Background
B7-DC [also known as programmed death ligand 2 (PD-L2)] is a costimulatory molecule expressed predominantly on dendritic cells (DCs) and macrophages. In addition to its coinhibitory receptor, programmed death receptor 1 (PD-1), evidence suggests that B7-DC interacts with an unidentified costimulatory receptor on T cells. B7-DC mutants with selective binding capacity for the costimulatory receptor may be effective in stimulating antitumor immune responses, while avoiding the inhibitory effects of PD-1.
