Calcitonin gene-related peptide (CGRP) content and CGRP receptor binding sites in discrete forebrain regions of alcohol-preferring vs. -nonpreferring rats, and high alcohol-drinking vs. low alcohol-drinking rats



Calcitonin gene-related peptide (CGRP) content and CGRP receptor binding sites in discrete forebrain regions of alcohol-preferring vs. -nonpreferring rats, and high alcohol-drinking vs. low alcohol-drinking rats



Brain Research 690(2): 249-253



This study showed that alcohol-preferring (P) rats and high alcohol-drinking (HAD) rats possess fewer calcitonin gene-related peptide (CGRP) receptor binding sites than their respective controls in the central amygdaloid nucleus (CeA) which is known to be related to anxiety. Since P and HAD rats are selectively bred for high alcohol preference, and alcohol can produce anxiolytic effect, one can postulate that P and HAD rats preferentially drink alcohol in order to obtain its anxiolytic effect. This study supports a hypothesis that deficit of CGRP receptors in the CeA of P and HAD rats may contribute to alcohol preference.
