  1. 6. The Impact of Pancreatic Islet Vascular Heterogeneity on Beta Cell Function and Disease

    Författare :Sara Ullsten; Per-Ola Carlsson; Joey Lau; Sara Bohman; Rebecca L. Hull; Uppsala universitet; []
    Nyckelord :Pancreatic islets; heterogeneity; islet vascularity; blood flow; islet transplantation; islet amyloid; insulitis; type 1 diabetes; beta cell proliferation; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Diabetes Mellitus is a group of complex and heterogeneous metabolic disorders characterized by hyperglycemia. Even though the condition has been extensively studied, its causes and complex pathologies are still not fully understood. The occurring damage to the pancreatic islets is strikingly heterogeneous.

  3. 7. Neogenesis and alloxan toxicity in pancreatic islets, with special reference to the transplanted human β-cell

    Författare :Björn Tyrberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Alloxan; β-cell; diabetes; differentiation; growth; insulin secretion; nephrectomy; ob ob; pancreatic islet; transplantation; guinea-pig human; mouse; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : The aim of this work was to study whether adult human pancreatic β-cells have the capacity to proliferate in culture and after transplantation to the renal subcapsular space of mice. An immunosuppressive regimen for human islet discordant xenotransplantation to mice was designed. LÄS MER

  4. 8. Leukocytes in Angiogenesis : Learning from Transplanted Pancreatic Islets

    Författare :Gustaf Christoffersson; Mia Phillipson; Kristian Pietras; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiogenesis; pancreatic islet transplantation; islets of Langerhans; diabetes mellitus; leukocytes; neutrophils; macrophages; pericytes; MMP-9; VEGF-A; Medical Science; Medicinsk vetenskap;

    Sammanfattning : Angiogenesis, the growth of new blood vessels, is a complex process involving several cell types and molecular signals. Excessive vascular growth is a problem in tumors, and insufficient vascularization hampers the function of transplanted insulin-producing pancreatic islets. LÄS MER

  5. 9. Studies of Regulatory T cells with Implications for Clinical Applications

    Författare :Marcus Bergström; Olle Korsgren; Wayne Hawthorn; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Regulatory T cell; Treg; Transplantation; Immunology; Tolerance; Islet transplantation; Immunosuppression; Immunologi; Immunology;

    Sammanfattning : Regulatory T cells (Tregs) are vital for regulating immune homeostasis and for preventing immunopathology. The immunosuppressive functions of Tregs have raised hope for their potential use in clinical applications. LÄS MER

  7. 10. Experimental Studies Aiming to Prevent Type 1 Diabetes Mellitus

    Författare :Tobias Rydgren; Stellan Sandler; Nils Welsh; Adrian Bone; Uppsala universitet; []
    Nyckelord :Cell biology; Diabetes; Interleukin-1 trap; Simvastatin; Nitric oxide synthase; Cytokine; Pancreatic islet; Streptozotocin; Transplantation; Cellbiologi;

    Sammanfattning : Type 1 diabetes mellitus (T1DM) is an autoimmune disease in which T-cells and macrophages invade the islets of Langerhans and selectively destroy the insulin producing β-cells, either directly or through the secretion of e.g. cytokines and nitric oxide (NO). This thesis has studied possible strategies to prevent T1DM. LÄS MER
