Cannabinoid receptors (nomenclature as agreed by the NC-IUPHAR Subcommittee on Receptors [119]) are activated endogenous ligands that include N-arachidonoylethanolamine (anandamide), N-homo-γ-linolenoylethanolamine, N-docosatetra-7,10,13,16-enoylethanolamine and 2-arachidonoylglycerol. Potency determinations of agonists at these complicated possibility differential susceptibility to enzymatic c...

Introduction: The Cannabinoid receptors (CBR) densities are high within the cerebellum. Cannabinoid receptors manipulations have been reported to cause altering the cerebellar functions. harmaline have immune-modulatory effects in several studies. i.e., significant anti-inflammatory effect via the inhibition of prostaglandin E2 (PGE2) and tumor necrosis factor alpha (TNF-α). Endocannabino...

Introduction: Previous studies have shown that the basolateral amygdale (BLA) is rich of CB1 cannabinoid receptors and involved in cannabinoid-induced antinociception. Also, it seems that there are functional interactions between the cannabinoid CB1 and opioid receptors in the process of sensitization to opiates. In the present study, we tried to examine the role of intra-BLA cannabinoid rece...

This chapter will review the basic pharmacology of endocannabinoid receptors. As the best-described cannabinoid receptors are G-protein-coupled receptors (GPCRs), those will be the focus of this chapter. We will start with a basic review of GPCR signaling, as these concepts are critical to understanding the function of cannabinoid receptors. Next, several features of cannabinoid receptor signal...

background and objectives cannabinoids which are active compounds of marijuana show some pharmacological effects similar to the opioids. there are also functional interactions between both cannabinoid and opioid systems. in this study we investigated the role of cannabinoid receptors in central amygdala and its interaction with opioid system.   methods in the present study, we investigated the ...

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 used as an in vitro model to investigate cannabinoid-induced neurite remodeling effects and to iden...

GPR18, GPR55 and GPR119 (provisional nomenclature), although showing little structural similarity to CB1 CB2 cannabinoid receptors, respond endogenous agents analogous the ligands, as well some natural/synthetic receptor ligands [104]. Although there are multiple reports indicate that can be activated in vitro by N-arachidonoylglycine, lysophosphatidylinositol N-oleoylethanolamide, respectively...

Objective(s) The objective of this study was to evaluate the effect of cannabinoid on cortical spreading depression (CSD) in rat brain. Cannabis has been used for centuries for both symptomatic and prophylactic treatment of different types of headaches including migraine. CSD is believed to be a putative neuronal mechanism underlying migraine aura and subsequent pain. Materials and Methods T...
