Structural determinants at the M2 muscarinic receptor modulate the RGS4-GIRK response to pilocarpine by impairment of the receptor voltage sensitivity [PDF]
Membrane potential controls the response of the M2 muscarinic receptor to its ligands. Membrane hyperpolarization increases response to the full agonist acetylcholine (ACh) while decreasing response to the partial agonist pilocarpine.

The dual-site agonist for human M2 muscarinic receptors Iper-8-naphtalimide induces mitochondrial dysfunction in Saccharomyces cerevisiae [PDF]
Glioblastoma is a malignant astrocytic tumor of the brain. A significantly decrease of glioblastoma cell proliferation and survival can be achieved by activating the M2 muscarinic acetylcholine receptor (a G protein-coupled receptor, or GPCR) with two ...

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

Pathogenic Gαo Mutants Drive Dominant GPCR Coupling in GNAO1 Encephalopathies. [PDF]
Mutations in GNAO1, the gene encoding Gαo, are associated with a wide range of neurodevelopmental disorders. In this study, we show that Gαo variants linked to the most severe patient phenotypes fail to disengage from activated Gi/o‐coupled GPCRs, thereby blocking GRK‐mediated receptor phosphorylation and internalization.

Changes in adrenergic and cholinergic receptors on human cerebral vessels. Implications for new therapeutic strategies in Alzheimer's Disease [PDF]
Abstract Background Sporadic cerebral amyloid angiopathy (CAA) occurs as a result of a failure of Intramural Periarterial Drainage (IPAD) of amyloid‐beta (Aβ) along the walls of capillaries and arteries. The motive force for IPAD is provided by the spontaneous contractions of cerebrovascular smooth muscle cells (CVSMC that receive adrenergic and ...

Synergistic mechanisms of medullary cholinergic-serotonergic pathway interactions in regulating neuronal excitability and locomotor activities [PDF]
Medullary serotonergic (5-HT) neurons play a pivotal role in locomotor initiation. While these neurons receive cholinergic innervation, the functional consequences and underlying mechanisms remain poorly understood. Using ePet-EYFP transgenic mice (P3–P6)

Further Insights Into Anticholinergic Action Informed by Japanese Anticholinergic Risk Scale. [PDF]
ABSTRACT The increased anticholinergic burden caused by medications in older adults is one of the adverse drug reactions of particular concern, as it can exacerbate the onset of geriatric syndromes or induce cognitive dysfunction, and is also related to the issue of polypharmacy.
