登革病毒与细胞自噬

Dengue virus and cell autophagy

登革病毒(dengue virus,DENV)在胞内复制、宿主间传播和机体内致病机制等方面均受到细胞自噬的影响,本文依据国内外最新研究进展以DENV与细胞自噬的关系为重点展开综述。自噬是一种真核生物普遍具备的、用于应对外界压力和维持细胞内稳态的程序性蛋白降解途径,其在保护细胞免受病毒等外源病原体侵染的机制中发挥重要作用。但是自噬在DENV的复制过程中发挥了相反的作用。自噬不仅为病毒复制提供了复制场所,而且为其提供能量来源,细胞自噬还参与了部分DENV致病过程。总之,自噬有助于DENV的复制。

Dengue viruses(DENV)are seriously affected by cell autophagy in intracellular replication,transmission between host,and the pathogenic mechanism.Here,the latest research progress of complex interplay between DENV and cell autophagy were reviewed in this paper.Autophagy,a cellular procedural protein degradation pathway generally possessed by all eukaryotes plays a key role in response to outside pressure and maintaining cellular homeostasis.This catabolic pathway also promotes cell survival against the invasion of pathogens such as various viruses.However,autophagy plays an opposite role in the replication of DENV.Autophagy not only provides a replication site for viruses to replicate,but also provides a source of energy for this process.Cell autophagy also participates in the pathogenesis of some DENV infection.In short,autophagy contributes to the replication of DENV.
