Results: 1 Tritiated thymidine incorporation assay showed that 1μM adenosine plus coformycin slightly inhibited CTLL-2 proliferation, while 5-20μM adenosine elicited marked inhibition on CTLL-2 proliferation responded to IL-2 a dose-dependent fashion. 2 Coformycin alone could also inhibit CTLL-2 proliferation at the concentration of 2.5μM. The underlying reason maybe due to the endogenous adenosine produced by CTLL-2 cells.

结果：11μM腺苷对CTLL-2增殖仅有轻微的抑制作用，而5、10、20μM腺苷的存在可显著抑制CTLL-2的增殖，并且呈剂量相关，P值均小于0.05.2CTLL-2经过2.5μM助间型霉素的单独处理也可引起轻度的增殖受抑现象，分析其可能原因是T细胞自身可以分泌腺苷，所以该抑制现象的出现与内源性腺苷有关。3本实验所用腺苷浓度对CTLL-2的活细胞百分率影响轻微。
