Brain aging and neurodegeneration: from a mitochondrial point of view
Aging is defined as a progressive time-related accumulation of changes responsible for or at least involved in the increased susceptibility to disease and death. The brain seems to be particularly sensitive to the aging process since the appearance of neurodegenerative diseases, including Alzheimer's disease, is exponential with the increasing age. Mitochondria were placed at the center of the ...
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 کاملMitochondrial dynamics in neurodegeneration: from cell death to energetic states
From Parkinson’s disease to an ischemic stroke, a consistently reoccurring theme in the context of neuronal degeneration is the dysfunction of mitochondria as the underlying factor. Insight into the mechanistic basis for mitochondrial dysfunction in neurodegenerative disorders has allowed the theme of mitochondrial dynamics to be highlighted as a central player. The precise balance of mitochond...
متن کاملBrain Mitochondrial Dysfunction in Aging, Neurodegeneration, and Parkinson's Disease
Brain senescence and neurodegeneration occur with a mitochondrial dysfunction characterized by impaired electron transfer and by oxidative damage. Brain mitochondria of old animals show decreased rates of electron transfer in complexes I and IV, decreased membrane potential, increased content of the oxidation products of phospholipids and proteins and increased size and fragility. This impairme...
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...
