  1. 21. Cytokine-modulated dendritic cell immunotherapy in autoimmune diseases

    Författare :Sanjaya Bandara Adikari; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Autoimmunity is the result of failure of self-tolerance processes. When the immune system fails to differentiate self from foreign, the effector mechanisms are directed towards the individual s own tissues, and pathological autoimmune disease results. LÄS MER

  3. 22. Paracrine regulation of Sertoli cell proliferation

    Författare :Cecilia Petersen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Testis; Sertoli cell; proliferation; growth factor; proinflammatory cytokine;

    Sammanfattning : The Sertoli cell is a highly differentiated somatic cell in the seminiferous epithelium of the testis. This cell is of prime importance for both testicular development and spermatogenesis. LÄS MER

  4. 23. Autocrine and paracrine regulation of Leydig cell survival in the postnatal testis

    Författare :Eugenia Colón; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :IGFs; steroidogenesis; Leydig cells; steroidogenic acute regulatory protein StAR ; insulin; IGFBP-3; IGFBP-2 and steroidogenic enzymes;

    Sammanfattning : The primary function of testicular Leydig cells is the production of androgens that promote sexual differentiation in the fetus, secondary sexual maturation at the. time of puberty, and spermatogenesis in the adult. LÄS MER

  5. 24. Cellular immune responses in allogeneic and xenogeneic transplantation models

    Författare :Annacarin Wallgren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The introduction of immunosuppressive agents and improvements in surgical techniques and ancillary care has made allotransplantation a routine procedure. However, improvements in short-term graft survival rates have not been accompanied by a similar improvement in long-term outcome due to the process of therapy-resistant chronic allograft rejection.

  7. 25. The cell line RN33B transplanted to adult retina

    Författare :Anita Blixt Wojciechowski; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oftalmologi; host glial response; Ophtalmology; differentiation; migration; proliferation; survival; immunosuppression; RN33B; brain-derived precursor cells; retinal degeneration; subretinal transplantation;

    Sammanfattning : The thesis describes the neural precursor cell line RN33B transplanted subretinally to adult healthy and young dystrophic rat retina. The cell line is generated from E12,5 rat raphe nucleus and transduced with the temperature sensitive mutant of the Simian Virus 40 (SV40) large T-antigen. LÄS MER
