Outline of Final Research Achievements |
The aim of this study was to learn how reciprocal regulation between the cell-cell adhesion of tight junctions (TJs) and the apical membrane defines a unified epithelial system via the cytoskeleton and cell signaling in epithelial cell sheets. Claudins, the primary constituents of TJs, have critical roles as a structural component of the paracellular barrier. A recent crystallographic structural analysis revealed the molecular structure of claudin. Our recent knockout mouse analyses elucidated the physiological relevance of the paracellular barriers/permeability in many biological systems. On the other hand, we recently discovered that a network of microtubules existed just below the apical membrane of the epithelial cell sheet. Since this apical microtubule network appeared to be connected to TJs, we propose that the TJ-apical complex is critical for organizing the TJ and apical membrane systems, and thus for creating and regulating the epithelial barrier and biological systems.
