MERS-CoV nsp1 regulates autophagic flux via mTOR signaling and dysfunctional lysosomes

Yujie Feng, Zhaoyi Pan, Zhihui Wang, Zhengyang Lei, Songge Yang, Huajun Zhao, Xueyao Wang, Yating Yu, Qiuju Han & Jian Zhang
Autophagy, a cellular surveillance mechanism, plays an important role in combating invading pathogens. However, viruses have evolved various strategies to disrupt autophagy and even hijack it for replication and release. Here, we demonstrated that Middle East respiratory syndrome coronavirus (MERS-CoV) non-structural protein 1(nsp1) induces autophagy but inhibits autophagic activity. MERS-CoV nsp1 expression increased ROS and reduced ATP levels in cells, which activated AMPK and inhibited the mTOR signaling pathway, resulting in autophagy induction. Meanwhile, as...
