J CLIN INVEST: 寨卡病毒感染人类睾丸组织和生殖细胞

2018-08-14 MedSci MedSci原创

寨卡病毒(ZIKV)是一种经蚊媒传播的致畸型黄病毒,可通过性行为从男性传播到女性。精液中高病毒载量和持续的病毒脱落表明ZIKV可在人类男性生殖道内复制,但其目标器官尚不清楚。研究人员通过器官型培养的体外感染,证明了ZIKV在人类睾丸组织中复制,并感染了广泛的细胞类型,包括生殖细胞,还确认献血者的精液感染了ZIKVZIKV对人类睾丸外植体的形态学和激素分泌无明显影响。在睾丸外植体中,ZIKV感染引起了广泛的抗病毒反应,但干扰素没有上调,促炎反应较小,也没有细胞病理效应。最后,研究人员研究了小鼠睾丸中的ZIKV感染,并将其与人类感染进行了比较。这项研究为ZIKV如何在精液中持续存在和改变精液参数提供了关键的见解,同时也为抗病毒药物的测试提供了宝贵的工具。
