Title	Mitochondrial reprogramming using dCas9 boosts glia-to-neuron conversion
Description	Astrocyte-to-neuron conversion has developed into a promising avenue for neuronal replacement therapy. Neurons depend critically on mitochondria function and often die by ferroptosis during the conversion process. Here we examined the extent of adequate mitochondrial reprogramming by morphology and proteome analysis. While mitochondria profoundly changed their morphology during Neurogenin2 (Neurog2) – or Achaete-scute homolog 1 (Ascl1)-mediated astrocyte-to-neuron reprogramming, we found neuron-specific mitochondrial proteins, here identified in a comprehensive proteome analysis of isolated mitochondria from primary neurons and astrocytes, to be only partially and at late stages regulated during the process. To improve this, we used dCas9 technology to induce neuron-specific mitochondrial proteins early during reprogramming. This resulted not only in increased conversion efficiency, but also in faster neuronal generation. Taken together, reprogramming mitochondria in a cell type-specific manner has powerful effects on astrocyte-to-neuron conversion, suggesting mitochondria to be a driving force in this process.
