The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.

The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

A critical role for the cannabinoid CB1 receptors in alcohol dependence and stress-stimulated ethanol drinking. (1/1474)

Although many people drink alcohol regularly, only some become addicted. Several studies have shown that genetic and environmental factors contribute to individual differences in the vulnerability to the effects of alcohol (Nestler, 2000; Kreek, 2001; Crabbe, 2002). Among the environmental factors, stress is perhaps the most important trigger for relapse after a period of abstinence (Koob and Nestler, 1997; Piazza and Le Moal, 1998; Koob and Le Moal, 2001; Weiss et al., 2001). Here we show that ethanol withdrawal symptoms were completely absent in cannabinoid CB1 receptor-deficient mice, although acute effects of ethanol and ethanol tolerance and preference were basically normal. Furthermore, foot-shock stress had no affect on alcohol preference in Cnr1-/- mice, although it induced a dramatic increase in Cnr1+/+ animals. These results reveal a critical role for the CB1 receptor in clinically important aspects of alcohol dependence and provide a rationale for the use of CB1 receptor antagonists in the treatment of alcohol addiction.  (+info)

Cannabinoid CB(1) receptor-mediated inhibition of hippocampal acetylcholine release is preserved in aged mice. (2/1474)

1. The cannabinoid CB(1) receptor inverse agonist/antagonist SR 141716 increases acetylcholine release in rodent hippocampus and improves memory in some experimental paradigms. Since drugs like SR 141716 may represent a novel class of cognition-enhancing drugs, we wanted to check whether the function of the CB(1) receptor is preserved during ageing. 2. Hippocampal and striatal slices from 2- to 3- and 24- to 28-month-old C57BL/6J mice were preincubated with [(3)H]-choline or [(3)H]-noradrenaline ([(3)H]-NA) and superfused. 3. The cannabinoid receptor agonist WIN 55212-2 inhibited, and SR 141716 facilitated, the electrically (3 Hz) evoked tritium overflow in hippocampal slices (preincubated with [(3)H]-choline) from young and aged mice to the same extent. The evoked overflow per se was less by 33% in slices from aged animals. 4. WIN 55212-2 and SR 141716 did not affect, but the muscarinic receptor agonist oxotremorine inhibited, the evoked (3 Hz) overflow in striatal slices (preincubated with [(3)H]-choline) from young and aged mice to the same extent. The evoked overflow per se tended to be less in slices from aged animals. 5. The evoked (0.3 Hz) overflow in hippocampal slices (preincubated with [(3)H]-NA) was not affected by WIN 55212-2 and SR 141716, but was inhibited by histamine (via H(3) receptors) in slices from young mice and, to a somewhat less extent, in slices from aged mice. The evoked overflow per se did not differ between age groups. 6. In conclusion, the function of the CB(1) receptor involved in the tonic inhibition of hippocampal acetylcholine release is preserved in aged mice.  (+info)

A3 adenosine and CB1 receptors activate a PKC-sensitive Cl- current in human nonpigmented ciliary epithelial cells via a G beta gamma-coupled MAPK signaling pathway. (3/1474)

(1) We examined A3 adenosine and CB1 cannabinoid receptor-coupled signaling pathways regulating Cl(-) current in a human nonpigmented ciliary epithelial (NPCE) cell line. (2) Whole-cell patch-clamp recordings demonstrated that the A3 receptor agonist, IB-MECA, activates an outwardly rectifying Cl(-)current (I(Cl,Aden)) in NPCE cells, which was inhibited by the adenosine receptor antagonist, CGS-15943 or by the protein kinase C (PKC) activator, phorbol 12,13 dibutyrate (PDBu). (3) Treatment of NPCE cells with pertussis-toxin (PTX), or transfection with the COOH-terminus of beta-adrenergic receptor kinase (ct-betaARK), inhibited I(Cl,Aden). The phosphatidyl inositol 3-kinase (PI3K) inhibitor, wortmannin, had no effect on I(Cl,Aden); however, the mitogen-activated protein kinase kinase (MEK) inhibitor, PD98059, inhibited I(Cl,Aden). (4) Reverse transcription-polymerase chain reaction experiments and immunocytochemistry confirmed mRNA and protein expression for the CB1 receptor in NPCE cells, and the CB1 receptor agonist, Win 55,212-2, activated a PDBu-sensitive Cl(-) current (I(Cl,Win)). (5) Transfection of NPCE cells with the human CB1 (hCB1) receptor, increased I(Cl,Win), consistent with increased receptor expression, and I(Cl,Win) in hCB1 receptor-transfected cells was decreased after application of a CB1 receptor inverse agonist, SR 141716. (6) Constitutive activity for CB1 receptors was not significant in NPCE cells as transfection with hCB1 receptors did not increase basal Cl(-) current, nor was basal current inhibited by SR 141716. (7) I(Cl,Win) was inhibited by PTX preincubation, by transfection with ct-betaARK and by the MEK inhibitor, PD98059, but unaffected by the PI3K inhibitor, wortmannin. (8) We conclude that both A3 and CB1 receptors activate a PKC-sensitive Cl(-) current in human NPCE cells via a G(i/o)/Gbetagamma signaling pathway, in a manner independent of PI3K but involving MAPK.  (+info)

Reduction of human monocytic cell neurotoxicity and cytokine secretion by ligands of the cannabinoid-type CB2 receptor. (4/1474)

