FCGR2B and staphylococcus aureus infection: IgG binding activates FcγRs and FcγRIIb, mainly leading to endocytosis and internalization of immune complexes; therefore, these studies corroborate our finding of “IgG binding,” “clathrin-coated endocytic vesicle membrane,” and “clathrin-coated endocytic vesicle” in our GO analysis and the enriched pathways “Fc gamma R-mediated phagocytosis” and “Staphylococcus aureus infection” in the KEGG analysis.
