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

    Author : Jonas Erjefält; Luftvägsinflammation; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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;

    Abstract : 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. READ MORE

  4. 2. Pathogenic Neisseria infections of human neutrophils and epithelial cells : focusing on host responses and immune evasion

    Author : Niklas Söderholm; Helena Aro; Thomas Rudel; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Neisseria meningitidis; Neisseria gonorrhoeae; Neutrophils; PMN; Epithelial cells; Polarized cells; Type IV pili; Adherence; Cell cycle; DNA damage; Lactobacillus; molekylär biovetenskap; Molecular Bioscience;

    Abstract : N. meningitidis and N. gonorrhoeae are obligate human pathogens that colonize mucosal surfaces and are often carried asymptomatically. These bacteria have developed adhesive structures that promote adherence to host cells and efficient colonization of new hosts. READ MORE

  5. 3. New Approaches to Studies of Paracellular Drug Transport in Intestinal Epithelial Cell Monolayers

    Author : Staffan Tavelin; Per Artursson; Staffan Tavelin; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; intestinal epithelium; tight junctions; cell culture; Galenisk farmaci; Pharmaceutics; Galenisk farmaci; galenisk farmaci; Pharmaceutics;

    Abstract : Studies of intestinal drug permeability have traditionally been performed in the colon-derived Caco-2 cell model. However, the permeability of these cell monolayers resembles that of the colon rather than that of the small intestine, which is the major site of drug absorption following oral administration.

  6. 4. Approaches to analyses of cytotoxic cells. And studies of their role in H. pylori infection

    Author : Josef Azem; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    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

  7. 5. Lactobacilli- and Staphylococcus aureus mediated modulation of immune responses in vitro

    Author : Yeneneh Haileselassie; Eva Sverremark-Ekström; Huub Savelkoul; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; lactobacilli; staphylococcus aureus; dendritic cells; retinoic acid; epithelial cells; T cells; immunologi; Immunology;

    Abstract : The human gut harbors a vast number of microbes. These microbes are not passive bystanders. They are important in modulating the immune system. We have previously shown that early colonization with lactobacilli and Staphylococcus (S. READ MORE
