| pubmed-article:10884299 | pubmed:abstractText | We investigated the mechanism of beta-very low density lipoprotein (beta-VLDL)-induced foam cell formation derived from peritoneal macrophages from control mice and low density lipoprotein (LDL) receptor-deficient mice to elucidate the role of the LDL receptor in this process. The LDL receptor appeared to be of major importance for beta-VLDL metabolism. Consequently, the accumulation of cholesteryl esters in LDL receptor(-)(/)- macrophages is 2.5-fold lower than in LDL receptor(+)(/)(+) macrophages. In the absence of the LDL receptor, however, beta-VLDL was still able to induce cholesteryl ester accumulation and subsequently we characterized the properties of this residual beta-VLDL recognition site(s) of LDL receptor(-)(/)- macrophages. Although the LDL receptor-related protein is expressed on LDL receptor(-)(/)- macrophages, the cell association of beta-VLDL is not influenced by the receptor-associated protein, and treatment of the macrophages with heparinase and chondroitinase was also ineffective. In contrast, both oxidized LDL (OxLDL) and anionic liposomes were able to inhibit the cell association of (125)I-labeled beta-VLDL in LDL receptor(-)(/)- macrophages by 65%. These properties suggest a role for scavenger receptor class B (SR-B), and indeed, in the LDL receptor(-)(/)- macrophages the selective uptake of cholesteryl esters from beta-VLDL was 2.2-fold higher than that of apolipoproteins, a process that could be inhibited by OxLDL, high density lipoprotein (HDL), and beta-VLDL. In conclusion, the LDL receptor on peritoneal macrophages is directly involved in the metabolism of beta-VLDL and the subsequent foam cell formation. When the LDL receptor is absent, SR-B appears to mediate the remaining metabolism of cholesteryl esters from beta-VLDL. | lld:pubmed |
