Abstract
One-third of microglial cells in the brains of 100-day-old APP-transgenic mice were newly recruited eGFP-expressing cells.
- Reduction of mitochondrial activity is an early event associated with Alzheimer's disease.
- Mitochondrial damage is linked to increased production of reactive oxygen species near amyloid plaques.
- Analyses of cell type-specific effects are complicated due to the impact of mitochondrial damage on all cell types.
- Donor-derived microglia were equally distributed around amyloid plaques, with no observed changes in amyloid levels or microglial coverage.
- Beneficial mitochondrial alterations in the newly recruited microglial cells did not appear to influence amyloidosis during the early phase of deposition.
