在这里,我们回顾了病毒和细胞对泡沫病毒(FVs)进入和细胞内运输的要求,从而导致病毒序列整合到宿主细胞基因组中。病毒编码的糖蛋白包含所有必需的病毒决定因子,这些决定因子参与宿主膜的吸收并触发病毒颗粒的摄取。然而,直到最近,人们才了解到FV与宿主细胞受体相互作用的一些细节。最近的研究表明,细胞蛋白聚糖中的糖胺聚糖,特别是硫酸肝素,是最重要的。FVs以一种物种特异性的方式遇到目标细胞的内源性机制,这些机制在某些情况下被用于融合并进一步进入细胞质。主要由ph依赖性内吞作用触发,病毒和细胞膜融合并释放裸露的FV衣壳到细胞质中。然后,完整的FV衣壳沿着微管穿梭,并被发现在中心体附近积聚,在那里它们可以长时间保持潜伏状态。根据宿主细胞周期状态,FV衣壳最终会解体,并且通过尚未明确的机制,预整合复合体进入宿主细胞染色质。宿主细胞有丝分裂最终允许病毒基因组整合,最终开始新一轮的病毒复制。
Here we review viral and cellular requirements for entry and intracellular trafficking of foamy viruses (FVs) resulting in integration of viral sequences into the host cell genome. The virus encoded glycoprotein harbors all essential viral determinants, which are involved in absorption to the host membrane and triggering the uptake of virus particles. However, only recently light was shed on some details of FV’s interaction with its host cell receptor(s). Latest studies indicate glycosaminoglycans of cellular proteoglycans, particularly heparan sulfate, to be of utmost importance. In a species-specific manner FVs encounter endogenous machineries of the target cell, which are in some cases exploited for fusion and further egress into the cytosol. Mostly triggered by pH-dependent endocytosis, viral and cellular membranes fuse and release naked FV capsids into the cytoplasm. Intact FV capsids are then shuttled along microtubules and are found to accumulate nearby the centrosome where they can remain in a latent state for extended time periods. Depending on the host cell cycle status, FV capsids finally disassemble and, by still poorly characterized mechanisms, the preintegration complex gets access to the host cell chromatin. Host cell mitosis finally allows for viral genome integration, ultimately starting a new round of viral replication.
