Material Safety Data Sheet (MSDS)

Fc gamma receptors (FcγRs) are expressed on a host of different innate and adaptive immune cell-surfaces, including the leukocyte surface and interact with the Fc domain of immunoglobulin G (IgG) antibodies to mediate inflammatory responses.

Interaction of FcγRs with IgG immune complexes initiates intracellular signalling pathways that lead to a variety of either immunostimulatory or immunosuppressive downstream events, including cytokine/chemokine production. FcγRs are involved in modulating a range of processes, including antibody production, antigen presentation, and activation of B cells and innate immune effector cells.

In humans; five genes FCGR2A, FCGR2B, FCGR2C, FCGR3A, and FCGR3B, located in an 82.5‐kb segmental tandem duplication on chromosome 1q23.3, encode five low‐affinity receptors FcγRIIa, FcγRIIb, FcγRIIc, FcγRIIIa and FcγRIIIb. These genes have extensive copy‐number variation (CNV) and FcγR genetic variation can have significant implications on how the immune system reacts to different stimuli. Deletions of FCGR3B have been suggested to increase the risk of inflammatory diseases such as systemic lupus erythematosus and rheumatoid arthritis (RA).
