Comparing 2 hypotheses side-by-side
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
Despite different initial triggers (LPS, β-amyloid, aging), primed microglia may converge on a common 'epigenetic priming signature' characterized by BRD4-occupied poised enhancers at NF-κB target genes (including TNF, IL1B, CCL2, and TREM2). This convergent chromatin remodeling would explain why BET inhibitors produce similar therapeutic effects regardless of priming stimulus, as they disrupt a shared downstream transcriptional amplifier rather than stimulus-specific upstream pathways. The test
