  1. 1. On the origin of B cells. Elucidating the Role of Tyrosine Kinase Receptors in B Cell Development

    Författare :Alya Zriwil; Avdelningen för molekylär hematologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoiesis; B cell development; cytokine; tyrosine kinase receptors;

    Sammanfattning : B cells are essential cells that are part of the adaptive immune system with the capacity to produce antibodies against exogenous antigens. These cells are produced through a process called hematopoiesis, tightly regulated by extrinsic and intrinsic factors. LÄS MER

  3. 2. Cytokines and their soluble receptors in nasal fluids from school children with allergic rhinitis

    Författare :Mikael Benson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Allergic rhinitis; school children; cytokines; soluble cytokine receptors; nasal fluids;

    Sammanfattning : Allergic inflammation is associated with a shift in the balance between cytokines produced by two T helper subsets (Th1 and Th2) towards a preponderance of Th2 cells. Interleukin (IL)-4 is produced by Th2 cells and interferon-g (IFN-g) by Th1 cells. The ratio IL-4/IFN-g is often used as a marker of the balance between the cytokines. LÄS MER

  4. 3. Hematopoiesis, Kazal Inhibitors and Crustins in a Crustacean

    Författare :Young-A Kim; Kenneth Soderhall; Irene Soderhall; Shun-ichiro Kawabata; Uppsala universitet; []
    Nyckelord :Biochemistry; innate immunity; cytokine; hematopoietic tissue; ATP synthase β subunit; Kazal; antibacterial peptides; Biokemi;

    Sammanfattning : Hemocytes are important as storage and producers of proteins of the innate immune defence, as well as actors of the cellular immune response. Therefore the hematopoietic process is critical for survival of most invertebrates. LÄS MER

  5. 4. Cyclooxygenase activity and tumor progression

    Författare :Christian Cahlin; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cyclooxugenase; PGE2; inflammation; cytokine; nitric oxide; indomethacin; IL-6;

    Sammanfattning : Invasive growth of malignant tumors is associated with local and systemic inflammation, which may promote progression and metastases. Inflammation is also responsible for appearing manifestations of advanced cancer as fatigue, anorexia and wasting with eicosanoids, proinflammatory cytokines and nitric oxide as mediators. LÄS MER

  7. 5. Immune cells in pregnant uterine mucosa : functional properties, cellular composition and tissue organization

    Författare :Lucia Mincheva-Nilsson; Sten Hammarström; Rolf Kiessling; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; immunologically privileged site; TCR γδ cells; CD56 cells; large granular lymphocytes; immunosuppression; cytokine; interleukin; lymphoid cell cluster; intraepithelial lymphocytes; glandular epithelium; immuno electron microscopy; pregnancy; decidua; lactoferrin; lactoferrin receptor; colostrum;

    Sammanfattning : The pregnant uterus mucosa - decidua - is an "immunologically privileged" site. A semiallogeneic embryo is allowed to survive, develop, and grow while the same tissue implanted outside the uterus will be rejected. The decidua basalis, which participates in the placenta formation, is a tissue rich in lymphoid cells. LÄS MER
