Background: Fc gamma RIII (CD16)
Fc gamma RIIIA/CD16a is expressed as a transmembrane protein on NK cells and on a subset of monocytes, macrophages, CD4+T cells, basophils, and mast cells (1-3). Fc gamma RIIIB/CD16b is primarily expressed on neutrophils as a glycosylphosphatidylinositol (GPI)-anchored protein but is also expressed on a subset of basophils and can be induced on eosinophils (1-3). The soluble form of CD16 (sCD16) which is often produced following exposure to inflammatory signals and protein shedding via metalloproteinases (3). Reduced sCD16 levels have been found in patients with multiple myeloma (3).
Activating NK cell receptor function has been harnessed for its potential in tumor immunotherapy (6). One immunotherapy strategy is using bi- and tri-specific NK cell engagers (BiKE and TriKE) to target the Fc gamma RIIIA/CD16a receptor with tumor-associated antigens to stimulate a cytotoxic response and mount an attack on tumor cells (6). CD16a is also capable of antibody dependent cellular cytotoxicity (ADCC) through recognition of antibodies bound to target cells (6-7). CD16-induced NK cell activation allows for NK co-receptor expression including stimulatory receptors like CD137 or inhibitory receptors like TIGIT and PD-1, which serve as additional regulatory checkpoints during ADCC (7). Therapeutic antibodies for cancer treatment like rituximab or trastuzumab can be recognized by Fc gamma RIIIA/CD16a to activate NK cell-mediated killing of tumor cells (6-7).
