Literature

Research context

Larazotide was derived from the zonula occludens toxin of Vibrio cholerae and acts as a competitive antagonist at the zonulin receptor. Published work measures transepithelial electrical resistance in Caco-2 monolayers, actin cytoskeleton rearrangement at the tight junction, and paracellular macromolecule flux. Supplied as the acetate salt.
