Molecular motors enhance microtubule lattice plasticity
William Lecompte, Karin John
Microtubules are key structural elements of living cells that are crucial for cell division, intracellular transport and motility. Recent experiments have shown that microtubule se…
Spontaneous polarization in an interfacial growth model for actin filament networks with a rigorous mechano-chemical coupling
Karin John, Denis Caillerie, Chaouqi Misbah
Many processes in eukaryotic cells, including cell motility, rely on the growth of branched actin networks from surfaces. Despite its central role the mechano-chemical coupling mec…
A constitutive law for cross-linked actin networks by homogenization techniques
Denis Caillerie, Karin John, Chaouqi Misbah +2
Inspired by experiments on the actin driven propulsion of micrometer sized beads we develop and study a minimal mechanical model of a two-dimensional network of stiff elastic filam…
Transport of free surface liquid films and drops by external ratchets and self-ratcheting mechanisms
Uwe Thiele, Karin John
We discuss the usage of ratchet mechanisms to transport a continuous phase in several micro-fluidic settings. In particular, we study the transport of a dielectric liquid in a hete…
Actin based propulsion: Intriguing interplay between material properties and growth processes
Karin John, Denis Caillerie, Philippe Peyla +3
Eukaryotic cells and intracellular pathogens such as bacteria or viruses utilize the actin polymerization machinery to propel themselves forward. Thereby, the onset of motion and c…
Self-ratcheting Stokes drops driven by oblique vibrations
Karin John, Uwe Thiele
We develop and analyze a minimal hydrodynamic model in the overdamped limit to understand why a drop climbs a smooth homogeneous incline that is harmonically vibrated at an angle d…
