为了感染细胞,多瘤病毒 (PyV) 从细胞表面运输到内质网 (ER),在那里它劫持 ER 相关降解 (ERAD) 机制的元件,穿透 ER 膜并到达细胞质。病毒从细胞质转运到细胞核,实现病毒基因组的转录和复制,从而导致裂解感染或细胞转化。 PyV 如何利用 ERAD 机制穿过 ER 膜并进入胞质溶胶(感染的决定性步骤)仍然是个谜。然而,最近的研究慢慢地揭示了这个过程的许多方面。这些新的见解应该会推动我们开发更有效的疗法来治疗 PyV 引起的人类疾病。
To infect cells, polyomavirus (PyV) traffics from the cell surface to the endoplasmic reticulum (ER) where it hijacks elements of the ER-associated degradation (ERAD) machinery to penetrate the ER membrane and reach the cytosol. From the cytosol, the virus transports to the nucleus, enabling transcription and replication of the viral genome that leads to lytic infection or cellular transformation. How PyV exploits the ERAD machinery to cross the ER membrane and access the cytosol, a decisive infection step, remains enigmatic. However, recent studies have slowly unraveled many aspects of this process. These emerging insights should advance our efforts to develop more effective therapies against PyV-induced human diseases.
