Targeting HIV latency: Resting memory T cells, hematopoietic progenitor cells and future directions

摘要

Current therapy for HIV effectively suppresses viral replication and prolongs life, but the infection persists due, at least in part, to latent infection of long-lived cells. One favored strategy toward a cure targets latent virus in resting memory CD4+T cells by stimulating viral production. However, the existence of an additional reservoir in bone marrow hematopoietic progenitor cells has been detected in some treated HIV-infected people. This review describes approaches investigators have used to reactivate latent proviral genomes in resting CD4+T cells and hematopoietic progenitor cells. In addition, the authors review approaches for clearance of these reservoirs along with other important topics related to HIV eradication.
