摘要
用数值模拟的方法研究了钙信号系统中钙振荡与IP3振荡共存时,噪音和低频外信号对它们的选择性优化和调控.研究结果显示,低频外信号能够协同噪音作用,在一定强度范围内优化钙信号和IP3信号,但能够协同优化钙信号的条件范围明显较宽,说明协同作用对钙信号具有优先选择性.此外,在两种化学信号均可以被优化的外信号参数作用下,信号被优化的噪音强度范围也具有选择性.
The selective optimization of calcium and IP3 signal by the ccoperation of external low frequency signal and noise is reported. Simulation results prove that when the two signals coexist in the system, the cooperation of external signal and noise can selectively optimize them in certain strength scope. The calcium signal is optimized in a wider range of cooperation condition than the IP3 signal, which shows the selectivity of the ccoperation. When both of the two signals can be optimized,the optimization is also selective in the range of noise intensity.
