3. 22. Functionalization and characterization of surface supported lipid membranes and their application in cell culture

   Författare :Dorota Thid; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cell - surface interaction; supported phospholipid bilayer; IKVAV; DHA; stem progenitor cells; neural cells; surface analytical techniques; QCM-D; surface functionalization; peptide; cell differentiation; cell attachment; membrane; fatty acid;

   Sammanfattning : Phospholipid bilayers supported on a solid surface constitute a versatile, biomimetic platform for a variety of applications, such as biosensing, drug delivery research, cell engineering and as cell membrane mimics in fundamental cell research. Phosphocholine supported lipid bilayers are resistant to cell attachment in a wide range of conditions, and can be functionalized with bioactive signaling molecules to promote specific interactions with cells.

4. 23. Identification of new virulence factors in Francisella tularensis

   Författare :Anna-Lena Forslund; Åke Forsberg; Elisabeth Carniel; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Francisella tularensis; regulation; virulence; Hfq; DsbA; type IV pili; membrane; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

   Sammanfattning : Francisella tularensis, the causative agent of tularemia, is a highly virulent bacterium with an infection dose of less than ten bacteria. The ability of a pathogen to cause infection relies on different virulence mechanisms, but in Francisella tularensis relatively few virulence factors are known. Two F. LÄS MER

5. 24. Electrophysiology of pancreatic A-, B- and D-cells studied in intact mouse islets of Langerhans

   Författare :Sven Göpel; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; somatostatin; glucagon; insulin; patch-clamp; membrane potential; Pancreatic islet; ion channel; diabetes; Physiology; Fysiologi;

   Sammanfattning : Abstract The electrophysiological properties of insulin-secreting b-cells, glucagon-releasing a-cells and somatostation-producing d-cells in intact mouse pancreatic islets were investigated using the perforated patch whole-cell technique. It is demonstrated that it is possible to functionally identify the different cell types in situ. LÄS MER

7. 25. Therapeutic potential of extracellular vesicles

   Författare :Oscar Wiklander; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Extracellular vesicles (EVs) are nanometer-sized, lipid membrane enclosed, vesicles that are secreted by most, if not all, cells and contain macromolecular material of the source cell including lipids, proteins and various nucleic acid species. Over the last two decades, EVs have been recognized as important mediators of cell-to-cell communication that influence both physiological and pathological conditions. LÄS MER
