  2. 21. Molecular epidemiologic studies on helicobacter pylori infection and stomach cancer risk

    Author : Zongli Zheng; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Helicobacter pylori;

    Abstract : Helicobacter pylori (H. pylori) infection increases stomach cancer risk. The aim of this thesis was to study genetic susceptibility from the host and to develop molecular methods for future characterization of bacterial virulence factors in longitudinal cohorts. READ MORE

  4. 22. Helicobacter pylori infection and immunity. Protection after vaccination and regulation of inflammation in a mouse model

    Author : Sukanya Raghavan; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter pylori; formalin-inactivated H. pylori; post-immunization gastritis; cholera toxin; CD4 CD25 regulatory T cells; CpG ODN;

    Abstract : Helicobacter pylori infection is an important cause of chronic active gastritis and peptic ulcer disease and a risk factor for the development of gastric cancer. An attractive strategy in the control of H. pylori infection is the development of a safe and effective therapeutic vaccine. Using a mouse model of H. READ MORE

  5. 23. Diversity and persistence of Helicobacter pylori

    Author : Annelie Lundin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Helicobacter pylori; genomic diversity; cag pathogenicity island; Nudix hydrolase;

    Abstract : Helicobacter pylori is an exceptionally diverse bacterial species, and every infected individual harbors a unique strain, apart from the strain concordance found in some families. The infection is usually acquired during childhood and once established, persists for life unless treated with antibiotics. READ MORE

  6. 24. Function of natural killer cells in Helicobacter pylori infection and gastric cancer

    Author : Åsa Lindgren; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Natural killer cells; Helicobacter pylori; gastric cancer; IFN-γ; TLR;

    Abstract : Helicobacter pylori infection is one of the most wide-spread infections in the world and causes a chronic inflammation in the gastrointestinal mucosa characterised by increased production of IFN-γ and is associated with an increased risk of developing gastric cancer. The mechanisms behind the development of gastric cancer in H. READ MORE

  7. 25. Development of novel molecular methods for Campylobacter species and for Helicobacter pylori

    Author : Kristina Blom; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Campylobacter; Helicobacter pylori; PCR; mRNA; hybridization; flow cytometry; HpaA; urease; NAP;

    Abstract : Background and Aim: Different Campylobacter species and Helicobacter pylori are common causes of gastrointestinal infections that may result in diarrhea and chronic gastritis, respectively. The overall aim of this thesis was to develop novel methods for identification, differentiation and characterization of these bacteria. READ MORE
