Activation of Muscarinic Acetylcholine Receptor Subtype 4 is Essential for Cholinergic Stimulation of Gastric Acid Secretion - Relation To D Cell/Somatostatin -

Frontiers in Pharmacology, 2016
Background/Aim: Muscarinic acetylcholine receptors exist in five subtypes (M1~M5), and they are widely expressed in various tissues to mediate diverse autonomic functions, including gastric secretion.

Whole‐Genome Sequencing and Resequencing of Hucho bleekeri Provides Insights into Genetic Mechanisms of Environmental Adaptation

Integrative Zoology, EarlyView.
A high‐quality chromosome‐level reference genome was constructed for Hucho bleekeri. Population structure and environmental adaptation of Hucho species were revealed by whole‐genome resequencing. ABSTRACT Salmonidae represents an important family in the study of genome evolution following genome duplication.

Dualsteric and dual‐acting modulation of muscarinic receptors by antagonist KH‐5

British Journal of Pharmacology, EarlyView.
Abstract Background and purpose Muscarinic acetylcholine receptors are key therapeutic targets, and ligands engaging both orthosteric and allosteric sites may offer improved selectivity and efficacy. Here, we investigated whether the muscarinic antagonist KH‐5 acts as a dualsteric antagonist and defined its mode of interaction with muscarinic receptors.

Muscarinic agonists for schizophrenia: Bridging preclinical evidence and clinical enthusiasm

British Journal of Pharmacology, EarlyView.
Abstract Antipsychotic drugs targeting dopamine receptors have been used to treat schizophrenia for decades, primarily alleviating positive symptoms such as hallucinations and delusions. However, they provide limited benefit for cognitive and negative symptoms—major contributors to poor outcomes—and are frequently associated with significant side ...

Physiological functions of the cholinergic system in immune cells

Journal of Pharmacological Sciences, 2017
T and B cells, macrophages and dendritic cells (DCs) all express most of the components necessary for a functional cholinergic system. This includes choline acetyltransferase (ChAT), muscarinic and nicotinic acetylcholine (ACh) receptors (mAChRs and ...

Ion Channel Dysfunction and Therapeutic Targeting in Salivary Gland Disorders

Oral Diseases, EarlyView.
ABSTRACT Objective Salivary gland hypofunction and xerostomia represent major clinical complications of radiation therapy, autoimmune disorders such as Sjögren's disease, and inherited epithelial ion transport defects. This review integrates current knowledge on ion channel dysfunction as a central mechanistic driver of salivary gland pathology and ...

Chotosan, a Kampo Formula, Ameliorates Chronic Cerebral Hypoperfusion-Induced Deficits in Object Recognition Behaviors and Central Cholinergic Systems in Mice

Journal of Pharmacological Sciences, 2007
We previously demonstrated that the Kampo formula chotosan (CTS) ameliorated spatial cognitive impairment via central cholinergic systems in a chronic cerebral hypoperfusion (P2VO) mouse model.
