Neuronal muscarinic acetylcholine receptor subtype modulation of inspiratory bursting at hypoglossal motoneurons in developing neonatal mice in vitro

Physiology, 2023
Muscarinic acetylcholine receptor modulation contributes to changes in hypoglossal motoneuron excitability through pre- and post-synaptic effects, an important mechanism for regulation of airway tone during sleep.

Selectivity mechanism of muscarinic acetylcholine receptor antagonism through in silico investigation.

Physical Chemistry, Chemical Physics - PCCP, 2022
Structures of muscarinic acetylcholine receptors illustrate the strikingly high degree of homology of the residues among isoforms, thus leading to difficulty in achieving subtype selectivity when targeting these receptors and causing undesired side ...

Functional expression of rat M5 muscarinic acetylcholine receptor in yeast

Biochemical and Biophysical Research Communications, 1992
We have produced the rat M5 muscarinic acetylcholine receptor, an integral membrane protein, in the yeast Saccharomyces cerevisiae. This was achieved by placing an M5 gene in the yeast vector under the control of the yeast alpha-factor promoter and leader sequence.

Effects of postnatal maturation on muscarinic acetylcholine receptor distribution in hypoglossal motorneurons

The FASEB Journal, 2022
Upper airway patency is decreased during rapid eye movement (REM) sleep due to loss of genioglossus (primary tongue protruder) tongue muscle tone.

Role for M5 muscarinic acetylcholine receptors in cocaine addiction

Journal of Neuroscience Research, 2003
AbstractMuscarinic cholinergic receptors of the M5 subtype are expressed by dopamine‐containing neurons of the ventral tegmentum. These M5 receptors modulate the activity of midbrain dopaminergic neurons, which play an important role in mediating reinforcing properties of abused psychostimulants like cocaine.

Intramolecular interactions in muscarinic acetylcholine receptors studied with chimeric m2/m5 receptors.

Molecular Pharmacology, 1994
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 ...

Structural Features of Iperoxo-BQCA Muscarinic Acetylcholine Receptor Hybrid Ligands Determining Subtype Selectivity and Efficacy.

ACS Chemical Neuroscience, 2021
Selective agonists for the human M1 and M4 muscarinic acetylcholine receptors (mAChRs) are attractive candidates for the treatment of cognitive disorders, such as Alzheimer's disease and schizophrenia.

Human skin fibroblasts express m2, m4, and m5 subtypes of muscarinic acetylcholine receptors

Journal of Cellular Biochemistry, 1999
Previous studies have demonstrated that muscarinic acetylcholine receptors (mAChRs) are expressed by human skin fibroblasts (HSF). We have identified the molecular subtypes of these receptors by reverse transcription-polymerase chain reaction (RT-PCR), using m1-m5 subtype-specific primers.

Novel insights into M5 muscarinic acetylcholine receptor function by the use of gene targeting technology

Life Sciences, 2003
Until recently, little was known about the possible physiological functions of the M(5) muscarinic acetylcholine receptor subtype, the last member of the muscarinic receptor family (M(1)-M(5)) to be cloned. To learn more about the potential physiological roles of this receptor subtype, we generated and analyzed M(5) receptor-deficient mice (M5 -/- mice)
