Insights

Transient receptor potential (TRP) channels transport various metal ions beyond calcium and sodium. This review explores the intricate interplay between these TRP channels and metal ions, revealing new biological roles.

Area of Science:

  • Biochemistry
  • Cell Biology
  • Physiology

Background:

  • Transient receptor potential (TRP) channels are a large family of mammalian cation channels.
  • TRP channels are primarily known for transporting calcium and sodium ions at the plasma membrane.
  • Their roles in various biological processes are well-established.

Purpose of the Study:

  • To review the complex relationship between metal ions and TRP channels.
  • To highlight the emerging roles of TRP channels in transporting biologically relevant metal ions.
  • To discuss the regulatory effects of metal ions on TRP channel activity and expression.

Main Methods:

  • Literature review of recent studies on TRP channels and metal ions.
  • Analysis of research on TRP channel function and metal ion transport.
  • Synthesis of findings on metal ion regulation of TRP channel activity.

Main Results:

  • TRP channels transport metal ions such as zinc, magnesium, manganese, and cobalt.
  • Metal ions like magnesium, gadolinium, lanthanum, and cisplatin can regulate TRP channel activity and expression.
  • This expands the known functions of TRP channels beyond simple cation transport.

Conclusions:

  • TRP channels exhibit a broader ion transport capability than previously understood.
  • Metal ions play a significant role in modulating TRP channel function.
  • Further research is warranted to fully elucidate these complex interactions and their physiological implications.

Mechanically-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...

Ion Channels

The movement of ions like sodium, potassium, and calcium into and out of the cell is essential to maintain the electrochemical gradient in living cells. The ion channels—a class of membrane transport proteins—help maintain this ionic gradient for the smooth functioning of physiological activities such as maintaining cell size and volume, conducting nerve impulses, and gas and nutrient exchange.

Non-gated Ion Channels01:24

Non-gated Ion Channels

Ion channels are specialized proteins on the plasma membrane that allow charged ions to pass down their electrochemical gradient. Their main function is to maintain the membrane potential which is critical for cell viability. These channels are either gated or non-gated and can transport more than a thousand ions within milliseconds for the cellular event to occur.
Compared to the gated ion channels, the non-gated channels, also known as leakage or passive channels, have no gating mechanism....

Thermosensation

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...
