| Abstract |
Antibody drugs are one of the most important therapeutic modalities in cancer treatment. Antibody drugs for canine cytotoxicity have been developed, and the most important way to evaluate the function of antibody drugs in vitro is to measure the antibody-dependent cellular cytotoxicity (ADCC) activity. However, a good method for measuring the ADCC activity of antibody drugs for dogs has not yet been developed. This study generated a cell line of NK-92 cells, a human natural killer cell line, transfected with canine CD16 and γ-chain as effector cells. A20 cells expressing canine CD20 were used as target cells, and a system for ADCC activity was established using an anti-dog CD20 antibody. The assay generated very consistent results. This is an applicable method for measuring canine ADCC activity and can be used for various antigen-antibody combinations to develop canine antibody drugs with cytotoxic activity in the future.
