This suggested that 6-OHDA-induced activation of NRs might modulate the expression of DMT1 and Fpn1 via the neuronal nitric oxide synthase-IRP1 pathway.-Xu, H., Liu, X., Xia, J., Yu, T., Qu, Y., Jiang, H., Xie, J., Activation of NMDA receptors mediated iron accumulation via modulating iron transporters in Parkinson's disease.
The reduction of iron in neuronal cells by the increased expression of Fpn1 might be partly associated with the beneficial effects of ASA on mood disorders, AD and PD.
Based on our previous in vivo experiments showing that down-regulation of the iron transporters ferroportin 1 (FP1) and hephaestin (HP) might account for the nigral iron accumulation in 6-hydroxydopamine (6-OHDA)-lesioned animal models, in this study we investigated whether FP1 and HP were involved in cellular iron accumulation and the underlying mechanisms in a cell model of PD.
