  2. 22. Regulation of docking and priming in pancreatic α- and β-cells

    Författare :Muhmmad Omar-Hmeadi; Sebastian Barg; Patrick MacDonald; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type-2 diabetes; glucagon; insulin; somatostatin; exocytosis;

    Sammanfattning : The secretion of islet hormones from endocrine cells of the pancreas plays vital roles in maintaining glucose homeostasis. Dysfunction of these cells leads to diabetes, a devastating metabolic disorder affecting millions worldwide, but underlying mechanisms remain poorly understood. LÄS MER

    Sammanfattning : Growing concern regarding climate change calls for sustainable solutions to significantly reduce our dependency on non-renewable fossil-based raw materials. One potential solution is the development of biorefineries where biobased, renewable raw materials are converted into valuable products via enzymatic, chemical or microbial conversion. LÄS MER

  4. 24. Genetic pathways controlling CNS development : The role of Notch signaling in regulating daughter cell proliferation in Drosophila

    Författare :Caroline Bivik Stadler; Stefan Thor; Jan-Ingvar Jönsson; Allison Bardin; Linköpings universitet; []

    Sammanfattning : The human central nervous system (CNS) displays the greatest cellular diversity of any organ system, consisting of billions of neurons, of numerous cell sub-types, interconnected in a vast network. Given this enormous complexity, decoding the genetic programs controlling the multistep process of CNS development remains a major challenge. LÄS MER

  5. 25. Function of MAP20 and MYB103 in cellulose and lignin formation of xylem secondary cell walls

    Författare :David Öhman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
