Mitochondrial respiratory chain dysfunction: implications in neurodegeneration.
For decades mitochondria have been considered static round-shaped organelles in charge of energy production. In contrast, they are highly dynamic cellular components that undergo continuous cycles of fusion and fission influenced, for instance, by oxidative stress, cellular energy requirements, or the cell cycle state. New important functions beyond energy production have been attributed to mit...
متن کاملMitochondrial Dysfunction in Neurodegeneration
The mitochondrial respiratory chain (RC) is responsible for providing most of the cellular energy in the form of ATP, and is also one of the main sites of reactive oxygen species (ROS) formation. The RC, consisting of five enzyme complexes in the inner mitochondrial membrane, is unique in its bipartite dependence on both nuclear and mitochondrial DNA (mtDNA). One example of this is mitochondria...
متن کاملTopic: Mitochondrial Dysfunction in Neurodegeneration
Neurodegenerative diseases such as Parkinson's disease (PD) are of growing public health concern in developed countries and the need for novel effective treatments continues to increase. Neurodegenerative diseases take many forms, reflecting the degeneration of different populations of neurons at different times from distinct causes, but many of them also share common features. Amongst the comm...
متن کاملImplications of mitochondrial dynamics on neurodegeneration and on hypothalamic dysfunction
Mitochondrial dynamics is a term that encompasses the movement of mitochondria along the cytoskeleton, regulation of their architecture, and connectivity mediated by tethering and fusion/fission. The importance of these events in cell physiology and pathology has been partially unraveled with the identification of the genes responsible for the catalysis of mitochondrial fusion and fission. Muta...
متن کاملMitochondrial dysfunction and neurodegeneration in multiple sclerosis
Multiple sclerosis (MS) has traditionally been considered an autoimmune inflammatory disorder leading to demyelination and clinical debilitation as evidenced by our current standard anti-inflammatory and immunosuppressive treatment regimens. While these approaches do control the frequency of clinical relapses, they do not prevent the progressive functional decline that plagues many people with ...
