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

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

Effects of novel muscarinic M3 receptor ligand C1213 in pulmonary arterial hypertension models. [PDF]
Pulmonary hypertension (PH) is a complex disease comprising a pathologic remodeling and thickening of the pulmonary vessels causing an after load on the right heart ventricle that can result in ventricular failure. Triggered by oxidative stress, episodes

Anti-M3 muscarinic acetylcholine receptor antibodies in patients with Sjögren’s syndrome
Sjögren's syndrome (SS) is an autoimmune disease that affects exocrine glands including salivary and lacrimal glands. Recently, autoantibodies against muscarinic acetylcholine receptor M3 (M3R) have been detected in serum from 9 to 100 % of patients with SS in addition to anti-SS-A and anti-SS-B antibodies.

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

Characterization of the positive and negative inotropic effects of acetylcholine in the human myocardium [PDF]
In the human isolated myocardium, acetylcholine (10−9 to 10−3 M) elicited a biphasic inotropic effect (a decrease in the lower and an increase in the higher concentration range) in atrial and a positive inotropic effect in ventricular trabeculae. However,

Spontaneous Lipid Binding to the Nicotinic Acetylcholine Receptor in a Native Membrane [PDF]
The nicotinic acetylcholine receptor (nAChR) and other pentameric ligand-gated ion channels (pLGICs) are native to neuronal membranes with an unusual lipid composition. While it is well-established that these receptors can be significantly modulated by lipids, the underlying mechanisms have been primarily studied in model membranes with only a few ...

Muscarinic receptor oligomerization [PDF]
G protein-coupled receptors (GPCRs) have been classically described as monomeric entities that function by binding in a 1:1 stoichiometric ratio to both ligand and downstream signalling proteins.

Human M3 muscarinic acetylcholine receptor protein-protein interactions: roles in receptor signaling and regualation [PDF]
Muscarinic acetylcholine receptors (mAChRs) have been shown to mediate various functions in the central and peripheral nervous systems. These include modulation of exocrine glandular secretion, vasodilatation and smooth muscle contraction, cell proliferation or survival, neural development and synaptic plasticity.

Allosteric interactions at the M3 muscarinic acetylcholine receptor
The extracellular loops of muscarinic acetylcholine receptors are predicted to play a role in the binding and regulation of allosteric modulators. Furthermore, the sequence of the five subtypes of muscarinic receptors shows a large degree of diversity in this region.
