Amyloid protein aggregates: new clients for mitochondrial energy production in the brain?

Mitochondria are key organelles, which maintain energy metabolism and cellular homeostasis. Mitochondria support transcriptional regulation and proteostatic signaling mechanisms through crosstalk between the mitochondria itself, the nucleus, and the cytoplasm. Mitochondrial dysfunction leads to impaired proteostasis, and both are key pathological features of age-related neurological disorders.
