Carbachol Induces Ca2+-Dependent Contraction via Muscarinic M2 and M3 Receptors in Rat Intestinal Subepithelial Myofibroblasts

open access: yesJournal of Pharmacological Sciences, 2009
.: Intestinal myofibroblasts (IMFs) that exist adjacent to the basement membrane of intestines have contractility and contribute to physical barriers of the intestine.

Multiple Residues in the Second Extracellular Loop Are Critical for M3 Muscarinic Acetylcholine Receptor Activation [PDF]

open access: yes, 2007
Recent studies suggest that the second extracellular loop (o2 loop) of bovine rhodopsin and other class I G protein-coupled receptors (GPCRs) targeted by biogenic amine ligands folds deeply into the transmembrane receptor core where the binding of cis ...

Functional Magnetic Resonance Imaging (fMRI) Signatures of Progression and Phenoconversion in Prodromal Synucleinopathies

open access: yesMovement Disorders, EarlyView.
Abstract Background Isolated rapid eye movement (REM) sleep behavior disorder (iRBD) is a prodromal manifestation of synucleinopathies and provides a critical window to identify early markers of progression to Parkinson's disease (PD) and dementia with Lewy bodies (DLB).

Engineering of three-finger fold toxins creates ligands with original pharmacological profiles for muscarinic and adrenergic receptors. [PDF]

open access: yesPLoS ONE, 2012
Protein engineering approaches are often a combination of rational design and directed evolution using display technologies. Here, we test "loop grafting," a rational design method, on three-finger fold proteins.

Recovery of hippocampal functions and modulation of muscarinic response by electroacupuncture in young diabetic rats [PDF]

open access: yes, 2017
The muscarinic receptor response to acetylcholine regulates the hippocampal-related learning, memory, neural plasticity and the production and processing of the pro-nerve growth factor (proNGF) by hippocampal cells.

Pharmacological and Mechanistic Interventions for Cognitive Impairment Associated With Schizophrenia: A Review of Registered Clinical Trials

open access: yesActa Psychiatrica Scandinavica, EarlyView.
ABSTRACT Background Schizophrenia is characterized by positive, negative, and cognitive symptoms. Current pharmacological treatments often fail to address cognitive deficits. In this review of clinical trials, we aim to identify studies that explore neurobiological (non‐psychological) strategies to address Cognitive Impairment Associated with ...

Cholinergic regulation of mood: from basic and clinical studies to emerging therapeutics. [PDF]

open access: yes, 2019
Mood disorders are highly prevalent and are the leading cause of disability worldwide. The neurobiological mechanisms underlying depression remain poorly understood, although theories regarding dysfunction within various neurotransmitter systems have ...

Inhibition of Connexin43 hemichannels impairs spatial short-term memory without affecting spatial working memory [PDF]

open access: yes, 2016
Astrocytes are active players in higher brain function as they can release gliotransmitters, which are essential for synaptic plasticity. Various mechanisms have been proposed for gliotransmission, including vesicular mechanisms as well as non-vesicular ...

Acetylcholine From Solitary Chemosensory Cell, Not Neuron, Regulates Basal Cell Fate Driving Eosinophilic Chronic Rhinosinusitis With Nasal Polyps

open access: yesAllergy, EarlyView.
This study identifies that Ach levels are elevated in eCRSwNP and primarily released from SCCs rather than neurons. Ach induces epithelial remodeling in eCRSwNP by binding to M1R/M3R and activating YAP signaling in basal cells, driving basal cell hyperplasia and abnormal differentiation. Blocking M1R/M3R with TB inhibits eCRSwNP progression.

The varieties of the psychedelic experience: A preliminary study of the association between the reported subjective effects and the binding affinity profiles of substituted phenethylamines and tryptamines [PDF]

open access: yes, 2018
Classic psychedelics are substances of paramount cultural and neuroscientific importance. A distinctive feature of psychedelic drugs is the wide range of potential subjective effects they can elicit, known to be deeply influenced by the internal state of
