Yuqiang Zhang, Zhe Li, Zhi Ye, Yan Xu, Binbin Wang, Congcong Wang, Yunpeng Dai, Jinfeng Lu, Boxun Lu, Wanju Zhang & Yang Li
The RNA interference (RNAi) pathway directs an important antiviral immunity mechanism in plants and invertebrates. Recently, we and others have demonstrated that the antiviral RNAi response is also conserved in mammals, at least to five distinct RNA viruses, including Zika virus (ZIKV). ZIKV may preferentially infect neuronal progenitor cells (NPCs) in the developing foetal brain. Ex vivo ZIKV infection induces RNAi-mediated antiviral response in human NPCs, but not in the more differentiated NPCs or somatic...
