TIGIT Specific Neutra^TM Antibody Products

Product list

T cell immunoreceptor with Ig and ITIM domains (TIGIT), also known as VSIG9, is a protein expressed in peripheral blood mononuclear cells and involved in T cell apoptosis. TIGIT interacts with ligands such as CD155 and CD112 expressed by antigen-presenting cells (APCs) and tumor cells in the tumor microenvironment (TME). The inhibitors against TIGIT can attack tumors by blocking interaction with TIGIT via activation of the immune system.

Its Gene ID is 201633, UniProtKB ID is Q495A1, and OMIM ID is 612859.

Signaling Pathway & Function

As an inhibitor, TIGIT mediates strong inhibitory signaling pathways for innate and adaptive immunity, as shown in Fig.1. Here are five main inhibitory mechanisms associated with TIGIT in TEM:

Inhibits T cell function by direct binding of CD155 on DCs with intrinsic inhibitory effect.
Binds CD155 on APCs and inhibits T cells indirectly by regulating cytotoxin production.
Binds CD155 on tumor cells or APCs and inhibits CD226-mediated T/NK cell activation.
Enhances the immunosuppressive function and stability of regulatory T cells (Tregs).
Binds Fap2 protein of Fusobacterium nucleatum and triggers inhibitory signals for T/NK cells.

Clinical Significance of TIGIT

Anti-TIGIT antibodies have become hotspots for immunotherapy. More than a dozen TIGIT antibodies are currently being developed in various stages of clinical and preclinical research (see Table 1).

The development of bispecific antibodies targeting TIGIT and another immune checkpoint protein such as PD-L1 is also in development. These bispecific antibodies could augment the therapeutic efficacy against tumors due to their high specificity and affinity for both targets, including TIGIT.
