Melatonin prevents brain aging due to mitochondrial dysfunction
Reactive oxygen species (ROS) are considered a key factor in brain aging process. Complex I of the mitochondrial respiration chain is an important site of ROS production and hence a potential contributor to brain functional changes with aging. Appropriate antioxidant strategies could be particularly useful to limit this ROS production and associated mitochondrial dysfunction ... more
