How cells recycle damaged mitochondria in middle age may be critical for brain health Mitochondria play an essential role in maintaining cellular health. When damaged, they are removed through a recycling process called mitophagy, which is crucial for the function of long-lived cells, especially in the brain. Impaired mitophagy has been strongly associated with neurodegenerative disorders like Alzheimer's and Parkinson's disease, making it a critical focus for drug discovery and therapeutic innovation.
