The research for this thesis was carried out at the Netherlands Institute for Neuroscience, an Institute of the Royal Academy of Arts and Sciences (KNAW), Amsterdam, The Netherlands and at FOM institute for Atomic and Molecular Physics (AMOLF), an Institute of the Foundation for Fundamental Research on Matter (FOM). About the cover: The most remarkable characteristic of intermediate filaments is their beautiful structure of ca. 10 nm thick filaments in aligned bundles. One of the intermediate filaments proteins got its name from this structure, as stated in the 1978 paper by Werner Franke: Vimentin: From the Latin word vimentum, used to describe arrays of flexible rods, both ordered ones (e.g., lattices, filigrees, and wicker-work) and nonordered ones (e.g., brushwood). But as is described in this thesis, there s more to intermediate filaments than that structure, we have to look beyond the wicker-work. Cover Design: Heleen Bijkerk Layout: Oscar Stassen The work described in this thesis is part of the research programme of the Foundation for Fundamental Research on Matter (FOM), which is part of the Netherlands Organisation for Scientific Research (NWO).
