The application of esketamine in cancer-related depressive states: attention from mechanisms to clinical translation

Frontiers in Psychiatry July 30, 2026 Liangju Chen, Yonghua Chen, Ying Zhao et al.

Objectives: This article reviews the clinical status and treatment challenges of cancer-related depressive states, clarifies the mechanism of action of esketamine-a novel rapid-acting antidepressant-compares its efficacy with traditional drugs, evaluates safety and tolerability, and summarizes clinical evidence to support clinical practice and research. Methods: By searching databases such as...

Long- term administration of low doses of psilocybin causes epigenetic changes in the rat medial prefrontal cortex

Psychopharmacology July 28, 2026 Agnieszka Wawrzczak-Bargieła, Małgorzata Jelonek-Kozioł, Weronika Kumorek et al.

RATIONALE: Psilocybin (PSI) microdosing, defined as a repeated administration of sub-perceptual doses, has gained increasing attention as a potential therapeutic strategy for affective and anxiety disorders. However, some molecular mechanisms, particularly regarding epigenetic regulation in the medial prefrontal cortex (mPFC), remain poorly understood. OBJECTIVES: Therefore, the present study...

Neuroscientific foundations of meditation: an advanced analysis of neurochemical systems, neural network dynamics, and central functional plasticity

STUDIES IN HEALTH SCIENCES July 27, 2026 Kleber Mirallia de Oliveira, Yohana Heloise Mirallia, A. C. Moreira et al.

Background: The practice of meditation and mindfulness techniques has garnered significant interest within the international scientific community due to its potential to induce functional and structural plasticity in the Central Nervous System (CNS). This advanced narrative review aims to analyze, refine, and systematize the neuroscientific foundations of meditation, correlating ultrastructural...

Age as a Moderator of Psychoactive-Assisted Psychotherapies Outcomes: A Systematic Literature Review and Meta-Analysis

July 27, 2026 Asher Wenig, David B Newman preprint

This project will use a PRISMA-guided systematic review and meta-analysis to examine whether age moderates anxiety and depression outcomes following psychoactive-assisted treatments. In this review, psychoactive-assisted treatments are defined as clinically structured treatments involving classic serotonergic psychedelics, MDMA, ketamine, or esketamine. The term is intentionally broader than...

Classic Psychedelics for Treating Chronic Pain: Mechanism and Clinical Translation

Molecules July 27, 2026 Hongyu Chen, Bowen Ke, Ruotian Jiang

Chronic pain is a complex disorder of central nervous system maladaptation, perpetuated not only by ascending nociceptive transmission but also by entrenched prior expectations. Conventional analgesics typically fail to reverse this cognitive rigidity and the ensuing pathological cycles. Classic psychedelics, however, are emerging as a promising avenue to help address this therapeutic impasse....

Ketamine preserves perineuronal nets in chronic stressed mice brain through the inhibition of microglia activation

IBRO Neuroscience Reports July 26, 2026 Jingwen Yang, Ting Huang, Meng Wang et al.

Background Deeper understanding of ketamine’s mechanism of action would contribute to the discovery of novel therapeutic targets with fast-onset actions. To gain insight on the mechanism underlying the antidepressant-like effects of ketamine, we focused on perineuronal nets (PNNs), an extracellular matrix structure that surrounds fast-spiking parvalbumin-positive interneurons and regulates...

MDMA as an early post-trauma intervention in a translational animal model of PTSD.

Progress in Neuro-Psychopharmacology and Biological Psychiatry July 24, 2026 Omer Baruch, Nadav Reiss, Doron Todder et al.

Post-traumatic stress disorder (PTSD) remains difficult to prevent after trauma, highlighting the need for early interventions that reduce the risk of chronic symptom development. This controlled study investigated the preventive potential of 3,4-methylenedioxymethamphetamine (MDMA) in a validated rat model of PTSD induced by predator scent stress (PSS). Adult male Sprague-Dawley rats (N = 175)...

Psychedelics and Reward Processing: Before and After the 1970 Controlled Substances Act

Psychedelic Medicine July 24, 2026 Matthew C. Company, Dylan J. Lifshitz, M. Farris Sawaya et al.

This narrative review traces how the scientific understanding of psychedelics has intersected with “reward processing” from before the Controlled Substances Act (CSA) era to the present, emphasizing how cultural and regulatory climates shaped what was viewed as an acceptable research question. Reward processing is treated as a family of partially overlapping phenomena: (1) reward-linked...

5-MeO-DMT induces NEIL3-independent acute cell proliferation in the adult dentate gyrus

Molecular Brain July 24, 2026 Rafael V Lima Da Cruz, Richardson N. Leão, Thiago C. Moulin

Abstract Adult dentate gyrus neurogenesis and cell proliferation are regulated by multiple physiological inputs, including experience-dependent signals that have been linked to the DNA glycosylase NEIL3. Whether NEIL3 also gates psychedelic-induced proliferation is unknown. Here we tested the effect of a single dose of 5-methoxy-N, N-dimethyltryptamine (5-MeO-DMT), a serotonergic agonist with...
