CHO-K1/mouse TIGIT Stable Cell Line
TIGIT (also called T cell immunoreceptor with Ig and ITIM domains) is one newly discovered immune receptor on some percentage of T cells and Natural Killer Cells (NK). It is also identified as WUCAM and Vstm3. TIGIT binds to CD155 (PVR) on dendritic cells (DCs), macrophages, etc. with high affinity, and also to CD112 (PVRL2) with lower affinity. Research has shown that TIGIT-Fc fusion proteins interact with PVR on dendritic cells and increase IL-10 secretion, while decreasing IL-12 secretion under LPS stimulation. TIGIT-Fc fusion proteins also inhibit T cell activation in vivo. TIGIT's inhibition of NK cytotoxicity can be blocked by antibodies against its interaction with PVR, which is directed through its ITIM domain.
