Newest firstPeripheral cannabinoid CB1 receptor antagonists that lack central nervous system effects are emerging as promising therapies for metabolic disease, yet the role of endothelial CB1 signaling in atherosclerosis remains unclear. Here, we show that endothelial CB1 is expressed in human atherosclerotic plaques, is induced by oscillatory shear stress in atheroprone flow regions, and promotes vascular inflammation, perme…
Open article record in new tab ↗Purpose of review This paper reviews the existing literature supporting a role for fatty acid ethanolamides including oleoylethanolamide and palmitoylethanolamide in regulating cholesterol and triglyceride metabolism and the mechanisms underlying these effects. Recent findings Deletion of various fatty acid ethanolamide biosynthesis genes in cellular models and small animal models have provided additional evidence…
Open article record in new tab ↗Background Despite therapeutic advances, atherosclerosis remains a major global health challenge. Most current treatments target systemic risk factors rather than the diseased vascular wall. Our previous work identified genistein, a soy isoflavone, as a cannabinoid receptor 1 (CB1) antagonist capable of suppressing CB1-mediated vascular inflammation and atherosclerosis. However, its poor water solubility and low o…
Peripheral artery disease (PAD) is a progressive vascular disease characterized by atherosclerotic narrowing of peripheral arteries, resulting in decreased blood flow to the extremities. Common risk factors for PAD are diabetes, hypertension, and hyperlipidemia, although it can also occur in patients without these comorbidities, such as in the use of marijuana or alcohol. Recent research suggests that marijuana an…
Open article record in new tab ↗Objective Inflammation and repair responses may be involved in atherosclerosis in rheumatoid arthritis (RA), although mechanisms are unknown. GPR55, a cannabinoid receptor expressed in haematopoietic and stromal tissues, has been implicated in atherosclerosis in mouse models, but evidence in humans is lacking. Our aim was to evaluate GPR55 expression in leucocyte populations in RA and their potential role in ather…
Resistin, a cysteine-rich adipokine, exhibits significant species-specific divergence in its cellular origins and pathophysiological functions. In humans, it is primarily secreted by monocytes, macrophages, and bone marrow-derived cells, positioning it as a pivotal mediator of inflammation and cardiometabolic disease rather than a direct regulator of glucose metabolism. This review synthesizes current evidence on…
Open article record in new tab ↗Background: Myocardial infarction (MI) in young adults, once a rarity, is increasingly recognized as a distinct clinical entity. Unlike traditional MI patients, younger individuals often present without established risk factors or advanced atherosclerosis, prompting a reevaluation of pathophysiologic paradigms and risk assessment strategies. Objective: This review synthesizes current evidence on the epidemiology,…
Aims Although the cannabinoid CB1 receptor has been implicated in atherosclerosis, its cell-specific effects in this disease are not well understood. To address this, we generated a transgenic mouse model to study the role of myeloid CB1 signalling in atherosclerosis. Methods and results Here, we report that male mice with myeloid-specific Cnr1 deficiency on atherogenic background developed smaller lesions and nec…
Introduction Atherosclerosis (AS) is a chronic inflammatory disease characterized by lipid accumulation, inflammation and apoptosis of the arterial wall. This study evaluated the effects of lysophosphatidylinositol (LPI) on endothelial cells activation and autophagy in AS. Methods qRT-PCR and Western blotting were done to verify the expression of ICAM1, GPR55 and SOD2. RNA-Seq was performed and screened for the di…
Open article record in new tab ↗Background Studies on cannabis use and adverse cardiovascular outcomes have reported conflicting results. Research on its relationship to calcified arterial plaque remains limited. Methods Cross-sectional data from 2152 participants at Exam 6 (2016-2018) in the Multi-Ethnic Study of Atherosclerosis (MESA) were analyzed, including self-reported cannabis smoking patterns and carotid artery calcification (CAC) as mea…
Atherosclerosis is a major cause of cerebral and cardiovascular diseases. Intravascular plaques, a well-known pathological finding of atherosclerosis, have a necrotic core composed of macrophages and dead cells. Intraplaque macrophages, which are classified into various subtypes, play key roles in maintenance of normal cellular microenvironment. Excessive uptake of oxidized low-density lipoprotein causes conversio…
Open article record in new tab ↗Cardiovascular disease (CVD) causes millions of deaths worldwide each year. Despite the great progress in therapies available for patients with CVD, some limitations, including drug complications, still exist. Hence, the endocannabinoid system (ECS) was proposed as a new avenue for CVDs treatment. The ECS components are widely distributed through the body, including the heart and blood vessels, thus the action of…
Open article record in new tab ↗Background: The diagnosis, treatment, and prevention of atherosclerosis co-depression are poor, so it is urgent to explore new targets. Based on the "microbiota-gut-brain axis," this study aimed to investigate the changes of lipid metabolites in the prefrontal cortex and hippocampus regions and the characteristics of the gut microbiota in ApoE-/- mice with atherosclerosis co-depression. Methods: ApoE-/- mice (hype…
Open article record in new tab ↗Pharmacological blockade of the cannabinoid type 1 receptor, a G protein-coupled receptor expressed in the central nervous system and various peripheral tissues, reverses diet-induced obesity and dyslipidemia through the reduction of food intake and altered nutrient partitioning. This strategy is being explored for a number of therapeutic applications; however, its potency for the treatment of atherosclerotic card…
ZnO nanoparticles (ZnONPs) have been shown to have therapeutic potential in some diseases such as diabetes and cancer. However, concentration-dependent adverse effects have also been reported. Studies which evaluate the effects of ZnONPs on the cardiovascular system are scarce. This study aimed to evaluate the cardiovascular effects of a low dose of ZnONPs administered chronically in healthy rats. Changes in dysli…
GPR55 recognizes several lipid molecules such as lysophosphatidylinositol. GPR55 expression was reported in human monocytes. However, its role in monocyte adhesion and atherosclerosis development has not been studied. The role of GPR55 in monocyte adhesion and atherosclerosis development was investigated in human THP-1 monocytes and ApoE-/- mice using O-1602 (a potent agonist of GPR55) and CID16020046 (a specific…
Open article record in new tab ↗The incidence of atherosclerosis is increasing rapidly all over the world. Inflammatory processes have outstanding role in coronary artery disease (CAD) etiology and other atherosclerosis manifestations. Recently attentions have been increased about gut microbiota in many fields of medicine especially in inflammatory diseases like atherosclerosis. Ineffectiveness in gut barrier functions and subsequent metabolic e…
Background The endocannabinoid (eCB) 2-arachidonoylglycerol (2-AG) is a known modulator of inflammation and ligand to both, pro-inflammatory cannabinoid receptor 1 (CB1) and anti-inflammatory CB2. While the role of both receptors in atherogenesis has been studied extensively, the significance of 2-AG for atherogenesis is less well characterized. Methods The impact of 2-AG on atherogenesis was studied in two treatm…
Open article record in new tab ↗Monoglyceride lipase (MGL) hydrolyzes monoglycerides (MGs) to glycerol and fatty acids. Among various MG species MGL also degrades 2-arachidonoylglycerol (2-AG), the most abundant endocannabinoid and potent activator of cannabinoid receptors (CBR) 1 and 2. MGL-knockout (-/-) mice exhibit pronounced 2-AG accumulation, but lack central cannabimimetic effects due to CB1R desensitization. We have previously shown that…
