Caerulein and its analogues: neuropharmacological properties.

abstract：:Previously, calcitonin gene-related peptide (CGRP) decreased food intake when administered ICV but not when administered peripherally to rats. Amylin, which has a close structural homology to CGRP, reduced food intake administered IP at concentrations higher than those previously tested for CGRP. We examined the effec...
