  1. 21. G-protein - cytoskeleton interactions in the human neutrophil during chemoattracant activation

    Författare :Eva Särndahl; Eduardo Lapetina; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The human body survives constant attacks by bacteria and other pathogens thanks to the surveillance of the neutrophil leukocytcs. At the site of an infection, several messenger molecules are generated that attract neutrophils from the blood and direct their migration toward the microbes. LÄS MER

  2. 22. Lipid Turnover in Plants and Yeast, A Study of Storage Lipid Synthesis and Lipid-Based Signalling in Plants and Yeast

    Författare :Maria Gustavsson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtbiokemi; Plant biochemistry; turnover; plasma membrane; plant; PLA2; biosynthesis; S. cerevisiae; triacylglycerol;

    Sammanfattning : In this thesis, lipid biosynthesis is discussed focussing on the genes and enzymes involved in the final step of storage lipid synthesis, on the enzyme phospholipase A2, and on cell membrane lipid homeostasis. The investigation of lipid metabolism revealed that in Saccharomyces cerevisiae, there are four genes that are essential for the final step of storage lipid biosynthesis; ARE1, ARE2, DGA1, and LRO1.

  3. 23. LIPASES AND PHOSPHOLIPASES IN PHOSPHOLIPID SYNTHESIS

    Författare :Carmen Virto; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transphosphatidylation; acylation; vinyl ester; Phospholipid synthesis; lysophospholipid; kinetics; Biotechnology; Bioteknik;

    Sammanfattning : The synthesis of phospholipids with defined fatty acid and polar head composition catalysed by lipases and phospholipases was investigated. Lipases from Rhizopus arrhizus and Candida antarctica were used for the direct acylation of DL-a-glycerophosphate and L-a-glycerophosphatidylcholine, with different fatty acids. LÄS MER

  4. 24. Mechanisms of Growth Hormone Signal Transduction - Studies on the insulin-like metabolic effects in primary rat adipocytes

    Författare :Hans Eriksson; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysiologi; Endocrinology; Growth hormone insulin receptor phosphorylation phosphotyrosine cAMP phosphodiesterase phospholipid JAK2 rat adipocyte lipolysis lipogenesis; Physiology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

    Sammanfattning : Growth hormone (GH) exerts growth-promoting and metabolic effects in mammals. The metabolic effects of GH in adipose tissue are insulin-antagonistic or insulin-like. Cells that just have been exposed to GH are insensitive to the hormone. LÄS MER

  5. 25. Platelet function in polycythemia vera : studies of agonist and cytokine induced platelet activation

    Författare :Katarina Le Blanc; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : Polycythemia vera (PV) is a malignant myeloproliferative disorder characterized by an increased red cell mass and most often accompanied by leukocytosis and thrombocytosis. The pathogenic mechanisms behind PV are still largely unknown. LÄS MER
