1、ChineseJournalofPracticalInternalMedicineSep.2014Vo1.34No.9論著IgA腎病外周血單個(gè)核細(xì)胞T—betGATA一3ROR一t和Foxp3mRNA的表達(dá)及其意義研究方明,徐顥,王可平,劉越堅(jiān),陳淑妮,林洪麗D01:10.7504/nk2014080302中圖分類號:R692.3文獻(xiàn)標(biāo)志碼:A摘要:目的在mRNA水平探討IgA腎病患者外周血Th1、Th2、Th17和Treg細(xì)胞免疫失衡及其與IgA腎病(IgAN)牛津分型的相關(guān)性。方法以2010年l1月至2011年11月在大連醫(yī)科大學(xué)附屬第一醫(yī)院腎內(nèi)科經(jīng)腎活檢病理確診的原發(fā)性
2、IgAN患者為研究對象,應(yīng)用實(shí)時(shí)熒光定量PCR檢測IgAN患者(20例)和健康對照組(10名)外周血單個(gè)核細(xì)胞的特異性轉(zhuǎn)錄因子T—bet、GATA.3、ROR一"yt、Foxp3的mRNA表達(dá)水平。結(jié)果與對照組比較,IgAN組ROR一-/t表達(dá)明顯升高(P<0.05)、Foxp3表達(dá)明顯下降(P<0.05),且ROR一~t/Foxp3比值明顯升高(P<0.05);而T—bet、GATA一3的表達(dá)與對照組相比差異無統(tǒng)計(jì)學(xué)意義(P>0.05)。按IgAN牛津分型病理指標(biāo)分組結(jié)果比較顯示,M1組T.bet表達(dá)及T.bet/GATA一3的比值較M0組明顯升高(P<0.05)。進(jìn)一步相
3、關(guān)分析顯示,IgAN組Tet表達(dá)與系膜增殖積分呈顯著正相關(guān)(r=0.541,P<0.01)。s1組T—bet表達(dá)顯著升高(P<0.01),ROR一t表達(dá)無明顯差異(P>0.05),T.bet/ROR一t比值明顯升高(P<0.05);而GATA一3、Foxp3無變化(P>0.05)。結(jié)論IgAN患者外周血單個(gè)核細(xì)胞在mRNA水平出現(xiàn)了偏向Thl7極化,而Treg的應(yīng)答被抑制。IgAN系膜增殖程度與Thl極化呈正相關(guān),而腎小球節(jié)段硬化的Th1/Thl7的比值明顯升高。關(guān)鍵詞:IgA腎病;輔助性T細(xì)胞;轉(zhuǎn)錄因子T-bet,GATA-3,ROR-andFoxp3mRNAlevelso
