The endocannabinoids anandamide and 2-arachidonyl glycerol (2-AG) bind to G protein-coupled central and peripheral cannabinoid receptors CB1 and CB2, respectively. Due to the relatively high expression of the CB2 isotype on peripheral immune cells, it has been hypothesized that this receptor
BACKGROUND
There are conflicting views in the literature as to whether cannabinoids have an impact on platelet activity and to what extent cannabinoid receptors are involved. This is an important issue to resolve because platelet effects of putative therapeutic cannabinoid inhibitors and stimulators
BACKGROUND
Cannabinoid (CB) 2 is expressed on immune and inflammatory cells. Identification of 2-arachidonyl glycerol (2-AG) and anandamide as endogenous CB2 ligands has allowed investigations of the roles of CB2 and its endogenous ligand system in inflammatory cells. However, the roles of this
The pharmacological physiological effects of the endogenous cannabinomimetic (endocannabinoid) anandamide have been well characterized. Another endocannabinoid, 2-arachidonoyl-glycerol (2-AG), has been less-widely studied. 2-AG occurs in vertebrate and invertebrate tissues and binds to both
Anandamide (arachidonylethanolamide), isolated from the porcine brain, and 2-arachidonyl-glycerol (2-Ara-Gl), derived from the canine gut, are two recently identified putative endogenous cannabinoid receptor ligands. Both ligands have been reported to possess binding affinity for cannabinoid
Previous studies from this laboratory have demonstrated that a COX-2 metabolite of the endogenous cannabinoid, 2-arachidonyl glycerol (2-AG), inhibits IL-2 secretion in activated T cells through PPARgamma activation independent of the cannabinoid receptors, CB1/CB2. Because numerous cyclooxygenase
A substantial amount of lysophosphatidic acid (LPA) (15.66 nmol/g tissue) was found to occur in the brain isolated from rats killed in liquid nitrogen. We found that a significant portion of brain LPA was accounted for by the arachidonic acid-containing species (5.4%). We obtained evidence that both
2-Arachidonyl-glycerol (2-Ara-Gl) recently was identified as a putative endogenous ligand for cannabinoid receptor types CB1 and CB2 by competitive binding. More recent immune function assays demonstrated that 2-Ara-Gl possessed immunomodulatory activity. Because several plant-derived cannabinoids
Since the discovery of the endocannabinoid system, evidence has been progressively accumulating to suggest that 2-arachidonoylglycerol (2-AG) rather than anandamide (AEA) is the endogenous ligand for both cannabinoid (CB) receptors. Moreover, other studies have shown that another lipid molecule,
Management of levodopa-induced dyskinesias (LID) is one of the main challenges in the treatment of Parkinson's disease patients. Mechanisms involved in the appearance of these involuntary movements are not well known but modifications in the activity of different neurotransmitter pathways seem to
2-arachidonoyl-glycerol (2-AG) is an endocannabinoid that is released from postsynaptic neurons, acts retrogradely on presynaptic cannabinoid receptor CB1, and induces short- and long-term suppression of transmitter release. To understand the mechanisms of the 2-AG-mediated retrograde modulation, we
2-Arachidonoyl-glycerol (2-Ara-GI) has been isolated from various tissues and identified as an endogenous ligand for both cannabinoid receptors, CB1 and CB2. Here we report that in spleen, as in brain and gut, 2-Ara-GI is accompanied by several 2-acyl-glycerol esters, two major ones being
2-Arachidonoyl-glycerol (2-AG) and arachidonyl-ethanolamide (AEA) are endocannabinoids that have been implicated in many physiologic disorders, including obesity, metabolic syndromes, hepatic diseases, pain, neurologic disorders, and inflammation. Their immunomodulatory effects are numerous and are
BACKGROUND
Central cannabinoid systems have been implicated in appetite control through the respective hyperphagic and anorectic actions of CB1 agonists and antagonists. The motivational changes underlying these actions remain to be determined, but may involve alterations to food
OBJECTIVE
2-arachidonoyl glycerol (2-AG) is an endogenous cannabinoid with central antinociceptive properties. Its degradation is catalysed by monoacylglycerol lipase (MGL) whose activity is inhibited by URB602, a new synthetic compound. The peripheral antinociceptive effects of 2-AG and URB602 in
