Contribution of the Serotonin 5-HT2A Receptor to the Therapeutic Effect of Psilocin on Social Behavior Deficits in Mice Repeatedly Exposed to Social Defeat Stress

ABSTRACT Psychedelics such as psilocybin and lysergic acid diethylamide (LSD) exert hallucinogenic effects through stimulation of serotonin 5-HT2A receptors (5-HT2ARs) in the cerebral cortex. In recent years, numerous reports have demonstrated that psychedelics are effective in treating various psychiatric disorders such as major depressive disorder (MDD), t...

Phase 1 trial suggests benefit of psilocybin in OCD treatment

A Phase 1 trial comprising 15 patients has found that repeated high-dose administration of psilocybin was more effective than low-dose psilocybin or placebo in reducing symptoms of obsessive-compulsive disorder (OCD). Psilocybin was generally well-tolerated, with no reports of serious adverse events.

Investigating the impact of serotonergic psychedelic drugs, MDMA and ketamine on social cognition in psychiatric disorders: A scoping review.

Interest in psychedelic drugs has increased rapidly because of their potential therapeutic role in psychiatric disorders. Impairments in the sociocognitive skills needed to build and maintain social relationships are prominent features of many psychiatric and neurodevelopmental disorders. Emerging evidence suggests that compounds such as 3,4-methylenedioxyme...

Efficacy in Relapse Prevention: Psilocybin in Alcohol Use Disorder With Depressive Symptoms

Up to 40% of individuals with alcohol use disorder (AUD) experience depression, which increases the risk of early relapse. Depression can cause relapse to occur 3 times faster in individuals with AUD who experience depressive symptoms at discharge. No treatments have been approved for individuals with both AUD and depression. Psilocybin, a psychedelic, shows...

Modeled Long-Term Effects of Psilocybin on Dynamic Activity and Effective Connectivity of Fronto-Striatal-Thalamic Circuits

ABSTRACT Psilocybin has been shown to induce fast and sustained symptoms improvements across various psychiatric conditions, yet its long-term mechanisms of action are not fully understood. Initial evidence suggests that longitudinal functional and structural brain changes implicate fronto-striatal-thalamic (FST) circuitry, a broad system involved in goal-di...

Psilocybin shows mixed results for patients with treatment-resistant depression

Patients with treatment-resistant depression who received psilocybin-assisted psychotherapy showed clinically meaningful improvement in depressive symptoms relative to placebo, a Phase 2b trial has found. However, the study did not show a significant effect on the primary outcome of treatment response 6 weeks after the first of two doses of psilocybin. Study...

Blinding Integrity in Psychedelic Randomized Clinical Trials: A Systematic Review.

Psychedelic drugs possess acute psychoactive effects that can compromise blinding integrity in randomized clinical trials (RCTs). Functional unblinding, when participants or raters correctly identify treatment allocation based on subjective effects, may bias outcomes through expectancy effects, challenging the validity of efficacy estimates and regulatory ac...

MFCC-DFT mapping of ligand recognition at the 5-HT receptor: energetic analysis of the interactions between serotonin, psychedelics, and antipsychotics.

Mental disorders represent a major global health problem, with depression being one of the most prevalent and disabling conditions worldwide. Growing evidence suggests that the serotonergic system, particularly the 5-HT receptor, plays an important role in modulating mood and cognitive processes, constituting a key pharmacological target for several psychoac...

Chemistry/structural biology of psychedelic drugs and their receptor(s).

This brief review highlights some of the structure-activity relationships of classic serotonergic psychedelics. In particular, we discuss structural features of three chemotypes: phenethylamines, ergolines and certain tryptamines, which possess psychedelic activity in humans. Where they are known, we point out the underlying molecular mechanisms utilized by ...

Neuropsychopharmacology of hallucinogenic and non-hallucinogenic 5-HT receptor agonists.

Psychedelic drugs such as LSD and psilocin were once relegated to the fringes of medical research because of their association with counterculture movements and a perceived concern about harm through recreational use, and their consequent legal prohibition in the early 1970s. However, these drugs are now experiencing a renaissance in the field of psychiatry ...

Psychedelics, entactogens and psychoplastogens for depression and related disorders.

Currently, the most actively investigated rapidly acting antidepressants, anxiolytics and/or anti PTSD agents, include psychedelics e.g. psilocybin, LSD, N,N-dimethyltryptamine, ayahuasca; non-hallucinogenic entactogens, e.g. MDMA; psychoplastogens which rapidly promote neuroplasticity, e.g. ibogaine, ketamine and esketamine; and other atypicals e.g. dextrom...

Evidence that 5-HT receptor signalling efficacy and not biased agonism differentiates serotonergic psychedelic from non-psychedelic drugs.

Serotonergic psychedelic drugs are under investigation as therapies for various psychiatric disorders, including major depression. Although serotonergic psychedelic drugs are 5-HT receptor agonists, some such agonists are not psychedelic, potentially due to differences in 5-HT receptor ligand bias or signalling efficacy. Here, we investigated 5-HT receptor s...
