11. Role of TLR4 in Escherichia coli urinary tract infection
Sammanfattning : In this thesis we have used P fimbriated E. coli as a model to investigate the mechanisms of bacterial recognition and cell activation by the urinary tract (UT) epithelium. We show that Toll like receptor 4 (TLR4) is crucial for the recognition and host response to P fimbriated E. coli. LÄS MER
12. Studies of the pathogenesis of Enterohemorrhagic Escherichia coli infections: pathogen virulence factors and host response
Sammanfattning : Enterohemorrhagic Escherichia coli (EHEC) is a highly virulent pathogen that can cause diarrhea and a life-threatening disease known as hemolytic uremic syndrome. EHEC possess an array of virulence factors that can exert severe consequences in the host. Shiga toxin constitutes a key virulence factor. LÄS MER
13. NMR studies of host-pathogen interactions
Sammanfattning : This thesis describes the use of Nuclear Magnetic Resonance (NMR) for characterizing two host-pathogen interactions: The behavior of a regulatory RNA of the Hepatitis B virus (HBV) and the attachment of Helicobacter pylori (H. pylori) to the gastric mucosa. LÄS MER
14. Neoehrlichia mikurensis in Sweden : An emerging tick-borne human pathogen
Sammanfattning : Neoehrlichia mikurensis is an emerging tick-borne human pathogen, causing neoehrlichiosis in immunosuppressed and immunocompetent individuals. It targets the vascular endothelium, leading to thromboembolic and vascular events, but can also pass without symptoms. LÄS MER
15. Host-Pathogen Responses during Giardia infections
Sammanfattning : Giardia lamblia is a eukaryotic parasite of the upper small intestine of humans and animals. The infecting trophozoite cells do not invade the epithelium lining of the intestine, but attach to the brush border surface in the intestinal lumen. The giardiasis disease in humans is highly variable. LÄS MER
