Combination antiretroviral therapy (ART) can suppress plasma HIV to undetectable levels, allowing HIV-infected individuals who are treated early a nearly normal life span. Despite the clear ability of ART to prevent morbidity and mortality, it is not curative. Even in individuals who have full suppression of viral replication on ART, there are resting memory CD4+ T cells that harbor stably integrated HIV genomes, which are capable of producing infectious virus upon T cell activation. This latent viral reservoir is considered the primary obstacle to the development of an HIV cure, and recent efforts in multiple areas of HIV research have been brought to bear on the development of strategies to eradicate or develop a functional cure for HIV. Reviews in this series detail progress in our understanding of the molecular and cellular mechanisms of viral latency, efforts to accurately assess the size and composition of the latent reservoir, the characterization and development of HIV-targeted broadly neutralizing antibodies and cytolytic T lymphocytes, and animal models for the study HIV latency and therapeutic strategies.
联合抗逆转录病毒疗法(ART)可将血浆中的HIV抑制到检测不到的水平,使早期接受治疗的HIV感染者拥有接近正常的寿命。尽管ART有明确的预防发病和死亡的能力,但它并不能治愈疾病。即使是在接受ART治疗后病毒复制得到完全抑制的个体中,仍存在携带稳定整合的HIV基因组的静息记忆CD4+T细胞,这些细胞在T细胞激活时能够产生传染性病毒。这种潜伏性病毒库被认为是实现HIV治愈的主要障碍,近期HIV研究多个领域的努力都致力于开发根除HIV或实现功能性治愈的策略。本系列综述详细介绍了我们在理解病毒潜伏的分子和细胞机制方面取得的进展、准确评估潜伏病毒库大小和组成的努力、针对HIV的广谱中和抗体和细胞毒性T淋巴细胞的表征与开发,以及用于研究HIV潜伏和治疗策略的动物模型。
