Recombinant Jurkat T cell expressing firefly luciferase gene under the control of NFAT response elements with constitutive expression of human PD-1 (Programmed Cell Death 1, PDCD1, SLEB2, CD279, GenBank Accession #NM_005018).
Mycoplasma testing: The cell line has been screened using the PCR-based VenorGeM Mycoplasma Detection kit (Sigma-Aldrich) to confirm the absence of Mycoplasma species.
Host Species: human
Supplied as Each vial contains 2 X 106 cells in 1 ml of 10% DMSO
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.
Application
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
