Structural determinants at the M2 muscarinic receptor modulate the RGS4-GIRK response to pilocarpine by impairment of the receptor voltage sensitivity [PDF]
Scientific Reports, 2017 Membrane potential controls the response of the M2 muscarinic receptor to its ligands. Membrane hyperpolarization increases response to the full agonist acetylcholine (ACh) while decreasing response to the partial agonist pilocarpine.

Non-Neuronal Functions of the M2 Muscarinic Acetylcholine Receptor [PDF]
Genes, 2013 Acetylcholine is an important neurotransmitter whose effects are mediated by two classes of receptors. The nicotinic acetylcholine receptors are ion channels, whereas the muscarinic receptors belong to the large family of G protein coupled seven ...

First-in-Human Assessment of 11C-LSN3172176, an M1 Muscarinic Acetylcholine Receptor PET Radiotracer
Journal of Nuclear Medicine, 2020 Visual Abstract This was a first-in-human study of the PET radiotracer 11C-LSN3172176 for the muscarinic acetylcholine receptor subtype M1. The objectives of the study were to determine the appropriate kinetic model to quantify binding of the tracer to ...

Evolution of the Muscarinic Acetylcholine Receptors in Vertebrates [PDF]
eneuro, 2018 The family of muscarinic acetylcholine receptors (mAChRs) consists of five members in mammals, encoded by the CHRM1-5 genes. The mAChRs are G-protein-coupled receptors, which can be divided into the following two subfamilies: M2 and M4 receptors coupling to Gi/o; and M1, M3, and M5 receptors coupling to Gq/11.

Allosteric Modulation of Muscarinic Acetylcholine Receptors [PDF]
Current Neuropharmacology, 2007 Muscarinic acetylcholine receptors (mAChRs) are prototypical Family A G protein coupled-receptors. The five mAChR subtypes are widespread throughout the periphery and the central nervous system and, accordingly, are widely involved in a variety of both physiological and pathophysiological processes.

Distinct agonist regulation of muscarinic acetylcholine M2-M3 heteromers and their corresponding homomers [PDF]
, 2015 Each subtype of the muscarinic receptor family of G protein-coupled receptors is activated by similar concentrations of the neurotransmitter acetylcholine or closely related synthetic analogs such as carbachol. However, pharmacological selectivity can be

Involvement of muscarinic receptors in psychomotor hyperactivity in dopamine-deficient mice
Molecular Brain, 2022 Dopamine-deficient (DD) mice exhibit psychomotor hyperactivity that might be related to a decrease in muscarinic signaling. In the present study, muscarinic acetylcholine receptor M2 (CHRM2) density decreased in the cortex in DD mice. This is significant
