    Glossary Lymphoepithelial Kazal-type-related Inhibitor

    protein regulating skin and hair enzyme activity

    Lymphoepithelial Kazal-type-related Inhibitor (LEKTI) is a protein that plays a crucial role in regulating the activity of certain enzymes involved in skin and hair health. It acts as a serine protease inhibitor, helping to maintain the integrity of the skin barrier and prevent excessive inflammation. Mutations in the gene encoding LEKTI can lead to skin disorders such as Netherton syndrome, which is characterized by red, scaly skin and hair abnormalities.
