  1. 1. Studies of sulfatide expression in relation to beta cell function

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

    Sammanfattning : 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. LÄS MER

  3. 2. Maf transcription factors in beta cell function

    Författare :Elvira Ganic; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Beta cell; MafA; type 2 diabetes; insulin secretion; transcription; monoamine oxidase; MaoA; MaoB; nicotinic receptor subunits; nAChRs;

    Sammanfattning : Diabetes mellitus is metabolic disorder caused by a defect or lack of beta cell-produced insulin that controls blood glucose homeostasis. In addition to glucose, insulin secretion is regulated by the autonomic nervous system (ANS); the neurotransmitter acetylcholine as well as monoamines, such as dopamine, serotonin, melatonin and norepinephrine.

  4. 3. PET imaging of beta-cell mass

    Författare :Pierre Cheung; Olof Eriksson; Weibo Cai; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET imaging; diabetes; beta-cell mass; affibody; SC-islets; Medicinal Chemistry; Läkemedelskemi;

    Sammanfattning : A hallmark of diabetes is the progressive loss of the beta-cell mass (BCM) and function. Most of the diagnostic methods for diabetes are mostly reflective of the beta-cell function, whereas current methodologies for studying the beta-cell mass are limited to post-mortem biopsies or highly invasive methods.

  5. 4. Beta Cell Function: from Human Genetics to Animal Models

    Författare :Martins Kalis; Diabetes - immunovirologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; animal model; Dicer1; genetics; genetic association; single nucleotide polymorphism; SNP; INS-1E; AAT; FOXP3; beta cell function; insulin secretion; FFAR1; insulin; T2D; glucose; T1D;

    Sammanfattning : Beta cell function is an important factor in the development of both Type 1 (T1D) and Type 2 (T2D) diabetes mellitus. T1D is characterized by a primary defect in insulin secretion due to the immune-mediated beta cell destruction, however, the more common T2D beside insulin resistance also include impaired beta cell function as a consequence to abnormal glucose homeostasis.

  7. 5. Autoantibodies as markers of beta-cell autoimmunity in children

    Författare :Hanna Holmberg; Johnny Ludvigsson; Mona Landin-Olsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type 1 diabetes; Autoantibodies; Beta-cell autoimmunity; Children; Breast-feeding; HLA haplotypes; Insulin gene; Paediatric medicine; Pediatrisk medicin;

    Sammanfattning : Type 1 diabetes (T1D) is a chronic disease caused by destruction of the insulin producing beta-cells in the pancreas. The incidence of T1D has increased rapidly, especially in the Western world and among young children. LÄS MER
