α2-Adrenergic receptor modulates 5-HT2A-mediated behavioral effects of MDMA and psilocybin in mice.

Mol Psychiatry July 7, 2026 Axel F. Rosado, Abigail L. Yu, Jen-Hau Yang et al.

Classic serotonergic psychedelics such as psilocybin act as agonists at cortical serotonin (5-HT) 2A receptors (5-HT 2A R), inducing psychedelic effects in humans and head-twitch responses (HTRs) in rodents. Another class of psychedelic drugs called entactogens, exemplified by MDMA, function primarily as monoamine releasers and typically evoke minimal HTR despite causing serotonin release. The...

Classification of psychedelics and psychoactive drugs based on brain-wide imaging of cellular c-Fos expression

Nature Communications February 12, 2025 Farid Aboharb, Pasha A. Davoudian, Ling-Xiao Shao et al. 19 citations

Psilocybin, ketamine, and MDMA are psychoactive compounds that exert behavioral effects with distinguishable but also overlapping features. The growing interest in using these compounds as therapeutics necessitates preclinical assays that can accurately screen psychedelics and related analogs. We posit that a promising approach may be to measure drug action on markers of neural plasticity in...

5-MeO-DMT modifies innate behaviors and promotes structural neural plasticity in mice.

Neuropsychopharmacology : official publication of the American College of Neuropsychopharmacology August 1, 2023 Sarah J. Jefferson, Ian Gregg, Mark Dibbs et al. 57 citations

Serotonergic psychedelics are gaining increasing interest as potential therapeutics for a range of mental illnesses. Compounds with short-lived subjective effects may be clinically useful because dosing time would be reduced, which may improve patient access. One short-acting psychedelic is 5-MeO-DMT, which has been associated with improvement in depression and anxiety symptoms in early phase...
