Background: Melanoma is widely recognized to be an immunogenic tumor that often contains tumor-infiltrating lymphocytes (TILs) in the tumor microenvironment (TME).During cancer progression, expression
T cell coinhibitory immune checkpoints, such as PD-1 or BTLA, are bona fide targets in cancer therapy. Here we used a human T cell reporter line to measure transcriptome changes mediated by PD-1 and B
