Research progress on mechanism of antibody-dependent enhancement / 中国人兽共患病学报

ABSTRACT

In many pathogens infection,especially virus,antibody-dependent enhancement(ADE) can aggravate the infection and lead to severe diseases.In this immunopathological phenomenon,virus-specific antibodies enhance the entry of virus into monocytes,macrophages and granulocytic cells and even the replication of virus through different mechanism.This phenomenon has been reported in numerous pathogens including virus,bacteria and parasite and the mechanisms of ADE vary from different species.Further study of ADE can promote the vaccine research and development to make the most use of vaccine and prevent human body from pathogens,which will be helpful to control the spread of pathogens including Zika virus.In the present review,we review the research progress of ADE mechanism in recent years,including antibodies mediating,receptors mediating,complement mediating,viral proteins mediating and cellular mediating ADE.In addition,dengue virus,human immunodeficiency virus,Coxsackie virus,Ebola virus,Zika virus and other pathogens will be illustrated respectively.This review provides insights on the different mechanism of ADE in different pathogens.
