  5. Effective activation of antigen - specific t cells not only requires the first signal transduction through t - cell receptor ( tcr ) binding with peptide - mhc complex on the antigen presenting cell ( apc ), but also needs the second signal, termed costimulation. costimulation critical to the degree and consequence of t cell activation is provided by interaction between soluble factors or cell - surface molecules on the t cell and on the apc

    而t細胞的活化除需要t細胞受體（ tcr ）與抗原呈遞細胞（ antigenpresentingcell ， apc ）表面的抗原肽- mhc復合物結合所形成的第一信號外，還需要t細胞和apc表面的其它膜分子結合所提供的共刺激信號（亦稱第二信號或輔助刺激信號， costimulatorysignal ）的參與。
