TIGIT: An emerging immune checkpoint target for …
网页2023年7月1日 · TIGIT binds CD155 with higher affinity than CD226, results in the distruption of CD226 homodimerization and impediment of CD226-mediated T cells activation. Activation of TIGIT signaling in Treg enhances its stability and suppression via IL-10 and Fg12 secretion, lead to the inhibition of Thl and Th17.
CD226: An Emerging Role in Immunologic Diseases - PMC
网页2020年7月24日 · TIGIT and CD226 costimulatory axis plays an important role in the immunoregulatory function of Foxp3 + Tregs and is related to several autoimmune diseases. Several lines of evidence support that the suppressive capacity of CD226 + Tregs is inhibited (Ning et al., 2019), and that TIGIT + Tregs are highly suppressive and more so (Joller et al., 2014
