Comparing 2 hypotheses side-by-side
Cytosolic Hsp70 (HSPA1A) stabilizes lysosomal membranes under stress by preventing phase transition and cardiolipin oxidation. AAV delivery of HSPA1A would increase lysosomal membrane resilience to Aβ42 and oxidative stress. However, Hsp70 has pleiotropic effects beyond lysosomal stabilization (protein folding, anti-apoptotic, immune modulation), complicating mechanism attribution. The therapeutic approach is indirect.
**Background and Rationale** The apolipoprotein E epsilon 4 allele (APOE4) represents the strongest genetic risk factor for late-onset Alzheimer's disease, increasing risk 3-fold in heterozygotes and 8-15-fold in homozygotes. While traditional research has focused on APOE4's effects on amyloid-β clearance and lipid transport, emerging evidence suggests that the structural instability of APOE4 itself creates a fundamental proteostasis crisis that drives neurodegeneration through multiple converg
