Deletion of Melanin-Concentrating Hormone Receptor-1 gene accentuates D-amphetamine-induced psychomotor activation but neither the subsequent development of sensitization nor the expression of conditioned activity in mice.

Abstract excerpt

The present study aimed to test the hypothesis that mice lacking the MCHR1 receptor (Melanin-Concentrating Hormone Receptor-1) present an elevated vulnerability towards the neurobehavioural effects of D-amphetamine, presumably due to previously established up-regulations of dopamine D1 receptors...
