During aging, decreased efficiency of nuclear factor E2-related factor 2 (Nrf2) activation and autophagic processes in the brain may be a contributing factor in the pathogenesis of neurodegenerative diseases such as Alzheimer’s disease. Therefore, we analyzed the expression of BAG3, a co-chaperone that mediates autophagy, and the autophagy adaptors NBR1, NDP52 and SQSTM1/p62 in the brains of 4, 8 and 12 month old wild-type and Nrf2 knockout (−/−) mice. We also analyzed the levels of total tau, as well as phospho-tau species. There were minimal differences in the expression of autophagy-related genes or tau species in 4 month old animals, however by 12 months all of these autophagy-associated genes were expressed at significantly lower levels in the Nrf2(−/−) mice. The decreases in the autophagy associated genes was accompanied by significantly elevated levels of phospho-tau species in the 12 month Nrf2(−/−) brains. These findings indicate that Nrf2 regulation of autophagy-related genes likely plays a greater role in mediating the clearance of tau as an organism ages.
