From: Human macrophages limit oxidation products in low density lipoprotein
Effect of LDL and oxLDL on the intracellular antioxidant defenses in macrophages. The intracellular activity of catalase (A), glutathione peroxidase (B), and the levels of glutathione (C) were measured in crude extracts from macrophages (n = 6) incubated with LDL or oxLDL (oxidized for 2 h). Control cells were incubated in the absence of LDL. Results were analyzed by ANOVA.
