Role of Muscarinic Acetylcholine Signaling in Gastrointestinal Cancers

Biomedicines, 2019
In the tumor microenvironment, various stromal and immune cells accumulate and interact with cancer cells to contribute to tumor progression. Among stromal players, nerves have recently been recognized as key regulators of tumor growth.

Multiple Residues in the Second Extracellular Loop Are Critical for M3 Muscarinic Acetylcholine Receptor Activation [PDF]

, 2007
Recent studies suggest that the second extracellular loop (o2 loop) of bovine rhodopsin and other class I G protein-coupled receptors (GPCRs) targeted by biogenic amine ligands folds deeply into the transmembrane receptor core where the binding of cis ...

Effect of the Arg16Gly β2‐Adrenergic Receptor Polymorphism on Long‐Term Mepolizumab Response and Clinical Remission in Severe Eosinophilic Asthma: A Genotype‐Stratified, Multicenter Study

Allergy, EarlyView.
This study examines the association between the rs1042713 (Arg16Gly) polymorphism of the β2‐adrenergic receptor and the risk of severe eosinophilic asthma, as well as its influence on mepolizumab long‐term effectiveness and clinical remission. The Arg16 allele is associated with increased risk of severe disease and potentially diminished long‐term ...

Relationship between membrane phosphatidylinositol-4,5-bisphosphate and receptor-mediated inhibition of native neuronal M channels [PDF]

, 2005
The relationship between receptor-induced membrane phosphatidylinositol-4'5'-bisphosphate (PIP2) hydrolysis and M-current inhibition was assessed in single-dissociated rat sympathetic neurons by simultaneous or parallel recording of membrane current and ...

Vasoreactivity as a Measure of Kidney Viability During Ex Vivo Normothermic Machine Perfusion

Artificial Organs, EarlyView.
This study aimed to investigate the influence of warm ischemic injury on renal vascular responsiveness to vasoactive drugs during normothermic machine perfusion (NMP). We found that the vascular responses to dopamine and norepinephrine could be used as objective indicators to assess kidney viability during NMP.

Presynaptic M1 muscarinic cholinoceptors mediate inhibition of excitatory synaptic transmission in the hippocampus in vitro [PDF]

, 1990
The effects of the cholinoceptor agonist, carbachol (CCh), were examined in the rat hippocampal slice preparation. Intracellular recordings from CA1 pyramidal neurones revealed that CCh (1–3 μM) inhibited excitatory postsynaptic responses evoked by ...

Evaluation of preclinical antipsychotic models used to support first‐in‐human clinical trials

British Journal of Pharmacology, EarlyView.
Abstract Schizophrenia is regarded as a complex and heterogeneous psychiatric disorder, characterised by diverse symptoms and comorbidities, which complicate both clinical management and drug development. Current pharmacological treatment, primarily based on dopamine D2 receptor antagonism or partial agonism, which has not markedly progressed since the

Basic and Clinical Aspects of Non-neuronal Acetylcholine: Overview of Non-neuronal Cholinergic Systems and Their Biological

Journal of Pharmacological Sciences, 2008
Acetylcholine (ACh) is a phylogenetically ancient molecule involved in cell-to-cell signaling in almost all life-forms on earth. Cholinergic components, including ACh, choline acetyltransferase, acetylcholinesterase, and muscarinic and nicotinic ACh ...
