26842126 implying that TIGIT exerts immunosuppressive effects by competing with DNAM-1 for the same ligand, CD155
26741490 These findings identify TIGIT as a novel marker of dysfunctional HIV-specific T cells
26735971 This study shows that HBZ-induced TIGIT plays a pivotal role in attenuating host immune responses and shaping a microenvironment favorable to human T-cell leukemia virus type 1.
26250578 TIGIT-positive circulating follicular helper T cells display robust B-cell help functions: potential role in sickle cell alloimmunization.
26171588 a novel mechanism that links TIGIT expression with NK-cell functional heterogeneity, and this mechanism might partially explain why individuals have different susceptibilities to infection, autoimmune disease, and cancer.
25994968 Human regulatory T cells expressing the receptors TIGIT and CD226 display widely divergent phenotypes in regard to expansion and activation.
25866972 TIGIT and PD-1 blockade additively increased proliferation, cytokine production, and degranulation of tumor-antigen-specific CD8 T cells and CD8 TILs. TIGIT and PD-1 regulate the expansion and function of these T cells in melanoma.
25762785 the TIGIT/FCRL3 combination allows reliable identification of Helios(+) Treg cells even in highly activated conditions in vitro as well as in PBMCs of autoimmune patients.
25680274 The results identify a bacterium-dependent, tumor-immune evasion mechanism in which tumors exploit the Fap2 protein of F. nucleatum to inhibit immune cell activity via TIGIT.
25465800 Findings suggest that TIGIT is a key checkpoint inhibitor of chronic antiviral and antitumor responses through impairing CD226 function when disrupting its homodimerization.
24817116 TIGIT/PVR ligation signaling mediates suppression of IFN-gamma production via the NF-kappaB pathway.
23154388 TIGIT is phosphorylated at its cytoplasmic tail after its ligation with PVR.
22706088 The Tim-3 pathway appears to control regulatory (Treg) and effector T cell balance via altering cell proliferation and apoptosis during hepatitis C virus infection.
22427644 TIGIT can inhibit T cell functions by competing with CD226 and can also directly inhibit T cells in a T cell-intrinsic manner.
22421438 data suggest a cis-trans receptor clustering mechanism for cell adhesion and signaling by the TIGIT/PVR complex and provide structural insights into how the PVR family of immunoregulators function
21416464 that soluble Vstm3 attenuates T-cell responses in vitro and in vivo
19815499 TIGIT counter inhibits the NK-mediated killing of tumor cells and protects normal cells from NK-mediated cytotoxicity thus providing an "alternative self" mechanism for MHC class I inhibition.
19197944 a novel immunoreceptor, Washington University Cell Adhesion Molecule, which is expressed on human follicular B helper T cells, was described.
19011627 TIGIT exerts immunosuppressive effects by binding to poliovirus receptor and modulating cytokine production by dendritic cells.
