Microscopic origin of macroscopic contractility in actin-myosin active gel models
Artur Alexandre, Nicola Dietler, Simone Cicolini +3
Actin filaments, crosslinkers and myosin molecular motors form contractile networks. For instance, the cell cortex is a thin network below the cell membrane ; contraction of the ce…

Force-Velocity Relationship in Branched Actin Networks: Consequences of Entanglement, Drag and Stall Force
Magid Badaoui, Serge Dmitrieff
We investigate the growth of a branched actin network under load. Using a combination of simulations and theory, we show that the network adapts to the load and exhibits two regime…

Rotation-Beating dynamics of a driven flexible filament: role of motor protein properties
Amir Khosravanizadeh, Serge Dmitrieff
We have used numerical simulations to investigate how the properties of motor proteins control the dynamical behavior of a driven flexible filament. The filament is pinned at one e…
