抗逆转录病毒疗法(ART)已经控制了艾滋病毒/艾滋病的流行,但仍然需要一种根除病毒的治疗策略。ART的停止导致潜伏感染的CD 4 + T细胞的快速病毒反弹,表明单独控制病毒复制不能完全恢复免疫功能,也不能根除病毒储库。随着对促进病毒潜伏的因素和机制的更好理解,目前的方法主要集中在潜伏感染细胞的永久沉默(“阻断和锁定”)或重新激活潜伏感染细胞中的HIV-1基因表达,结合免疫恢复策略以从宿主中消除HIV感染细胞(“休克和杀死”)。在这篇综述中,我们提供了一个总结,目前最有前途的方法HIV-1治愈策略,包括潜伏期促进剂(LPA)和潜伏期逆转剂(LRA),已显示出承诺在体外,离体,并在人体临床试验,以减少HIV-1水库的分析。
Antiretroviral therapy (ART) has brought the HIV/AIDS epidemic under control, but a curative strategy for viral eradication is still needed. The cessation of ART results in rapid viral rebound from latently infected CD4+ T cells, showing that control of viral replication alone does not fully restore immune function, nor does it eradicate viral reservoirs. With a better understanding of factors and mechanisms that promote viral latency, current approaches are primarily focused on the permanent silencing of latently infected cells (“block and lock”) or reactivating HIV-1 gene expression in latently infected cells, in combination with immune restoration strategies to eliminate HIV infected cells from the host (“shock and kill”). In this review, we provide a summary of the current, most promising approaches for HIV-1 cure strategies, including an analysis of both latency-promoting agents (LPA) and latency-reversing agents (LRA) that have shown promise in vitro, ex vivo, and in human clinical trials to reduce the HIV-1 reservoir.
