  1. 1. RhoGTPase Signaling in Cell Polarity and Gene Regulation

    Författare :Ann-Sofi Johansson; Pontus Aspenström; Johan Lennartsson; Christer Larsson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; RhoGTPase; Par6; cell polarity; aPKC; epithelial cell; PDGF; gene regulation; microarray; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

    Sammanfattning : RhoGTPases are proteins working as molecular switches as they bind and hydrolyze GTP. They are in their active conformation when GTP is bound and are then able to interact with their effector proteins, which relay the downstream signaling. When the GTP is hydrolyzed to GDP, the RhoGTPase is inactivated. LÄS MER

  2. 2. Roles of mammalian Scribble in polarity signaling, virus offense and cell-fate determination

    Författare :Michael Wigerius; Magnus Johansson; Lawrence Banks; Stockholms universitet; []

    Sammanfattning : Mammalian Scribble is a target for proteins encoded by human papilloma virus, retro- and flaviviruses. Tick-borne encephalitis virus (TBEV) is a flavivirus that have evolved distinct strategies to escape antiviral responses. LÄS MER

  3. 3. A Podocyte view on RhoGTPases and actin cytoskeleton regulation

    Författare :Lovisa Bergwall; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Podocyte; RhoGTPases; Actin cytoskeleton regulation;

    Sammanfattning : Proteinuria is a hallmark symptom of chronic kidney disease, that if left to persist constitutes a risk for progression of disease. Symptomatic treatment aiming at decreasing proteinuria is therefore standard practice. LÄS MER

  4. 4. Role of Wnt-5a in breast cancer

    Författare :Janna Sand-Dejmek; Malmö Experimentell patologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; General pathology; signal transduction; metastasis; adhesion; breast cancer; Syk; Wnt-5a; DDR1; pathological anatomy; Patologi allmän ; patologisk anatomi;

    Sammanfattning : Breast cancer is one of the most common cancer forms in the industrialized world. Only in Sweden, nearly 6000 women are diagnosed with breast cancer each year and 1/3 of them eventually succumb to the disease. LÄS MER

  5. 5. Germinal centers - why and why not? : the humoral response in primary immunodeficiency

    Författare :Carin Dahlberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : An efficient and regulated immune system is required for protection against pathogens. B cells are required for a humoral response. For a sustained humoral response against pathogens germinal center (GC) reactions are required. In the GC reaction, B cells with antigen-specific B cell receptors are selected and expanded. LÄS MER
