Physical exercise modulates iron in Alzheimer’s disease

A recent study found that regular physical exercise modulates iron homeostasis in both the brain and skeletal muscle of mice with Alzheimer's disease. The results suggest that IL-6 is a key modulator of hepcidin in exercise-induced brain iron modulation, which may help explain why exercise is beneficial for AD prevention or treatment.
