Mitochondrial ‘Suicide’ May Signal Start of Neurodegeneration in ALS, Mouse Study Suggests
A newly discovered self-destructive mechanism in mitochondria, the cells’ powerhouses, may be one of the first deficits leading to motor neuron degeneration associated with toxic TDP-43 clumps — a hallmark of amyotrophic lateral sclerosis (ALS). That evidence from a preclinical study suggests available therapies against mitochondrial degeneration might help halt neurodegeneration…
