AITRL, a type II transmembrane protein, is a ligand for glucocorticoid-induced TNFR-related protein (GITR) . When AITRL binds to GITR, GITR can produce costimulatory signals that regulate T-cell proliferation and effector functions. GITR/AITRL interaction plays a role in the pathogenesis of tumor, inflammation, as well as autoimmune diseases[1]. Besides, AITRL plays a role in endothelial cells (EC) -activation and increases STAT-1 phosphorylation and the expression of adhesion molecules (VCAM-1, ICAM-1) [2]. AITRL/TNFSF18 Protein, Mouse is a recombinant mouse AITRL (T47-S173) without tag, which is expressed in E.coli.
