Summary

The active transport of cholesterol out of cells, primarily mediated by ABCA1 and ABCG1 transporters in macrophages and microglia. Cholesterol efflux to apolipoproteins (APOE, APOA1) is critical for reverse cholesterol transport and lipid homeostasis in the brain. Impaired efflux promotes foam cell formation and contributes to atherosclerosis and neurodegeneration.
