摘要:

抗体依赖性增强作用(ADE)已成为病毒致病机制、抗体药物治疗和疫苗开发的关键因素。在特定情况下,抗体能介导冠状病毒与其病毒受体或Fc受体(FcR)结合,增强病毒感染能力,进而导致ADE。ADE的发生受病毒和宿主一系列复杂因素的调节,如病毒包膜蛋白结构、与受体的亲和力、抗体水平等。文章综述了近年来ADE在多种人冠状病毒研究中的最新进展,为疫苗设计、抗体相关药物及免疫治疗等提供一定的理论依据。

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.
