Autoantibodies to muscarinic acetylcholine receptors found in patients with primary biliary cirrhosis

BMC Gastroenterology, 2010
Background Autoantibodies to the human muscarinic acetylcholine receptor of the M3 type (hmAchR M3) have been suggested to play an etiopathogenic role in Sjögren's syndrome.

Multi‐Omics Reveals Dysregulated Neurotransmitter Systems in Aging and CNS Disorders

Aging Cell, Volume 25, Issue 5, May 2026.
Integrating large‐scale human snRNA‐seq, spatial transcriptomics, and cerebral organoid datasets reveals cell‐type‐specific neurotransmitter‐system remodeling across aging and CNS disorders. Shared and disease‐specific NTS alterations highlight candidate mechanisms, sex differences, and exploratory discriminatory signals that may guide mechanistic ...

Signaling Bias and Antagonism of Pilocarpine for M3 Muscarinic Acetylcholine Receptor

The FASEB Journal, 2018
Pilocarpine is a prototypical drug used to treat glaucoma and dry mouth since the 19 th century and classified as either a full or partial muscarinic agonist. Here, we report several unexpected results pertaining to its interaction with its main therapeutic target ‐ muscarinic M3 receptor ...

Acetylcholine Release Inhibits Distinct Excitatory Inputs Onto Hippocampal CA1 Pyramidal Neurons via Different Cellular and Network Mechanisms

Frontiers in Cellular Neuroscience, 2019
In hippocampal CA1, muscarinic acetylcholine (ACh) receptor (mAChR) activation via exogenous application of cholinergic agonists has been shown to presynaptically inhibit Schaffer collateral (SC) glutamatergic inputs in stratum radiatum (SR), and ...

Acetylcholine From Solitary Chemosensory Cell, Not Neuron, Regulates Basal Cell Fate Driving Eosinophilic Chronic Rhinosinusitis With Nasal Polyps

Allergy, Volume 81, Issue 5, Page 1617-1634, May 2026.
This study identifies that Ach levels are elevated in eCRSwNP and primarily released from SCCs rather than neurons. Ach induces epithelial remodeling in eCRSwNP by binding to M1R/M3R and activating YAP signaling in basal cells, driving basal cell hyperplasia and abnormal differentiation. Blocking M1R/M3R with TB inhibits eCRSwNP progression.

Association Between Cholinesterase Inhibitor‐Overactive Bladder Antimuscarinic Prescribing Cascade and Risk of Delirium and Falls Among Individuals Living With Dementia

Journal of the American Geriatrics Society, Volume 74, Issue 5, Page 1314-1325, May 2026.
ABSTRACT Background Prescribing cascades occur when cholinesterase inhibitor (ChEI)‐induced urinary incontinence is misinterpreted as a new condition, leading to overactive bladder (OAB) antimuscarinic initiation. We evaluated whether the ChEI‐OAB antimuscarinic prescribing cascade was associated with delirium or falls compared with mirabegron in older

Towards Mechanism‐Informed Treatments for Mental Health

Journal of Neurochemistry, Volume 170, Issue 5, May 2026.
Neuropsychiatric disorders impose a major global health burden, and current treatments, which historically mostly targeted dopamine and serotonin dysfunctions, often provide only partial, symptomatic relief. This review highlights emerging evidence that additional neuromodulator systems, including acetylcholine, norepinephrine, and endocannabinoids ...

Dysregulation of CD39/Ectonucleoside Triphosphate Diphosphohydrolase 1 Causes Urinary Bladder Dysfunction with Abnormal Smooth Muscle Contractility

The FASEB Journal, Volume 40, Issue 7, 15 April 2026.
Abnormal extracellular ATP levels cause lower urinary tract symptoms (LUTS). Here, we demonstrate that overexpression of ENTPD1 (CD39TG)—an ATP/ADP converting enzyme—reduces voiding frequency while increasing void volume. Conversely, ENTPD1 deficiency results in frequent, small‐volume voiding.

Desensitization of the m3-muscarinic acetylcholine-receptor in the smooth muscle and the intracellular signal transduction.

Folia Pharmacologica Japonica, 1994
Desensitization of the m3-muscarinic acetylcholine-receptor in the smooth muscle of the digestive tract is discussed together with the changes in intracellular signal transduction. Isolated single cells that show an all-or-none contractile response to acetylcholine were desensitized by treatment with 0.1 mM acetylcholine for 10 min, resulting in an ...

Muscarinic cannabinoid suppression of excitation, a novel form of coincidence detection

Pharmacological Research
Δ9-tetrahydrocannabinol (THC), the chief psychoactive ingredient of cannabis, acts in the brain primarily via cannabinoid CB1 receptors. These receptors are implicated in several forms of synaptic plasticity – depolarization-induced suppression of ...
