摘要：

We study the spreading of calcium-induced calcium release with the stochastic DeYoung-Keizer-model of the inositol 1,4,5-trisphosphate receptor channel. The model shows a transition from isolated release events to steadily propagating waves with increasing IP3 concentration. A state-stochastic backfiring-was found in the regime of steady propagation. The model can be reduced by an adiabatic elimination of the partial differential equation for the Ca2+ concentration to a lattice of stochastic channel clusters.
