  1. 1. Tapasin - The star of the show in HLA-I maturation

    Författare :Camilla Thuring; Antigen presentation; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tapasin; HLA-I; tumor; antigen presentation;

    Sammanfattning : Human leukocyte antigen class I (HLA-I) molecules are present on the cell surface of all nucleated cells. They bind intracellular peptides and present them to the immune system thus providing a readout to cytotoxic T-cells about the status of a cell. LÄS MER

  2. 2. The quality control of MHC class I antigen presentation

    Författare :Kajsa M Paulsson; Antigen presentation; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chaperone; assembly; COPI; antigenic peptide; TAP; MHC; tapasin; Immunology; serology; transplantation; Immunologi; serologi;

    Sammanfattning : Major histocompatibility complex (MHC) class I molecules present antigenic peptides to CD8+ T cells. The peptides are generated by proteasomes in the cytosol, then translocated across the membrane of the endoplasmic reticulum (ER) by the transporter associated with antigen processing (TAP). LÄS MER

  3. 3. Dendritic cell interactions with Gram negative bacteria

    Författare :Mattias Svensson; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mycology; virology; Major histocompatibility complex molecules; Dendritic cells; Gram negative bacteria; Antigen processing; Antigen presentation; bacteriology; Microbiology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : The interaction between murine bone marrow-derived dendritic cells (DC) and the Gram negative bacteria Salmonella typhimurium and Escherichia coli have been characterised. These studies showed that DC phagocytosed and processed S. typhimurium and E. LÄS MER

  4. 4. Studying the influence of the physicochemical properties of lipid nanoparticles for mucosal vaccine delivery

    Författare :Karin Norling; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; influenza; nanoparticles; CTA1-DD; liposomes; dendritic cells; lipodisks; antigen presentation; flow cytometry; vaccine carriers; TIRF microscopy;

    Sammanfattning : Lipid-based nanoparticles have attracted attention as promising pharmaceutical carriers. Reports of them having inherent adjuvant properties make them particularly interesting as vaccine vectors; however, the physicochemical profile of an ideal nanoparticle for mucosal vaccine delivery remains unknown.

  5. 5. Processing and presentation of exogenous antigen by dendritic cells

    Författare :Liying Chen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :DC; vesicular MHC-I processing; Adenosine; CD 1 d; TACA;

    Sammanfattning : Dendritic cells (DC) play a key role in the immune system. In this thesis, we have investigated and characterized pathways for the processing and presentation of exogenous OVA on MHC-I ("cross-presentation") and how these were influenced by the purine nucleoside Adenosine (Ado), an immune regulator that accumulates to high concentrations at sites of inflammation and tumor growth.
