  1. 6. Translational regulation of genes in salmonella typhimurium by vitamin B12

    Författare :Solveig Ravnum; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Transational Control; Salmonella typhimurium; Vitamin B12; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; mikrobiologi; Microbiology;

    Sammanfattning : In this thesis I have studied the mechanism by which vitamin B12 regulates the expression of the cob operon and the btuB gene in Salmonella typhimurium. The cob operon encodes most of the 25 genes required for the de novo synthesis of vitamin B12, and the butB gene encodes the outer membrane protein needed for transport of exogenous vitamin B12 into the cell.

  3. 7. Mechanisms of immune escape : implications for immunotherapy against cancer

    Författare :Karl-Johan Malmberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Tumor Immunology; Immune escape; NK receptors; T lymphocytes; Oxidative stress; Vitamin E;

    Sammanfattning : Tumor cells can be recognized and killed by cytotoxic T cells specific for certain tumor antigens. Immune mediated selection pressure along with genetic instability of tumor cells result in a growth advantage of tumor cells that acquire a less immunogenic phenotype. LÄS MER

  4. 8. Vehicle-in-the-loop validation of autonomous cars

    Författare :Angel Molina Acosta; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; backward reachability; scenario-based testing; multi-agent systems; Model Predictive Control;

    Sammanfattning : Validation of autonomous driving (AD) cars is a difficult task because of the complexity that results from the integration of multiple systems and the variety of operating conditions. To this end, testing with real vehicles is crucial to ensure a thorough validation of AD cars. LÄS MER

  5. 9. Dust mite allergens : cloning, characterisation and T-cell responses

    Författare :Tove L J Eriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The number of allergens that have been cloned has increased dramatically during the last 10 years, and today, over 400 allergen sequences are available in the databases. In addition, at least 15 dust mite allergens have been characterised. LÄS MER

  7. 10. The Multifunctional Nature of the Adenovirus L4-22K Protein

    Författare :Susan Lan; Göran Akusjärvi; Per Elias; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; L4-22K; MLP; RNA; transcription; splicing; adenovirus;

    Sammanfattning : The adenovirus major late transcription unit (MLTU) encodes for most of the mRNAs that are translated into the structural proteins of the virus capsid. Transcription from the MLTU is directed by the major late promoter (MLP), which is highly activated during the late phase of infection. LÄS MER
