Abstract
In this work, a three-state cellular automaton proposed to describe part of a biological immune system is revisited. We obtain the dynamic critical exponent z of the model by means of a recent technique that mixes different initial conditions. Moreover, by using two distinct approaches, we have also calculated the global persistence exponent θg, related to the probability that the order parameter of the model does not change its sign up to time t [P(t)ât-θg].