1 Two cannabinoid receptors, CB1 and CB2, have been identified. The CB1 receptor is preferentially expressed in brain, and the CB2 receptor in cells of leukocyte lineage. We identified the mRNA for the CB1 receptor in human neuroblastoma SH-SY5Y cells, and the mRNA and protein for the CB2 receptor in human microglia and THP-1 cells. 2 Delta(9)-and Delta(8)-tetrahydrocannabinol (THC) were toxic when added directly to SH-SY5Y neuroblastoma cells. The toxicity of Delta(9)- THC was inhibited by the CB1 receptor antagonist SR141716A but not by the CB2 receptor antagonist SR144528. The endogenous ligand anandamide was also toxic, and this toxicity was enhanced by inhibitors of its enzymatic hydrolysis. 3 The selective CB2 receptor ligands JWH-015 and indomethacin morpholinylamide (BML-190), when added to THP-1 cells before stimulation with lipopolysaccharide (LPS) and IFN-gamma, reduced the toxicity of their culture supernatants to SH-SY5Y cells. JWH-015 was more effective against neurotoxicity of human microglia than THP-1 cells. The antineurotoxic activity of JWH-015 was blocked by the selective CB2 receptor antagonist SR144528, but not by the CB1 receptor antagonist SR141716A. This activity of JWH-015 was synergistic with that of the 5-lipoxygenase (5-LOX) inhibitor REV 5901. 4 Cannabinoids inhibited secretion of IL-1beta and tumor necrosis factor-alpha (TNF-alpha) by stimulated THP-1 cells, but these effects could not be directly correlated with their antineurotoxic activity. 5 Specific CB2 receptor ligands could be useful anti-inflammatory agents, while avoiding the neurotoxic and psychoactive effects of CB1 receptor ligands such as Delta(9)-THC.  (+info)

Cannabinoid1 receptor in the dorsal vagal complex modulates lower oesophageal sphincter relaxation in ferrets. (5/1474)

Delta9-tetrahydrocannabinol (delta9-THC) is an effective anti-emetic; however, other potential gastrointestinal therapeutic effects of delta9-THC are less well-known. Here, we report a role of delta9-THC in a vago-vagal reflex that can result in gastro-oesophageal reflux, that is, gastric distension-evoked lower oesophageal sphincter (LOS) relaxation. Oesophageal, LOS and gastric pressures were measured using a miniaturized, manometric assembly in decerebrate, unanaesthetized ferrets.Gastric distension (30 ml) evoked LOS relaxation (70 +/- 8% decrease from baseline). Delta9-THC administered systemically (0.2 mg kg-1, iv.) or directly to the dorsal hindbrain surface (0.002 mg),significantly attenuated the nadir of the gastric distention-evoked LOS relaxation, and time to reach maximal response. Similar increases to maximal effect were observed after treatment with the cannabinoid receptor agonist WIN 55,212-2 (0.2 mg kg-1 iv.). The effect of systemic delta9-THC on gastric distention-evoked LOS relaxation was reversed by a selective cannabinoid1 (CBI) receptor antagonist, SR141617A (1 mg kg-1 i.v.). Since this reflex is vagally mediated, we used a CB1 receptor antiserum and immunocytochemistry to determine its distribution in ferret vagal circuitry. CBI receptor staining was present in cell bodies within the area postrema, nucleus tractus solitarius (NTS) and nodose ganglion. Intense terminal-like staining was noted within the NTS and dorsal motor vagal nucleus (DMN). Neither nodose ganglionectomy nor vagotomy altered the CB1 receptor terminal-like staining in the dorsal vagal complex. Retrogradely labelled gastric- or LOS-projecting DMN neurones did not express CBI receptors within their soma. Therefore, CBI receptor staining in the NTS and DMN is not due to primary vagal afferents or preganglionic neurones. These novel findings suggest that delta9-THC can modulate reflex LOS function and that the most likely site of action is via the CBI receptor within the NTS. This effect of delta9-THC may have implications in treatment of gastro-oesophageal reflux and other upper gut disorders.  (+info)

Cannabinoid receptor type 1 modulates excitatory and inhibitory neurotransmission in mouse colon. (6/1474)

The effects of cannabinoid receptor agonists and antagonists on smooth muscle resting membrane potentials and on membrane potentials following electrical neuronal stimulation in a myenteric neuron/smooth muscle preparation of wild-type and cannabinoid receptor type 1 (CB1)-deficient mice were investigated in vitro. Double staining for CB1 and nitric oxide synthase (neuronal) was performed to identify the myenteric CB1-expressing neurons. Focal electrical stimulation of the myenteric plexus induced a fast (f) excitatory junction potential (EJP) followed by a fast and a slow (s) inhibitory junction potential (IJP). Treatment of wild-type mice with the endogenous CB1 receptor agonist anandamide reduced EJP while not affecting fIJP and sIJP. EJP was significantly higher in CB1-deficient mice than in wild-type littermate controls, and anandamide induced no effects in CB1-deficient mice. N-arachidonoyl ethanolamide (anandamide), R-[2,3-dihydro-5-methyl-3-(4-morpholinylmethyl)pyrrolo[1,2,3,-de]- 1,4-benzoxazin-6-yl]-1-naphtalenylmethanone, a synthetic CB1 receptor agonist, nearly abolished EJP and significantly reduced the fIJP in wild-type mice. N-piperidino-5-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-4-methyl-3-pyrazole-caroxa mide (SR141716A), a CB1-specific receptor antagonist, was able to reverse the agonist effects induced in wild-type mice. SR141716A, when given alone, significantly increased EJP in wild-type mice without affecting IJP in wild-type and EJP in CB1-deficient mice. Interestingly, SR141716A reduced fIJP in CB1-deficient mice. In the mouse colon, nitrergic myenteric neurons do not express CB1, implying that CB1 is expressed in cholinergic neurons, which is in line with the functional data. Finally, excitatory and inhibitory neurotransmission in the mouse colon is modulated by activation of CB1 receptors. The significant increase in EJP in CB1-deficient mice strongly suggests a physiological involvement of CB1 in excitatory cholinergic neurotransmission.  (+info)

Toxicological and structural features of organophosphorus and organosulfur cannabinoid CB1 receptor ligands. (7/1474)

