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

22. LIPASES AND PHOSPHOLIPASES IN PHOSPHOLIPID SYNTHESIS
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
23. Platelet function in polycythemia vera : studies of agonist and cytokine induced platelet activation
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
24. Regulation of phagocytosis and phagolysosome fusion in human leukocytes
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
25. Signal transduction in human phagocytic cells during phagocytosis, oxidative activation and apoptosis
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
