Switch from Systems Microbiology to Systems Cell Biology The importance of diffusion and gradients for cellular regulation
Switch from Systems Microbiology to Systems Cell Biology The importance of diffusion and gradients for cellular regulation 2
Part I: Systems Cell Biology Importance of gradients and diffusion In cellular regulation After two lectures on diffusion and reaction-diffusion equations We will focus during the coming lectures on the following biological systems 1. Eukaryotic chemotaxis Gradient sensing in Dictyostelium (aka' amoeba) 2. Computing the middle of a cell Pole-to-pole oscillations in Escherichia coll 3. Self organization of the cytoskeleton
