1. 1. Islet xenotransplantation : An immunological study in the pig-to-mouse model

   Författare :Birgitta Benda; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; xenotransplantation; porcine; islet; in vivo; knock-out mouse; immunohistochemistry; CsA; MDL 201; 449A; Ig; FcR; IL-6; perforin; granzyme B; macrophage; eosinophilic granulocyte; T cell; TCR; IFN- g; TNF- a; IL-2; Onkologi; Oncology; Onkologi; Clinical Immunology; klinisk immunologi;

   Sammanfattning : Successful clinical xenotransplantation, i.e., transplantation between species, would eliminate the shortage of donor organs. In order to study the acute cellular rejection reaction following discordant xenogeneic transplantation, an experimental pig-to- mouse islet xenotransplantation model was established. LÄS MER

3. 2. Pancreatic Islet Transplantation : Modifications of Islet Properties to Improve Graft Survival

   Författare :Sanja Cabric; Olle Korsgren; Bo Nilsson; Peetra Magnusson; Michael Breimer; Uppsala universitet; []
   Nyckelord :Medicine; Diabetes; islet transplantation; islets of Langerhans; coagulation activation; IBMIR; hirudin; heparin; growth factor; angiogenesis; Medicin;

   Sammanfattning : During the past decade clinical islet transplantation has become a viable strategy for curing type 1 diabetes. The limited supply of organs, together with the requirement for islets from multiple donors to achieve insulin independence, has greatly limited the application of this approach. LÄS MER

4. 3. Islet Xenotransplantation : An Experimental Study of Barriers to Clinical Transplantation

   Författare :Peter Schmidt; Olle Korsgren; Bo Nilsson; Karin Ulrichs; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; xenotransplantation; islets of Langerhans; rejection; diabetes; porcine endogenous retroviruses; quantitative RT-PCR; cytokines; animal models; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

   Sammanfattning : In the field of transplantation, the increasing deficit of human donors have lead to an interest in animals as an alternative source of organs and tissues. Different in vitro systems and rodent models of xenotransplantation were used to examine the most significant barriers that have to be overcome, before isolated islets of Langerhans from pigs can be used as a cure for insulin-dependent diabetes mellitus in humans.

5. 4. Disturbed Islet Function and Alterations in Islet Protein Expression

   Författare :Henrik Ortsäter; Peter Bergsten; Franz Schuit; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell biology; islet; glucose; oleate; corticosterone; oxygen tension; insulin release; protein profiling; Clark-like electrodes; SELDI-TOF MS; PPI-B; 11β-HSD1; Cellbiologi; Cell biology; Cellbiologi;

   Sammanfattning : Pancreatic β-cells sense the concentration of glucose in the systemic circulation through metabolism of the sugar molecule. Failure to correlate the blood sugar concentration to an appropriate metabolic signal disrupts the function of the β-cell as a controller of glucose homeostasis and may contribute to the development of type 2 diabetes mellitus.

7. 5. Influence of Islet-derived Factors in Islet Microcirculation and Endocrine Function

   Författare :Carl Johan Drott; Per-Ola Carlsson; Leif Jansson; Albert Salehi; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetes mellitus; pancreas; blood flow; islet vascularity; islet-derived; TSP-1; ghrelin; CART; irisin; Medical Cell Biology; Medicinsk cellbiologi;

   Sammanfattning : Diabetes mellitus is a disorder with complex pathology and is frequently associated with vascular complications. In the islet micro milieu locally generated factors may affect both the physiology and the morphology of the tissue. LÄS MER
