WebFigure 14-3 summarizes the major mechanisms for the synthesis and metabolism of histamine. Biosynthesis is performed in one step by the enzyme l-histidine … WebThe Caco-2 cells have been used as a model system to study the pathways of diamine oxidase secretion by the intestinal epithelium. When grown in Transwell filter chamber devices, the polarized cell monolayers released the enzyme preferentially into the basal chamber. Heparin (1–10 USP U/mL) rapidly induced a marked stimulation of enzyme …
