  1. 6. Resident T cells in human skin : functional heterogeneity and clinical implications

    Författare :Stanley Sing Hoi Cheuk; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The skin forms a critical barrier against the external environment and is therefore frequently challenged by infections and subjected to immune-mediated diseases as well as malignancies. The Tissue-Resident Memory T (TRM) cell is a subset of T cells that resides at sites of previous infection in the skin and other epithelial tissues. LÄS MER

  3. 7. Optimisation of dengue diagnostic tools in order to increase the knowledge of the pathogenesis

    Författare :Gunnel Lindegren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Dengue fever (DF) is the most common global viral mosquito-borne infection, with 100 million estimated cases annually in tropical and subtropical areas. The dengue viruses (genus Flavivirus, Flaviviridae) occur in 4 serotypes (DENV-1 to DENV-4). Dengue diseases range from a mild febrile disease to severe hemorrhagic fever. LÄS MER

  4. 8. Composition and maintenance of skin resident T-cells in health and disease

    Författare :Elena Hoffer; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Tissue-resident memory T cells (TRM) reside in healthy skin at sites of previous infections. Upon re-infection, TRM cells rapidly respond by initiating tissue inflammation and exert effector functions to eliminate pathogens. TRM cells are potent effector cells and as such, they are key players in focal inflammatory skin diseases. LÄS MER

  5. 9. Requirements for the Induction of Adaptive Immune Responses to Rotavirus

    Författare :Joy Nakawesi; Virusrekognition; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rotavirus; classical dendritic cells; Lymphoid organ hypertrophy; B cells; IgA; Retinoic acid; CD8 T cells; TLR3 and Poly I:C ;

    Sammanfattning : Rotavirus (RV) infections remain the leading cause of world-wide diarrhea-associated morbidity and mortality among children 200,000 deaths annually mostly in the low-income countries of Africa and Asia. Efficient clearance of the primary RV infection and protection from future re-infections is mediated by adaptive immune responses. LÄS MER

  7. 10. Influenza A virus in natural and artificial environments

    Författare :John Wahlgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Influenza is caused by influenza A virus, a single stranded RNA virus of the orthomyxoviridae family. In humans, it causes yearly outbreaks with high morbidity and excess fatality rates as a direct effect. Placed in its ecological niche however, in dabbling ducks, avian influenza virus (AIV) induce quite mild disease. LÄS MER
