The generation of reactive oxygen species is a central feature of inflammation that results in the oxidation of host phospholipids. Oxidized phospholipids, such as 1-palmitoyl-2-arachidonyl-sn-glycero-3-phosphorylcholine (OxPAPC), have been shown to inhibit signaling induced by bacterial lipopeptide or lipopolysaccharide (LPS), yet the mechanisms(More)
BACKGROUND Drug-eluting stents reduce the incidence of in-stent restenosis, but they result in delayed arterial healing and are associated with a chronic inflammatory response and hypersensitivity reactions. Identifying novel interventions to enhance wound healing and reduce the inflammatory response may improve long-term clinical outcomes.(More)
Evidence provided by both clinical and pre-clinical studies regarding a central involvement of the receptor for advanced glycation endproducts (RAGE) in vascular disease continues to mount. RAGE is upregulated as a consequence of activation of the ubiquitous pro-inflammatory transcription factor NF-kappaB which is activated in response to diverse(More)

Current strategies to lower the incidence of ISR (in-stent restenosis) following PCI (percutaneous coronary intervention) are aimed at modifying arterial healing after stent injury. This can impair endothelial recovery and render the vessel prone to acute thrombosis. As early restoration of endothelial integrity inhibits neointimal growth and thrombosis,(More)
A hallmark of many inflammatory diseases is the destruction of tissue cells by infiltrating hematopoietic cells including lymphocytes, neutrophils, and macrophages. The regulation of apoptosis of both target tissue cells and the infiltrating cells is one of the key events that defines the initiation and the progression of inflammation. However, the precise(More)
AIMS The long-term failure of autologous saphenous vein bypass grafts due to neointimal thickening is a major clinical burden. Identifying novel strategies to prevent neointimal thickening is important. Thus, this study aimed to identify microRNAs (miRNAs) that are dysregulated during neointimal formation and determine their pathophysiological relevance(More)
AMP-activated protein kinase (AMPK) is proposed to be a key regulator of cellular and organismal metabolism and has reported vasculoprotective effects. In addition, many therapeutic agents used in the treatment of diabetes and atherosclerosis such as metformin, thiazolidinediones and statins may exert their vasculoprotective effects through activation of(More)
The calgranulin-like protein MTS1/S100A4 and the receptor for advanced glycation end-products (RAGE) have recently been implicated in mediating pulmonary arterial smooth muscle cell proliferation and vascular remodelling in experimental pulmonary arterial hypertension (PH). Here, the effects of RAGE antagonism upon 2 weeks of hypobaric hypoxia (10%(More)
