  2. 21. Exploration of Conditions Affecting Cytokine Production in Experimental Type 1 Diabetes Mellitus

    Author : Lina Thorvaldson; Stellan Sandler; Michael Welsh; Maria Holstad; Maria Faresjö; Uppsala universitet; []
    Keywords : Cell biology; Cytokine; Diabetes; Tumor necrosis factor-α; Interferon-γ; Interleukin-4; Interleukin-10; Transplantation; Pancreatic islet; Glucose; Regulatory T cell; Cellbiologi;

    Abstract : Cytokines are soluble signalling mediators within the immune system, and have been shown to be of importance in the development of type 1 diabetes (T1D). This thesis studied the production of cytokines in experimental models of T1D and during transplantation of insulin-producing islets of Langerhans. READ MORE

  4. 22. ADP regulation of insulin secretion and beta-cell apoptosis

    Author : Chanyuan Tan; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; P2Y; β-cell; ADP; insulin; apoptosis; autocrine; ectonucleotidase;

    Abstract : 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. READ MORE

  5. 23. Protein expression analysis of insulin producing cells exposed to endoplasmic reticulum stress

    Author : Victoria Rosengren; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The prevalence of type 2 diabetes mellitus (T2DM) is increasing rapidly as a result of the obesity epidemic. T2DM develops in individuals who fails to compensate for increased demand of insulin. READ MORE

  6. 24. Pharmaceutical Protection of Beta-Cells in Diabetes : Using Tyrosine Kinase Inhibition and NOX4 Inhibitors

    Author : Andris Elksnis; Per-Ola Carlsson; Nils Welsh; Sergiu-Bogdan Catrina; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diabetes mellitus; Tyrosine kinase inhibitors; Imatinib; AMPK; Oxidative stress; NADPH-oxidase; NOX; NOX4; Medical Cell Biology; Medicinsk cellbiologi;

    Abstract : Diabetes mellitus is a complex and heterogenous disease, with loss of beta-cell function and mass being a characteristic of not only type 1 diabetes (T1D), but also type 2 diabetes (T2D). In T1D, inappropriate inflammatory signaling is thought to participate in the autoimmune suppression and destruction of beta-cells. READ MORE

  7. 25. Perilipin expression in the islets of Langerhans and Surface expression in the baculovirus/insect cell system

    Author : Jörgen Borg; Molekylär endokrinologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biology; Biologi; lipotoxicity; beta-cell; perilipin; amino-terminal anchor; Baculovirus; surface display;

    Abstract : Surface display in insect cells: Systems available for surface display that utilize bacterial phages are insufficient for displaying a number of eukaryotic proteins. By instead presenting proteins on the surface of eukaryotic cells or virus, some of these problems might be overcome. READ MORE
