  1. 11. Water Fluxes and Cell Migration : How Aquaporin 9 Controls Cell Shape and Motility

    Författare :Thommie Karlsson; Karl-Eric Magnusson; Roger Karlsson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Prerequisites for all modes of cell migration are cell-substratum interactions that require a sophisticated interplay of membrane dynamics and cytoskeletal rearrangement. Generally, a migrating cell is polarized with a distinct rear and front, from which it extends a wide and thin membrane protrusion- lamellipodium, small fingerlike projections- filopodia, and membrane blisters- blebs.

  3. 12. Modeling and Data Analysis in Cellular Biophysics

    Författare :Jacob Kowalewski; Hjalmar Brismar; Anita Aperia; Björn Önfelt; Karl-Eric Magnusson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biophysics; Biofysik;

    Sammanfattning : Cellular biophysics deals with the physical aspects of cell biology. This thesis presents a number of studies where mathematical models and data analysis can increase our understanding of this field. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 14. Towards a Refined Model of Neutrophil Motility

    Författare :Vesa-Matti Loitto; Karl-Eric Magnusson; Tommy Andersson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human polymorphonuclear leukocytes. PMNL; neutrophils; neutrophil motility; N-formyl-Met-Leu-Phe; Medical microbiology; Medicinsk mikrobiologi;

    Sammanfattning : The ability of human polymorphonuclear leukocytes (PMNL; neutrophils), to sense and move to sites of infection is essential for our defense against pathogens. Cell motility is critically dependent on a dynamic remodeling of morphology. LÄS MER

  7. 15. Mechanisms involved in macrophage phagocytosis of apoptotic cells

    Författare :Anna Nilsson; Per-Arne Oldenborg; Karl-Eric Magnusson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; macrophages; dendritic cells; phagocytosis; apoptotic cells; senescent erythrocytes; CD47; SIRPalpha; LRP1; calreticulin; Immunology; Immunologi; immunologi; Immunology;

    Sammanfattning : Efficient removal of apoptotic cells is critical for development, tissue remodelling, maintenance of homeostasis, and response to injury. Phagocytosis of apoptotic cells is mediated by many phagocytic receptors, soluble bridging molecules, and pro-phagocytic ligands on the surface of apoptotic cells. LÄS MER
