OBJECTIVES It is believed that adipose tissue acts as an endocrine organ by producing inflammatory mediators and thereby contributes to the increased cardiovascular risk seen in obesity. A link between adipose tissue mass and angiogenesis has been suggested. Vascular endothelial growth factor (VEGF) seems to be implicated in this process. Members of the(More)
Angiogenesis is a common feature observed in advanced atherosclerotic lesions. We hypothesized that oxidized phospholipids (OxPLs), which accumulate in atherosclerotic vessels can stimulate angiogenesis. We found that oxidized 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphocholine (OxPAPC) stimulated the formation of sprouts from endothelial cell spheroids(More)
OBJECTIVE Lipoprotein-derived phospholipid oxidation products have been implicated as candidate triggers of the inflammatory process in atherosclerosis. However, in vivo evidence regarding the impact of oxidized phospholipids on the artery wall thus far has been elusive. Therefore, the aim of this study was to investigate if structurally defined oxidized(More)
OBJECTIVES Members of the glycoprotein 130 (gp130) receptor-gp130 ligand family play a role in angiogenesis in different tissues. We tested the effect of this cytokine family on the angiopoietin (Ang)-Tie system, which is involved in blood vessel maturation, stabilization, and regression. RESULTS Oncostatin M (OSM) increased Ang2 expression in human(More)
Plaque destabilization leading to myocardial infarction is observed after surgery even if the intervention is of noncardiovascular nature. Mediators of peri- or postoperative stress responsible for such events could include catecholamines and lipopolysaccharide (LPS). Monocytes may be involved in destabilization of atherosclerotic plaques by production of(More)
Increasing evidence points to the role of oxidized phospholipids as modulators of inflammatory processes. These modified phospholipids are derived from lipoproteins or cellular membranes and accumulate at sites of inflammation such as atherosclerotic lesions. It has been shown that oxidized phospholipids influence a variety of cellular functions such as(More)
Stromal derived factor 1 (SDF-1) is a CXC chemokine important in the homing process of stem cells to injured tissue. It has been implicated in healing and tissue repair. Growing evidence suggests that the glycoprotein-130 (gp130) ligand family is involved in repair processes in the heart. The aim of our study was to determine whether gp130 ligands could(More)
