To investigate the expression of interleukin (IL)-23 in the nasal mucosa of allergic rhinitis patients and its significance.
mRNA and protein expression of IL-23 in inferior turbinate mucosa from 12 allergic rhinitis patients and 11 control patients was measured by means of real-time RT-PCR and immunohistochemistry, respectively.
IL-23p19 mRNA relative expression level in nasal mucosa was significantly increased in allergic rhinitis patients compared with normal controls (P < 0.01). Immunohistochemical staining demonstrated that IL-23 protein was mainly expressed by infiltrating inflammatory cells in lamina propria and there was increased number of IL-23 positive cells in allergic rhinitis patients in comparison with normal controls. Correlation analysis showed that the mRNA and protein expression level of IL-23 was significantly positively correlated with the number of the inflammatory cells (r = 0.678 and 0.644, respectively; both P < 0.01) and the degree of subepithelial collagen deposition (r = 0.834 and 0.721, respectively; both P < 0.01). IL-23p19 mRNA relative expression level in nasal mucosa was significantly decreased in allergic rhinitis patients who used glucocorticoids compared with controls (P < 0.01).
IL-23 may contribute to the chronic inflammation and airway remodelling in allergic rhinitis.
探讨白细胞介素(IL)-23在变应性鼻炎患者鼻黏膜中的表达及其意义。
分别采用实时逆转录聚合酶链反应(RT-PCR)和免疫组织化学方法检测12例变应性鼻炎患者及11例对照患者下鼻甲黏膜中IL-23的mRNA和蛋白表达。
与正常对照组相比,变应性鼻炎患者鼻黏膜中IL-23p19 mRNA相对表达水平显著升高(P < 0.01)。免疫组织化学染色显示,IL-23蛋白主要由固有层浸润的炎性细胞表达,与正常对照组相比,变应性鼻炎患者中IL-23阳性细胞数量增加。相关性分析表明,IL-23的mRNA和蛋白表达水平与炎性细胞数量(分别为r = 0.678和0.644;均P < 0.01)及上皮下胶原沉积程度(分别为r = 0.834和0.721;均P < 0.01)呈显著正相关。与对照组相比,使用糖皮质激素的变应性鼻炎患者鼻黏膜中IL-23p19 mRNA相对表达水平显著降低(P < 0.01)。
IL-23可能参与变应性鼻炎的慢性炎症和气道重塑过程。
