead to the development of a functional cure for HIV infection.
