Inhibition of iron-induced cofilin activation and inflammation in microglia by a novel cofilin inhibitor.

ABSTRACT: Neuroinflammatory conditions linked to iron dysregulation pose significant challenges in neurodegenerative diseases. Iron-loaded microglia are observed in the brains of patients with various neuroinflammatory conditions, yet how iron overload affects microglial function and contributes to various neuroinflammatory processes is poorly understood. This in vitro study elucidates the relationship between excess iron, cofilin activation, and microglial function, shedding light on potential therapeutic avenues. Iron overload was induced in Human Microglial Clone 3 cells using ferrous sulfate, and the expressions of ferritin heavy chain, ferritin light chain, divalent metal transporter 1, cofilin, p-cofilin, nuclear factor-κB (NF-κB), and various inflammatory cytokines were analyzed using real-ti
