Area of Science:

  • Dermatology and Cell Biology
  • Investigating the molecular mechanisms of skin barrier function.

Background:

  • Tight junctions (TJ) are established as critical for barrier formation and cell polarity in simple epithelia and endothelia.
  • Their role in amphibian skin barrier function is well-documented.
  • Recent identification of TJ and TJ proteins in mammalian epidermis marks a significant advancement.

Purpose of the Study:

  • To review the current understanding of tight junctions (TJ) and TJ proteins in mammalian skin.
  • To consolidate recent findings on the involvement of TJ in mammalian skin barrier function.

Main Methods:

  • This is a review article, synthesizing existing research.
  • Literature search and critical analysis of studies on TJ in mammalian skin.

Main Results:

  • Tight junctions and their associated proteins have been identified in the epidermis of humans and mice.
  • Evidence supports the crucial role of these TJ proteins in maintaining the barrier integrity of mammalian skin.

Conclusions:

  • Tight junctions are essential components of the mammalian skin barrier.
  • Further research into TJ proteins will enhance our understanding of skin physiology and disease.
