The problem of new psychoactive substances is emerging globally. Cannabinoid receptors mediate the action of synthetic cannabinoids, which are one of most abused drugs. Recently, cannabinoid receptors 1 (CB1R) have been reported to silence glutamatergic nerve terminals in cerebellar granule cells via synaptic vesicle redistribution. This study aimed to determine whether synthetic cannabinoid ad...
BACKGROUND AND PURPOSE The non-psychotropic cannabinoid cannabichromene is known to activate the transient receptor potential ankyrin-type1 (TRPA1) and to inhibit endocannabinoid inactivation, both of which are involved in inflammatory processes. We examined here the effects of this phytocannabinoid on peritoneal macrophages and its efficacy in an experimental model of colitis. EXPERIMENTAL A...
OBJECTIVES This article attempts to cover pragmatic clinical considerations involved in the use of cannabinergic medicines in pain practice, including geographical and historical considerations, pharmacokinetics, pharmacodynamics, adverse effects, drug interactions, indications, and contraindications. Topics include molecular considerations such as the 10-fold greater abundance of cannabinoid t...
PURPOSE Preservation of the ocular surface barrier requires complex control of epithelial cell proliferation and inflammation mechanisms. The endocannabinoid system may be regulating these processes. Therefore, the authors explored the presence and properties of cannabinoid receptors (CB1 and CB2) in conjunctival epithelial cells. METHODS The authors used immunohistochemistry to detect CB1 an...
Cannabinoid receptors are widely distributed in the nuclei of the extrapyramidal motor and mesolimbic reward systems; their exact functions are, however, not known. The aim of the present study was to characterize the effects of cannabinoids on the electrically evoked release of endogenous dopamine in the corpus striatum and the nucleus accumbens. In rat brain slices dopamine release elicited b...
BACKGROUND Cannabinoid receptor agonists inhibit inflammatory hyperalgesia in animal models. Nonselective cannabinoid receptor agonists also produce central nervous system (CNS) side effects. Agonists selective for CB2 cannabinoid receptors, which are not found in the CNS, do not produce the CNS effects typical of nonselective cannabinoid receptor agonists but do inhibit acute nociception. The ...

Cannabinoid CB(1) receptors in the cerebellum mediate the inhibitory effects of Delta(9)-tetrahydrocannabinol (THC) on motor coordination. Intracellular effects of CB(1) receptors include inhibition of adenylyl cyclase via activation of G(i/o) proteins. There is evidence for the convergence of other neuronal receptors, such as adenosine A(1) and GABA(B), with the cannabinoid system on this sign...
Cannabinoids exert various biological effects that are either receptor-mediated or independent of receptor signaling. Mitochondrial effects of cannabinoids were interpreted either as non-receptor-mediated alteration of mitochondrial membranes, or as indirect consequences of activation of plasma membrane type 1 cannabinoid receptors (CB1). Recently, CB1 receptors were confirmed to be localized t...
Cannabis is one of the most prevalent drugs used in industrialized countries. The main effects of Cannabis are mediated by two major exogenous cannabinoids: ∆9-tetrahydroxycannabinol and cannabidiol. They act on specific endocannabinoid receptors, especially types 1 and 2. Mammals are endowed with a functional cannabinoid system including cannabinoid receptors, ligands, and enzymes. This endoca...
