  1. 1. Immunomodulation during human pregnancy placental exosomes as vehicles of immune suppression

    University dissertation from Umeå : Umeå Universitet

    Author : Ann-Christin Stenqvist; Umeå universitet.; [2014]
    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.

  2. 2. Regenerative effects of mesenchymal stem cell-derived exosomes

    University dissertation from Göteborgs universitet

    Author : Xiaoqin Wang; Göteborgs universitet.; Gothenburg University.; [2019]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; aging; cell adhesion; cell-material interaction; exosomes; extracellular vesicles; mesenchymal stem cells; osteogenic differentiation; proliferation; regeneration; titanium;

    Abstract : Mesenchymal stem cells (MSCs) play pivotal roles for bone regeneration by virtue of their osteogenic differentiation ability and immunomodulatory capacity. Recently, secretion of exosomes/extracellular vesicles (EVs) has been suggested as a new mechanism of MSC-based therapy. READ MORE

  3. 3. Immune modulation in serous epithelial ovarian cancer focus on the role of tumor-derived exosomes

    University dissertation from Umeå : Umea University

    Author : Alireza Labani Motlagh; Umeå universitet.; [2017]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ovarian cancer; EOC; HGSC; exosomes; NKG2D; MICA B; ULBP; DNAM-1; PVR; nectin-2; lncRNAs; immune suppression; anti-tumor immunity; NK-cell cytotoxicity; cytokines; Th1; Th2; T regulatory response; inflammation; tumor microenvironment;

    Abstract : Serous epithelial ovarian cancer (EOC) is a potent suppressor of the immune defense. Here, we studied interactions between EOC and the immune system that lead to escape from tumor immune surveillance. READ MORE

  5. 5. Physical characterization of exosomes and other extracellular vesicles using surface-based sensing

    University dissertation from Göteborg : University of Gothenburg

    Author : Deborah Rupert; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nanoparticle tracking analysis; exosomes; scattering; surface-based biosensing; optical density; cluster of differentiation 63 CD63 ; liposomes; label-free; fluorescence; surface plasmon resonance; Extracellular vesicles; specificity; antibody; lipid content; single particle; quantification; size distribution; optical waveguide microscopy;

    Abstract : Extracellular vesicles (EVs) are hundred of nanometer sized particles secreted by almost all cell types. Exosomes are one type of EVs today intensively investigated due to the increased evidence suggesting that they play important roles as communicating vehicles in a broad range of physiological processes, pathological conditions and disease diagnostics.
