Endocannabinoid system plays an important role in the regulation of diverse physiological functions. Although cannabinoid type 2 receptors (CB2) are involved in the modulation of immune system in peripheral tissues, recent findings demonstrated that they are also expressed in the central nervous

The present study demonstrates a novel stimulatory effect of a cannabinoid agonist on calcium channels. DALN (1 nM) potentiated 45Ca(2+)-uptake by N18TG2 neuroblastoma cells, an effect that was abolished by the specific CB1 receptor antagonist SR141716A. The stimulation of 45Ca(2+)-uptake by DALN

Introduction: Δ9-Tetrahydrocannabinol (THC), the principle psychoactive ingredient in Cannabis, is widely used for its therapeutic effects in a large variety of diseases, but it also has numerous neurological side effects. The cannabinoid receptors (CBRs) are responsible to a large extent for these,

The morphological remodeling of neuronal cells influences neurogenesis and brain functions. We hypothesize that psychoactive and neurotoxic effects of cannabinoids may be mediated, at least in part, by their morphoregulatory activities. In the present study, mouse neuroblastoma N1E-115 cells were

The cannabinoid receptor that has been pharmacologically characterized for hypothermia, spontaneous activity, analgesia and catalepsy in rodents is the same pharmacological receptor that inhibits adenylate cyclase in vitro. The inhibition of adenylate cyclase by the cannabinoid receptor results from

Although coupled to G(i/o) proteins, cannabinoid CB(1) receptors can also activate intracellular Ca(2+) ([Ca(2+)](i)) accumulation through not fully understood mechanisms. We report that in, human neuroblastoma SH-SY5Y cells, CB(1) activation with the specific agonist arachidonoylchloroethanolamide

The predominant animal model in which the pharmacology of cannabinoids is studied is the mouse. Nonetheless, the structure and functional expression of the mouse cannabinoid receptor (CB1) gene have not been reported. We have cloned and expressed the gene for the mouse CB1 receptor and compared its

G protein-coupled receptors (GPCRs) are important regulators of cellular signaling functions and therefore are a major target for drug discovery. The CB1 cannabinoid receptor is among the most highly expressed GPCRs in neurons, where it regulates many differentiated neuronal functions. One model

In addition to their inhibitory effects, cannabinoids also exert stimulatory activity which can be detected at the cellular level. In a previous study, we demonstrated a stimulatory effect of the synthetic cannabinoid receptor agonist desacetyllevonantradol (DALN) on Ca(2+) flux into N18TG2

Functional interactions between catecholamines and cannabinoid transmission systems could explain the influence of Delta(9)-tetrahydrocannabinol on several central activities. Hence, the presence of cannabinoid CB(1) receptors in tyrosine hydroxylase (TH) containing cells has been suggested,

OBJECTIVE
The aim of this study was to investigate the effect of the epigenetic modifiers trichostatin A and 5-aza-2'-deoxycytidine on the expression of the cannabinoid receptors CB1 and CB2 and μ-opioid receptors in human SH SY5Y neuroblastoma cells and human Jurkat T lymphocytes.

Cannabinoids activate several members of the mitogen-activated protein kinase superfamily including p44 and p42 extracellular signal-regulated kinase (ERK). We used N1E-115 neuroblastoma cells and the cannabinoid receptor agonist WIN 55,212-2 (WIN) to examine the signal transduction pathways leading

The CB1 cannabinoid receptor has been shown to couple with pertussis toxin (PTX)-sensitive Gi/o proteins and inhibit adenylyl cyclase. However, in certain conditions, CB1 mediates adenylyl cyclase activation, possibly through Gs-type G proteins. In rat B103 neuroblastoma cells in which CBI gene was
