title: Costimulatory regulation of T cell function.
abstract: During the past several years, the critical role of costimulatory molecules in regulating T cell responses has been demonstrated. Costimulatory molecule CD28 enhances whereas CTLA-4 downmodulates T cell responses. An understanding of the integration of the signals mediated by costimulatory molecules and the T cell receptor at the cellular and molecular levels is just beginning to be achieved.
