Description	Recombinant Jurkat T cell expressing firefly luciferase gene under the control of NFAT response elements with constitutive expression of human CD160. CD160 is a GPIanchored glycoprotein member of the Ig superfamily, also known as BY55, NK1, and NK28. GenBank Accession # NM_007053. Mycoplasma testing: The cell line has been screened using the PCR-based VenorGeM Mycoplasma Detection kit (Sigma-Aldrich, #MP0025) to confirm the absence of Mycoplasma species. Host Species: human Supplied as Each vial contains 2 x 10^6 cells in 1 ml of 10% DMSO
Background	CD160 is a glycosylphosphatidylinositol (GPI)-anchored protein member of the Ig superfamily that is expressed at the cell surface and highly restricted to circulating NK and T cells. Binding of CD160 to both classical and non-classical MHC I enhances NK and CD8+ CTL functions. However, engagement of CD160 by the Herpes Virus Entry Mediator (HVEM / TNFRSF14) was shown to mediate inhibition of CD4+ T-cell proliferation and TCR-mediated signaling. HVEM protein is a bimolecular switch that binds both co-stimulatory LT-alpha/LIGHT and co-inhibitory receptors CD160/BTLA. The binding of coinhibitory receptors CD160 and/or BTLA on T cells with HVEM expressed on DC or Tregs transduces negative signals into T cells that are counterbalanced by costimulatory signals delivered after direct engagement of HVEM on T cells by LIGHT expressed on DC or more likely, on other activated T cells (T-T cell cooperation).HVEM was also shown to be expressed in the majority of cultured melanoma cell lines and metastatic melanoma samples. The predominance of the interaction of HVEM with CD160 and BTLA over the HVEM/LIGHT pathway or vice versa might be the result of differences in ligand/receptor affinity and the differential expression pattern of these molecules on cell types at different stages of cell differentiation. LIGHT, BTLA, and CD160 have substantially different binding affinities and occupy spatially distinct sites upon interaction with the HVEM receptor, which enables HVEM to function as a molecular switch.The net effect of the LIGHT/HVEM and HVEM/BTLA/CD160 interaction, when these different receptors and ligands are simultaneously present, determines the outcome of the response. CD160/HVEM interaction plays a key role in the regulation of inflammatory, autoimmune, and antitumor responses, and is an important target for cancer immunotherapy drug discovery. The interaction of CD160 on tumor specific T cells and HVEM on melanoma cells resulted in T cell inhibition, which could be reversed by treatment with anti-CD160 blocking antibody. Therapeutically targeting CD160 and HVEM remains a focus for in pre-clinical studies as the bidirectional signaling pathways of CD160/BTLA/HVEM and HVEM/LIGHT are further elucidated.
