JCC:活动性溃疡性结肠炎患者在疾病早期和晚期的黏膜和全身免疫特性有所不同

2019-11-09 不详 MedSci原创

已经有文献报道溃疡性结肠炎[UC]在疾病过程中其免疫发病机制会发生改变。因此,本项研究旨在确定诊断时[早期疾病]和10年后[晚期疾病]患者的黏膜和全身免疫状况。

背景及目标
已经有文献报道溃疡性结肠炎[UC]在疾病过程中其免疫发病机制会发生改变。因此,本项研究旨在确定诊断时[早期疾病]和10年后[晚期疾病]患者的黏膜和全身免疫状况。

方法
研究人员收集了UC患者在疾病早期和晚期发作期间的血清和粘膜活检标本。使用Olink Proseek炎症面板分析血清样本。使用RT-PCR抗菌反应和T辅助细胞分化分析活检组织的mRNA基因表达水平。

结果
研究人员从15例UC患者中发现其在疾病的早期和晚期存在15种血清蛋白。这些蛋白质中的八种在组之间差异表达[Q <0.05]。此外,活检组织中mRNA谱的OPLS-DA可高度区分可预测性较高的早期和晚期疾病[R2 = 0.96,Q2 = 0.89];在两个时间点有42个基因表达差异[Q <0.05]。最后,主成分分析表明,与T辅助基因Th1和Th2相关的基因分别与早期疾病和晚期疾病有关。

结论
活动性UC患者的早期和晚期疾病的粘膜和全身免疫特性有所不同,肠道T细胞从早期Th1型转变为晚期Th2型。
