钙交替与T波交替和脉搏交替有关,这是心脏病死亡率增加的先兆。最近的实验、计算和理论研究使人们对钙交替的机制有了新的认识,特别是如何在亚细胞水平上将由随机过程主导的无序行为组织成有序的周期行为。在本文中,我们总结了这一领域的最新进展,概述了一个整体的理论框架,其中钙循环蛋白对钙交替的复杂影响与心脏钙循环网络的三个关键特性有关:随机性、不应性和募集。我们还说明了这个“3R理论”如何能够调和许多看似矛盾的实验观察。
Calcium alternans is associated with T-wave alternans and pulsus alternans, harbingers of increased mortality in the setting of heart disease. Recent experimental, computational, and theoretical studies have led to new insights into the mechanisms of Ca alternans, specifically how disordered behaviors dominated by stochastic processes at the subcellular level become organized into ordered periodic behaviors. In this article, we summarize the recent progress in this area, outlining a holistic theoretical framework in which the complex effects of Ca cycling proteins on Ca alternans are linked to three key properties of the cardiac Ca cycling network: randomness, refractoriness, and recruitment. We also illustrate how this ‘3R theory’ can reconcile many seemingly contradictory experimental observations.
