What specific microglial factors mediate iron-induced neurotoxicity in the tri-culture system?

While removal of microglia delayed iron-induced neurodegeneration, the specific toxic factors or pathways released by iron-loaded microglia that damage neurons are not identified. This mechanistic gap limits understanding of how microglial ferroptosis contributes to neuronal death.