Potent cannabinoid CB1 receptor ligands include anandamide [N-(2-hydroxyethyl)arachidonamide], Delta9-tetrahydrocannabinol, and 3H-CP 55,940 at the agonist site and selected organophosphorus esters (including some pesticides) and organosulfur compounds at a proposed closely coupled "nucleophilic" site. This study considers the toxicological and structural features of alkylfluorophosphonates, benzodioxaphosphorin oxides, alkanesulfonyl fluorides, and analogs acting at the nucleophilic site. Binding at the agonist site, using3H-CP 55,940 in assays with mouse brain membranes, is inhibited byO-isopropyl dodecylfluorophosphonate (compound 2), dodecanesulfonyl fluoride (compound 14) and dodecylbenzodioxaphosphorin oxide with IC50 values of 2-11 nM. Compounds 2 and 14 are also effectivein vivo, with 84% inhibition of mouse brain CB1 binding 4 h after intraperitoneal dosage at 30 mg/kg. Compound 14-inhibited CB1 in mouse brain requires about 3-4 days for recovery of 50% activity, suggesting covalent derivatization. Delayed toxicity (mortality in 0.3-5 days) from compounds 2, 14, and octanesulfonyl fluoride (18) is more closely associated with in vivo inhibition of brain neuropathy target esterase-lysophospholipase (NTE-LysoPLA) than with that of CB1 or acetylcholinesterase. NTE-LysoPLA inhibited by sulfonyl fluorides 14 and 18 cannot "age," a proposed requirement for NTE phosphorylated by organophosphorus-delayed neurotoxicants. Several octane- and dodecanesulfonamides with N-(2-hydroxyethyl) and other substituents based on anandamide give depressed mobility and recumbent posture in mice, but the effects do not correlate with potency for CB1 inhibition in vitro. Specific toxicological responses are not clearly associated with organophosphorus- or organosulfur-induced inhibition of the proposed CB1 nucleophilic site in mouse brain. On the other hand, the most potent CB1 inhibitors examined here are also NTE-LysoPLA inhibitors and cause delayed toxicity in mice.  (+info)

The cannabinoid system and immune modulation. (8/1474)

Studies on the effects of marijuana smoking have evolved into the discovery and description of the endocannabinoid system. To date, this system is composed of two receptors, CB1 and CB2, and endogenous ligands including anandamide, 2-arachidonoyl glycerol, and others. CB1 receptors and ligands are found in the brain as well as immune and other peripheral tissues. Conversely, CB2 receptors and ligands are found primarily in the periphery, especially in immune cells. Cannabinoid receptors are G protein-coupled receptors, and they have been linked to signaling pathways and gene activities in common with this receptor family. In addition, cannabinoids have been shown to modulate a variety of immune cell functions in humans and animals and more recently, have been shown to modulate T helper cell development, chemotaxis, and tumor development. Many of these drug effects occur through cannabinoid receptor signaling mechanisms and the modulation of cytokines and other gene products. It appears the immunocannabinoid system is involved in regulating the brain-immune axis and might be exploited in future therapies for chronic diseases and immune deficiency.  (+info)

The cannabinoid receptor type 2, abbreviated as CB2, is a G protein-coupled receptor from the cannabinoid receptor family that in humans is encoded by the CNR2 gene. It is closely related to the cannabinoid receptor type 1, which is largely responsible for the efficacy of endocannabinoid-mediated presynaptic-inhibition, the psychoactive properties of tetrahydrocannabinol, the active agent in cannabis, and other phytocannabinoids (plant cannabinoids). The principal endogenous ligand for the CB2 receptor is 2-arachidonoylglycerol (2-AG). CB2 was cloned in 1993 by a research group from Cambridge looking for a second cannabinoid receptor that could explain the pharmacological properties of tetrahydrocannabinol. The receptor was identified among cDNAs based on its similarity in amino-acid sequence to the cannabinoid receptor type 1 (CB1) receptor, discovered in 1990. The discovery of this receptor helped provide a molecular explanation for the established effects of cannabinoids on the immune system. ...
We document in vitro and in vivo effects of a novel, selective cannabinoid CB(1) receptor inverse agonist, Imidazole 24b (5-(4-chlorophenyl)-N-cyclohexyl-4-(2,4-dichlorophenyl)-1-methyl-imidazole-2-carboxamide). The in vitro binding affinity of Imidazole 24b for recombinant human and rat CB(1) receptor is 4 and 10 nM, respectively. Imidazole 24b binds to human cannabinoid CB(2) receptor with an affinity of 297 nM; in vitro, it is a receptor inverse agonist at both cannabinoid CB(1) and CB(2) receptors as it causes a further increase of forskolin-induced cAMP increase. Oral administration of Imidazole 24b blocked CP-55940-induced hypothermia, demonstrating cannabinoid CB(1) receptor antagonist efficacy in vivo. Using ex vivo autoradiography, Imidazole 24b resulted in dose-dependent increases in brain cannabinoid CB(1) receptor occupancy (RO) at 2h post-dosing in rats, indicating that approximately 50% receptor occupancy is sufficient for attenuation of receptor agonist-induced hypothermia. ...
The endocannabinoid system regulates food intake, energy, and glucose metabolism at both central and peripheral levels. We have investigated the mechanism by which it may control glucose uptake in skeletal muscle cells. Detectable levels of the cannabinoid receptor type 1 (CB1) were revealed in L6 cells. Exposure of differentiated L6 myotubes to the CB1 antagonist rimonabant (SR141716) selectively increased 2-deoxyglucose uptake (2-DG) in a time- and dose-dependent manner. A similar effect was induced by genetic silencing of CB1 by small interfering RNA. Protein expression profiling revealed that both the regulatory p85 and the catalytic p110 subunits of the phosphatidylinositol-3-kinase (PI3K) were increased by SR141716. No significant change in the cellular content of other known molecules regulating PI3K was observed. However, phosphoinositide-dependent kinase-1, Akt/protein kinase B, and protein kinase Cζ activities were rapidly induced after SR141716 treatment of L6 cells in a ...
The endocannabinoid system possesses neuromodulatory functions by influencing the release of various neurotransmitters, including γ-aminobutyric acid (GABA) and glutamate. A functional interaction between endocannabinoids and the serotonergic system has already been suggested. Previously, we showed that cannabinoid type 1 (CB1) receptor mRNA and protein are localized in serotonergic neurons of the raphe nuclei, implying that the endocannabinoid system can modulate serotonergic functions. In order to substantiate the physiological role of the CB1 receptor in serotonergic neurons of the raphe nuclei, we generated serotonergic (5-HT) neuron-specific CB1 receptor-deficient mice, using the Cre/loxP system with a tamoxifen-inducible Cre recombinase under the control of the regulatory sequences of the tryptophan hydroxylase 2 gene (TPH2-CreERT2), thus, restricting the recombination to 5-HT neurons of the central nervous system. Applying several different behavioral paradigms, we revealed that mice lacking the

