最近的研究已经揭示了Fc γ受体(Fcγ R)在针对流感病毒的广泛免疫中的多种作用。激活FcγR途径可用于提供由非中和性抗HA IgG介导的保护,并增加广泛中和性抗HA IgG和抗NA IgG的效价。可以靶向单独的FcγR途径,以增强季节性流感病毒疫苗引发的抗体应答的广度。在这里,我们回顾了目前对广泛流感免疫中FcγR途径的理解,并提出了绕过人与人之间FcγR信号传导异质性的机制,这种异质性源于IgG Fc结构域结构库的差异。
Recent studies have revealed multiple roles for Fc gamma receptors (FcγRs) in broad immunity against influenza viruses. Activating FcγR pathways can be harnessed to confer protection mediated by non-neutralizing anti-HA IgGs and to increase the potency of broadly neutralizing anti-HA IgGs and of anti-NA IgGs. Separate FcγR pathways can be targeted to enhance the breadth of antibody responses elicited by seasonal influenza virus vaccines. Here, we review the current understanding of FcγR pathways in broad influenza immunity and suggest mechanisms to bypass FcγR signaling heterogeneity among people that arises from distinctions in structural repertoires of IgG Fc domains.
