JCC: 早发性或长期炎症性肠病患者肠粘膜γδT细胞的表征及其与临床表现关系

2019-08-03 不详 MedSci原创

炎症性肠病[IBD]是一种慢性炎性肠道疾病,且没有明确的病因。传统上,失调的适应性免疫反应发挥重要作用,由于γδT细胞的众所周知的可塑性,我们研究了它们与健康受试者相比在早发和长期IBD患者的肠粘膜中的发生率,表型特征和效应功能。

背景和目的
炎症性肠病[IBD]是一种慢性炎性肠道疾病,且没有明确的病因。传统上,失调的适应性免疫反应发挥重要作用,由于γδT细胞的众所周知的可塑性,我们研究了它们与健康受试者相比在早发和长期IBD患者的肠粘膜中的发生率,表型特征和效应功能。

方法
研究人员收集了30例克罗恩病溃疡性结肠炎患者的新鲜活组织检查并进行流式细胞术分析细胞表型。

结果
研究人员发现早期和晚期IBD患者组织中Vδ1T细胞的比例降低(分别为2.24%和1.95%,而健康组织为5.44%),但晚期IBD患者肠道中Vδ2T细胞的比例增加(3.19%);早期患者为1.5%,健康组织为1.65%。浸润的Vδ2T细胞具有显着的效应记忆和终末分化的表型,并且产生升高的肿瘤坏死因子-α[TNF-α]和白细胞介素-17 [IL-17]水平。组织Vδ2T细胞的频率与炎症反应的程度和IBD的严重程度相关。

结论
本项研究表明IBD患者的组织Vδ1T细胞减少,而IBD患者的肠道中Vδ2T细胞增加,并促成TNF-α的产生。
