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

仅有激，缺乏共激信号的T细胞不仅不活化，反而导无乃至凋亡。

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的胞膜表达,我们体内鉴别并分离无与活化的T细胞.
