4-1BB Receptor (CD137) is a member of the TNF receptor superfamily expressed on activated CD4 and CD8 T cells as well as on activated natural killer cells. The binding of 4-1BB to its TNF family ligand, 4-1BB ligand (4-1BBL) delivers a costimulatory signal to resting T cells leading to high level IL-2 production independently of CD28 signaling.
