  1. 11. Dynorphin A – Interactions with receptors and the membrane bilayer

    Författare :Johannes Björnerås; Lena Mäler; Astrid Gräslund; Göran Widmalm; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biophysics; biofysik; Biochemistry; biokemi;

    Sammanfattning : The work presented in this thesis concerns the dynorphin neuropeptides, and dynorphin A (DynA) in particular. DynA belongs to the wider class of typical opioid peptides that, together with the opioid receptors, a four-membered family of GPCR membrane proteins, form the opioid system. LÄS MER

  2. 12. Properties and Applications of Shear-Driven Lipid Bilayers

    Författare :Peter Jönsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photobleaching; cell membrane; simulations; fluorescence microscopy; microfluidics; diffusivity; membrane proteins; lipid bilayer; mobility; model systems;

    Sammanfattning : A supported lipid bilayer (SLB) is a lipid bilayer formed on a solid substrate. This system is currently one of the most common model systems used to imitate the properties of the cell membrane that surrounds human cells. LÄS MER

  3. 13. Mesoporous supported lipid bilayers

    Författare :Maria Claesson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; FRAP; Lipid bilayer; Mesoporous; AFM; Vesicle; Titania; Silica; QCM-D;

    Sammanfattning : AbstractLipid bilayers are commonly used as simplified model systems of living cell membranes. They have shown to be important components in the development of biosensing devices where the bilayer acts as a host for transmembrane proteins, such as ion channels, that are utilized as sensing elements.

  4. 14. Computational modeling of biological barriers

    Författare :Christian Wennberg; Erik Lindahl; Thomas Cheatham; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular dynamics; cholesterol; lipid bilayer; permeability; long-range interactions; Lennard-Jones; dispersion; particle-mesh Ewald; stratum corneum; skin formation; Biological Physics; Biologisk fysik;

    Sammanfattning : One of the most important aspects for all life on this planet is the act to keep their biological processes in a state where they do not reach equilibrium. One part in the upholding of this imbalanced state is the barrier between the cells and their surroundings, created by the cell membrane. LÄS MER

  5. 15. Bilayer Discs - Fundamental Investigations and Applications of Nanosized Membrane Models

    Författare :Emma Johansson; Katarina Edwards; Mats Almgren; Sven Engström; Uppsala universitet; []
    Nyckelord :Chemistry; disc; threadlike micelle; liposome; model membrane; drug partitioning; cryo-TEM; Kemi;

    Sammanfattning : The bilayer disc is a flat, lipid aggregate structure in the nanometre regime. It is composed of a bilayer of amphiphilic molecules with micelle-forming amphiphilic molecules supporting the rim, which prevent disc fusion and self-closure. LÄS MER
