TLR2 and TLR4 Modulate Mouse Ileal Motility by the Interaction with Muscarinic and Nicotinic Receptors

open access: yesCells, 2022
Irritable bowel syndrome (IBS) is a chronic functional bowel disorder characterized by intestinal dysmotility. Changes in intestinal microbiota (dysbiosis) can lead to alterations in neuro-muscular functions in the gut. Toll-like receptors (TLRs) 2 and 4

Selective M3 Muscarinic Receptor Antagonist Inhibits Small-Cell Lung Carcinoma Growth in a Mouse Orthotopic Xenograft Model

open access: yesJournal of Pharmacological Sciences, 2011
.: In small cell lung carcinoma (SCLC), acetylcholine (ACh) is synthesized and secreted, and it acts as an autocrine growth factor through activation of its receptors, muscarinic receptor (mAChR) and nicotinic receptor (nAChR). Alteration of tumor growth

Long-Term—But Not Short-Term—Plasticity at the Mossy Fiber–CA3 Pyramidal Cell Synapse in Hippocampus Is Altered in M1/M3 Muscarinic Acetylcholine Receptor Double Knockout Mice

open access: yesCells, 2023
Muscarinic acetylcholine receptors are well-known for their crucial involvement in hippocampus-dependent learning and memory, but the exact roles of the various receptor subtypes (M1–M5) are still not fully understood.

Beneficial metabolic effects of M3 muscarinic acetylcholine receptor deficiency [PDF]

open access: yesCell Metabolism, 2006
Most animal models of obesity and hyperinsulinemia are associated with increased vagal cholinergic activity. The M3 muscarinic acetylcholine receptor subtype is widely expressed in the brain and peripheral tissues and plays a key role in mediating the physiological effects of vagal activation.

The Cholinergic Pathways in Inflammation: A Potential Pharmacotherapeutic Target for COPD

open access: yesFrontiers in Pharmacology, 2018
In COPD, the activity of the cholinergic system is increased, which is one of the reasons for the airflow limitation caused by the contraction of airway smooth muscles.

Cholinergic receptor alterations in the cerebral cortex of spinal cord injured rat

open access: yesBiochemistry and Biophysics Reports, 2017
Many areas of the cerebral cortex process sensory information or coordinate motor output necessary for control of movement. Disturbances in cortical cholinergic system can affect locomotor coordination.

Molecular Modeling of the M3 Acetylcholine Muscarinic Receptor and Its Binding Site [PDF]

open access: yesJournal of Biomedicine and Biotechnology, 2012
The present study reports the results of a combined computational and site mutagenesis study designed to provide new insights into the orthosteric binding site of the human M3 muscarinic acetylcholine receptor. For this purpose a three-dimensional structure of the receptor at atomic resolution was built by homology modeling, using the crystallographic ...

Cholinergic Regulation of Orexin/Hypocretin Neurons Through M3Muscarinic Receptor in Mice

open access: yesJournal of Pharmacological Sciences, 2008
The cholinergic system plays an important role in regulation of arousal and REM sleep. In the present study, we showed that a muscarinic receptor agonist, carbachol (CCh), activates almost 20% of orexin-producing neurons (orexin neurons), which play a ...
