Background:

  • The cornified cell envelope (CE) forms inside the plasma membrane of terminally differentiated keratinocytes.
  • It is a crucial, highly insoluble structure contributing to the epidermal barrier function.

Purpose of the Study:

  • To outline the cellular and molecular biology of the cornified cell envelope.
  • To review emerging research areas concerning the CE.

Main Methods:

  • Review of existing literature on CE morphology and biochemistry.
  • Analysis of sequential gene expression during keratinocyte differentiation.
  • Investigation of lipid-protein interactions in epidermal barrier formation.

Main Results:
