Macrophages and oxidized LDLs play a key role in atherogenesis but their
heterogeneity has been neglected up to now. Macrophages are prone to polarization
and subsets of polarized macrophages have been described in atheromas. LDLs can
be oxidized not only chemically by copper (Ox-LDLs) but also enzymatically by
myeloperoxidase (MpOx-LDLs) resulting in oxidized LDLs poor in lipid peroxides.
The effects of physiologically relevant myeloperoxidase-oxidized LDLs on
macrophage polarization or on polarized macrophages remain largely unknown. In
this study, the effects of LDLs on macrophage polarization were investigated by
monitoring the expression of M1 and M2 genes following stimulation with native
LDLs, Ox-LDLs, or MpOx-LDLs in RAW 264.7 cells. Except for MRC1, which is induced
only by Ox-LDLs, MpOx-LDLs induced an overexpression of most of the selected
marker genes at the mRNA level. MpOx-LDLs also modulate marker gene expression in
polarized macrophages favoring notably anti-inflammatory Arg1 expression in M2
cells and also in the other phenotypes. Noteworthy, MpOx-LDLs were the most
efficient to accumulate lipids intracellularly in (un)polarized macrophages
whatever the phenotype. These data were largely confirmed in murine bone
marrow-derived macrophages. Our data suggest that MpOx-LDLs were the most
efficient to accumulate within cells and to enhance an anti-inflammatory and
antioxidant phenotype in M2 cells and also in the other macrophage phenotypes.
