This review explores thermosensation, focusing on TRPM3, TRPM4, and TRPM5 ion channels. These channels are crucial for detecting temperature, aiding survival across species.
Area of Science:
- Neuroscience
- Physiology
- Molecular Biology
Background:
- Temperature detection is vital for species survival.
- Thermoreceptors in the skin sense environmental and body temperatures.
- The discovery of TRPV1 led to identifying 11 thermo-sensitive TRP channels.
Purpose of the Study:
- To review the expression patterns of TRPM3, TRPM4, and TRPM5.
- To summarize the electrophysiological properties of these TRP channels.
- To elucidate the physiological roles of TRPM3, TRPM4, and TRPM5 in thermosensation.
Main Methods:
- Literature review of scientific publications.
- Analysis of expression patterns in sensory neurons.
- Examination of electrophysiological data and functional studies.
Main Results:
- TRPM3 acts as a sensor for noxious heat in sensory neurons.
- TRPM4 and TRPM5 are calcium-activated cation channels potentiated by temperature.
- These channels exhibit distinct expression profiles and functional roles in thermosensation.
Conclusions:
- TRPM3, TRPM4, and TRPM5 are key players in thermosensation.
- Understanding these channels deepens our knowledge of temperature perception.
- Further research can explore therapeutic applications targeting these TRP channels.

Enzyme-linked Receptors
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

Voltage-gated Ion Channels
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...
