  1. 11. Compartmentalisation of the immune response in human skin : cross-talk between dendritic cells and T cells in healthy conditions and in psoriasis

    Författare :Elisa Martini; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Human skin is highly compartmentalised and distinct subsets of dendritic cells (DCs) and T cells reside in epidermis and dermis. Alterations in the composition of DCs and T cells have been observed in psoriasis, a common cytokine-driven focal inflammatory skin disease. LÄS MER

  3. 12. T cell subsets and disease mechanisms in inflammatory myopathies

    Författare :Jayesh Pandya; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The idiopathic inflammatory myopathies (IIMs) are a heterogeneous group of chronic muscle disorders, typically displaying infiltrating T cells in skeletal muscle tissue and classified into polymyositis, dermatomyositis and sporadic inclusion body myositis. Several studies involving both humans and animal models point towards a role for T cells in the pathogenesis of IIMs, however, the precise phenotype, functionality and specificity of pathogenic T cells remain elusive.

  4. 13. Genetic studies of susceptibility to inflammation, autoimmunity, and hematological malignancy

    Författare :Bianca Tesi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The immune system represents the body’s defense against infectious organisms. Inborn defects of the immune system, called primary immunodeficiencies (PIDs), are a heterogeneous group of Mendelian disorders. Clinically, PIDs can cause isolated to broad susceptibility to pathogens, severe hyperinflammation, autoimmunity, allergy, and cancer. LÄS MER

  5. 14. Functional assays for the diagnosis of primary defects in lymphocyte cytotoxicity

    Författare :Samuel C C Chiang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cytotoxic lymphocytes encompass natural killer (NK) cells and cytotoxic T lymphocytes (CTL). These cells detect and kill virus-infected as well as malignant cells. Primary defects in lymphocyte cytotoxicity are associated with development of a hyperinflammatory syndrome termed hemophagocytic lymphohistiocytosis (HLH). LÄS MER

  7. 15. Human intestinal T lymphocytes : a comparative analysis of phenotype and function in normal and inflamed mucosa

    Författare :Silvia Melgar; Nadine Cerf-Bensussan; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human intestinal mucosa; intraepithelial lymphocyte; lamina propria lymphocyte; γδ T cell; regulatory T cell; cytotoxicity; cytokine; basal lymphoid aggregate; ulcerative colitis; Crohn s disease;

    Sammanfattning : The epithelial lining of the gut must allow immediate contact with beneficial components as nutrients and normal microflora. At the same time it runs the constant risk of attack from pathogenic microbes and noxious agents. LÄS MER
