Are we hallucinating or can psychedelic drugs modulate the immune system to control inflammation?

Psychedelic drugs that activate 5-HT receptors have been long used for cultural, medicinal and recreational purposes. Interest in psychedelics for treating psychiatric disorders has resurged recently and is well documented; less well recognised are their anti-inflammatory properties. Growing evidence now demonstrates that psychedelics modulate immune respons...

Psychedelics as pharmacotherapeutics for substance use disorders: A scoping review on clinical trials and perspectives on underlying neurobiology.

Psychedelics have garnered great attention in recent years as treatments for major depressive disorder (MDD) and treatment-resistant depression because of their ability to alter consciousness and afflicted cognitive processes with lasting effects. We aimed to characterise how psychedelics are currently being investigated to treat substance use disorders (SUD...

Psilocybin improves novel object recognition in a rat model of Fragile X Syndrome through the modulation of the BDNF/TrkB signaling pathway.

Fragile X Syndrome (FXS) is the most common inherited intellectual disability and a leading monogenic cause of autism spectrum disorder (ASD). As a synaptic disorder, FXS involves the loss of Fragile X messenger ribonucleoprotein 1 (FMRP), leading to abnormal dendrite development and immature dendritic spines. Serotonergic signaling, essential for neuronal d...

Psychedelics as a potential treatment for borderline personality disorder: A narrative review.

Borderline personality disorder (BPD) is a serious mental illness with high rates of morbidity and stigma; however, successful remission is frequently limited by a paucity of accessible treatment options. In an era of growing interest in psychedelics as novel psychiatric treatment modalities, patients with BPD are often excluded from research due to perceive...

Acute dose-dependent effects of 4-bromo-2,5-dimethoxyphenethylamine (2C-B) compared with 3,4-methylenedioxymethamphetamine (MDMA) and psilocybin in a double-blind, placebo-controlled study in healthy participants.

Based on its in vitro profile and preliminary evidence, 4-bromo-2,5-dimethoxyphenethylamine (2C-B) may have psychoactive properties that are similar to 3,4-methylenedioxymethamphetamine (MDMA) and psilocybin, which are investigated for the treatment of posttraumatic stress disorder and depressive disorders. We compared acute effects of 2C-B (10, 20, and 30 m...

A Multicenter Phase 1 Safety and Tolerability Trial of Psilocybin in Healthy Older Adults

This study plans to learn more about the safety and tolerability of psychedelic administration (psilocybin) in healthy older adults ages 65-85. The purpose of this study is to learn whether psilocybin, a psychedelic compound, can be given safely to older adults. We want to understand how psilocybin affects the body and mind, including blood pressure, heart r...

Background Anorexia nervosa (AN) is a severe psychiatric disorder with high morbidity, mortality, and relapse rates, most commonly emerging during adolescence. Despite specialized psychological and nutritional treatments, outcomes remain suboptimal, with high rates of relapse and chronicity. Psilocybin has been investigated with preliminary efficacy in other...

Chronic psilocin microdosing produces limited behavioral effects and does not enhance neurogenesis in rats.

Psilocin (4-hydroxy-N, N-dimethyltryptamine) is a substituted tryptamine alkaloid and a nonselective serotonergic agonist acting predominantly at 5-HT2A/C receptors, with substantial binding to 5-HT1A and 5-HT2B receptors. Microdosing is the practice of taking a very small, sub-perceptual dose, typically 5% to 10% of a full recreational dose, to improve mood...

Chemical ecology and convergent evolution of natural hallucinogens: From ecological defense to conserved neural targets.

Natural hallucinogenic compounds have arisen independently across plants, fungi, and animals, evolving into a diverse chemical arsenal that includes phenethylamines, indolealkylamines, and terpenoid scaffolds. Beyond clinical and cultural frameworks, their ecological origins and evolutionary trajectories may help explain why such potent modulators of percept...

Psychedelics in treatment-resistant depression: a comprehensive review of mechanisms, clinical evidence, and recommendations.

Major depressive disorder (MDD) is a heterogeneous, debilitating disorder. A distinct subgroup within the MDD spectrum is identified to have treatment-resistant depression (TRD). There is an impetus to find alternative treatments for TRD to reduce disease burden and improve quality of life. Psychedelics have been used in the treatment of various psychiatric ...

Psilocybin reduces fear memory and restores neuroplasticity in the hippocampus and medial prefrontal cortex

Background: Posttraumatic stress disorder (PTSD) and major depressive disorder are often comorbid in humans. Psilocybin reportedly has beneficial therapeutic effects on depression, possibly by promoting neuroplasticity. PTSD is associated with the dysregulation of neuroplasticity in the hippocampus and medial prefrontal cortex (mPFC). We hypothesized that ps...
