Manganese and iron are essential trace elements involved in critical neuronal processes; however, excessive exposure to these metals is a significant risk factor for Alzheimer's disease (AD). While most previous studies have focused on single-metal neurotoxicity, the mechanisms underlying combined manganese and iron exposure remain unclear. In this study, we investigated the effects of manganese and iron exposure, both individually and in combination, on tau hyperphosphorylation, β-amyloid (Aβ) accumulation (particularly Aβ Show less
