Boosting neuronal activity-driven mitochondrial DNA transcription improves cognition in aged mice.

Deciphering the complex interplay between neuronal activity and mitochondrial function is pivotal in understanding brain aging, a multifaceted process marked by declines in synaptic function and mitochondrial performance. Here, we identified an age-dependent coupling between neuronal and synaptic excitation and mitochondrial DNA transcription (E-TC), which operates differently compared to classic excitation-transcription coupling in the nucleus (E-TC). We demonstrated that E-TC repurposes molecules traditionally associated with E-TC to regulate mitochondrial DNA expression in areas closely linked to synaptic activation.
