| Abstract | Calcitonin gene-related peptide (CGRP) binding sites have been identified in homogenates from the rat brain and spinal cord. Autoradiography with [125I]rat CGRP (rCGRP) revealed high grain density over the lateral hypothalamus, vestibular nuclei, colliculi, medial geniculate body, corpus mamillare and the molecular layer of the cerebellum which lacked binding sites for [125]salmon calcitonin (sCT). In contrast, no rCGRP labeling was seen over the anterior and dorsomedial hypothalamus which showed high sCT binding. The different regional distribution of rCGRP and sCT binding sites indicates that the structurally related peptides interact with separate receptors. The overlap between the localization of CGRP binding sites and endogenous CGRP in many regions of the central nervous system suggests that CGRP exerts unique physiological functions in the central nervous system. |
