Iron Accumulation in Neurons

Molecular classification
Other
01

Overview

Iron accumulation in neurons refers to the pathological buildup of iron within neuronal cells, a phenomenon observed in normal aging and various neurodegenerative diseases. While iron is essential for numerous cellular processes, its dysregulation can lead to oxidative stress and neuronal damage. Several mechanisms contribute to abnormal neuronal iron buildup, including increased uptake/reduced export, sequestration, and metabolic disturbances. Reducing excessive neuronal/labile brain iron using chelators capable of crossing the blood-brain barrier has shown promise experimentally.
