Cd16 function
WebMonocyte subset markers Human monocyte markers Expression of CD14, CD16 (Fcγ RIII), CD64 (Fcγ RI), and the chemokine receptors CD192 and CX3CR1 define human peripheral blood monocyte populations into three different subsets: classical, intermediate, and nonclassical ( Table 1 ). WebCD16 exists as a transmembrane form in NK cells, macrophages and cultured monocytes with a 25 amino acid cytoplasmic tail which further connects with other receptors. The transmembrane form binds complexed IgG and mediates phagocytosis and antibody-dependent cellular cytotoxicity (ADCC). [ 6] [ 7] Target description
