We investigate the role of Intermediate filaments, especially vimentin, on biophysical properties of cells, such as cell migration, stiffness and polarity. We are further interested in the interplay of vimentin with actin and microtubules. Finally, we are investiagting the structure and dynamics of the actin cortex and microtentacles in suspended cells.
High resolution microscopy techniques (Confocal, SEM),
Laser manipulation techniques: Fluorescent Recovery After Photobleaching (FRAP), Laser Ablation
Migration assays of both strongly and weakly adherent cells (e.g. microchambers for immune cell migration)
Cell mechanical properties for both adherent and non adherent cells
specific drugs targeting IFs
