Applications: Screen for activators or inhibitors of PD-1 signaling in a cellular context Characterize the biological activity of PD-1 and its interactions with ligands
Background: The binding of Programmed Cell Death Protein 1 (PD-1), a receptor expressed on activated Tcells,to its ligands, PD-L1 and PD-L2, negatively regulates immune responses. The PD-1ligands are found on most cancers, and PD-1:PD-L1/2 interaction inhibits T cell activity andallows cancer cells to escape immune surveillance. The PD-1:PD-L1/2 pathway is also involvedin regulating autoimmune responses, making these proteins promising therapeutic targets for anumber of cancers, as well as multiple sclerosis, arthritis, lupus, and type I diabetes.
