摘要:
Methods for detecting intestinal cell barrier dysfunction in a patient are disclosed. In one method, patient intestinal epithelial cells (lECs), oropharyngeal epithelial cells (OECs) or buccal epithelial cells (BECs) are stained with detectable probes specific against caspase-1 and caspase-3&7, and the cells are viewed for the presence of elevated levels of caspase-1, as evidence by a significantly higher ratio of caspase-1 marker to caspase-3&7, as an indicator of cell barrier dysfunction. In a second method, in situ images of a patient's lEC's, OECs or BECs are obtained by probe-based confocal laser endomicroscopy (pCLE), and images are analyzed for density of cell gaps. Also disclosed is a probe composition for use in detecting intestinal cell barrier dysfunction.

公开了检测患者肠细胞屏障功能障碍的方法。 在一种方法中,患者肠上皮细胞(IEC),口咽上皮细胞(OEC)或颊上皮细胞(BEC))用对caspase-1和caspase-3和7的特异性的可检测的探针进行染色,并观察细胞存在升高的 胱天蛋白酶-1的水平,作为caspase-1标记物与半胱天冬酶-3和7的显着较高比例的证据,作为细胞屏障功能障碍的指标。 在第二种方法中,通过基于探针的共聚焦激光显微镜(pCLE)获得患者的IEC,OEC或BEC的原位图像,并分析图像的细胞间隙的密度。 还公开了用于检测肠细胞屏障功能障碍的探针组合物。
