ABSTRACT
Disrupted axonal transport and astrocyte dysfunction are implicated in amyotrophic lateral sclerosis (ALS). Here we show these processes are linked-human-induced pluripotent stem-cell-derived astrocytes carrying the C9ORF72 mutation disrupt mitochondrial axonal transport and mitochondrial function in cocultured motor neurons (MNs). Conversely, isogenic gene-corrected astrocytes or boosting astrocytic mitochondrial bioenergetics rescue axonal mitochondrial transport deficits in C9ORF72 MNs. Our results delineate a non-cell-autonomous role for astrocytes in regulating mitochondrial transport along axons in ALS models.
