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

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

    Sammanfattning : 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. LÄS MER

  3. 17. Developmental role and ligand binding properties of macrophage scavenger receptor MARCO

    Författare :Yunying Chen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Macrophages express several cell surface receptors, that mediate the recognition of a wide range of endogenous and exogenous ligands. In this manner, macrophages are able to perform their multiple biological functions in regulation of homeostasis and host defense. LÄS MER

  4. 18. Defining the role of CD47 and SIRPα in murine B cell homeostasis

    Författare :Shrikant S Kolan; Per-Arne Oldenborg; Mikael Karlsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; B cells; CD47; SIRPα; Follicular B cell; Marginal zone macrophages; immunologi; Immunology;

    Sammanfattning : B cell development is a highly organized process, which commences in the fetal liver during embryogenesis and in the bone marrow (BM) after birth. Surface IgM+ immature B cells emigrate from the BM via the blood stream to the spleen and finally differentiate into conventional mature follicular B (FoB) cells and marginal zone (MZ) B cells.

  5. 19. Autoimmune Regulator Deficient Mice, an Animal Model of Autoimmune Polyendocrine Syndrome Type I

    Författare :Signe Hässler; Ola Winqvist; Olle Kämpe; Bertrand Huard; Uppsala universitet; []
    Nyckelord :Molecular medicine; autoimmune regulator; autoimmune polyendocrine syndrome type I; peripheral tolerance; antigen presenting cells; autoimmunity; danger signal; knockout mice; Molekylärmedicin;

    Sammanfattning : Autoimmune diseases develop when the immune system fails to distinguish self from non-self or when the immune system is hypersensitive to endogenous or exogenous danger signals, or when a tissue erroneously sends a danger signal to the immune system. The education of the immune system to distinguish self from non-self is mainly carried out in the thymus and gives rise to central tolerance, whereas the ability to sense a danger or a healthy tissue constitutes peripheral tolerance.

  7. 20. Targeted radionuclide therapy for patients with neuroendocrine tumours with focus on normal tissue response in 177-Lu-DOTATATE treatment

    Författare :Johanna Svensson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radionuclide therapy; Neuroendocrine tumours; 177Lu-DOTATATE; dosimetry; normal tissue response;

    Sammanfattning : Targeted radionuclide therapy with 177Lu-DOTATATE for patients with neuroendocrine tumours utilises the frequent overexpressing of somatostatin receptors on the tumour cells. This treatment modality has demonstrated valuable patient benefits and is well tolerated. However, renal and bone marrow toxicity can become dose limiting and persisting. LÄS MER
