  1. 1. Epac2 signaling at the β-cell plasma membrane

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ida Alenkvist; Anders Tengholm; Olga Göransson; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; β-cell; insulin secretion; cAMP; Ca2 ; Epac; Rap; exocytosis; sulfonylurea; Medical Cell Biology; Medicinsk cellbiologi;

    Abstract : Secretion of appropriate amounts of insulin from pancreatic β-cells is crucial for glucose homeostasis. The β-cells release insulin in response to glucose and other nutrients, hormones and neurotransmitters, which trigger intracellular signaling cascades, that result in exocytotic fusion of insulin-containing vesicles with the plasma membrane.

  2. 2. Diabetes in Young Adults Remission, β-cell function and markers of inflammation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna Schölin; Elisabeth Björk; Anders Karlsson; Jan Åman; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Internal medicine; type 1 diabetes; young adults; remission; β-cell function; islet antibodies; gender; CRP; Invärtesmedicin; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Internal medicine; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Invärtesmedicin; Internal Medicine; invärtesmedicin;

    Abstract : Type 1 diabetes is caused by immuno-mediated β-cell destruction leading to insulin deficiency and hyperglycaemia. The decline in β-cell function and the clinical course after diagnosis vary. Whether the process of destruction of the β-cells is associated with markers of a non-specific inflammatory response is unknown. READ MORE

  3. 3. Search for molecular and metabolic mechanisms contributing to impaired β-cell function

    University dissertation from Units of Epigenetics and Diabetes and Molecular Metabolism, Department of Clinical Sciences, Malmö

    Author : Siri Malmgren; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HIF-1α; oxygen consumption; β-cell; Insulin secretion; Type 2 Diabetes; mitochondrial metabolism; metabolic profiling; Lipotoxicity; Histone acetylation; Histone methylation;

    Abstract : Type 2 Diabetes (T2D) prevalence is growing to pandemic proportions worldwide. The link between genotype, environment and β-cell function is still being investigated. READ MORE

  4. 4. β-cell dysfunction in Huntington's disease

    University dissertation from Department of Clinical Sciences, Lund University

    Author : Karl Bacos; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; metabolism; secretion; Insulin; trafficking; R6 2 mouse; granule; exocytosis; neurodegeneration; huntingtin;

    Abstract : Huntington's disease (HD), a fatal neurodegenerative disorder, is associated with an increased risk of diabetes mellitus. The reason for this is unknown, but considering the functional similarities of neurons and the insulin secreting pancreatic β-cell, pathological mechanisms may be shared by both cell types and account for neuronal as well as endocrine dysfunction.

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Björn Tyrberg; [1999]
    Keywords : 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; MEDICINE Morphology; cell biology; pathology Cell biology; MEDICIN Morfologi; cellbiologi; patologi Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : 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. READ MORE
