International Journal for Parasitology: Drugs and Drug Resistance, 2023 The physiological significance of metabotropic acetylcholine receptors in parasitic nematodes remains largely unexplored. Here, three different Trichinella spiralis G protein-coupled acetylcholine receptors (TsGAR-1, -2, and -3) were identified in the ...

Boundary lipids of the nicotinic acetylcholine receptor: spontaneous partitioning via coarse-grained molecular dynamics simulation [PDF]
arXiv, 2018 Reconstituted nicotinic acetylcholine receptors (nAChRs) exhibit significant gain-of-function upon addition of cholesterol to reconstitution mixtures, and cholesterol affects organization of nAChRs within domain-forming membranes, but whether nAChR partitions to cholesterol-rich liquid-ordered ("raft" or $l_o$) domains or cholesterol-poor liquid ...

On the excitation of action potentials by protons and its potential implications for cholinergic transmission [PDF]
, 2014 One of the most conserved mechanisms for transmission of a nerve pulse across a synapse relies on acetylcholine. Ever since the Nobel-prize winning works of Dale and Loewi, it has been assumed that acetylcholine - subsequent to its action on a postsynaptic cell - is split into inactive by-products by acetylcholinesterase.

G protein‐coupled receptor‐mediated autophagy in health and disease
British Journal of Pharmacology, EarlyView.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

ERNEST COST action overview on the (patho)physiology of GPCRs and orphan GPCRs in the nervous system
British Journal of Pharmacology, EarlyView.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

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 ...

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 ...

Opening a hydrophobic gate: the nicotinic acetylcholine receptor as an example [PDF]
arXiv, 2009 To what extent must a hydrophobic gate expand for the channel to count as open? We address this question using the nicotinic acetylcholine receptor (nAChR) as the exemplar. The nAChR is an integral membrane protein which forms a cation selective channel gated by neurotransmitter binding to its extracellular domain.

Progress on the development of Class A GPCR‐biased ligands
British Journal of Pharmacology, EarlyView.Class A G protein‐coupled receptors (GPCRs) continue to garner interest for their essential roles in cell signalling and their importance as drug targets. Although numerous drugs in the clinic target these receptors, over 60% GPCRs remain unexploited. Moreover, the adverse effects triggered by the available unbiased GPCR modulators, limit their use and

British Journal of Pharmacology, EarlyView.Background and Purpose Hyoscine butylbromide (HBB) has a low oral (PO) bioavailability. Further, limited data on its activity on non‐gastrointestinal (GI) smooth muscle spasms after oral dosing are available, causing its effects beyond the GI tract to be questioned.
