利用简单的模式生物如果蝇、酵母和C.优雅的除了线粒体分裂和融合在控制细胞器形状,大小和数量方面的主要功能外,很明显,这些动态过程对于调节细胞死亡,线粒体自噬和细胞器分布也至关重要。现在,研究表明,在广泛的神经退行性疾病中,线粒体动力学发生了显著的变化,并且有大量证据表明在疾病发病机制中起着关键作用,因为神经元是最耗能的细胞类型之一,并且具有高度发达的细胞形状。在这里,我们回顾了最近的研究结果在神经退行性病变的线粒体动力学。
It has been only 15 years since studies began on the molecular mechanisms underlying mitochondrial fission and fusion using simple model organisms such as Drosophila, yeast, and C. elegans. Beyond the primary functions of mitochondrial fission and fusion in controlling organelle shape, size and number, it became clear that these dynamic processes are also critical for regulating cell death, mitophagy and organelle distribution. Now, studies suggest that prominent changes occur in mitochondrial dynamics in a broad array of neurodegenerative disease, and there is substantial evidence suggesting a key role in disease pathogenesis, as neurons are among the most energy-consuming cell types and have a highly developed cell shape. Here, we review the recent findings on mitochondrial dynamics in neurodegeneration.
