Recent data have provided important clues about the molecular mechanisms underlying certain neurodegenerative diseases. Most cell death in vertebrates proceeds via the mitochondrial pathway of apoptosis. Mitochondria contain proapoptotic factors such as cytochrome c and AIF in their intermembrane space. Furthermore, mitochondrial membrane permeabilization (MMP) is a critical event during apoptosis, representing the "point of no return" of the lethal process. Modern medicine is developing an increasing number of drugs for neurodegenerative disease, but no neuroprotective treatment has yet been established. While current treatments temporarily alleviate symptoms, they do not halt disease progression. This paper briefly reviews the pharmacological inhibition of mitochondrial membrane permeabilization for neuroprotection.
近期的数据为某些神经退行性疾病背后的分子机制提供了重要线索。脊椎动物中的大多数细胞死亡是通过凋亡的线粒体途径进行的。线粒体在其膜间隙中含有细胞色素c和凋亡诱导因子等促凋亡因子。此外,线粒体膜通透性改变(MMP)是凋亡过程中的一个关键事件,代表着致死过程的“不可逆点”。现代医学正在研发越来越多针对神经退行性疾病的药物,但尚未确立神经保护治疗方法。虽然目前的治疗方法能暂时缓解症状,但并不能阻止疾病进展。本文简要综述了用于神经保护的线粒体膜通透性改变的药理学抑制作用。
