Cannabinoid and Heroin Activation of Mesolimbic Dopamine Transmission by a Common µ 1 Opioid Receptor Mechanism

Tanda, Gianluigi, Pontieri, Francesco E., Chiara, Gaetano Di·1997·Science

Abstract

The effects of the active ingredient of Cannabis , Δ 9 -tetrahydrocannabinol (Δ 9 -THC), and of the highly addictive drug heroin on in vivo dopamine transmission in the nucleus accumbens were compared in Sprague-Dawley rats by brain microdialysis. Δ 9 -THC and heroin increased extracellular dopamine concentrations selectively in the shell of the nucleus accumbens; these effects were mimicked by the synthetic cannabinoid agonist WIN55212-2. SR141716A, an antagonist of central cannabinoid receptors, prevented the effects of Δ 9 -THC but not those of heroin. Naloxone, a generic opioid antagonist, administered systemically, or naloxonazine, an antagonist of μ 1 opioid receptors, infused into the ventral tegmentum, prevented the action of cannabinoids and heroin on dopamine transmission. Thus, Δ 9 -THC and heroin exert similar effects on mesolimbic dopamine transmission through a common μ 1 opioid receptor mechanism located in the ventral mesencephalic tegmentum.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
