1、南通大学学报(医学版)·520·JournalofNantongUniversity(Medica1Sciences)2013:33(6急慢性乙肝患者外周血Th17与Treg细胞的表达朱轶晴,汤伟,孙强(南通大学医学院免疫学系,南通226001;。南通大学附属医院感染科)【摘要]目的:探讨急慢性乙型肝炎患者外周血Thl7与Treg细胞的表达情况。方法:采集17例慢性乙肝(chmniehepatitisB,CHB)患者、13例急性/]~:(acutehepatitisB,AHB)患者和l4例健康者(对照组)外周血,流式细
2、胞术分析Th17和Treg细胞的频率.实时荧光定量PCR法检测外周血单个核细胞中转录因q~(retinoicacidreceptor—relatedorphanan—clearreceptoryt,RORyt)~1(forkheadfamilytranscriptionfactor3,FoxP3)~mRNA表达水平。结果:AHB组和CHB组外周血Thl7细胞频率和RORTtmRNA表达水平均高于对照组,但CHB组低于AHB组(尸<0.05);CHB组外周血Treg细胞频率和FoxP3mRNA表达水平均显著高于AHB组和
3、对照组.而AHB组和对照组之间差异无统计学意X(P>O.05)结论:急慢性乙肝患者外周血中存在Th17和Treg细胞表达异常,提示Th17和.rreg细胞可能在乙型肝炎的发病机制中起着一定的作用[关键词]急性乙型肝炎;慢性乙型肝炎;乙型肝炎病毒;Th17细胞;Treg细胞【中图分类号]R512.6+2[文献标志码】A【文章编号]1674—7887(2013)06—0520—04ExpressionlevelsofThelpertype17andTregulatorycellsintheperipheralbloodof
