decarboxylase/cannabis

Investigation of the cannabinoid system in a vertebrate group phylogenetically distant from mammals might improve understanding of its physiological role. Thus, in the present study, the distribution of the cannabinoid CB1 receptor has been investigated in the brain of Xenopus laevis (anuran

BACKGROUND Levels of cannabinoid 1 receptor (CB1R) messenger RNA (mRNA) and protein, which are expressed most heavily in the cholecystokinin class of γ-aminobutyric acid (GABA) neurons, are lower in the dorsolateral prefrontal cortex in schizophrenia, and the magnitude of these differences is

Schizophrenia is a devastating neurodevelopmental disorder that affects approximately 1% of the population. Reduced expression of the 67-kDa protein isoform of glutamic acid decarboxylase (GAD67) is a hallmark of the disease and is encoded by the GAD1 gene. In schizophrenia, GAD67 downregulation

Cannabinoids have been reported to be involved in affecting various biological functions through binding with cannabinoid receptors type 1 (CB1) and 2 (CB2). The present study was designed to investigate whether swallowing, an essential component of feeding behavior, is modulated after the

Double-label in situ hybridization was used to identify the phenotypes of striatal neurons that express mRNA for cannabinoid CB(1) receptors. Simultaneous detection of multiple mRNAs was performed by combining a (35)S-labeled ribonucleotide probe for CB(1) mRNA with digoxigenin-labeled riboprobes

The endocannabinoid system has been implicated in several neurobiological processes, including neurodegeneration, neuroprotection and neuronal plasticity. The CB1 cannabinoid receptors are abundantly expressed in the basal ganglia, the circuitry that is mostly affected in Parkinson's Disease (PD).

A long line of experimental evidence indicates that endogenous cannabinoid mechanisms play important roles in nociceptive information processing in various areas of the nervous system including the spinal cord. Although it is extensively documented that the cannabinoid-1 receptor (CB(1)-R) is

Neuronal electrical oscillations in the theta (4-14 Hz) and gamma (30-80 Hz) ranges are necessary for the performance of certain animal behaviours and cognitive processes. Perisomatic GABAergic inhibition is prominently involved in cortical oscillations driven by ACh release from septal cholinergic

At present, little is known about the mechanisms by which cannabinoids exert their effects on the central nervous system. In this study, fluorescence imaging and electrophysiological techniques were used to investigate the functional relationship between cell surface cannabinoid type 1 (CB(1))

OBJECTIVE Stiff-person syndrome (SPS) is an uncommon and disabling disorder characterized by progressive rigidity and episodic painful spasms involving axial and limb musculature. SPS treatment is mostly based on benzodiazepines, baclofen, immunosuppressants and intravenous immunoglobulin. Cannabis

The acute effects of cannabinoid drugs on the synthesis of noradrenaline, dopamine, and serotonin (5-HT) were assessed, simultaneously, using the accumulation of 3,4-dihydroxyphenylalanine (dopa) and 5-hydroxytryptophan (5-HTP) after decarboxylase inhibition as a measure of the rate of tyrosine and

We have recently examined the status of the endocannabinoid transmission in the basal ganglia in Huntington's disease (HD) using a rat model generated by bilateral intrastriatal injections of 3-nitropropionic acid (3-NP). In these previous studies, we focused on the early phase of hyperactivity that

Repeated, but not single, intraperitoneal injections of delta1,6-tetrahydrocannabinol (delta1,6-THC) 20 mg/kg to rats administered daily for two weeks, produced increased gamma-aminobutyric acid (GABA) concentration and decreased glutamic acid decarboxylase (GAD) activity in the cerebellum, as well

Type 1 cannabinoid receptor (CB1) is the principal mediator of retrograde endocannabinoid signaling in the brain. In this study, we addressed the topographic distribution and amino acid neurotransmitter phenotype of endocannabinoid-sensitive hypothalamic neurons in mice. The in situ hybridization

Cannabinoid receptors (CNRs) in basal ganglia are located on striatal efferent neurons which are gamma-aminobutiric acid (GABA)-containing neurons. Recently, we have demonstrated that CN-induced motor inhibition is reversed by GABA-B, but not GABA-A, receptor antagonists, presumably indicating that
