Abstract:
The review discusses the role of mitochondria in multiple sclerosis (MS). Previously, damage to the mitochondria was regarded as a manifestation of secondary damage to axons and neurons, i.e. as a marker of neurodenegation. Recently, the role of mitochondria in the early stages of MS development, when they could participate in the activation of innate immunity and trigger activation of autoimmune responses of acquired immunity, has been increasingly discussed. The role of polymorphism mitochondrial DNA changes in MS is discussed.
Insights
Mitochondria are now recognized as key players in early multiple sclerosis (MS) development, not just markers of nerve damage. Their role in immune activation suggests new therapeutic targets for MS.
Area of Science:
- Neuroimmunology
- Cellular Biology
- Mitochondrial Medicine
Background:
- Mitochondrial damage was historically viewed as a consequence of neurodegeneration in multiple sclerosis (MS).
- Emerging evidence suggests mitochondria play a more active role in the early pathogenesis of MS.
Purpose of the Study:
- To review the evolving understanding of mitochondria's role in multiple sclerosis.
- To explore the involvement of mitochondria in the early immune activation stages of MS.
- To discuss the impact of mitochondrial DNA (mtDNA) polymorphism on MS development.
Main Methods:
- Literature review of current research on mitochondria and multiple sclerosis.
- Analysis of studies investigating mitochondrial function in early MS pathogenesis.
- Examination of genetic studies on mtDNA variations in MS patients.
Main Results:
- Mitochondria are implicated in the activation of innate immunity during the initial phases of MS.
- Mitochondrial dysfunction may trigger autoimmune responses in acquired immunity relevant to MS.
- Polymorphisms in mitochondrial DNA are being investigated for their association with MS susceptibility and progression.
Conclusions:
- The understanding of mitochondria's role in MS has shifted from a passive marker to an active contributor in early disease stages.
- Mitochondria's involvement in immune activation pathways presents potential new therapeutic strategies for MS.
- Further research into mtDNA polymorphism may offer insights into MS etiology and personalized treatment approaches.

Translocation of Proteins into the Mitochondria
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
