ARDS blood vascular proteomics show that low platelet levels track with loss of platelet-derived trophogens, including CD40 ligand (CD40LG), glycoprotein 6 (GP6), ANGPT1, matrix metalloproteinase 9 (MMP9), PDGFA, and PDGFB (93). The gene discussed is GP6; the disease is acute respiratory distress syndrome.
