Mice lacking the serotonin transporter do not respond to the behavioural effects of psilocybin.
European journal of pharmacology – March 15, 2025
Summary
Psilocybin's therapeutic effects may depend on a functioning serotonin transporter (5-HTT) in the brain. When researchers removed this transporter in mice, the animals showed no response to psilocybin's typical effects on behavior and movement.

Psilocybin history, action and reaction: A narrative clinical review
Journal of Psychopharmacology – August 31, 2023
Summary
Psilocybin, a potent hallucinogen, holds modest promise in psychiatry for treating anxiety and depression, with early data also suggesting benefits for alcohol use disorders. While supervised psilocybin therapy in medicine typically yields mild, transient adverse effects, and severe events are uncommon, one recent clinical trial observed increased suicidal ideation. This critical finding from psychedelics and drug studies highlights complex psychological considerations for this compound, derived from natural alkaloids, as it moves towards broader therapeutic application.

Resurrecting Ancestral Familial Health: A Role for Psilocybin?
The Family Journal – August 09, 2024
Summary
A novel approach suggests high-dose psilocybin, a compound derived from chemical synthesis and alkaloids, could revolutionize family Psychology. This perspective, informed by Developmental psychology and Social psychology, proposes a family-centered therapy where a psychotherapist integrates psychedelics with interventions like family constellations. Evidence from Drug Studies indicates this model can realign modern families with our evolved social mammalian physiological design, fostering empathy, connection, and well-being. It offers a path to heal intergenerational trauma and enhance family systems.

The psychedelic renaissance: can psilocybin possibly combat depression?
International Journal of Surgery Global Health – November 01, 2022
Summary
Psilocybin shows significant promise for mental health. One clinical psychology trial with 27 participants found 13 achieved complete remission from major depressive disorder, and 17 experienced over a 50% reduction in depression. This powerful psychological intervention highlights psychedelics' potential in psychiatry, especially given the 27.6% rise in depression across the population. Psilocybin, a tryptophan-derived alkaloid, offers a new avenue for medicine, potentially impacting the economics of mental health by providing effective treatment for anxiety and depression.
