Abstract

Addiction to methamphetamine (METH) is a global health problem for which there are no approved pharmacotherapies. The adenosine 2A (A2A) receptor presents a potential therapeutic target for METH abuse due to its modulatory effects on striatal dopamine and glutamate transmission. Notably, A2A receptor signalling has been implicated in the rewarding effects of alcohol, cocaine and opiates; yet, the role of this receptor in METH consumption and seeking is essentially unknown. Therefore, the current study used A2A knockout (KO) mice to assess the role of A2A in behaviours relevant to METH addiction. METH conditioned place preference was absent in A2A KO mice compared with wild-type (WT) litterma..
