Single-cell analysis of AD brains will reveal a distinct astrocyte subpopulation characterized by upregulated xanthine oxidoreductase (XOR), hexokinase 2 (HK2), and aldehyde dehydrogenase 2 (ALDH2) expression, representing a metabolic reprogramming toward purine metabolism and oxidative stress response. This 'stress-responsive astrocyte' (SRA) state differs from canonical disease-associated astrocytes (DAAs) and is preferentially enriched in regions with high tau burden (entorhinal cortex, hippo
