通过与不同类型的Fcγ受体(Fcγ R)的特异性相互作用,IgG的Fc结构域介导影响先天性和适应性反应的广泛免疫功能。最近的研究表明,IgG Fc-Fc γR相互作用在免疫应答过程中受到动态调节,一方面通过控制Fc相关聚糖结构和IG亚类组成,另一方面通过免疫细胞上的选择性FcγR表达,两者共同决定了IgG以细胞类型特异性方式与FcγR家族特异性成员相互作用的能力。在这里,我们提出了一个框架,综合目前的理解FcγR途径的抗体和T细胞反应的诱导和调节的贡献。在此背景下,我们讨论了基于Fc-Fc γR相互作用的免疫调节特性引发广泛和有效免疫应答的疫苗接种策略。
Through specific interactions with distinct types of Fcγ receptors (FcγRs), the Fc domain of IgG mediates a wide spectrum of immunological functions that influence both innate and adaptive responses. Recent studies indicate that IgG Fc-FcγR interactions are dynamically regulated during an immune response through the control of the Fc-associated glycan structure and Ig subclass composition, on the one hand, and selective FcγR expression on immune cells on the other, which together determine the capacity of IgG to interact in a cell type specific manner with specific members of the FcγR family. Here we present a framework that synthesizes the current understanding of the contribution of FcγR pathways to the induction and regulation of antibody and T-cell responses. Within this context, we discuss vaccination strategies to elicit broad and potent immune responses based on the immunomodulatory properties of Fc-FcγR interactions.
