高效抗逆转录病毒疗法(HAART)抑制艾滋病毒-1复制,改变感染患者的前景。然而,在HAART期间,具有复制能力的病毒的储存库仍然存在,当治疗停止时,艾滋病毒-1的高复制率又回来了。最近对艾滋病毒-1潜伏期的洞察,以及一份关于艾滋病毒-1感染在一个人身上被根除的报告,重新燃起了人们对寻找艾滋病毒-1感染的治疗方法的兴趣。根除HIV-1的策略包括基因治疗和造血干细胞移植,刺激宿主免疫以控制HIV-1复制,以及靶向静止记忆CD4+T细胞中的潜伏HIV-1。未来的努力应该旨在更好地了解如何用基因工程细胞重建CD4+T细胞隔间,对HIV-1复制实施免疫控制,以及识别和消除所有病毒库。
Highly active antiretroviral therapy (HAART) suppresses HIV-1 replication, transforming the outlook for infected patients. However, reservoirs of replication-competent forms of the virus persist during HAART, and when treatment is stopped, high rates of HIV-1 replication return. Recent insights into HIV-1 latency, as well as a report that HIV-1 infection was eradicated in one individual, have renewed interest in finding a cure for HIV-1 infection. Strategies for HIV-1 eradication include gene therapy and hematopoietic stem cell transplantation, stimulating host immunity to control HIV-1 replication, and targeting latent HIV-1 in resting memory CD4+ T cells. Future efforts should aim to provide better understanding of how to reconstitute the CD4+ T cell compartment with genetically engineered cells, exert immune control over HIV-1 replication, and identify and eliminate all viral reservoirs.
