  1. 1. Modulation of B cell access to antigen by passively administered antibodies an explanation for antibody feedback regulation?

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Hui Xu; Uppsala universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IgG; IgG3; IgE; suppression; enhancement; epitope masking; antigen transport; antigen presentation; follicular B cells; marginal zone B cells; Immunologi; Immunology;

    Sammanfattning : Antibody responses can be up- or down-regulated by passive administration of specific antibody together with antigen. Depending on the structure of the antigen and the antibody isotype, responses can be completely suppressed or enhanced up to a 1000-fold of what is seen in animals immunized with antigen alone.

  2. 2. Dendritic cell presentation of type II collagen

    Detta är en avhandling från Department of Laboratory Medicine, Lund University

    Författare :Meirav Holmdahl; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; chromosome 2; arthritis; proteases; antigen presentation; Dendritic cell; type II collagen;

    Sammanfattning : Type II collagen (CII) is the main protein component of cartilage and immune recognition of CII plays a critical role for the development of collagen induced arthritis (CIA), a widely used animal model for rheumatoid arthritis (RA). Antigen presentation is an important requirement for the immune response, the more efficient presentation of the antigen the better tolerance will be induced and thereby protect against arthritis.

  3. 3. Antigen presentation by dendritic cells and immunomodulation by cholera toxin B subunit. Implications for vaccine development

    Detta är en avhandling från Göteborg

    Författare :Annie George-Chandy; Göteborgs universitet.; Gothenburg University.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dendritic cells; cholera toxin B subunit; antigen-presentation;

    Sammanfattning : Antigen presentation by dendritic cells is the first event that takes place upon initiation of an acquired immune response. The inductive events during antigen presentation will essentially govern the orientation and the magnitude of the subsequent immune responses. LÄS MER

  4. 4. Dendritic cell interactions with Gram negative bacteria

    Detta är en avhandling från Mattias Svensson, Sölvegatan 19, 223 62 Lund

    Författare :Mattias Svensson; [2000]
    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

  5. 5. Feedback Enhancement of Immune Responses by IgE, IgM, and IgG3 Antibodies

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Zhoujie Ding; Uppsala universitet.; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IgE; IgM; IgG3; antibody responses; T-cell responses; antigen transportation; antigen presentation; complement; complement receptors 1 and 2; Immunologi; Immunology;

    Sammanfattning : Antibodies can enhance or suppress the immune responses against their specific antigens. This phenomenon is known as antibody-mediated feedback regulation. We have studied the mechanisms underlying IgE-, IgM-, and IgG3-mediated enhancement of immune responses in mouse models using intravenous immunization. LÄS MER
