Neuromodulation of Persistent Activity and Working Memory Circuitry in Primate Prefrontal Cortex by Muscarinic Receptors

Frontiers in Neural Circuits, 2021
Neuromodulation by acetylcholine plays a vital role in shaping the physiology and functions of cerebral cortex. Cholinergic neuromodulation influences brain-state transitions, controls the gating of cortical sensory stimulus responses, and has been shown

G Protein–Coupled Receptors in Olfactory Signaling and Related Disorders: Mechanisms and Therapeutic Implications

Sensory Neuroscience, EarlyView.
This schematic highlights GPCRs as the central hub of olfactory signaling in health and disease. The central GPCR shows odorant activation and downstream pathways. Surrounding quadrants illustrate four GPCR‐mediated themes: odor perception and adaptation, mucosal immunity and regeneration, memory consolidation via neural circuits, and GPCR‐related ...

The M2 Muscarinic G-protein-coupled Receptor Is Voltage-sensitive [PDF]

Journal of Biological Chemistry, 2003
G-protein coupled receptors are not considered to exhibit voltage sensitivity. Here, using Xenopus oocytes, we show that the M2 muscarinic receptor (m2R) is voltage-sensitive. The m2R-mediated potassium channel (GIRK) currents were used to assay the activity of m2R.

Thrombin Protease-activated Receptor-1 Signals through Gq- and G13-initiated MAPK Cascades Regulating c-Jun Expression to Induce Cell Transformation [PDF]

, 2003
Although the ability of G protein-coupled receptors to stimulate normal and aberrant cell growth has been intensely investigated, the precise nature of the molecular mechanisms underlying their transforming potential are still not fully understood.

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

Allergy, EarlyView.
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.

Muscarinic receptor oligomerization [PDF]

, 2018
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.

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, EarlyView.
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

Altered muscarinic and nicotinic receptor densities in cortical and subcortical brain regions in Parkinson's disease [PDF]

, 1993
Muscarinic and nicotinic cholinergic receptors and choline acetyltransferase activity were studied in postmortem brain tissue from patients with histopathologically confirmed Parkinson's disease and matched control subjects.

Adreno-Muscarinic Synergy of Contractile Responses From Human Hyperplastic Prostate [PDF]

International Neurourology Journal
Purpose Adreno-muscarinic synergy, a supra-additional contractile response to simultaneous application of α-adrenoreceptor and muscarinic receptor agonists, is a feature of several lower urinary tract regions that have dual sympathetic and ...

Test–retest reliability of Doppler ultrasound‐based leg blood flow assessments during exercise in patients with chronic obstructive pulmonary disease

Experimental Physiology, EarlyView.
Abstract Doppler ultrasound may be used to assess leg blood flow (Q̇leg${{\dot{Q}}_{{\mathrm{leg}}}}$), but the reliability of this method remains unexplored in patients with chronic obstructive pulmonary disease (COPD), where between‐subject variability may be larger than healthy due to peripheral vascular changes.
