摘要: 目的:探讨寻常型银屑病患者血清中白细胞介素17(IL-17)的表达水平及IL-17刺激后HaCaT细胞分泌白细胞介素6(IL-6)和白细胞介素23(IL-23)的变化,阐明其临床意义及紫草素的干预作用。方法:以25名正常对照者、29例寻常型银屑病患者和不同组别HaCaT细胞(空白对照组、IL-17刺激24h组、IL-17刺激36h组、IL-17刺激48h组、紫草素+IL-17组、环孢素A+IL-17组和IL-17组)为研究对象,采用双抗体夹心酶联免疫吸附法(ELISA)检测寻常型银屑病患者血清IL-17水平和HaCaT细胞各组上清液中IL-6、IL-23水平;实时荧光免疫定量-聚合酶链式反应法(RT-PCR)检测各组HaCaT细胞中IL-6和IL-23p19 mRNA表达水平;采用细胞计数盒-8(CCK-8)法检测各组HaCaT细胞活力。结果:与正常对照组比较,银屑病组患者血清IL-17水平明显升高,以重度皮损银屑病组升高最为明显(P < 0.05);IL-17刺激24、36和48h组HaCaT细胞及其培养上清中IL-6和IL-23水平及其mRNA表达水平均高于空白对照组(P < 0.01);紫草素+IL-17组和环孢素A+IL-17组HaCaT细胞及其培养上清中IL-6和IL-23水平及其mRAN表达水平均低于IL-17组(P < 0.05)。与空白对照组比较,其他各组细胞活力差异无统计学意义(P > 0.05)。结论:银屑病患者血清IL-17表达水平升高,尤其是重度皮损银屑病患者血清IL-17表达水平升高明显,IL-17可促进HaCaT细胞分泌IL-6和IL-23,呈时间依赖性,紫草素可抑制IL-17的促炎症作用。

Abstract: Objective: To explore the expression level of serum interleukin-17 (IL-17) in the patients with psoriasis vulgaris and the changes of interleukin-6 (IL-6) and interleukin-23 (IL-23) levels secrered by the HaCaT cells after stimulated with IL-17, and to clarify its clinical significance and the intervention effect of shikonin. Methods: Twenty-five normal controls, 29 patients with psoriasis vulgaris and different groups of HaCaT cells (blank control group,IL-17-24 h group,IL-17-36 h group,IL-17-48 h group,shikonin+IL-17 group,CsA+IL-17 group and IL-17 group) were used as the subjects. The levels of serum IL-17 in the patients with psoriasis vulgaris and the levels of IL-6 and IL-23 in supernatant of HaCaT cells in various groups were measured by double antibody sandwich enzyme-linked immunosorbent assay(ELISA) and real-time polymerase chain reaction RT-PCR was used to detect the expression levels of IL-6 and IL-23 p19 mRNA in HaCaT cells in various groups.At the same time,Cell Counting Kit-8 (CCK-8) method was used to detect the viabilities of HaCaT cells in various groups. Results: The level of serum IL-17 of the patients in psoriasis vulgaris group was increased compared with nomral control group, especially in the severe skin lesion group(P<0.05). The levels of IL-6 and IL-23 in HaCaT cells and supernatant and their mRNA expression levels in IL-17-24 h,IL-17-36 h and IL-17-48 h groups were significantly higher than those in blank control group (P<0.01). The expression levels of IL-6 and IL-23 in HaCaT cells and supernatant and their mRNA expression levels in shikonin+IL-17 and CsA+IL-17 groups were lower than those in IL-17 groups (P<0.05). No statistical differences were found in the cell viabilities between each drug treatment group and blank control group (P>0.05). Conclusion: The expression level of IL-17 in the patients with psoriasis vulgaris is significantly increased,especially in the patients with severe psoriasis vulgaris.IL-17 can promote the secretion of IL-6 and IL-23 in HaCaT cells in a time-dependent manner. Shikonin can inhibit the proinflammatory effect of IL-17.
