Effect of histone deacetylase inhibitors on HIV production in latently infected, resting CD4(+) T cells from infected individuals receiving effective antiretroviral therapy.

Abstract

Persistence of the latent viral reservoir has been recognized as a major obstacle to eradicating human immunodeficiency virus (HIV) in infected individuals receiving antiretroviral therapy. It has been suggested that histone deacetylase inhibitors (HDACis) may purge HIV in the latent viral reservoir. However, the effect of HDACis on the degree and extent of HIV expression in the latent viral reservoir has not been fully delineated. Here we demonstrate that HDACis do not induce HIV production in the latent viral reservoir of aviremic individuals. Therefore, alternative therapeutic strategies may be necessary to eliminate HIV in the latent viral reservoir.
