目的:探讨细胞因子GM-CSF、IL-8、TNF-α在哮喘发病中的作用及雷公藤对细胞因子产生的影响。方法:以卵蛋白雾化吸入诱导哮喘豚鼠实验模型,用雷公藤处理,斑点印迹杂交检测支气管肺组织GM-CSFmRNA表达,ELISA测定血浆中IL-8、TNF-α含量。结果:哮喘组豚鼠肺组织GM-CSFmRNA表达和血浆中TNF-α水平明显增高,但血浆中IL-8升高不明显。雷公藤处理后GM-CSFmRNA表达及TNF-α水平降低。结论:GM-CSF等细胞因子产生增加,可能是导致哮喘气道炎症的原因。雷公藤能抑制细胞因子的产生,可能在哮喘患者抗炎治疗中有潜在的应用价值
Objective: To investigate the role of cytokines GM-CSF, IL-8 and TNF-α in the pathogenesis of asthma and the effect of triptolide on cytokine production. Methods: Asthmatic guinea pigs were induced by nebulized ovalbumin, and the expression of GM-CSF mRNA in bronchial lung tissue was detected by tripterygium wilfordii and dot blot hybridization. The levels of IL-8 and TNF-α in plasma were measured by ELISA. Results: The expression of GM-CSF mRNA and the level of TNF-α in plasma of asthmatic guinea pigs were significantly increased, but the levels of IL-8 in plasma were not significantly increased. After treatment of Tripterygium wilfordii, GM-CSF mRNA expression and TNF-α level decreased. Conclusion: Increased production of cytokines such as GM-CSF may be the reason of airway inflammation in asthma. Tripterygium can inhibit the production of cytokines, which may have potential value in anti-inflammatory treatment of asthma patients
