摘要:

目的 探讨过敏原对健康人(healthy control,HC)和过敏性鼻炎(allergic rhinitis,AR)患者外周血CD4+ Th1细胞表达IL-18、IL-18BPa和IL-18Rα蛋白水平及mRNA水平的影响。 方法 收集皮肤点刺试验阴性的鼻炎(AR-)、皮肤点刺试验阳性的鼻炎(AR+)患者和HC的外周血标本。流式细胞术检测过敏原对CD4+ Th1细胞表达IL-18、IL-18BPa和IL-18Rα蛋白水平的影响;qPCR检测过敏原对CD4+ T细胞表达IL-18、IL-18BPa和IL-18Rα mRNA水平的影响。 结果 与HC相比,AR-和AR+患者外周血Th1细胞中IL-18蛋白的表达增加,IL-18BPa蛋白的表达减少;AR+患者外周血Th1细胞中IL-18Rα蛋白的表达增加;过敏原可增强HC Th1细胞IL-18Rα蛋白的表达,并诱导AR+患者和HC CD4+ T细胞IL-18、IL-18BPa和IL-18Rα mRNA的表达。 结论 过敏原极可能通过促进外周血CD4+ Th1细胞表达IL-18和IL-18Rα进而参与AR发病。

Abstract:

Objective To investigate the effects of allergens on the expressions of IL-18, IL-18BPa and IL-18Rα protein in peripheral blood CD4+ Th1 cells of healthy control subjects (HC) and patients with allergic rhinitis (AR), and on the expressions of IL-18, IL-18BPa and IL-18Rα mRNA in the peripheral blood CD4+ T cells. Methods Blood samples were collected from patients with rhinitis for negative skin prick test (AR-), rhinitis for positive skin prick test (AR+) and HC. Flow cytometry was used to evaluate the effects of allergens on the expressions of IL-18, IL-18BPa and IL-18Rα protein in CD4+ Th1 cells. The expressions of IL-18, IL-18BPa and IL-18Rα mRNA in CD4+ T cells were determined by qPCR. Results Compared with HC, increased IL-18 while decreased IL-18BPa expressions in Th1 cells of AR- and AR+ patients were observed, increased IL-18Rα expression in Th1 cells of AR+ patients was also found. Additionally, allergens induced elevated expression of IL-18Rα protein in Th1 cells of HC, and induced elevated mRNA expressions of IL-18, IL-18BPa and IL-18Rα in isolated blood CD4+ T cells of AR+ patients and HC. Conclusion Allergens may be involved in the pathogenesis of AR by inducing the expressions of IL-18 and IL-18Rα in blood CD4+ Th1 cells.
