Effects of glucagon, insulin, amylin and CGRP on feeding.

The roles of the pancreatic peptides glucagon, insulin, and amylin in the inhibitory control of feeding are reviewed. Calcitonin gene-related peptide (CGRP) is also included because it is structurally and functionally related to amylin and because known amylin and CRRP receptors are activated by both peptides. Glucagon-like peptide 1, in contrast, is structurally distinct from pancreatic glucagon and does not cross-react with glucagon receptors, so it is not considered. Several detailed reviews of the feeding effects of these peptides have appeared recently; where appropriate, these are cited rather than the primary literature.
