APOE4’s role in brain vascular and cellular dysfunction is examined in a research-feature article explaining experimental modeling and therapeutic avenues.
Key Takeaways
- APOE4 drives pericytes to transdifferentiate into scar-producing myofibroblast-like cells, causing vascular fibrosis and amyloid deposition.
- Blocking TGF-β signaling reversed vascular degeneration and restored vessel integrity in aged mouse models described in the study.
- APOE4 causes abnormal cholesterol accumulation in astrocytes in 3D stem cell-derived miBrains, impairing cellular waste clearance.
