Downstream Signaling of Muscarinic M4 Receptors Is Regulated by Receptor Density and Cellular Environment

open access: yesPharmacology Research &Perspectives, Volume 13, Issue 3, June 2025.
ABSTRACT Multiple muscarinic M4 receptor modulators are currently advancing in clinical development for the treatment of positive symptoms in schizophrenia, including agonists and positive allosteric modulators. Considering the importance of comprehending M4 receptor pharmacology for these therapeutic applications, this study investigates M4 receptor ...

A tight coupling between β\u3csub\u3e2\u3c/sub\u3eY97 and β\u3csub\u3e2\u3c/sub\u3eF200 of the GABA\u3csub\u3eA\u3c/sub\u3e receptor mediates GABA binding [PDF]

open access: yes, 2011
The GABAA receptor is an oligopentameric chloride channel that is activated via conformation changes induced upon the binding of the endogenous ligand, GABA, to the extracellular inter-subunit interfaces. Although dozens of amino acid residues at the α/β

Dissecting the Functions of Conserved Prolines within Transmembrane Helices of the D2 Dopamine Receptor [PDF]

open access: yes, 2011
G protein-coupled receptors (GPCRs) contain a number of conserved proline residues in their transmembrane helices, and it is generally assumed these play important functional and/or structural roles.

Differences in the Inflammatory Response and Corticoid Responsiveness of Human Lung Macrophages and Parenchymal Explants Exposed to Cigarette Smoke Extracts

open access: yesBasic &Clinical Pharmacology &Toxicology, Volume 136, Issue 6, June 2025.
ABSTRACT Smoking is the main cause of chronic obstructive pulmonary disease (COPD) and is associated with corticosteroid resistance. Given the paucity of data on human lung preparations, macrophages (LMs), and parenchymal explants (LPEs) were exposed to cigarette smoke extracts (CSE) in the presence or absence of lipopolysaccharide (LPS). Moreover, LMs
