Anesth Analg:血管内皮细胞糖萼结构状态与脓毒症小鼠病理状态相关

内皮表层(ESL)调节血管通透性维持血流动力学稳定。糖萼(GCX)是一种复杂而脆弱的超微结构,是内皮表层(ESL)的重要组成部分。糖萼(GCX)的异常被认为可触发病理性渗透增加。在本实验中,我们对重要器官中糖萼(GCX)的形态和功能特性进行综合分析。

背景与目的:内皮表层(ESL)调节血管通透性维持血流动力学稳定。糖萼(GCX)是一种复杂而脆弱的超微结构,是内皮表层(ESL)的重要组成部分。糖萼(GCX)的异常被认为可触发病理性渗透增加。在本实验中,我们对重要器官中糖萼(GCX)的形态和功能特性进行综合分析。

方  法:我们使用电镜(EM)和活体显微镜检(IVM)分析了ESL和GCX的结构。我们还比较了糖苷酶处理组和对照组小鼠皮肤ESL的形态学变化。使用综合方法分析了脂多糖诱导脓毒症小鼠内皮的形态和功能、白细胞-内皮相互作用的病理生理特征、血管通透性。

结  果:我们使用活体镜检将ESL的明亮部分确定为GCX,并使用形态学和生化方法证实了我们的观察。我们发现在脓毒症小鼠中,EM成像分析(0.98±2.08nm对70.68±36.36nm,P <0.001)和IVM成像分析(0.36±0.15μm对1.07±1.0μm)中,GCX比非脓毒症对照组更薄0.39μm,P <0.001)。与对照组相比(低于检测值下限,P<0.001),在脓毒症条件下,syndecan-1作为GCX代表性的核心蛋白以较高的速率释放到血清中(7.33±3.46ng / mL)。白细胞-内皮相互作用显着增多被定义为白细胞流动或黏附增多,在体内糖萼(GCX)脱落后也观察到组织间隙超渗透。

结  论:使用IVM,我们可看见ESL的明亮部分,随后使用EM确认为糖萼(GCX)。严重败血症引起糖萼(GCX)降解,伴随着syndecan-1核心蛋白的脱落和白细胞-内皮相互作用的增加影响血管通透性。我们在在体模型描述了一种解释糖萼(GCX)结构与功能关系的新方法。
