描述（Description）
The CHO/Human CD16a (158V) Stable Cell Line was engineered to express full length human CD16a receptor mutated to a Valine (V) at amino acid 158 with different levels of CD16a (158V) expression (High, Medium, Low), which can be used to test agonist antibody whether in a CD16a (158V)-dependent manner to strengthen the agonistic activity. When co-cultured with Human 4-1BB Reporter Cell and anti-4-1BB agonist antibody, the anti-4-1BB antibody can be crosslinked, thereby strengthening 4-1BB pathway-activated luminescence.

Receptor Assay
Expression analysis of human CD16a on CHO/Human CD16a (158V) Stable Cell Line by FACS.
Cell surface staining using PE-labeled anti-human CD16a antibody was performed on CHO/Human CD16a (158V) Stable Cell Line with different expression levels: CHO/Human CD16a (158V) Stable Cell Line (Low Expression); CHO/Human CD16a (158V) Stable Cell Line (Medium Expression); CHO/Human CD16a (158V) Stable Cell Line (High Expression).

背景（Background）
CD16 is a low affinity Fc receptor, and has been identified as Fc receptors FcγRIIIa (CD16a) and FcγRIIIb (CD16b). These receptors bind to the Fc portion of IgG antibodies. CD16 encoded by two different highly homologous genes in a cell type-specific manner.CD16 is found on the surface of natural killer cells, neutrophil polymorphonuclear leukocytes, monocytes and macrophages. CD16a antigen is also known as Low affinity immunoglobulin gamma Fc region receptor III-A, Fc-gamma RIII-alpha. CD16b is a low-affinity, GPI-linked receptor expressed by neutrophils and eosinophils, whereas CD16a is an intermediate affinity polypeptide-anchored transmembrane glycoprotein expressed natural killer cells, macrophages, subpopulation of T-cells, immature thymocytes and placentaltrophoblasts.CD16a is involved in phagocytosis, secretion of enzymes and inflammatory mediators, antibodydependent cytotoxicity and clearance of immune complexes. Aberrant expression or mutations of CD16a is implicated in susceptibility to recurrent viral infections, systemic lupus erythematosus, and alloimmune neonatal neutropenia.
