**CYP46A1 Overexpression Gene Therapy for Alzheimer's Disease** **Overview and Rationale** Cholesterol homeostasis in the brain is a critical factor in Alzheimer's disease (AD) pathogenesis. Unlike peripheral tissues, the brain maintains autonomous cholesterol metabolism due to the blood-brain barrier preventing lipoprotein exchange. Cholesterol 24-hydroxylase (CYP46A1) is the rate-limiting enzyme for brain cholesterol elimination, converting cholesterol to 24S-hydroxycholesterol (24-OHC), whi
## Molecular Mechanism and Rationale The core mechanism centers on TREM2's role in regulating cholesterol homeostasis through modulation of CYP46A1 expression, where TREM2 deficiency disrupts the normal cholesterol efflux pathway in microglia. Under physiological conditions, TREM2 signaling through SYK and PI3K/AKT pathways promotes CYP46A1 expression, facilitating cholesterol 24-hydroxylation and subsequent efflux via ABCA1/ABCG1 transporters. When TREM2 function declines with aging or genetic
