Thermosensation01:43

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...
Mechanically-gated Ion Channels01:12

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...

Voltage-gated Ion Channels01:26

Voltage-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...

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.

Background:

  • Transient Receptor Potential Vanilloid sub type 4 (TRPV4) channels are crucial for sensing stimuli and physiological functions.
  • TRPV4 gene mutations are linked to several genetic disorders, including Brachyolmia and Charcot-Marie-Tooth disease type 2C.

Purpose of the Study:

  • To review how TRPV4 mutations affect cellular and molecular functions.
  • To explore the role of cellular factors in modulating TRPV4 channel activity and disease pathogenesis.

Main Methods:

  • Analysis of naturally occurring and engineered TRPV4 mutants.
  • Examination of cellular processes including oligomerization, trafficking, and degradation.
  • Investigation of signaling events and functional interactions.

Main Results:

  • Altered channel activity alone does not fully explain TRPV4-related disorders.
  • Other factors modulate TRPV4 oligomerization, trafficking, and degradation.
  • These factors can enhance or reduce TRPV4 channel activity, contributing to disease.

Conclusions:

  • Cellular and molecular mechanisms beyond direct channel function are critical in TRPV4-related genetic disorders.
  • Understanding these interactions is key to developing therapeutic strategies for conditions linked to TRPV4 mutations.
