  2. 21. Molecular characterisation of major allergens from mite (Lep d 2) and cat (Fel d 1)

    Author : Liselotte Kaiser; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Allergens allergy; cat; mite; immunotherapy; recombinant allergens.;

    Abstract : The prevalence of allergic disease has increased significantly during the last decades and today more than 30% of the Swedish population is affected. By using recombinant allergens, diagnostics and treatment can be improved and the mechanisms of allergic reactions may be further explored. READ MORE

  4. 22. Epstein-Barr virus latency in transplant patients and healthy carriers

    Author : Jie-Zhi Zou; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : In this thesis, I studied the latency situation of Epstein-Barr virus (EBV) in bone marrow transplanted (BMT) patients and healthy virus carriers. Paper 1: Epstein-Barr virus genomes are found predominantly in lgA-positive B cells in the blood of healthy carriers. READ MORE

  5. 23. Human T-lymphocyte activation : interactions between lymphocytes and mitogenic or non-mitogenic lectins

    Author : Marie-Louise Dillner-Centerlind; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The aim of this investigation was to gain further insights in the mechanisms of T-lymphocyte activation by lectins. Interactions between the lectins and purified lymphocytes from human peripheral blood, were studied in the following respects: in vitro culture requirements for lectin induced DNA-synthesis, intercellular regulations of the mitogen response and binding of lectins to lymphocyte surface components.

  6. 24. Exosomes in immune regulation and allergy

    Author : Charlotte Admyre; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Exosomes are nano-sized vesicles of endosomal origin which are secreted from several different cell types. Depending on their cellular source they have been suggested to have different functions, like having a role in antigen delivery and T cell activation (antigen presenting cell-derived exosomes) or a role in tolerance induction (epithelial cell-derived exosomes).

  7. 25. Mechanisms of immune escape in EBV associated malignancies : Hodgkin's disease and Burkitt's lymphoma

    Author : Teresa Frisan; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Epstein-Barr virus; tumor immune escape; antigen presentation; cytotoxic T lymphocytes;

    Abstract : The work presented in this thesis is focused on the analysis of the mechanisms operating in the immune escape of two Epstein-Barr virus (EBV) associated tumors: Hodgkin's Disease (HD) and Burkitt's lymphoma (BL). EBV positive HD tumor cells express at least 3 viral proteins: the EBV nuclear antigen (EBNA)1, the latent membrane proteins (LMP)1 and LMP2A. READ MORE
