Bile acid metabolism and signaling in human and animal health: A One Health perspective

iMetaOmics, EarlyView.
Bile acids maintain host homeostasis through enterohepatic circulation, microbial transformation, and bile acid receptor signaling, thereby regulating glucose and lipid metabolism, intestinal barrier integrity, and immunity. These effects support human disease intervention and health‐oriented animal production, reducing drug dependence and residue ...

Oral Vitamin C Intake Ameliorates Crude Oil-Polluted Water-Induced Jejunal Contractile Dysfunctions in Wistar rats

Journal of Applied Sciences and Environmental Management, 2023
Inhabitants of rural Niger-Delta oil communities in Nigeria often, unintentionally, consume crude oil polluted water (COCW) due to crude oil spills in the region. The impact of vitamin C supplementation during COCW ingestion on the contractile mechanism

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 ...

Immunization with plasmids encoding M2 acetylcholine muscarinic receptor epitopes impairs cardiac function in mice and induces autophagy in the myocardium

Autoimmunity, 2018
Autoantibodies against the M2 subtype of muscarinic acetylcholine receptors with functional activities have been found in the sera of patients with dilated cardiomyopathy (DCM), and the second extracellular loop has been established as the predominant ...

AMPK‐mediated prevention of vascular dysfunction with metformin: Experimental and population‐based evidence

British Journal of Pharmacology, Volume 183, Issue 17, Page 5389-5406, September 2026.
Angiotensin II induces vascular inflammation, senescence, extracellular matrix (ECM) degradation and endothelial dysfunction, thus impairing SK+/IK+ channel function and reducing endothelial‐dependent hyperpolarisation (EDH). Metformin activates AMPK, increasing SK+/IK+ channel function and restoring vasorelaxation.
