Opioid Receptors and Depression

Tricyclic antidepressants (TCAs) have been reported to interact with the Opioid Receptor system, but their pharmacological activity at opioid receptors has not yet been elucidated.

We would like to share a recent publications that sheds more light on the mystery. Our purified rabbit ployclonal phosphoERK1/2 Antibody is also referenced.

Pierluigi Onali, Simona Dedoni and Maria C. Olianas. Direct Agonist Activity of Tricyclic Antidepressants at Distinct Opioid Receptor Subtypes. JPET January 2010 vol. 332 no. 1 255-265 .

At the cloned μ-opioid receptor, TCAs showed low affinity and no significant agonist activity. These results show that TCAs differentially regulate opioid receptors with a preferential agonist activity on either δ or κ subtypes and suggest that this property may contribute to their therapeutic and/or side effects.
