  2. 11. Role of TLR4 in Escherichia coli urinary tract infection

    Author : Patrik Samuelsson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mykologi; virologi; mycology; Mikrobiologi; bakteriologi; serologi; transplantation; Microbiology; virology; bacteriology; Immunologi; serology; Immunology; Pathogen; Mucosa; P-fimbriae; Toll like receptor;

    Abstract : 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. READ MORE

  4. 12. Studies of the pathogenesis of Enterohemorrhagic Escherichia coli infections: pathogen virulence factors and host response

    Author : Carla Calderon Toledo; Lund Pediatrik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; host-pathogen; MyD88; TLRs; LEE; Shiga toxin; HUS; EHEC; EPEC; immune response; virulence factors;

    Abstract : 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. READ MORE

  5. 13. NMR studies of host-pathogen interactions

    Author : Katja Petzold; Jürgen Schleucher; Torleif Härd; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR; regulatory RNA; HBV; H.pylori; phospholipids; ROESY; Molecular biophysics; Molekylär biofysik; biokemi; Biochemistry;

    Abstract : 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. READ MORE

  6. 14. Neoehrlichia mikurensis in Sweden : An emerging tick-borne human pathogen

    Author : Lisa Labbé Sandelin; Björn Olsen; Jonas Waldenström; Per-Eric Lindgren; Ivar Tjernberg; Lars Hagberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neoehrlichia; Tick-borne Infections; Transfusion-transmitted infections; Bacterial Zoonotic infections; Blood Donors; Immunosuppression; Infectious Diseases; Emerging; Blood Safety; Bird Migration; Infektionssjukdomar; Infectious Diseases;

    Abstract : 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. READ MORE

  7. 15. Host-Pathogen Responses during Giardia infections

    Author : Emma Ringqvist; Staffan Svärd; Patricia Johnson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Giardia; parasite infection; host-parasite releationship; immune activation; virulence factor; immune evasion; Cell and molecular biology; Cell- och molekylärbiologi; Microbiology; Mikrobiologi; mikrobiologi; Microbiology;

    Abstract : 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. READ MORE
