1. 6. Cell Behavior and the Role of Profilin

   Författare :Yu Li; Roger Karlsson; Christophe Ampe; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell biology; Cellbiologi; cellbiologi; Cellbiology;

   Sammanfattning : Profilin is a key regulator of the microfilament system. It binds to actin monomers in a 1:1 complex, forming the profilin:actin complex, which is the major precursor of actin for filament formation in vivo. The distribution of profilin has been studied in a variety of cells. It is present not only in the cytoplasm but also in the nucleus. LÄS MER

3. 7. Cholesterol in T cells : homeostasis, plasma membrane organization and signaling

   Författare :Saleemulla Mahammad; Ingela Parmryd; Thomas Harder; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plasma membrane; T cells; Cholesterol; Lipid rafts; Membrane organization; Cholesterol homeostasis; cholesteryl esters; Cell biology; Cellbiologi; Cell Biology; cellbiologi;

   Sammanfattning : The plasma membrane of eukaryotic cells contains cholesterol and glycosphingolipids enriched nanodomains known as lipid rafts; which are believed to exist in a liquid ordered (lo) state. Methyl-beta-cyclodextrin (MBCD) is used to deplete cellular cholesterol and a widespread assumption is that MBCD preferentially targets cholesterol in lipid rafts. LÄS MER

4. 8. The neuropeptide VIP and the IL-6 family of cytokines in bone : effects on bone resorption, cytokine expression and receptor signalling in osteoblasts and bone marrow stromal cells

   Författare :Emma Persson; Ulf Lerner; Andreas Kindmark; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; osteoblast; bone resorption; cytokines; IL-6; neuropeptides; VIP; transcription factor; Cell biology; Cellbiologi;

   Sammanfattning : Bone tissue is continuously degraded and rebuilt to respond to the needs of the body. Cells of the osteoblast lineage are responsible for the formation of bone, whereas the resorption of bone tissue is carried out by osteoclasts. LÄS MER

5. 9. Microencapsulation of Pancreatic Islets : A Non-Vascularised Transplantation Model

   Författare :Sara Bohman; Arne Andersson; Aileen King; Stellan Sandler; Eduard Montanya; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microencapsulation; Islet transplantation; revascularisation; alpha-cell; exendin-4; islet amyloid; Cell biology; Cellbiologi;

   Sammanfattning : Transplantation of pancreatic islets is a potential treatment of type 1 diabetes that aims to restore normal blood glucose control. By encapsulating the islets in alginate, they can be protected from rejection. LÄS MER

7. 10. Studies on Airway Surface Liquid in Connection with Cystic Fibrosis

   Författare :Inna Kozlova; Godfried Roomans; Anca Dragomir; Marieann Högman; Isabelle Sermet-Gaudelus; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cystic fibrosis; CFTR; airway surface liquid; ion content; anesthesia; mist tent therapy; Pseudomonas aeruginosa infection; Cell biology; Cellbiologi;

   Sammanfattning : Cystic fibrosis (CF) is one of the most common fatal inherited diseases, most prevalent among Caucasians. CF is caused by a mutation in the gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR), which helps to create sweat, digestive juices, and airway surface liquid (ASL).
