The dual-site agonist for human M2 muscarinic receptors Iper-8-naphtalimide induces mitochondrial dysfunction in Saccharomyces cerevisiae [PDF]
Microbial CellGlioblastoma 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 ...

Aberrant myocardial calcium cycling: pathogenic mechanisms and targeted therapeutics for heart failure [PDF]
Frontiers in Cardiovascular MedicineCardiovascular diseases rank as the global primary cause of mortality. Heart failure (HF) represents a progressive cardiac syndrome triggered by structural or functional myocardial damage that compromises ventricular systolic output.

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

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

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
