Abstract
Human immunodeficiency virus type 1 (HIV-1) is a retrovirus that integrates into the host cell’s DNA as a provirus. Transcription from the provirus is regulated in large part by cellular proteins and epigenetic factors. These may be repressive or permissive to productive infection. The host factors that regulate this balance are therefore attractive targets for HIV-1 therapeutics. Indeed, proviral chromatin is the focus of two of the current HIV-1 cure strategies. “Shock and Kill” uses latency reversal agents to open the provirus’s chromatin, promoting high levels of gene expression that induce the killing of infected cells. “Block and Lock” uses latency promoting agents to induce heterochromatin, blocking transcription and forcing HIV-1 into a state of deep latency. Here, the compounds investigated in both strategies are reviewed, including their chemical structures, mechanisms of action, and clinical results. Finally, the use of CRISPR-Cas therapeutics and the impact of chromatin architecture on its efficacy are discussed.
