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
22. 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.

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
24. Mechanisms of Growth Hormone Signal Transduction - Studies on the insulin-like metabolic effects in primary rat adipocytes
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
25. 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
