Cellular automata generalisation of the Weisbuch-Atlan model for immune response

Taking into account spatial fluctuations in the discrete model for certain types of immune response, the model of Weisbuch and Atlan (1988) is studied on a square lattice. In general, the authors end up with a healthy carrier state '29' where at all sites all cell types except activated killer cells are present. They study the time it takes to reach this fixed point, as well as effects of disorder and noise.
