TJs seal the intercellular spaces between cells and regulate paracellular transport of water, ions, and solutes (Proksch et al.
As claudin-1 has two extra cellular loops that display variability in the distribution and number of charged residues, it is the major determinant of ionic selectivity in paracellular transport processes (Gonzalez et al.
Therefore the enhancement of paracellular transport path is most likely to be responsible for increased passive transport of calcium in the intestine of rats fed high calcium diet.
In particular, these devices demonstrate enhanced cellular adhesion and the paracellular transport of the therapeutic molecules that they are fabricated to deliver.
Recently these structures that give rise to paracellular transport have been shown to contain a relatively large amount of protein.
Alessio Fasano, zonulin appears to be involved in many disease states in which leakage occurs via paracellular transport across epithelial and endothelial tight junctions (tj), and thus may play an important potential role in the treatment of autoimmune diseases.
The adjacent cells adhere through tight junctions formed at the apical side of the monolayer, which can discriminate the transcellular and paracellular transport of drugs across the epithelial layer (Yamashita et al.
However, up to now it has not been fully revealed whether the increased macromolecular passage is mainly due to transcellular or paracellular transport.
Alessio Fasano, zonulin appears to be involved in many disease states in which leakage occurs via paracellular transport across epithelial and endothelial tight junctions, and thus may play an important potential role in the treatment of autoimmune and inflammatory diseases.

Tight junctions are cell-to-cell connections found in the epithelial and endothelial layers that regulate paracellular transport across the natural tissue boundaries that comprise nasal and intestinal mucosa, blood vessels, and the blood-brain barrier.
