Brain-gut-skin peptides: An update overview.

Abstract

The authors present an overview of the main amphibian peptide families mainly derived from the skin and mostly discovered by Erspamer and his associates. The studies of the peptides do not only promote the understanding of their chemical, metabolical and physiological features of those molecules in amphibians, but also contribute to progress in our knowledge of the corresponding mammalian counterparts. Particular reference is made on sauvagine, tachykinin, bombesin and dermorphin families, offering new data mostly from personal contributions to this field.
