Abstract:

Antibody-dependent enhancement(ADE) of viral entry has been a major concern for epidemiology,vaccine development and antibody-based drug therapy. ADE of coronavirus replication is believed to occur when antibodies mediate coronavirus to bind to its viral receptor or Fc receptor(FcR) to enhance viral infection in some certain cases. ADE is regulated by a series of complex factors of the virus and the host,such as the structure of spike protein,the affinity with receptor and the titer of antibody of coronavirus. In this review,the present advances of ADE in human coronaviruses were discussed to provide reference for the subsequent vaccine design,antibody-related drugs,and immunotherapy.

Key words: Coronavirus, Severe acute respiratory syndrome-related coronavirus, Middle east respiratory syndrome-related coronavirus, Severe acute respiratory syndrome coronavirus 2, Antibody-dependent enhancement, Vaccines
