Recently, it has been described the role of fatty acid ethanolamides in the control of feeding behavior. Oleoylethanolamide (OEA) is a member of this family of lipid mediators regulating feeding. OEA acts suppressing feeding behavior through, at least partially, a peripheral mechanism. However, the interaction between this acylethanolamide and other(More)
We have modelled elaidyl-sulfamide (ES), a sulfamoyl analogue of oleoylethanolamide (OEA). ES is a lipid mediator of satiety that works through the peroxisome proliferator-activated receptor alpha (PPARα). We have characterised the pharmacological profile of ES (0.3-3 mg/kg body weight) by means of in silico molecular docking to the PPARα receptor, in vitro(More)
β-adrenergic receptor activation promotes brown adipose tissue (BAT) β-oxidation and thermogenesis by burning fatty acids during uncoupling respiration. Oleoylethanolamide (OEA) can inhibit feeding and stimulate lipolysis by activating peroxisome proliferator-activating receptor-α (PPARα) in white adipose tissue (WAT). Here we explore whether PPARα(More)
BACKGROUND Endocannabinoids modulate the glutamatergic excitatory transmission by acting as retrograde messengers. A growing body of studies has reported that both signaling systems in the mesocorticolimbic neural circuitry are involved in the neurobiological mechanisms underlying drug addiction. METHODS We investigated whether the expression of both(More)
Recent studies have identified biomarkers related to the severity and pathogenesis of cocaine addiction and common comorbid psychiatric disorders. Monitoring these plasma mediators may improve the stratification of cocaine users seeking treatment. Because the neurotrophic factors are involved in neural plasticity, neurogenesis and neuronal survival, we have(More)
Addiction to major drugs of abuse, such as cocaine, has recently been linked to alterations in adult neurogenesis in the hippocampus. The endogenous cannabinoid system modulates this proliferative response as demonstrated by the finding that pharmacological activation/blockade of cannabinoid CB1 and CB2 receptors not only modulates neurogenesis but also(More)
Endocannabinoid signalling participates in the control of neurogenesis, especially after brain insults. Obesity may explain alterations in physiology affecting neurogenesis, although it is unclear whether cannabinoid signalling may modulate neural proliferation in obese animals. Here we analyse the impact of obesity by using two approaches, a high-fat diet(More)
Soy extracts have been claimed to be neuroprotective against brain insults, an effect related to the estrogenic properties of isoflavones. However, the effects of individual isoflavones on obesity-induced disruption of adult neurogenesis have not yet been analyzed. In the present study we explore the effects of pharmacological administration of daidzein, a(More)
Anandamide and oleoylethanolamide (OEA) are lipid mediators that regulate feeding and lipid metabolism. While anandamide, a cannabinoid CB1 receptor agonist, promotes feeding and lipogenesis, oleoylethanolamide, an endogenous agonist of peroxisome proliferator activated receptor alpha (PPAR-alpha), decreases food intake and activates lipid mobilization and(More)
Endocannabinoids (anandamide and 2-AG) are relevant modulators of appetite and energy expenditure through their action on cannabinoid CB(1) receptors. The actions of anandamide on feeding behavior are dependent both, on the anatomical location of CB(1) receptors (central nervous system versus peripheral tissues) and the feeding status. Anandamide uptake(More)
