To understand the potential mechanisms involved in the beneficial effects of aspirin (ASA) in mood disorders, Alzheimer's (AD) and Parkinson's disease (PD), we investigated the effects of ASA on the expression of iron transport proteins transferrin receptor 1 (TfR1), ferroportin 1 (Fpn1), and iron storage protein ferritin light chain (Ft-L) in interleukin-6 (IL-6)-treated PC-12 cells.
