Overactive Cell Metabolism Linked to Biological Aging

Human cells with impaired mitochondria expend more energy. While this hypermetabolism enhances a cell's short-term survival, it also dramatically increases the rate at which the cell ages.

Looking to Mitochondria for Clues About Depression

People with untreated depression have lower levels of mitochondrial proteins. For those who responded to the SSRI antidepressants, the proteins returned to a normal level, but showed no increase in those who did not respond to medication.

New Insights on ALS May Point To a Potentially Promising Treatment Strategy

Post-mortem studies of brain tissue from ALS patients reveal an abnormal form of tau is present in novel brain areas, and the tau interacts with DRP1. The tau appears to cause the brain cell's mitochondria to fragment and increase oxidative stress. Reducing tau reversed the effect, decreasing oxidative stress and mitochondrial fragmentation.
