Article Title: Decreased Immunoreactivity of the Melanocortin Neuropeptide α -Melanocyte-Stimulating Hormone ( α -MSH) After Chronic Ethanol Exposure in Sprague-Dawley Rats
Article Snippet: More recently we found that site-directed infusion of a selective MC4R antagonist into the NAc increased ethanol drinking in Sprague–Dawley rats ( Carvajal et al., 2007 ), a finding that suggests that endogenous α -MSH may negatively modulate the rewarding properties of ethanol via MC4R signaling in the NAc.
