  2. 6. Novel roles of ErbB3 receptor tyrosine kinase in vesicular trafficking

    Author : Ana Rosa Saez-Ibañez; Ingvar Ferby; Carl-Henrik Heldin; Johanna Ivaska; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ErbB3; Integrin; GGA3; Rabaptin5; PKD; Ack1; endocytic recycling; exosome; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

    Abstract : ErbB3 is a catalytically impaired receptor tyrosine kinase (RTK) from the EGFR family. Upon ligand binding, ErbB3 forms heterodimers with other members of the family and triggers phosphorylation cascades that promote crucial cellular functions as proliferation, differentiation and survival.

  4. 7. The role of 1-intergrins in skeletal muscle differentiation and extracellular matrix assembly

    Author : Lars Lohikangas; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; β1 Integrins; Matrix Deposition; Skeletal Muscle Cell; Biokemi; Biochemistry; Biokemi; Medical Biochemistry; medicinsk biokemi;

    Abstract : Integrin subunit β1 forms heterodimeric receptors with at least 12 different α-subunits.These integrins are the main cellular receptors for extracellular matrix and they arenecessary for normal development. In this thesis, the effects of lack of integrin subunitβ1 on matrix deposition and on skeletal muscle development were studied. READ MORE

  5. 8. Particle Transcytosis Across the Human Intestinal Epithelium : Model Development and Target Identification for Improved Drug Delivery

    Author : Elisabet Gullberg; Per Artursson; Barry Hirst; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; M-cell; FAE; Peyer´s patches; oral vaccination; uptake; endocytosis; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

    Abstract : The use of nano- and micro-particulate carriers as delivery systems for oral vaccines has been under investigation for several decades. Surprisingly little is known of their uptake in the human intestine, despite the fact that substantial improvement is required to achieve adequate immune responses in man after oral administration.

  6. 9. Integrin αVβ3-Directed Contraction by Connective Tissue Cells : Role in Control of Interstitial Fluid Pressure and Modulation by Bacterial Proteins

    Author : Åsa Lidén; Kristofer Rubin; Karl-Eric Magnusson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; interstitial fluid pressure; collagen gel contraction; integrin αVβ3; septic shock; fibronectin; Biokemi; Biochemistry; Biokemi;

    Abstract : This thesis aimed at studying mechanisms involved in control of tissue fluid homeostasis during inflammation.The interstitial fluid pressure (PIF) is of importance for control of tissue fluid balance. A lowering of PIF in vivo will result in a transport of fluid from the circulation into the tissue, leading to edema. READ MORE

  7. 10. Collagen-binding integrin α2β1 activity in vivo and in vitro : Effects of platelet-derived growth factor-BB

    Author : Karina Åhlén; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Integrin α2β1; PDGF-BB; fibroblast; interstitial fluid pressure; cytoskeletal interaction; phosphatidylinositol 3-kinase; [Ca2 ]i; Biokemi; Biochemistry; Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

    Abstract : The expression of integrins by two cell clones from a rat colon carcinoma was investigated. Cloned cells that gave rise to regressive tumors, but not cells that gave rise to progressive, lethal, tumors, adhered to interstitial collagens through the integrin α2β1, although both cell types expressed it.
