1 We developed an IgG4-type monoclonal antibody against human TIGIT, designated as MG1131, using a phage display library of single-chain variable fragments (scFvs). mg1131 T cell immunoreceptor with Ig and ITIM domains Homo sapiens
2 MG1131 interacts with TIGIT much more tightly than PVR does. mg1131 T cell immunoreceptor with Ig and ITIM domains Homo sapiens
3 The crystal structure of a scFv version of MG1131 bound to TIGIT was determined, showing that MG1131 could block the PVR-TIGIT interaction and thus the immunosuppressive signaling of TIGIT. mg1131 T cell immunoreceptor with Ig and ITIM domains Homo sapiens
4 The crystal structure of a scFv version of MG1131 bound to TIGIT was determined, showing that MG1131 could block the PVR-TIGIT interaction and thus the immunosuppressive signaling of TIGIT. mg1131 T cell immunoreceptor with Ig and ITIM domains Homo sapiens
5 The crystal structure of a scFv version of MG1131 bound to TIGIT was determined, showing that MG1131 could block the PVR-TIGIT interaction and thus the immunosuppressive signaling of TIGIT. mg1131 T cell immunoreceptor with Ig and ITIM domains Homo sapiens
6 The crystal structure of a scFv version of MG1131 bound to TIGIT was determined, showing that MG1131 could block the PVR-TIGIT interaction and thus the immunosuppressive signaling of TIGIT. mg1131 T cell immunoreceptor with Ig and ITIM domains Homo sapiens
7 The crystal structure of a scFv version of MG1131 bound to TIGIT was determined, showing that MG1131 could block the PVR-TIGIT interaction and thus the immunosuppressive signaling of TIGIT. mg1131 T cell immunoreceptor with Ig and ITIM domains Homo sapiens
8 The crystal structure of a scFv version of MG1131 bound to TIGIT was determined, showing that MG1131 could block the PVR-TIGIT interaction and thus the immunosuppressive signaling of TIGIT. mg1131 T cell immunoreceptor with Ig and ITIM domains Homo sapiens
9 Consistently, MG1131 is bound to TIGIT-expressing cells and interferes with PVR binding to these cells. mg1131 T cell immunoreceptor with Ig and ITIM domains Homo sapiens
