寨卡病毒(ZIKV)于2016年成为全球健康问题,因为它与先天性小头畸形和其他出生缺陷有关。黄病毒,包括ZIKV,重组内质网(ER)以形成病毒质,即组装病毒颗粒的隔室。微管(MT)和微管组织中心(MTOC)协调细胞中的结构和运输功能,MT还支持黄病毒的复制。在这里,我们研究了MT和细胞的MTOC对ZIKV病毒质组织和病毒产生的作用。我们表明ZIKV感染后形成环形病毒质,MT在病毒质核心和病毒质周围组织。我们表明,MT是必要的病毒质组织和影响感染性病毒的生产。此外,中心体和高尔基体MTOC与病毒质密切相关,并且中心体协调ZIKV病毒质环形结构的组织。令人惊讶的是,病毒质的形成和病毒的生产没有显着受损时,感染的细胞没有中心体和受损的高尔基MTOC,我们表明,MT锚定在这些细胞的病毒质表面。我们建议,病毒质是一个网站的MT组织,并组织在病毒质的MT是足够的有效的病毒生产。
Zika virus (ZIKV) became a global health concern in 2016 due to its links to congenital microcephaly and other birth defects. Flaviviruses, including ZIKV, reorganize the endoplasmic reticulum (ER) to form a viroplasm, a compartment where virus particles are assembled. Microtubules (MTs) and microtubule-organizing centers (MTOCs) coordinate structural and trafficking functions in the cell, and MTs also support replication of flaviviruses. Here we investigated the roles of MTs and the cell’s MTOCs on ZIKV viroplasm organization and virus production. We show that a toroidal-shaped viroplasm forms upon ZIKV infection, and MTs are organized at the viroplasm core and surrounding the viroplasm. We show that MTs are necessary for viroplasm organization and impact infectious virus production. In addition, the centrosome and the Golgi MTOC are closely associated with the viroplasm, and the centrosome coordinates the organization of the ZIKV viroplasm toroidal structure. Surprisingly, viroplasm formation and virus production are not significantly impaired when infected cells have no centrosomes and impaired Golgi MTOC, and we show that MTs are anchored to the viroplasm surface in these cells. We propose that the viroplasm is a site of MT organization, and the MTs organized at the viroplasm are sufficient for efficient virus production.
