The importance of muscarinic receptors in domestic animal diseases and therapy: Current and future perspectives.

This research article reviews and discusses the role and importance of muscarinic acetylcholine receptors (mAChRs) in the health and diseases of domestic animals. It details how mAChRs function in different organ systems, their overall contribution to the well-being of these animals, and their potential as targets for medical therapy.

Muscarinic Acetylcholine Receptors (mAChRs) Overview

• The article begins by introducing muscarinic acetylcholine receptors, which are part of the G protein-coupled receptor family. They regulate central and peripheral nervous system functions, influencing all major body functions in animals.
• Though these receptors have been studied for decades, it’s noted that there are still just a few dedicated studies on mAChRs in domestic animal tissues.

mAChR System Pharmacology

• The researchers focus on the pharmacology of the mAChR system, detailing its role in the pathology and therapeutic treatments in organ systems of domestic animals.
• They discuss the biochemistry, function, and distribution of these receptors, along with recent advances in the field.

mAChRs in Different Body Systems

• The study dives into the involvement of mAChRs in various systems, including cardiovascular, respiratory, neurological, gastrointestinal (GI), and urological diseases, as well as in anaesthesia and toxicology.
• Through each system, specific functions of mAChRs are described in detail, including subtype characterization, smooth muscle functions, signal transduction, and regulation.

Therapeutic Promise of mAChRs

• Finally, the authors highlight the potential of mAChRs as therapeutic targets for treating animal diseases. This conclusion is based on their wide tissue distribution in the body.
• Specific diseases that could potentially be treated by targeting mAChRs include equine recurrent airway obstruction, glaucoma, abnormalities of gastric acid secretion, and gastrointestinal disturbances like colic.
