Research highlights
► Oxysterols are 27-carbon-atom products of enzymatic or non-enzymatic oxidation of cholesterol. ► Oxidative stress is the major non-enzymatic source of oxysterols. ► Oxysterols may in turn amplify oxidative redox imbalance in cells and tissues. ► Pathological accumulation of oxysterols triggers and sustains inflammatory reactions. ► Oxysterol-mediated inflammation is a primary mechanism of progression in major chronic diseases.
