  1. 6. Interactions of satellite phage P4 with its helpers : P2 and WΦ phages

    Författare :Liu Tao; Karin Hammer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Genetics; genetik;

    Sammanfattning : Bacteriophage P4 is a defective phage that needs a helper phage to grow lytically, since it lacks structural genes and genes encoding host cell lysis functions. P4 has the capacity to derepress the unrelated prophage P2, or its relatives after infection, thereby getting access to the late functions of the helper. LÄS MER

  3. 7. Prion processing and propagation in neuronal and dendritic cell culture models

    Författare :Katarina M Luhr; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Prion; scrapie; cathepsin; processing; IFN-gamma; DRG; dendritic cell; cytokine;

    Sammanfattning : Prion diseases are rare neurodegenerative diseases, associated with a conversion of a normal cellular protein, PrPC, into its misfolded and partial protease resistant isoform, PrPSc. These diseases affect both animals and humans and are unique since they can not only be genetic and sporadic, but also transmissible. LÄS MER

  4. 8. Vascular Endothelial Growth Factor (VEGF) and Peripheral Nerve Regeneration

    Författare :Mariann Sondell; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Schwann cell; SCG; rat; peripheral nerve regeneration; neuropilin-1; nerve repair; mouse; growth factor; flk-1; axonal outgrowth; DRG; VEGF; Animal physiology; Djurfysiologi;

    Sammanfattning : This thesis concerns vascular endothelial growth factor (VEGF) and its possible role as a neurotrophic factor. I have investigated the effect of VEGF on neurons in culture but also in vivo, following a crush lesion of the sciatic nerve, and following nerve repair. LÄS MER

  5. 9. Reaction and Diffusion Phenomena in Biomimetic Nanoscale Reactors and Networks

    Författare :Kristin Sott; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; artificial cell; restricted geometries.; enzymatic reactions; micromanipulation; biomimetic; nanotubes; diffusion; Vesicles; networks; liposomes;

    Sammanfattning : Methods for construction of geometrically complex, fully connected surface-immobilized microscopic networks of phospholipid bilayer vesicles (1-50 µm in diameter) interconnected by lipid nanotubes (100-300 nm in diameter), have been developed. The networks have controlled connectivity and are well-defined with regard to the container size, content, angle between nanotube extensions, and nanotube length. LÄS MER

  7. 10. Contracting muscle for regeneration : myogenic dedifferentiation in limb progenitor cell formation

    Författare :Sara Lööf; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The urodele amphibians, such as newts and axolotls, are unique among vertebrates since they regenerate their limbs, tail, jaws and part of their heart and CNS as adults. After amputation of a newt limb, regeneration proceeds by the reversal of differentiation of tissues in the limb stump. LÄS MER
