WebHuman natural killer (NK) cells can be subdivided into different populations based on the relative expression of the surface markers CD16 and CD56. The two major subsets are CD56 (bright) CD16 (dim/) (-) and CD56 (dim) CD16 (+), respectively. In this review, we will focus on the CD56 (bright) NK cell subset. WebAntibody-dependent cellular cytotoxicity (ADCC), also called antibody-dependent cell-mediated cytotoxicity, is an immune mechanism through which Fc receptor-bearing effector cells can recognize and kill antibody-coated target cells expressing tumor- or pathogen-derived antigens on their surface.
