Effect of macrophage-derived apolipoprotein E on established atherosclerosis in apolipoprotein E-deficient mice.
Apolipoprotein E-deficient (apoE(-/-)) mice have hyperlipidemia and develop spontaneous atherosclerosis in a time-dependent manner. Although macrophage-derived apoE has been shown to prevent the development of atherosclerosis in apoE(-/-) mice, whether it would induce regression of established atherosclerosis is unknown. To determine this, 8-week-old apoE(-/-) mice were transplanted with apoE(+...
متن کاملMacrophage-derived apolipoprotein E ameliorates dyslipidemia and atherosclerosis in obese apolipoprotein E-deficient mice.
Previous studies have demonstrated that macrophage-derived apolipoprotein E (apoE) reduces atherosclerotic lesion formation in lean apoE-deficient ((-/-)) mice. apoE has also been demonstrated to play a role in adipocyte differentiation and lipid accumulation. Because the prevalence of obesity has grown to epidemic proportions, we sought to determine whether macrophage-derived apoE could impact...
متن کاملMacrophage-specific expression of human apolipoprotein E reduces atherosclerosis in hypercholesterolemic apolipoprotein E-null mice.
apoE deficiency causes hyperlipidemia and premature atherosclerosis. To determine if macrophage-specific expression of apoE would decrease the extent of atherosclerosis, we expressed human apoE in macrophages of apoE-null mice (apoE-/-) and assessed the effect on lipid accumulation in cells of the arterial wall. Macrophage-specific expression of human apoE in normal mice was obtained by use of ...
متن کاملXenogenic macrophage immunization reduces atherosclerosis in apolipoprotein E knockout mice.
Atherosclerosis is a complex chronic inflammatory disease in which macrophages play a critical role, and the intervention of the inflammatory process in atherogenesis could be a therapeutic strategy. In this study, we investigated the efficacy of xenogenic macrophage immunization on the atherosclerotic lesion formation in a model of murine atherosclerosis. Apolipoprotein E knockout (apoE-KO) mi...
متن کاملEffect of dehydroepiandrosterone on atherosclerosis in apolipoprotein E-deficient mice.
AIM Several clinical trials have indicated that dehydroepiandrosterone (DHEA) reduces coronary events associated with atherosclerosis. The aim of this study was to examine the inhibitory effect of DHEA on atherosclerosis and the mechanisms involved. METHODS Apolipoprotein E-knockout (apoE-KO) mice were fed an atherogenic high-cholesterol diet with or without 0.4% (w/w) DHEA for 12 weeks. RE...
