2. 6. Cell Contacts and Airway Epithelial Damage in Asthma

   Author : Shahida Shahana; Godfried Roomans; Rolf Odselius; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anatomy; Desmosomes; tight junctions; major basic protein; eosinophil; cytokines; epithelial damage.; Anatomi; Anatomy; Anatomi;

   Abstract : Airway epithelial damage is commonly found in asthma patients. Epithelial damage was investigated with special reference to contacts between epithelial cells.Eosinophils, common in allergic asthma, secrete cationic proteins, particularly major basic protein (MBP). READ MORE

4. 7. Functionalization and characterization of surface supported lipid membranes and their application in cell culture

   Author : Dorota Thid; Chalmers tekniska högskola; []
   Keywords : 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;

   Abstract : 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.

5. 8. Plasma membrane order; the role of cholesterol and links to actin filaments

   Author : Jelena Dinic; Ingela Parmryd; Gerrit van Meer; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Membrane Organization; Lipid rafts; Actin; Laurdan; di-4-ANEPPDHQ; Cholesterol; T cell signaling; Colocalization; Generalized Polarization; Cell Biology; cellbiologi;

   Abstract : The connection between T cell activation, plasma membrane order and actin filament dynamics was the main focus of this study. Laurdan and di-4-ANEPPDHQ, membrane order sensing probes, were shown to report only on lipid packing rather than being influenced by the presence of membrane-inserted peptides justifying their use in membrane order studies.

6. 9. Study of the Proliferation, Function and Death of Insulin-Producing Beta-Cells in vitro: Role of the Transcription Factor ZBED6

   Author : Xuan Wang; Nils Welsh; Nils Billestrup; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ZBED6; Pancreatic beta-cell; Proliferation; Insulin secretion; Apoptosis; Adhesion; Medical Science; Medicinsk vetenskap;

   Abstract : A thorough understanding of beta-cell proliferation, function, death and regeneration under normal condition as well as in the progression of diabetes is crucial to the conquest of this disease. The work presented in this thesis aimed to investigate the expression and role of a novel transcription factor, Zinc finger BED domain-containing protein 6 (ZBED6), in beta-cells. READ MORE

7. 10. Ultrastructural Studies of the Airway Epithelium in Airway Diseases

   Author : Eyman Shebani; Godfried M. Roomans; Marie Johannesson; Anil Mehta; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Morphology; asthma; cilia; corticosteroids; cytokines; desmosomes; Gaucher’s disease; montelukast; primary ciliary dyskinesia; transmission electron microscopy; Morfologi; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi;

   Abstract : Ultrastructural studies of airway epithelium in airway disease are important for diagnosis and understanding the underlying pathology which helps clinicians to improve the patients' treatment.Airway biopsies from a 5-month old boy with respiratory problems and gastro-oesophageal reflux were studied by transmission electron microscopy (TEM).
