  1. 11. Evolutionary and functional studies of protein H: a surface molecule of Streptococcus pyogenes

    Författare :Inga-Maria Frick; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intracellular transportation; adhesion; aggregation; FNIII domain; albumin-binding; M-like protein; convergent evolution; protein G; Streptococcus pyogenes; IgG-binding; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Several bacterial species express surface proteins with affinity for the Fc part of human IgG. This thesis describes evolutionary and functional studies of protein H, an IgGFc-binding surface protein of the human pathogen Streptococcus pyogenes. LÄS MER

  3. 12. Helicobacter pylori Sialic Acid-Specific Surface Lectin

    Författare :Siiri Hirmo; Enheten för infektionssjukdomar; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bakteriologi; mycology; Mikrobiologi; virology; bacteriology; haemagglutinin; Helicobacter pylori; sialic acid; sialidase; gastrointestinal mucin; milk glycoprotein; Microbiology; resonant mirror biosensor; virologi; mykologi;

    Sammanfattning : Helicobacter pylori is a gastric pathogen colonising the gastric mucus layer and epithelium of gastric tissue and is associated with chronic type B gastritis and peptic ulcer disease. The attachment of H. pylori to gastric epithelial cells involves several structures recognised by specific bacterial surface proteins. LÄS MER

  4. 13. Analysis of the molecular interplay between Streptococcus pyogenes and its human host

    Författare :Björn Johansson; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; bacteriology; virology; mycology; Biomedicinska vetenskaper allmänt ; Regulation; General biomedical sciences; IdeS; Enzyme; Virulence factors; Virulence; Bacteria; Streptococci; bakteriologi; virologi; mykologi; GAS; Protein; Mikrobiologi;

    Sammanfattning : The common human pathogen Streptococcus pyogenes is the causative agent of numerous mild and severe clinical conditions. It expresses a number of secreted or cell wall-anchored proteins that modulate the human immune system and facilitate colonization and spread of the pathogen in the human host. During S. LÄS MER

  5. 14. Immunoglobulin-binding bacterial surface proteins; biomedical tools and virulence factors

    Författare :Britt-Marie Kihlberg; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Phagocytosis; M-like protein; M protein; Protein L; Protein G; Ig-binding; Streptococcus pyogenes; Fc Receptors; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; virology; bacteriology; Microbiology; Cysteine proteinase; Streptolysin;

    Sammanfattning : Many bacteria express immunoglobulin(Ig)-binding proteins that interact with Ig in a non-immune manner. Several of these Ig-binding bacterial proteins have been well characterized and are widely used as reagents for analysis and purification of Ig's. LÄS MER

  7. 15. Staphylococcal induced inflammatory response in human monocytes: Analysis of factors involved

    Författare :Eva Mattsson; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; interleukin-6; interleukin-beta; TNF-alfa; teichoic acid; Staphylococcus epidermidis; peptidoglycan; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Purified bacterial cell wall components peptidoglycan and teichoic acid were isolated from staphylococcal species S. aureus and/or S. epidermidis and tested for their ability to induce cytokine release from plastic-adherent human monocytes. LÄS MER
