Newest firstBackground and hypothesis A sex difference in the clinical presentation of schizophrenia is well known. Males have on average an earlier symptom onset, worse functional capacity, and more negative symptoms. Studies on the neurobiological correlates of psychosis show that brain endocannabinoid system (ECS) is dysregulated in male patients with first-episode psychosis (FEP). We now evaluated whether the brain ECS is…
Open article record in new tab ↗Current tools for spatial omics analysis often face challenges in performing integrated transcriptomics and metabolomics analysis, in-depth biological interpretation, and user-friendly operation. To address this, we developed SMIntegration, the first web-based graphical platform designed specifically for integrated spatial metabolomics and transcriptomics analysis. Built with R/Shiny and deployed using Docker cont…
Comorbid substance use disorders (SUDs) are common but difficult to study due to the complex, interacting and overlapping mechanisms through which they affect brain networks. Many datasets collected to investigate a specific SUD include participants with comorbid SUDs. Although most studies treat comorbid SUDs as covariates of no interest, these covariates also contain untapped information. This is particularly re…
Open article record in new tab ↗Background Cannabis use among young adults has reached the highest levels ever recorded. Evidence indicates that acute Δ9-tetrahydrocannabinol (THC) disrupts brain connectivity. Few studies have examined this on a whole-brain level. We examined the effects of a single moderate dose of THC on resting-state functional brain networks among young adult cannabis users. Methods In a within-subject, double-blind, randomi…
Adaptive emotion regulation is essential for mental health. Reappraisal and acceptance are effective yet cognitively distinct emotion regulation strategies. A key unanswered question is whether their neural implementations are supported by common overarching or distinct neurofunctional processes, especially under dynamic, naturalistic conditions that mirror real-life scenarios. Here, we combined naturalistic fMRI…
Open article record in new tab ↗Opioid use disorder (OUD) remains a major public health crisis, underscoring the urgent need for safer and more effective treatments. Cannabinoid CB2 receptor (CB2R) agonists show therapeutic promise for neuropsychiatric disorders and pain, with minimal psychoactive effects by themselves, but their potential in treating OUD is not well defined. Here, we report that MRI-2594, a novel, highly selective CB2R agonist,…
Aims To describe differences in the expression of genes encoding cannabinoid receptors (CNR1, CNR2), the associated receptor GRP55 and the enzymes fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MGLL) between individuals with alcohol use disorder (AUD) and controls in key mesocorticolimbic brain regions. Design Case-control, observational postmortem study comparing gene expression in brain tissue fr…
BACKGROUND: Neuropathic pain (NP) is a chronic and debilitating condition that remains difficult to treat, with opioids like morphine often leading to tolerance and reduced efficacy over time. Cannabidiol (CBD) has emerged as a potential therapeutic for NP even in morphine tolerance conditions; however, its effects on nociceptive modulation and neurotransmitter metabolism in morphine-tolerant NP models remain poor…
BackgroundCannabidiol (CBD) has attracted renewed scientific attention for its therapeutic potential in human metabolism. However, the metabolic effects of CBD treatment remain incompletely understood.MethodsThis study investigated tissue-specific metabolic alterations in the brain, liver, and kidneys of Kramnik mice after 2 weeks of daily CBD treatment using an untargeted proton magnetic resonance (1H-NMR) metabo…
Open article record in new tab ↗Cannabis use is highly prevalent in individuals with psychosis, raising concerns about its influence on brain function. Electroencephalography (EEG) studies have identified alterations in brain activity in psychosis, including changes in spectral entropy (SE) modulation and connectivity strength (CS). However, the degree to which cannabis use contributes to these alterations remains unclear. This study investigate…
Introduction Prenatal substance exposure is an increasing problem that has been linked to multiple neurodevelopmental impairments and alterations to brain functional connectivity. Methods Behavioral scores and functional network correlation data were obtained from the Adolescent Brain Cognitive DevelopmentSM (ABCD) Study. First, behavioral scores based on the child behavioral checklist were tested for associations…
Open article record in new tab ↗Co-administration of cannabinoids and opioids has been shown to enhance analgesic effects. However, the underlying mechanisms remain unclear. One hypothesis suggests that cannabinoid CB1 receptors (CB1R) and mu-opioid receptors (MOR) interact at the cell membrane or intracellular signaling level. This study aimed to test this hypothesis by examining CB1R-MOR colocalization and assessing whether the deletion of one…
Open article record in new tab ↗PURPOSE OF REVIEW: This review evaluates structural neuroimaging research on substance-related psychosis to determine if these conditions share common neurobiological pathways with primary psychotic disorders, such as schizophrenia, or exhibit unique signatures. RECENT FINDINGS: Research indicates that methamphetamine, cannabis, and cocaine induce significant structural changes, including cortical thinning and gre…
Open article record in new tab ↗Background Cannabis constituents, including Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD), show distinct pharmacological profiles with therapeutic relevance for neurological and psychiatric conditions. THC exerts euphoric effects primarily via CB1 receptor activation, while CBD displays non-euphoric properties affecting various pathways. Aims This study evaluated the effects of THC, CBD, and their combinatio…
Multiple sclerosis (MS) is a chronic inflammatory neurodegenerative disorder that typically affects young adults and is primarily characterized by demyelinating lesions in the central nervous system (CNS). According to the Revised McDonald Criteria, the clinical diagnosis of MS can be established based on a combination of clinical observations, the presence of focal lesions in at least two distinct CNS areas on ma…
Gut-brain signaling influences alcohol consumption and addiction behaviors. We found that selectively deleting cannabinoid receptor 1 (CB1R) from advillin+ peripheral sensory neurons eliminates the inhibitory effect of the peripheral CB1R antagonist JD5037 on voluntary ethanol intake (VEI). Similar results were seen in mice with CB1R deletion in Phox2b+ nodose ganglia (NGA), but not in Wnt+ dorsal root ganglia. Th…
Cannabigerol (CBG) is a nonintoxicating phytocannabinoid gaining popularity as a self-medication for anxiety and other conditions; however, its pharmacological properties remain poorly defined. Here, we report the development of a rapid and sensitive liquid chromatography-tandem mass spectrometry method for quantifying CBG and its primary oxidative metabolite, cyclo-CBG. This platform enabled the characterization…
Epilepsy is a progressive network disorder in which recurrent seizures drive maladaptive neurodevelopmental remodeling, cognitive decline, and pharmacoresistance, particularly in developmental epileptic encephalopathies. Cannabidiol (CBD) has emerged as an evidence-based adjunctive therapy for selected childhood-onset epilepsies; however, its broader clinical utility remains limited by heterogeneous responsiveness…
Background: Emerging evidence indicates that epilepsy extends beyond the brain, involving systemic metabolic, immune, and microbiome perturbations that shape neuronal excitability and treatment response. Canine idiopathic epilepsy (CE) offers a naturally occurring model with strong electrophysiological, pharmacological, and clinical homology to human epilepsies. Methods: This scoping review was conducted according…
Open article record in new tab ↗Background and PurposeQuantitative relaxometry on the integrated MRI / linear accelerator (MR-Linac) at high isotropic resolution is currently limited due to prohibitively long scan times and limited field-of-views. Therefore, the purpose of this study was to assess the technical feasibility of the 3D-QALAS technique on the 1.5T MR-Linac which has the ability to acquire whole-brain 1 mm isotropic quantitative T1,…
