Fig. 7: Anti-human-TIGIT agonistic mAb (αTIGIT) regulates T cell imbalance in autoimmune states.

a TIGIT expression is upregulated by T cell stimulation, especially in Tfh and Treg cells. αTIGIT selectively and strongly suppressed Tfh cells and promoted the suppressive function of Treg cells. b αTIGIT can recover imbalance towards activated T cells by conflicting effects on CD4+ T cells.
