使用抗逆转录病毒疗法(ART)治疗人类免疫缺陷病毒(HIV)在将血浆病毒血症控制到无法检测的水平方面非常成功。然而,艾滋病毒的完全治愈受到复制能力的艾滋病毒的存在的阻碍,这种病毒整合在宿主基因组中,可以在称为病毒潜伏期的静息状态下长期存在。静息记忆性CD4+ T细胞被认为是持续性HIV感染的最大储存库,并且经常被专门作为HIV治疗的主要目标进行研究。然而,其他细胞类型,如循环单核细胞和组织驻留的巨噬细胞,可以窝藏集成的,复制能力的HIV。为了开发治疗HIV的方法,不仅需要关注T细胞区室,还需要关注持续HIV感染的骨髓储库。在这篇综述中,我们总结了它们的重要性时,设计艾滋病毒治疗策略和挑战相关的识别和特定的目标,通过“休克和杀死”的方法。
The use of antiretroviral therapy (ART) for Human Immunodeficiency Virus (HIV) treatment has been highly successful in controlling plasma viremia to undetectable levels. However, a complete cure for HIV is hindered by the presence of replication-competent HIV, integrated in the host genome, that can persist long term in a resting state called viral latency. Resting memory CD4+ T cells are considered the biggest reservoir of persistent HIV infection and are often studied exclusively as the main target for an HIV cure. However, other cell types, such as circulating monocytes and tissue-resident macrophages, can harbor integrated, replication-competent HIV. To develop a cure for HIV, focus is needed not only on the T cell compartment, but also on these myeloid reservoirs of persistent HIV infection. In this review, we summarize their importance when designing HIV cure strategies and challenges associated to their identification and specific targeting by the “shock and kill” approach.
