摘要 目的分析溃疡性结肠炎患者外周血单个核细胞Toll样受体4(TLR4)的表达及其与血清TNF-α和IL-6浓度的相关性,初步探讨TLR4在溃疡性结肠炎发病中的作用。方法采用实时荧光定量PCR方法检测60例溃疡性结肠炎患者外周血单个核细胞内TLR4 mRNA的水平,并采用双抗体夹心酶联免疫吸附法(ELISA)检测血清TNF-α和IL-6的浓度。另取50例正常人作为对照组。结果溃疡性结肠炎患者较对照组的外周血中单个核细胞TLR4 mRNA水平差异有显著性,血清TNF-α和IL-6浓度较对照组明显增高(P<0.01),TLR4基因表达与血清炎症因子TNF-α和IL-6浓度变化呈正相关(r值分别为0.735和0.641,均P<0.05)。结论 TLR4及其介导的天然免疫应答在溃疡性结肠炎发病机制中起重要作用,其机制可能是通过上调TLR4的表达促使炎症因子产生和分泌而介导溃疡性结肠炎的发病。
