A review examined evidence on mitochondrial Complex V, an enzyme involved in producing cellular energy, across several neurodegenerative diseases, including amyotrophic lateral sclerosis/frontotemporal dementia. The evidence links Complex V changes with mitochondrial dysfunction, but provides very limited support that Complex V is a primary cause of neurodegeneration. The authors suggest it may instead be affected by other disease processes and contribute to nerve-cell vulnerability.
Why this matters
The findings point to mitochondrial energy production as a possible part of how nerve cells become vulnerable in ALS and related diseases. However, this review does not show that targeting Complex V would treat or slow ALS. Direct studies in relevant human models and patient tissue are still needed.
Limitations and context
This is a review of existing research, not a new clinical study or treatment trial. The evidence came from varied sources, including laboratory studies, patient-derived cells, animal models and post-mortem tissue, and direct evidence that Complex V drives neurodegeneration remains very limited.
