  1. 11. Characterization of artificial and biological lipid vesicles using TIRF and SPR

    Författare :Thomas Olsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; membrane permeability; chromaffin vesicle; fluorescence; total internal reflection TIRF microscopy; surface plasmon resonance SPR ; vesicle; osmotic shock; cell membrane; liposome; nanoparticle tracking analysis NTA ; large dense core vesicles LDCVs ;

    Sammanfattning : Synthetic lipid vesicles serve as important mimics of cells and the natural membranes that they are enclosed by. As such they are frequently used as simplified models of the highly complex cell membrane to aid in-depth physicochemical and biological characterization of this essential biological structure.

  3. 12. Bacterial Outer Membrane Vesicles. Mediators of virulence and antibiotic resistance

    Författare :Viveka Schaar; Malmö Klinisk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antibiotic resistance; Moraxella catarrhalis; epithelial cells; beta-lactamase; non-typeable Haemophilus influenzae; outer membrane vesicles; polymicrobial infections; UspA1;

    Sammanfattning : Outer membrane vesicles (OMV) have the size of nanoparticles and are released from the outer membrane of most Gram-negative bacteria. The OMV reflect the composition of the bacterial outer membrane, including lipids and virulence factors specific for the pathogen, and are involved in pathogenesis and bacterial survival. LÄS MER

  7. 15. Property-controlling Enzymes at the Membrane Interface

    Författare :Changrong Ge; Åke Wieslander; Marcelo E. Guerin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; monotopic membrane protein; lipid-protein interaction; membrane curvature; glycosyltransferase; Rossmann fold; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Monotopic proteins represent a specialized group of membrane proteins in that they are engaged in biochemical events taking place at the membrane interface. In particular, the monotopic lipid-synthesizing enzymes are able to synthesize amphiphilic lipid products by catalyzing two biochemically distinct molecules (substrates) at the membrane interface.
