Angiotensin-Converting Enzyme Inhibition Prevents Arterial Nuclear Factor-κB Activation, Monocyte Chemoattractant Protein-1 Expression, and Macrophage Infiltration in a Rabbit Model of Early Accelerated Atherosclerosis
Abstract
Background The migration of monocytes into the vessel wall is a critical event leading to the development of atherosclerosis. Monocyte chemoattractant protein-1 (MCP-1) is the main chemotactic factor involved in this phenomenon, and nuclear factor-κB (NF-κB) is one of the nuclear factors controlling its expression. ACE inhibitors have been useful in some experimental models of atherosclerosis. In this work, we addressed the hypothesis that angiotensin II (Ang II) may be implicated in the recruitment of monocytes into the vessel wall through the activation of NF-κB and the induction of MCP-1 expression. Methods and Results Accelerated atherosclerosis was induced in the femoral arteries of rabbits by endothelial desiccation and atherogenic diet for 7 days. Atherosclerotic vessels exhibited an increase in NF-κB–like activity, and p50 and p65 NF-κB subunits were identified as components of this activity. MCP-1 (mRNA and protein) was also expressed in the injured vessels coincidently with the neointimal macrophage infiltration. ACE inhibition with quinapril reduced these three parameters. In cultured monocytic and vascular smooth muscle cells, Ang II elicited an increase in NF-κB activation and MCP-1 expression that was prevented by preincubation of cells with pyrrolidinedithiocarbamate, an inhibitor of NF-κB activation. Conclusions The present data support a role for Ang II in neointimal monocyte infiltration through NF-κB activation and MCP-1 expression in a model of accelerated atherosclerosis in rabbits. Our results suggest that ACE inhibitors may have a beneficial effect in early atherosclerosis.

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.
