Background

IgG Fc receptor (Fc γ R) is a member of the Ig superfamily, which plays a role in activating or inhibiting immune response. Human Fc γ Rs is identified as three types: RI (CD64), RII (CD32) and RIII (CD16). CD16 is a low-affinity Fc receptor, which has been identified as Fc receptor Fc γ RIII (a (CD16a) and Fc γ RIIIb (CD16b). These receptors bind to the Fc portion of the IgG antibody and are encoded by two different highly homologous genes in a cell type-specific manner. CD16b, also known as FCGR3b and FCG3b, is specifically expressed by neutrophils and stimulated eosinophils. CD16b is a low affinity receptor of immunoglobulin Fc γ region. CD16b binds composite or aggregated IgG and monomer IgG. CD16b could not mediate antibody-dependent cytotoxicity and phagocytosis.
