Research progress in mechanism of natural killer cells in influenza
Influenza virus causes high morbidity and mortality every year,which is posing a serious threat to global public health security.Influenza viruses possess the ability to evade host immune responses and evade the vaccine protection.Therefore,it is imperative to develop drugs or vaccines targeting mechanisms of host cell to reduce the incidence rate of severe illness and mortality.Natural killer cells(NK cells)can quickly kill the influenza virus infected cells in a non allergenic state,also have immune regulation and memory effects,which brings hope for the prevention and treatment of influenza viruses.This article reviews the mech-anism of NK cells and their immune activation in influenza,in order to provide reference for the researches of new drugs or vaccines for preventing and treating influenza.
