RESULTS: Both resting B cells and T cells did not express PD-L1 on their surface, however PD-L1 expression was significantly up-regulated on the surface of the activated B cells after 6 h stimulation with LPS or pokeweed mitogen, and the percentages of B cells that expressed PD-L1 reached a plateau at 24 h, which were (46.26±10.71)% with LPS and (43.67±6.14)% with PWM stimulation, respectively. No markedly change of PD-L1 expression on the surface of the activated T cells after stimulation with LPS was observed, but upregulation of PD-L1 expression was observed when stimulation with PWM.

结果： 静息B细胞和T细胞表面不表达PD-L1，LPS和PWM刺激6 h后表达PD-L1的B细胞百分率均显著高于静息B细胞，24 h达到最高，分别为(46.26±10.71)%和(43.67±6.14)%，之后随时间延长而降低；表达PD-L1的T细胞百分率在LPS刺激下无显著变化，但PWM刺激6 h后百分率明显高于静息条件，24 h达到最高，为(25.42±9.23)%，之后下降。
