Summary	Receptors for the Fc portion of human IgG (Fc gamma receptors) can be divided into three classes as Fc gamma RI (CD64), RII (CD32), and RIII (CD16). Each of these proteins may be coded by multiple genes and exist in different isoforms. Fc gamma RI or CD64 proteins can bind Fc portion of human IgG with high affinity and play important role in early immune response. In contrast CD16 and CD32 bind human IgG with low affinity and can only recognize the IgG aggregates with multivalent antigens. Human CD64 is expressed constitutively on macrophages and monocytes and its expression can be induced by IFNg or G-CSF on polymorphonuclear leukocytes.
