Immune Checkpoint Proteins

The immune checkpoint (ICP) molecules refer to ligand-receptor pairs that exert inhibitory or stimulatory effects on immune responses. Most of the ICP proteins that have been described are expressed on cells of the adaptive immune system, particularly on T cells, and of the innate immune system. ICPs act as important immune regulators in maintaining immune homeostasis and preventing autoimmunity.
Some cancer cells can bind co-inhibitory receptor molecules to limit normal anti-tumor immune responses, thus assisting in immune escape. Immune checkpoint therapy for cancer encompasses strategies that target these regulatory pathways to reinvigorate the anti-tumor function of immune cells. The most widely studied inhibitory checkpoint pathway consisting of cytotoxic T lymphocyte-associated molecule-4 (CTLA-4), programmed cell death receptor-1 (PD-1), and programmed cell death ligand-1 (PD-L1).
