Desensitization of human muscarinic acetylcholine receptor m2 subtypes (hm2 receptors) stably expressed in chinese hamster ovary cells was measured as decreases in the carbamylcholine-stimulated [35S]GTPgammaS binding activity in membrane preparations after pre-treatment of cells with carbamylcholine.

Neuraminidase and slight acid hydrolysis were used to investigate the role of sialic acid residues in the binding of muscarinic agonists and antagonists to membranes from tissues rich in M1 and M2 receptors. Membranes were pretreated with neuraminidase at pH 5 and the binding parameters were determined from competitive experiments with (3H ...

Muscarinic acetylcholine receptors bind allosteric modulators at a site apart from the orthosteric site used by conventional ligands. We tested in cardiac tissue whether modulator binding to ligand-occupied muscarinic M2 receptors is a preferential event that can be detected using a radioactive allosteric agent. The newly synthesized dimethyl-W84 (N,N'-

Effects of Autoantibodies against M2 Muscarinic Acetylcholine Receptors on Rabbit Atria in vivo
Cardiology, 2008<i>Background:</i> Evidence has shown that autoantibodies against M2 muscarinic acetylcholine receptors may play a role in the development of atrial fibrillation. The goal of this study was to evaluate the effects of anti-M2 receptor autoantibodies on rabbit atria in vivo.

Current models of the three-dimensional structures of muscarinic acetylcholine receptors and other G protein-coupled receptors are based primarily on high-resolution electron diffraction data obtained with bacteriorhodopsin, the molecular structure of which is characterized by the presence of seven alpha-helical transmembrane domains (TM I-VII ...

We have compared muscarinic acetylcholine receptor (mAChR) coupling to phospholipase C (PLC) and increases in cytoplasmic Ca2+ concentration [Ca2+]i in human embryonic kidney (HEK) cells, stably expressing either the human m3 or m2 receptor subtype. In m3 mAChR-expressing cells, carbachol stimulated inositol phosphate (InsP) formation and increased ...

The carotid body is a major arterial chemoreceptor that senses low O2 tension, high CO2 tension and low pH in the arterial blood. It is generally believed that neurotransmitters, including acetylcholine (ACh), participate in the genesis of afferent neural output from the carotid body and modulate the function of chemoreceptor cells (glomus cells ...

Design and Synthesis of Novel Ligands for the M2 Muscarinic Acetylcholine Receptor
2020The M2 muscarinic acetylcholine receptor (M2R) belongs to a highly conserved five-membered family within the class A of G protein-coupled receptors (GPCRs).5-7 The five subtypes are ubiquitously expressed and play a key role in numerous physiological processes.15, 17, 18 Upon activation, the M2R causes, among other things, negative chronotropy and ...