Abstract: The endocannabinoid system has been historically targeted for medicinal purposes through the use of cannabis. Two cannabinoid receptors, CB1 and CB2, have been identified as the mediators of the biological effects of the main psychoactive component in Cannabis sativa; delta-9-tetrahydrocannabinol. The CB1 receptor is a class A G-protein coupled receptor (GPCR), and is the most abundant neuro-modulatory receptor in the CNS. With its location at presynaptic termini, it regulates the function of other receptors, including the dopamine, serotonin, GABA, opioid and glutamate receptors. Many potential therapeutic applications targeting the CB1 receptor are under investigation. However, the unformed knowledge in drug-receptor interactions at the molecular level, and in the CB1 receptor signaling properties, has hampered the transition of many synthesized CB1 receptor agonists and antagonists to clinical use. In the studies to be presented, computational and mutational methods are employed to ...

TY - JOUR. T1 - CB1 cannabinoid receptor induction in experimental stroke. AU - Jin, Kun Lin. AU - Mao, Xiao Ou. AU - Goldsmith, Paul C.. AU - Greenberg, David A.. PY - 2000. Y1 - 2000. N2 - Cannabinoids protect cortical neurons from ischemic injury by interacting with CB1 receptors. Because a variety of neuroprotective genes are induced in cerebral ischemia, we examined the effect of experimental stroke, produced by 20 minutes of middle cerebral artery occlusion in rats, on CB1 receptor expression. Western blotting and immunohistochemistry showed that CB1 expression on neurons was increased in the arterial boundary zone of the cortical mantle, beginning by 2 hours and persisting for 72 hours or more after ischemia. These findings are consistent with a neuroprotective role for endogenous cannabinoid signaling pathways and with a potential therapeutic role in stroke for drugs that activate CB1 receptors..

CB(1) receptors were labelled on living neurons using a polyclonal antibody directed against the N-terminal 77 amino acid residues of the rat cloned CB(1) receptor. Highly punctate CB(1) receptor labelling was observed on fine axons and at axonal growth cones, with little somatic labelling. The majority of ...
© 2014 The Authors. The cannabinoid receptor 2 (CB2R) has been linked with the regulation of inflammation, and selective receptor activation has been proposed as a target for the treatment of a range of inflammatory diseases such as atherosclerosis and arthritis. In order to identify selective CB2R agonists with appropriate physicochemical and ADME properties for future evaluation in vivo, we first performed a ligand-based virtual screen. Subsequent medicinal chemistry optimisation studies led to the identification of a new class of selective CB2R agonists. Several examples showed high levels of activity (EC50 <200nM) and binding affinity (K i <200nM) for the CB2R, and no detectable activity at the CB1R. The most promising example, DIAS2, also showed favourable in vitro metabolic stability and absorption properties along with a clean selectivity profile when evaluated against a panel of GPCRs and kinases.

Cannabinoid agonists, including marijuana containing delta-9-tetrahydrocannabinol (THC), are found rewarding by humans. In addition to human self-reports and experimental studies that show marijuana is rewarding, contributions from preclinical studies also have implicated cannabinoid receptors in reward-motivated behavior. One way to assess these preclinical effects of cannabinoids is intracranial self-stimulation (ICSS), where an animal performs a response to receive electrical stimulation of a specific brain area or circuit known to be involved in reward. Drugs of abuse, such as psychomotor stimulants, facilitate responding for ICSS. While a few studies have shown facilitating effects of cannabinoids in rats, several have shown the opposite effect, and no studies so far have evaluated cannabinoids in mouse ICSS. Furthermore there are no studies evaluating specific inhibitors of endocannabinoid catabolic enzymes in ICSS in any species. In these studies we assessed the cannabinoid agonist THC, as well
With Sativex approved in a number of countries and expected to find approval in many more in the coming months, the concept of cannabinoid medicine has been proved as more than a kooky herbal remedy. The Sativex approval has validated the platform; it says you can make a medicine out of these materials and in this way. So big pharma have said, Fine, thats great; now we understand. I think that you will find a lot more interest in the cannabinoid system now that Sativex has been approved.. So what is the current state of cannabinoid research? As the head of one of the worlds leading cannabinoid research groups, Guy is well-positioned to comment. One of his fundamental tasks is to debunk the myths and preconceptions about this emerging area of science. We have to take more care to provide far more fundamental data than if wed just invented a molecule and said, Look, this is what it does, please accept it. So there is an education process. And its very cultural, very different throughout ...
Background: In prostate cancer, tumour expression of cannabinoid CB1 receptors is associated with a poor prognosis. One explanation for this association comes from experiments with transfected astrocytoma cells, where a high CB receptor expression recruits the Akt signalling survival pathway. In the present study, we have investigated the association between CB1 receptor expression and the Akt pathway in a well-characterised prostate cancer tissue microarray.. Methodology/Principal Findings: Phosphorylated Akt immunoreactivity (pAkt-IR) scores were available in the database. CB1 receptor immunoreactivity (CB1IR) was rescored from previously published data using the same scale as pAkt-IR. There was a highly significant correlation between CB1IR and pAkt-IR. Further, cases with high expression levels of both biomarkers were much more likely to have a more severe form of the disease at diagnosis than those with low expression levels. The two biomarkers had additive effects, rather than an ...
Cannabinoids bind the cannabinoid receptors CB1 and CB2, expressed both in the central nervous system as well as in the periphery. The affinity to the receptors varies between the cannabinoid and while some may bind CB1 or CB2, others have the affinity to bind both. Furthermore, some of the cannabinoids act as agonists to the receptor while others exert antagonistic effects. The endogenous ligands of the receptors (endocannabinoids) are lipophilic signaling molecules, similar to the phytocannabinoids.. CB receptors are G-coupled receptors leading to decreased levels of cyclic AMP and thus to an inhibitory effect. They have been shown to possess a role in various physiological and pathological processes. Thus, the endocannabinoid system participate in neurotransmission, neurogenesis, modulation of insulin metabolism, proliferation and immune system modulation. However, it has been shown that cannabinoids exert some of their effects via a non CB receptor dependent mechanism.. ...

