1Cholesterol-25-Hydroxylase Suppresses Seneca Valley Virus Infection via Producing 25-Hydroxycholesterol to Block Adsorption Procedure显示文摘Cholesterol-25-hydroxylase(CH25 H)is a membrane protein associated with endoplasmic reticulum,and it is an interferon-stimulated factor regulated by interferon.CH25 H catalyzes cholesterol to produce 25-hydroxycholesterol(25 HC)by adding a second hydroxyl to the 25 th carbon atom of cholesterol.Recent studies have shown that both CH25 H and 25 HC could inhibit the replication of many viruses.In this study,we found that ectopic expression of CH25 H in HEK-293 T and BHK-21 cell lines could inhibit the replication of Seneca Valley virus(SVV)and that there was no species difference.On the other hand,the knockdown of CH25 H could enhance the replication of SVV in HEK-293 T and BHK-21 cells,indicating the importance of CH25 H.To some extent,the CH25 H mutant without hydroxylase activity also lost its ability to inhibit SVV amplification.Further studies demonstrated that 25 HC was involved in the entire life cycle of SVV,especially in repressing its adsorption process.This study reveals that CH25 H exerts the advantage of innate immunity mainly by producing 25 HC to block virion adsorption.Hui Li Zekai Zhao Xiangmin Li Liuxing Qin Wei Wen Huanchun Chen Ping Qian 2021Virologica Sinica2021,36,5:0
