16. ADP regulation of insulin secretion and beta-cell apoptosis
Sammanfattning : The aims of this dissertation were to investigate the effects of extracellular purines on insulin secretion, and apoptosis in mouse pancreatic islets and β-cells; to examine if high glucose and free fatty acids induces β-cell apoptosis via autocrine effects of ADP acting on the P2Y13 receptor; and to investigate the modulation of extracellular purines in vascular smooth muscle cells (VSMCs) through ectonucleotidase or ATP release under the effect of high glucose. The expression of the ADP receptors P2Y1 and P2Y13 were shown in both mouse pancreatic islets and isolated β-cells using real-time PCR quantification. LÄS MER
17. Non-coding RNA-based therapeutics and biomarkers for treatment and detection of vascular disease
Sammanfattning : Cardiovascular disease (CVD), with atherosclerosis as its main underlying pathology, is the most prominent cause of death worldwide. Progression and rupture of atherosclerotic plaques lead to potential adverse pathological events such as myocardial infarction and stroke. LÄS MER
18. Phenotypic modulation of vascular smooth muscle in organ culture
Sammanfattning : Contraction of blood vessels for the regulation of blood flow and pressure is dependent on vascular smooth muscle cells (VSMC) located in the medial layer of the vascular wall. Adult, differentiated VSMC have a well developed contractile system and a low rate of proliferation. LÄS MER
19. Macro- and microvascular complications of diabetes: Studies on NFAT (Nuclear Factor of Activated T-cells) as a novel target for the treatment of atherosclerosis and vascular dysfunction in diabetes
Sammanfattning : Diabetes is associated with devastating chronic complications including coronary heart disease and stroke (macrovascular complications) as well as microvascular disorders leading to damage of the small vessels and the development of retinopathy, nephropathy and neuropathy. The underlying pathogenesis is not clear, but hyperglycemia has been identified as an important risk factor. LÄS MER
20. Action and interaction of growth factors and regulatory molecules in vascular cells : With special reference to the IGF-I-system
Sammanfattning : Vascular function is greatly influenced by growth factors and regulatory molecules that can interact with each other in a complex pattern in the vascular wall. In this thesis we studied how different substances of special interest in the pathogenesis of vascular disease interact and regulate each other's expressions in endothelial cells and vascular smooth muscle cells (VSMCs).
