  1. 16. Global Profiling of Host Cell Gene Expression During Adenovirus Infection

    Författare :Fredrik Granberg; Hongxing Zhao; Ulf Pettersson; Richard Roberts; Uppsala universitet; []
    Nyckelord :Genetic engineering; Adenovirus; Microarray; Gene expression; Host-virus interaction; Genteknik;

    Sammanfattning : To investigate mechanisms involved in virus-host interactions, global changes in host gene expression were examined during infection with adenovirus type 2 (Ad2) using cDNA microarray technology. In paper I and II, transcriptional changes in HeLa cells were investigated during the early and late phase of infection, respectively. LÄS MER

  3. 17. Role of birds in the biology of Lyme disease Borrelia

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lyme disease; birds; Borrelia; I. uriae; infection reactivation; stress; bipolar distribution; transequatorial transport;

    Sammanfattning : Lyme disease is a tick-transmitted illness caused by Borrelia burgdorferi sensu lato (s.l.), a group of spirochetes with at least three human pathogenic species, B. burgdorferi sensu stricto, B. LÄS MER

  4. 18. Response mechanisms of normal hematopoietic cells and leukemic cells to genotoxic agents and novel therapeutic strategies

    Författare :Andreas Hedblom; Malmö Experimentell cancerforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic stem cells; genotoxic damage; cell cycle; leukemia; heme oxygenase; differentiation;

    Sammanfattning : Hematopoiesis is initiated by a rare population of hematopoietic stem cells (HSC) in the bone marrow (BM). HSCs give rise to red blood cells and white blood cells of myeloid and lymphoid lineages. LÄS MER

  5. 19. Unique Solutions to Universal Problems : Studies of the Archaeal Cell

    Författare :Erik A. Pelve; Rolf Bernander; Sonja Verena Albers; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Archaea; Cdv; Cell cycle; Cell division; Cell lysis; Crenarchaea; ESCRT-III; Flow cytometry; Microarray; Microscopy; Nitrosopumilus; SIRV2; Sulfolobus; Thaumarchaea; Transcription; VAP; Virus; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

    Sammanfattning : Archaea is one of the three domains of life and studies of archaeal biology are important for understanding of life in extreme environments, fundamental biogeochemical processes, the origin of life, the eukaryotic cell and their own, unique biology. This thesis presents four studies of the archaeal cell, using the extremophilic Sulfolobus and ocean living Nitrosopumilus as model systems. LÄS MER

  7. 20. Remodelling of the cellular environment in Epstein-Barr virus infection

    Författare :Simone Callegari; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : For successful infection viruses modify the host cell environment by transcriptional, posttranscriptional or post-translational regulation of cellular signaling pathways. In the work described in this thesis bioinformatics analysis coupled with biochemical validations were used to dissect critical features of these viral strategies in the context of infection by Epstein–Barr virus (EBV), a human herpesvirus associated with lymphoid and epithelial cell tumors.
