Background: The cerebellum is an area of the brain that is prone to damage in individuals with Alzheimer’s disease (AD). As a non-pharmacological intervention for AD, exercise training has shown an ameliorating effect on AD pathology; however, the target regions have mostly been the cerebral cortex and hippocampus. The main aim of this study was to explore the influence of 12 weeks of treadmill running on the accumulation of AD-related proteins, dysfunction of mitochondria, and subsequent neuronal cell death in the cerebellum of triple transgenic (3xTg-AD) mice. Methods: Four-month-old 3xTg-AD mice were allocated into two groups: an AD control group (AD, n = 10) and an AD exercise group (AD-Exe, n = 10). The AD-Exe mice underwent training on a motorized animal treadmill 5 days a week for 12 weeks. After sacrifice, the cerebellum was collected and biochemically analyzed. Results: The AD-Exe mice expressed reduced levels of extracellular β-amyloid plaques and phosphorylated tau (p-tau), and showed improved Purkinje cell survival and mitochondrial function compared with AD mice. Conclusions: These findings suggest that engaging in exercise training can offer protection against the progression of AD in the cerebellum by enhancing mitochondrial function and promoting cell survival. |
