本综述提出了 HIV-1 潜伏期和根除领域关键术语的定义。在根除的背景下,储存库是一种允许具有复制能力的HIV-1在接受最佳抗逆转录病毒治疗的患者体内持续存在数年的细胞类型。水库对于可能进行治愈尝试的患者群体来说是根除的障碍。停止病毒复制对于根除病毒至关重要,并提出了评估这一目标是否已实现的定义和标准。讨论了可能作为 HIV-1 储存库的细胞类型。目前,只有潜伏感染的静息 CD4+ T 细胞符合拟议的储存库定义,并且需要更多证据来证明包括造血干细胞和巨噬细胞在内的其他细胞类型符合这一定义。迫切需要对肠道相关淋巴组织和中枢神经系统中的潜在储存库进行进一步研究。
This review proposes definitions for key terms in the field of HIV-1 latency and eradication. In the context of eradication, a reservoir is a cell type that allows persistence of replication-competent HIV-1 on a time scale of years in patients on optimal antiretroviral therapy. Reservoirs act as a barrier to eradication in the patient population in whom cure attempts will likely be made. Halting viral replication is essential to eradication, and definitions and criteria for assessing whether this goal has been achieved are proposed. The cell types that may serve as reservoirs for HIV-1 are discussed. Currently, only latently infected resting CD4+ T cells fit the proposed definition of a reservoir, and more evidence is necessary to demonstrate that other cell types including hematopoietic stem cells and macrophages fit this definition. Further research is urgently required on potential reservoirs in the gut-associated lymphoid tissue and the central nervous system.
