Magnetic resonance imaging biomarkers of exercise‐induced improvement of oxidative stress and inflammation in the brain of old high‐fat‐fed ApoE−/− mice

Vascular brain lesions and atherosclerosis are two similar conditions that are characterized by increased inflammation and oxidative stress. Non‐invasive imaging in a murine model of atherosclerosis showed vascular brain damage and peripheral inflammation. In this study, exercise training reduced magnetic resonance imaging‐detected abnormalities, insulin resistance and markers of oxidative stress and inflammation in old ApoE−/− mice. Our results demonstrate the protective effect of exercise on neurovascular damage in the ageing brain of ApoE−/− mice.
