A549细胞中Fas、FasL以及Caspase-8蛋白的表达（Mean±SD）

Protein expressions of Fas, FasL and Caspase-8 in A549 cells (Mean±SD)

Group	Control (A549 group)	A549/Jurkat=50:1	A549/Jurkat=20:1	A549/Jurkat=10:1	A549/Jurkat=1:1
*: P < 0.05, ***: P > 0.05, compared among experimental groups; **: P > 0.05, compared with the control group. Experimental groups were 50:1, 20:1, 10:1, 1:1 (A549/Jurkat); the control group was only A549 cells.
