Vibrational spectroscopy analysis of ligand efficacy in human M2 muscarinic acetylcholine receptor (M2R)

Communications Biology, 2021
Katayama et al. report a vibrational spectroscopic study using ATR–FTIR of the human M2 muscarinic acetylcholine receptor (M2R). Their work involves an extensive comparison of agonists, antagonists, and inverse agonists, in which they show that they C ...

Basic and Clinical Aspects of Non-neuronal Acetylcholine: Expression of Non-neuronal Acetylcholine in Lung Cancer Provides a New Target for Cancer

Journal of Pharmacological Sciences, 2008
Lung cancer is the leading cause of cancer death worldwide and new treatment strategies are clearly needed. The recent discovery that lung and other cancers synthesize and secrete acetylcholine (ACh) which acts as an autocrine growth factor suggests that

Differing time dependencies of object recognition memory impairments produced by nicotinic and muscarinic cholinergic antagonism in perirhinal cortex [PDF]

, 2011
The roles of muscarinic and nicotinic cholinergic receptors in perirhinal cortex in object recognition memory were compared. Rats' discrimination of a novel object preference test (NOP) test was measured after either systemic or local infusion into the ...

Cholinergic Regulation of Orexin/Hypocretin Neurons Through M3Muscarinic Receptor in Mice

Journal of Pharmacological Sciences, 2008
The cholinergic system plays an important role in regulation of arousal and REM sleep. In the present study, we showed that a muscarinic receptor agonist, carbachol (CCh), activates almost 20% of orexin-producing neurons (orexin neurons), which play a ...

Clinical Factors Associated With Dose Escalation of Solifenacin for the Treatment of Overactive Bladder in Real Life Practice [PDF]

International Neurourology Journal, 2014
PurposeTo determine the baseline clinical characteristics associated with dose escalation of solifenacin in patients with overactive bladder (OAB).MethodsWe analyzed the data of patients with OAB (micturition frequency ≥8/day and urgency ≥1/day) who were

Selective M3 Muscarinic Receptor Antagonist Inhibits Small-Cell Lung Carcinoma Growth in a Mouse Orthotopic Xenograft Model

Journal of Pharmacological Sciences, 2011
.: In small cell lung carcinoma (SCLC), acetylcholine (ACh) is synthesized and secreted, and it acts as an autocrine growth factor through activation of its receptors, muscarinic receptor (mAChR) and nicotinic receptor (nAChR). Alteration of tumor growth

Carbachol increases intracellular free calcium concentrations in human granulosa-lutein cells [PDF]

, 1992
We investigated whether the stimulation of human granulosa-lutein cells with muscarinic and nicotinic receptor agonists can cause increases in intracellular free calcium (Ca2+), using Fura-2 microfluorimetry.

Muscarinic Acetylcholine Type 1 Receptor Activity Constrains Neurite Outgrowth by Inhibiting Microtubule Polymerization and Mitochondrial Trafficking in Adult Sensory Neurons

Frontiers in Neuroscience, 2018
The muscarinic acetylcholine type 1 receptor (M1R) is a metabotropic G protein-coupled receptor. Knockout of M1R or exposure to selective or specific receptor antagonists elevates neurite outgrowth in adult sensory neurons and is therapeutic in diverse ...

The structural study of mutation-induced inactivation of human muscarinic receptor M4

IUCrJ, 2020
Human muscarinic receptor M4 belongs to the class A subfamily of the G-protein-coupled receptors (GPCRs). M4 has emerged as an attractive drug target for the treatment of Alzheimer's disease and schizophrenia.
