The Impact of Muscarinic Antagonism on Psychosis-Relevant Behaviors and Striatal [11C] Raclopride Binding in Tau Mouse Models of Alzheimer’s Disease

open access: yesBiomedicines, 2023
Psychosis that occurs over the course of Alzheimer’s disease (AD) is associated with increased caregiver burden and a more rapid cognitive and functional decline.

Long-term activation upon brief exposure to xanomleline is unique to M1 and M4 subtypes of muscarinic acetylcholine receptors. [PDF]

open access: yesPLoS ONE, 2014
Xanomeline is an agonist endowed with functional preference for M1/M4 muscarinic acetylcholine receptors. It also exhibits both reversible and wash-resistant binding to and activation of these receptors.

Activation of Muscarinic M1 Acetylcholine Receptors Induces Long-Term Potentiation in the Hippocampus [PDF]

open access: yes, 2015
Muscarinic M1 acetylcholine receptors (M1Rs) are highly expressed in the hippocampus, and their inhibition or ablation disrupts the encoding of spatial memory.

M4 Muscarinic Receptors and Locomotor Activity Regulation

open access: yesPhysiological Research, 2017
M4 muscarinic receptors (M4 MR) represent a subfamily of G-protein coupled receptors serving a substantial role in spontaneous locomotor activity regulation, cognition and modulation of cholinergic system. With increasing body of literature discussing the role of M4 MR some controversies arose.

The muscarinic M4 acetylcholine receptor exacerbates symptoms of movement disorders

open access: yesBiochemical Society Transactions, 2023
Barbeau's seesaw hypothesis of dopamine-acetylcholine balance has predominated movement disorders literature for years. Both the simplicity of the explanation and the matching efficacy of anticholinergic treatment in movement disorders seem to support this hypothesis.

Spirocyclic Diamine Scaffolds for Medicinal Chemistry

open access: yesHelvetica Chimica Acta, Volume 109, Issue 1, January 2026.
Here we enumerated 391 spirocyclic diamine drug scaffolds with ring sizes four to eight and found that most of them are unknown. We prepared four novel such spirocycles and discovered a micromolar inhibitor of the M4 muscarinic receptor. ABSTRACT Medicinal chemistry requires the exploration of structurally diverse compound families to expand the ...

A Dopamine-Acetylcholine Cascade: Simulating Learned and Lesion-Induced Behavior of Striatal Cholinergic Interneurons [PDF]

open access: yes, 2007
The "teaching signal" that modulates reinforcement learning at cortico-striatal synapses may be a sequence composed of an adaptively scaled DA burst, a brief ACh burst, and a scaled ACh pause.

Modulation of c-Jun NH2-Terminal (JNK) by Cholinergic Autoantibodies from Patients with Sjögren’s Syndrome [PDF]

open access: yes, 2011
Background: We wanted to determine (via an immunopharmacological approach) whether the c-Jun NH2 terminal kinase (JNK) cascade is phosphorylated in the submandibular gland by carbachol and cholinergic autoantibodies (IgG) present in the sera of patients ...

Neurons in a Dish: A Review of In Vitro Cell Models for Studying Neurogenesis

open access: yesJournal of Neurochemistry, Volume 170, Issue 1, January 2026.
Different in vitro cell models are valuable to study the different steps of neurogenesis, from the proliferation of neural stem and progenitor cells to the maturation of neurons. Pluripotent stem cells (including embryonic stem cells and induced pluripotent stem cells), immortalized human neuroblastoma cell lines (SH‐SY5Y, IMR‐32), and primary brain ...

Muscarinic acetylcholine receptor M1 and M3 subtypes mediate acetylcholine-induced endothelium-independent vasodilatation in rat mesenteric arteries

open access: yesJournal of Pharmacological Sciences, 2016
The present study investigated pharmacological characterizations of muscarinic acetylcholine receptor (AChR) subtypes involving ACh-induced endothelium-independent vasodilatation in rat mesenteric arteries.
