Neuroinflammation and microglial priming in early AD

PARTIALLY ADDRESSED

How does microglial priming contribute to early Alzheimer's disease pathology? Focus on the mechanisms by which peripheral inflammation, aging, and genetic risk factors (e.g., APOE4, TREM2) prime microglia toward an inflammatory phenotype. Investigate the role of cytokines, damage-associated molecular patterns (DAMPs), and metabolic shifts in microglial activation states during the prodromal phase of AD.
