Role of secretin peptide family and their receptors in the hypothalamic control of energy homeostasis.

Secretin family of peptide hormones is a group of structurally related brain-gut peptides that exert their functions via interactions with the class B1 G protein-coupled receptors (GPCRs). Recent researches of these peptides and receptors in metabolism have been an area of intense focus for the development of promising drug targets as therapeutic potentials for metabolic disorders. The fact that agonists of GLP-1, a member in the family, have already started being used as therapeutics clearly indicates the importance and relevance of further research on the clinical applications of these peptides. This review aims to provide an overview of the current understanding regarding the importance of this family of peptides as well as their receptors in metabolism with special focus on their actions in the hypothalamus. © Georg Thieme Verlag KG Stuttgart · New York.
