11. Development of Surface-Based Methods for Studies of Non-Electrolyte Membrane Transport
Sammanfattning : Membrane-transport proteins are a diverse family of proteins that all span the cell membrane where they control the transfer of nutrients, metabolites and ions into and out of the cell. Due to their vital role for the function of cells, reliable methods, preferably with high-throughput capacity, to study this class of proteins are essential in fundamental studies as well as in discovery and development of new drugs.

12. Plasma membrane arabinogalactan proteins
Sammanfattning : Arabinogalactan proteins (AGPs) are proteoglycans found at the outer side of the plasma membrane and in the extracellular matrix of plants. To be able to study the plasma membrane bound AGPs, a method using SDS-agarose gel electrophoresis (SDS-AGE) was developed to overcome the problems associated with electrophoretic separation of highly glycosylated proteins.

13. Probing and elucidating the dynamics of virus-membrane interaction via plasma membrane mimics
Sammanfattning : Virus infection is initiated by the attachment of a virion to a susceptible cell’s plasma membrane, in a highly dynamic and well-orchestrated process that encompasses various steps and engages numerous viral and cellular factors. These dynamic steps may include initial non-specific binding to ubiquitous cell-membrane ligands, diffusion across the membrane to a suitable entry site and virus engagement with various receptors and co-receptors on the cell surface.

14. Membrane transport of triiodothyronine : With particular reference to erythrocytes in health and disease
Sammanfattning : Cellular T3 uptake was studied in three human cell systems, i.e. cultured lymphocytes, erythrocytes and erythrocyte membrane vesicles. LÄS MER
15. Membrane transport and the human small intestine : Relation to mucosal protection, intestinal anaphylaxis and nitric oxide
Sammanfattning : The tightly adherent monolayer of epithelial cells that line the luminal side of the intestine provides a dynamic and highly regulated barrier to the passive and active transport of ions, water and macromolecules. Cathecol-O-methyl transferase inhibition prevents tissue degradation of catecholaminesincluding dopamine and intracellular carbonic anhydrase activity is an important regulator of ion and water transport in the small intestine.
