Abstract:
:By the use of well-characterized antibodies against porcine dynorphin-A(1-8), an endogenous opioid peptide, and the use of a modified immunofluorescence microscopic technique, dynorphin-A(1-8) stained perikarya, nerve fibres, and nerve terminals were visualized in the rat duodenum. Dynorphin-A(1-8) immunoreactive perikarya were revealed with certainty only in the myenteric plexus, while dynorphinergic nerve fibres could bee seen in the myenteric plexus and circular muscle layer, but not in the longitudinal muscle layer and submucous plexus. Dynorphin-A(1-8) immunofluorescent nerve endings were in close contacts with submucosal blood vessels, probably arterioles, and Brunner's gland cells. These findings suggest that the opioid peptide dynorphin-A(1-8) might be synthetized within myenteric plexus perikarya of the rat duodenum and that it might modulate the peristaltic activity, intestinal blood pressure, and production of mucopeptides synthetized within Brunner's gland cells.
