PD-1 Gene Editing    

PD-1 (programmed cell death protein 1), also named CD279, is an inhibitory receptor expressed by all T cells during activation to control the body's immune response and is one of the most important immunity checkpoints. PD-1 inhibits T cell inflammatory activity and promotes self-tolerance, thereby regulating the immune system's response to human cells. Thus, PD-1 modulates T cell effector functions in a variety of physiological responses, including acute and chronic infections, cancer and autoimmunity, and immune homeostasis (Figure 1).

Figure 1: Effect of PD-1 on major signaling pathways in T cells

Studies have shown that PD-1 signaling is one of the main factors in human cancer immune escape. PD-L1 is a PD-1 receptor located on the surface of normal cells and cancer cells. When PD-1 binds to PD-L1, it helps prevent T cells from killing other cells, including cancer cells. Monoclonal antibodies that target PD-1 or PD-L1 block this binding and enhance the immune response of T cells to cancer cells. These drugs show significant efficacy in the treatment of certain cancers, including cutaneous melanoma, non-small cell lung cancer, kidney cancer, bladder cancer, head and neck cancer, and Hodgkin's lymphoma. In addition, PD-1 signaling shows great potency in other immune diseases treatment, such as AIDS. But one problem with all these drugs is that they can cause the immune system to attack certain normal organs of the body, which may cause serious side effects in some people. There is still a long way to go for the development and clinical application of anticancer drugs targeting PD-1 signaling.
