Paracellular permeability and tight junction regulation in gut health and disease
Nature reviews: Gastroenterology & hepatology, 2023 Epithelial tight junctions define the paracellular permeability of the intestinal barrier. Molecules can cross the tight junctions via two distinct size-selective and charge-selective paracellular pathways: the pore pathway and the leak pathway.