Liver fibrosis, a major contributor to liver-related mortality with lack of effective treatment. It is associated with increased activity of the CB1R system, and the CB1R antagonist rimonabant mitigates fibrosis in animal models. However, the antifibrotic efficacy is low, and neuropsychiatric side effects halted its therapeutic development. Liver fibrosis is also associated with increased activity of iNOS, and iNOS inhibitors have been shown to mitigate liver fibrosis. In order to improve the safety and antifibrotic efficacy of CB1R antagonism, we have developed highly potent, orally bioavailable hybrid CB1R antagonists that are behaviorally inactive due to low brain penetrance, and have additional activity as iNOS inhibitors. We have tested the antifibrotic efficacy of the compound in a liver fibrosis induced by bile-duct ligation (BDL). (-)-MRI1867 (CB1R antagonist/iNOS inhibitor) selectively block peripheral CB1R (Ki 2.5 nM) due to its low brain penetrance. (-)-MRI1867 directly inhibits iNOS ...

Cannabinoid-1 receptors (CB1R) exist primarily on central and peripheral neurons, where activation of these receptors is associated with regulation of neurotransmitter release.. Cannabinoid-2 receptors (CB2R) are found mainly on immune cells and in selected areas of the nervous system. Drugs targeting these receptors have been demonstrated to have anti-inflammatory actions.. Cannabinoid receptors, endocannabinoids and biosynthetic and degradative enzymes for these endogenous ligands form the endocannabinoid sytem. This important biological system is upregulated during sepsis, suggesting that drugs that modulate the endocannabinoid system may represent a therapeutic target in the treatment of local and systemic inflammation associated with sepsis.. However, to date, experimental studies involving CB1R and CB2R ligands in models of sepsis have been contradictory and it is unclear whether cannabinoids mediate pro- or anti- inflammatory actions, or what the contribution of individual cannabinoid ...

Cannabinoid/Terpene Profile. Cannabinoid profiling during the growing stage enables the identification of plants that might have unique cannabinoid profiles of interest. These plants can provide growers with differentiated products and a competitive advantage in the market. Performing an analysis of compounds like cannabidiolic acid (CBDA) while a plant is still growing provides useful information for the optimization of growing conditions. Terpene profiling is also important as terpenes are primarily responsible for the taste and smell of cannabis. A terpene profile will provide further data in developing differentiated strains or products with optimum organoleptic qualities.. ...

Cannabinoids have long been known to have potent psychotropic actions, but their wide-ranging effects on the cardiovascular system are just beginning to be unraveled.. In anesthetized rat models, intravenously administered anandamide produces a triphasic hemodynamic response (28): a brief period of vagally mediated bradycardia and hypotension, followed by a transitory pressor reaction, and a relatively prolonged vasodepressor response. The latter is the dominant effect of anandamide in animal models, and it results from CB1-mediated inhibition of norepinephrine release from presynaptic nerve terminals (29). In humans, acute administration of the cannabinoids produces vasodilation and tachycardia with a variable net effect on systemic blood pressure (30), but long-term use of THC results in CB1-mediated hypotension and bradycardia (31,32).. Although CB1receptors are mostly expressed on the neuronal terminals, there is evidence showing that other cell types express these receptors and participate ...
The cannabinoid 1 receptor (CB1R) is one of the most abundant G protein-coupled receptors (GPCRs) in the central nervous system. CB1R involvement in multiple physiological processes, especially neurotransmitter release and synaptic function, has made this GPCR a prime drug discovery target, and pharmacological CB1R activation has been demonstrated to be a tenable therapeutic modality. Accordingly, the design and profiling of novel, drug-like CB1R modulators to inform the receptors ligand-interaction landscape and molecular pharmacology constitute a prime contemporary research focus. For this purpose, we report utilization of AM3677, a designer endocannabinoid (anandamide) analogue derivatized with a reactive electrophilic isothiocyanate functionality, as a covalent, CB1R-selective chemical probe. The data demonstrate that reaction of AM3677 with a cysteine residue in transmembrane helix 6 of human CB1R (hCB1R), C6.47(355), is a key feature of AM3677s ligand-binding motif. Pharmacologically, ...

α-Pinene is a monoterpene found in conifers and believed to enhance memory (Perry et al., 2000). α-Pinene did alter neurotransmission, but like limonene, it did reduced CB1 signaling (F(6,84)=3.198, P=0.0071).. Discussion. Terpenoids are cannabinoid-associated terpenes that are continuing to find their way into consumer interests due to their often-claimed therapeutic benefits, though there is little understanding of their actual effects on cannabinoid signaling. We tested several of the more widely promoted terpenes: myrcene, linalool, limonene, α-pinene, and nerolidol in a well-characterized neuronal model that utilizes endogenous cannabinoid signaling. Our chief findings are that most terpenoids either had no effect, or a modest inhibitory effect on cannabinoid signaling at 1μM. The exception was nerolidol, which had dual, opposing effects. Nerolidol reduced cannabinoid signaling, likely by inhibiting endocannabinoid synthesis, but also enhanced maximal CB1 signaling. This suggests that ...

