Lr. Forte et Fk. Hamra, GUANYLIN AND UROGUANYLIN - INTESTINAL PEPTIDE-HORMONES THAT REGULATE EPITHELIAL TRANSPORT, News in physiological sciences, 11, 1996, pp. 17-24
Guanylin and uroguanylin are peptides that activate a membrane guanyla
te cyclase and control salt and water transport. intestinal bacteria s
ecrete toxins that mimic the actions of these peptides, causing a secr
etory form of diarrhea. Stimulation of guanylin/uroguanylin receptors
in the kidney increases salt excretion. Thus guanylin and uroguanylin
may regulate salt and water homeostasis.
