Accumulation of substantial numbers of monocyte/macrophages, as well as activated T lymphocytes, in focal areas of arterial intima appears to be a hallmark of atherogenesis. Our report demonstrated that lysophosphatidylcholine (lyso-PC), a polar phospholipid component that is increased in atherogenic lipoproteins, such as oxidized LDL and remnants lipoproteins in diabetic and type III hyperlipidemic patients, can upregulate adhesion molecules for monocytes and T lymphocytes, and growth factors, such as heparin-binding epidermal growth factor-like growth factor and PDGF-A and B chains. Recently we identified the novel receptor for oxidized LDL, named Lox-1. Therefore in this paper we summarize the importance of the interaction between oxidized LDL and its receptor, LOX-1 in terms of early stage of atherogenesis.
