Abstract:Endothelial cell activation drives early atherosclerotic plaque formation. Both fibronectin deposition and accumulation of oxidized LDL (oxLDL) occur early during atherogenesis and both are implicated in enhanced endothelial cell activation. However, interplay between these responses has not been established. We now show that oxLDL-induced NF-κB activation, proinflammatory gene expression, and monocyte binding is significantly enhanced when endothelial cells are attached to fibronectin compared to basement mem… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
