细胞的膜景观在被病毒感染后通常会发生急剧变化。在研究充分的正链RNA病毒脊髓灰质炎病毒的情况下,短的感染周期在感染早期诱导囊泡和管状结构,在感染后期诱导双膜囊泡。在这篇综述中,目前的理解膜的变化,在PV感染的细胞,宿主和病毒的因素,促进这些变化,以及这些变化可能会促进病毒复制将进行讨论。在感染期间参与膜重排的宿主因子包括COPI和COPII分泌途径、脂质激酶和自噬途径的组分。细胞膜的作用包括作为RNA复制复合物的支架和成熟病毒的退出。最后,最近的研究表明,并不是所有的小核糖核酸病毒是真正的“无包膜”的领域的背景下进行了讨论,提高了细胞衍生的膜在提供脊髓灰质炎病毒颗粒的细胞外空间中发挥作用的可能性。
The membrane landscape of a cell often changes drastically upon infection by a virus. In the case of the well-studied positive strand RNA virus poliovirus, the short infection cycle induces vesicles and tubular structures early in infection, and double-membraned vesicles late in infection. In this review, the current understanding of membrane changes in a PV-infected cell, the host and viral factors that facilitate these changes, and how these changes may promote virus replication will be discussed. Host factors involved in membrane rearrangement during infection include components of the COPI and COPII secretory pathways, lipid kinases, and the autophagy pathway. The roles of cellular membranes include acting as a scaffold for the RNA replication complex and roles in exit of mature virus. Finally, recent studies suggesting that not all picornaviruses are truly “non-enveloped” are discussed in the context of the field, raising the possibility that cell-derived membranes play a role in delivering poliovirus particles to the extracellular space.
