11. Biophysical studies of membrane associated peptides
Sammanfattning : A large part of the processes in living organisms involves proteins acting in a biological membrane. Biophysical studies on isolated model systems can give important understandings of the complicated biological mechanisms in the membrane. In this thesis peptide membrane interaction mechanisms are studied in several different systems. LÄS MER
12. Interactions of Prion Proteins and PrP-derived Peptides in Scrapie infection
Sammanfattning : Prion diseases are fatal and incurable spongiform encephalopathies that occur amongst mammals. The central pathological event is the misfolding of the cellular prion protein (PrPC) into an amyloid, neurotoxic isoform called scrapie (PrPSc). PrPSc is the main, or sole, constituent of infectious prions. LÄS MER
13. Biophysical studies of peptides with functions in biotechnology and biology
Sammanfattning : My thesis concerns spectroscopic studies (NMR, CD and fluorescence) of peptides with functions in biotechnology and biology, and their interactions with a model membrane (large unilamellar phospholipid vesicles).The resorufin-based arsenical hairpin binder (ReAsH) bound to a short peptide is a useful fluorescent tag for genetic labeling of proteins in living cells.

14. Cell-penetrating peptides in model membrane systems : Interaction, structure induction and membrane effects
Sammanfattning : Despite continuing advances in the development of macromolecules, including peptides, proteins, and oligonucleotides, for therapeutic purposes, the successful application of these hydrophilic molecules has so far been hampered by their inability to efficiently traverse the plasma membrane. The discovery of a class of peptides (cell-penetrating peptides, CPPs) with the ability to mediate the non-invasive and efficient import of a whole host of cargoes, both in vitro and in vivo, has provided a new means by which the problem associated with cellular delivery can be circumvented.
