Insights

Epidermal growth factor receptor (EGFR) signaling is crucial for skin health. New research shows the calcium channel TRPV3 is essential for these EGFR-dependent skin functions.

Area of Science:

  • Dermatology
  • Cell Biology
  • Molecular Biology

Background:

  • Epidermal growth factor receptor (EGFR) signaling plays a vital role in skin development and maintenance.
  • Key functions include keratinocyte differentiation, hair follicle development, and skin barrier integrity.

Discussion:

  • Cheng et al. demonstrate that the transient receptor potential vanilloid 3 (TRPV3) channel is indispensable for EGFR-dependent processes.
  • This highlights a critical link between calcium signaling and EGFR pathways in skin biology.

Key Insights:

  • TRPV3 is required for EGFR-mediated keratinocyte terminal differentiation.
  • TRPV3 is essential for normal hair morphogenesis.
  • The calcium channel TRPV3 is necessary for maintaining the skin barrier function, dependent on EGFR signaling.

Outlook:

  • Further investigation into the TRPV3-EGFR interaction could reveal new therapeutic targets for skin disorders.
  • Understanding this crosstalk may lead to novel treatments for conditions involving impaired skin barrier or hair growth.

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...

Resting Membrane Potential01:24

Resting Membrane Potential

The relative difference in electrical charge, or voltage, between the inside and the outside of a cell membrane, is called the membrane potential. It is generated by differences in permeability of the membrane to various ions and the concentrations of these ions across the membrane.
The Inside of a Neuron is More Negative
The membrane potential of a cell can be measured by inserting a microelectrode into a cell and comparing the charge to a reference electrode in the extracellular fluid. The...

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...
