Abstract:Peripheral inflammation can be regulated by activation of brain muscarinic acetylcholine receptor (mAChR)-dependent signaling functionally associated with a vagus-nerve mediated anti-inflammatory circuit (Proc Natl Acad Sci USA, 2006, 5219; Brain Behav Immun, 2009, 23:41). Here, we studied the specific role of the M1 mAChR subtype in this regulation by utilizing BQCA, a highly specific allosteric M1 mAChR activator that crosses the blood-brain barrier. Single drug (5,10 or 20 mg/kg, i.p) administration in mice… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
