Spatial redistribution of GFAP from astrocyte end-feet to soma — not upregulation — is the mechanistically relevant BBB-dysfunction event, detectable as altered plasma/CSF GFAP ratio and AQP4 depolarization before reactive gliosis onset.

## Mechanistic Overview GFAP-Positive Reactive Astrocyte Subtype Delineation starts from the claim that modulating GFAP within the disease context of Alzheimer's Disease can redirect a disease-relevant process. The original description reads: "GFAP (Glial Fibrillary Acidic Protein) upregulation in the SEA-AD dataset marks reactive astrocyte populations in the middle temporal gyrus with a log2 fold change of +2.8 — the highest differential expression among all profiled genes. This dramatic increa
