Endocannabinoid 2-arachidonyl glycerol is a full agonist through human type 2 cannabinoid receptor: antagonism by anandamide.
The endocannabinoids anandamide and 2-arachidonyl glycerol (2-AG) bind to G protein-coupled central and peripheral cannabinoid receptors CB1 and CB2, respectively. Due to the relatively high expression of the CB2 isotype on peripheral immune cells, it has been hypothesized that this receptor mediates the immunosuppressive effects of cannabinoids. Unfortunately, there was a dearth of pharmacolog...
متن کاملComparison of effects of anandamide at recombinant and endogenous rat vanilloid receptors.
BACKGROUND Anandamide, an endogenous lipid, activates both cannabinoid (CB(1)) and vanilloid (VR1) receptors, both of which are co-expressed in rat dorsal root ganglion (DRG) cells. Activation of either receptor results in analgesia but the relative contribution of CB(1) and VR1 in anandamide-induced analgesia remains controversial. Here we compare the in vitro pharmacology of recombinant and e...
متن کاملThe endogenous cannabinoid anandamide activates vanilloid receptors in the rat hippocampal slice.
We have previously reported that the synthetic cannabinoid receptor agonist WIN55,212-2 causes a selective reduction in paired-pulse depression of population spikes in the CA1 region of the rat hippocampal slice. This effect is consistent with the observation that activation of cannabinoid receptors inhibits GABA release in the hippocampus. We have now investigated the actions of the putative e...
متن کاملCapsazepine, a Transient Receptor Potential Vanilloid Type 1 (TRPV1) Antagonist, Attenuates Antinociceptive Effect of CB1 Receptor agonist, WIN55,212-2, in the Rat Nucleus Cuneiformis
Introduction: Nucleus cuneiformis (NCF), as part of descending pain inhibitory system, cooperates with periaqueductal gray (PAG) and rostral ventromedial medulla (RVM) in supraspinal modulation of pain. Cannabinoids have analgesic effects in the PAG, RVM and NCF. The transient receptor potential vanilloid type 1(TRPV1) can be activated by anandamide and WIN55,212-2 as a cannabinoid receptor ago...
متن کاملAgonist-dependent potentiation of vanilloid receptor transient receptor potential vanilloid type 1 function by stilbene derivatives.
Transient receptor potential vanilloid type 1 (TRPV1) is a nonselective cation channel activated by capsaicin, low pH, and noxious heat and plays a key role in nociception. Understanding mechanisms for functional modulation of TRPV1 has important implications. One characteristic of TRPV1 is that channel activity induced by either capsaicin or other activators can be sensitized or modulated by f...
