T cells will become anergic or apoptotic , when there is antigen stimulation without costimulatory molecules.

仅有抗原刺激，缺乏共刺激信号T不仅不活化，反而导无能乃至凋亡。

Furthermore, by examining CD71 surface expression, we are able to distinguish and differentially isolate anergic and actiated T cells in io.

另外,测CD71膜表达,我们能够在体内鉴别并分离无能与活化T.
