This short, enlightening video clip is an extract from a FoundMyFitness interview with Dr. Guido Kroemer. PD is characterized by protein aggregation of a-synuclein and mitochondrial dysfunction, partly due to mitophagy failure. A recently proposed strategy in preventing (or perhaps treating) neurodegenerative diseases like PD is to starve the cells or use biochemical methods to induce general autophagy and thus help the cell rid itself of protein aggregates. Here Dr. Kroemer describes how mitophagy contributes to the pathophysiology of neurodegenerative diseases like PD and Alzheimer’s and how autophagy might mitigate these processes.
