OStéopontin as a Marker Of StenoSIS - OSMOSIS

Our hypothesis is that a plasma protein named osteopontin (OPN) could serve as a biological predictive marker of acute AVF dysfunction. In several scientific studies, plasma OPN was correlated with coronary stent restenosis, and with cardiovascular outcome in patients with diabetes and renal insufficiency. This protein is secreted by several cellular types, like distal tubule epithelial cells, macrophages, but also fibroblasts and cardiac and vascular endothelial cells, in resp...
