Immune Checkpoint Proteins

Immune checkpoints have been playing a significant role in cancer immunotherapy. They are a serious of co-stimulatory and inhibitory signals for regulating the antigen recognition. The cancer cells cleverly escape from immunity by dysregulating immune checkpoint signaling. So agonists of co-stimulatory signals or antagonists of inhibitory signals function as good ways for cancer therapy. Over these years, remarkable successes have been achieved in immune checkpoint therapy : CTLA-4 and PD1- PD-L1 inhibitors have already been approved for cancer therapy with effective efficacy. Multiple additional researches on other immune checkpoints have also stepped into clinical trials, predicting new hope for conquering cancer.
