Mitochondrial and lysosomal dysfunction are central to Parkinson’s disease (PD) pathogenesis. Here, the authors show mitochondrial dsDNA in the cytosol in cellular and Zebrafish models of PD induces cytotoxicity and neurodegeneration; knock-down of IFI16, a cytosolic dsDNA sensor, rescues cytotoxicity, as does overexpression of lysosomal DNAse II.
