Transport on inhomogeneous filament networks — •Philip Greulich and Ludger Santen — Fachrichtung Theoretische Physik, Universität des Saarlandes, 66041 Saarbrücken, Germany

We present a model for intracellular vesicle transport on submembranal actin networks. These networks are created by stochastic growth dynamics of actin filaments leading to an inhomogeneous structure. The dynamics of vesicles are implemented by an interplay of active transport on filaments and diffusion in the cytosol, while steric interactions of vesicles are taken into account. One observes the formation of vesicle clusters in a wide range of parameter space. We investigate the distribution of cluster sizes and compare these results to a system without filaments but attractive interactions between vesicles.
