Background	T-lymphocyte activation antigen CD80 (B7-1) is a ~33 kDa protein. Costimulatory molecule that belongs to the immunoglobulin superfamily that plays an important role in T-lymphocyte activation. Acts as the primary auxiliary signal augmenting the MHC/TCR signal in naive T-cells by acting as a ligand for the CD28 receptor which is constitutively expressed on the cell surface of T-cells. In turn, activates different signaling pathways such as NF-kappa-B or MAPK leading to the production of different cytokines. Also acts as an inhibitor of T-cell activation by acting as a ligand for CTLA4, a decoy receptor, thereby blocking CD28-mediated T-cell priming. In addition, CD28/CD80 costimulatory signal stimulates glucose metabolism and ATP synthesis of T-cells by activating the PI3K/Akt signaling pathway. 1. Lu, B. et al.
