  1. 6. Breast-feeding, nasopharyngeal colonization and otitis media

    Författare :Gustaf Aniansson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cleft palate.; URI; SOM; AOM; otitis media; H. influenzae; S. pneumoniae; Breast-feeding; nasopharyngeal colonization; Immunology; serology; transplantation; Immunologi; serologi;

    Sammanfattning : This thesis analyzed the relationship between breastfeeding, nasopharyngeal colonization and acute otitis media (AOM) in children. Nasopharyngeal cultures were collected from 400 children and milk samples from their mothers in connection with the scheduled visits to well baby clinics at 1-3, 4-7 and 8-12 months of age, and episodes of AOM and URI were documented.

  3. 7. Studies of penta-decameric binding proteins: AP-4 and CBF-A

    Författare :Alaitz Aranburu; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; transplantation; Metabolism; serologi; metabolism; Biokemi; serology; Immunology; hnRNP H; NPM; CBF-A; AP-4; transcription; B cells; immunoglobulin; Immunologi;

    Sammanfattning : Each immunoglobulin (Ig) V gene segment contains an upstream promoter region. The octamer element and the TATA box are the only elements that are conserved in all Ig promoters. The presence of the octamer element is necessary, but not sufficient to support high levels of transcription. LÄS MER

  4. 8. B cell activation in vitro: thymus-dependent immune responses and bacterial cell surface proteins

    Författare :Karol Axcrona; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nuclear transport; bacterial Ig-binding proteins; CD40L promoter; CD21; Ig; B lymphocyte activation in vitro; CD40; Immunology; serology; transplantation; Immunologi; serologi;

    Sammanfattning : In this thesis aspects of peripheral B lymphocyte differentiation were studied. Through in vitro experiments, B lymphocyte activation was assessed. B lymphocytes express immunoglobulin (Ig) specific for a certain antigen on the cell surface, and when surface Ig is crosslinked by an antigen, the cell is activated. LÄS MER

  5. 9. Nitric Oxide Regulation during Anti-tumor Immunotherapy

    Författare :Wiaam Badn; Neurokirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transplantation; Immunologi; serology; Immunology; Medicin människa och djur ; immunotherapy; Medicine human and vertebrates ; immunosuppression; PGE2; Nitric oxide; serologi;

    Sammanfattning : During tumor progression a strong immunosuppression is developed and is believed to be the major reason why immunotherapy fails. This suppression is induced in response to factors produced from tumor cells, but can also be induced after immunotherapy. LÄS MER

  7. 10. Role of collagen type II specific antibodies in arthritis

    Författare :Estelle Bajtner; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serologi; transplantation; serology; Immunology; tolerance; collagen type II; CIA; B cell epitope; antibody; arthritis; Immunologi;

    Sammanfattning : Rheumatoid arthritis (RA) is a chronic inflammatory disease resulting in destruction of cartilage and bone. The role of the B cells in RA pathogenesis clearly involves autoantibodies. Collagen type II (CII)-specific antibodies have been identified in RA synovium and synovial fluid. LÄS MER
