The Lectin-like OXidized low-density lipoprotein scavenger receptor (LOX-1) is implicated in vascular inflammation and atherosclerotic plaque initiation, progression, and destabilization. LOX-1 levels are elevated upon recognition of oxidized low-density lipoprotein, a key pro-atherogenic substance in the vasculature. Recent evidence indicates this gene product is a biomarker of inflammation and disease status. We review and assess the role of LOX-1 in atherosclerotic plaque formation, physiologic regulation, and as a biomarker and target in cardiovascular disease diagnosis and prevention.
