The experiments presented in this paper examine the mechanisms underlying the ability of cannabinoids to alter the in vivo levels of cyclic adenosine 3',5'-monophosphate (cyclic AMP) in mouse brain. It was found that changes in cyclic AMP levels are a composite result of direct actions of
Several lines of evidence imply early alterations in endocannabinoid and phosphodiesterase 10A (PDE10A) signaling in Huntington disease (HD). Using [(18)F]MK-9470 and [(18)F]JNJ42259152 small-animal positron emission tomography (PET), we investigated for the first time cerebral changes in type 1
Rat testis was shown to contain significant amounts of both N-acylethanolamine, including N-arachidonoylethanolamine (anandamide), and N-acylphosphatidylethanolamine (N-acylPE), including N-arachidonoylPE. The fatty acid profiles of the N-acyl moieties of the two classes resembled each other. We
The levels of N-arachidonoylethanolamine (anandamide), an endogenous cannabinoid-receptor ligand, and a relevant molecule, N-arachidonoylphosphatidylethanolamine (N-arachidonoylPtdEtn), in rat brain were investigated using a newly developed sensitive analytical method. We found that rat brain
The recreational use of drugs of abuse associated to therapeutically used drugs in sexual contexts forces the health care professional to know the possibility of drug-drug interactions among them. The aim of this review is updating the available information on cardiovascular safety of It is well known that the cannabinoid system has a significant role in the regulation of the immune responses. Cannabinoid receptors CB1 and CB2 are expressed on T lymphocytes and mediate the immunomodulatory effects of cannabinoids on T cell functions. Here we show that the treatment of proteolipid
This review presents and explores the hypothesis that N-arachidonylethanolamine (AEA, also called anandamide) is synthesized in the brain and functions as an endogenous ligand of the cannabinoid receptor. Support for this hypothesis comes from in vitro experiments demonstrating that AEA binds and
OBJECTIVE
Different types of insults to the CNS lead to axon demyelination. Remyelination occurs when the CNS attempts to recover from myelin loss and requires the activation of oligodendrocyte precursor cells. With the rationale that CB1 receptor is expressed in oligodendrocytes and marijuana
Antinociception caused by cannabinoids may have a partial peripheral origin in addition to its central site of action. In fact, we have observed that anandamide selectively and reversibly inhibits GABAA receptors of putative nociceptive neurons of mouse trigeminal sensory ganglia via CB1
Previous studies have shown that cannabinoid receptor analogs increase voltage-dependent potassium A-current (IA) in cultured hippocampal cells. Because cannabinoid receptors inhibit adenylate cyclase, the present study explored whether cAMP played a role in mediating this effect on IA. The specific
Understanding the mechanisms involved in the biogenesis of N-arachidonoylethanolamine (anandamide) and N-palmitoylethanolamine is important in view of the possible role of these lipids as endogenous cannabinoid substances. Anandamide (which activates cannabinoid CB1 receptors) and
Anandamide (N-arachidonoyl-ethanolamine) was recently identified as a brain arachidonate derivative that binds to and activates cannabinoid receptors, yet the mechanisms underlying formation, release and inactivation of this putative messenger molecule are still unclear. Here we report that
Recent studies have addressed the changes in endocannabinoid ligands and receptors that occur in multiple sclerosis, as a way to explain the efficacy of cannabinoid compounds to alleviate spasticity, pain, tremor, and other signs of this autoimmune disease. Using Lewis rats with experimental
The psychoactive properties of Cannabis sativa and its major biologically active constituent, delta 9-tetrahydrocannabinol, have been known for years. The recent identification and cloning of a specific cannabinoid receptor suggest that cannabinoids mimic endogenous compounds affecting neural
This study was undertaken to ascertain the effects of cannabinoid drugs on prostanoid-stimulated adenylate cyclase in neuroblastoma cells. This report demonstrates that delta 9-tetrahydrocannabinol (THC) and levonantradol could decrease initial rate cyclic AMP accumulation in response to
