  1. 6. Innate immunity of human intestinal epithelium in childhood celiac disease : influences from celiac disease associated bacteria and dietary oats

    Författare :Grzegorz Pietz; Marie-Louise Hammarström; Thomas T MacDonald; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Celiac disease; dietary oats; gut microbiota; intestinal epithelium; IEL; IFN-γ; IRF1; IL-18; CXC3L1; inflammasome; permeability; Prevotella jejuni; Lachnoanaerobaculum umeaense; immunologi; Immunology;

    Sammanfattning : Background & Aims: Celiac disease (CD) is a chronic inflammatory small-bowel enteropathy caused by permanent intolerance to gliadin in wheat gluten, and related proteins in ray and barley. It is disputed whether CD patients tolerate oats. The only treatment of CD is lifelong gluten-free diet (GFD). LÄS MER

  3. 7. Human intestinal epithelial cells in innate immunity : interactions with normal microbiota and pathogenic bacteria

    Författare :Gangwei Ou; Sten Hammarström; Marie-Louise Hammarström; Agnes Wold; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; immunologi; Immunology;

    Sammanfattning : Rod-shaped bacteria were previously shown to be associated with the small intestinal epithelium of children with celiac disease (CD). Using culture-dependent and independent methods, we characterized the microbiota of small intestine in children with CD and controls. The normal microbiota constitutes an unique organ-specific biofilm. LÄS MER

  4. 8. Butyrophilin- and Butyrophilin-like genes and their role in epithelial cell-intraepithelial T lymphocyte cross-talk

    Författare :Cristina Lebrero-Fernandez; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Butyrophilin-like Btnl ; Butyrophilin Btn ; Intraepithelial lymphocytes IELs ; Mucosal immunity; Intestinal epithelial cells; γδ T cells; Intestinal inflammation; Colon cancer; Ulcerative colitis;

    Sammanfattning : More than 50% of our immune system is located in the gut. The intestinal epithelium, which forms an interface between the organism and the environment, harbors intraepithelial lymphocytes (IELs) that comprise a mixture of conventional αβ T cells and unconventional αβ- and γδ T cells.

  5. 9. Isoform-specific regulation of Drosophila gut immunity and regeneration by the POU/Oct transcription factor Nub/Pdm1

    Författare :Xiongzhuo Tang; Ylva Engström; Tony Ip; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; POU; Nubbin; Drosophila; intestinal stem cell; epithelium regeneration; midgut; mitosis; Antimicrobial peptides; innate immunity; NF-κB; bacterial infection; transcriptional regulation; homeostasis; Molecular Biology; molekylärbiologi;

    Sammanfattning : Innate immune reactions protect organisms against a variety of infections.  In metazoans, these reactions involve both cellular and humoral responses. The immune responses have to be well-tuned, as excessive immune activation is associated with tissue-specific pathologies. LÄS MER

  7. 10. Helminths and immunity against tuberculosis

    Författare :Daniel Elias; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :tuberculosis; BCG; helminths; immunomodulation; vaccination;

    Sammanfattning : The efficacy of Bacille Calmette Guerin (BCG) is low and incidence of tuberculosis (TB) is high in those areas where helminths are endemic. Protection against tuberculosis requires strong cell mediated immunity while chronic helminth infections induce responses characterized by dominant Th2 responses as well as up-regulated regulatory T cell activity.
