Blockade of intrinsic PD-1 promotes survival, chemo resistance and tumor growth in human colon cancer
The PD-1 immune checkpoint is the target for cancer immunotherapy, which has recently revolutionized cancer treatment approaches. Interestingly, PD-1 is not only expressed by immune cells but also by cancer cells, however contradictory reports are available regarding its significance. The role and P...

Human colon cancer cells HT29, HCT116, LoVo robustly expressed PD-1. PD-1 signaling significantly decreased proliferation and promoted apoptosis in PD1+human colon cancer cells. The human anti-PD-1, Nivolumab (NIVO) ptomoted proliferation through pERK/pAKT signaling, reduced apoptosis and protected ...

Cancer treatment has been revolutionized by immune checkpoint inhibitors, which regulate immune cell function by blocking the interactions between immune checkpoint molecules and their ligands. The interaction between programmed cell death-1 (PD-1) and programmed cell death-ligand 1 (PD-L1) is a tar...