4-cyano-1-(2,4-dichlorophenyl)-5-(4-methoxyphenyl)-N-(piperidin-1-yl)-1H-pyrazole-3-carboxamide: a CB1 cannabinoid receptor radioligand for PET imaging
Mol Med Rep 12: [Related article:] 7963-7970, 2015; DOI: 10.3892/mmr.2015.4477. Following the publication of this article, an interested reader drew to our attention an anomaly associated with the presentation of Fig. 4B. The images captured at the 0 h time point, illustrating the addition of the synthetic cannabinoid, WIN55, 212-2 (WIN), to the BEL7402 hepatocellular carcinoma cells (at concentrations of 5 and 10 µM; upper panels, the centre image and the right image, respectively) were inadvertently selected from the same original image. An error was made during the compilation of this Figure, and an incorrect image was selected for Fig. 4B, the upper right panel (showing the addition of 10 µM WIN). A corrected version of Fig 4 is presented, showing the correct data for Fig. 4B, which pertain to the 0 h time point on addition of 10 µM WIN to the cells. This error did not affect the overall conclusions reported in the present study. We sincerely apologize for this mistake, and thank the ...

We have demonstrated previously that mouse and human islets express ECS (endocannabinoid system) elements, and that short-term activation of islet cannabinoid CB1r and CB2r (cannabinoid type 1 and 2 receptors respectively) stimulates insulin secretion in vitro. There is evidence that the ECS is overactive in Type 2 diabetes, impairing glucose homoeostasis, but little is known about whether it is implicated in islet dysfunction. Therefore the aim of the present study was to investigate the effect of chronic exposure of isolated mouse islets to cannabinoid receptor agonists on islet gene expression and function. Quantitative RT-PCR (reverse transcription-PCR) indicated that mRNAs encoding synthesis [NAPE-PLD (N-acyl-phosphatidyl ethanolamide-hydrolysing phospholipase D)] and degradation [FAAH (fatty acid amide hydrolase)] of the endocannabinoid AEA (anandamide) were the most abundant ECS elements in mouse islets, with much lower levels of CB1r, CB2r, DAGL (diacylglycerol lipase) and MAGL ...
Using RNA (Northern) blot hybridization and reverse transcription-PCR, we demonstrate that the brain-type cannabinoid receptor (CB1-R) mRNA, but not the spleen-type cannabinoid receptor (CB2-R) mRNA, is expressed in the mouse uterus and that this organ has the capacity to synthesize the putative endogenous cannabinoid ligand, anandamide (arachidonylethanolamide). The psychoactive cannabinoid component of marijuana--delta 9-tetrahydrocannabinol (THC)--or anandamide, but not the inactive and nonpsychoactive cannabidiol (CBD), inhibited forskolin-stimulated cyclic AMP formation in the mouse uterus, which was prevented by pertussis toxin pretreatment. These results suggest that uterine CB1-R is coupled to inhibitory guanine nucleotide-binding protein and is biologically active. Autoradiographic studies identified ligand binding sites ([3H]anandamide) in the uterine epithelium and stromal cells, suggesting that these cells are perhaps the targets for cannabinoid action. Scatchard analysis of the ...
The avian retina has been used as a model to study signaling by different neuro- and gliotransmitters. It is unclear how dopaminergic and cannabinoid systems are related in the retina. Here we studied the expression of type 1 and 2 cannabinoid receptors (CB1 and CB2), as well as monoacylglycerol lipase (MAGL), the enzyme that degrades 2-arachidonoylglycerol (2-AG), during retina development. Our data show that CB1 receptor is highly expressed from embryonic day 5 (E5) until post hatched day 7 (PE7), decreasing its levels throughout development. CB1 is densely found in the ganglion cell layer (GCL) and inner plexiform layer (IPL). CB2 receptor was also found from E5 until PE7 with a decrease in its contents from E9 afterwards. CB2 was mainly present in the lamination of the IPL at PE7. MAGL is expressed in all retinal layers, mainly in the IPL and OPL from E9 to PE7 retina. CB1 and CB2 were found both in neurons and glia cells, but MAGL was only expressed in Müller glia. Older retinas (PE7) show CB1
Previous experiments have shown that LTP of field potential recordings in the hippocampus is blocked by cannabinoid receptor activation (Nowicky et al., 1987; Collins et al., 1994, 1995; Terranova et al., 1995). This inhibition could be caused by a direct effect on the protein(s) involved in long-term synaptic plasticity. Activation of cannabinoid receptors has been found to inhibit the production of cAMP via activation of a G-protein to which the receptor is coupled (Bidaut-Russell et al., 1990; Deadwyler et al., 1995). This decrease in cAMP could, in turn, reduce the activity of cAMP-dependent protein kinase, which has been identified as an important modulator of LTP (Brandon et al., 1997). Other direct effects on proteins involved in LTP and LTD are possible. However, cannabinoid receptor-mediated G-protein activation is also known to inhibit release of neurotransmitter in cultured hippocampal neurons (Shen et al., 1996). To determine whether cannabinoid receptor activation inhibits long-term ...
In a well-publicized article in the February 23, 2005 issue of the Journal of Neuroscience, researchers from Spain describe changes in cannabinoid receptors in the brains of AD patients, as well as animal behavioral and in-vitro data suggesting that cannabinoid agonists can protect neurons by reducing microglial activation.. The headlines on this study were predictably tantalizing (see, for example, Marijuana May Block Alzheimers), but also misleading. The mass media stories barely dug beyond the papers stated implication that marijuanas active ingredients could stem the progression of neurodegeneration. In reality, however, the story is more complicated and still unfolding. To begin with, two cannabinoid receptors have been identified. CB1 is the major type in brain, expressed by all types of nervous system cells, and apparently responsible for the psychoactive effects of the drug. CB2 is mainly expressed in immune system cells, but also in microglia (Benito et al., 2003), and may mediate ...
TY - JOUR. T1 - Regulation of hippocampal cannabinoid CB1 receptor actions by adenosine A1 receptors and chronic caffeine administration.

