摘　　要：目的通过检测白细胞介素35受体(IL-35R)两亚基糖蛋白130(gp130)、白细胞介素12受体β2(IL-12Rβ2)及信号转导和转录激活因子(STAT)1、STAT4在口腔扁平苔藓(OLP)组织中的表达,探讨IL-35R在OLP病损形成和发展中的作用及意义。方法收集41例OLP组织(OLP组)和15例正常口腔黏膜组织(对照组)为研究对象。采用实时荧光定量聚合酶链反应检测组织中gp130、IL-12Rβ2、STAT1、STAT4 mRNA的表达水平,免疫组织化学(IHC)检测组织中gp130、IL-12Rβ2蛋白的表达及分布,并分析gp130、IL-12Rβ2蛋白表达与OLP临床特征的关系。结果1)OLP组gp130、IL-12Rβ2、STAT1、STAT4 mRNA的相对表达量均高于对照组(P<0.05)。2)OLP组gp130、IL-12Rβ2蛋白的阳性表达率均高于对照组(P<0.05),且gp130、IL-12Rβ2蛋白在OLP组织中的表达呈正相关(r=0.984,P<0.001)。3)糜烂型OLP组织gp130、IL-12Rβ2蛋白的阳性表达率高于非糜烂型(P<0.05)。结论IL-35R及STAT在OLP组织中表达上调,且IL-35R的表达与OLP的临床分型有关,提示IL-35R可能在OLP病损形成及发展中起重要作用。Objective To investigate the expression of glycoprotein 130(gp130)and interleukin 12 receptorβ2(IL-12Rβ2)in two subunits of interleukin-35 receptor(IL-35R),singal transducer and activator of transcription(STAT)1 and STAT4 in oral lichen planus(OLP)tissues,and to explore the role and significance of IL-35R in the formation and development of OLP lesions.Methods Totally 41 samples of OLP tissues(OLP group)and 15 samples of normal oral mucosa(control group)were collected.The expression levels of gp130,IL-12Rβ2,STAT1,STAT4 mRNA in the tissues were detected by real-time fluorescent quantitative polymerase chain reaction and the distribution and expression of protein gp130 and IL-12Rβ2 were detected by immunohistochemistry.The potential relationship between gp130 and IL-12Rβ2 and clinical features of OLP was analyzed.Results 1)The expression levels of gp130,IL-12Rβ2,STAT1 and STAT4 mRNA in the OLP group were significantly higher than those in the control group(P<0.05).2)The positive expression rates of gp130 and IL-12Rβ2 protein in the OLP group were higher than those in the control group(P<0.05).The expression of gp130 and IL-12Rβ2 proteins in OLP tissues were positively correlated(r=0.984,P<0.001).3)The expression rates of gp130 and IL-12Rβ2 protein in erosive OLP tissues were significantly higher than those in non-erosive ones(P<0.05).Conclusion The expression of IL-35R and STAT is upregulated in OLP tissues,and the expression of IL-35R is related to the clinical classification of OLP,suggesting that IL-35R might play an important role in the formation and development of damage OLP lesions.
