SCARB1 and atherosclerosis: These findings suggested that monocytes from SR-BI−/− mice have increased capacity for recruitment into atherosclerotic plaques and that the reduced atherosclerosis in SR-BI+/+→SR-BI−/− mice compared to the SR-BI−/−→SR-BI−/− mice may be because restoration of SR-BI expression in BM derived cells reduces monocyte recruitment into developing atherosclerotic plaques.
