摘要

Alzheimer’s disease (AD) is rarely addressed in the context of aging even though there is an overlap in pathology. We previously used a phenotypic screening platform based on old age–associated brain toxicities to identify the flavonol fisetin as a potential therapeutic for AD and other age-related neurodegenerative diseases. Based on earlier results with fisetin in transgenic AD mice, we hypothesized that fisetin would be effective against brain aging and cognitive dysfunction in rapidly aging senescence-accelerated prone 8 (SAMP8) mice, a model for sporadic AD and dementia. An integrative approach was used to correlate protein expression and metabolite levels in the brain with cognition. It was found that fisetin reduced cognitive deficits in old SAMP8 mice while restoring multiple markers associated with impaired synaptic function, stress, and inflammation. These results provide further evidence for the potential benefits of fisetin for the treatment of age-related neurodegenerative diseases.
