The following changes were made to the 7/20 revision of this document: The programmed cell death protein 1 receptor (PD-1) receptor was first described in the early 1990s given its expression during induction of apoptosis in a T-cell hybridoma [1, 2].Since its initial discovery several groups have identified that engagement of PD-1 through its ligand, programmed death ligand 1 (PD-L1), negatively regulates T-cell-mediated immune responses [3,4,5,6]. As previously mentioned, while highly effective, anti-PD1/PDL1 therapies engender little to no benefit for many patients, and patients can be stratified as being sensitive, or as displaying either primary or acquired resistance , .For example, the posterchild for success in anti-PD1 therapy, and also the example for which clinical data are most mature, is melanoma.
