APOE aggregation in microglia initiates Alzheimer’s disease pathology by seeding β-amyloidosis
Background: Alzheimer’s disease (AD) is characterized by the accumulation of amyloid-β (Aβ) plaques in the brain, contributing to neurodegeneration. The process by which these plaques form, particularly in sporadic (non-familial) cases of AD, remains not fully understood. Genetic studies have linked the apolipoprotein E (APOE) gene and microglial function—immune cells in the brain—to AD, suggesting…
