6. Affinity-, Partition- and Permeability Properties of the Human Red Blood Cell Membrane and Biomembrane Models, with Emphasis on the GLUT1 Glucose Transporter
Sammanfattning : The human glucose transporter GLUT1 is abundant in red blood cells, the blood-brain barrier and epithelial cells, where it mediates the transport of the energy metabolite, glucose. In the present work some properties of GLUT1, including affinity binding of both substrates and inhibitors, transport rates as well as permeabilities of aromatic amino acids and drug-membrane interactions were analyzed by chromatographic methods.

7. Chromatographic Studies of Solute Interactions with Immobilized Red Blood Cells and Biomembranes
Sammanfattning : Specific and non-specific interactions of solutes with immobilized biomembranes were studied using chromatographic methods. Liposomes, proteoliposomes and red blood cell (RBC) membrane vesicles were immobilized by a freeze-thawing procedure, whereas whole RBCs were adsorbed in the gel beds using electrostatic interaction, binding to wheat germ agglutinin (WGA) or the streptavidin-biotin interaction.

8. Property-controlling Enzymes at the Membrane Interface
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.

9. Pathogen entry mechanisms and endocytic responses to plasma membrane damage
Sammanfattning : Endocytosis is a fundamental cellular process by which cells transport material from the outside to the inside of the cell through the formation of membrane invaginations that bud off from the plasma membrane. This process is important for nutrient uptake, regulating cell surface receptors and the overall plasma membrane composition. LÄS MER
10. 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
