Fig. 1: α-Syn PFFs induce mitochondrial fragmentation.

a, b Images of mitochondria in dendrites and axons. Both dendritic and axonal mitochondria showed reduced length in α-Syn PFFs-treated neurons. c) Images of p-α-Syn accumulation. d, e Quantification of dendritic and axonal mitochondrial length using MitoVis. nControl = 22 neurons, nα-Syn = 23 neurons. Samples were obtained from 4 independent experiments from different pups. Number of mitochondria is annotated at the bottom of bar graphs. Unpaired t-test, ****p < 0.0001, a, c Scale bar = 20 μm, b Scale bar = 5 μm.
