基于PK—PD模型研究雷公藤治疗类风湿关节炎生物靶标(1)
[摘要]运用PK-PD模型观察血清样本及雷公藤治疗类风湿关节炎(RA)的抗炎作用,并分别对浓度-时间、效应-时间曲线进行相关分析,采用PCR检测各组大鼠的RORγt,IL-17,STAT3,IL-6mRNA转录水平。甲氨蝶呤、雷公藤红素和高剂量的雷公藤,均可下调AA大鼠淋巴结中RORγt,IL-17,STAT3,IL-6mRNA转录水平。根据PK-PD模型研究表明炎症因子与雷公藤的血药浓度存在一定的相关性。雷公藤及其主要活性成分雷公藤红素可通过抑制IL-17细胞因子实现抗炎作用来治疗RA。

[Abstract]To observe the serum samples and the anti-inflammatory effect of Tripterygium wilfordii in treating RA by using the pharmacokinetic-pharmacodynamic model, make a correlation analysis on concentration-time and effect-time curves, and explore RORγt, IL-17, STAT3, IL-6 mRNA transcriptional levels in rats by PCR. Methotrexate, tripterine and high-dose T. wilfordii could down-regulate RORγt, IL-17, STAT3, IL-6 mRNA transcriptional levels in AA rat lymph nodes. The study on PK-PD model showed correlations between inflammatory factors and blood concentration of T. wilfordii. T. wilfordii and its main active constituent tripterine could show the inflammatory effect and treat RA by inhibiting IL-17 cytokine.

中药在类风湿关节炎(RA)治疗方面具有独特的优势。近年来国内外学者已从中药和天然药物中筛选出了多种抗RA的有效成分,并开发了诸多中药制剂[1-3]。雷公藤临床疗效显著,而对其是否能治疗RA的药理作用研究及其可能机制则报道较少。基于此,本研究观察雷公藤对佐剂性关节炎(adjuvant-inducedarthritis,AA)大鼠的抗炎作用,并通过雷公藤对IL-17等的影响探讨其部分作用机制,考察雷公藤对RA的潜在治疗作用[4]。
目前,雷公藤活性成分对Th17细胞作用研究主要以雷公藤甲素为主。研究发现雷公藤主要活性成分对Th17细胞及其相应的信号通路有明显的抑制作用。雷公藤甲素可以抑制IL-17产生从而保护大鼠缺血再灌注损伤,也可以改善骨髓移植小鼠模型的肺炎综合征症状[6-7]。近期研究表明,雷公藤甲素可以抑制CD4+T细胞分化成Th17细胞以及抑制IL-6/STAT3信号通路从而减少IL-17的产生[8-9],从而抑制胶原诱导的关节炎[10]。, 百拇医药(刘史佳 戴国梁 孙冰婷 李长印 吴磊 马世堂 居文政 谈恒山 傅海燕)
