有效的抗逆转录病毒疗法(ART)可抑制病毒血症,使感染人类免疫缺陷病毒1型(HIV - 1)的个体能够控制感染,并过上长寿且有质量的生活。然而,由于病毒储存库持续存在,其中的前病毒整合在宿主细胞DNA内,HIV - 1感染仍然无法治愈。这种潜伏感染不受抗逆转录病毒疗法的影响,并且对免疫系统隐匿。近期研究侧重于开发打破潜伏期的疗法。这些努力揭示了残留的病毒基因组,并强调需要清除潜伏感染细胞,也许可以通过改善HIV - 1特异性免疫反应的新旧策略来实现。在本综述中,我们探讨了根除已确立的HIV - 1感染并避免终身抗逆转录病毒疗法负担的新方法。
Effective antiretroviral therapy (ART) blunts viraemia, which enables HIV-1-infected individuals to control infection and live long, productive lives. However, HIV-1 infection remains incurable owing to the persistence of a viral reservoir that harbours integrated provirus within host cellular DNA. This latent infection is unaffected by ART and hidden from the immune system. Recent studies have focused on the development of therapies to disrupt latency. These efforts unmasked residual viral genomes and highlighted the need to enable the clearance of latently infected cells, perhaps via old and new strategies that improve the HIV-1-specific immune response. In this Review, we explore new approaches to eradicate established HIV-1 infection and avoid the burden of lifelong ART.
