虫媒病毒性疾病的全球流行率不断上升,这突出表明有必要提高我们对其生物学的理解。由于缺乏研究病毒-蚊子相互作用的分子工具,这一领域的研究受到了阻碍。本研究构建了一株稳定表达寨卡病毒(ZIKV)衣壳蛋白的埃及伊蚊细胞系,目的是通过定量无标记蛋白质组学研究病毒-载体蛋白-蛋白相互作用。我们鉴定了157个相互作用体,并表明其中8个在蚊子细胞感染寨卡病毒期间具有潜在的前病毒活性。值得注意的是,过渡内质网蛋白TER94的沉默可以阻止ZIKV衣壳降解并显著减少病毒复制。如果在人细胞中使用抑制剂阻断TER94同源物(VCP)功能,则观察到类似的结果。此外,我们发现E3泛素蛋白连接酶UBR5介导了TER94与ZIKV衣壳之间的相互作用。我们的研究表明,在寨卡病毒感染期间,TER94/VCP具有在人和蚊子细胞之间保守的前病毒功能。作者利用表达寨卡病毒(ZIKV)衣壳的蚊子细胞系,进行了蛋白质组学实验,检索了157种蛋白相互作用因子,其中8种可作为前病毒因子,表明过渡性内质网94 (TER94)及其人类同源物VCP靶向寨卡病毒衣壳,使其蛋白酶体降解以促进感染。
The escalating global prevalence of arboviral diseases emphasizes the need to improve our understanding of their biology. Research in this area has been hindered by the lack of molecular tools for studying virus-mosquito interactions. Here, we develop an Aedes aegypti cell line which stably expresses Zika virus (ZIKV) capsid proteins in order to study virus-vector protein-protein interactions through quantitative label-free proteomics. We identify 157 interactors and show that eight have potentially pro-viral activity during ZIKV infection in mosquito cells. Notably, silencing of transitional endoplasmic reticulum protein TER94 prevents ZIKV capsid degradation and significantly reduces viral replication. Similar results are observed if the TER94 ortholog (VCP) functioning is blocked with inhibitors in human cells. In addition, we show that an E3 ubiquitin-protein ligase, UBR5, mediates the interaction between TER94 and ZIKV capsid. Our study demonstrates a pro-viral function for TER94/VCP during ZIKV infection that is conserved between human and mosquito cells. Here the authors develop mosquito cell lines expressing Zika virus (ZIKV) capsid and perform proteomics experiments retrieving 157 protein interactors, of which they show 8 to act as pro-viral factors, showing the transitional endoplasmic reticulum 94 (TER94) and its human ortholog VCP target ZIKV capsid to proteasomal degradation to facilitate infection.
