  1. 21. Alphavirus vectors as recombinant vaccines

    Författare :Peter Berglund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Semliki Forest virus; Alphavirus; Synthetic vaccmes; Influenza A virus; HIV-I; SIV; DNA vaccines; AIDS vaccines; Influenza vaccine;

    Sammanfattning : This thesis describes further developments of an expression system based on the alphavirus Semliki Forest virus (SFV), and its potential use as recombinant vaccine. The RNA genome of SFV contains a 3'open reading frame (ORF) encoding the structural proteins, and a 5' ORF coding for the viral replicase. LÄS MER

  3. 22. Developmental role and ligand binding properties of macrophage scavenger receptor MARCO

    Författare :Yunying Chen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Macrophages express several cell surface receptors, that mediate the recognition of a wide range of endogenous and exogenous ligands. In this manner, macrophages are able to perform their multiple biological functions in regulation of homeostasis and host defense. LÄS MER

  4. 23. Expression and function of thyroid hormone receptor alpha 1 in the brain

    Författare :Karin Wallis; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Thyroid hormone is fundamentally important for development and maintenance of adult brain functions and maternal hypothyroxinemia during pregnancy can lead to a severe mental retardation known as endemic cretinism. The first realization that endemic cretinism is caused by iodine deficiency and its association with thyroid hormone was made a century ago; this eventually resulted in dietary supplementation programme, e.

  5. 24. Conditional targeting of the PDGF-B gene

    Författare :Maria Enge; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gene targeting; Cre loxP; PDGF; pericytes; diabetic retinopathy; brain injury; neurons;

    Sammanfattning : Platelet derived growth factors (PDGF) are known as mitogens for fibroblasts, smooth muscle cells (SMC) and glia cells in culture. Previous in vivo analyses have shown that PDGF-B is necessary for normal embryonic development and life after birth, but the relative importance of the various cellular sources of PDGF-B during development has not been clarified.

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

    Författare :Zhoujie Ding; Birgitta Heyman; Eva Severinson; Uppsala universitet; []
    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
