description

Social factors have a dual influence on addictive disorders. While social defeat stress in rodents increases the response to drug reward, positive social conditions, such as pair housing, increase stress resilience. The objective of the present study was to confirm whether oxytocin (OT) mediates this social buffering. To this end, male mice were housed in pairs and administered the OT receptor antagonist atosiban prior to each stress episode or for ten days after the stress protocol. The response to cocaine was assessed using a conditioned place preference paradigm. Our results confirmed that OT activity mediates the protective effect of pair housing and highlights its therapeutic potential.
