  1. 11. Severe Streptococcus pyogenes disease in Europe; epidemiology and clinical manifestations

    Författare :Bogdan Luca; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Streptococcus pyogenes; streptococcal toxic shock syndrome; necrotising fasciitis; emm-type; invasive GAS disease; superantigen;

    Sammanfattning : Streptococcus pyogenes, gives rise from mild skin infections and pharyngitis, to life threatening infections like bacteraemia, cellulitis, puerperal sepsis, meningitis, pneumonia, necrotizing fasciitis (NF), and streptococcal toxic-like shock syndrome (STSS), or nonsuppurative sequelae, rheumatic fever and glomerulonephritis. In 2002, the first multinational network for invasive GAS disease surveillance was initiated by the EU-funded Strep-EURO project. LÄS MER

  3. 12. On the induction and function of Foxp3+ regulatory T cells

    Författare :Cecilia Oderup; Diabetes - immunovirologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunologi; serologi; transplantation; regulatory T cell; serology; Immunology; superantigen; costimulation; dendritic cell; Foxp3;

    Sammanfattning : This thesis is based on three original papers with the overall aim to study the mechanisms of induction and function of Foxp3+CD4+CD25+ regulatory T cells. Regulatory T cells induce down-modulation of costimulatory molecules CD80 and CD86 on dendritic cells in vitro. LÄS MER

  4. 13. The ups and downs of T cells The role of costimulatory molecules in the modulation of T cell responses

    Författare :Christina Olsson; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunologi; transplantation; serology; CD28; costimulation; CD152; IL-2; NF-kB; AP-1; superantigen; Immunology; T cell; serologi;

    Sammanfattning : T cell activation requires the combination of antigen in the context of MHC and costimulatory molecules to induce a functional immune response. For our studies, we primarily utilized superantigens (SAg) that bind MHC class II molecules as first signal. LÄS MER
