Maintenance of HIV latency in vitro has been linked to methylation of HIV DNA. However, examinations of the degree of methylation of HIV DNA in the latently infected, resting CD4(+) T cells of infected individuals receiving antiretroviral therapy have been limited. Here, we show that methylation of the HIV 5' long terminal repeat (LTR) in the latent viral reservoir of HIV-infected aviremic individuals receiving therapy is rare, suggesting that other mechanisms are likely involved in the persistence of viral latency.
体外维持 HIV 潜伏期与 HIV DNA 的甲基化有关。然而，对接受抗逆转录病毒治疗的感染者潜伏感染、静止的 CD4(+)T 细胞中 HIV DNA 甲基化程度的检测受到限制。在这里，我们表明，接受治疗的 HIV 血症抑制个体潜伏病毒库中 HIV 5'长末端重复（LTR）的甲基化很少，这表明其他机制可能参与了病毒潜伏期的持续存在。
