Abstract

Zika virus (ZIKV) cases continue to be reported, and no vaccine or specific antiviral agent has been approved for the prevention or treatment of infection. Though ZIKV is primarily transmitted by mosquitos, cases of sexual transmission and prolonged viral RNA presence in semen have been reported. In this observational study, we report the mucosal responses to sub-cutaneous and mucosal ZIKV exposure in cynomolgus macaques during acute and late chronic infection. Subcutaneous challenge induced a decrease in the growth factor VEGF in colorectal and cervicovaginal tissues 100 days post-challenge, in contrast to the observed increase in these tissues following vaginal infection. This different pattern was not observed in the uterus, where VEGF was upregulated independently of the challenge route. Vaginal challenge induced a pro-inflammatory profile in all mucosal tissues during late chronic infection. Similar responses were already observed during acute infection in a vaginal tissue explant model of ex vivo challenge. Non-productive and productive infection 100 days post-in vivo vaginal challenge induced distinct proteomic profiles which were characterized by further VEGF increase and IL-10 decrease in non-infected animals. Ex vivo challenge of mucosal explants revealed tissue-specific modulation of cytokine levels during the acute phase of infection. Mucosal cytokine profiles could represent biosignatures of persistent ZIKV infection.

摘要

寨卡病毒(ZIKV)感染病例仍在不断报告,目前尚无获批用于预防或治疗该病毒感染的疫苗或特异性抗病毒药物。虽然寨卡病毒主要通过蚊子传播,但也有性传播病例以及精液中病毒RNA长期存在的报道。在这项观察性研究中,我们报告了食蟹猕猴在急性和慢性感染后期,皮下和黏膜暴露于寨卡病毒后的黏膜反应。皮下攻击后100天,结直肠和宫颈阴道组织中的生长因子血管内皮生长因子(VEGF)减少,而阴道感染后这些组织中该因子增加。子宫中未观察到这种不同模式,其中VEGF的上调与攻击途径无关。阴道攻击在慢性感染后期的所有黏膜组织中诱导了促炎特征。在体外攻击的阴道组织外植体模型的急性感染期间已经观察到类似反应。体内阴道攻击后100天的非生产性和生产性感染诱导了不同的蛋白质组学特征,其特征是未感染动物中VEGF进一步增加和白细胞介素-10减少。黏膜外植体的体外攻击揭示了感染急性期细胞因子水平的组织特异性调节。黏膜细胞因子特征可能代表寨卡病毒持续感染的生物标志物。
