The potential relevance of the endocannabinoid, 2- arachidonoylglycerol, in diffuse large B-cell lymphoma

Diffuse large B-cell lymphoma is an aggressive, genetically heterogenerous disease and the most common type of non-Hodgkin lymphoma among adults. To gain further insights into the etiology of DLBCL and to discover potential diseaserelated factors, we performed a serum lipid analysis on a subset of individuals from a population-based NHL case-control study. An untargeted mass-spectrometry-based […]

The Pharmacological Basis of Cannabis Therapy for Epilepsy

Recently, cannabis has been suggested as a potential alternative therapy for refractory epilepsy, which affects 30% of epilepsy, both adults and children, who do not respond to current medications. There is a large unmet medical need for new antiepileptics that would not interfere with normal function in patients with refractory epilepsy and conditions associated with […]

The Pharmacologic and Clinical Effects of Medical Cannabis

Cannabis, or marijuana, has been used for medicinal purposes for many years. Several types of cannabinoid medicines are available in the United States and Canada. Dronabinol (schedule III), nabilone (schedule II), and nabiximols (not U.S. Food and Drug Administration approved) are cannabis-derived pharmaceuticals. Medical cannabis or medical marijuana, a leafy plant cultivated for the production […]

The pattern of neurodegeneration in Huntington’s disease: a comparative study of cannabinoid, dopamine, adenosine and GABAa receptor alterations in the human basal ganglia in Huntington’s disease

In order to investigate the sequence and pattern of neurodegeneration in Huntington’s disease, the distribution and density of cannabinoid CB1, dopamine D1 and D2, adenosine A2a and GABAA receptor changes were studied in the basal ganglia in early (grade 0), intermediate (grades 1, 2) and advanced (grade 3) neuropathological grades of Huntington’s disease. The results […]

The orphan receptor GPR55 is a novel cannabinoid receptor

Background: The endocannabinoid system functions through two well characterized receptor systems, the CB1 and CB2 receptors. Work by a number of groups in recent years has provided evidence that the system is more complicated and additional receptor types should exist to explain ligand activity in a number of physiological processes. Experimental approach: Cells transfected with […]

The Nonpsychoactive Cannabis Constituent Cannabidiol Is a Wake-Inducing Agent

Cannabidiol (CBD) is a constituent of Cannabis sativa that induces nonpsychotropic effects, and some of its biological actions in sleep have been described by the authors’ group. Here, the authors report that when administered 10 or 20 g/1 l during the lights-on period directly into either lateral hypothalamus (LH) or dorsal raphe nuclei (DRN), which […]

The Nonpsychoactive Cannabinoid Cannabidiol Inhibits 5-Hydroxytryptamine3A Receptor-Mediated Currents in Xenopus laevis Oocytes

The effect of the plant-derived nonpsychotropic cannabinoid, cannabidiol (CBD), on the function of hydroxytryptamine (5-HT)3A receptors expressed in Xenopus laevis oocytes was investigated using two-electrode voltage-clamp techniques. CBD reversibly inhibited 5-HT (1 M)-evoked currents in a concentration-dependent manner (IC50 0.6 M). CBD (1 M) did not alter specific binding of the 5-HT3A antagonist [3 H]3-(5-methyl-1H-imidazol-4-yl)-1-(1-methylindol-3-yl)propan-1-one […]

The neuroprotective role of endocannabinoids against chemical-induced injury and other adverse effects

Considerable progress has been made, recently, in understanding the role of the endocannabinoid system in regard to neuroprotection. Endogenous cannabinoids have received increasing attention as potential protective agents in several cases of neuronal injury. The endocannabinoid system is comprised of cannabinoid receptors (CB1 and CB2), their endogenous ligands (endocannabinoids) and proteins responsible for their metabolism. […]

The influence of cannabinoids on generic traits of neurodegeneration

In an increasingly ageing population, the incidence of neurodegenerative disorders such as Alzheimer’s disease, Parkinson’s disease and Huntington’s disease are rising. While the aetiologies of these disorders are different, a number of common mechanisms that underlie their neurodegenerative components have been elucidated; namely neuroinflammation, excitotoxicity, mitochondrial dysfunction and reduced trophic support. Current therapies focus on […]

The importance of the ratio of omega-6/omega-3 essential fatty acids

Several sources of information suggest that human beings evolved on a diet with a ratio of omega-6 to omega-3 essential fatty acids (EFA) of approximately 1 whereas in Western diets the ratio is 15/1-16.7/1. Western diets are deficient in omega-3 fatty acids, and have excessive amounts of omega-6 fatty acids compared with the diet on […]
