阿尔茨海默病与铁稳态失常及相关药物研发现状

Disruption of iron homeostasis and relevant pharmacotherapies in Alzheimer's disease

铁是人体含量最多的金属元素,参与多种生理活动,对神经系统功能的发挥也起着重要作用。正常状态下,铁稳态受到严格的调控,铁过量或不足均会引发相应疾病。大量研究显示阿尔茨海默病(Alzheimer’s disease,AD)患者机体铁稳态失常,并且铁稳态的失常与AD标志性病理变化相关。虽然针对AD与铁稳态关系的研究很多,但目前铁在AD发病中的确切地位尚不明确。本文将从生理状态下铁稳态的维持、铁稳态异常在AD发病中发挥的作用和以铁清除为靶点的药物研发现状进行综述。

Iron is the most abundant metal element to support the body＇s physiological activities and play crucial roles in the central nervous system. Iron homeostasis is under strict control in normal circumstances, and some diseases will occur once the homeostasis was disrupted. Numerous researches suggest that iron homeostasis disruptes in Alzheimer＇s disease（AD） and the homeostasis disruption interacts with AD＇s hallmarks. Dispute still exists on how iron plays a role in AD despite of the great number of researches. This article will focus on iron metabolism, normal function in the brain and recent therapies of AD based on iron chelation.
