Mitophagy, the cellular process that dismantles broken mitochondria, was named by Norwegian biochemist Per Ottar Seglen in 2005. Its slow failure with age is now considered a driver of aging itself, not just a consequence — and the same pathway that fails catastrophically in early-onset Parkinson's fades gently in everyone else. The post Mitophagy is the cellular housekeeping that dismantles broken mitochondria — it changes with age, and researchers now see that faltering maintenance as one of a
