Tight junction proteins in inflammatory bowel diseases

In microscopic colitis and in ulcerative colitis before and after therapy, mechanisms of epithelial barrier dysfunction are analyzed using impedance spectroscopy, scanning conductance, confocal microscopy, Western blotting, and quantitative RT-PCR analysis. During this, the expression of the tight junction molecules ZO1, occludin, tricellulin, and supposedly important claudins are characterized. In addition, apoptosic rates and epithelial lesions are assayed.

Furthermore, mechanisms of the inflammatory regulation of epithelial tight junctions and their constituent molecules are studied in HT-29/B6 colon cells. Parameter are half life, subcellular distribution, mRNA expression, translational efficiency as effectd by by miRNAs, promoter activity, and intracellular signaling pathways.
