  1. 11. Maternal microchimerism

    Författare :Anna Maria Kanold; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Microchimerism refers to one individual harboring cells or DNA at a low level that derive from another individual. The most common source is pregnancy when cells from the fetus and the mother pass the placenta bidirectionally, and give rise to maternal microchimerism (cells from the mother in the fetus) and fetal microchimerism (cells from the fetus in the mother).

  3. 12. Mechanisms of immune escape : implications for immunotherapy against cancer

    Författare :Karl-Johan Malmberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Tumor Immunology; Immune escape; NK receptors; T lymphocytes; Oxidative stress; Vitamin E;

    Sammanfattning : Tumor cells can be recognized and killed by cytotoxic T cells specific for certain tumor antigens. Immune mediated selection pressure along with genetic instability of tumor cells result in a growth advantage of tumor cells that acquire a less immunogenic phenotype. LÄS MER

    Författare :Leif Skamris Matthiesen; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The maternal systemic immune response during pregnancy is only fragmentarily understood. An adequate immune response to the gestational product is of vital importance for a successful pregnancy. LÄS MER

  7. 15. Study of serotonin, innervation and sensory neuropeptides in allergic contact dermatitis

    Författare :Husameldin El-Nour; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Allergic contact dermatitis; serotonin; sensory neuropeptides; nerve density;

    Sammanfattning : In a murine model of contact allergy, 24 h after challenge with antigen, increased axonal growth using an antibody to growth-associated protein-43 (GAP-43) was seen in the epidermis and dermis of eczematous skin. Protein gene product 9.5 (PGP 9.5) positive nerve fibres tended to increase in the eczematous skin. LÄS MER
