慢病毒与逆转录病毒家族其他成员的区别在于它们能够穿过核孔复合体感染非分裂细胞。介导 HIV-1 核输入的病毒决定因子是病毒衣壳 (CA) 蛋白,它形成圆锥形核心,保护成熟病毒颗粒中的 HIV-1 基因组。最近,开发的一系列用于监测感染中融合后事件的新方法挑战了以前的病毒生命周期教科书模型,该模型将衣壳核心的逆转录和分解视为在细胞质中完成的事件。在这篇综述中,我们总结了这些最新发现,并描述了它们对我们理解 HIV-1 感染时空分期的影响,重点关注核输入及其对病毒生命周期其他方面的影响。
A hallmark feature of lentiviruses, which separates them from other members of the retrovirus family, is their ability to infect non-dividing cells by traversing the nuclear pore complex. The viral determinant that mediates HIV-1 nuclear import is the viral capsid (CA) protein, which forms the conical core protecting the HIV-1 genome in a mature virion. Recently, a series of novel approaches developed to monitor post-fusion events in infection have challenged previous textbook models of the viral life cycle, which envisage reverse transcription and disassembly of the capsid core as events that complete in the cytoplasm. In this review, we summarize these recent findings and describe their implications on our understanding of the spatiotemporal staging of HIV-1 infection with a focus on the nuclear import and its implications in other aspects of the viral lifecycle.
