Data providing direct evidence for a causative link between endothelial dysfunction, microvascular disease and diabetic end-organ damage are scarce. Here we show that activated protein C (APC) formation, which is regulated by endothelial thrombomodulin, is reduced in diabetic mice and causally linked to nephropathy. Thrombomodulin-dependent APC formation(More)
Renal sympathetic denervation (RDN) is a novel treatment option in patients with treatment-resistant arterial hypertension. A subset of recently published randomized and non-randomized trials indicates that RDN leads to sustained lowering of blood pressure (BP) under controlled study conditions. However, registry data that allow evaluation of safety and(More)
Atherosclerosis is a chronic inflammatory disease. Lesion progression is primarily mediated by cells of the monocyte/macrophage lineage. IL-17A is a proinflammatory cytokine, which modulates immune cell trafficking and is involved inflammation in (auto)immune and infectious diseases. But the role of IL-17A still remains controversial. In the current study,(More)
OBJECTIVE Inflammatory mechanisms are involved in atherosclerotic plaque rupture and subsequent thrombin formation. Thrombin not only plays a central role in thrombus formation and platelet activation, but also in the induction of inflammatory processes. We assessed the hypothesis that melagatran, a direct thrombin inhibitor, attenuates plaque progression(More)
Considerable evidence of an association between Chlamydia pneumoniae infections and cardiovascular disease has emerged. Animal models using genetically altered mice and hypercholesterolemic rabbits have shown a pathogenic role of C. pneumoniae in accelerating atherosclerotic plaque development. In the present study, we evaluated the effect of chronic C.(More)
BACKGROUND Drug-coated balloon angioplasty (DCBA) was shown to be superior to standard balloon angioplasty (POBA) in terms of restenosis prevention for de novo superficial femoral artery disease. For in-stent restenosis, the benefit of DCBA over POBA remains uncertain. METHODS AND RESULTS One hundred nineteen patients with superficial femoral artery(More)
Proteoglycans are important constituents of blood vessels and accumulate in various forms of vascular disease. Little is known concerning the proteoglycan composition of restenotic lesions formed after angioplasty and whether the proteoglycan composition of these lesions differs from that of primary atherosclerosis. Accordingly, we sought to characterize(More)
INTRODUCTION The Chinese extract Rhizoma coptidis is well known for its anti-inflammatory, antioxidative, antiviral, and antimicrobial activity. The exact mechanisms of action are not fully understood. METHODS We examined the effect of the extract and its main compound, berberine, on LPS-induced inflammatory activity in a murine macrophage cell line. RAW(More)
Atherosclerosis is considered to be an inflammatory disease. Tissue factor (TF), a prothrombotic molecule expressed by various cell types within atherosclerotic plaques, is thought to play an essential role in thrombus formation after atherosclerotic plaque rupture. Recent studies suggest that the antiinflammatory cytokine interleukin-10 (IL-10) has many(More)
Clinical studies have demonstrated that the inhibition of the renin-angiotensin system (RAS) by either an angiotensin-converting enzyme (ACE)-inhibitor or an angiotensin II receptor type 1 (AT(1))-antagonist reduces cardiovascular disease. The objective of this study was to evaluate underlying mechanisms of the AT(1)-antagonist telmisartan in comparison to(More)
