2. 1. Recombinant mucin-type proteins as tools for studies on the interactions between Helicobacter pylori and its carbohydrate receptors

   Author : Yolanda H. Mthembu; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; O-glycans; mucins; glycosyltransferases; Helicobacter pylori; microbial adhesion;

   Abstract : Glycan-protein interactions are important in pathogen adhesion and infections. H. pylori has adhesins which enables it to bind to glycans on the gastric mucosa and, in the long run, cause gastric cancer. The reported current antibiotic regimen used in the treatment to eradicate H. READ MORE

4. 2. Role of lactobacilli in Helicobacter pylori pathogenesis and host cell responses

   Author : Hanna Gebreegziabher Gebremariam; Ann-Beth Jonsson; Keira Melican; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Helicobacter pylori; Inflammation; Lactobacillus; ADAM17; Proinflammatory cytokines; Lactate; molekylär biovetenskap; Molecular Bioscience;

   Abstract : Helicobacter pylori is well adapted to the harsh environment of the human stomach, allowing it to persistently colonize the gastric mucosa of at least 50% of the global population for decades. Long-term colonization induces chronic inflammation that can eventually lead to development of peptic ulcer and gastric cancer. READ MORE

5. 3. Approaches to analyses of cytotoxic cells. And studies of their role in H. pylori infection

   Author : Josef Azem; Göteborgs universitet; []
   Keywords : Helicobacter pylori; mucosal immunology; stomach; duodenum; asymptomatic; duodenal ulcer; gastric adenocarcinoma; NK cells; T cells; B cells; dendritic cells; cytotoxic;

   Abstract : Helicobacter pylori infection causes chronic gastritis that may progress to peptic ulcers or gastric adenocarcinoma and thereby cause major world-wide health problems. Previous studies have shown that CD4+ T cells and the production of the cytokine IFN- × are important components of the immune response to H. pylori in humans. READ MORE

6. 4. Mucus and mucins during gastrointestinal infections

   Author : Nazanin Navabi; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mucin; gastrointestinal cell lines; mucus layer; secreted mucin; cell surface mucin; H. pylori; C. rodentium; ETEC; mucin secretion; goblet cells;

   Abstract : The gastrointestinal tract is protected by a continuously secreted mucus layer formed by mucin glycoproteins. The mucus layer and mucins change dynamically during infection. The main focus of this thesis was to investigate the changes in mucin and the mucus layer in the gastrointestinal tract during infection with the gastrointestinal pathogens C. READ MORE

7. 5. Mucosal T-cell and cytokine responses in Helicobacter pylori-infected duodenal ulcer patients

   Author : Erika Strömberg; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter pylori; mucosal immunology; antrum; duodenum; duodenal ulcer; asymptomatic; epithelial cells; cytokines; T cells;

   Abstract : Helicobacter pylori colonizes the human stomach and areas of gastric metaplasia in the duodenum. The bacterium is the major cause of chronic active gastritis and peptic ulcer disease and is a risk factor for the development of gastric adenocarcinoma and lymphoma. READ MORE
