New research from the McWilliams Lab at the University of Helsinki, led by doctoral researcher Anna Rappe, has uncovered an unexpected and dynamic pattern of mitophagy (the process by which damaged mitochondria are removed) in different brain cell types as animals age. In a brain region responsible for movement, mitophagy levels increased with age, while in memory-related brain cells, mitophagy initially rose but then sharply declined in older age.
