Description

This Model describes how two coupled cells affect the oscillatory behavior of Ca2+ in each other. The model asumes that Ca2+ enters the cell either by mediation of IP3 receptor or as leaking, and Ca2+ solely leaves the cell by action of ATPase pumps. The simulation resembles the “same amplitude antiphase calcium oscillations of coupled cells” presented in figure 5b in the publication, using the specifications for the IP3R’s concentrations specified in BioModels Database due to no specifications for this species where given in the publication. Also, BioModels suggest that the time t=0 in the publication figure may have been fixed after the system settle, and therefore t=0 of the simulation in BioModels neither in Vcell correspond to the t=0 in the publication.
