  1. 11. Neutrophil extracellular traps : function in infectious and non-Infectious conditions

    Författare :Beatrice Lazzaretto; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Neutrophil extracellular traps (NETs) are composed of a backbone of chromatin, decorated with microbicidal peptides and proteolytic enzymes, and are used by neutrophils as a weapon against pathogens. Since their initial discovery in 2004, NETs have challenged scientists in terms of the nature of the triggers and the mechanisms of neutrophil release of NETs, as well as the implication of these extracellular structures in infectious and non-infectious human diseases.

  3. 12. Enzymes involved in biosynthesis and degradation of heparin-related polysaccharides

    Författare :Dagmar Sandbäck Pikas; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; heparin; heparan sulphate; biosynthesis; N-deacetylase N-sulphotransferase; endoglycosidase; heparanase; Biokemi; Biochemistry; Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

    Sammanfattning : Heparin and heparan sulphate (HS) are structurally related polysaccharides of the glycosaminoglycan type. As the glycan moiety of proteoglycans, they exist covalently linked to various core proteins. LÄS MER

  4. 13. Towards surgical use of matrix metalloproteinase biology

    Författare :Björn Pasternak; Per Aspenberg; Pentti Tengvall; Yrjö T Konttinen; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Achilles tendon; colon; tetracyclines; tissue inhibitor of metalloproteinases TIMP ; wound healing.; colorectal surgery; extracellular matrix; humans; matrix metalloproteinases MMPs ; rats; surgical anastomosis; sutures; tendon injuries; Orthopaedics; Ortopedi;

    Sammanfattning : Matrix metalloproteinases (MMPs), such as collagenases, are a family of enzymes capable of degrading most constituents of the extracellular matrix. MMPs are thought to be involved in the aetiopathogenesis of tendon rupture. Additionally, failure of healing has in some instances been associated with elevated levels of MMPs. LÄS MER

  5. 14. Fatty acids induce potentially atherogenic changes in extracellular matrix proteoglycans

    Författare :Mariam Rodríguez-Lee; Göteborgs universitet; []
    Nyckelord :proteoglycans; glycosaminoglycans; fatty acids; smooth muscle cells; hepatocytes; LDL binding; remnant clearance; insulin resistance; type 2 diabetes;

    Sammanfattning : Insulin resistance and type 2 diabetes (T2D) are associated with an increased prevalence of atherosclerotic cardiovascular disease (CVD). A key step in the initiation of atherogenesis is retention of low density lipoproteins (LDL) in the intima by chondroitin sulfate (CS)-rich proteoglycans (PG). LÄS MER

  7. 15. Biosynthesis, Processing, and Sorting of Human Neutrophil Granule Proteins. Focus on Cathepsin G, Proteinase 3, and Azurocidin

    Författare :Daniel Garwicz; Avdelningen för hematologi och transfusionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematologi; extracellular fluids; Haematology; differentiation; bone marrow progenitor cells; preproform; mutations; Cell lines; transfection; extracellulära vätskor;

    Sammanfattning : The neutrophil granulocyte contains a number of multifunctional proteins stored in different subsets of granules. The azurophil granules, synthesized early during differentiation, harbour leukocyte elastase, cathepsin G, proteinase 3, and azurocidin; the members of the serprocidin family. LÄS MER
