In a separate in vivo mouse tumor model established by injection of J82-ESO1, a PD-L1-positive bladder cancer line transfected with NY-ESO1 antigen, specific TCR-Ts against human leukocyte antigen HLA-A2-restricted NY-ESO1 with or without ER were infused for suppression of tumor growth. This evidence concerns the gene CD274 and urinary bladder cancer.
