DEF

Specific cell-surface receptors for antigen-antibody complexes or aggregated immunoglobulins that bind a site in the Fc portion of the immunoglobulin molecule and may exhibit specificity for particular immunoglobulin classes. Fc receptors are found on B cells, K cells, macrophages, neutrophils, and eosinophils, and, during some developmental stages, on T cells; those on K cells, macrophages, and neutrophils bind to opsonizing antibodies bound to antigens and trigger phagocytosis of the antigen.
