A theory for coexistence and selection of branched actin networks in a shared and finite pool of monomers
Valentin Wössner, Falko Ziebert, Ulrich S. Schwarz
Cellular actin structures are continuously turned over while keeping similar sizes. Since they all compete for a shared pool of actin monomers, the question arises how they can coe…
Optogenetic switching of migration of contractile cells
Oliver M. Drozdowski, Falko Ziebert, Ulrich S. Schwarz
Cell crawling on flat substrates is based on intracellular flows of the actin cytoskeleton that are driven by both actin polymerization at the front and myosin contractility at the…
Optogenetic control of intracellular flows and cell migration: a comprehensive mathematical analysis with a minimal active gel model
Oliver M. Drozdowski, Falko Ziebert, Ulrich S. Schwarz
The actin cytoskeleton of cells is in continuous motion due to both polymerization of new filaments and their contraction by myosin II molecular motors. Through adhesion to the sub…
Stochastic Dynamics of Nanoparticle and Virus Uptake
Felix Frey, Falko Ziebert, Ulrich S. Schwarz
The cellular uptake of nanoparticles or viruses requires that the gain of adhesion energy overcomes the cost of plasma membrane bending. It is well known that this leads to a minim…
Dynamics of particle uptake at cell membranes
Felix Frey, Falko Ziebert, Ulrich S. Schwarz
Receptor-mediated endocytosis requires that the energy of adhesion overcomes the deformation energy of the plasma membrane. The resulting driving force is balanced by dissipative f…
