| 1 | FOLR1-induced folate deficiency reduces viral replication via modulating APOBEC3 family expression显示文摘Folate receptor alpha(FOLR1)is vital for cells ingesting folate(FA).FA plays an indispensable role in cell pro-liferation and survival.However,it is not clear whether the axis of FOLR1/FA has a similar function in viral replication.In this study,we used vesicular stomatitis virus(VSV)to investigate the relationship between FOLR1-mediated FA deficiency and viral replication,as well as the underlying mechanisms.We discovered that FOLR1 upregulation led to the deficiency of FA in HeLa cells and mice.Meanwhile,VSV replication was notably sup-pressed by FOLR1 overexpression,and this antiviral activity was related to FA deficiency.Mechanistically,FA deficiency mainly upregulated apolipoprotein B mRNA editing enzyme catalytic subunit 3B(APOBEC3B)expression,which suppressed VSV replication in vitro and in vivo.In addition,methotrexate(MTX),an FA metabolism inhibitor,effectively inhibited VSV replication by enhancing the expression of APOBEC3B in vitro and in vivo.Overall,our present study provided a new perspective for the role of FA metabolism in viral infections and highlights the potential of MTX as a broad-spectrum antiviral agent against RNA viruses. | Jing Wu Yajing Han Ruining Lyu Fang Zhang Na Jiang Hongji Tao Qiao You Rui Zhang Meng Yuan Waqas Nawaz Deyan Chen Zhiwei Wu | 2023 | Virologica Sinica2023，38，3： | 0 |
