  2. 1. Adhesion Dependent Signals : Cell Survival, Receptor Crosstalk and Mechanostimulation

    Author : Anjum Riaz; Staffan Johansson; Bengt Hallberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Integrins; Signal transduction; Protein kinase B; Akt; PI3K; Heparanase; ROS; Mechanosignalling; Molekylär cellbiologi; Molecular Cellbiology; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi; Cellforskning; Cell Research;

    Abstract : The integrin family of cell surface receptors is evolutionary conserved and found in all multicellular animals. In humans 8-alpha and 18-beta integrins are non-covalently associated into 24 dimers. Integrins mediate cell-extracellular matrix and cell-cell interactions and participate in cell signalling.

  4. 2. Consequences of Shb Deficiency on Hematopoietic Cell Function

    Author : Karin Gustafsson; Michael Welsh; Martin Bergö; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hematopoiesis; hematopoietic stem cells; myeloid neoplasia; T cells; atopic dermatitis; cell signaling; Medical Cell Biology; Medicinsk cellbiologi;

    Abstract : The adaptor protein Shb has been implicated in the signaling of several tyrosine kinase receptors and previous studies have suggested a role for Shb in the signal transduction of T cells. Shb associates with the T cell receptor (TCR) and partakes in the signal propagation of activated T lymphocytes. READ MORE

  5. 3. Integrin Signaling in Cell Adhesion and Mechanotransduction : Regulation of PI3K, AKT, and ROS

    Author : Kathrin Stephanie Zeller; Staffan Johansson; Kristofer Rubin; John Couchman; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; integrin; ROS; PI3K; AKT; mechanosignaling; actin polymerization; spreading;

    Abstract : Integrins are a family of conserved cell surface receptors found throughout the animal kingdom. They comprise 24 dimers in mammals, and regulate a number of processes including cell survival, differentiation, and migration. READ MORE

  6. 4. Study of the Proliferation, Function and Death of Insulin-Producing Beta-Cells in vitro: Role of the Transcription Factor ZBED6

    Author : Xuan Wang; Nils Welsh; Nils Billestrup; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ZBED6; Pancreatic beta-cell; Proliferation; Insulin secretion; Apoptosis; Adhesion; Medical Science; Medicinsk vetenskap;

    Abstract : A thorough understanding of beta-cell proliferation, function, death and regeneration under normal condition as well as in the progression of diabetes is crucial to the conquest of this disease. The work presented in this thesis aimed to investigate the expression and role of a novel transcription factor, Zinc finger BED domain-containing protein 6 (ZBED6), in beta-cells. READ MORE

  7. 5. Helicobacter spp. interactions with mucins: adhesion and mucin regulation of pathogen proliferation and gene expression

    Author : Emma C Skoog; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter; mucin; glycosylation; Lactobacillus; adhesion; proliferation; gene expression; CagA; SabA; BabA; ArsS; Fur;

    Abstract : Helicobacter pylori colonizes the gastric mucosa of approximately half of the world’s population and is a risk factor for gastritis, peptic ulcers and gastric cancer. H. pylori is surrounded by, and adheres to, the heavily glycosylated mucins that build up the mucus layer. The carbohydrate structures on the mucins that act as ligands for H. READ MORE
