Gene Description:

TNFRSF18 (TNF Receptor Superfamily Member 18) is also known as Glucocorticoid-induced TNFR-related protein (GITR), which is expressed on many immune cells including T cells. As a co-stimulatory signal of T cells, TNFRSF18 is up-regulated upon the activation of T cells, and in turn promotes T cell proliferation. CD25+/CD4+ regulatory T cell is known to mediate immune tolerance, and GITR agonist antibodies can reverse this immune tolerance, and show anti-tumor effect in multiple tumor models.
