  3. 2. Structural rearrangements of actins interacting with the Chaperonin systems TRiC/Prefoldin and GroEL/ES

    Författare :Laila Villebeck; Bengt-Harald Jonsson; Bente Vestergaard; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; chaperonin mechanisms; bound target protein; fluorescence resonance energy transfer FRET ; Actin; abundant eukaryotic protein; Molecular biology; Molekylärbiologi;

    Sammanfattning : The studies in this thesis are mainly focused on the effects that the chaperonin mechanisms have on a bound target protein. Earlier studies have shown that the bacterial chaperonin GroEL plays an active role in unfolding a target protein during the initial binding. LÄS MER

  4. 3. The surface complex of Euglena gracilis. Involvement in cellular movements and biochemical and molecular analyses of the components

    Författare :Silja K Petersen-Mahrt; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; UV-B radiation; tubulin; surface complex; plasma membrane; phylogeny; phototaxis; nitrogen deficiency; membrane skeleton; Euglena gracilis; actin; cell shape; Physiological biophysics; Växtfysiologi;

    Sammanfattning : The flagellate Euglena gracilis shows rhythms in phototaxis and cell shape changes between oblong and round. Artificial UV-B radiation of 0.5 W m-2 caused a loss in phototaxis, but the peak of activity occurred at the same time as for control cells. LÄS MER

  5. 4. Development of intimal hyperplasia in transplant arteriosclerosis

    Författare :Piotr Religa; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Vascular disease is the main cause of disability and mortality in the western world and the major limiting factor for long- term survival of transplanted organs. Occlusive vascular lesions lead to ischemia and structural changes in organs and in transplant arteriosclerosis and restenosis after endovascular procedures, narrowing of the vessel lumen is partly due to intimal hyperplasia caused by smooth muscle cells (SMCs).
