Abstract

<p>The delta opioid receptor (DOP) belongs to the G protein-coupled receptor family and is abundant in the limbic system. In recent years, consistent with their distribution, they have been suggested to be involved in the regulation of emotional behavior. In particular, DOP agonists have been shown to exhibit antidepressant and anxiolytic-like effects, and clinical trials are underway as targets for the development of new psychotropic drugs with mechanisms of action different from those of existing monoamine drugs. In this article, we review the roles and mechanisms of DOP in emotion regulation that are being elucidated in basic studies using rodents, and also introduce the current status of its clinical application.</p>
