diffusion dynamics thus takes into account the proper diffusion
coeffi cients and the correct time scales of motion and signalling
(for molecules). Moreover, the chemokine concentration is
better characterised from a spatial point of view, leading to an
improved description of the chemotactic gradient felt by cells.
In C-ImmSim, it is possible to pick a time step in a range
between 120 and 480 minutes and cell diffusion processes
are automatically rescaled. Once the time step is selected, the
lattice unit is set equal to the distance that a T helper cell (i.e.,
the fastest cell entity in the model) can ...
