CSPG4 and melanoma: Antibodies with the same binding specificity to melanoma‐associated antigen CSPG4 (also known as MCSP) but differing in the Fc domains (IgG1 or IgG4) were tested for effector function; IgG1 mediated significantly higher levels of antibody‐dependent cell‐mediated phagocytosis (ADCP) of melanoma by monocytes than IgG4 (Karagiannis et al., 2013).
