  • Title: Oxidized lipoproteins and macrophages.
    Author: Jessup W, Wilson P, Gaus K, Kritharides L.
    Journal: Vascul Pharmacol; 2002 Apr; 38(4):239-48. PubMed ID: 12449020.
    Abstract:
    Macrophages are important participants in the development of atherosclerotic lesions, in cholesterol accumulation, as mediators of the immune response, and as sources of secreted enzymes and growth factors. Besides potentially contributing to local oxidation of lesion lipoproteins, many aspects of macrophage function can be affected by interaction with oxidized lipoproteins. Here we review macrophage responses to oxidized lipoproteins and provide novel data on the effects of a major oxidation product, 7-ketocholesterol, on high-density lipoprotein (HDL) function in cholesterol removal from macrophages.
