Some tumor cells haveexploited this by developing partner proteins, such as programmeddeath-ligand 1 (PD-L1), that can bind to checkpoints to evade attack.Correspondingly, a promising class of T cell-based cancer immunotherapies,ICT, has been elaborated to block one or multiple receptors usingantibodies, thereby reversing the “off” signals inducedby tumor cells and reinvigorating the functions of T cells. This evidence concerns the gene CD274 and neoplasm.
