Electronegative LDL: A Circulating Modified LDL with a Role in Inflammation
Electronegative low density lipoprotein (LDL(-)) is a minor modified fraction of LDL found in blood. It comprises a heterogeneous population of LDL particles modified by various mechanisms sharing as a common feature increased electronegativity. Modification by oxidation is one of these mechanisms. LDL(-) has inflammatory properties similar to those of oxidized LDL (oxLDL), such as inflammatory...
متن کاملGender disparity in LDL-induced cardiovascular damage and the protective role of estrogens against electronegative LDL
BACKGROUND Increased levels of the most electronegative type of LDL, L5, have been observed in the plasma of patients with metabolic syndrome (MetS) and ST-segment elevation myocardial infarction and can induce endothelial dysfunction. Because men have a higher predisposition to developing coronary artery disease than do premenopausal women, we hypothesized that LDL electronegativity is increas...
متن کاملCeramide-enriched LDL induces cytokine release through TLR4 and CD14 in monocytes. Similarities with electronegative LDL.
INTRODUCTION In vitro ceramide-enriched LDL (CER-LDL) reproduces most of the properties of electronegative LDL (LDL(-)), a heterogeneous subfraction of LDL found in plasma. LDL(-) comprises several modifications of LDL and has an increased content in ceramide (CER). It promotes cytokine release in monocytes through CD14 and TLR4. CER-LDL also induces cytokine release in these cells but the mech...
متن کاملLDL phospholipid hydrolysis produces modified electronegative particles with an unfolded apoB-100 protein.
Electronegative low density lipoprotein (LDL(-)) formation that structurally resembles LDL(-) isolated from plasma was evaluated after LDL treatment with snake venom phospholipase A(2) (PLA(2)). PLA(2) treatment of LDL increased its electrophoretic mobility in proportion to the amount of LDL(-) formed without evidence of lipid peroxidation. These changes dose-dependently correlated with the deg...
متن کاملDensity distribution of electronegative LDL in normolipemic and hyperlipemic subjects.
The density distribution of electronegative LDL [LDL(-)], a cytotoxic and inflammatory fraction of LDL present in plasma, was studied in 10 normolipemic (NL), 6 FH, and 11 hypertriglyceridemic (HTG) subjects. Six LDL subclasses of increased density (LDL1 to LDL6) were isolated by density-gradient ultracentrifugation (DGU). NL and FH subjects showed prevalence of light LDL, whereas HTG subjects ...
