Human TIGIT (Luc) Jurkat Reporter Cell Development Service

描述（Description）

The Human TIGIT (Luc) Jurkat Reporter Cell was engineered to not only express the NFAT response element driving luciferase expressing systems, but also express the receptor full length human TIGIT (Gene ID: 201633), which can use to evaluate the potency of TIGIT blockade. When co-cultured with target cells expressing human CD155, the TIGIT/CD155 interaction inhibits TCR signaling and NFAT-mediated luminescence. Blocking the TIGIT/CD155 interaction by either anti-TIGIT or anti-CD155 antibodies releases the inhibitory signal and results in TCR activation and NFAT-mediated luminescence.

背景（Background）

T cell immunoglobulin and ITIM domain (TIGIT) is an immune checkpoint that has been considered as a target in cancer immunotherapy and belongs to the family of poliovirus receptors (PVRs) that competes against CD226 (DNAM-1), which is the co-stimulatory receptor of T cells and NK cells, by binding to CD112 and CD155 (PVR) that are expressed on antigen-presenting cells (APCs) and various non-hematopoietic cell types, such as tumor cells. The TIGIT/PVR axis imparts a co-inhibitory effect on both T and NK cells that lead to their exhaustion, in turn triggering a negative signal that suppresses their activities, resulting in tumor-immune evasion.
