  4. 42. Immunomodulation during human pregnancy : placental exosomes as vehicles of immune suppression

    Author : Ann-Christin Stenqvist; Lucia Mincheva-Nilsson; Maria Jenmalm; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; exosomes; microvesicles; pregnancy; placenta; syncytiotrophoblast; immune privilege; apoptosis; cytotoxicity; T regulatory cells; NKG2D; MICA B; FasL; TRAIL; immunologi; Immunology;

    Abstract : The mammalian pregnancy comprises a challenge to the maternal immune system since the fetus is semi-allogeneic and could thus be rejected. Pregnancy success is associated with the placenta that is not only essential for oxygen supply, nourishment and pregnancy hormones but also plays a role in the protection of the fetus against maternal immunologic attack.

  5. 43. Investigations of Hematopoietic Stem Cells and Their Age-Associated Alterations

    Author : Alexandra Rundberg Nilsson; Avdelningen för molekylär hematologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic stem cells; Aging; Serial transplantation; Self-renewal; Flow cytometry; Gene expression;

    Abstract : The hematopoietic stem cell (HSC) has and continues to be extensively investigated, and represents by far the most studied somatic stem cell. Development of various experimental technologies, including fluorescence activated cell sorting (FACS), have been crucial for research advancements within the hematopoietic field. READ MORE

  6. 44. New sensitive and specific methods for sex steroid measurements in rodent serum and tissues

    Author : Maria E. Nilsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sex steroids; mass spectrometry; rodents;

    Abstract : Accurate measurement of sex steroids (androgens, estrogens, and progesterone) is essential in research and clinical settings for common diseases including osteoporosis, prostate cancer, breast cancer, and cardiovascular diseases. Sex steroids are not only produced in the gonads and adrenals but may also be locally synthesized in peripheral target tissues. READ MORE
