dc.description.abstract | An adipose-derived peptide hormone, leptin, has a regulatory role in reward-related behaviors produced by drugs of abuse. Although it is known that leptin modulates mesolimbic dopaminergic pathways, little is known about its direct role in the nucleus accumbens (NAcc). In the present study, we measured acute cocaine-induced locomotor activity in the rat and the phosphorylation levels of GSK3beta after bilateral microinjections of leptin into the NAcc core. Interestingly, leptin in the NAcc core significantly disrupts acute cocaine's effects on both locomotor activity and signaling molecules. In order to further confirm the role of GSK3beta in these processes, we microinjected S9 peptide, a small synthetic peptide acting as a competitive inhibitor against phosphorylation site of GSK3beta, followed by leptin co-microinjection, and found that leptin's effects on cocaine were all nullified. These results indicate that leptin in the NAcc core has a negative regulatory role in acute cocaine' effects, and suggest that GSK3beta may play a major role in mediating these processes. | - |
