# APOE4-Specific Microglial Metabolic Rescue Hypothesis
## Molecular Mechanism and Rationale
The APOE4-specific microglial metabolic rescue hypothesis centers on the fundamental disruption of lipid metabolism and cholesterol homeostasis in microglia carrying the APOE4 allele. Unlike APOE2 and APOE3, the APOE4 isoform exhibits reduced binding affinity to the low-density lipoprotein receptor (LDLR) and altered interactions with ATP-binding cassette transporter A1 (ABCA1).
