The TRPM8 channel as a potential therapeutic target for bladder hypersensitive disorders
1Department of Pharmacology and Toxicology, Dokkyo Medical University, 880 Kitakobayashi, Mibu, Tochigi 321-0293, Japan.
Summary
Transient Receptor Potential Melastatin 8 (TRPM8) channels in the bladder are key sensors. Blocking TRPM8 may treat bladder hypersensitivity disorders like overactive bladder.
Area of Science:
- Urology
- Neuroscience
- Pharmacology
Background:
- Transient Receptor Potential (TRP) channels are crucial sensors in the lower urinary tract.
- TRP Melastatin 8 (TRPM8) channels are expressed in bladder-innervating neurons, responding to cold and chemical stimuli.
- TRPM8 channels are implicated in bladder sensory function and hypersensitivity.
Purpose of the Study:
- To review the functional role of TRPM8 channels in the lower urinary tract.
- To explore the therapeutic potential of TRPM8 antagonists for bladder disorders.
Main Methods:
- Literature review of studies on TRPM8 channel function in the lower urinary tract.
- Analysis of pharmacological investigations in rodents and humans regarding TRPM8 and bladder hypersensitivity.
Main Results:
- TRPM8 channels significantly contribute to bladder afferent sensory function.
- Evidence suggests TRPM8 channels play a role in the pathophysiology of bladder hypersensitivity.
- Rodent and human studies support TRPM8's involvement in bladder afferent hypersensitivity.
Conclusions:
- TRPM8 channels are vital for bladder sensory perception.
- TRPM8 antagonists represent a promising therapeutic strategy for bladder hypersensitive disorders.
- Targeting TRPM8 could alleviate symptoms such as urinary urgency and pain.

Thermosensation
32.0K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

Mechanically-gated Ion Channels
6.8K
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...

The Micturition Reflex
1.2K
Urination, or micturition involves the coordination of the bladder's detrusor muscle and two sphincters to ensure controlled bladder emptying.
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating...

Ligand-gated Ion Channels
12.8K
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...

Ligand-Gated Ion Channel Receptor: Gating Mechanism
2.8K
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...
