Skin and Cellular Biology Research

Keratins, vimentin, desmin, and neurofilaments belong to a family of structural proteins called intermediate filaments, which form the mechanical scaffolding inside cells and are particularly critical in tissues like skin that face constant physical stress. When mutations disrupt these proteins or the genes regulating them, the consequences can be severe: in epidermolysis bullosa, for instance, defective keratins cause skin to blister under minimal friction, while mutations in serine protease inhibitors underlie conditions like Netherton syndrome, where the skin barrier breaks down entirely. Researchers are working to understand precisely how specific mutations alter filament assembly and cell mechanics, and how intermediate filament networks interact with adhesion complexes to coordinate processes like wound healing and cell migration. A central open question is how cells regulate filament composition dynamically across different tissues and disease states, which could point toward targeted therapies for inherited skin disorders that currently have no cure.
