N-arachidonoylethanolamine (AEA) and 2-arachidonoylglycerol (2-AG) are lipid signalling molecules within the endocannabinoid system, which regulates numerous physiological processes and is implicated in diverse pathological conditions. Given the limited feasibility of obtaining human tissue samples, quantifying AEA and 2-AG in biological matrices is essential for understanding the endocannabinoid system in humans.…
BACKGROUND: Oleoylethanolamide (OEA) is an endogenous lipid mediator involved in nutrient sensing and gut-derived hormonal signalling. TRPTI™ is a bioavailable OEA formulation designed to support metabolic and appetite-related pathways. This study evaluated the acute metabolic effects of TRPTI™ in healthy adults under controlled feeding conditions. METHODS: In this fixed-sequence, single-blind, placebo-controlled,…
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…
Gulf War Illness (GWI) affects 32% of Veterans from the 1990-1991 Gulf War. It is characterized by fatigue, mood disturbances, pain and cognitive decrements, with no FDA-approved treatment. This exploratory randomized, double-blind, placebo-controlled trial evaluated the safety and efficacy of oleoylethanolamide (OEA) supplementation in 52 Veterans with GWI (mean age 59 ± 5 SD, 94% males and 79% White). Participan…
IntroductionOsteoarthritis (OA) is a chronic, progressive joint disorder with higher prevalence and pain severity in women than men. The endocannabinoid system (ECS) modulates pain and shows sexual dimorphism, yet sex-specific alterations in central ECS signalling in OA pain remain under-investigated.ObjectivesWe investigated sex-dependent differences in pain-related behaviours and central ECS signalling in the ra…
BACKGROUND: Autosomal dominant polycystic kidney disease (ADPKD) is characterized by progressive cyst formation, inflammation, and metabolic dysregulation. The endocannabinoid system (ECS), particularly the cannabinoid-1 receptor (CB1R), regulates renal metabolism and inflammatory signaling, yet its role in ADPKD remains largely unexplored. METHODS: We analyzed publicly available human kidney transcriptomic datase…
Background/Objectives: Lipedema is a chronic adipose tissue disorder characterized by disproportionate fat accumulation, pain, microvascular dysfunction, and low-grade inflammation. Although low-carbohydrate, high-fat (LCHF) dietary approaches are increasingly used in clinical practice, their longer-term associations with vascular, lymphatic, and immunometabolic pathways in lipedema remain insufficiently understoo…
Endocannabinoids (eCBs) are lipid-derived neuromodulators that regulate numerous neurophysiological processes by modulating synaptic transmission. Synthesised on demand in response to increased postsynaptic intracellular calcium or activation of postsynaptic G-protein coupled receptors, eCBs are rapidly degraded, resulting in transient, tightly regulated signalling. Dysregulation in the endocannabinoid system (ECS…
BACKGROUND: Cannabidiol (CBD), a phytocannabinoid produced by Cannabis sativa, is widely consumed and interacts with components of the endocannabinoid system, including enzymes and receptors, through indirect and complex mechanisms. However, how CBD influences endogenous cannabinoids such as anandamide (AEA), and related N-acylethanolamines like N-palmitoylethanolamine (PEA) and N-oleoylethanolamine (OEA), remains…
Pharmacological treatment of metabolic-dysfunction-associated steatohepatitis remains challenging due to its complex pathophysiology. The endocannabinoidome (eCB) has emerged as a promising therapeutic target given its central role in energy homeostasis and its pharmacological tractability. Western-style diets high in fat and sugar exacerbate metabolic liver disease, highlighting the need for effective interventio…
High fructose diet is a major risk factor for metabolic syndrome (MetS). The gut bacterium Akkermansia muciniphila (A. muciniphila) has been shown to improve fructose-induced MetS, but the underlying mechanism remains unclear. Here, we investigated how A. muciniphila modulates fructose-induced MetS using multitissue, multiomics studies encompassing gut microbiota, plasma and gut metabolome, and hypothalamus single…
Rationale Exposure to traumatic events can lead to alterations in social and anxiety-related behaviors. Emerging evidence suggests that peripheral host-defense processes are implicated in the expression of stress-induced behavioral responses and may be targeted to mitigate the negative sequalae of stress exposure. Objectives In this study, we used the peripherally restricted FAAH inhibitor URB937 to investigate th…
The intestine plays a crucial role in nutrient absorption, digestion, and regulation of metabolic processes. Intestinal structure and functions are influenced by several factors, with dietary composition being one of the most significant. Diets rich in various types of fats, including saturated, monounsaturated, and polyunsaturated fats, have distinct effects on intestinal cell metabolism and overall intestinal he…
Rationale Social stress contributes to the development of depressive and anxiety symptomatology and promotes pro-inflammatory signaling in the central nervous system. In this study, we explored the effects of a lipid messenger with anti-inflammatory properties - oleoylethanolamide (OEA) - on the behavioral deficits caused by social stress in both male and female mice. Methods Adult mice were assigned to an experim…
Objective In intensive care, delirium is frequent, prolongs the stay, increases health care costs, and worsens patient outcome. Several substances and medications as well as stress can impact the risk of delirium; however, assessment of previous exposure to psychotropic agents and stress by self-reports or third-party information is not always reliable. Hair analysis can be used to objectively assess medication an…
Introduction Autism spectrum disorder (ASD) is characterized by disruption of the gut-brain axis, which leads to behavioral, psychiatric, metabolic and gastrointestinal symptoms. Effective ASD treatments are limited. Research highlights the roles of the endocannabinoidome (eCBome) and gut microbiome (GM), both crucial for brain and gut function. This review summarizes research on therapeutic targets within the eCB…
Introduction The microbiological safety of donor milk (DM) is commonly ensured by holder pasteurization (HoP, 62.5°C for 30 min) in human milk banks despite its detrimental effects on several bioactive factors. We compared the concentration of twelve endocannabinoid (eCB)-like mediators in raw DM and in DM after holder pasteurization or high hydrostatic pressure processing (HHP, 350 MPa at 38°C), a non-thermal sub…
Introduction Pain constitutes the chief complaint of some functional gastrointestinal disorders (FGIDs). The endocannabinoid (EC) and peroxisome proliferator-activated receptors (PPARs) agonist systems have not been explored as possible contributors. Objective To determine if EC and PPAR agonist abnormalities occur in adolescents with FGID. Methods Institutional Review Board approved study compared 33 children (12…
Objective Although peripheral endocannabinoid system (ECS) signatures have been implicated in ADHD among European and American populations, evidence from Asian pediatric cohorts remains scarce. This study quantified serum concentrations of four major endocannabinoids-anandamide (AEA), 2-arachidonoylglycerol (2-AG), oleoylethanolamide (OEA), and palmitoylethanolamide (PEA)-in treatment-naïve Han Chinese children wi…
Background and aims Intestinal fibrosis, a frequent complication of inflammatory bowel disease, is characterized by stricture formation with no pharmacological treatment to date. N-acylethanolamine acid amidase (NAAA) is responsible for the hydrolysis of acylethanolamides (AEs, eg, palmitoylethanolamide and oleoylethanolamide). Here, we investigated NAAA and AE signaling in gut fibrosis. Methods NAAA and AE signal…
