Riassunto

One of the phylogenetically oldest hormones, somatostatin isa regulatory peptide with remarkable characteristics. It isa nonclassical neurotransmitter discovered less than 20years ago both in the central nervous system and in thegastroenteropancreatic system. It regulates the secretion ofboth pituitary and digestive hormones, it ensures nutrienthomeostasis and it has therapeutic uses. This volume dealswithall these aspects.
