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

仅有抗原，缺乏信号的T细不仅不活化，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,通过检测CD71的达,我们能够在体内鉴别并分离无能与活化的T细.
