16. Helicobacter pylori and its Association with Gastric and Oesophageal Carcinomas
Sammanfattning : Helicobacter pylori is one of the most common infections in man. The infection is often acquired during childhood and usually results in a chronic life-long inflammation in the gastric mucosa. The aim of our studies was to investigate the association between H. pylori seropositivity and the development of gastric and oesophageal carcinomas. LÄS MER
17. Helicobacter pylori and gastric carcinogenesis : An experimental study of some preneoplastic events
Sammanfattning : Half the population in the world is chronically infected with H.pylori. This infection has been proven to be associated with gastritis, duodenal and gastric ulcers but also with gastric cancer and MALT-lymphoma. The aims of this thesis were to explore some possible mechanisms by which H. LÄS MER
18. Glycosphingolipid interactions of Helicobacter pylori and F1C-fimbriated Escherichia coli
Sammanfattning : The aim of this thesis was to investigate glycosphingolipid interactions of the human pathogens Helicobacter pylori and F1C-fimbriated uropathogenic Escherichia coli. Of particular interest were interactions of H. pylori to complex gangliosides, the role played by H. LÄS MER
19. Regulatory CD4+FOXP3+ T cells in Helicobacter pylori-induced disease
Sammanfattning : Helicobacter pylori colonize the gastric or duodenal mucosa of approximately half of the worlds’ population. Although most individuals are asymptomatic, H. pylori infection cause peptic ulcers or gastric cancer in 10-15 % and 1-2 %, respectively, of the infected individuals. LÄS MER
20. Role of lactobacilli in Helicobacter pylori pathogenesis and host cell responses
Sammanfattning : 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. LÄS MER
