Abstract:Objective To investigate the effect of macrophage-myeloperoxidase on LDL oxidation. Methods Based on the model of rat macrophage,we investigated the relation between macrophage-myeloperoxidase and LDL oxidation by measuring macrophage-myeloperoxidase activation,LDL oxidation products and cell cholesterol.Results LDL promoted cell and secretive myeloperoxidase activation which was concentration-dependent with LDL;with elevation of myeloperoxidase activation,LDL oxidation increased and NaN3 inhibited this effect;taurine partially protected against LDL oxidation by HOCl,and protected against accumulation of cell cholesterol.Conclusion LDL induced the elevation of macrophage-myeloperoxidase to enhance its own oxidation and absorption.
