  1. 6. Staphylococcal enterotoxin H - structure and function of a superantigen

    Författare :Helen Pettersson; Lunds universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; TCR; staphylococcal enterotoxin H; MHC class II; superantigen; transplantation; Immunologi; serologi; serology;

    Sammanfattning : The aim of this thesis was to characterise the biological functions of the superantigen staphylococcal enterotoxin H (SEH). Superantigens are highly immunostimulatory proteins, which crosslink T cells and antigen presenting cells (APCs). LÄS MER

  3. 7. Stress induced virulence of Staphylococcus aureus and Listeria monocytogenes

    Författare :Nikoleta Zeaki; Teknisk mikrobiologi; []
    Nyckelord :;

    Sammanfattning : Control of the dissemination of pathogens in the food production chain is an on-going process with new challenges emerging as pathogenic bacteria evolve and express enhanced virulence characteristics. Staphylococcus aureus and Listeria monocytogenes are two notorious pathogens responsible for staphylococcal food poisoning (SFP) and listeriosis: a foodborne intoxication and an infectious disease respectively.

  4. 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

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

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

    Sammanfattning : 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. LÄS MER

  7. 10. Activation of murine cytotoxic cells with interelukin-2 and the bacterial superantigen staphylococcal entertoxin A

    Författare :Hans Belfrage; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunologi; transplantation; serology; Immunology; cytokine; tolerance; LAK; NK; serologi; CTL; Staphylococcal enterotoxin A; SEA; Interleukin-2; murine; deletion; anergy;

    Sammanfattning : Natural killer (NK) cells and T lymphocytes are the major effector cells that can recognize and kill tumor cells. NK cells have a constitutive cytotoxic activity and kill a wide spectrum of tumor cells while T cells recognize specific tumor antigens and need to be activated through their TCR to differentiate into cytotoxic T lymphocyte (CTL) killers or T helper cells.
