  1. 1. The immunomodulatory function of staphylococcal superantigen on oral tolerance

    Författare :Anna Stern; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oral tolerance; superantigen; hygiene hypothesis; staphylococcal enterotoxin;

    Sammanfattning : Exposure to soluble proteins via the gut gives rise to systemic tolerance, a phenomenon called oral tolerance. Failure of oral tolerance results in allergy, a disease that has increased during the last decades in Western industrialized countries. The cause of this rapid increase is unknown. LÄS MER

  3. 2. Aspects of Staphylococcus aureus in Chronic Rhinosinusitis

    Författare :Ulrica Thunberg; Bo Söderquist; Svante Hugosson; Hans Fredlund; Johan Hellgren; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chronic rhinosinusitis; Staphylococcus aureus; enterotoxins; immune response; SNP; clinical features;

    Sammanfattning : Chronic rhinosinusitis (CRS) affects about 10% of the European population, and is considered a great scourge. Its cause is not clear. Findings of Staphylococcus aureus in the maxillary sinus are common in CRS patients, but are usually regarded as insignificant due to the bacterium’s attribute as a commensal elsewhere. S. LÄS MER

  4. 3. Bacterial Regulation of Peripheral Immunity : Mechanistic insights from lactobacilli and Staphylococcus aureus

    Författare :Manuel Mata Forsberg; Eva Sverremark-Ekström; Monika Brunner-Weinzierl; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Immune regulation; Cytokines; T cells; gamma-delta T cells; MAIT cells; NK cells; Lactobacillus; Staphylococcus aureus; staphylococcal enterotoxins; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : There is a constant cross-talk between our immune system and the colonizing microbiota. The gut resident bacteria produce a broad range of molecules with regulatory activities in both local and distal tissues. Staphylococcus (S. LÄS MER

  5. 4. 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

  7. 5. Structural Basis of Immune Receptor Binding by Staphylococcal Superantigens

    Författare :Karin Rödström; Medicinsk strukturbiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Superantigen; X-ray Crystallography; T cell receptor; Major histocompatibility complex;

    Sammanfattning : Superantigens (SAgs) are toxins capable of inducing a massive immune response, leading to severe disease. They are secreted by the bacteria Staphylococcus aureus and Streptococcus pyogenes, which produce the staphylococcal enterotoxins and streptococcal pyogenic exotoxins, respectively. LÄS MER
