WebFilaggrin ( fil ament agg regating prote in) is a filament-associated protein that binds to keratin fibers in epithelial cells. Ten to twelve filaggrin units are post-translationally hydrolyzed from a large profilaggrin precursor protein during terminal differentiation of epidermal cells. [3] WebFilaggrin gene defects increase the risk of developing allergic sensitisation, atopic eczema and allergic rhinitis. Restoring skin barrier function early in life in individuals with filaggrin defects may help prevent the development of sensitisation and stop the development and progression of allergic disease.
