Newest firstPalmitoylethanolamide (PEA) is an endogenous lipid mediator with immunomodulatory actions, yet its effects in skeletal muscle remain poorly defined. We examined whether PEA influences myogenesis and profiled the acute transcriptomic response of differentiated C2C12 myotubes to 10 μM PEA. PEA decreased myotube number (90.3 ± 10.6 vs. 112.6 ± 10.1 control) while increasing nuclear fusion index (37.8 ± 5.7% vs. 30.7…
Open article record in new tab ↗Background/objectives Osteoarthritis (OA) is a leading cause of chronic pain. As healthcare services struggle to meet demand to treat chronic pain, many individuals self-manage their symptoms. Probiotics and palmitoylethanolamide (PEA) may be promising therapeutic options because of their anti-inflammatory properties. PEA is an endogenously produced N-acylethanolamine, considered "endocannabinoid-like" due to its…
Open article record in new tab ↗Several studies show that neurosteroids currently play a significant role in autism spectrum disorders (ASD). However, the pathway of neurosteroid synthesis involved in ASD remains unclear. This study aimed to investigate the crosstalk between autism and neurosteroids, focusing on the mechanism of allopregnanolone production. We used the BTBR T+ tf/J (BTBR) mouse, a well-established animal model of ASD that exhibi…
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 ↗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…
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…
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…
Graft-versus-host disease (GVHD), a secondary complication of bone marrow transplantation, leads to the development of a systemic inflammatory illness in the host, resulting in high mortality and morbidity. Current therapies lack prophylactic effectiveness and often fail to achieve an optimal immunological balance between inflammation and immunosuppression. In this study, we investigated the effects of palmitoylet…
Maintaining a quiescent uterus until labor is of utmost importance for a successful pregnancy and still represents the most challenging issue in clinical practice. Despite the existence of standard approaches (short-term use of tocolytic agents or preventive use of vaginal progesterone), whose efficacy is still controversial, several natural molecules have garnered attention in recent years as an effective therape…
Background: The blood-brain barrier (BBB) plays a critical role in protecting the central nervous system (CNS) but also limits drug delivery. Insufficient knowledge of how the CNS promotes the onset and maintenance of peripheral neuropathic pain limits therapeutic methods for the treatment of persistent neuropathic pain. Thus, this study aimed to evaluate the ability of a novel combination of Palmitoylethanolamide…
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…
Background Palmitoylethanolamide (PEA) is an endocannabinoid-like lipid mediator which is naturally produced in the body and found in certain foods. The aim of this study was to assess the effect of a bioavailable formulated form of PEA (Levagen+®) on serum BDNF levels and parameters of cognitive function in healthy adults. Methods A randomised double-blinded placebo-controlled cross-over trial was implemented to…
Open article record in new tab ↗Background The mental health benefits of cannabidiol (CBD) are promising but can be inconsistent, in part due to challenges in defining an individual's effective dosage. In schizophrenia, alterations in anandamide (AEA) concentrations, an endocannabinoid (eCB) agonist of the eCB system, reflect positively on treatment with CBD. Here, we expanded this assessment to include eCBs alongside AEA congeners, comparing ph…
Opioid-related overdose deaths are still on the rise in North America, emphasizing the need to better understand the underlying neurobiological mechanisms regarding the development of opioid use disorder (OUD). Recent evidence from preclinical and clinical studies indicate that the endocannabinoid system (ECS) may play a crucial role in stress and reward, both involved in the development and maintenance of substan…
Open article record in new tab ↗Background The endocannabinoid (eCB) system and the serotonin (5-HT) are both implicated in the severity of the depression. 5-HT is synthesized from the amino acid tryptophan (Trp), which is also a precursor for kynurenine (Kyn) whose production is increased at the expense of 5-HT in depressed patients. No clinical studies have investigated the crosstalk between the eCB system and the Trp/5-HT/Kyn pathways. Here,…
Oleoylethanolamide (OEA) and palmitoylethanolamide (PEA) are endogenous lipids that act as agonists of the peroxisome proliferator-activated receptor α (PPARα). Recently, an interest in the role of these lipids in malignant tumors has emerged. Nevertheless, the effects of OEA and PEA on human neuroblastoma cells are still not documented. Type I interferons (IFNs) are immunomodulatory cytokines endowed with antivir…
Background Allergic rhinitis (AR) is an inflammatory, symptomatic disorder stimulated by antigen-specific immunoglobulin E inflammation in response to allergens. Current treatments include the use of corticosteroids and antihistamines to reduce inflammation by preventing histamine release. Palmitoylethanolamide (PEA) is reported to be an alternative treatment, shown to downregulate mast cell activation and increas…
Open article record in new tab ↗COVID-19 can cause symptoms that last weeks or months after the infection has gone, with a significant impairment of quality of life. Palmitoylethanolamide (PEA) is a naturally occurring lipid mediator that has an entourage effect on the endocannabinoid system mitigating the cytokine storm. The aim of this retrospective study is to evaluate the potential efficacy of PEA in the treatment of long COVID. Patients att…
Palmitoylethanolamide (PEA) is an endogenous anti-inflammatory lipid mediator and a widely used nutraceutical. In this study, we designed, realized, and tested a drug-carrier conjugate between PEA (the active drug) and glucuronic acid (the carrier). The conjugate, named GLUPEA, was characterized for its capability of increasing PEA levels and exerting anti-inflammatory activity both in vitro and in vivo. GLUPEA tr…
All nations which have undergone a nutrition transition have experienced increased frequency and falling latency of chronic degenerative diseases, which are largely driven by chronic inflammatory stress. Dietary supplementation is a valid strategy to reduce the risk and severity of such disorders. Palmitoylethanolamide (PEA) is an endocannabinoid-like lipid mediator with extensively documented anti-inflammatory, a…
