摘要: 目的: 探讨补体C5a受体拮抗剂PMX205的体外抗炎作用。方法: MTT法检测PMX205对小鼠巨噬细胞(RAW264.7)的毒性。RAW264.7与牙龈蛋白酶(gingipain,G)体外共培养模拟炎症环境,观察PMX205的抗炎效果。实验分为6组:阴性对照组、G组、G+PMX205(0.1、1、5、10 mg/L)组,24 h后qRT-PCR、ELISA法检测M1型巨噬细胞标志性细胞因子IL-6及TNF-α,M2型标志性细胞因子IL-10和TGF-β1;流式细胞术检测M1型标志性分子CD86及M2型标志性分子CD206。结果: MTT结果显示,PMX205对RAW264.7活力影响较小。qRT-PCR及ELISA结果显示,G组IL-6和TNF-α表达水平较阴性对照组增加;G+PMX205各浓度组的IL-6和TNF-α的表达水平较G组减少,TGF-β1和IL-10表达水平均较G组增加(P<0.01或P<0.05)。流式细胞术结果显示,G组CD86阳性率增加,CD206阳性率下降,G+PMX205组较G组CD86下降,而CD206增加。结论: 在体外细胞模型实验中PMX205具有良好的抗炎作用。

Abstract: Objective: To explore the anti-inflammatory effects of C5aR antagonist PMX205. Methods: The toxicity of PMX205 for the mouse macrophage (RAW264.7) was tested with MTT assay. RAW264.7 cells were co-cultured with gingipains (G) to simulate the inflammatory environment in vitro and the anti-inflammatory effects of PMX205 was observed. The experiment was divided into six groups: negative control group, G group, and G + PMX205(0.1,1,5,10 mg/L)group. After cultured for 24 h, qRT-PCR and ELISA were used to detect IL-6, TNF-α, IL-10 and TGF-β1. Flow cytometry was used to detect the M1 marker molecule CD86 and M2 marker molecule CD206. Results: MTT results showed that PMX205 had little effect on the viability of RAW264.7. qRT-PCR and ELISA results showed that IL-6 and TNF-α expression levels of G group were higher than the negative control group. The expression of IL-6 and TNF-α were decreased in G + PMX205 group, and TGF-β1 and IL-10 were higher than those in G group. Flow cytometry showed that CD86 positive rate was increased and the CD206 positive rate was decreased in G group. In G+PMX205 group the CD86 was decreased, the CD206 was higher than those in G group. Conclusion: In vitro cell model experiments, PMX205 showed good anti-inflammatory effects
