Newest firstN-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.…
Open article record in new tab ↗Binge drinking contributes to an increasing number of emergency department visits in the United States. Previous work demonstrated that an alcohol binge impairs cardiac performance and exerts complex hemodynamic effects through the activation of the endocannabinoid-mediated cannabinoid type 1 receptor (CB1R) signaling pathway. Anandamide (AEA), an endogenous CB1R agonist, is synthesized in response to various stre…
Object recognition memory (ORM) plays a key role in identifying familiar items and encoding episodic information. ORM consolidation depends on β-adrenergic receptor (βAR) signaling and is associated with increased BDNF expression in the dorsal hippocampus. Although hippocampal activation of cannabinoid type-1 receptors (CB1Rs) is known to impair ORM consolidation, the mechanisms underlying this effect remain uncle…
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.…
Open article record in new tab ↗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…
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…
Open article record in new tab ↗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…
Open article record in new tab ↗Background This SONRIE randomized controlled trial (NCT05849792) examined the effects of a 12-week combined physical exercise and internet-based cognitive-behavioral therapy (iCBT) intervention on endocannabinoid system (ES) biomarkers and physical fitness in adults with mild-to-moderate depression. Methods Eighty adults were randomly assigned 1:1 to an intervention (IG) or control (CG) group. Outcomes included ni…
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…
Numerous exocrine glands play key physiological roles in the body that include tearing, salivation, and lactation, as well as the control of body temperature via sweating. Malfunction of sweat glands can be deeply problematic or-in the case of anhidrosis-life-threatening. The prevalence of sweating disorders is high, affecting millions. The few available therapies are generally of limited effectiveness. Several li…
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…
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…
Open article record in new tab ↗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…
The endocannabinoid system is a complex regulatory network whose functioning is associated with maintaining homeostasis and regulating immune response. The aim of this study was to evaluate the relationship between endocannabinoid system activity, inflammation, and the progression of chronic kidney disease (CKD) in patients with autosomal dominant polycystic kidney disease (ADPKD). The study included 105 participa…
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…
Fatty acid amide hydrolase (FAAH) is a central component of the endocannabinoid system (ECS), where it primarily regulates intracellular levels of anandamide (AEA) through enzymatic hydrolysis. Although FAAH has been extensively studied in neural and immune contexts, its involvement in female reproductive physiology is receiving increasing attention. Accumulating evidence indicates that FAAH participates in severa…
Open article record in new tab ↗Background Childhood absence epilepsy (CAE) arises from dysfunctional corticothalamic networks generating spike wave discharges (SWDs) and behavioral arrest. Despite available treatments, a significant proportion of patients remain pharmacoresistant and develop neuropsychiatric comorbidities. The endocannabinoid system (ECS), through activity-dependent signaling, is a key regulator of synaptic and network stabilit…
Open article record in new tab ↗Post-traumatic stress disorder (PTSD) is a severe mental health disorder with limited treatment options. Gold standard treatment includes cognitive behavioral therapies (CBT) that incorporate exposure to traumatic memories to facilitate extinction. CBT can be effective in PTSD, but effects are incomplete and symptoms are prone to spontaneous return. Pharmacologically facilitating fear extinction could potentiate t…
BackgroundSynaptic dysfunction underlies early sensorimotor and cognitive deficits in Huntington's disease (HD) and precedes the degeneration of striatal spiny projection neurons and cortical pyramidal neurons. Movement selection and motor learning, which are impaired early in HD, are regulated by connections between the motor cortex, basal ganglia and thalamus. In particular, plasticity at corticostriatal synapse…
The present study investigates the concentrations of the endocannabinoids under standardized psychosocial stress induction (TSST) and a resting condition in healthy males. Hereby, all endocannabinoids were analyzed under a standardized laboratory procedure (arachidonic acid (AA), arachidonoylethanolamide (AEA), isomeres 2-AG arachidonoylglycerol (2-AG) and palitoylethanolamide (PEA)). A total of n = 32 healthy con…
