Secretion of goblet cell serine proteinase, ingobsin, is stimulated by vasoactive intestinal polypeptide and acetylcholine
Research output: Contribution to journal › Journal article › Research › peer-review
Ingobsin is localized to the intestinal goblet cells in the rat and in man. In the present study, we investigated the effect of vasoactive intestinal polypeptide (VIP) and acetylcholine on the secretion of ingobsin from the proximal duodenum. Intravenous infusion of VIP or acetylcholine increased the concentration of ingobsin in duodenal secretion, while the concentration in the duodenum was unchanged. Simultaneous infusion of VIP and acetylcholine increased the concentration of ingobsin in duodenal secretion and decreased the concentration of ingobsin in the duodenum. This study demonstrates that secretion of ingobsin from the proximal duodenum is exocrine and can be stimulated by VIP and acetylcholine.
