The psychedelic psilocybin is being investigated for the treatment of depression and anxiety. Unclear is whether antidepressant treatments interact with psilocybin. The present study used a double-blind, placebo-controlled, crossover design with two experimental test sessions to investigate the response to psilocybin (25 mg) in healthy subjects after pretrea...
Therapeutic deficiencies with monoaminergic antidepressants invites the need to identify and develop novel rapid-acting antidepressants. Hitherto, ketamine and esketamine are identified as safe, well-tolerated rapid-acting antidepressants in adults with treatment-resistant depression, and also mitigate measures of suicidality. Psilocybin is a naturally occur...
The Psilocybe genus is well known for the synthesis of valuable psychoactive compounds such as Psilocybin, Psilocin, Baeocystin and Aeruginascin. The ubiquity of Psilocybin synthesis in Psilocybe has been attributed to a horizontal gene transfer mechanism of a ~20Kb gene cassette. A recently published highly contiguous reference genome derived from long read...
Metabolic regulation strategies have been developed to redirect metabolic fluxes to production pathways. However, it is difficult to screen out target genes that, when repressed, improve yield without affecting cell growth. Here, we report a strategy using a quorum-sensing system to control small RNA transcription, allowing cell-density-dependent repression ...
In this manuscript, I reflect on how Critical Indigenous theory offers white historians like myself powerful conceptual tools to combat the underlying, historically-rooted colonial assumptions prevalent in their work, specifically within the subfield of psychedelic history. Histories of compounds like lysergic acid diethylamide (LSD), psilocybin, ayahuasca, ...
Introduction: Psilocybin mushroom use is well documented in spiritual and religious ceremonies globally. This drug is now the most popular in Europe and the USA. Objective: The objective of this study is to explore the experiences and effects of psilocybin on patients with depression and anxiety. Method: A qualitative study was conducted interviewing ten par...
Hallucinogenic mushroom is a kind of toxic strain containing psychoactive tryptamine substances such as psilocybin, psilocin and ibotenic acid, etc. The mushrooms containing hallucinogenic components are various, widely distributed and lack of standard to define, which made a great challenge to identification. Traditional identification methods, such as morp...
Atheliales is a diverse order of crust-forming Basidiomycota fungi. Here, we report the draft genome of the "cuckoo fungus," Athelia (Fibularhizoctonia) sp. TMB strain TB5 (Atheliales), which forms termite-egg-mimicking sclerotia that termites tend. We further compare its repertoire of psilocybin gene homologs to homologs previously reported for Fibularhizoc...
Psilocybin is a classic serotonergic hallucinogen acting on the 5-HT2A receptor. It is used recreationally and in psychiatric research. Selective serotonin reuptake inhibitors (SSRIs) like escitalopram are first-line treatments for depression. They inhibit the serotonin transporter (SERT). This might cause a possible downregulation of postsynaptic 5-HT recep...
Background: Psilocybin is a serotonergic psychedelic found in “magic mushrooms” with a putative therapeutic potential for treatment-resistant depression, anxiety, obsessive-compulsive disorder, and addiction. In rodents, psilocybin acutely induces plasticity-related immediate early genes in cortical tissue; however, studies into the effects on subcortical re...

One among four people in the world are affected by mental or neurological illness at some point of their lives. An estimated number of 450 million people suffers from neurological disorders of one or the other type making mental disorders as the leading cause for disability across the globe. Under psychosis and depression maintenance therapy drug acting on D...
Hallucinogenic agents have been proposed as potent antidepressants; this includes the serotonin (5-HT) receptor 2A agonist psilocybin. In human subjects, psilocybin alters functional connectivity (FC) within the default-mode network (DMN), a constellation of inter-connected regions that is involved in self-reference and displays altered FC in depressive diso...
Psilocybin and its direct precursor baeocystin are indole alkaloids of psychotropic Psilocybe mushrooms. The pharmaceutical interest in psilocybin as a treatment option against depression and anxiety is currently being investigated in advanced clinical trials. Here, we report a biocatalytic route to synthesize 6-methylated psilocybin and baeocystin from 4-hy...
OBJECTIVE: Psilocybin is a serotonin receptor agonist with a therapeutic potential for treatment-resistant depression and other psychiatric illnesses. We investigated whether the administration of psilocybin had an antidepressant-like effect in a rat model of depression. METHODS: Using the Flinders Sensitive Line (FSL) rat model of depression, we assessed th...
Sleep paralysis is a state of involuntary immobility occurring at sleep onset or offset, often accompanied by uncanny "ghost-like" hallucinations and extreme fear reactions. I provide here a neuropharmacological account for these hallucinatory experiences by evoking the role of the serotonin 2A receptor (5-HT2AR). Research has shown that 5-HT2AR activation c...
