人类免疫缺陷病毒1 (HIV-1)的核进入机制,需要生产性感染,尚不完全清楚。在此,我们报道了在分别感染VSV-G和天然Env蛋白的HIV-1假型感染的HeLa细胞和活化的CD4+ T细胞中,含有内吞的HIV-1的Rab7+晚期核内体通过一种分子机制促进核膜内陷(NEIs)的形成,该分子机制涉及由外核膜蛋白VAP-A、过度磷酸化的ORP3和Rab7组成的VOR复合体。沉默VAP-A或ORP3以及药物介导的Rab7与ORP3-VAP-A结合的损伤可抑制HIV-1组分的核转移和产生性感染。在hiv -1抵抗的静止CD4+ T细胞中,ORP3没有过度磷酸化,也没有形成VOR复合物和nei。这种新的细胞途径及其分子参与者是潜在的治疗靶点,可能与其他需要进入核来完成其生命周期的病毒共享。像HIV-1这样的病毒必须将其内容物传递到宿主t细胞核中进行复制。在这里,Santos等人表明,内吞的HIV-1促进由VAP-A、ORP3和Rab7宿主蛋白复合物介导的核膜内压,使HIV-1能够进入t细胞核。
The mechanism of human immunodeficiency virus 1 (HIV-1) nuclear entry, required for productive infection, is not fully understood. Here, we report that in HeLa cells and activated CD4+ T cells infected with HIV-1 pseudotyped with VSV-G and native Env protein, respectively, Rab7+ late endosomes containing endocytosed HIV-1 promote the formation of nuclear envelope invaginations (NEIs) by a molecular mechanism involving the VOR complex, composed of the outer nuclear membrane protein VAP-A, hyperphosphorylated ORP3 and Rab7. Silencing VAP-A or ORP3 and drug-mediated impairment of Rab7 binding to ORP3-VAP-A inhibited the nuclear transfer of the HIV-1 components and productive infection. In HIV-1-resistant quiescent CD4+ T cells, ORP3 was not hyperphosphorylated and neither VOR complex nor NEIs were formed. This new cellular pathway and its molecular players are potential therapeutic targets, perhaps shared by other viruses that require nuclear entry to complete their life cycle. Viruses such as HIV-1 must deliver their content into host T-cell nuclei to replicate. Here, Santos et al. show that endocytosed HIV-1 promotes nuclear envelope invagination mediated by VAP-A, ORP3, and Rab7 host protein complex that allow HIV-1 to access T-cell nuclei.
