摘要
包膜病毒指具有一层脂质双层膜的病毒,如流感病毒、冠状病毒等,这些包膜病毒每年在世界范围内导致许多严重的疾病,严重威胁人类健康.使用抗病毒药物是预防与治疗病毒感染的主要策略,芽胞杆菌(Bacillus)及其代谢物能够抑制多种包膜病毒的感染.本文综述了芽胞杆菌代谢的粗提物、肽、酶、胞外聚合物、小双链RNA和热灭活的枯草芽胞杆菌孢子在抗包膜病毒感染中发挥的重要作用,其机制是通过直接破坏病毒包膜、阻止膜融合、与病毒基因组RNA直接配对、催化裂解病毒RNA、激活天然免疫反应等对抗病毒,期望为包膜病毒的持续预防和治疗提供参考.
Abstract
Enveloped viruses refer to viruses with a lipid bilayer membrane,such as influenza viruses,coronaviruses,etc.,which cause many serious diseases worldwide annually and seriously threaten human health.The use of antiviral drugs is the main strategy for the prevention and treatment of viral infections,and Bacillus and its metabolites can in-hibit infection with a variety of enveloped viruses.This article reviews the important roles played by crude extracts,peptides,enzymes,extracellular polymers,small double-stranded RNA and heat-inactivated Bacillus subtilis spores in anti-enveloped virus infection,and the mechanism is to directly destroy the viral envelope,prevent membrane fusion,directly pair with viral genomic RNA,catalyze the lysis of viral RNA,activate the natural immune response,etc.,hopefully to provide a reference for the continuous prevention and treatment of enveloped virus.
