In recent decades, psilocybin has gained attention as a potential drug for several mental disorders. Clinical and preclinical studies have provided evidence that psilocybin can be used as a fast-acting antidepressant. However, the exact mechanisms of action of psilocybin have not been clearly defined. Data show that psilocybin as an agonist of 5-HT2A recepto...
ABSTRACT Background and Purpose Serotonergic psychedelic drugs are under renewed investigation for the potential treatment of several psychiatric disorders. While all serotonergic psychedelics have 5-HT2A receptor activity, the explanation for why some 5-HT2A receptor agonists are not psychedelic is unknown. To address this question, we investigated the 5-HT...
e22518 Background: Classic psychedelics (Peyote, Psilocybin, Mescaline, and LSD) are re-emerging in the oncology toolbox. Peyote is the oldest known psychedelic, yet underexplored in clinical research. Preclinical studies suggest its extract stimulates lymphocyte proliferation, kills tumor cells, and may regulate sleep. This study aims to estimate the preval...
BACKGROUND: Psilocybin offers new hope for treating mood disorders due to its rapid and sustained antidepressant effects, as standard medications require weeks or months to exert their effects. However, the mechanisms underlying this action of psilocybin have not been identified. AIMS: To investigate whether psilocybin has rapid and sustained antidepressant-...
Psychedelics like LSD (Lysergic acid diethylamide) and psilocybin are known to modulate perceptual modalities due to the activation of mostly serotonin receptors in specific cortical (e.g., visual cortex) and subcortical (e.g., thalamus) regions of the brain. In the visual domain, these psychedelic modulations often result in peculiar disturbances of viewed ...

Serotonin emerges as a pivotal factor influencing the growth and functionality of β-cells. Psilocybin, a natural compound derived from mushrooms of the Psilocybe genus, exerts agonistic effects on the serotonin 5-HT2A and 5-HT2B receptors, thereby mimicking serotonin’s behavior. This study investigates the potential impacts of psilocybin on β-cell viability,...
Psilocybin, an innate compound produced by mushrooms belonging to the Psilocybe genus, is primarily known for its agonistic effects on the serotonin 5-HT2A receptor. This receptor’s functioning is involved in many neurological processes. In the context of this research, our primary aim was to comprehensively investigate the influence of psilocybin as a serot...
This study is to find out about whether two sessions of psilocybin-assisted psychotherapy are safe and will help people who are anxious as a result of having stage IV melanoma and will involve two sessions of psychotherapy combined with either 4 or 25 mg psilocybin. The study will measure anxiety, depression, quality of life and spirituality before and after...
ABSTRACT Psychedelic drugs like lysergic acid diethylamide (LSD) and psilocybin have emerged as potentially transformative therapeutics for many neuropsychiatric diseases, including depression, anxiety, post-traumatic stress disorder, migraine, and cluster headaches. LSD and psilocybin exert their psychedelic effects via activation of the 5-hydroxytryptamine...
ABSTRACT Intracellular calcium (Ca 2+ ) is ubiquitous to cell signaling across all biology. While existing fluorescent sensors and reporters can detect activated cells with elevated Ca 2+ levels, these approaches require implants to deliver light to deep tissue, precluding their noninvasive use in freely-behaving animals. Here we engineered an enzyme-catalyz...
Intestinal inflammation and dysbiosis can lead to inflammatory bowel diseases (IBD) and systemic inflammation, affecting multiple organs. Developing novel anti-inflammatory therapeutics is crucial for preventing IBD progression. Serotonin receptor type 2A (5-HT2A) ligands, including psilocybin (Psi), 4-Acetoxy-N,N-dimethyltryptamine (4-AcO-DMT), and ketanser...
Abstract Psilocybin is the psychoactive substance contained in the psilocybe(hallucinogenic) mushroom, which has received considerable attention among the scientific community in recent years. Human studies have demonstrated that even a single-dose of psilocybin can improve debilitating physical and psychological symptoms with durable long-term effects. >136...
Psilocybin-containing mushrooms, commonly known as magic mushrooms have antidepressant effect, however, their safety in cardiovascular diseases such as heart failure is not fully known and needs to be investigated. Cardiac hypertrophy is an independent risk factor for heart failure morbidity and mortality. Angiotensin II (Ang-II) plays a major role in the pa...
BACKGROUND: Posttraumatic stress disorder (PTSD) and depression are highly comorbid. Psilocybin exerts substantial therapeutic effects on depression by promoting neuroplasticity. Fear extinction is a key process in the mechanism of first-line exposure-based therapies for PTSD. We hypothesized that psilocybin would facilitate fear extinction by promoting hipp...
Depression is a major public health concern. Unfortunately, the present antidepressants often are insufficiently effective, whilst the discovery of more effective antidepressants has been extremely sluggish. The objective of this review was to combine the literature on depression with the pharmacology of antidepressant compounds, in order to formulate a conc...
Research on classical psychedelics (psilocybin, LSD and DMT) and entactogen, MDMA, has produced a renaissance in the search for more effective drugs to treat psychiatric, neurological and various peripheral disorders. Psychedelics and entactogens act though interaction with 5-HT2A and other serotonergic receptors and/or monoamine reuptake transporters. 5-HT,...
There is much excitement surrounding recent research of promising, mechanistically novel psychotherapeutics - psychedelic, anesthetic, and dissociative agents - as they have demonstrated surprising efficacy in treating central nervous system (CNS) disorders, such as mood disorders and addiction. However, the mechanisms by which these drugs provide such profo...
4-Phosphoryloxy-N,N-dimethyltryptamine (psilocybin) is a naturally occurring tertiary amine found in many mushroom species. Psilocybin is a prodrug for 4-hydroxy-N,N-dimethyltryptamine (psilocin), which induces psychedelic effects via agonist activity at the serotonin (5-HT) 2A receptor (5-HT2A). Several other 4-position ring-substituted tryptamines are pres...
Chinese Cordyceps is a valuable source of natural products with various therapeutic effects. It is rich in various active components, of which adenosine, cordycepin and polysaccharides have been confirmed with significant immunomodulatory and antitumor functions. However, the underlying antitumor mechanism remains poorly understood. In this review, we summar...
