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。

RESULTS:(1)NO production and iNOS mRNA expression induced by LPS and TNF α was blocked by pyrrolidine dithiocarbamate or N-acetylcysteine.(2)LPS and TNF α triggered the activation and translocation of NF κ B, and PDTC or NAC inhibited the activation of NF κ B induced by LPS and TNF α.

Taken together, our data showed that both the CSF-box and the octamer are important for the LPS-induced G-CSF promoter activity, moreover, the activation of MEK/ERK signaling pathway is indispensible for LPS-induced G-CSF expression in RAW264.7 macrophage.. It seems that LPS-induced activation of MEK/ERK pathway does not directly regulates NF-κB transactivity, but is essential for LPS-induced Oct-2 binding to the octmaer within G-CSF promoter and transcription activation of the G-CSF expression.

透过这些结果，我们认为MEK/ERK pathway的确参与LPS活化G-CSF表现的过程，虽然MEK/ERK pathway都影响了CSF-box以及octamer对G-CSF启动子所贡献的活性，但似乎MEK/ERK pathway的下游并非直接影响NF-κB调控基因转录的活性，而主要是影响了Oct-2对G-CSF启动子的调控。
