The M1 muscarinic acetylcholine receptor subtype is important for retinal neuron survival in aging mice

Scientific Reports, 2019
Muscarinic acetylcholine receptors have been implicated as potential neuroprotective targets for glaucoma. We tested the hypothesis that the lack of a single muscarinic receptor subtype leads to age-dependent neuron reduction in the retinal ganglion cell

Spinal cord regeneration by modulating bone marrow with neurotransmitters and Citicholine: Analysis at micromolecular level

Biomedical Journal, 2017
Background: Spinal cord injury results in disruption of brain-spinal cord fibre connectivity, leading to progressive tissue damage at the site of injury and resultant paralysis of varying degrees.

Safety, pharmacokinetics and exploratory pro-cognitive effects of HTL0018318, a selective M1 receptor agonist, in healthy younger adult and elderly subjects: a multiple ascending dose study

Alzheimer’s Research & Therapy, 2021
Background The cholinergic system and M1 receptor remain an important target for symptomatic treatment of cognitive dysfunction. The selective M1 receptor partial agonist HTL0018318 is under development for the symptomatic treatment of Dementia’s ...

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.

Cooperative Glutamatergic and Cholinergic Mechanisms Generate Short-Term Modifications of Synaptic Effectiveness in Prepositus Hypoglossi Neurons [PDF]

, 2005
To maintain horizontal eye position on a visual target after a saccade, extraocular motoneurons need a persistent (tonic) neural activity, called "eye-position signal," generated by prepositus hypoglossi (PH) neurons.

Muscarinic modulation of M and h currents in gerbil spherical bushy cells.

PLoS ONE, 2020
Descending cholinergic fibers innervate the cochlear nucleus. Spherical bushy cells, principal neurons of the anterior part of the ventral cochlear nucleus, are depolarized by cholinergic agonists on two different time scales.

Rationale for Selective Muscarinic Receptor Agonists as Candidates for the Management of Cognitive and Neuropsychiatric Symptoms in Alzheimer's Disease [PDF]

Alzheimers Dement
Abstract Background Cognitive impairment and neuropsychiatric symptoms, including psychosis, are fundamental features of Alzheimer's disease (AD) and related dementias. Currently treatments for these symptoms have efficacy, safety, and tolerability limitations; new treatments with novel mechanisms are needed.

Distinct agonist regulation of muscarinic acetylcholine M2-M3 heteromers and their corresponding homomers [PDF]

, 2015
Each subtype of the muscarinic receptor family of G protein-coupled receptors is activated by similar concentrations of the neurotransmitter acetylcholine or closely related synthetic analogs such as carbachol. However, pharmacological selectivity can be

Relationship between muscarinic M1 receptor binding and cognition in medication-free subjects with psychosis

NeuroImage: Clinical, 2018
Background: It is still unclear which underlying mechanisms are involved in cognitive deficits of psychotic disorders. Pro-cognitive effects of muscarinic M1 receptor agonists suggest alterations in M1 receptor functioning may modulate these symptoms ...

Cross-diagnostic determinants of cognitive functioning: the muscarinic cholinergic receptor as a model system

Translational Psychiatry, 2023
Cognitive impairment is a predictor of disability across different neuropsychiatric conditions, and cognitive abilities are also strongly related to educational attainment and indices of life success in the general population.
