Zika virus (ZIKV) is an arthropod-borne virus that belongs to the Flavivirus genus and is principally transmitted by mosquitoes. ZIKV infection often causes no or only mild symptoms, but it can also trigger severe consequences, including microcephaly in infants and Guillain-Barré syndrome, uveitis, and neurologic manifestations in adults. There is no ZIKV vaccine or treatment currently approved for clinical use. The primary target of ZIKV infection has been recognized as the maternal placenta, with vertical transmission to the fetal brain. However, ZIKV can also spread to multiple tissues in adults, including the sexual organs, eyes, lymph nodes, and brain. Since numerous studies have indicated that there are slightly different tissue-specific pathologies in each animal model of ZIKV, the distinct ZIKV tropism of a given animal model must be understood to enable effective vaccine development. Here, we comprehensively discussed the tissue specificity of ZIKV reported in each animal model depending on the genetic background and route of administration. This review should facilitate the selection of appropriate animal models when studying the fundamental pathogenesis of ZIKV infection, thereby supporting the design of optimal preclinical and clinical studies for the development of vaccines and therapeutics.
寨卡病毒(ZIKV)是一种节肢动物传播病毒,属于黄病毒属,主要通过蚊子传播。寨卡病毒感染通常不会引起症状或仅引起轻微症状,但也可能引发严重后果,包括婴儿小头畸形、格林-巴利综合征、葡萄膜炎以及成人的神经表现。目前尚无经临床批准使用的寨卡病毒疫苗或治疗方法。寨卡病毒感染的主要靶标被认为是母体胎盘,可垂直传播至胎儿大脑。然而,寨卡病毒在成人中也可传播至多个组织,包括性器官、眼睛、淋巴结和大脑。由于众多研究表明,在寨卡病毒的每种动物模型中都存在略有不同的组织特异性病理情况,因此必须了解特定动物模型独特的寨卡病毒嗜性,才能有效开发疫苗。在此,我们根据遗传背景和给药途径,全面讨论了每种动物模型中报道的寨卡病毒的组织特异性。本综述应有助于在研究寨卡病毒感染的基本发病机制时选择合适的动物模型,从而为疫苗和治疗药物开发的最佳临床前和临床研究设计提供支持。
