  3. 12. Mechanisms influencing activation and survival of normal and malignant lymphoid cells in the testis

    Författare :Mikael von Euler; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Acute lymphoblastic leukaemia; testis; cytokines; IL-1; TGFbeta;

    Sammanfattning : Acute lymphoblastic leukaemia (ALL) is the most common childhood malignancy and the testis is the third most common site of relapse after treatment. Testicular function is regulated by pituitary hormones, but the testicular microenvironment is also locally regulated through cell-cell interactions and by paracrine factors. LÄS MER

  4. 13. Molecular and functional studies of interleukin-1a in the rat testis

    Författare :Taranum Sultana; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Interleukin-l alpha; spermatogenesis; Leydig cells; Sertoli cells; calpain I and II;

    Sammanfattning : The aim of the present study was to gain a better insight into the role of interleukin-1 alpha (IL-1 alpha) in testicular physiology. In testis, IL-1alpha acts as a paracrine mediator involved in the regulation of testicular functions. LÄS MER

  5. 14. Artificial testis to study early gonadal development and germ cell differentiation

    Författare :Ahmed Reda; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Studying the early germ cell development is of great significance, as germ cells transfer the genetic material between generations. However, in humans, this type of studies in vivo is not applicable, for obvious ethical reasons. LÄS MER

  7. 15. 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
