5-hydroxytryptamine release into human jejunum by cholera toxin.

Abstract

Thus, cholera toxin induced a secretory state and promoted the release of 5-hydroxytryptamine into the intestinal lumen, but quantitative changes in urinary 5-hydroxyindoleacetic acid were not detectable. As an intestinal secretagogue, these findings suggest that 5-hydroxytryptamine may play a part in mediating cholera toxin induced secretion in humans.
