Atherosclerosis Is Attenuated by Limiting Superoxide Generation in Both Macrophages and Vessel Wall Cells
Abstract
Objective— We previously showed that NAD(P)H oxidase deficiency significantly reduces atherosclerosis in apoE −/− mice. The present study was designed to determine the relative contribution of monocyte/macrophage versus vascular wall cell NAD(P)H oxidase to atherogenesis in this model. Methods and Results— Cell-specific NAD(P)H oxidase inhibition was achieved via allogenic, sex-mismatched bone marrow transplantation. Aortic atherosclerosis and superoxide production in apoE −/− mice (Control) with functional NAD(P)H oxidase in both monocytes/macrophages and vascular wall cells was compared with that in apoE −/− mice with nonfunctional monocyte/macrophage NAD(P)H oxidase (BMO) or nonfunctional vessel wall NAD(P)H oxidase (VWO). A significant decrease in superoxide production and atherosclerotic lesions was observed in BMO and VWO mice compared with control mice. Interestingly, BMO mice had significantly lower plasma oxidized LDL levels compared with control and VWO mice, whereas aortic sections of VWO mice showed decreased expression of cellular adhesion molecules compared with control and BMO mice. NAD(P)H oxidase deficiency also attenuated neointimal hyperplasia and mitogenic protein activation in apoE −/− mice after arterial injury. Conclusions— We conclude that (1) both monocyte/macrophages and vessel wall cells play critical roles in atherogenesis; (2) decrease in atherosclerosis results from attenuated superoxide generation in monocyte/macrophages or vessel wall cells; and (3) superoxide generation may impact atherosclerosis, in part, by activating smooth muscle cell mitogenic signaling pathways.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
