Altered dopamine D1 and D2 receptor mRNA expression in mesencephalon from mice exposed to repeated treatments with methamphetamine and cannabinoid CB1 agonist methanandamide.
OBJECTIVES: In our previous studies we found that both acute administration of CB1 receptor agonist methanandamide and repeated methanandamide pre-treatment prior to methamphetamine challenge dose elicited increase in the CB1 receptor mRNA expression in the mouse mesencephalon. As a reciprocal cross-talk is reported between the cannabin.....
