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.…
Anxiety disorders are associated with impaired inhibitory neurotransmission mediated by γ-aminobutyric acid type A (GABA-A) receptors. Although benzodiazepines remain effective anxiolytics, their clinical utility is limited by sedation, cognitive impairment, tolerance, and dependence, prompting the search for mechanistically distinct GABAergic modulators. Among cannabinoid-related molecules, the strongest evidence…
Headache disorders, including migraine, tension-type headache, trigeminal autonomic cephalalgias, post-traumatic headache and medication overuse headache, represent a major global health burden and remain difficult to treat despite therapeutic advances. The endocannabinoid system (ECS) has emerged as a key regulator of neural, vascular, and immune processes central to headache pathophysiology. Through coordinated…
The endocannabinoid system (ECS) and the autophagy receptor p62 are both implicated in metabolic regulation and obesity, yet the mechanisms linking these pathways remain unclear. Here, we investigated whether p62 modulates CB1 receptor (CB1R) turnover or function and whether CB1R contributes to the metabolic phenotype of p62 knockout (KO) mice. In primary cortical neurons from wild-type mice, inhibition of autopha…
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.…
Rationale Traumatically injured individuals can develop chronic negative psychological sequelae. Improved understanding of contributing, peri-traumatic risk factors is essential to reduce the risk of these consequences. Previous studies have found that peri-traumatic, circulating endocannabinoid concentrations are positively associated with development of post-traumatic stress disorder (PTSD), chronic pain and dep…
Adolescent depression emerges during a developmental period characterized by ongoing maturation of corticolimbic and stress-regulatory systems. This narrative review critically evaluates a hypothesis that acute exercise-related endocannabinoid mobilization, particularly changes in circulating anandamide (AEA), may be linked to CB1 receptor (CB1R)-dependent processes relevant to prefrontal–amygdala function and str…
Rationale Harmful alcohol use remains a significant global public health challenge. Examining variability in the acute subjective effects of alcohol and related neurobiological mechanisms may advance the understanding of susceptibility to harmful alcohol use. Research suggests the endocannabinoid (eCB) system may play an important role in mediating the reinforcing effects of alcohol. This study examined the relati…
Major depressive disorder (MDD) refers to a complex mental disorder defined by hindered reward system and hindered stress resilience. The limitations of traditional monoamine antidepressants have prompted the academic community to study new pathological processes and intervention strategies. Major depressive disorder arises from a complex interplay of psychological, social, and biological factors. Among the latter…
Rationale The ongoing global opioid crisis underscores the need to better understand the neurobiological mechanisms underlying opioid use disorder (OUD). Stress is a key risk factor for developing and maintaining OUD. While animal models report that the endocannabinoid system (ECS) plays a modulatory role in stress response, alterations of ECS stress reactivity in individuals with OUD have yet to be studied. Objec…
The comorbidity of chronic pain and mood disorders poses a clinical challenge involving neurobiological mechanisms within key brain regions like the ventral tegmental area (VTA). We employed a multidisciplinary approach in male mice, combining proteomics, phosphoproteomics, and lipidomics with behavioral and immunohistochemical analyses in a neuropathic pain model. Our findings reveal a temporal evolution of the V…
Background Depression is a leading cause of global disability, affecting approximately 280 million individuals worldwide. Emerging evidence suggests that both physical fitness and endocannabinoids system play significant roles in the pathophysiology and management of depressive disorders. Purpose To examine the associations between physical fitness, in terms of cardiorespiratory fitness (CRF) and muscular fitness…
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…
Hypertensionis one of the leading causes of cardiovascular disease and premature death worldwide, affecting more than 1.2 billion adults, with a significant part living in low- and middle-income countries. Pediatric hypertension is also a growing concern, with an estimated 4.5% of children in the United States affected. The 2024 European Society of Cardiology guidelines provide updated protocols for diagnosing and…
Monoacylglycerol lipase (MAGL) is a key enzyme at the interface between the endocannabinoid system and lipid metabolism, playing a pivotal role in the hydrolysis of the endocannabinoid 2-arachidonoylglycerol and in the regulation of lipid mediators involved in inflammation, pain, neurodegeneration and cancer. Owing to its therapeutic relevance, MAGL has emerged as an attractive pharmacological target, stimulating…
Background Heat stress (HS) poses a significant challenge to dairy production under climate change, as it compromises fertility, productivity and overall health in cows. This seasonal observational cross-sectional study investigated how environmental temperature affects oxidative status, inflammatory responses and endocannabinoid system (ECS) in dairy cows, comparing winter and summer conditions. Methods Sixty Ita…
Background The endocannabinoid system (ECS) is a complex signaling network that regulates diverse physiological processes, including pain, mood, metabolism, and immune response, through coordinated interactions among receptors, enzymes, and lipid-derived ligands. Although individual ECS components have been extensively studied, the integrated systems-level organization and structural dependencies of the ECS remain…
The endocannabinoid system (ECS) is involved in regulating immune functions in leukocytes. An inflammatory stimulus, specifically LPS, can modulate the activity of endocannabinoids (eCB) receptors, and eCB within the leukocytes can further exert either pro- or anti-inflammatory effects on the immune function of these cells. The effects of exogenous eCB on the cellular inflammatory responses of bovine leukocytes ar…
Rationale Adverse childhood experiences (ACEs) have been identified as a major risk factor for psychiatric disorders from childhood to adult life along with the dysregulation of neuroendocrinological processes mediating stress and inflammation. The endocannabinoid system (ECS) has been found to play a putative role in the release of inflammatory cytokines. Objective We investigated the role of the ECS in the inter…
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…
