Exercise can protect brain against ageing | Good Health Tips
New York: Daily exercise can protect the brain against decline as we age, finds researchers after conducting an animal study. In lab tests with mice, researchers from Johns Hopkins University found that exercise helped boost levels of an enzyme called SIRT3 which may protect against stressors that contribute to brain cell energy loss. In tests with mice, researchers discovered that exercise helped boost levels of an enzyme called SIRT3, which may protect against stressors that contribute to brain cell energy loss. Researchers led by Mark Mattson from the National Institute on Aging and Johns Hopkins' school of medicine used a new animal model to investigate whether they could aid neurons in resisting the energy-depleting stress. They found that mice that did not produce SIRT3 became highly sensitive to stress when exposed to neurotoxins that cause neurodegeneration and epileptic seizures. With mice that did produce SIRT3, researchers discovered that exercise on a running wheel
