Active behavior of the cytoskeleton

Many movements of eukaryotic cells are driven by the cytoskeleton. This cellular structure plays essential roles in various vital processes like cell division, cell locomotion, or the internal organization of subcellular components. It consists of filamentous proteins, notably microtubules and actin filaments, which interact with a host of proteins affecting filament lengths, acting as cross-linkers, or functioning as molecular motors. In living cells, the cytoskeleton is maintained out of thermodynamic equilibrium by the hydrolysis of ATP, which drives, for example, the assembly and disassembly of filaments or the action of motors. These processes lead to the generation of internal stresses and spontaneous flows. In this talk, a hydrodynamic description of cytoskeletal dynamics will be presented. This description is based on symmetries only and applies whenever the systems is sufficiently close to thermodynamic equilibrium. As a first example, it will be applied to the dynamics of active polar films. Finally, selected cellular structures will be discussed in light of the theory.
