Summary
Ion channel dysfunction causes salivary gland hypofunction and xerostomia. Targeted therapies, including gene therapy, show promise for restoring salivary gland function and treating dry mouth.
Area of Science:
- Physiology
- Pathology
- Pharmacology
Background:
- Salivary gland hypofunction and xerostomia are common side effects of radiation therapy, Sjögren's disease, and inherited disorders.
- Ion channel dysfunction is a key mechanism underlying salivary gland diseases.
Purpose of the Study:
- To review current knowledge on ion channel dysfunction in salivary gland pathology.
- To evaluate ion channel-targeted therapeutic strategies for salivary gland disorders.
Main Methods:
- A comprehensive narrative review of studies was conducted.
- Databases searched include PubMed, Scopus, and Web of Science.
- Studies focused on ion channel regulation in salivary gland physiology and disease.
Main Results:
- Salivary secretion relies on calcium signaling and ion transport in acinar and ductal cells.
- Disruptions in calcium, chloride, and water channels impair fluid secretion in various conditions.
- Targeted therapies like muscarinic agonists, ANO1/CFTR modulators, and gene therapy show potential.
Conclusions:
- Ion channels are crucial for salivary gland function and represent viable therapeutic targets.
- Combining pharmacologic, gene, and regenerative medicine offers a precise approach to restore salivary function.
- Restoring salivary gland function can alleviate symptoms like dry mouth.

01:19Ligand-gated Ion Channels
Ligand-gated ion channels are transmembrane proteins with a channel for ions to pass through and a binding site for a ligand. The channel opens only when a ligand attaches to the binding site.
Three Subfamilies of Ligand-gated Ion Channels
Ligand-gated ion channels fall into three subfamilies. The 'Cys-loop' includes the nicotinic acetylcholine receptors, γ-aminobutyric acid (GABA), glycine, and 5-hydroxytryptamine receptors. The second one is the 'Pore-loop' channels that include the...

01:23Salivary Glands and Saliva
The salivary glands, of which there are three pairs known as the parotid, submandibular, and sublingual glands, play a crucial role in maintaining oral health and initiating the digestive process. Positioned near the ears, beneath the masseter muscle, the parotid glands secrete saliva into the oral cavity through the parotid duct of Stensen. Meanwhile, the submandibular glands, located on the floor of the mouth, secrete saliva through channels named submandibular ducts. The sublingual glands,...
01:30Ligand-Gated Ion Channel Receptor: Gating Mechanism
Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...
01:11Direct-Acting Cholinergic Agonists: Therapeutic Uses
Direct-acting cholinergic agonists have many therapeutic uses in various medical fields. Choline esters, including acetylcholine, have limited clinical utility due to their non-selectivity and short duration of action. Still, acetylcholine and carbachol are applied topically during ophthalmologic surgery to induce miosis. Pilocarpine, a muscarinic and ganglionic stimulator, effectively treats open-angle glaucoma and alleviates xerostomia and dry mouth caused by radiotherapy or Sjögren syndrome.
01:26Voltage-gated Ion Channels
Voltage-gated ion channels are transmembrane proteins that open and close in response to changes in the membrane potential. They are present on the membranes of all electrically excitable cells such as neurons, heart, and muscle cells.
Generally, all voltage-gated ion channels have a 'voltage-sensing domain' that spans the lipid bilayer. The charged residues in the sensor move in response to the membrane potential changes that open the channel allowing ions movement. There are several types of...

01:12Mechanically-gated Ion Channels
Mechanically-gated ion channels are proteins found in eukaryotic and prokaryotic cell membranes that open in response to mechanical stress. Tension, compression, swelling, and shear stress can alter the conformation of the protein, opening a transmembrane channel that allows the passage of ions for signal transmission. In eukaryotes, mechanically-gated channels are distributed in several regions like the neurons, lungs, skin, bladder, and heart, where they play critical roles in numerous...
