Atherosclerosis is a complex and chronic arterial process which is characterized by a remodeling of the vascular wall, associated with inflammatory reactions, proliferation and cell death process, and with accumulation of oxidized lipids among which oxysterols (cholesterol oxidation products) which might play key roles in the initiation and development of atheromatous lesions. Our work performed on U937 and THP1 promonocytic cells, rat aorta embryonic A7R5 cells, and breast carcinoma MCF7 cells (caspase-3 deficient). Different oxysterols, present in large quantity in atheromatous lesions, were used: 7-cétocholestérol (7KC), 7Β-hydroxycholestérol, 25-hydroxycholestérol, cholestérol-5Α, 6Α-ep…
