Opioid-based treatments of depression: from cells to patients


Half of patients with major depressive disorder (MDD) are inadequately treated by available interventions, likely as a result of the heterogeneity of depression and the lack of biomarkers for stratification into distinct subtypes. We discovered that the atypical antidepressant tianeptine is a partial agonist at the mu opioid receptor (MOR). The acute and chronic antidepressant-like behavioral effects of tianeptine in mice require MOR. While tianeptine produces opiate-like behavioral effects such as analgesia and reward, it does not lead to tolerance or withdrawal in mice. Unlike fluoxetine, tianeptine induces rapid antidepressant-like effects in mice after as little as one week of treatment.

Endogenous opioids act at MOR in response to social rejection, and this response is blunted in some depressed individuals. In addition, healthy individuals with high rejection sensitivity (RS) also show reduced MOR activation. We hypothesize that a subgroup of MDD patients with deficient opioid receptor signaling will better respond to pharmacological interventions specifically targeting this biological mechanism, and we have initiated a clinical trial to test this hypothesis.
