1. 1. Viperin vs. tick-borne encephalitis virus : mechanism of a potent antiviral protein

   Författare :Kirstin Vonderstein; Anna Överby Wernstedt; Magnus Evander; Sonja Best; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tick-borne encephalitis virus; TBEV; type-I interferon; IFN; Interferon-stimulated gene; ISG; viperin; GBF1; CIAO1; antiviral protein; genome replication; particle release; capsid;

   Sammanfattning : Tick-borne encephalitis virus (TBEV) is a very important virus medically, causing mild or severe encephalitis often with long-lasting sequelae. Treatment of tick-borne encephalitis is limited to supportive care, and antiviral drugs are much needed.The type-I interferon (IFN) system is the first line of host defense against many viruses.

3. 2. On the Biosynthesis and Processing of Cathepsin G, Leukocyte Elastase, and Azurocidin ­ neutrophil granule members of a hematopoietic serine protease superfamily

   Författare :Anders Lindmark; Avdelningen för hematologi och transfusionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellular fluids; Haematology; sorting; Activation; propeptide; Hematologi; extracellulära vätskor;

   Sammanfattning : The serine proteases cathepsin G, leukocyte elastase, proteinase 3, and the inactive protease homologue azurocidin, stored in the azurophil granules of neutrophils, belong to a hematopoietic serine protease superfamily with members in mature effector cells of bone marrow origin. Promonocytic U-937 cells were used for studying the biosynthesis of cathepsin G and leukocyte elastase by biosynthetic radiolabelling. LÄS MER

4. 3. Involvement of Heparan Sulphate Biosynthesis and Turnover in Cell Proliferation. A Novel Role for Nitric Oxide in Recycling of Heparan Sulphate Proteoglycans

   Författare :Katrin Mani; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nitrite.; nitric oxide; growth-inhibition; xyloside; glypican; heparan sulphate; Proteoglycan; glycosaminoglycan; Clinical biology; Klinisk biologi;

   Sammanfattning : The present investigation focuses on the role of HS metabolism in cell proliferation. The effect of the HS priming ß-D-xyloside, 2-(6-hydroxynaphthyl)-O-ß-D-xylopyranoside (Xyl-2-Nap-6-OH) on the proliferation of normal and transformed cells was studied. LÄS MER

5. 4. Studies on the assembly and secretion of apolipoprotein B containing lipoproteins

   Författare :Karin Lindberg; Göteborgs universitet; []
   Nyckelord :apolipoprotein B; lipoprotein; lipoprotein biosynthesis; Brefeldin A; microsomal triglyceride transfer protein; liver fatty acid binding protein;

   Sammanfattning : Lipoproteins are water-soluble particles of lipids and proteins, which deliver water-insoluble lipids from intestine or liver to target tissues where the lipids are used as fuel or storage. Lipoproteins consist of a core of hydrophobic lipids surrounded by an amphipatic monolayer of polar lipids and specific proteins, apolipoproteins. LÄS MER

7. 5. Folding and retention of rotavirus glycoproteins in the endoplasmic reticulum

   Författare :Ali Mirazimi; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :ER; rotavirus; VP7; NSP4; oligosaccharide processing; N-linked glycosylation; protein disulfide isomerase; calnexin; ATP; ER retention;

   Sammanfattning : The endoplasmic reticulum (ER) is a membrane bound organelle composed of a network of cisternae stretching throughout the cytoplasm. Functionally, the ER performs many essential processes, such as glycosylation, and biosynthesis of lipids; it provides a redox potential condition for forming S-S linkages, and a quality control system, and functions as an intracellular calcium store.
