B7-H3 acts through T cell costimulation and coinhibition and beyond. Phylogenetic tree of the B7 family generated by PAUP (2, 3). This analysis divides the B7 family into three groups. B7-H3 is broadly expressed. It binds to TLT-2 and costimulates T cell activation, whereas binding to unidentified receptor(s) leads to coinhibition of T cells. In addition, B7-H3 is an inhibitor for NK cells and osteoblastic cells by ligating unknown receptor(s).
