Neurodegenerative diseases, including Parkinson’s disease, are linked to the accumulation of defective mitochondria in the brain and to microbial dysbiosis in the gut. However, the interplay between these factors is incompletely understood. Fedele et al. reveal how gut mitochondrial dysfunction activates intestinal inflammation to drive neurodegeneration in a Parkinson’s disease model.
