Dynamics and functions of tight junctions
WebTight junctions, also known as occluding junctions or zonulae occludentes (singular, zonula occludens), are multiprotein junctional complexes whose canonical function is to prevent leakage of solutes and water and seals between the epithelial cells. They also play a critical role maintaining the structure and permeability of endothelial cells. Tight … Webthe tight junction is a passive process that occurs along concentration gradients.
