Glucocorticoid-Induced TNFR-Related protein (GITR, TNFRSF18, AITR, CD357) is an immune checkpoint, cell surface receptor expressed on T-cells, and its expression increases when the T cells are activated. GITR binds GITRL (AITRL), a cytokine that is secreted by endothelial cells. Knockout studies in mice suggest that GITR helps regulate CD3-driven T-cell activation and programmed cell death. The soluble form of GITR is elevated in cancer.
