Cannabinoid CB1 and CB2 Receptor Signaling and Bias
An agonist that acts through a single receptor can activate numerous signaling pathways. Recent studies have suggested that different ligands can differentially activate these pathways by stabilizing a limited range of receptor conformations, which in turn preferentially drive different downstream signaling cascades. This concept, termed "biased signaling" represents an exciting therapeutic opp...
متن کاملChemical Cannabis; the New Trend of Addiction in Iran
Synthetic cannabinoids (SC) are a heterogeneous group of substances with a high affinity for cannabinoid receptors. Unlike Δ9-tetrahydrocannabinol (THC), synthetic cannabinoids are incredibly potent, highly productive, have more affinity for the Cannabinoid receptor type 1 (CB1), and Cannabinoid receptor type 2 (CB2), and are designed to accelerate the effects of tetrahydrocannabinol. Also, the...
متن کاملNeural Effects of Cannabinoid CB1 Neutral Antagonist Tetrahydrocannabivarin on Food Reward and Aversion in Healthy Volunteers
BACKGROUND Disturbances in the regulation of reward and aversion in the brain may underlie disorders such as obesity and eating disorders. We previously showed that the cannabis receptor subtype (CB1) inverse agonist rimonabant, an antiobesity drug withdrawn due to depressogenic side effects, diminished neural reward responses yet increased aversive responses (Horder et al., 2010). Unlike rimon...
متن کاملmidazolam-induced learning and memory impairment is modulated by cannabinoid cb1 receptor agonist and antagonist
background: memory impairment is a well-known effect of many benzodiazepine compounds which is mediated through their action on gamma-aminobutyric acid type a (gabaa) receptors. on the other hand, cannabinoids can affect learning and memory process through presynaptic modulation of the release of both excitatory glutamate and inhibitory gaba transmitters in brain regions involved in learning an...
متن کاملInteraction between Antagonist of Cannabinoid Receptor and Antagonist of Adrenergic Receptor on Anxiety in Male Rat
Introduction: Anxiety is among the most common and treatable mental disorders. Adrenergic and cannabinoid systems have an important role in the neurobiology of anxiety. The elevated plus-maze (EPM) has broadly been used to investigate anxiolytic and anxiogenic compounds. The present study investigated the effects of intraperitoneal (IP) injection of cannabinoid CB1 receptor antagonist (AM251) i...
