Abstract
Caffeine-derived microplasmodia possess a Ca++-sequestering system which can initiate motility. The experiments presented here suggest that this system is membranous and nonmitochondrial in nature. Therefore, it is proposed that the shuttle streaming in the plasmodium is controlled by the localized release and uptake of free Ca++ from an intracellular storage system analogous to the sarcoplasmic reticulum.
摘要
咖啡因来源的微原质团拥有一个能引发运动的钙离子隔离系统。此处呈现的实验表明，该系统本质上是膜性且非线粒体的。因此，有人提出，原质团中的穿梭流动是由类似于肌浆网的细胞内储存系统中游离钙离子的局部释放和摄取所控制的。
