The dual-site agonist for human M2 muscarinic receptors Iper-8-naphtalimide induces mitochondrial dysfunction in <i>Saccharomyces cerevisiae</i>. [PDF]

Microb Cell
Glioblastoma is a malignant astrocytic tumor of the brain. A significantly decrease of glioblastoma cell proliferation and survival can be achieved by activating the M2 muscarinic acetylcholine receptor (a G protein-coupled receptor, or GPCR) with two ...

Muscarinic receptor regulation of chronic pain-induced atrial fibrillation

Frontiers in Cardiovascular Medicine, 2022
Atrial fibrillation (AF), one of the most common arrhythmias, is associated with chronic emotional disorder. Chronic pain represents a psychological instability condition related to cardiovascular diseases, but the mechanistic linkage connecting chronic ...

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

General anaesthesia-related complications of gut motility with a focus on cholinergic mechanisms, TRP channels and visceral pain

Frontiers in Physiology, 2023
General anesthesia produces multiple side effects. Notably, it temporarily impairs gastrointestinal motility following surgery and causes the so-called postoperative ileus (POI), a multifactorial and complex condition that develops secondary to ...

Vibrational spectroscopy analysis of ligand efficacy in human M2 muscarinic acetylcholine receptor (M2R)

Communications Biology, 2021
Katayama et al. report a vibrational spectroscopic study using ATR–FTIR of the human M2 muscarinic acetylcholine receptor (M2R). Their work involves an extensive comparison of agonists, antagonists, and inverse agonists, in which they show that they C ...

Synergistic mechanisms of medullary cholinergic-serotonergic pathway interactions in regulating neuronal excitability and locomotor activities. [PDF]

Commun Biol
Medullary serotonergic (5-HT) neurons play a pivotal role in locomotor initiation. While these neurons receive cholinergic innervation, the functional consequences and underlying mechanisms remain poorly understood. Using ePet-EYFP transgenic mice (P3–P6)

Dysfunctional Presynaptic M2 Receptors in the Presence of Chronically High Acetylcholine Levels: Data from the PRiMA Knockout Mouse. [PDF]

PLoS ONE, 2015
The muscarinic M2 receptor (M2R) acts as a negative feedback regulator in central cholinergic systems. Activation of the M2 receptor limits acetylcholine (ACh) release, especially when ACh levels are increased because acetylcholinesterase (AChE) activity

Histamine H1 Receptor Down-Regulation Mediated by M3 Muscarinic Acetylcholine Receptor Subtype

Journal of Pharmacological Sciences, 2004
Heterologous down-regulation of histamine H1 receptor (H1R) mediated by muscarinic acetylcholine receptor subtype was investigated using five kinds of Chinese hamster ovary (CHO) cells stably co-expressing the human H1R and one of the five (M1 –M5 ...

Position of anticholinergic drugs in the treatment of childhood asthma [PDF]

Srpski Arhiv za Celokupno Lekarstvo, 2010
Anticholinergic drugs block muscarinic effect of acetylcholine on the receptors of postjunctional membranes and so inhibit the answer of the postganglionic parasympathetic nerve.
