  1. 1. Dendritic cells in cancer immunotherapy

    Författare :Karin Gustafsson; Göteborgs universitet; []
    Nyckelord :vaccines; dendritic cells; αDC1; PGE2DC; natural killer cells; T cells;

    Sammanfattning : Dendritic cells (DCs) play a central role in the initiation and regulation of innate and adaptive immune responses and have increasingly been applied as vaccines for cancer patients. Ex vivo generation and antigen loading of monocyte-derived DCs allows a controlled maturation, with the aim of imprinting different DC functions that are essential for their subsequent induction of a T cell-mediated anti-tumor response.

  3. 2. Pathogenic Neisseria infections of human neutrophils and epithelial cells : focusing on host responses and immune evasion

    Författare :Niklas Söderholm; Helena Aro; Thomas Rudel; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neisseria meningitidis; Neisseria gonorrhoeae; Neutrophils; PMN; Epithelial cells; Polarized cells; Type IV pili; Adherence; Cell cycle; DNA damage; Lactobacillus; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : N. meningitidis and N. gonorrhoeae are obligate human pathogens that colonize mucosal surfaces and are often carried asymptomatically. These bacteria have developed adhesive structures that promote adherence to host cells and efficient colonization of new hosts. LÄS MER

  4. 3. Cancer Immunotherapy : Oncolytic viruses and CAR-T cells

    Författare :Jing Ma; Di Yu; Magnus Essand; Mia Phillipson; Mohanraj Ramachandran; Karl-Johan Malmberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer immunotherapy; Oncolytic viruses; chimeric antigen receptor CAR -T cells; Helicobacter pylori Neutrophil Activating Protein;

    Sammanfattning : Various forms of cancer immunotherapy have developed rapidly with improved survival and quality of life for cancer patients. Cancer immunotherapy aims to educate the patient’s immune system to eliminate cancer cells, including immune checkpoint inhibitors (ICIs), adoptive cell transfer (mostly T cells), oncolytic viruses (OVs) and cancer vaccines.

  5. 4. New Electrochemical Tools to Study Exocytosis

    Författare :Joakim Wigström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; amperometry; QCM-D; micro electrode array; large dense core vesicles; chromaffin cells; PC-12 cells; microelectrode; exocytosis; electrochemical cytometry; electrochemical imaging; acetylcholine; endocytosis; nanoparticles; enzyme biosensor; microfabrication;

    Sammanfattning : The work described in this thesis has the focus on the development of new analytical tools to study processes related to cellular secretion (exocytosis) in cell models. Four novel techniques were developed, allowing new ways to study processes related to exocytosis, and gain previously unattainable knowledge. LÄS MER

  7. 5. Human intestinal epithelial cells in innate immunity : interactions with normal microbiota and pathogenic bacteria

    Författare :Gangwei Ou; Sten Hammarström; Marie-Louise Hammarström; Agnes Wold; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; immunologi; Immunology;

    Sammanfattning : Rod-shaped bacteria were previously shown to be associated with the small intestinal epithelium of children with celiac disease (CD). Using culture-dependent and independent methods, we characterized the microbiota of small intestine in children with CD and controls. The normal microbiota constitutes an unique organ-specific biofilm. LÄS MER
