Protective Potentials of Natural Products Against Vascular Dementia: A Comprehensive Review of Experimental Studies

Phytotherapy Research, EarlyView.
ABSTRACT Vascular dementia (VaD), accounting for up to 20% of dementia cases globally, is primarily driven by chronic cerebral hypoperfusion (CCH), which leads to progressive cognitive impairment. Despite the increasing prevalence of VaD, effective treatments remain limited.

Allosteric modulators targeting CNS muscarinic receptors [PDF]

, 2018
Muscarinic acetylcholine receptors are G protein-coupled receptors (GPCRs) which are broadly expressed in the central nervous system (CNS) and other tissues in the periphery.

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.

Clinical Outcomes and Acute Exacerbation Incidence in Combined Pulmonary Fibrosis and Emphysema

Respirology, EarlyView.
This multicentre prospective study of 1016 patients demonstrated that CPFE, defined as ≥ 5% emphysema on visual CT assessment, identified a high‐risk phenotype with significantly worse 5‐year survival compared to non‐CPFE IIP patients (51.4% vs. 63.1%) and COPD patients (51.4% vs. 84.0%) and higher acute exacerbation incidence, validating international

Selective M3 Muscarinic Receptor Antagonist Inhibits Small-Cell Lung Carcinoma Growth in a Mouse Orthotopic Xenograft Model

Journal of Pharmacological Sciences, 2011
.: In small cell lung carcinoma (SCLC), acetylcholine (ACh) is synthesized and secreted, and it acts as an autocrine growth factor through activation of its receptors, muscarinic receptor (mAChR) and nicotinic receptor (nAChR). Alteration of tumor growth

Inhaled Corticosteroid Escalation After a Single Moderate Exacerbation in COPD: Differential Benefit by Exacerbation Subtype

Respirology, EarlyView.
We tested whether ICS escalation after a single moderate COPD exacerbation improved outcomes according to exacerbation treatment phenotype. ICS reduced future exacerbations only in steroid‐treated events, not antibiotic‐treated events. This study supports phenotype‐guided escalation after one moderate exacerbation, avoiding overtreatment with precise ...

Pharmacological investigations on muscarinic and P2 receptor subtypes : pharmacological charakterisation of the stereoisomers of glycopyrronium bromide and their tertiary analogues and evaluation of the isolated guinea-pig and rat ileal longitudinal [PDF]

, 2003
Die Beschäftigung mit Muskarinrezeptoren reicht bis in das vergangene Jahrhundert zurück als, in Folge der verschiedenen Wirkungen des Neurotransmitters Acetylcholin, einerseits Nikotin- und andererseits Muskarinrezeptoren sowie deren Subtypen entdeckt ...

Beyond dopamine blockade: mechanistic humility and the rise of muscarinic, TAAR1, and glutamatergic pathways in schizophrenia

Frontiers in Psychiatry
The approval of the first non–dopamine-blocking therapy for schizophrenia marks a defining moment in psychiatry. Muscarinic M1/M4 modulation, alongside emerging TAAR1 and glutamatergic pathways, signals a shift beyond dopamine dominance toward circuit ...

Asthma: From Phenotypes to Endotypes—Beyond Type 2 Inflammation

Respirology, EarlyView.
ABSTRACT Asthma is a heterogeneous syndrome featuring variable pathophysiology, clinical presentation and treatment response. This review examines a comprehensive endotype‐phenotype framework for asthma assessment with an emphasis on characteristics beyond T2 inflammatory status alone.

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 ...
