Fc-Gamma Receptor II

**Semantic type:** Amino Acid, Peptide, or Protein|Immunologic Factor|Receptor

**Definition:** A family of low affinity receptors for aggregates of gamma immunoglobulins (IgG). These receptors are expressed on the surface of monocytes, macrophages, polymorphonuclear cells, natural killer cells, T- and B-lymphocytes, and platelets. IgG binding initiates cellular responses against foreign pathogens and soluble antigens, induces phagocytosis of antigen-antibody complexes, and modulates antibody production.
