Researchers discover mechanism that can protect from aging processes

Humans are getting older and older, and the number of people with dementia is increasing. The factors controlling degeneration of the brain are still mostly unknown. However, researchers assume that factors such as stress, accumulation of toxic waste products as well as inflammation accelerate aging. But, vice versa, there are also mechanisms that can - like a bodyguard - protect the brain from degenerating, or repair defective structures.
