Abstract High-grade gliomas are the most aggressive form of brain tumors, and neuronal activity has emerged as a driver of glioma pathophysiology. Activity-dependent glioma growth results from paracrine factor signaling and bona fide neuron-to-glioma synapses that integrate glioma cells into brain-wide neuronal circuits. Here, we report how glioma cells inte...
After many years of stigma and neglect, there is a resurgence of interest in the therapeutic use of psychedelic drugs. Anecdotal and evidence-based reports indicate psychedelics as a possible treatment for depression, anxiety, PTSD, substance abuse, and other disorders resistant to conventional medical interventions. The available data, however, are limited ...
Chronic pain affects millions of people and remains one of the greatest clinical challenges due to limited response to conventional therapies. Psilocybin, a psychedelic found in mushrooms of the Psilocybe genus, has sparked interest due to its potential to modulate serotonergic receptors and promote neuroplasticity, suggesting analgesic and psychotherapeutic...
Psilocybin is a serotonergic psychedelic with growing evidence for efficacy in mood disorders, and its therapeutic potential in obsessive-compulsive disorder (OCD) and related conditions is increasingly recognised but remains understudied. We systematically evaluated clinical and preclinical evidence on psilocybin's effects on obsessive and compulsive behavi...
A meta-analysis comprising 17 randomized trials has found that rates of control group improvement in depression studies were lower in psilocybin trials than in studies of esketamine or a selective serotonin reuptake inhibitor (SSRI). The results suggest that psilocybin's overall efficacy in the treatment of depression might be overestimated.
Prior research has determined that music plays a central role in psychedelic assisted therapy (PAT). While there is a general consensus of the importance of music during PAT, there are only three empirical studies published to date that directly investigate which type of music might best support PAT. Importantly, no review to date has critically analyzed the...
A crystalline cocrystal of psilocin and psilocybin enhances exposure, neuroplasticity biomarkers, and functional activity, while adjunctive atypical antipsychotics modulate serotonergic signaling to mitigate 5-HT2B-linked safety concerns. Together, these inventions advance formulation, mechanistic selectivity, and translational biomarkersoffering a chemistr...
Psilocybin is found in a family of mushrooms commonly known as Psilocybe. We aimed to study the antinociceptive efficacy of psilocybin using formalin-induced noxious stimuli, a model that comprises both acute and persistent pain in rats. Adult male Sprague-Dawley rats were used. Psilocybin (0.1, 0.3, and 1 mg/kg, IP) or vehicle was administered, and 6 h late...
BACKGROUND: In recent years, there has been a resurgence of scientific interest in psychedelics, including psilocybin, for their potential in treating neuropsychiatric disorders. However, the reward-related effects of psilocybin and its impact on behavior remain underexplored. AIMS: We aimed to evaluate the potential rewarding effects of high doses of psiloc...
Serotonergic psychedelics have shown promise in clinical trials for treating an array of mental health disorders, including depression, anxiety, and post-traumatic stress disorder. Despite these findings, our understanding of how these drugs mechanistically exert their therapeutic effects remains incomplete. While researchers have regularly employed rodent p...
OBJECTIVE: Due to the boom in the use of certain psychedelics in different neuropsychiatric conditions, the objective was to synthesize the available information on the use of psilocybin (a psychedelic) in the population with autism spectrum disorder (ASD; a developmental neuropsychiatric condition). METHODS: Scoping review. Question framework: Population: p...
Background: Depressive disorders are a major global health challenge, with many individuals unresponsive to existing treatments. Novel psychedelic therapies show promise but require further research. Objectives: This study aimed to evaluate the feasibility, safety and effectiveness of psilocybin with psychotherapeutic support for treatment-resistant depressi...
Background: Post-traumatic stress disorder (PTSD) is a debilitating condition for which there are few efficacious treatments. Psilocybin is being studied for use in treatment-resistant depression but has not yet been investigated in PTSD. Aims: The trial’s primary outcome was to investigate the safety and tolerability of single-dose psilocybin in participant...
BACKGROUND AND AIMS: Drug discrimination procedures have made important contributions to the pre-clinical investigation of psychedelic drugs, such as psilocybin, lysergic acid diethylamide (LSD), N,N-dimethyltryptamine (DMT) and 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT). One of the most important being to highlight the critical role of central 5-HT2A rece...
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...
Use of selective serotonin reuptake inhibitor (SSRI) antidepressants has been associated with reduced intensity of emotional experience. Conversely, some research has shown that use of psilocybin in patients with depression leads to an increase in responsiveness to emotional face stimuli, suggesting that the psychedelic generates a transient elevation in moo...
