Recovery of hippocampal functions and modulation of muscarinic response by electroacupuncture in young diabetic rats

Scientific Reports, 2017
The muscarinic receptor response to acetylcholine regulates the hippocampal-related learning, memory, neural plasticity and the production and processing of the pro-nerve growth factor (proNGF) by hippocampal cells.

Binding and functional characterisation of allosteric agonists at M2 muscarinic acetylcholine receptors

The FASEB Journal, 2008
Muscarinic acetylcholine receptors (mAChRs) contain at least one allosteric site that is topographically distinct from the acetylcholine (ACh)‐binding orthosteric site. Although numerous studies have investigated the structural basis of allosteric modulation at these receptors, far less is known about allosteric ligands that activate the receptor in ...

Colorectal Neoplasia Pathogenesis in Normal Appearing Colonic Mucosa ‐A Perspective With Focus on Eicosanoid Signaling Pathways

Cancer Medicine, Volume 14, Issue 18, September 2025.
ABSTRACT Colorectal cancer (CRC) is a major cause of cancer‐related mortality, especially in the Western world, and its incidence is expected to increase in the years to come. Prevention and early detection are key strategies to improve CRC morbidity and mortality.

Acetylcholine regulates the melanogenesis of retinal pigment epithelia cells via a cAMP-dependent pathway: A non-neuronal function of cholinergic system in retina

Heliyon
The turnover rate of melanogenesis in retinal pigment epithelium (RPE) and its molecular signaling remain unclear. This study aimed to investigate the role of cholinergic signaling in the process of melanogenesis of cultured RPE cells.

Enhanced Conformational Sampling of M2 Muscarinic Acetylcholine Receptor for Designing Selective Allosteric Drugs [PDF]

Biophysical Journal, 2013
Muscarinic acetylcholine receptors are members of the superfamily of G-protein coupled receptors (GPCRs) and play critical roles in both the central and parasympathetic nervous systems. They are important drug targets for the treatment of a spectrum of diseases including abnormal heart rate, asthma, chronic obstructive pulmonary disease, Alzheimer's ...

Differentiated Presynaptic Input to OLMɑ2 Cells Along the Hippocampal Dorsoventral Axis: Implications for Hippocampal Microcircuit Function

Hippocampus, Volume 35, Issue 5, September 2025.
ABSTRACT The dorsal and ventral hippocampus have distinct processing properties, but it remains unclear if interneuron subtypes differ in connectivity along the dorsoventral axis. Oriens lacunosum‐moleculare (OLM) interneurons, identified by the Chrna2 gene, are known to regulate memory processes differently along this axis. OLMɑ2 cells bidirectionally

Central Pattern Generators in Spinal Cord Injury: Mechanisms, Modulation, and Therapeutic Strategies for Motor Recovery

JOR SPINE, Volume 8, Issue 3, September 2025.
This study explores the role of Central Pattern Generators (CPGs) in locomotor recovery after spinal cord injury (SCI). It examines CPG organization, function, and modulation through amino acids, biogenic amines, and acetylcholine. Therapeutic strategies, including pharmacological, electrical, and optogenetic approaches, are reviewed, alongside current

β3‐Adrenoceptor Agonist Effects on the Urinary Bladder Beyond Detrusor Relaxation

Neurourology and Urodynamics, Volume 44, Issue 7, Page 1498-1502, September 2025.
ABSTRACT Aims β3‐Adrenoceptor agonists such as mirabegron or vibegron reach pharmacokinetic steady‐state within a few days. However, maximum improvements in symptoms of the overactive bladder syndrome are reached at time points later than 4 weeks, that is, detrusor smooth muscle relaxation cannot fully explain clinical effects.

Swimming against the tide: investigations of the C-Bouton synapse

Frontiers in Neural Circuits, 2014
C-boutons are important cholinergic modulatory loci for state-dependent alterations in motoneuron firing rate. Type 2 muscarinic acetylcholine (m2) receptors are concentrated postsynaptic to C-boutons, and m2 receptor activation increases motoneuron ...

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 ...
