  2. 1. 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

  4. 2. Chronic gastritis in a sample of the general population : Helicobacter pylori infection, metaplastic transformation, epithelial proliferation, p53- and p21 expression and antral mucosal gastrin content with reference to gastric carcinoma development

    Author : Fredrik Petersson; Roger Stenling; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Infection with H. pylori is the main cause of chronic inflammation in the stomach. lt is strongly associated with benign ulcer disease and a risk factor for gastric carcinoma (GC). Different tophographical types of gastritis bear different risks for future development of GC. READ MORE

  5. 3. Experimental Helicobacter pylori infection in an animal model

    Author : Yi-Qian Sun; Torkel Wadström; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Background: Helicobacter pylori is a microaerophilic Gram-negative bacterium colonizing the human stomach. The prevalence of this infection is between 20-90% depending on geographic location. Comprehensive studies have shown significant relationships between H. pylori infection and chronic gastritis, peptic ulcer and gastric carcinoma. READ MORE

  6. 4. Microdialysis to study the Gastrin-ECL cell Axis in the conscious rat

    Author : Peter Ericsson; Drug Target Discovery; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The ECL cells constitute the major endocrine cell population in the acid-producing part of the stomach. Gastrin from G cells in the antrum is the main stimulus of gastric acid secretion. Gastrin stimulates the ECL cells in the oxyntic mucosa to mobilize histamine, which in turn stimulates the parietal cells to produce hydrochloric acid. READ MORE

  7. 5. The mucosal immune response against Helicobacter pylori infection

    Author : Sicheng Wen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : H. pylori infection affects more than half of the world’s population. The clinical consequences range from asymptomatic gastritis to peptic ulceration and gastric malignancy. H. READ MORE
