For example, mAbs targeting the programmed death receptor axis PD-1/PD-L1, T cell immunoglobulin and ITIM domain (TIGIT), lymphocyte activation gene-3 (LAG-3), and T cell immunoglobulin mucin-3 (TIM-3) are known to enhance NK cell function and improve anti-tumor responses (40–43). Here, LAG3 is linked to neoplasm.
