变应性鼻炎小鼠鼻黏膜lL-25、lL-33 mRNA表达水平的研究

目的：探讨IL-25 mRNA及IL-33 mRNA在变应性鼻炎小鼠鼻黏膜中的表达及其作用。方法利用Balb/c小鼠建立卵清蛋白致敏的变应性鼻炎小鼠模型，同时使用生理盐水作为对照组，取各组小鼠鼻黏膜组织，使用实时定量PCR法检测两组小鼠鼻黏膜中IL-25 mRNA和IL-33 mRNA的含量。结果IL-25 mRNA和IL-33 mRNA在对照组以及实验组中均有表达，且实验组明显高于对照组，两组比较差异具有统计学意义（P＜0.05）。结论 IL-25和IL-33参与到变应性鼻炎的发病机制中，该结果将有助于提高对变应性鼻炎发病机制的进一步了解，为变应性鼻炎潜在的靶向药物治疗提供了理论依据。

Expression level of IL-25 and IL-33 mRNA in nasal mucosa of allergic rhinitis mice

[ABSTRACT]OBJECTIVETo investigate the expression levels of IL-25 and IL-33 mRNA in the nasal mucosa of allergic rhinitis(AR) mice.METHODSBalb/c mice were used for establishing the animal model of allergic rhinitis with oval bumin sensitization as AR group, at the same time, the physiological saline as the control group. IL-25 and IL-33 mRNA in nasal mucosa of the two groups were detected by real-time quantitative PCR.RESULTSThe expression of IL-25 and IL-33 mRNA could be detected in both the control and AR group. The expression level of IL-25 and IL-33 mRNA in AR group were significantly higher than that in control group, the difference was statistically significant (P<0.05).CONCLUSIONIL-25 and IL-33 were involved in the development of allergic rhinitis. This result will be helpful for the further understanding of the pathogenesis of allergic rhinitis, and provide a theoretical basis for the treatment of allergic rhinitis.