AU - Sebastião, Ana M. PY - 2011. Y1 - 2011. N2 - The cannabinoid CB(1) receptor-mediated modulation of γ-aminobutyric acid (GABA) release from inhibitory interneurons is important for the integrity of hippocampal-dependent spatial memory. Although adenosine A(1) receptors have a central role in fine-tuning excitatory transmission in the hippocampus, A(1) receptors localized in GABAergic cells do not directly influence GABA release. CB(1) and A(1) receptors are the main targets for the effects of two of the most heavily consumed psychoactive substances worldwide: Δ(9)-tetrahydrocannabinol (THC, a CB(1) receptor agonist) and caffeine (an adenosine receptor ...

We have investigated the adaptive changes of the human central cannabinoid receptor (CB1) stably expressed in Chinese hamster ovary cells (CHO-CB1), after agonist (CP 55,940) or selective CB1 inverse agonist (SR 141716) treatment. CB1 receptor density and affinity constant as measured by binding assays with both tritiated ligands remained essentially unchanged after varying period exposure of CHO-CB1 cells (from 30 min to 72 hr) to saturating concentrations of CP 55,940 or SR 141716. However, using a C-myc-tagged version of the CB1 receptor, FACS analysis and confocal microscopy studies on CB1 expression indicated that the agonist promoted a disappearance of cell surface receptor although inverse agonist increased its cell surface density. Taken together these results suggest that 1) agonist induces internalization of the receptor into a cellular compartment that would be still accessible to both the hydrophobic ligands CP 55,940 or SR 141716; 2) inverse-agonist promotes externalization of the ...
The actions of THC result from its partial agonist activity at the cannabinoid receptor CB1 (Ki = 10 nM[20]), located mainly in the central nervous system, and the CB2 receptor (Ki = 24 nM[20]), mainly expressed in cells of the immune system.[21] The psychoactive effects of THC are primarily mediated by the activation of cannabinoid receptors, which result in a decrease in the concentration of the second messenger molecule cAMP through inhibition of adenylate cyclase.[22]. The presence of these specialized cannabinoid receptors in the brain led researchers to the discovery of endocannabinoids, such as anandamide and 2-arachidonoyl glyceride (2-AG). THC targets receptors in a manner far less selective than endocannabinoid molecules released during retrograde signaling, as the drug has a relatively low cannabinoid receptor efficacy and affinity. In populations of low cannabinoid receptor density, THC may act to antagonize endogenous agonists that possess greater receptor efficacy.[23] THC is a ...
Cannabis-based medicines have a number of therapeutic indications, including anti-inflammatory and analgesic effects. The endocannabinoid receptor system, including the cannabinoid receptor 1 (CB1) and receptor 2 (CB2) and the endocannabinoids, are implicated in a wide range of physiological and pathophysiological processes. Pre-clinical and clinical studies have demonstrated that cannabis-based drugs have therapeutic potential in inflammatory diseases, including rheumatoid arthritis (RA) and multiple sclerosis. The aim of this study was to determine whether the key elements of the endocannabinoid signalling system, which produces immunosuppression and analgesia, are expressed in the synovia of patients with osteoarthritis (OA) or RA. Thirty-two OA and 13 RA patients undergoing total knee arthroplasty were included in this study. Clinical staging was conducted from x-rays scored according to Kellgren-Lawrence and Larsen scales, and synovitis of synovial biopsies was graded. Endocannabinoid levels were

In an increasingly ageing population, the incidence of neurodegenerative disorders such as Alzheimers disease, Parkinsons disease and Huntingtons 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 treatment of the symptoms and attempt to delay the progression of these diseases but there is currently no cure. Modulation of the endogenous cannabinoid system is emerging as a potentially viable option in the treatment of neurodegeneration. Endocannabinoid signalling has been found to be altered in many neurodegenerative disorders. To this end, pharmacological manipulation of the endogenous cannabinoid system, as well as application of phytocannabinoids and synthetic cannabinoids have been investigated. Signalling from the CB1 and CB2 receptors are ...
Basal Ganglia. CB1 receptors are expressed throughout the basal ganglia and have well established effects on movement in rodents. As in the hippocampus, these receptors inhibit the release of glutamate or GABA transmitter, resulting in decreased excitation or reduced inhibition based on the cell they are expressed in. Consistent with the variable expression of both excitatory glutamate and inhibitory GABA interneurons in both the basal ganglias direct and indirect motor loops, synthetic cannabinoids are known to influence this system in a dose-dependent triphasic pattern. Decreased locomotor activity is seen at both higher and lower concentrations of applied cannabinoids, while an enhancement of movement may occur upon moderate dosages. However, these dose-dependent effects have been studied predominately in rodents and the physiological basis for this triphasic pattern warrants future research in humans. Effects may vary based on the site of cannabinoid application, input from higher cortical ...

The cannabinoid signaling plays a significant role in controlling the local immune response on the skin. It has been found from research that endocannabinoids and phytocannabinoids modulated immune fluctuations. The homeostatic signaling of the ECS through its receptors CB1 and CB2 helps keep the production and release of pro-inflammatory cytokines and chemokines under control.. Cannabidiol (CBD) positively influences the endocannabinoid system (ECS) through its receptors CB1 and CB2. Due to this, it produces an anti-inflammatory effect when applied topically for cutaneous inflammation. Apart from this, other cannabinoids found in the hemp plant like cannabigerol (CBG), cannabichromene (CBC), CBGV, CBDV, And THCV are also known to produce anti-inflammatory effects when applied to the skin.. Apart from the above-mentioned skincare effects, the high lipid content of cannabidiol products like CBD oil helps to soothe the skin when applied topically. Also, the antioxidants contained in it helps with ...

