Abstract
Dysregulation of iron metabolism has been observed in patients with
neurodegenerative diseases (NDs).
Utilization of several importers and exporters for iron transport in
brain cells helps maintain iron homeostasis. Dysregulation of iron
homeostasis leads to the production of neurotoxic substances and
reactive oxygen species, resulting in iron-induced oxidative stress.
In Alzheimer's disease (AD) and Parkinson's disease (PD),
circumstantial evidence has shown that dysregulation of brain iron
homeostasis leads to abnormal iron accumulation.
Several genetic studies have revealed mutations in genes associated
with increased iron uptake, increased oxidative stress, and an altered
inflammatory response in amyotrophic lateral sclerosis (ALS).
Here, we review the recent findings on brain iron metabolism in common
NDs, such as AD, PD, and ALS.
We also summarize the conventional and novel types of iron chelators,
which can successfully decrease excess iron accumulation in brain
lesions.
For example, iron-chelating drugs have neuroprotective effects,
preventing neural apoptosis, and activate cellular protective pathways
against oxidative stress.
Glial cells also protect neurons by secreting antioxidants and
antiapoptotic substances.
These new findings of experimental and clinical studies may provide a
scientific foundation for advances in drug development for NDs.
