TL;DR: In MS, IFN‐β may attenuate glial HO‐1 gene induction and aberrant mitochondrial iron deposition accruing from exposure to proinflammatory cytokines and TNF‐α‐challenged astroglia.
Journal ArticleDOI
Role of heme oxygenase-1 in the regulation of manganese superoxide dismutase gene expression in oxidatively-challenged astroglia.
TL;DR: It is demonstrated that antecedent upregulation of HO‐1 is necessary and sufficient for subsequent induction of the MnSOD gene in neonatal rat astroglia challenged with CSH or dopamine, and in astroglial cultures transiently transfected with full‐length human HO‐ 1 cDNA.
Journal ArticleDOI
Cysteamine pretreatment of the astroglial substratum (mitochondrial iron sequestration) enhances PC12 cell vulnerability to oxidative injury.
TL;DR: The aging-associated accumulation of redox-active iron in subcortical astrocytes may facilitate the bioactivation of dopamine to neuronotoxic free radical intermediates and thereby predispose the senescent nervous system to PD and other neurodegenerative disorders.
