Introduction: Recently, there has been a significant increase in interest in the use of psychedelics for various psychiatric conditions. Psilocybin is receiving particular attention as a psychoactive substance with significant therapeutic potential. Recent research focuses on its possible benefits in the treatment of major depressive disorders (MDD) and anor...
Psilocybin-containing mushrooms have long been used for their psychoactive effects, but emerging evidence suggests that certain lignicolous (“wood-loving”) species may also induce a distinct toxidrome known as “wood-lover paralysis” (WLP). WLP is characterised by transient weakness following mushroom ingestion, but its aetiology and prevalence remain poorly ...
Psilocybin, a serotonergic compound that produces psychedelic effects primarily through activation of the 5-HT2A receptor, has shown promise in treating neuropsychiatric conditions, including obsessive-compulsive disorder (OCD). However, the effects of chronic psilocybin administration on gut function, microbiota, and behavioural phenotypes remain understudi...
Through its widespread reciprocal connections with the cerebral cortex, the claustrum is implicated in sleep and waking cortical network states. Yet, basic knowledge of neuromodulation in this structure is lacking. The claustrum is richly innervated by serotonergic fibers, expresses serotonin receptors, and is suggested to play a role in the ability of psilo...
Psilocybin, a compound found in Psilocybe mushrooms, is emerging as a promising treatment for neurodegenerative and psychiatric disorders, including major depressive disorder. Its potential therapeutic effects stem from promoting neuroprotection, neurogenesis, and neuroplasticity, key factors in brain health. Psilocybin could help combat mild neurodegenerati...
Depression, a common mental disorder, affects people at different stages of life.Classic antidepressant treatment is generally effective, however, it is prolonged.Nonetheless, numerous patients who undergo various classic antidepressant therapies still suffer from depression.Therefore, the search for novel medications is essential.In this review, we explore ...
Sleep paralysis (SP), an REM parasomnia, can be characterized as one of the symptoms of narcolepsy. The SP phenomenon involves regaining meta-consciousness by the dreamer during REM, when the physiological atonia of skeletal muscles is accompanied by visual and auditory hallucinations that are perceived as vivid and distressing nightmares. Sensory impression...
Major depressive disorder is a debilitating condition, with many patients unresponsive to conventional monoaminergic antidepressants. Rapid-acting antidepressants such as ketamine and psilocybin offer promising alternatives, relieving symptoms within hours. Ketamine, an NMDA receptor antagonist, and psilocybin, a serotonergic psychedelic primarily targeting ...
Research on psychedelic drugs, such as psilocybin, LSD or DMT, is a burgeoning field, with an increasing number of studies showing their promise in treatment of mental disorders as well as examining their mechanism of action. Determining their effect on the brain is crucial from clinical standpoint, but also offers highly promising avenues of advancement in ...
Depression and anxiety are disabling and high incidence mental disorders characterized by phenotypic heterogeneity. Currently available treatments show severe limitations. Thus, there is an urgent need for effective treatments in this population. In the search for novel rapid-acting antidepressants, the psychedelic psilocybin has emerged as a promising thera...

This is an interventional, parallel arm assignment treatment study in individuals with Major Depressive Disorder (MDD). Each individual will be treated with a single dose of pimavanserin or placebo plus a single dose of psilocybin. Evaluations will be taken before dosing and following dosing at several timepoints up to 5 weeks post-dosing. In this study, the...
Psychedelic compounds are emerging treatments for depression, capable of producing rapid and lasting symptom reduction after 1-2 administrations in the context of psychotherapy - a stark contrast to traditional antidepressants. Despite promising outcomes, the mechanisms underlying psychedelics' reported antidepressant effects remain poorly understood and are...
Abstract PcncAAAD is a calcium-activatable noncanonical aromatic L-amino acid decarboxylase (AAAD) featuring a unique appendage C-terminal domain (CTD) and two metal-binding sites. In this study, we establish an in silico RMSD-based evaluation model through molecular dynamics simulations, validated by in vitro enzyme assays, to decipher the enzyme’s calcium ...
Serotonin 5-HT2A receptors were one of the first serotonin receptors to be pharmacologically characterized. In mammals, they are expressed throughout the body in nearly every cell and tissue type, with the highest density in cortical layer V of the brain. They are involved in several aspects of normal physiological processes and behaviors and have been impli...
RationalePsilocybin is a potentially paradigm-shifting depression intervention. We conducted a systematic review and meta-analysis of psilocybin-for-depression randomized controlled trials (RCTs).ObjectivesSystematically assess harm reporting, risk of bias, action mechanism specification, and incremental therapeutic effect sizes in the psilocybin-for-depress...
IntroductionAlthough long known for their psychoactive effects, psychedelic drugs have only recently been investigated for medicinal use. Psilocybin has attracted the greatest interest with studies suggesting that it may be a useful agent in psychiatry and in palliative care.Areas coveredClinical trials that included psilocybin were searched in PubMed, Embas...
Chronic pain is a debilitating disease with current treatments lacking efficacy and safety, therefore discovery of new treatments is crucial. Initial studies suggest that psychedelics may be feasible for targeting pain, however clinical and preclinical controlled studies are necessary to further investigate that possibility. In this study we assessed the eff...
The recent renaissance in research on psychedelics such as psilocybin has highlighted their therapeutic potential including their lasting influences on brain function. Here we report that a single systemic administration of the serotonergic psychedelic psilocybin can durably promote social behaviour in the Cntnap2-knockout mouse model of autism. This effect ...
Brain aging (BA) processes are complex, often affect multiple systems, and frequently lead to cognitive decline and increased susceptibility to insults. BA appears to be a primary risk for the development of many prominent neurodegenerative pathologies. The US Census Bureau predicts that the aging population (65+) will represent a greater proportion of the U...
