Equilibrium properties of a grafted polyelectrolyte with explicit counterions
K. Jayasree, P. Ranjith, Madan Rao +1
We study the equilibrium conformations of a grafted polyelectrolyte (PE) in the presence of explicit counterions (CI) using Monte Carlo simulations. The interplay between attractiv…
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…
Generic phase diagram of active polar films
R. Voituriez, J. F. Joanny, J. Prost
We study theoretically the phase diagram of compressible active polar gels such as the actin network of eukaryotic cells. Using generalized hydrodynamics equations, we perform a li…
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…
Mechanochemical action of the dynamin protein
Martin Lenz, Jacques Prost, Jean-François Joanny
Dynamin is a ubiquitous GTPase that tubulates lipid bilayers and is implicated in many membrane severing processes in eukaryotic cells. Setting the grounds for a better understandi…
