  1. 6. Prevention of beta-cell dysfunction via targeting novel GPCRs in pancreatic islets

    Författare :Rajesh Kumar; Islet cell physiology; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type II Diabetes; GPCR; Pancreatic islets; Estrogen; Alpha-1 antitrypsin.;

    Sammanfattning : The primary aim of this thesis was to investigate the role of G protein coupled receptors (GPCRs) in insulin secretion and beta-cell survival. The second aim was to determine which pathway is involved in insulin release and beta-cell protection via GPCRs. LÄS MER

  3. 7. Control of metabolism and hormone secretion from pancreatic alpha and beta cells

    Författare :Jelena Stamenkovic; Diabetes - molekylär metabolism; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CLOCK genes; insulin; glucagon; metabolites; mitochondria; knock out;

    Sammanfattning : Type 2 Diabetes (T2D) is a multifactorial disease, which has made it difficult to resolve its pathophysiology. We investigated processes that could contribute to the development of T2D. LÄS MER

  4. 8. Regulation of exocytosis by Ca2+ and cAMP - A study on pancreatic beta- and alpha-cells

    Författare :Xiaosong Ma; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Endocrinology; secreting systems; type-2 diabetes; SUR1; Ca2 -channel; glucagon; exocytosis; insulin; diabetology; Endokrinologi; sekretion; diabetologi;

    Sammanfattning : Type-2 diabetes is characterized by impaired insulin secretion associated with excess glucagon release. Exocytosis of insulin- or glucagon-containing granules is initiated by Ca2+-influx through voltage-dependent Ca2+-channels and is modulated by the second messengers such as cAMP. LÄS MER

  5. 9. Study of DNA methylation in human pancreatic islets

    Författare :Elin Hall; Diabetes - epigenetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; type 2 diabetes; epigenetics; DNA mehtylation; human pancreatic islets; insulin secretion;

    Sammanfattning : Today type 2 diabetes is a common disease with a worldwide prevalence of 8.3%. The disease is characterised by hyperglycaemia which is a result of insufficient insulin secretion from the beta-cells in the pancreatic islets as well as an insulin resistance seen in the target tissues.

  7. 10. Islet Amyloid Polypeptide: Interaction with Amyloid Beta, Alpha-Synuclein and BRICHOS

    Författare :Ye Wang; Gunilla Westermark; Ludmilla Morozova-Roche; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amyloid; IAPP; Abeta; alpha-synuclein; Bri2 BRICHOS; luminescent conjugated oligothiophenes; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning :  Amyloid, the congophilic deposits of misfolded protein, are pathological hallmarks of many common diseases, among others, Alzheimer’s disease (AD), Parkinson’s disease (PD), and type 2 diabetes (T2D). Amyloid beta (Aβ) forms senile plaques in AD, alpha-synuclein (aSyn) forms Lewy bodies and Lewy neurites in PD, islet amyloid polypeptide (IAPP) forms islet amyloid in T2D. LÄS MER
