  1. 6. The ontogeny and function of intestinal dendritic cells

    Författare :Emma Persson; Slemhinnans immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mesenteric lymph nodes; Intestine; Dendritic cells; Gut-homing; Th17 cells; Oral tolerance; Immunity;

    Sammanfattning : The intestinal mucosa presents a huge surface area to the external environment and the intestinal immune system is continually exposed to a wide array of foreign antigens derived from resident intestinal microbiota as well as dietary constituents, including food proteins. In order to maintain intestinal homeostasis, the intestinal immune system relies on the ability to generate tolerogenic responses to innocuous antigen while maintaining the ability to develop effective immune responses to intesinal pathogens.

  2. 7. THE INFLUENCE OF LACTOBACILLI AND STAPHYLOCOCCUS AUREUS ON IMMUNE RESPONSIVENESS IN VITRO

    Författare :Yeneneh Haileselassie; Eva Sverremark-Ekström; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cytokine; T cells; immune response; HT-29; Intestinal epithelial cells; Lactobacillus; Staphylococcus aureus; bacteria and infants; immunologi; Immunology;

    Sammanfattning : Alteration of gut microbiota has been associated with development of immune mediated diseases, such as allergy. In part, this could be due to the influence of microbes in shaping the immune response. LÄS MER

  3. 8. Immune maturation and lymphocyte characteristics in relation to early gut bacteria exposure

    Författare :Sophia Björkander; Eva Sverremark Ekström; Hanne Frøkiær; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Allergy; cell-free supernatant; chemokines; colonization; cytokines; FOXP3; immune-maturation; lactobacilli; lymphocytes; NK-cells; Staphylococcus aureus; unconventional T-cells; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : At birth, the immune system is immature and the gut microbiota influences immune maturation. Staphylococcus aureus (S. aureus) and lactobacilli are part of the neonatal gut microbiota and have seemingly opposite effects on the immune system. S. LÄS MER

  4. 9. Functions and memory features of adaptive- and innate immune cells in physiological and inflammatory settings

    Författare :Gintare Lasaviciute; Eva Sverremark-Ekström; Silke Appel; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Innate immune memory; Limosilactobacillus reuteri; dendritic cells; lymphocytes; cytokines; immunological memory; intestinal epithelial cells; chemotherapy; bone marrow; secondary lymphoid organs; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : The immune system is a complex but well-regulated network which cooperates with the microbiota to maintain optimal homeostasis under physiological settings. A number of factors display the capacity to alter the immune system and thus microbiota crosstalk including host genetics, diet, environmental influences and drugs such as antibiotics or chemotherapeutic agents.

  5. 10. Fermented probiotic beverage based on quinoa : Functionality, hygiene, and health effects

    Författare :Pamela Rosario Canaviri Paz; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Quinoa grains; Fermentation; Lactic acid bacteria; Probiotics; Food safety; Starter culture; Polyphenol compounds; Microbiota composition; Functional food; Gut microbiota;

    Sammanfattning : White quinoa grains were used as a source of novel beneficial microorganisms and as a matrix for development of a fermented plant-based drink. Studies on the quinoa grain microbiota were performed by applying spontaneous fermentation to allow isolation of autochthonous Lactiplantibacillus strains with potential to be used as starter cultures.
