Novel atherosclerosis biomarkers are in need to improve the strategies for diagnosis and prognosis of cardiovascular disease. CNIC and DKFZ researchers have discovered 18 novel antibodies that show reactivity against the atherosclerotic plaque, which can thus be potentially used for the diagnosis of this disease. Moreover, the use of one such antibody, A12, delays the progression of atherosclerosis and reduces the level of free circulating cholesterol and LDL.
