登革病毒(DENV)与其他病毒一样,与宿主细胞机制密切相互作用以完成其生命周期。在感染过程中,DENV与几种具有前病毒活性的宿主因子相互作用以支持其感染。同时,它还必须通过抗病毒活性来逃避或对抗宿主因子,从而抑制其感染。这些分子病毒-宿主相互作用在决定DENV感染的成功方面起着至关重要的作用。因此,破译这种相互作用对于理解病毒在其自然宿主中的适应性至关重要。虽然已经广泛研究了DENV-哺乳动物宿主相互作用,但是尽管DENV-蚊子宿主相互作用在控制DENV传播中具有重要性,但是还没有做太多的工作来表征DENV-蚊子宿主相互作用。在这里,为了提供我们目前对DENV-蚊子相互作用的理解的快照,我们回顾了在其蚊子载体埃及伊蚊和白纹伊蚊中鉴定与DENV感染相关的宿主因子和细胞过程的文献,特别关注DENV-蚊子组学研究。这些知识为DENV生命周期提供了基本见解,并可能有助于新型抗病毒策略的开发。
Dengue virus (DENV), like other viruses, closely interacts with the host cell machinery to complete its life cycle. Over the course of infection, DENV interacts with several host factors with pro-viral activities to support its infection. Meanwhile, it has to evade or counteract host factors with anti-viral activities which inhibit its infection. These molecular virus-host interactions play a crucial role in determining the success of DENV infection. Deciphering such interactions is thus paramount to understanding viral fitness in its natural hosts. While DENV-mammalian host interactions have been extensively studied, not much has been done to characterize DENV-mosquito host interactions despite its importance in controlling DENV transmission. Here, to provide a snapshot of our current understanding of DENV-mosquito interactions, we review the literature that identified host factors and cellular processes related to DENV infection in its mosquito vectors, Aedes aegypti and Aedes albopictus, with a particular focus on DENV-mosquito omics studies. This knowledge provides fundamental insights into the DENV life cycle, and could contribute to the development of novel antiviral strategies.
