Muscarinic Agonist-Mediated Heterologous Desensitization in Isolated Ileum Requires Activation of Both Muscarinic M2 and M3 Receptors [PDF]

, 2004
We investigated the subtypes of the muscarinic receptor mediating short-term heterologous desensitization in the isolated ileum. Treatment of the ileum from C57BL/6 mice with acetylcholine (30 μM) for 20 min caused a subsequent decrease in contractile ...

M3 Muscarinic Acetylcholine Receptor-Mediated Signaling Is Regulated by Distinct Mechanisms

Molecular Pharmacology, 2008
We have used RNA interference previously to demonstrate that G protein-coupled receptor kinase 2 (GRK2) regulates endogenously expressed H1 histamine receptor in human embryonic kidney 293 cells. In this report, we investigate the regulation of endogenously expressed M(3) muscarinic acetylcholine receptor (M(3) mAChR).

Arrestin‐centred interactions at the membrane and their conformational determinants

British 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

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

Journal 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.

Selective expression of muscarinic acetylcholine receptor subtype M3 by mouse type III taste bud cells

Pflügers Archiv: European Journal of Physiology, 2016
Each taste bud cell (TBC) type responds to a different taste. Previously, we showed that an unidentified cell type(s) functionally expresses a muscarinic acetylcholine (ACh) receptor subtype, M3, and we suggested the ACh-dependent modification of its ...

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

British 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

Pharmacological Characterization of Itch-Associated Response Induced by Repeated Application of Oxazolone in Mice

Journal of Pharmacological Sciences, 2010
We investigated pharmacological characteristics of the itch-associated response to chronic dermatitis induced by 4-ethoxymethylene-2-phenyl-2-oxazolin-5-one (oxazolone) repeated application in mice.

Macrophage TNF-α mediates parathion-induced airway hyperreactivity in guinea pigs. [PDF]

, 2013
Organophosphorus pesticides (OPs) are implicated in human asthma. We previously demonstrated that, at concentrations that do not inhibit acetylcholinesterase activity, the OP parathion causes airway hyperreactivity in guinea pigs as a result of ...

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

British 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
