    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; macromolecule; endocytosis; FITC-dextran; secretion; mucosa; CCK; pancreas; disaccharidase; intestinal permeability; lectin; morphometry; Animal physiology; Djurfysiologi;

    Sammanfattning : The gastrointestinal tract has two opposing functions; to effectively absorb nutrients and to act as a safety barrier against hazardous substances in the environment. After birth these functions develops gradually. LÄS MER

  3. 22. Role of TLR4 in Escherichia coli urinary tract infection

    Författare :Patrik Samuelsson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mykologi; virologi; mycology; Mikrobiologi; bakteriologi; serologi; transplantation; Microbiology; virology; bacteriology; Immunologi; serology; Immunology; Pathogen; Mucosa; P-fimbriae; Toll like receptor;

    Sammanfattning : In this thesis we have used P fimbriated E. coli as a model to investigate the mechanisms of bacterial recognition and cell activation by the urinary tract (UT) epithelium. We show that Toll like receptor 4 (TLR4) is crucial for the recognition and host response to P fimbriated E. coli. LÄS MER

  5. 24. Helicobacter pylori interference with the L-arginine/NO pathway in the upper gut

    Författare :Charlotte Von Bothmer; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acid; bicarbonate; duodenal ulcer; Helicobacter pylori; host defence; mucosa; nitric oxide; nitric oxide synthase;

    Sammanfattning : Helicobacter pylori causes chronic gastritis and sometimes peptic ulcers but the pathogenesis is not fully understood. H. pylori-infected individuals with duodenal ulcer have an impaired duodenal mucosal bicarbonate secretion (DMBS) in response to acid. NO is an important signalling molecule in the body. LÄS MER

  7. 25. Tissue-Selective Activation and Toxicity of Substituted Dichlorobenzenes : Studies on the Mechanism of Cell Death in the Olfactory Mucosa

    Författare :Anna Franzén; Eva Brittebo; Ingvar Brandt; Olavi Pelkonen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toxicology; tissue-selective toxicity; bioactivation; olfactory mucosa; substituted dichlorobenzenes; Bowman s glands; sustentacular cells; ER stress; Grp78; caspase-12; caspase-3; CYP2A5; protein adduction; nasal toxicity; Toxikologi; Toxicology; Toxikologi;

    Sammanfattning : The nasal passages are constantly exposed to both air- and bloodborne foreign compounds. In particular, the olfactory mucosa is demonstrated to be susceptible to a variety of drugs and chemicals. LÄS MER
