Treatment with CpG-ODN inhibited the expression of Fas in Jurkat cells. Jurkat cells were treated with 1 μM CpG-ODN for 24 h, and the cells were collected. The intracellular expression of Fas was examined by qRT-PCR (A) and FCM (B). Data are expressed as mean% ± SEM of each group of the cells from four separate experiments. *p < 0.05 vs. the controls.
