Newest firstOveractivation of the endocannabinoid (EC) system is an important pathogenic factor in the development of obesity. The inactivation of the EC system through administration of cannabinoid receptor 1 (CB1R) antagonist or CB1R knockout can ameliorate obesity-associated metabolic disorders such as insulin resistance and compensatory hyperinsulinemia and hepatic steatosis. However, the specific mechanisms by which hype…
Open article record in new tab ↗The mechanisms underlying wound healing mediated by cannabinoid receptor 1 (CB1)-known for its neuromodulatory functions-remain incompletely understood. Therefore, we investigated the impact of activating CB1 using specific agonists, both in vitro and in vivo, with a focus on wound healing. In the in vitro study, fibroblasts were isolated and cultured from the dermis of human skin and treated with a CB1 agonist, 2…
The transcriptional regulation of the cannabinoid receptor 1 (CB1R) by promoter/enhancer elements and transcription factors is an area of cannabinoid research that has historically been understudied. To map the promoter region of the human CNR1 gene (the gene encoding CB1R), a 997-base-pair fragment from the sequence upstream of the CNR1 gene was cloned into a secreted luciferase reporter vector, and a series of d…
Open article record in new tab ↗Drug-resistant epilepsy is often associated with a neurodevelopmental disorder, focal cortical dysplasia (FCD). As demonstrated by numerous studies, defects in perisomatic inhibition may play a role in the formation of seizures. In our previous study, we observed an increase in parvalbumin-immunopositive perisomatic input. It has been observed that other perisomatic inhibitory cells expressing cannabinoid receptor…
The amygdala is composed of several nuclei, including the lateral nucleus which is the main receiving area for the input from cortical and subcortical brain regions. It mediates fear, anxiety, stress, and pain across species. Evidence suggests that the endocannabinoid system may be a promising target for modulating these processes. Cannabinoid and cannabinoid-related receptors have been identified in the amygdala…
Previous studies performed on the European eel Anguilla anguilla showed changes in the morphology and physiology of several tissues after exposure to environmental cocaine concentrations. To better understand the model through which cocaine produced its effects on these tissues, we investigated whether there were alterations in the expression of cannabinoid CB1 receptor (CB1R). Indeed, the endocannabinoid system,…
Open article record in new tab ↗The cannabinoid receptor 1 (CB1R) regulates cardiovascular functions and is activated by agonists such as WIN55,212-2. While CB1R activation is known to influence blood pressure and oxidative stress both centrally and peripherally, the downstream mechanisms remain unclear. The kinin B1 receptor (B1R), induced by stress and inflammation, may function as a signaling partner for CB1R. This study investigated whether…
Open article record in new tab ↗Aims A review of the published literature was done to understand the role of endocannabinoids in glaucoma. Background As evidence mounts that intraocular pressure (IOP) is not the only factor in the pathogenesis and progression of glaucoma, a look into other aspects is the need of the hour. From the first instance of a drop in IOP linked to marijuana in the 1970s to the present, research has been ongoing, mostly i…
Objective Emerging evidence suggests lipid metabolism dysregulation contributes to autism spectrum disorders (ASD), with the endocannabinoid system (cannabinoid receptors CB1R/CB2R) implicated in lipid homeostasis. This study investigated whether CB1R/CB2R activation improves hippocampal lipid metabolism and ASD-like behaviors in a valproic acid (VPA)-induced ASD rat model. Methods Male offspring from dams exposed…
The endocannabinoid system is a critical brain signaling pathway that is dysregulated in various brain disorders, including Alzheimer's disease (AD). Cannabinoid-targeted therapies and imaging approaches have gained increasing interest; however, the biological impact of the endocannabinoid system in disease needs further validation. We aimed to study changes in cannabinoid receptor 1 (CB1) and monoacylglycerol lip…
Fibromyalgia is a chronic illness usually accompanied by long-lasting, general pain throughout the body, often accompanied by anxiety, depression, fatigue, and sleep disruption. Meanwhile, doctors and scientists have not entirely discovered detailed mechanisms; patients always have an exaggerated sensation to pervasive pain without satisfied medical service. Given the lack of knowledge on its underlying mechanism,…
In childhood, retinoblastoma (RB) is the most common primary tumor in the eye. Long term therapeutic management with etoposide of this life-threatening condition may have diminishing effectiveness since RB cells can develop cytostatic resistance to this drug. To determine whether changes in receptor-mediated control of Ca2+ signaling are associated with resistance development, fluorescence calcium imaging, semi-qu…
The cannabinoid receptor 1 (CB1) is famous as the target of Δ9-tetrahydrocannabinol (THC), which is the active ingredient of marijuana. Suppression of CB1 is frequently suggested as a drug target or gene therapy for many conditions (e.g., obesity, Parkinson's disease). However, brain networks affected by CB1 remain elusive, and unanticipated psychological effects in a clinical trial had dire consequences. To bette…
Endocannabinoid signalling mediated by cannabinoid receptor 1 (CB1R, also known as CNR1) is critical for homeostatic neuromodulation of both excitatory and inhibitory synapses. This requires highly polarised axonal surface expression of CB1R, but how this is achieved remains unclear. We previously reported that the α-helical H9 domain in the intracellular C terminus of CB1R contributes to axonal surface expression…
Introduction The contribution of Cannabinoid type 1 receptor (CB1) in mitochondrial energy transduction mechanisms and mitochondrial activities awaits deeper investigations. Our study aims to assess the impact of CB1 absence on the mitochondrial compartment in the liver, focusing on both functional aspects and remodeling processes. Methods We used CB1-/- and CB1+/+ male mice. Cytochrome C Oxidase activity was dete…
Parkinson's disease (PD) is a prevalent degenerative movement disorder largely attributed to the dysfunction of dopamine transmission in the basal ganglia. However, the role of the endocannabinoid (eCB) system (ECS) in PD pathology and symptomatology is often overlooked in discussions. Recent research, including our own, has identified multiple homozygous loss-of-function variants in diacylglycerol lipase β (DAGLB…
Introduction This study aimed to identify the effect of electroacupuncture (EA) treatment on post-stroke depression (PSD) and explore whether cannabinoid receptor 1 (CB1R)-mediated mitochondrial biogenesis accounts for the treatment effect of EA. Methods The PSD mouse model was induced by a consecutive 14-day chronic unpredictable stress operation after 7 days of recovery from the bilateral common carotid artery o…
In the central nervous system (CNS), cannabinoid receptor 1 (CB1R) is preferentially expressed in axons where it has a unique property, namely resistance to agonist-driven endocytosis. This review aims to summarize what we know about molecular mechanisms of CB1R cell surface stability in axonal compartments, how these impact CB1R signaling, and to consider their physiological consequences. This review then focuses…
Open article record in new tab ↗Emerging evidence indicates that the endogenous cannabinoid system modulates the behavioral and physiological effects of nicotine. Fatty acid-binding proteins (FABPs) are among the primary intracellular trafficking mechanisms of endogenous cannabinoids, such as anandamide. To this end, changes in FABP expression may similarly impact the behavioral manifestations associated with nicotine, particularly its addictive…
Endocannabinoid signaling plays crucial roles in human physiology in the function of multiple systems. The two cannabinoid receptors, CB1 and CB2, are cell membrane proteins that interact with both exogenous and endogenous bioactive lipid ligands, or endocannabinoids. Recent evidence has established that endocannabinoid signaling operates within the human kidney, as well as suggests the important role it plays in…
