| Research Abstract |
The aim of this study was to investigate the antiatherogenic actions of lysophospholipid contained in lipoproteins. In the endothelial cells, the antiatherogenic actions of HDL was mediated through two signaling pathways, both sphingosine 1-phosphate(S1P)/S1P receptors and Apo A/scavenger receptor class B type I receptors(SR-BI). LDL inhibited the signal transduction system of Apo A/SR-BI, but not S1P/S1P receptors. The antiatherogenic action of S1P contained in HDL was not inhibited by LDL.
