Abstract γδ T cells can kill cancer cells via antibody-independent cytotoxicity (AIC) and antibody-dependent cellular cytotoxicity (ADCC). A better understanding of how these cytotoxic mechanisms are affected by different cancer cells and different T-cell donors could help identify improved immunotherapeutic strategies. To …
