title: [Dysfunction of mitochondrial dynamic and distribution in Amyotrophic Lateral Sclerosis].
abstract: Amyotrophic lateral sclerosis (ALS) is a complex disease leading to degradation of motor neurons. One of the early symptoms of many neurodegenerative disorders are mitochondrial dysfunctions. Since few decades mitochondrial morphology changes have been observed in tissues of patients with ALS. Mitochondria are highly dynamic organelles which constantly undergo continuous process of fusion and fission and are actively transported within the cell. Proper functioning of mitochondrial dynamics and distribution is crucial for cell survival, especially neuronal cells that have long axons. This article summarizes the current knowledge about the role of mitochondrial dynamics and distribution in pathophysiology of familial and sporadic form of ALS.
