The keratin cortex stabilizes cells at high strains

Authors Meyer R, Rölleke U, Schwarz N, Perez-Tirado A, Schepers AV, Janshoff A, Köster S Journal BioRxiv Citation bioRxiv 2025.02.24.639846. Abstract The eukaryotic cytoskeleton consists of three filament types: actin filaments, microtubules and intermediate filaments (IFs). IF proteins are expressed in a cell-type specific manner, and keratins are found in
