Webplexes formed at steady state (ant:IgG:IgG:FcgR-FcgR) as a function of concentration and binding of IgG1, IgG2, IgG3, and IgG4 to antigen and FcgR(Figure 1). The model assumed two IgG binding sites per antigen protein to represent the simplest complex that reﬂects activation through FcgR cross-linking. The receptor inhibits the functions of activating FcγRs, such as phagocytosis and pro-inflammatory cytokine release, mainly by clustering of FCGR2B with different activating FCGR receptors or with the BCR by immune complexes. The phosphorylated ITIM of FcγRIIB recruits the inositol phosphatases SHIP1 and SHIP2, which inhibit the Ras activation, downregulate MAPK activity and reduce PLCγ function and lead to de… bolle mojo goggles white
