Pushing off the walls: a mechanism of cell motility in confinement
R. J. Hawkins, M. Piel, G. Faure-Andre +4
We propose a novel mechanism of cell motility, which relies on the coupling of actin polymerization at the cell membrane to geometric confinement. We consider a polymerizing viscoe…
Mechanical response of active gels
T. B. Liverpool, M. C. Marchetti, J. -F. Joanny +1
We study a model of an active gel of cross-linked semiflexible filaments with additional active linkers such as myosin II clusters. We show that the coupling of the elasticity of t…
Membrane tension lowering induced by protein activity
M. D. El Alaoui Faris, D. Lacoste, J. Pecreaux +3
We present measurements of the fluctuation spectrum of giant vesicles containing bacteriorhodopsin (BR) pumps using video-microscopy. When the pumps are activated, we observe a sig…
Viscous Fingering-like Instability of Cell Fragments
A. C. Callan-Jones, J. -F. Joanny, J. Prost
We present a novel flow instability that can arise in thin films of cytoskeletal fluids if the friction with the substrate on which the film lies is sufficiently strong. We conside…
Generic theory of active polar gels: a paradigm for cytoskeletal dynamics
Karsten Kruse, Jean-Francois Joanny, Frank Julicher +2
We develop a general theory for active viscoelastic materials made of polar filaments. This theory is motivated by the dynamics of the cytoskeleton. The continuous consumption of a…
Fission of a multiphase membrane tube
Jean-Marc Allain, Cornelis Storm, Aurelien Roux +2
A common mechanism for intracellular transport is the use of controlled deformations of the membrane to create spherical or tubular buds. While the basic physical properties of hom…
