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 cytoskeletonPart II: Systems Cell Biology ‘Importance of gradients and diffusion in cellular regulation’ 3 After two lectures on diffusion and reaction-diffusion equations, we will focus during the coming lectures on the following biological systems: 1.
