Diabetes mellitus is associated with cognitive impairment which may convert to vascular or neurodegenerative dementia. Impairment of cognitive functions affects patients with type 1 and especially type 2 diabetes, with a number of vascular, metabolic and psychosocial factors involved in its development. As hyperglycemia and hypoglycemia also play an important role, important is the correct strategy of diabetes therapy which utilizes a combination of metformin with modern safe antidiabetics (incretin drugs, gliflozins, insulin analogues)...

The endothelial lining of blood vessels is severely affected in type II diabetes. Yet, there is still a paucity on the use of diabetic endothelial cells for study and assessment of implantable devices targeting vascular disease. This critically impairs our ability to determine appropriate topographical cues to be included in implantable devices that can be used to maintain or improve endothelial cell function in vivo. Here, the functional responses of healthy and diabetic human coronary arterial endothelial cells were studied and observed to differ depending on topography...

BACKGROUND: Microvesicles (MVs) are small membrane vesicles that are derived from many different cell types by a process of exocytic budding of the plasma membrane. MVs may be associated with a higher incidence of vascular disease in diabetic patients, but the mechanism of this association is unclear. Diabetic patients also show hypercoagulability and platelet hyperaggregability. In this study, we investigated the generation and activity of high glucose (HG)-induced MVs from monocytes to elucidate the potential mechanism of such MVs in diabetes...

Diabetic nephropathy is a major microvascular complication of diabetes mellitus, and the leading cause of end stage renal disease worldwide. The pathogenesis of diabetic nephropathy is complex, making the development of novel treatments that stop or reverse the progression of microalbuminuria into end stage renal disease a challenge. Protease activated receptor (PAR)-2 has recently been shown to aggravate disease progression in diabetic nephropathy based upon which it was suggested that PAR-2 would be a potential target for the treatment of diabetic nephropathy...

OBJECTIVE: To determine whether biomarkers of inflammation and endothelial dysfunction are associated with the development of kidney dysfunction and the time frame of their association. RESEARCH DESIGN AND METHODS: Biomarkers were measured at four time points during 28 years of treatment and follow-up in patients with type 1 diabetes in the DCCT/EDIC cohort. In addition to traditional biomarkers of inflammation (C-reactive protein and fibrinogen), we measured interleukin-6 (IL-6) and soluble tumor necrosis factor receptors 1 and 2 (sTNFR-1/2), markers of endothelial dysfunction (soluble intracellular adhesion molecule-1, vascular cell adhesion molecule-1, and E-selectin [sE-selectin]), and fibrinolysis (total and active plasminogen activator inhibitor-1 [PAI-1])...

Silent information regulator family protein 1 (Sirt1) has recently gained attention for its protective effects against diabetic and cardiovascular diseases (CVDs). Vascular smooth muscle endothelin type B (ETB) receptors are involved in the pathogenesis of CVDs and diabetes. The aim of present study was to explore whether Sirt1 is involved in high glucose (HG)-mediated regulation of ETB receptors in rat superior mesenteric arteries (SMA). The rat SMA segments were cultured in the presence and absence of HG with or without the activator of Sirt1 and specific inhibitor for the extracellular signal-regulated protein kinase 1/2 (ERK1/2) for 24 h...

Peripheral arterial disease (PAD) is a debilitating complication of diabetes mellitus (DM) that leads to thousands of injuries, amputations, and deaths each year. The use of mesenchymal stem cells (MSCs) as a regenerative therapy holds the promise of regrowing injured vasculature, helping DM patients live healthier and longer lives. We report the use of muscle-derived MSCs to treat surgically-induced hindlimb ischemia in a mouse model of type 1 diabetes (DM-1). We serially evaluate several facets of the recovery process, including αVβ3 -integrin expression (a marker of angiogenesis), blood perfusion, and muscle function...

In patients with acute atherothrombotic disease, diabetes or glucose intolerance is frequently found. Indeed, the number of people with diabetes in the world continues to increase and is expected to reach more than 500 million people by 2035. Diabetes is a pathology commonly associated with both microvascular and macrovascular complications. Although the mortality of coronary artery disease has decreased significantly over the past 20 years, mortality in patients with type 2 diabetes has changed little and atherothrombotic events remain the leading cause of death in diabetic patients...

AIMS/HYPOTHESIS: Vascular inflammation and endothelial dysfunction are thought to contribute to arterial stiffening and hypertension. This study aims to test this hypothesis with longitudinal data in the context of type 1 diabetes. METHODS: We investigated, in an inception cohort of 277 individuals with type 1 diabetes, the course, tracking and temporal inter-relationships of BP, specifically pulse pressure (a marker of arterial stiffening) and hypertension, and the following biomarkers of systemic and vascular inflammation/endothelial dysfunction: C-reactive protein (CRP), soluble intracellular adhesion molecule-1 (sICAM-1), soluble vascular cellular adhesion molecule-1 (sVCAM-1) and soluble E-selectin (sE-selectin)...

The activation of NLR family pyrin domain containing 3 (NLRP3) inflammasome have been implicated in the initiation or progression of atherosclerosis. Recent research showed that irisin, a newly discovered adipomiokine, alleviates endothelial dysfunction in type 2 diabetes partially via reducing oxidative/nitrative stresses, suggesting that irisin may be a promising candidate for the treatment of vascular complications of diabetes. However, the association between irisin and NLRP3 inflammasome in the pathogenesis of atherosclerosis remains unclear...
