title: T cells: A proliferation of costimulatory molecules.
abstract: The identification and characterization of a newly extended family of molecules related to the T-cell costimulatory proteins CD28 and B7 suggests that a distinct form of costimulatory signals could be important for effector T-cell responses outside of lymphoid tissues.
