pubmed:abstractText
To study the interactions of lipoproteins, connective tissue components and cells, mouse peritoneal macrophages were incubated in the presence of human low density lipoproteins (LDL) that had been complexed with pig aortic proteoglycans (PG) or incubated in the presence of soluble collagen and/or lysyl oxidase, which catalyses the formation of cross-linkages in collagen and elastin by oxidising epsilon-amino groups of lysine residues to aldehydes. Soluble and insoluble PG-LDL complexes increased the incorporation of [3H]oleate into cellular cholesteryl esters (CE) 1.6- and 2.8-fold, respectively, while LDL incubated with collagen and lysyl oxidase had no effect compared to control LDL. As judged on the basis of incubations with fucoidin, spermine and 125I-labelled lipoproteins, the mechanism of internalisation of the PG-LDL complexes is different from that of acetylated LDL or dextran sulphate-LDL complexes. The formation of PG-LDL complexes in the arterial intima may lead to an increased uptake of lipoproteins by intimal macrophages during the early phase of atherogenesis.
