The binding of a classical cannabinoid agonist, [3H]R-(+)-(2,3-dihydro-5-methyl-3-[(4-morpholinyl)methyl]pyrol[1,2 ,3-de]-1,4-benzoxazin-6-yl)(1-napthalenyl)methanone monomethanesulfonate ([3H] WIN55212-2), and a selective cannabinoid receptor (CB1) antagonist,
Solubilization of the cannabinoid receptor from rat brain and its functional interaction with guanine nucleotide-binding proteins.
Ainult registreeritud kasutajad saavad artikleid tõlkida

The present investigation was undertaken to characterize cannabinoid receptor binding in the absence of the membrane environment, inasmuch as cannabinoid drugs have been noted to influence the behavior of integral membrane proteins. The zwitterionic detergent

Intermittent ethanol exposure during adolescence impairs cannabinoid type 1 receptor-dependent long-term depression and recognition memory in adult mice.

Logi sisse
Binge drinking is a significant problem in adolescent populations, and because of the reciprocal interactions between ethanol (EtOH) consumption and the endocannabinoid (eCB) system, we sought to determine if adolescent EtOH intake altered the localization and function of the cannabinoid 1
Differential requirements of sodium for coupling of cannabinoid receptors to adenylyl cyclase in rat brain membranes.
Ainult registreeritud kasutajad saavad artikleid tõlkida
Logi sisse
Sodium is generally required for optimal inhibition of adenylyl cyclase by Gi/o-coupled receptors. Cannabinoids bind to specific receptors that act like other members of the Gi/o-coupled receptor superfamily to inhibit adenylyl cyclase. However, assay of cannabinoid inhibition of adenylyl cyclase in
Cannabis use by women during pregnancy does not influence infant DNA methylation of the dopamine receptor DRD4.

Maternal cannabis use in pregnancy is linked with long-term adverse behavioral outcomes in offspring. Epigenetic processes established in utero that affect dopaminergic (reward) signaling may mediate risks. Associations between cannabis use and offspring DNA methylation have not been investigated;
Signal transduction activated by cannabinoid receptors.

Since the discovery that cannabinoids exert biological actions through binding to specific receptors, signal mechanisms triggered by these receptors have been focus of extensive study. This review summarizes the current knowledge of the signalling events produced by cannabinoids from membrane
Differential receptor-G-protein coupling evoked by dissimilar cannabinoid receptor agonists.

Multiple affinity states are revealed by agonist competition for radioantagonist [3H]SR141716A binding to rat brain CB1 cannabinoid receptors. Desacetyllevonantradol (DALN), a tricyclic cannabinoid, and WIN55212-2, an aminoalkylindole, both bound in two discrete affinity states (30% high affinity),
Differential coupling of the human cannabinoid receptors hCB1R and hCB2R to the G-protein G(alpha)i2beta1gamma2.

Logi sisse
Human cannabinoid receptors 1 (hCB(1)R) and 2 (hCB(2)R) are expressed in the CNS and couple to G(i)/G(o)-proteins. The aim of this study was to compare coupling of hCB(1)R and hCB(2)R to G(alpha)(i2)beta(1)gamma(2) in Sf9 insect cells. High-affinity agonist binding at hCB(1)R, but not at hCB(2)R,

In the present study, we showed that Chinese hamster ovary (CHO) cells transfected with human central cannabinoid receptor (CB1) exhibit high constitutive activity at both levels of mitogen-activated protein kinase (MAPK) and adenylyl cyclase. These activities could be blocked by the CB1-selective

We investigated the role of the Ras/extracellular-regulated kinase (ERK) pathway in the development of tolerance to Delta(9)-tetrahydrocannabinol (THC)-induced reduction in spontaneous locomotor activity by a genetic (Ras-specific guanine nucleotide exchange factor (Ras-GRF1) knock-out mice) and
Cannabinoid receptor-interacting protein 1a modulates CB1 receptor signaling and regulation.

Cannabinoid CB1 receptors (CB1Rs) mediate the presynaptic effects of endocannabinoids in the central nervous system (CNS) and most behavioral effects of exogenous cannabinoids. Cannabinoid receptor-interacting protein 1a (CRIP1a) binds to the CB1R C-terminus and can attenuate constitutive

Extensive behavioral and biochemical characterization of cannabinoid-mediated effects on the central nervous system has revealed at least three lines of evidence supporting the role of a putative guanine nucleotide-binding protein-coupled cannabinoid receptor for cannabimimetic effects, (i)
