Intercellular Skin Barrier Lipid Composition and Organization in Netherton Syndrome Patients
Netherton Syndrome (NTS) is a rare genetic skin disease caused by mutations in the serine protease inhibitor Kazal-type 5 gene, which encodes the lympho-epithelial Kazal-type-related inhibitor. NTS patients have a profound impaired skin barrier function. Because SC lipids play a crucial role in the…
