  1. 1. Interaction Studies in Complex Fluids with Optical Biosensors

    Författare :Jenny Carlsson; Bo Liedberg; Kjell Janné; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Type 1 diabetes; Insulin; Lectin panel; Ellipsometry; Meat juice; Serum proteins; Chemistry; Kemi;

    Sammanfattning : In this thesis interactions in complex fluids, such as serum and meat juice, were analysed with optical biosensor techniques.Panels of lectins immobilised on gold surfaces were used for investigation of differences in protein glycosylation pattern in sera and meat juices between various species.

  2. 2. Synthetic Galectin Inhibitors Selective O-galactosyl aldoximes, multivalent lactosides and galactose-mimicking mannosides

    Författare :Johan Tejler; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Proteiner; enzymology; Proteins; Glycomimetic; Fragment based; Cluster effect; Multivalence; Triazole; Inhibitor; Aldoxime; enzymologi; Organic chemistry; Organisk kemi; Galectin; Lectin;

    Sammanfattning : This thesis describes the design, synthesis and evaluation of synthetic inhibitors for the carbohydrate binding proteins called galectins. Potent and selective inhibitors can be used as important research tools in the endeavor to chart the true role of galectins in biological events such as cancer and inflammation and possibly as lead for future galectin targeting drugs.

  3. 3. Genetic and immunological studies of experimental arthritis, with emphasis on a novel C-type lectin receptor gene complex

    Författare :Jian Ping Guo; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Rheumatoid Arthritis (RA) is a chronic, systemic autoimmune syndrome primarily affecting peripheral joints. The etiology of RA is largely unknown but complex interactions between genetic and environmental factors contribute to the disease. Arthritis models more or less resembling RA are used to search for clues. LÄS MER

  4. 4. Role of GPIbαlpha Clustering and N-linked Carbohydrates in the Clearance of Refrigerated Platelets

    Författare :Emma Josefsson; Göteborgs universitet; []
    Nyckelord :Platelets; GPIbalpha; alphaMbeta2; phagocytosis; refrigerated platelets;

    Sammanfattning : The thesis focuses on understanding the mechanisms by which: 1) the macrophage alphaM-subunit recognizes betaN-acetylglucosamine (betaGlcNAc) residues on the von Willebrand factor receptor complex ((GPIbalpha,beta/IX)2V or vWfR) on refrigerated platelets and 2) refrigeration changes vWfR to elicit recognition through alphaMbeta2. Until recently, the only well-established mechanisms affecting platelet survival were antibody-mediated platelet clearance, consumption of platelets by coagulation reactions, and loss due to massive bleeding.

  5. 5. Glycosylation in cancer and infection : the role of sialic acid

    Författare :Yuecheng Zhang; Anette Wingren; Maria Stollenwerk; Lars Ohlsson; Martin Dufva; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cancer; sialic acids; receptor; molecularly imprinted polymers; SARS-CoV-2; fluorescence; Health and society; Hälsa och samhälle;

    Sammanfattning : Sialic acids (SA), a group of nine-carbon backbone monosaccharides are abundantly expressed in vertebrates. They are usually linked to the terminal of glycan chains and play crucial roles in many biological processes, including cell adhesion, cell-cell interactions, immune modulation, cancer cell migration and invasion, as well as viral infections.
