Newest firstBackground and objective Lafora disease (LD) is a rare progressive disorder caused by mutations in the EPM2A or EPM2B genes, characterized by the accumulation of Lafora bodies, drug-resistant epilepsy, and cognitive decline. To investigate the early molecular mechanisms of LD, we studied electrophysiological changes in the dentate gyrus (DG) of the Epm2aR240X knock-in mouse model at various ages. Methods Electroph…
Open article record in new tab ↗This study aimed to investigate the protective effects of the CB2R ligand compound COCA (N-(3-chloro-2-methylphenyl)-5-(4-hydroxyphenyl)-1,2-oxazole-3-carboxamide) against bleomycin (BLM)-induced pulmonary fibrosis in mice. Compound COCA was identified via AI-driven virtual screening from the ChEMBL database. Forty male C57BL/6J mice were randomly divided into five groups: control, model (BLM), low-dose COCA, high…
Open article record in new tab ↗Binge drinking contributes to an increasing number of emergency department visits in the United States. Previous work demonstrated that an alcohol binge impairs cardiac performance and exerts complex hemodynamic effects through the activation of the endocannabinoid-mediated cannabinoid type 1 receptor (CB1R) signaling pathway. Anandamide (AEA), an endogenous CB1R agonist, is synthesized in response to various stre…
Glioblastoma (GBM) remains one of the most lethal brain tumors, with current therapies offering limited benefits and high relapse rates. This study presents the first preclinical evidence that pretreatment with inhaled cannabidiol (CBD) before tumor establishment can markedly inhibit GBM progression. We hypothesized that early CBD exposure could prime the immune and molecular landscape to resist tumor growth. C57B…
BACKGROUND: Inflammatory bowel diseases (IBD) are often associated with intestinal fibrosis. There is increased interest in new methods for managing intestinal fibrosis, among which the endocannabinoid system (ECS) is an interesting therapeutic target. The primary purpose of the study was to evaluate the effect of CB1/2 agonist, WIN 55,212-2 (WIN) on expression of fibrosis regulatory proteins: alpha smooth muscle…
Open article record in new tab ↗A hallmark of many psychiatric disorders is maladaptive and heightened fear responses to non-threatening stimuli. Adaptive defensive responses to threats involve transitions between passive behaviors, such as freezing, and active escape strategies, such as darting or fleeing. The endocannabinoid (eCB) system, particularly 2-arachidonoylglycerol (2-AG), plays a crucial role in modulating fear and stress responses.…
Open article record in new tab ↗Several studies show that neurosteroids currently play a significant role in autism spectrum disorders (ASD). However, the pathway of neurosteroid synthesis involved in ASD remains unclear. This study aimed to investigate the crosstalk between autism and neurosteroids, focusing on the mechanism of allopregnanolone production. We used the BTBR T+ tf/J (BTBR) mouse, a well-established animal model of ASD that exhibi…
Neuroinflammation is a hallmark of multiple sclerosis (MS). MS is marked by glial cell activation, autoreactive T cells, and the release of pro-inflammatory cytokines and free radicals. Current therapeutic strategies aim to modulate the immune response using disease-modifying therapies, to slow disease progression. The specific aims of this study were: (a) to investigate the effect of cannabinoid acids on the rele…
Fatty acid-binding protein 7 (FABP7) assists in the intracellular trafficking of endogenous cannabinoids and polyunsaturated fatty acids (PUFAs) and has been implicated for various psychiatric diseases. Rising evidence demonstrates the crosstalk between the endocannabinoid and dopaminergic systems, particularly in response to stress. The present study seeks to examine the role of FABP7 expression under chronic str…
The limited therapeutic options for metabolic dysfunction-associated steatotic liver disease (MASLD) underscore the need for deeper mechanistic insight and new treatment strategies. Here, we identify the orphan G protein-coupled receptor GPR146 as a regulator of hepatic steatosis through adipose-liver crosstalk. Human genetic analyses link the GPR146 locus to circulating markers of liver injury and inflammation. I…
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,…
Numerous exocrine glands play key physiological roles in the body that include tearing, salivation, and lactation, as well as the control of body temperature via sweating. Malfunction of sweat glands can be deeply problematic or-in the case of anhidrosis-life-threatening. The prevalence of sweating disorders is high, affecting millions. The few available therapies are generally of limited effectiveness. Several li…
Open article record in new tab ↗Reactive astrocytes shape central nervous system (CNS) inflammation and participate in myelin damage and repair mechanisms in multiple sclerosis (MS). Through the activation of cannabinoid CB1 receptors (CB1R) expressed by neurons and oligodendrocyte lineage cells, endocannabinoid signaling restricts neurodegeneration and promotes remyelination in preclinical MS models. However, despite accumulating evidence that…
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 ↗BACKGROUND: Post-traumatic headache (PTH) is a debilitating neurological sequela of mild traumatic brain injury (mTBI) characterized by secondary cephalic pain. The endocannabinoid system (ECS) is a critical modulator of nociception, yet the specific spatiotemporal changes in its metabolic machinery within cephalic pain circuits following mTBI are poorly understood. METHODS: Using in-situ hybridization (ISH), we f…
Open article record in new tab ↗Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder characterized primarily by chronic visceral pain, with a complex pathogenesis and limited efficacy of current therapeutic interventions. Growing evidence indicates that electroacupuncture (EA) and repetitive transcranial magnetic stimulation (rTMS) exert significant analgesic effects on visceral pain. However, the underlying neural cir…
Cisplatin-induced ototoxicity is a detrimental side effect of chemotherapy leading to hearing loss, for which no treatments are currently available. Despite the growing recognition of the endocannabinoid (eCB) system (ECS) as a significant contributor to different physiological and pathological processes, its role in hearing remains poorly investigated. To fill this knowledge gap, we performed a molecular profilin…
Serotonin (5-HT) plays an important role in shaping brain network dynamics by regulating excitatory synaptic function and neuronal excitability. However, much less is known about how 5-HT tunes synaptic inhibition. Here, we demonstrate that transient 5-HT signaling persistently suppresses GABAergic synapses onto layer 2/3 pyramidal neurons in the medial prefrontal cortex (mPFC). Moreover, we found that 5-HT1A and…
Background Navigation and memory are hippocampal functions that are essential for survival. One of the key modulators of hippocampal activity is the endocannabinoid system through the cannabinoid receptor type 1 (CB1). CB1 is widely expressed in various types of hippocampal cells. While it is known that CB1 participates in memory processes, its specific roles in different cell types and differences between sexes r…
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…
