Background: CD28

CD28 and CTLA-4, together with their ligands, B7-1 and B7-2, constitute one of the dominant costimulatory pathways that regulate T and B cell responses. CD28 and CTLA-4 are structurally homologous molecules that are members of the immunoglobulin (Ig) gene superfamily. Mouse CD28 is expressed constitutively on virtually 100% of mouse T cells and on developing thymocytes.
