The Phospholipases A of Epidermis
Journal of Investigative Dermatology, 1980 Phospholipases A have been characterized in fetal rat epidermis. Both a calcium dependent phospholipase A with pH optimum of 8.5 and a calcium independent enzyme with a pH optimum of 4.5 were found. Activity against both acyl groups of phosphatidyl choline were found for both enzymes and the findings suggested that the acid enzyme (pH 4.5) is primarily

The plant hormone ethylene restricts Arabidopsis growth via the epidermis
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance Ethylene is a gaseous hormone that controls plant life throughout development. Being a simple hydrophobic molecule, it can freely enter cells; therefore, the cell type specificity of its action is challenging.

A tension-adhesion feedback loop in plant epidermis
eLife, 2018 Mechanical forces have emerged as coordinating signals for most cell functions. Yet, because forces are invisible, mapping tensile stress patterns in tissues remains a major challenge in all kingdoms. Here we take advantage of the adhesion defects in the

Langerhans Cells—Programmed by the Epidermis
Frontiers in Immunology, 2017 Langerhans cells (LCs) reside in the epidermis as a dense network of immune system sentinels. These cells determine the appropriate adaptive immune response (inflammation or tolerance) by interpreting the microenvironmental context in which they ...

Type XVII collagen coordinates proliferation in the interfollicular epidermis
eLife, 2017 Type XVII collagen (COL17) is a transmembrane protein located at the epidermal basement membrane zone. COL17 deficiency results in premature hair aging phenotypes and in junctional epidermolysis bullosa.