M. Suaveolens Ledeb has long been used in China to treat inflammatory infectious diseases. Melilotus is extracted from Melilotus Suaveolens Ledeb and its therapeutic potential is associated with its anti-inflammatory activity. However, the precise mechanisms underlying its effects are unknown. This study was conducted to evaluate the protective effects of melilotus extract in a rat cecal ligation and puncture (CLP)-induced animal model of acute lung injury (ALI). A sepsis model was induced by CLP-like lung inflammation. Two hours prior to CLP administration, the treatment group was administered melilotus extract via oral injection. RT-PCR and Western blotting were used to test the expression of cannabinoid receptor (CB)2, NF-κβ and IκB from single peripheral blood mononuclear cells and lung tissues respectively. Enzyme linked immune sorbent assay was used to detect serum levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-10, and IL-12. The numbers of neutrophils, lymphocytes,

It has been hypothesized that heteromers of adenosine A2A receptors (A2AR) and cannabinoid CB1 receptors (CB1R) localized in glutamatergic nerve terminals mediate the integration of adenosine and endocannabinoid signaling involved in the modulation of striatal excitatory neurotransmission. Previous studies have demonstrated the existence of A2AR-CB1R heteromers in artificial cell systems. A dependence of A2AR signaling for the Gi protein-mediated CB1R signaling was described as one of its main biochemical characteristics. However, recent studies have questioned the localization of functionally significant A2AR-CB1R heteromers in striatal glutamatergic terminals. Using a peptide-interfering approach combined with biophysical and biochemical techniques in mammalian transfected cells and computational modeling, we could establish a tetrameric quaternary structure of the A2AR-CB1R heterotetramer. This quaternary structure was different to the also tetrameric structure of heteromers of A2AR with adenosine A1

The recently cloned CB2 cannabinoid receptor subtype was stably transfected into AtT-20 and Chinese hamster ovary cells to compare the binding and signal transduction properties of this receptor with those of the CB1 receptor subtype. The binding of [3H]CP 55,940 to both CB1 and CB2 was of similar high affinity (2.6 and 3.7 nM, respectively) and saturable. In competitive binding experiments, (-)-delta 9-tetrahydrocannabinol and CP 55,940 were equipotent at the CB1 and CB2 receptors, but WIN 55212-2 and cannabinol bound with higher affinity to the CB2 than the CB1 receptor. HU 210 had a higher affinity for the CB1 receptor. Anandamide, a recently identified endogenous cannabinoid agonist, was essentially equipotent at both receptor subtypes. The structurally related fatty acid ethanolamides dihomo-gamma-linolenylethanolamide and mead ethanolamide also bound with relatively equal affinity to both receptors, but adrenylethanolamide had a higher affinity for the CB1 receptor.

Cannabinoids and Opioids. There appears to be a synergistic analgesic (pain-relieving) benefit when cannabinoids are added to opioid treatment for pain in which there is a greater-than-additive benefical effect with the addition of cannabinoids. Studies indicate a trend towards reduced use of opioids when patients taking opioids add cannabinoids to their regimen. It is not uncommon for patients started on cannabinoids to be able to taper down or off opioids.. Interestingly, animal studies suggest that cannabinoids may reduce the development of tolerance to the analgesic benefits of opioids, resulting in less need for opioid dose escalation.. There is no enhancement of cardiorespiratory suppression from opioids with the addition of cannabinoids due to the very low density of cannabinoid (CB) receptors in brainstem cardiorespiratory centers. There does not appear to be any significant interactions with opioids regarding a cannabinoid effect on the metabolism of most opioids. However, there is ...

In addition to, CB1-D2 receptor heteromers, not long ago Together with the aid of biochemical and biophysical research CB1-CB2 receptor heteromers is documented in nucleus accumbens and globus pallidus [175]. Typical attribute aspect observed with CB1-CB2 receptor heteromers is, CB1 receptor antagonists blocks the result of CB2 receptor agonists and, conversely, CB2 receptor antagonists blocks the result of CB1 receptor agonists As a result demonstrating a bidirectional phenomenon of cross-antagonism [175]. These heteromers may well describe preceding conflicting effects and could serve as therapeutic targets. Modern evidence implies that dopamine modulates the activity of SNpc neurons not just by regular dopamine receptors, but additionally by CB1 receptors, probably by using N-arachidonoyl-dopamine [176]. Besides localization of CB1, the presence and functional purpose of TRPV1 on dopaminergic nigral neurons and their position in modulating synaptic transmission throughout the SNpc have also ...

Infections during pregnancy and adolescent cannabis use have both been identified as environmental risk factors for schizophrenia. We combined these factors in an animal model and looked at their effects, alone and in combination, on serotonin 5HT1A receptor binding (5HT1AR) binding longitudinally from late adolescence to adulthood. Pregnant rats were exposed to the viral mimic poly I:C on embryonic day 15. Adolescent offspring received daily injections of the cannabinoid HU210 for 14 days starting on postnatal day (PND) 35. Hippocampal and cortical 5HT1AR binding was quantified autoradiographically using [3H]8-OH-DPAT, in late adolescent (PND 55), young adult (PND 65) and adult (PND 90) rats. Descendants of poly I:C treated rats showed significant increases of 15?18% in 5HT1AR in the hippocampus (CA1) compared to controls at all developmental ages. Offspring of poly I:C treated rats exposed to HU210 during adolescence exhibited even greater elevations in 5HT1AR (with increases of 44, 29, and ...
