第一信号为抗原与T细胞受体TCR的结合，第二信号为抗原递呈细胞上的协同刺激分子与T、B淋巴细胞上的受体结合。
The first signal is the binding of antigen with TCR on T cells. The second signal is the binding of co-stimulate on the APC with their receptors presenting on T and B lymphocytes.
角膜移植手术失败的主要原因是T细胞介导的免疫排斥反应，T细胞的充分活化需要共刺激信号的协同作用。
The leading cause of corneal graft failure is T cell-mediated immune rejection. Costimula-tion has been shown to be necessary for full activation of naive T cell.
