Mitochondrial transport defects are implicated in neurodegenerative diseases like amyotrophic lateral sclerosis (ALS). This review explores the role of mitochondrial transport in ALS pathogenesis.
Area of Science:
- Neuroscience
- Cell Biology
- Genetics
Background:
- Perturbation of organellar axonal transport is linked to neurodegenerative diseases.
- Mitochondria appear to be primarily affected by transport defects in certain conditions.
- Amyotrophic lateral sclerosis (ALS) involves complex pathogenic mechanisms.
Purpose of the Study:
- To review current knowledge on mitochondrial transport.
- To elucidate the role of mitochondrial transport in ALS.
Main Methods:
- Literature review of studies on mitochondrial transport and ALS.
- Analysis of genetic mutations associated with familial ALS (fALS).
Main Results:
- Growing evidence points to mitochondrial transport defects in neurodegeneration.
- fALS-associated mutations affect diverse cellular functions, including axonal transport.
Conclusions:
- Mitochondrial transport is a critical factor in neurodegenerative processes.
- Understanding mitochondrial transport is key to unraveling ALS pathogenesis.

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,...
