  1. 1. Enterovirus Infections of β-Cells : A Mechanism of Induction of Type 1 Diabetes?

    Författare :Anna-Karin Berg; Gun Frisk; Torsten Tuvemo; Arne Andersson; Merja Roivainen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; enterovirus; type 1 diabetes; β-cells; human pancreatic islets; picornavirus; chemokines; nitric oxide; Pediatrik; Paediatric medicine; Pediatrisk medicin;

    Sammanfattning : The process of β-cell destruction that leads to type 1 diabetes (T1D) is incompletely understood and it is believed to be a result of both genetic and environmental factors. Enterovirus (EV) infections of the β-cells have been proposed to be involved, however, the effects of EV infections on human β-cells have been little investigated. LÄS MER

  3. 2. Oscillatory Ca2+ signaling in glucose-stimulated murine pancreatic β-cells : Modulation by amino acids, glucagon, caffeine and ryanodine

    Författare :Meftun Ahmed; Per Lindström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; pancreatic β-cells; islets of Langerhans; glucose; Ca2 oscillations; Ca2 transients; potassium; ryanodine; caffeine; glucagon; cAMP; inositol 1; 4; 5-trisphosphate; fura-2; glycine; alanine; arginine; Ca2 channels; rats; lean mice; ob ob mice; leptin; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : Oscillations in cytoplasmic Ca2+ concentration ([Ca2+]i) is the key signal in glucose-stimulated β-cells governing pulsatile insulin release. The glucose response of mouse β-cells is often manifested as slow oscillations and rapid transients of [Ca2+] i. LÄS MER

  4. 3. ATP Dynamics in Pancreatic α- and β-cells

    Författare :Jia Li; Anders Tengholm; Erik Gylfe; Hindrik Mulder; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATP; Ca2 ; β-cell; α-cell; SERCA; SOCE; muscarinic receptor; insulin secretion; glucagon secretion; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Glucose metabolism in pancreatic α- and β-cells is believed to regulate secretion of glucagon and insulin, respectively. In β-cells, ATP links glucose metabolism to electrical activity and insulin secretion. LÄS MER

  5. 4. Studies of the Effect of Enterovirus Infection on Pancreatic Islet Cells

    Författare :Asma Basheir Elshebani; Gun Frisk; Heiki Hyöty; Uppsala universitet; []
    Nyckelord :Medical sciences; type 1 diabetes; Human pancreatic islets; β-cells; chemokines; enterovirus; MEDICIN OCH VÅRD;

    Sammanfattning : Enterovirus (EV) infections have been associated with the pathogenesis of Type 1 Diabetes (T1D). However, the pathway(s) by which EV may induce or accelerate diabetes is not well understood. LÄS MER

  7. 5. FGFs and Wnts in pancreatic growth and β-cell function

    Författare :Stella Papadopoulou; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Wnt; FGF; pancreas; Notch; signal transduction; development; proliferation; progenitors; β-cells; feedback; GSIS; diabetes; Molekylärbiologi; Molecular biology; Molekylärbiologi;

    Sammanfattning : Mesenchymal-epithelial interactions are pivotal for proper pancreatic growth and development. The pancreatic progenitor cells present in the early pancreatic anlagen proliferate and eventually give rise to all pancreatic cell types. LÄS MER
