Understanding the role of the M1 muscarinic receptor in the propagation of tau as a pathology of Alzheimer's disease [PDF]

open access: yesAlzheimers Dement
Abstract Background Neurofibrillary tangles (NFTs) composed of hyperphosphorylated tau are a hallmark of Alzheimer's disease (AD). While NFT propagation correlates with disease progression, the underlying molecular mechanisms are not well understood. Loss of cholinergic neurons and disrupted cholinergic signalling also occurs throughout AD.

Neuromodulation of Persistent Activity and Working Memory Circuitry in Primate Prefrontal Cortex by Muscarinic Receptors

open access: yesFrontiers 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

Histamine H1 Receptor Down-Regulation Mediated by M3 Muscarinic Acetylcholine Receptor Subtype

open access: yesJournal of Pharmacological Sciences, 2004
Heterologous down-regulation of histamine H1 receptor (H1R) mediated by muscarinic acetylcholine receptor subtype was investigated using five kinds of Chinese hamster ovary (CHO) cells stably co-expressing the human H1R and one of the five (M1 –M5 ...

Bitopic binding mode of an M1 muscarinic acetylcholine receptor agonist associated with adverse clinical trial outcomes [PDF]

open access: yes, 2018
The realisation of the therapeutic potential of targeting the M1 muscarinic acetylcholine receptor (M1 mAChR) for the treatment of cognitive decline in Alzheimer's disease has prompted the discovery of M1 mAChR ligands showing efficacy in alleviating ...

Vitamin E can compensate the density of M1 receptors in the hippocampus of scopolamine-treated rats

open access: yesFolia Neuropathologica, 2018
M1 muscarinic receptor plays a fundamental role in memory and is closely associated with Alzheimer’s disease (AD); it has long been assumed as a therapeutic goal. By activating of the cholinergic receptor vitamin E helps with memory retention.

Synthesis and pharmacological profiling of analogues of benzyl quinolone carboxylic acid (BQCA) as allosteric modulators of the M1 muscarinic receptor [PDF]

open access: yes, 2013
Established therapy in Alzheimer’s disease involves potentiation of the endogenous orthosteric ligand, acetylcholine, at the M1 muscarinic receptors found in higher concentrations in the cortex and hippocampus.

Enhanced muscarinic M1 receptor gene expression in the corpus striatum of streptozotocin-induced diabetic rats

open access: yesJournal of Biomedical Science, 2009
Acetylcholine (ACh), the first neurotransmitter to be identified, regulate the activities of central and peripheral functions through interactions with muscarinic receptors. Changes in muscarinic acetylcholine receptor (mAChR) have been implicated in the
