A human monoclonal antibody targeting the co-inhibitory molecule and immune checkpoint inhibitor T-cell immunoreceptor with immunoglobulin (Ig) and immunoreceptor tyrosine-based inhibitory motif (ITIM) domains (TIGIT), with potential immune checkpoint inhibitory activity. Upon administration, anti-TIGIT monoclonal antibody BMS-986207 binds to TIGIT expressed on various immune cells, particularly on tumor-infiltrating T lymphocytes (TILs), thereby preventing the interaction of TIGIT with its ligands CD112 (nectin-2; poliovirus receptor related-2; PVRL2) and CD155 (poliovirus receptor; PVR; nectin-like protein 5; NECL-5). This enhances the interaction of CD112 and CD155 with the costimulatory receptor CD226 (DNAX Accessory molecule-1; DNAM-1), which is expressed on immune cells, such as natural killer (NK) cells and CD8+ T cells, and leads to CD226 dimerization and CD226-mediated signaling. This activates the immune system to exert a T-cell-mediated immune response against cancer cells. TIGIT, a member of the Ig super family and an immune inhibitory receptor, plays a key role in the suppression of T-cell proliferation and activation; it is involved in tumor cell immune evasion, and the inhibition of antiviral immune responses.
