FCGR3A and cancer: The CD16 receptor, also known as FcγRIIIA, is expressed by immune cells such as NK cells and monocytes/macrophages and plays a role in the antibody-dependent cellular cytotoxicity (ADCC) against opsonized (antibody-coated) cells, such as virus-infected cells or cancer cells, through its binding capabilities to the Fc part of the G-Immunoglobulins [48].
