Simultaneous release of glutamate and acetylcholine from single magnocellular "cholinergic" basal forebrain neurons [PDF]

open access: yes, 2006
Basal forebrain (BF) neurons provide the principal cholinergic drive to the hippocampus and cortex. Their degeneration is associated with the cognitive defects of Alzheimer's disease. Immunohistochemical studies suggest that some of these neurons contain

Association of Different Types of Diabetic Autonomic Neuropathy With Left Ventricular Diastolic Dysfunction in Patients With Type 2 Diabetes: A Cross‐Sectional Study

open access: yesJournal of Diabetes, Volume 17, Issue 7, July 2025.
Severe cardiac autonomic dysfunction (SDNN<50 ms), and diabetic neurogenic bladder are independently associated with LVDD in individuals with T2DM. ABSTRACT Background To investigate the association between different categories of diabetic autonomic neuropathy (DAN) and left ventricular diastolic dysfunction (LVDD) in patients with type 2 diabetes ...

Altered muscarinic and nicotinic receptor densities in cortical and subcortical brain regions in Parkinson's disease [PDF]

open access: yes, 1993
Muscarinic and nicotinic cholinergic receptors and choline acetyltransferase activity were studied in postmortem brain tissue from patients with histopathologically confirmed Parkinson's disease and matched control subjects.

Arrestin‐centred interactions at the membrane and their conformational determinants

open access: yesBritish Journal of Pharmacology, Volume 182, Issue 14, Page 3135-3150, July 2025.
Abstract More than 30 years after their discovery, arrestins are recognised multiprotein scaffolds that play essential roles in G protein‐coupled receptor (GPCR) regulation and signalling. Originally named for their capacity to hinder GPCR coupling to G proteins and facilitate receptor desensitisation, arrestins have emerged as key hubs for a myriad of

Enhanced Conformational Sampling of M2 Muscarinic Acetylcholine Receptor for Designing Selective Allosteric Drugs [PDF]

open access: yesBiophysical Journal, 2013
Muscarinic acetylcholine receptors are members of the superfamily of G-protein coupled receptors (GPCRs) and play critical roles in both the central and parasympathetic nervous systems. They are important drug targets for the treatment of a spectrum of diseases including abnormal heart rate, asthma, chronic obstructive pulmonary disease, Alzheimer's ...

G protein‐coupled receptor‐mediated autophagy in health and disease

open access: yesBritish Journal of Pharmacology, Volume 182, Issue 14, Page 3151-3162, July 2025.
G protein‐coupled receptors (GPCRs) constitute the largest and most diverse superfamily of mammalian transmembrane proteins. These receptors are involved in a wide range of physiological functions and are targets for more than a third of available drugs in the market. Autophagy is a cellular process involved in degrading damaged proteins and organelles

Evidence for Respiratory Neuromodulator Interdependence after Cholinergic Disruption in the Ventral Respiratory Column [PDF]

open access: yes, 2015
Reverse dialysis of the muscarinic receptor antagonist, atropine (ATR, 50 mM), into the pre-Bötzinger Complex region of the ventral respiratory column (VRC) of awake and sleeping goats increases breathing frequency and serotonin (5-HT), substance P (SP),

Binding and functional characterisation of allosteric agonists at M2 muscarinic acetylcholine receptors

open access: yesThe FASEB Journal, 2008
Muscarinic acetylcholine receptors (mAChRs) contain at least one allosteric site that is topographically distinct from the acetylcholine (ACh)‐binding orthosteric site. Although numerous studies have investigated the structural basis of allosteric modulation at these receptors, far less is known about allosteric ligands that activate the receptor in ...

ERNEST COST action overview on the (patho)physiology of GPCRs and orphan GPCRs in the nervous system

open access: yesBritish Journal of Pharmacology, Volume 182, Issue 14, Page 3178-3210, July 2025.
G protein‐coupled receptors (GPCRs) are a large family of cell surface receptors that play a critical role in nervous system function by transmitting signals between cells and their environment. They are involved in many, if not all, nervous system processes, and their dysfunction has been linked to various neurological disorders representing important

Regions of beta 2 and beta 4 responsible for differences between the steady state dose-response relationships of the alpha 3 beta 2 and alpha 3 beta 4 neuronal nicotinic receptors [PDF]

open access: yes, 1995
We constructed chimeras of the rat beta 2 and beta 4 neuronal nicotinic subunits to locate the regions that contribute to differences between the acetylcholine (ACh) dose-response relationships of the alpha 3 beta 2 and alpha 3 beta 4 receptors ...
