Synergistic mechanisms of medullary cholinergic-serotonergic pathway interactions in regulating neuronal excitability and locomotor activities [PDF]

Communications Biology
Medullary serotonergic (5-HT) neurons play a pivotal role in locomotor initiation. While these neurons receive cholinergic innervation, the functional consequences and underlying mechanisms remain poorly understood. Using ePet-EYFP transgenic mice (P3–P6)

The potential of muscarinic M1 and M4 receptor activators for the treatment of cognitive impairment associated with schizophrenia

Frontiers in Psychiatry
Cognitive impairment is a core symptom of schizophrenia and a major determinant of poor long-term functional outcomes. Despite considerable efforts, we do not yet have any approved pharmacological treatments for cognitive impairment associated with ...

Molecular Mechanisms of Bitopic Ligand Engagement with the M1 Muscarinic Acetylcholine Receptor* [PDF]

Journal of Biological Chemistry, 2014
Background: Bitopic ligands bind concomitantly to orthosteric and allosteric receptor sites. Results: Residues affecting binding and biased signaling of the selective agonists TBPB and 77-LH-28-1 were identified at the M1 muscarinic receptor. Conclusion:

M1 muscarinic acetylcholine receptor in Alzheimer’s disease [PDF]

Neuroscience Bulletin, 2014
The degeneration of cholinergic neurons and cholinergic hypofunction are pathologies associated with Alzheimer's disease (AD). Muscarinic acetylcholine receptors (mAChRs) mediate acetylcholine-induced neurotransmission and five mAChR subtypes (M1-M5) have been identified.

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

Characterization of the positive and negative inotropic effects of acetylcholine in the human myocardium [PDF]

, 1995
In the human isolated myocardium, acetylcholine (10−9 to 10−3 M) elicited a biphasic inotropic effect (a decrease in the lower and an increase in the higher concentration range) in atrial and a positive inotropic effect in ventricular trabeculae. However,

Clinical and Preclinical Evidence for M1 Muscarinic Acetylcholine Receptor Potentiation as a Therapeutic Approach for Rett Syndrome

Neurotherapeutics, 2022
Rett syndrome (RTT) is a neurodevelopmental disorder that is characterized by developmental regression, loss of communicative ability, stereotyped hand wringing, cognitive impairment, and central apneas, among many other symptoms.

Further Insights Into Anticholinergic Action Informed by Japanese Anticholinergic Risk Scale. [PDF]

Geriatr Gerontol Int
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.
