Abstract
TMHF elevated brain iron by 22% in humanized mice over twelve months.
- Increasing brain iron levels accelerated the formation of amyloid plaques.
- Higher iron concentrations in the brain were linked to increased staining for amyloid beta.
- Elevated brain iron was associated with greater iron loading in amyloid plaques and microglial iron inclusions.
- TMHF treatment led to decreased microglial branch length and increased roundness, indicating microglial activation.
- Iron deficiency decreased brain iron by 21% compared to a control diet.
