Background CB1 and CB2 cannabinoid receptors are G protein-coupled receptors which have been described to couple mainly to the Gi/o subfamily of G proteins. However, in some cell types and upon stimulation with certain cannabinoid agonists, activation of other G protein subtypes has also been observed. GPR55 is an orphan G protein-coupled receptor which has been suggested to be a novel member o...
This study examined the photoperiodic regulation of energy balance and cannabinoid receptor expression in the Siberian hamster (Phodopus sungorus) hypothalamus. Short day lengths, beginning at weaning, reduced food intake, body mass and fat pad masses and also decreased cannabinoid receptor immunostaining in the anterior and lateral hypothalamic nuclei of male hamsters. These data suggest a pot...
AIM We hypothesized that the anticancer activity of cannabinoids was linked to induction of phosphatases. MATERIALS AND METHODS The effects of cannabidiol (CBD) and the synthetic cannabinoid WIN-55,212 (WIN) on LNCaP (prostate) and SW480 (colon) cancer cell proliferation were determined by cell counting; apoptosis was determined by cleavage of poly(ADP)ribose polymerase (PARP) and caspase-3 (...
The human cannabinoid receptors, central cannabinoid receptor (CB1) and peripheral cannabinoid receptor (CB2), share only 44% amino acid identity overall, yet most ligands do not discriminate between receptor subtypes. Site-directed mutagenesis was employed as a means of mapping the ligand recognition site for the human CB2 cannabinoid receptor. A lysine residue in the third transmembrane domai...
(-)-Delta9-Tetrahydrocannabinol ((-)-Delta9-THC) is the major active psychotropic component of the marijuana plant, Cannabis sativa. The membrane proteins that have been found to bind this material or its derivatives have been called the cannabinoid receptors. Two GTP-binding protein-coupled cannabinoid receptors have been cloned. CB1 or the neuronal cannabinoid receptor is found mostly in neur...
Ten years elapsed since the discovery by Sanofi of SR141716A the first selective CB(1) cannabinoid receptor antagonist. Shortly after, Sanofi also reported the synthesis of the first selective CB(2) cannabinoid receptor antagonist, SR144528. Since these two milestones in the cannabinoid field, many other compounds, more or less related to the Sanofi compounds, or based on a completely different...
Endocannabinoids act as neuromodulatory and neuroprotective cues by engaging type 1 cannabinoid receptors. These receptors are highly abundant in the basal ganglia and play a pivotal role in the control of motor behaviour. An early downregulation of type 1 cannabinoid receptors has been documented in the basal ganglia of patients with Huntington's disease and animal models. However, the pathoph...
The cannabinoid receptors, CB1 and CB2, are members of the G-protein coupled receptor family and share many of this family's structural features. A highly conserved aspartic acid residue in the second transmembrane domain of G-protein coupled receptors has been shown for many of these receptors to be functionally important for agonist binding and/or G-protein coupling. To determine whether this...
Given the vast therapeutic potential of the endocannabinoid system, the revelation of a novel cannabinoid-sensitive target was treated with great excitement. The orphan G-protein coupled receptor 55 (GPR55) was initially touted as a novel cannabinoid target in early industrial patent literature. Consequently, numerous studies have revealed GPR55 expression in a diverse array of cells and tissue...
