2、mphocytesTh)在OLP的发病过程中具有重要作用,本研究旨在进一步探索OLP患者局部病损组织中辅助性T细胞亚群Thl7细胞和Ikg细胞的作用。方法:纳入43例OLP患者和13例健康志愿者。采用实时定量PCR法检测局部病损组织中,I’}l17和Treg细胞的特征性转录因子RORyr和FOXP3的表达,采用GraphPadPrism5软件对其表达差异进行统计学分析。结果:OLP局部病损组织中转录因子R0RT和FOXP3的表达显著高于正常黏膜组织.而且均与OLP的临床分型密切相关。萎缩糜烂型OLP组病损组织中R0R^y1I0xP3比值显著高于网状型OLP组和健康对照组.而网状型OLP组的R
3、ORyr/FOXP3比值虽然高于对照组,但差异无显著性。结论:Th17细胞和Treg细胞均参与OLP的局部免疫反应;同时,Th17/Treg失衡也参与了重症型OLP的致病过程,且表现为Th17细胞优势【关键词】FOXP3;ROR~T;Th17;Treg;口腔扁平苔藓【中图分类号】R781.5【文献标志码]AExpressionsofRORyrandFOXP3andclinicalsignificanceinpatientswithoralfichenplanusXIESan—xiang,FENGⅡn2,ZHUSheng-rong,DINGLei。.CenterofStomatology,To
