Inflammation caused by activated macrophages and T lymphocytes may trigger plaque rapture in acute coronary syndrome (ACS). Anandamide and 2-arachidonylglycerol (2-AG) are macrophage-derived signal lipids and may be involved in the pathogenesis of ACS, but no clinical relevant data have been
Although the endocannabinoids 2-arachidonoylglycerol (2-AG) and anandamide share a similar pharmacology, 2-AG reportedly limits myocardial ischaemia-reperfusion injury whereas anandamide does not. We therefore investigated whether or not anandamide reduces infarct size and which, if any, of the
Cannabinoids, the active ingredients of Cannabis sativa, have been used by humans as hallucinogens and therapeutic agents for thousands of years. These agents are now known to act through the cannabinoid CB1 and CB2 receptors. The recent discovery of endogenous cannabinoids and the fact that they
The present study was carried out to examine whether acute experimental myocardial infarction affects the sympathetic transmission to vessels and the heart of pithed rats via a presynaptic mechanism and, if so, to check whether inhibitory presynaptic cannabinoid (CB) receptors and endocannabinoids
Endocannabinoid system is reported to be activated during myocardial ischemia-reperfusion (IR) injury and protects against heart injury. We, therefore, observed changes in endocannabinoids levels during acute myocardial infarction (AMI) and myocardial IR injury and evaluated the role of
OBJECTIVE
We sought to determine whether endocannabinoids influence hemodynamic variables in experimental models of acute myocardial infarction (MI).
BACKGROUND
Hypotension and cardiogenic shock are common complications in acute MI. Cannabinoids are strong vasodilators, and endocannabinoids are
UNASSIGNED
Myocardial infarction leads to an enhanced release of endocannabinoids and a massive accumulation of neutrophils and monocytes within the ischemic myocardium. These myeloid cells originate from hematopoietic precursors in the bone marrow and are rapidly mobilized in response to myocardial
OBJECTIVE
Cannabidiol has been reported to be a neuroprotectant, but the neuroprotective mechanism of cannabidiol remains unclear. We studied the neuroprotective mechanism of cannabidiol in 4-hour middle cerebral artery (MCA) occlusion mice.
METHODS
Male MCA occluded mice were treated with
Anandamide (AEA), one of endocannabinoids, has been reported to exhibit a cardioprotective ability to limit the damage produced by ischemia-reperfusion injury. AEA reportedly enhanced heat shock protein 72 (HSP72) and HSP25 expression in lungs to protect against lung inflammation. This study tested
The role of endocannabinoid signaling in the response of the brain to injury is tantalizing but not clear. In this study, transient middle cerebral artery occlusion (MCAo) was used to produce ischemia/reperfusion injury. Brain content of N-arachidonoylethanolamine (AEA) and 2-arachidonoylglycerol
Ethanolamine is a biogenic amine found naturally in the body as part of membrane lipids and as a metabolite of the cardioprotective substances, sphingosine-1-phosphate (S1P) and anandamide. In the brain, ethanolamine, formed from the breakdown of anandamide protects against ischaemic apoptosis.
Cannabinoids can mimic the infarct-reducing effect of early ischemic preconditioning, delayed ischemic preconditioning, and ischemic postconditioning against myocardial ischemia/reperfusion. They do this primarily through both CB1 and CB2 receptors. Cannabinoids are also involved in remote
Although cannabinoids have been recreationally employed for thousands of years, it was not until the discovery of their specific receptors, in the early nineties, that the molecular basis of cannabinoid activity have began to be understood. Growing research in this field has demonstrated not only
Traumatic brain injury (TBI) releases harmful mediators that lead to secondary damage. On the other hand, neuroprotective mediators are also released, and the balance between these classes of mediators determines the final outcome after injury. Recently, it was shown that the endogenous brain
Endogenous levels of the endocannabinoid anandamide, and the activities of the synthesizing and hydrolyzing enzymes, i.e. N-acylphosphatidylethanolamine-hydrolyzing phospholipase D and fatty acid amide hydrolase, respectively, were determined in the cortex and the striatum of rats subjected to
