Psilocin mediates long-term synaptic depression in the prelimbic cortex through 5-HT2A receptor-independent mechanisms

Neuropharmacology January 21, 2026 Ana Domi, Erika Lucente, Davide Cadeddu et al. 1 citation

Psilocybin is a naturally occurring psychedelic compound with potential antidepressant effects. Although it has long been used by humans, primarily for recreational purposes, the molecular mechanisms underlying its actions remain incompletely understood. Here, we examined the acute effects of psilocin, the active metabolite of psilocybin, on excitatory neurotransmission in the prefrontal cortex...

Effects of psilocybin and chronic mild stress on microglial activation in rat spinal cord: an ex vivo analysis

Pharmacological Reports January 20, 2026 Piotr Olejnik, Katarzyna Kamińska, Krystyna Gołembiowska et al.

INTRODUCTION: Psilocybin, a classic serotonergic psychedelic, has antidepressant, anxiolytic, anti-inflammatory, and analgesic properties. However, the immunomodulatory effects of psilocybin within the central nervous system, particularly on microglial activation, remain poorly understood. Therefore, this study aimed to investigate the effects of psilocybin on microglial activation markers and...

Insights into psilocybin use among people with bipolar disorder: A thematic analysis of Reddit posts

Journal of Affective Disorders January 20, 2026 Laura Mills, Susan L. Rossell, Sean Carruthers

Psilocybin has been reported to decrease depression symptoms among individuals with bipolar disorder (BD), but has also been associated with reports of mania, psychosis and increased depression. With increasing recreational use of psilocybin, and the potential for psilocybin to be used as a treatment for depression, a better understanding of the risks and benefits of this psychedelic among...

Group Retreat Psilocybin Therapy for People with Metastatic Cancer with Symptoms of Anxiety and Depression: Safety and Efficacy Outcomes of a Phase 1/2 Study

Psychedelic Medicine January 18, 2026 Anthony L. Back, Bonnie A. Mcgregor, Leslie Lazar Thorn et al. 1 citation

Background: Psilocybin is a promising therapy for cancer-related distress, but existing individual treatment models are resource intensive. In this study, we designed and tested a group model of psilocybin therapy for people with metastatic cancer and cancer-related anxiety and depression. Method: Eligibility criteria included metastatic cancer, moderate-to-severe symptoms of anxiety or...

Bridging the reporting gap: Application of the ReSPCT guidelines in psilocybin clinical trial protocols.

European Neuropsychopharmacology January 16, 2026 Damian Swieczkowski, Aleksander Kwaśny, Krzysztof Sadko et al. 1 citation

Psilocybin-assisted therapies are increasingly studied for Major Depressive Disorder (MDD) and Treatment-Resistant Depression (TRD), and methodological rigor requires both pharmacological evaluation and consistent reporting of non-pharmacological variables that influence therapeutic outcomes. To address this need, the ReSPCT (Reporting of Setting in Psychedelic Clinical Trials) guidelines were...

Psilocybin rapidly, but not immediately, reverses reward learning deficits in a durable manner in an inflammatory rat model of depressive symptoms

bioRxiv (Cold Spring Harbor Laboratory) January 15, 2026 Justyna K. Hinchcliffe, Christopher W. Thomas, Gary Gilmour et al. preprint

Abstract The serotonergic psychedelic, psilocybin, shows potential for rapid and sustained antidepressant effects but the underlying mechanisms remain unknown. Using a chronic interferon-alpha–induced rat model of depression, we show acute psilocybin (0.3 mg/kg) reverses impaired reward-induced biases within 24hrs, with effects enduring for at least 7 days. This suggests psilocybin can restore...

Psilocybin for Treatment-Resistant OCD: A Randomized Controlled Trial

January 15, 2026 Benjamin Kelmendi, Thomas G. Adams, Terence H. W. Ching et al. preprint

Background: Obsessive-compulsive disorder (OCD) affects 2-3% of the population worldwide. 40-60% of patients do not respond to first-line interventions. We evaluated the efficacy and safety of a single dose of psilocybin in patients with treatment-resistant OCD.Methods: In this phase 2, randomized, double-blind trial, we randomly assigned 28 adults with treatment-resistant OCD to receive a...

The Psychological Support Model in Psilocybin Research: Psychotherapy in Disguise?

Psychiatric Research and Clinical Practice January 14, 2026 Celia Faye Jacobsen, Dea Siggaard Stenbæk, Stig Poulsen et al. 3 citations

A key distinction among clinical trials on psilocybin treatments, for example, those targeting depression, has been whether the psilocybin dosing session is combined with bona fide psychotherapy or with what is referred to as “psychological support” (1-3). The most developed model of psychological support is the Compass Psychological Support Model (CPSM; 1). Kirlić and colleagues specifically...

Intentions, Spirituality, Set, and Setting Are Associated with Mystical Experiences in Psilocybin-Assisted Therapy

Psychedelic Medicine January 12, 2026 Kelsey T. Laird, Prabha Siddarth, Ashley Ramos et al.

Objective: Emerging evidence suggests that mystical experiences mediate the therapeutic effects of psychedelic-assisted therapy. The current study examines associations between mystical experiences and components of “set” (positive mindset, participant intentions, and spirituality) and “setting” (perceived positivity of the dosing environment) in the context of psilocybin-assisted therapy for...
