DDS: 结肠炎模型小鼠中循环免疫活性细胞的增加会导致肺对细菌内毒素反应的增强

2018-11-19 MedSci MedSci原创

与一般人群相比,患有炎性肠病的患者具有更高的气道高反应性发生率。因此本项研究旨在研究对结肠小鼠中细菌内毒素与肺炎症反应之间的关系。

背景及目的
与一般人群相比,患有炎性肠病的患者具有更高的气道高反应性发生率。因此本项研究旨在研究对结肠小鼠中细菌内毒素与肺炎症反应之间的关系。

方法
研究人员对小鼠用NSAID治疗以制作结肠炎模型。所有小鼠用细菌内毒素处理并在3周后进行尸体剖检。

结果
在用细菌内毒素处理的第21天,结肠炎模型小鼠出现增强的肺部炎症。来自结肠小鼠的肺淋巴细胞显示出促炎细胞因子谱的改变:高表达ICAM1并低表达FoxP3。

结论
与非结肠炎小鼠相比,结肠炎小鼠响应细菌内毒素更加迅速并出现加剧的肺部炎症。来自肺淋巴细胞的促炎细胞因子诱导ICAM1的高表达并抑制CD4+细胞上的FoxP3的表达,本项研究的结果证明结肠炎会加剧肺部炎症。
