Comparative analysis of theophylline and cholera toxin in rat colon reveals an induction of sealing tight junction proteins
Claudin tight junction proteins have been identified to primarily determine intestinal epithelial barrier properties. While functional contribution of single claudins has been characterized inExpand

Increased paracellular permeability of tumor-adjacent areas in 1,2-dimethylhydrazine-induced colon carcinogenesis in rats
Objective: The morphology and functions of the proximal and distal large intestine are not the same. The incidence of colorectal cancer in these regions is also different, as tumors more often appearExpand

Molecular Characterization of Barrier Properties in Follicle-Associated Epithelium of Porcine Peyer's Patches Reveals Major Sealing Function of Claudin-4
The pig represents a preferred model for the analysis of intestinal immunology. However, the barrier of the follicle-associated epithelium (FAE) covering porcine Peyer's patches (PP) has not yet beenExpand

Claudin expression in follicle‐associated epithelium of rat Peyer's patches defines a major restriction of the paracellular pathway
Members of the tight junction protein family of claudins have been demonstrated to specifically determine paracellular permeability of the intestinal epithelium. In small intestinal mucosa, which isExpand

[Effect of cholerogen and protamine on tight junctions of rat enterocytes and colonocytes].
AIM Study of tight junction state and ultrastructure changes of rat jejunum enterocytes and colon colonocytes under the effect of cholerogen and protamine. MATERIALS AND METHODS Cholerogen (choleraExpand
The study of barrier characteristics of Peyer’s patches epithelium in rats
The aim of the study was to investigate the barrier function of Peyer’s patches epithelium, which covers the clusters of organized lymphoid tissues in the small intestinal. We used the Ussing chamberExpand
