  1. 16. Biological consequences of endothelial cell signaling

    Författare :Ross Smith; Lena Claesson-Welsh; Przemyslaw Sapieha; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; VEGFR2; Mechanosensing; Retinopathy; Biologi; Biology;

    Sammanfattning : Endothelial cells make up the inner lining of blood and lymphatic vessels, where they participate in functions vital to survival of the tissue; endothelial cells maintain vessel integrity, dynamically respond to the changing metabolic needs of tissues, and participate in many tissue-specific functions. Endothelial cells sense environmental cues which initiate signal transduction pathways that regulate behavior. LÄS MER

  3. 17. DNA methylation in T cell leukaemia

    Författare :Maike Bensberg; Colm Nestor; Maria Jenmalm; Sofie Degerman; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : T cell acute lymphoblastic leukaemia (T-ALL) is a predominantly paediatric cancer that stems from malignant transformation of developing T cells. While the disease has an overall survival rate of 80%, the intense chemotherapy treatment causes severe toxicity and long-term side effects. LÄS MER

  4. 18. Studies of individual pancreatic -cells : Electrophysiological analysis of rhythmic behaviour and development of new techniques

    Författare :Staffan Dryselius; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Diabetes; pancreatic beta-cells; insulin release; signal transduction; cytoplasmic calcium; oscillations; patch clamp; ATP-regulated potassium channels; voltage-dependent calcium channels; metabolism; calcium ion; strontium ion; manganese ion; wavelets; de-noising; pattern recognition; superfusion; solution changes; microscopic labelling; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : The insulin concentration in blood varies periodically, which is believed to prevent down-regulation of the hormone receptors. Loss of the regular insulin oscillations is considered to be an early sign of developing diabetes. LÄS MER

  5. 19. Islet insulin secretory patterns in diabetes and the role of UCP2

    Författare :Jian-Man Lin; Valdemar Grill; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; type 1 diabetes; type 2 diabetes; NOD; GK; congenes; KKAy; human; islet; glucose; insulin release; oscillation; frequency; amplitude; oxidation; respiration; UCP2; western blot; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : During development of type 1 and type 2 diabetes plasma insulin patterns are altered. Since the islet insulin release pattern has been implicated in this development, insulin secretion from single islets was studied and linked to the islet protein levels of uncoupling protein-2 (UCP2).

  7. 20. Challenges in Islet Transplantation and Strategies to Improve Beta-Cell Function

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

    Sammanfattning : 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. LÄS MER
