中文摘要：
心磷脂是构成线粒体内膜的特殊磷脂组分,是线粒体内膜不同功能态下的拓扑结构变化的主要参与者.本实验通过溶剂自然蒸发与微操注射两种途径,原位研究了溶液中电解质浓度改变程度对心磷脂构成的囊管结构稳定性的影响,以期对线粒体功能状态的变化机理有进一步的认识.实验发现,即使没有蛋白质对膜曲率的调制作用,单纯由溶液浓度改变造成的刺激也可以引起心磷脂膜组装形态的改变.皱缩的发生与膜表面的电势变化有关,是可受浓度调控的可逆过程.
英文摘要：
In order to understand the mechanism of the transition between different mitochondrial functional states, an in-situ study of the stability of myelin figure composed of cardiolipin was performed by changing the electrolyte concentration of systems. The methods of changing electrolyte concentration are the solvent-evaporation method and the micro-injection method. It was found that, even without protein regulation, the morphology of cardiolipin membrane could be reversibly mediated by only increasing or decreasing the electrolyte concentration. Moreover, the myelin crimple was related to the rising of zeta potential on the surface of membrane.
