1. Role of extracellular ATP in immune mechanisms against infections
Sammanfattning : Inflammation is driven either by infection with pathogens or sterile stimuli, such as tissue damage or autoimmune diseases. Upon tissue damage, ATP is released passively from the dead or compromised cells. During stress, ATP can be secreted from the cells. Extracellular ATP (eATP) acts as an endogenous danger signal.

2. Chemical studies of 0-antigens from Shigella
Sammanfattning : The structure of 13 types of Shigella flexneri O-antigens has been determined, using a N-deacetylation-deamination reaction sequence. The correlation between chemical structures and immunological classification of Shigella flexneri is discussed. LÄS MER
3. Characterization of Shigella dysenteriae type 1 hybrid vaccine candidates
Sammanfattning : Shigellae is endemic in many developing countries in the world and a major cause of childhood diarrheal morbidity and mortality. Infections caused by Shigella dysenteriae type 1 are particularly severe. LÄS MER
4. Prediction of 3D structures of oligosaccharides. Methodological development and studies on saccharide antigens of interest for vaccine design
Sammanfattning : This thesis presents 3D structure predictions of five immunologically active surfacepolysaccharides of pathogens, which are of interest as targets for development of glycoconjugatevaccines. Furthermore it describes two methods which have been used for theconformational predictionsThe Shigella dysenteriae type 2 Oantigenwas predicted to form a compact helicalstructure with three repeating pentasaccharide units per turn.

5. Central line-associated bloodstream infection and application of high resolution melting to methicillin resistant Staphylococcus aureus and Shigella sonnei genotyping
Sammanfattning : Effective infection prevention and control hospital program is essential for prevention hospital associated infections (HAIs). Central line-associated bloodstream infection (CLABSI) is one of the major threating patients in intensive care units (ICUs). LÄS MER
