  2. 6. Challenges in Islet Transplantation and Strategies to Improve Beta-Cell Function

    Author : Hanna Liljebäck; Per-Ola Carlsson; James Shaw; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Islet transplantation; Type 1 diabetes; Mesenchymal stem cells; Medical Cell Biology; Medicinsk cellbiologi;

    Abstract : The incidence of type 1 diabetes is increasing worldwide and therapies of islet transplantation and potential cell-based therapies are rapidly evolving. Choosing the optimal site for such therapies is crucial for safety and for obtaining the best possible outcome. READ MORE

  4. 7. Studies of sulfatide expression in relation to beta cell function

    Author : Maria K. Blomqvist; Göteborgs universitet; []
    Keywords : sulfatide; glycosphingolipid; insulin; beta cell; diabetes mellitus; animal models; ; beta cell line;

    Abstract : Previous studies have shown that the glycosphingolipid sulfatide (3´-sulfogalactosyl-ceramide) is present and functionally involved in pancreatic beta cells. In these cells, sulfatide is synthesised as two major isoforms, C16:0 and C24:0 sulfatide, with different length of the fatty acid chain of the ceramide moiety. READ MORE

  5. 8. Engraftment of Pancreatic Islets in Alternative Transplantation Sites and the Feasibility of in vivo Monitoring of Native and Transplanted Beta-Cell Mass

    Author : Daniel Espes; Per-Ola Carlsson; Joey Lau; Mia Phillipson; Eelco de Koning; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type 1 diabetes; Islet transplantation; Alternative implantation sites; Exendin-4; Positron Emission Tomography; 5-hydroxy tryptophan; Beta-cell mass; Medical Cell Biology; Medicinsk cellbiologi;

    Abstract : Islet transplantation is a possible curative treatment for type 1 diabetes (T1D). Currently the liver dominates as implantation site, despite the many challenges encountered at this site.Acute hypoxia in islets transplanted to muscle and omentum, two possible alternative sites, was prevailing.

  6. 9. Heparan sulfate dependent cell signaling and associated pathophysiology : Implications in tumorigenesis and embryogenesis

    Author : Tahira Batool; Jin-Ping Li; Aristidis Moustakas; Liliana Schaefer; Ingvar Ferby; Michael Welsh; Anders Malmström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heparanase; Glucuronyl-C5 epimerase; Heparan Sulfate; Heparin; Lung Cancer; Cancer cell Singling; TGF-Beta; BMP; VEGF; Notch Signaling; Tumor growth; Metastasis; embryonic development; Medical Biochemistry; Medicinsk biokemi;

    Abstract : Heparan sulfate proteoglycans (HSPGs) consist of a protein core to which several linear, negatively charged heparan sulfate (HS) chains are covalently attached. HSPGs are expressed on the cell surface and in the extra-cellular matrix (ECM) where they have diverse biological functions, for example co-receptor functions. READ MORE

  7. 10. Maf and Mitf transcription factors regulate pancreatic endocrine cell differentiation and function

    Author : Magdalena Mazur; Stamcellscentrum (SCC); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pancreas development; beta cells; insulin; MafA; MafB; Mitf; diabetes;

    Abstract : Diabetes - the imbalance in glucose homeostasis is partially caused by loss or dysfunction of pancreatic insulin producing β cells or development of insulin resistance. In Type 1 diabetes β cells are destroyed in the process of an autoimmune attack, whereas in Type 2 diabetes, islets produce insufficient amounts of insulin or the insulin cannot be used adequately.
