Abstract

We found that several transposable elements were highly active in Drosophila brain during normal aging. In addition, we found that mutations in Drosophila Argonaute 2 (Ago2) resulted in exacerbated transposon expression in the brain, progressive and age-dependent memory impairment, and shortened lifespan. These findings suggest that transposon activation may contribute to age-dependent loss of neuronal function.
