- 概要:
- Dysregulation of iron homeostasis in brain causes various neurodegenerative disorders. In fact, high concentration of iron is present in brains of patients with Alzheimer’s disease. It was previously reported that CXCL8 protects human neurons from amyloid-β-induced neurotoxicity and that astrocytes have the potential to play important roles in Alzheimer’s disease. In the present study, we examined the effect of desferrioxamine, an iron chelator, on … the expression of CXCL8 in U373MG human astrocytoma cells used as a model of astrocytes. Treatment of the cells with desferrioxamine induced the expression of CXCL8. Pretreatment of the cells with FeSO4 counteracted the positive effect of desferrioxamine on CXCL8 production, suggesting that the effect of desferrioxamine was due to iron chelation. RNA interference experiments showed that HIF-1α was not involved in desferrioxamine-induced CXCL8 expression. We conclude that desferrioxamine induces CXCL8 in astrocytes and the chelation of iron may be a new therapeutic strategy for Alzheimer’s disease. 続きを見る
