流感病毒呼吸道黏膜感染免疫防御机制的研究进展

Recent Advances of Defense Mechanisms Against Influenza Virus Infection in The Respiratory Tract

流感发病率高,流行广,是由流感病毒通过呼吸道黏膜感染引起的重要传染病。呼吸道黏膜不仅是流感病毒的感染部位,也是防御病毒感染的部位。在流感病毒侵入机体后天然免疫系统立即作出应急反应,如果病毒逃过了非特异性免疫系统,就会被获得性免疫系统加以反应性清除。

Influenza virus is a globally important respiratory pathogen which causes a high degree of morbidity and mortality annually. The respiratory tract mucosa is not only the site of infection for influenza viruses but also the site of defense against virus infection. Viruses are initially detected and destroyed non-specifically by innate immune mechanisms, but if the viruses escape the early defense mechanisms, they are detected and eliminated specifically by adaptive immune mechanisms.
