Abstract

Persistence of HIV-1 in latently infected CD4(+) T-cells prevents eradication in HIV-infected treated patients. Latency is characterized by a reversible silencing of transcription of integrated HIV-1. Several molecular mechanisms have been described which contribute to latency, including the establishment and maintenance of repressive chromatin on the HIV-1 promoter. Histone deacetylation is a landmark modification associated with transcriptional repression of the HIV-1 promoter and inhibition of histone deacetylase enzymes (HDACs) reactivates latent HIV-1. Here, we review the different HDAC inhibitors that have been studied in HIV-1 latency and their therapeutic potential in reactivating latent HIV-1.

摘要

潜伏感染的CD4(+) T细胞中HIV-1的持续存在阻碍了HIV感染患者的病毒清除。潜伏期的特征是整合的HIV-1转录可逆性沉默。已经描述了几种导致潜伏期的分子机制,包括在HIV-1启动子上建立和维持抑制性染色质。组蛋白去乙酰化是与HIV-1启动子转录抑制相关的标志性修饰,抑制组蛋白脱乙酰酶(HDAC)可重新激活潜伏的HIV-1。在此,我们综述了在HIV-1潜伏期研究的不同HDAC抑制剂及其在重新激活潜伏HIV-1方面的治疗潜力。
