Abstract X-rays can penetrate deeply into biological cells and thus allow for examination of their

Authors Rölleke U, Kumari P, Meyer R, Köster S Journal Current Opinion in Cell Biology Citation Curr Opin Cell Biol. 2023 Oct 21;85:102263. Abstract Together with actin filaments and microtubules, intermediate filaments (IFs) constitute the eukaryotic cytoskeleton and each of the three filament types contributes very distinct mechanical properties to

Authors Zelená A, Blumberg J, Probst D, Gerasimaitė R, Lukinavicius G, Schwarz US, Köster S Journal Biophysical Journal Citation Biophys J. 2023 Jul 19:S0006-3495(23)00461-7. Abstract Blood platelets are central elements of the blood clotting response after wounding. Upon vessel damage, they bind to the surrounding matrix and contract the forming

Authors Nageswaran S, Haipeter J, Bodenschatz JFE, Meyer R, Köster S, Steinem C Journal Biomacromolecules Citation Biomacromolecules. 2023 Jun 12;24(6):2512-2521. Abstract Within a cell, intermediate filaments interact with other cytoskeletal components, altogether providing the cell’s mechanical stability. However, little attention has been drawn to intermediate filaments close to the plasma

Authors Blob A, Ventzke D, Nies G, Dühmert JN, Schmitzer B, Munk A, Schaedel L, Köster S   Journal BioRxiv   Citation bioRxiv 2023.04.19.537509.   Abstract The eukaryotic cytoskeleton comprises three types of mechanically distinct biopoly-mers – actin filaments, microtubules and intermediate filaments (IFs)– along with pas-sive crosslinkers and active

Authors Kraxner J, Köster S Journal Biological Chemistry Citation Biol Chem. 2023 Apr 20. Abstract The cytoskeleton of eukaryotes consists of actin filaments, microtubules and intermediate filaments (IF). IFs, in particular, are prone to pronounced phosphorylation, leading to additional charges on the affected amino acids. In recent years, a variety

Authors Burchert JP, Graceffa R, Saldanha O, Burghammer M, Köster S Journal Journal of Synchrotron Radiation Citation J Synchrotron Radiat. 2023 May 1. Abstract Owing to their large penetration depth and high resolution, X-rays are ideally suited to study structures and structural changes within intact biological cells. For this reason,

Authors Steyer AM, Buscham TJ, Lorenz C, Hümmert S, Eichel-Vogel MA, Schadt LC, Edgar JM, Köster S, Möbius W, Nave KA, Werner HB Journal Glia Citation Glia. 2022 Nov 10. Abstract Healthy myelin sheaths consist of multiple compacted membrane layers closely encasing the underlying axon. The ultrastructure of CNS myelin

Authors Lorenz C, Köster S Journal Biophysics Reviews Citation Biophysics Rev. 3, 031304 (2022) Abstract Different types of biological cells respond differently to mechanical stresses, and these responses are mainly governed by the cytoskeleton. The main components of this biopolymer network are actin filaments, microtubules, and intermediate filaments, whose mechanical
