ATP and Odor Mixture Activate TRPM5-Expressing Microvillous Cells and Potentially Induce Acetylcholine Release to Enhance Supporting Cell Endocytosis in Mouse Main Olfactory Epithelium

Frontiers in Cellular Neuroscience, 2018
The main olfactory epithelium (MOE) functions to detect odor molecules, provide an epithelial surface barrier, and remove xenobiotics from inhaled air.

Glial cells in the heart: Implications for their roles in health and disease

The Journal of Physiology, Volume 604, Issue 4, Page 1531-1546, 15 February 2026.
Abstract figure legend Schematic representation of cardiac autonomic ganglia within epicardial fat pads (posterior heart surface shown), containing vagal postganglionic neuron cell bodies, associated fibres, and glia. These ganglia receive cholinergic input from vagal preganglionic neurons and adrenergic input from sympathetic postganglionic neurons ...

Gene expression of muscarinic, tachykinin and purinergic receptors in porcine bladder: comparison with cultured cells

Frontiers in Pharmacology, 2013
Urothelial cells, myofibroblasts, and smooth muscle cells are important cell types contributing to bladder function. Multiple receptors including muscarinic (M3/M5), tachykinin (NK1/NK2) and purinergic (P2X1/P2Y6) receptors are involved in bladder motor ...

Reduced Cocaine Self-Administration in Muscarinic M₅Acetylcholine Receptor-Deficient Mice [PDF]

The Journal of Neuroscience, 2005
The reinforcing effects of cocaine have been related to increased extracellular concentrations of dopamine in the ventral striatum. Several studies suggest that M5muscarinic receptors facilitate striatal dopamine release. We tested the hypothesis that the reinforcing effects of cocaine are decreased in M5receptor-deficient mice using chronic ...

Alpha‐Ketoglutarate Regulates Intestinal Motility and Health by OXGR1 in Nitrergic Neuron of Enteric Nervous System

Food Frontiers, Volume 7, Issue 1, January 2026.
ABSTRACT Intestinal health could be affected by intestinal motility, which is controlled by the enteric nervous system. In this study, we found that α‐ketoglutarate (AKG) inhibits intestinal motility and improves intestinal permeability, accompanied by an increased count of intestinal flora.

Cellular responses to stimulation of the M5 muscarinic acetylcholine receptor as seen in murine L cells.

Journal of Biological Chemistry, 1990
The membrane signaling properties of the neuronal type-5 muscarinic acetylcholine receptor (M5 AChR) as expressed in murine L cells were studied. Recipient Ltk- cells responded to ATP acting through a P2-purinergic receptor by increasing phosphoinositide hydrolysis 2-fold but were unresponsive to 17 receptor agonists that are stimulatory in other cells.

Muscarinic—but Not Nicotinic—Acetylcholine Receptors Mediate a Nitric Oxide-Dependent Dilation in Brain Cortical Arterioles: A Possible Role for the M5 Receptor Subtype [PDF]

Journal of Cerebral Blood Flow & Metabolism, 2000
Increases in cortical cerebral blood flow are induced by stimulation of basal forebrain cholinergic neurons. This response is mediated in part by nitric oxide (NO) and reportedly involves both nicotinic and muscarinic receptors, some of which are possibly located in the vessel wall.

Spirocyclic Diamine Scaffolds for Medicinal Chemistry

Helvetica Chimica Acta, Volume 109, Issue 1, January 2026.
Here we enumerated 391 spirocyclic diamine drug scaffolds with ring sizes four to eight and found that most of them are unknown. We prepared four novel such spirocycles and discovered a micromolar inhibitor of the M4 muscarinic receptor. ABSTRACT Medicinal chemistry requires the exploration of structurally diverse compound families to expand the ...

Navigating the Core Challenges of Atropine Therapy in Myopia: A Mechanistic and Clinical Analysis of Dose, Response, and Durability

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Myopia has emerged as a major global public health concern. Atropine, recognized as one of the foremost interventions for myopia control, has been validated for its efficacy and safety through a multitude of clinical studies. This article examines the most recent advancements in understanding atropine’s mechanisms of action, optimizing dosage ...

Regulation of Src family kinases by muscarinic acetylcholine receptors in heterologous cells and neurons

Frontiers in Molecular Neuroscience
Five muscarinic acetylcholine (mACh) receptor subtypes are divided into two classes: the M1 class (M1, M3, and M5) and the M2 class (M2 and M4). The former is coupled to Gq proteins, while the latter is coupled to Gi/o proteins.
