Ovariectomy reduces cholinergic modulation of excitatory synaptic transmission in the rat entorhinal cortex.

PLoS ONE, 2022
Estrogens are thought to contribute to cognitive function in part by promoting the function of basal forebrain cholinergic neurons that project to the hippocampus and cortical regions including the entorhinal cortex.

Central Executive Dysfunction and Deferred Prefrontal Processing in Veterans with Gulf War Illness. [PDF]

, 2013
Gulf War Illness is associated with toxic exposure to cholinergic disruptive chemicals. The cholinergic system has been shown to mediate the central executive of working memory (WM).

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.

Activation of protein tyrosine kinase PYK2 by the m1 muscarinic acetylcholine receptor [PDF]

Proceedings of the National Academy of Sciences, 1998
Several G protein-coupled receptors are known to direct the tyrosine phosphorylation, and in some cases the activation, of diverse tyrosine kinases. Using a stable cell line approach, we characterize the activation of PYK2, a tyrosine kinase structurally related to focal adhesion kinase, by the G protein-coupled m1 muscarinic acetylcholine receptor. We

FRET-based detection of M1 muscarinic acetylcholine receptor activation by orthosteric and allosteric agonists.

PLoS ONE, 2012
Background and objectiveMuscarinic acetylcholine receptors (mAChRs) are 7-transmembrane, G protein-coupled receptors that regulate a variety of physiological processes and represent potentially important targets for therapeutic intervention.

Cell-Type Specific Neuromodulation of Excitatory and Inhibitory Neurons via Muscarinic Acetylcholine Receptors in Layer 4 of Rat Barrel Cortex

Frontiers in Neural Circuits, 2022
The neuromodulator acetylcholine (ACh) plays an important role in arousal, attention, vigilance, learning and memory. ACh is released during different behavioural states and affects the brain microcircuit by regulating neuronal and synaptic properties ...

Evaluation of preclinical antipsychotic models used to support first‐in‐human clinical trials

British Journal of Pharmacology, EarlyView.
Abstract Schizophrenia is regarded as a complex and heterogeneous psychiatric disorder, characterised by diverse symptoms and comorbidities, which complicate both clinical management and drug development. Current pharmacological treatment, primarily based on dopamine D2 receptor antagonism or partial agonism, which has not markedly progressed since the

A molecular basis for selective antagonist destabilization of dopamine D3 receptor quaternary organization [PDF]

, 2017
The dopamine D3 receptor (D3R) is a molecular target for both first-generation and several recently-developed antipsychotic agents. Following stable expression of this mEGFP-tagged receptor, Spatial Intensity Distribution Analysis indicated that a ...

Further Insights Into Anticholinergic Action Informed by Japanese Anticholinergic Risk Scale

Geriatrics &Gerontology International, EarlyView.
ABSTRACT The increased anticholinergic burden caused by medications in older adults is one of the adverse drug reactions of particular concern, as it can exacerbate the onset of geriatric syndromes or induce cognitive dysfunction, and is also related to the issue of polypharmacy.
