Newest firstBACKGROUND: 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,…
Open article record in new tab ↗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…
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…
Open article record in new tab ↗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…
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…
Open article record in new tab ↗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…
Oleoylethanolamide (OEA) is a lipid with anti-inflammatory activity that modulates multiple reward-related behaviors. Previous studies have shown that OEA treatment reduces alcohol self-administration (SA) while inhibiting alcohol-induced inflammatory signaling. Nevertheless, the specific mechanisms that OEA targets to achieve these effects have not been widely explored. Here, we tested the effects of OEA treatmen…
Background Abnormalities in biochemical parameters and changes in eating habits are considered complications of obesity. Oleoylethanolamide (OEA), an endocannabinoid-like compound, has been shown to have protective effects on many metabolic disorders. Given this evidence, the present study aimed to assess the effects of OEA on lipid profile parameters, fasting blood sugar (FBS), and dietary habits in healthy obese…
Open article record in new tab ↗Background Age is the strongest risk factor for the development of Alzheimer's disease (AD). Besides the pathological hallmarks of β-amyloid (Aβ) plaques and neurofibrillary tangles, emerging evidence demonstrates a critical role of microglia and neuroinflammation in AD pathogenesis. Oleoylethanolamide (OEA) is an endogenous lipid amide that has been shown to promote lifespan and healthspan in C. elegans through r…
The lipid oleoylethanolamide (OEA) has been shown to affect reward-related behavior. However, there is limited experimental evidence about the specific neurotransmission systems OEA may be affecting to exert this modulatory effect. The aim of this study was to evaluate the effects of OEA on the rewarding properties of cocaine and relapse-related gene expression in the striatum and hippocampus. For this purpose, we…
There is growing evidence that perturbation of the gut microbiome, known as "dysbiosis", is associated with the pathogenesis of human and veterinary diseases that are not restricted to the gastrointestinal tract. In this regard, recent studies have demonstrated that dysbiosis is linked to the pathogenesis of central neuroinflammatory disorders, supporting the existence of the so-called microbiome-gut-brain axis. T…
Open article record in new tab ↗Oleoylethanolamide and palmitoylethanolamide are members of the fatty acid ethanolamide family, also known as acylethanolamides. Their physiological effects, including glucose homeostasis, anti-inflammation, anti-anaphylactic, analgesia, and hypophagia, have been reported. They have affinity for different receptor proteins, including nuclear receptors such as PPARα, channels such as TRPV1, and membrane receptors s…
Open article record in new tab ↗Oleoylethanolamide (OEA) is a naturally occurring bioactive lipid belonging to the family of N-acylethanolamides. A variety of beneficial effects have been attributed to OEA, although the greater interest is due to its potential role in the treatment of obesity, fatty liver, and eating-related disorders. To better clarify the mechanism of the antiadipogenic effect of OEA in the liver, using a lipidomic study perfo…
Background The endogenous cannabinoid system mediates the psychoactive effects of cannabis in the brain. It has been argued that this system may play a key role in the pathophysiology of schizophrenia. While some studies have consistently shown that the levels of anandamide, an endogenous cannabinoid ligand, are increased in the cerebrospinal fluid of schizophrenia patients, inconsistent results have been observed…
Open article record in new tab ↗Oleoylethanolamide is an endogenous NAE that modulates ethanol-seeking behavior and ethanol-induced neuroinflammation. In the present study we further analyze the role of OEA in hippocampal neurogenesis, BDNF-ERK signaling, and spatial memory that are affected by alcohol. Additionally, we addressed the effects of OEA on the association of alcohol and cannabis, a frequent combination in human alcohol addicts, and w…
Purpose: Obesity as a serious public health problem worldwide, results in the incidence of many chronic diseases. Obesity has been recognized as a chronic low-grade inflammation disorder. Altered endocannabinoid system tone is also involved in the pathogenesis of obesity. The present study aimed to investigate the effects of oleoylethanolamide supplementation on inflammatory biomarkers and oxidative stress in obes…
Open article record in new tab ↗Background Chronic widespread pain conditions (CWP) such as the pain associated with fibromyalgia syndrome (FMS) are significant health problems with unclear aetiology. Although CWP and FMS can alter both central and peripheral pain mechanisms, there are no validated markers for such alterations. Pro- and anti-inflammatory components of the immune system such as cytokines and endogenous lipid mediators could serve…
