  1. 1. Adaptation of Helicobacter pylori Adherence Properties in Promotion of Host Tropism and Inflammatory Disease

    Author : Marina Aspholm; Rino Rappuoli; [2004]
    Keywords : H. pylori; BabA; SabA; adhesin; blood group antigens; sialylated; phase variation; hemagglutination; selectin; adaptation; odontologi; Odontology;

    Abstract : Being among the most prevalent of persistent infectious agents in humans worldwide, Helicobacter pylori induces chronic inflammation (gastritis), which may progress to peptic ulceration and stomach cancer. The ability to adhere to the gastric mucosa is considered to be both a colonization and virulence property of H. pylori. For adherence, H. READ MORE

  2. 2. Multifaceted adhesion properties of Helicobacter pylori in promotion of gastric disease

    University dissertation from Umeå : Umeå universitet

    Author : Jenny Nordén; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Helicobacter pylori is a Gram-negative spiral-shaped bacteria that resides in the gastric mucosa and adheres to the epithelial lining of the human stomach. H. pylori adhesion mediates inflammation of the epithelium, which can lead to more severe diseases such as chronic active gastritis and gastric carcinoma. READ MORE

  3. 3. Helicobacter pylori bacterial adhesion and host response

    University dissertation from Umeå : Umeå universitet

    Author : Farzad Olfat; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Communicable diseases; Infektionssjukdomar; MEDICINE Microbiology; immunology; infectious diseases Infectious diseases; MEDICIN Mikrobiologi; immunologi; infektionssjukdomar Infektionssjukdomar;

    Abstract : The gastric pathogen Helicobacter pylori infects more than half of the population worldwide. H. pylori manage to establish persistent infection, which would be life-long if not treated. In order to establish such an infection, this pathogen has to deal with the host immune system. READ MORE

  4. 4. Targeting the human glycoproteome: new enrichment protocols and mass spectrometric analyses reveal unique and novel glycosylation sites

    University dissertation from Göteborg : University of Gothenburg

    Author : Adnan Halim; Göteborgs universitet.; Gothenburg University.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glycobiology; Glycoproteomics; Mass Spectrometry;

    Abstract : Glycosylation is one of the most common and structurally diverse posttranslational modifications of proteins. Given that protein glycosylation is involved in various cellular processes, the characterization of site-specific N- and O-linked glycosylations is becoming increasingly important. However, current mass spectrometry-based technologies, i.e. READ MORE

  5. 5. Sialic acid-dependent binding specificities of Helicobacter pylori and influenza virus. Importance of different parts of the binding sequences

    University dissertation from Göteborg : University of Gothenburg

    Author : Petra Johansson; Göteborgs universitet.; Gothenburg University.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sialic acid; carbohydrates; Helicobacter pylori; influenza virus; binding specificities; glycosphingolipids;

    Abstract : Many viruses and bacteria adhere to host cell glycoconjugates in a specific manner, utilizing selected carbohydrate sequences. The aim of this work was to investigate at a molecular level the interactions of two important human pathogens, influenza virus and Helicobacter pylori, with sialylated carbohydrate structures.
