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.
在过去几年中，共刺激分子在调节T细胞反应中的关键作用已得到证实。共刺激分子CD28增强T细胞反应，而CTLA-4则下调T细胞反应。在细胞和分子水平上对共刺激分子和T细胞受体介导的信号整合的理解才刚刚开始。
