Rheumatoid arthritis ( RA ) is one of the main diseases that result in loss of China's labor and disability, the prevention and control of this disease has very important significance. It has been confirmed that the activation of NF-κ B signal transduction pathway plays a crucial role in the development of RA. Inhibition of NF- κB signal transduction pathway can effectively inhibit proinflammatory cytokine gene expression, can induce apoptosis of synovial cells, can relieve the inflammatory immune response. NF-κB signal negative feedback regulation pathway mediated by A20 plays an important role in the inhibition of NF-κ B signal pathway. This project uses the animal model of RA ( AA rats ) as subjects, using electroacupuncture treatment, using morphological detection, radioimmunoassay, immunohistochemistry, RT-PCR, Western-blot and other technical means of detection, Through the the detection of synovial tissue inflammatory cytokine, A20、RIP1、c-IAP1、c-IAP2、IκB in synovial cell cytoplasm, NF-κB、A20mRNA in synovial cell core and cell factor mRNA, to study whether electro-acupuncture therapy inhibit NF- κB signal transduction pathway by activating the NF-κB signal negative feedback regulation pathway mediated by A20. So to explore the immune regulation mechanism of electroacupuncture treatment on RA.
类风湿性关节炎(RA)是造成我国人群丧失劳动力和致残的主要疾病之一。目前已证实NF-κB信号传导通路的激活对RA病情的发展起关键作用。抑制NF-κB信号通路可有效抑制促炎因子的基因表达,诱导滑膜细胞凋亡,缓解免疫炎症反应。A20主导的NF-κB信号通路负反馈调控途径在抑制NF-κB信号通路方面起重要作用。本项目以RA动物模型(AA大鼠)为受试对象,采用电针治疗,运用光镜、放免、免疫组化、RT-PCR、Western-blot等检测手段,通过对滑膜组织炎性细胞因子;滑膜细胞胞浆内A20、RIP1、c-IAP1、c-IAP2,IκB磷酸化;核内NF-κB、A20mRNA、细胞因子等mRNA的检测,研究电针是否通过启动A20主导的NF-κB信号通路负反馈调控途径抑制NF-κB信号通路的活化,探讨电针治疗RA的抗炎机制。
项目的背景:类风湿性关节炎(RA)是造成我国人群丧失劳动力和致残的主要疾病之一。目前已证实NF-κB信号传导通路的激活对RA病情的发展起重要作用。抑制NF-κB信号通路可有效抑制促炎因子的基因表达,诱导滑膜细胞凋亡,缓解免疫炎症反应。A20是NF-κB信号通路负反馈调控途径一个关键分子,在抑制NF-κB信号通路方面起重要作用。主要研究内容:本项目以RA动物模型(AA大鼠)为受试对象,采用电针治疗,运用光镜、放免、免疫组化、RT-PCR、Western-blot等检测手段,通过对滑膜组织炎性细胞因子;滑膜细胞胞浆内A20、RIP1、c-IAP1、c-IAP2,IκB磷酸化;核内NF-κB、A20mRNA、细胞因子等mRNA的检测,研究电针是否通过启动A20主导的NF-κB信号通路负反馈调控途径抑制NF-κB信号通路的活化,探讨电针治疗RA的抗炎机制。重要结果:①电针在减缓RA关节炎症和改善关节肿胀方面确有疗效;②证实了NF-κB信号传导通路对RA病情的发展起重要作用;③电针可以通过调节NF-κB信号传导通路对改善RA病情;④A20可能是电针通过调节NF-κB信号传导通路潜在作用因素。关键数据:①关节肿胀度,电针治疗组与模型组比较有显著性差异(P<0.01);②IκB磷酸化水平,电针治疗组与模型组比较有显著性差异(P<0.01);③胞浆内A20水平,电针治疗组与模型组比较有显著性差异(P<0.01)。科学意义:以“扶正祛邪”作为针灸治疗RA的整体思路,从分子生物学层面初步证实电针治疗RA的生物学机制,为RA发病机制与防治思路的研究提供新的策略。
