摘要
目的探讨变应性鼻炎患者鼻黏膜中白介素(interleukin,IL)-17A及黏蛋白MUC5AC的表达及相互关系。方法总共纳入14例中-重度持续性变应性鼻炎患者和9例正常对照者,采用定量逆转录聚合酶链反应(qRT-PCR)和免疫组化检测下鼻甲黏膜中IL-17A和MUC5AC的mRNA及蛋白表达情况,评估两者之间的关联性。结果变应性鼻炎患者鼻黏膜中IL-17A和MUC5AC mRNA表达分别比对照组织上升3.7倍和8.9倍,差异有统计学意义(P<0.01),两者的蛋白表达强度也显著高于正常对照组(P<0.05)。而且IL-17A和MUC5AC的mRNA与蛋白表达之间存在显著正相关(r=0.79和r=0.85,P<0.05)。结论 IL-17A可能通过刺激MUC5AC的表达加重变应性鼻炎的临床严重度并且影响其疗效。
Objective To examine the expression of interleukin(IL)-17A and MUCSAC and evaluate the relationship in patients with allergic rhinitis (AR). Method Fourteen patients with moderate to severe AR and 9 normal controls were enrolled. IL-17A and MUC5AC mRNA in nasal mucosa were determined by quantitative reverse transcription polymerase chain reaction (qRT-PCR), and the protein was located by immunohistochemistry (IHC). Results We found that IL-17A and MUCSAC mRNA expression were elevated for 3.9 and 7.9 folds, respectively, with significant difference (P〈0.01). And IL-17A and MUC5AC protein expression were also found to be increased in AR patients when compared with the normal controls (P〈0.05). And IL-17A level (mRNA and protein) was found to be positively associated with MUCSAC level (mRNA and protein) (r=0.79 and r=0.85, P〈0.05). Conclusion The expression of IL-17A is associated with MUC5AC level in patients with AR, which might play important role in enhancing clinical severity of AR and affecting clinical efficacy of intranasal corticosteroid.
