Zika virus (ZIKV), despite being discovered six decades earlier, became a major health concern only after an epidemic in French Polynesia and an increase in the number of microcephaly cases in Brazil. Substantial evidence has been found to support the link between ZIKV and neurological complications in infants. The virus targets various cells in the brain, including radial glial cells, neural progenitor cells (NPCs), astrocytes, microglial and glioblastoma stem cells. It affects the brain cells by exploiting different mechanisms, mainly through apoptosis and cell cycle dysregulation. The modulation of host immune response and the inflammatory process has also been demonstrated to play a critical role in ZIKV induced neurological complications. In addition to that, different ZIKV strains have exhibited specific neurotropism and unique molecular mechanisms. This review provides a comprehensive and up-to-date overview of ZIKV-induced neuroimmunopathogenesis by dissecting its main target cells in the brain, and the underlying cellular and molecular mechanisms. We highlighted the roles of the different ZIKV host factors and how they exploit specific host factors through various mechanisms. Overall, it covers key components for understanding the crosstalk between ZIKV and the brain.
寨卡病毒(ZIKV)虽然早在六十年前就被发现,但直到法属波利尼西亚的一次疫情以及巴西小头症病例数量的增加,才成为一个主要的健康问题。有大量证据表明寨卡病毒与婴儿的神经并发症之间存在关联。该病毒针对大脑中的各种细胞,包括放射状胶质细胞、神经祖细胞(NPC)、星形胶质细胞、小胶质细胞和神经胶质瘤干细胞。它通过多种机制影响脑细胞,主要通过细胞凋亡和细胞周期失调。宿主免疫反应和炎症过程的调节也被证明在寨卡病毒引起的神经并发症中起着关键作用。此外,不同的寨卡病毒株表现出特定的神经嗜性和独特的分子机制。本综述通过剖析大脑中的主要靶细胞以及潜在的细胞和分子机制,全面而详尽地概述了寨卡病毒引起的神经免疫发病机制。我们强调了不同寨卡病毒宿主因子的作用,以及它们如何通过各种机制利用特定的宿主因子。总的来说,它涵盖了理解寨卡病毒与大脑相互作用的关键组成部分。
