Dialing Out the Hallucinogenic Effect of Psychedelics — BioCentury’s Science Spotlight
Researchers at Sichuan University have identified distinct signaling pathways that separate the hallucinogenic and therapeutic actions of psychedelic compounds. By comparing classic psychedelics with non‑hallucinogenic analogues, they showed that 5‑HT2A‑mediated non‑canonical Gi signaling drives hallucinations, while canonical Gq signaling underlies therapeutic benefits. This mechanistic split suggests it may be possible to design psychedelics that retain antidepressant or anxiolytic effects without perceptual disturbances. The findings were published in Nature and could reshape drug‑development pipelines.
