The cytoplasmic domain of CD28 is both necessary and sufficient for costimulation of interleukin-2 secretion and association with phosphatidylinositol 3'-kinase.
T-cell activation requires two signaling events. One is provided by the engagement of the T-cell antigen receptor, and the second represents a costimulatory signal provided by antigen-presenting cells. CD28 mediates a costimulatory signal by binding its ligands, B7-1 and B7-2, on antigen-presenting...
