Frontotemporal lobar degeneration (FTLD) is a progressive neurodegenerative syndrome. Defects of copper (Cu) and iron (Fe) homeostasis are involved in the development of several neurodegenerative diseases and their homeostasis is interconnected by the Cu-protein ceruloplasmin (Cp), responsible for Fe oxidative state. In this study we assessed Fe, transferrin (Trf), ferritin, Cp specific activity (eCp/iCp), Cp/Trf ratio, and Trf saturation in 60 FTLD patients and 43 healthy controls, and discussed the results in relation to Cu homeostasis. The significant decrease of the eCp/iCp in the FTLD patients supports the involvement of Fe imbalance in the onset and progression of FTLD.
额颞叶变性(FTLD)是一种进行性神经退行性综合征。铜(Cu)和铁(Fe)稳态的缺陷与几种神经退行性疾病的发展有关,其稳态通过铜蛋白铜蓝蛋白(Cp)相互关联,Cp 负责 Fe 的氧化状态。在这项研究中,我们评估了 60 名 FTLD 患者和 43 名健康对照者的 Fe、转铁蛋白(Trf)、铁蛋白、Cp 比活性(eCp/iCp)、Cp/Trf 比值和 Trf 饱和度,并讨论了与 Cu 稳态的关系。FTLD 患者 eCp/iCp 的显著降低支持 Fe 失衡参与 FTLD 的发病和进展。
