  1. 1. Barrier function of the Follicle-Associated Epithelium in Stress and Crohn's disease

    Författare :Åsa Keita; Johan D. Söderholm; Ann-Charlott Ericson; Björn Weström; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Corticotropin-releasing hormone; Crohn’s disease; 51Cr- EDTA; Escherichia coli; follicle-associated epithelium; horseradish peroxidase; human; ileum; inflammatory bowel disease; intestinal mucosa; mast cell; M cell; permeability; Peyer’s patches; rat; Ussing chamber; vasoactive intestinal peptide; villus epithelium; Surgery; Kirurgi;

    Sammanfattning : Crohns sjukdom är en kronisk inflammatorisk tarmsjukdom av okänd orsak. Det tidigaste tecknet på Crohns sjukdom är mikroskopiska sår i det s.k. follikelassocierade epitelet (FAE) som täcker ansamlingar av immunceller i tarmen. LÄS MER

  3. 2. Airway epithelial shedding: Morphological and functional aspects in vivo

    Författare :Jonas Erjefält; Luftvägsinflammation; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; eosinophils; neutrophils; plasma exudation; barrier restitution; basal cells; ciliated cells; secretory cells; Epithelial repair; epithelial shedding; fibrinogen; fibronectin; Respiratory system; Andningsorganen;

    Sammanfattning : Epithelial damage may contribute to the pathology in airway diseases such as asthma and rhinitis. However, the distribution of epithelial shedding in inflammatory airway diseases and, particularly, the ensuing repair processes are largely unknown. LÄS MER

  4. 3. Serine protease inhibitors in the upper and lower airways

    Författare :Camilla Hollander; Enheten för kroniska inflammatoriska och degenerativa sjukdomar; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; auditive system and speech; Neutrophils; audiology; Otorhinolaryngology; Medicin människa och djur ; AAT; Medicine human and vertebrates ; SLPI; cytokines chemokines; anti-proteases; audiologi; hörsel- och talorganen; Airway inflammation; Otorinolaryngologi;

    Sammanfattning : Proteases and their inhibitors are implicated in the physiology and pathology of the airways. Protease inhibitors include those produced locally, such as secretory leukocyte protease inhibitor (SLPI), and those produced mainly by the liver that can reach the airways via passive diffusion, such as alpha1-antitrypsin (AAT).

  5. 4. Laminin G Domains, their Receptors, and Activation of Intracellular Pathways

    Författare :Hao Yu; Klinisk minnesforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicinska vetenskaper allmänt ; General biomedical sciences; cell-matrix interaction; signaling; receptor; Basement membrane; laminin;

    Sammanfattning : Basement membranes are sheet like structures underlying epithelial, endothelial, adipocytes, muscle and peripheral nerve cells. Laminins are an important family of basement membrane proteins implicated in various biological functions through their interactions with cell surface receptors. Laminins are trimers composed of a, b and g chains. LÄS MER

  7. 5. Helicobacter pylori Sialic Acid-Specific Surface Lectin

    Författare :Siiri Hirmo; Enheten för infektionssjukdomar; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bakteriologi; mycology; Mikrobiologi; virology; bacteriology; haemagglutinin; Helicobacter pylori; sialic acid; sialidase; gastrointestinal mucin; milk glycoprotein; Microbiology; resonant mirror biosensor; virologi; mykologi;

    Sammanfattning : Helicobacter pylori is a gastric pathogen colonising the gastric mucus layer and epithelium of gastric tissue and is associated with chronic type B gastritis and peptic ulcer disease. The attachment of H. pylori to gastric epithelial cells involves several structures recognised by specific bacterial surface proteins. LÄS MER
