Le processus plus puissant que l'autophagie dont personne ne parle

#autophagy #mitophagy #longevity You've heard of autophagy. The cellular self-cleaning process. Nobel Prize winner. The reason some people fast for 16 hours and think they're scientists. But autophagy is general. Massive. Non-selective. There's a more targeted and important version of this process, that almost no one talks about. It identifies and selectively destroys your most dangerous cellular waste—damaged mitochondria—before they release toxic byproducts, trigger inflammation, and cause the diseases most often associated with aging. It's called mitophagy. And the research linking impaired mitophagy to Parkinson's disease, Alzheimer's disease, heart failure, type 2 diabetes, and accelerated cellular aging is not fringe. It represents the current consensus in cell biology. In this video, We explore mitophagy in detail: its definition, its difference from autophagy, the consequences of its dysfunction, and above all, the scientifically validated interventions that activate it. No experimental drugs. No rare genetic manipulations. Physical exercise. Fasting. Diet. Hormetic stress. This system is innate. It simply needs the right signal. ────────────────────────────────── ⏱ CHAPTERS 00:00 – Introduction: Beyond Autophagy 02:00 – Part 1: What is it?
