HIV-1具有高突变率,并在宿主内以突变群的形式存在。HIV-1的快速进化使病毒超过宿主免疫系统,导致病毒持续存在。需要针对不可变成分的方法来清除HIV-1感染。在这里,我们报告说,CARD 8炎性小体的感觉HIV-1蛋白酶活性。HIV-1可以逃避CARD 8传感,因为它的蛋白酶在病毒出芽前在感染细胞中保持无活性。病毒蛋白酶的过早细胞内活化触发了CARD 8炎性小体介导的HIV-1感染细胞的焦亡。这种策略导致病毒再活化后患者CD 4 + T细胞中潜伏的HIV-1被清除。因此,我们的研究将CARD 8鉴定为HIV-1的炎性感受器,这有望成为清除持续HIV-1感染的策略。
HIV-1 has high mutation rates and exists as mutant swarms within the host. Rapid evolution of HIV-1 allows the virus to outpace the host immune system, leading to viral persistence. Approaches to target immutable components are needed to clear HIV-1 infection. Here, we report that the CARD8 inflammasome senses HIV-1 protease activity. HIV-1 can evade CARD8 sensing because its protease remains inactive in infected cells prior to viral budding. Premature intracellular activation of the viral protease triggered CARD8 inflammasome-mediated pyroptosis of HIV-1-infected cells. This strategy led to the clearance of latent HIV-1 in patient CD4+ T cells after viral reactivation. Thus, our study identifies CARD8 as an inflammasome sensor of HIV-1, which holds promise as a strategy for clearance of persistent HIV-1 infection.
