Emerging role of Toll-like receptors in atherosclerosis

Abstract

Atherosclerosis is inflammation of the vessel wall of the arterial tree. This inflammation arises at specific areas that experience disturbed blood flow such as bifurcations and the lesser curvature of the aortic arch. Although all endothelial cells are exposed to comparable levels of circulating plasma cholesterol, only endothelial cells overlaying lesions display an inflamed phenotype. This occurs even in the absence of any additional exacerbating disease factors because blood flow controls the expression of Toll-like receptors (TLR), which are initiators of cellular activation and inflammation. TLR2- and 4-expression exert an overall proatherogenic effect in hyperlipidemic mice. TLR activation of the endothelium promotes lipid accumulation and leukocyte accumulation within lesions.

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.
