  1. 21. 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. 22. 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. 23. Platelet function in polycythemia vera : studies of agonist and cytokine induced platelet activation

    Författare :Katarina Le Blanc; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    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

  5. 24. Regulation of phagocytosis and phagolysosome fusion in human leukocytes

    Författare :Maria Lindmark; Per-Arne Oldenborg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Professional phagocytes such as neutrophil granulocytes and macrophages are an esential part of the innate immune system. The neutrophils form the first line of defence against invading microorganisms and are important for rapid killing of the intruders. LÄS MER

  7. 25. Signal transduction in human phagocytic cells during phagocytosis, oxidative activation and apoptosis

    Författare :Maria Forsberg; Emmanuelle Caron; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Neutrophils and macrophages are professional phagocytic cells that play a crucial role in host defense against invading microorganisms. They bind to, internalize, and subsequently kill microbes with an arsenal of reactive oxygen metabolites and microbicidal agents. LÄS MER
