  1. 1. Biochemical studies of carbohydrate blood group antigens - Carbohydrate phenotype in relation to cellular glycosyltranferases

    Författare :Mette Diswall; Göteborgs universitet; []
    Nyckelord :glycosphingolipid; glycosyltransferase; genetic modification; carbohydrate; mass spectrometry; proton NMR spectroscopy; xenotransplantation; GalT-KO pig;

    Sammanfattning : The possibility to alter the cell surface carbohydrate expression by insertion or deletion of glycosyltransferase genes is a powerful technique to study the biological function of selected carbohydrate antigens. However, shifting the equilibrium between competing glycosyltransferases might lead to unexpected phenotypic effects, such as accumulation of other carbohydrate antigens and exposure of antigen structures that normally are cryptic or present in minute amounts on the cell surface.

  3. 2. Development of Flourescence-based Immunosensors for Continous Carbohydrate Monotoring : Applications for Maltose and Glucose

    Författare :Henrik Engström; Sten Ohlson; Per Ola Andersson; Christopher Lowe; Högskolan i Kalmar; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Carbohydrate; Diabetes; Immunosensor; ; Glucose; Maltose; Weak affinity chromatograhpy; Kolhydrater; Glukos; Maltose; Affinitetskromatografi; Diabetes; Biochemistry; Biokemi; Bioteknik; Biotechnology;

    Sammanfattning : Weak affinity interaction of monoclonal antibodies and carbohydrate antigens can be detected and quantified by alterations in the antibodies' intrinsic tryptophan fluorescence. These weak/transient binding events have been monitored by total internal reflection fluorescence (TlRF) by facilitating the change in intrinsic tryptophan fluorescence. LÄS MER

  4. 3. Elucidating Genetic and Biochemical Aspects of the P1 and Sda Carbohydrate Histo-Blood Group Antigens

    Författare :Linn Stenfelt; Avdelningen för hematologi och transfusionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood Group; P1 antigen; Sda antigen; A4GALT; B3GALNT2; glycosyltransferase; red blood cell; transfusion medicine;

    Sammanfattning : Human histo-blood groups are inherited polymorphic variants that occur in the molecular structures on the humanred blood cell (RBC) surface. Introducing foreign RBCs into a recipient lacking an antigen may activate the humoraldefence leading to a hemolytic transfusion reaction. LÄS MER

  5. 4. Molecular genetics of human carbohydrate defined blood groups. Studies of the ABO and P blood group systems

    Författare :Rudi Steffensen; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ABO blood group system; P blood group system; carbohydrate antigen; DNA; sequencing; populations studies; expression studies;

    Sammanfattning : The aim of this study was to explore the molecular genetics of the carbohydrate defined blood group ABO and P systems.The blood group ABO system is the clinically most significant system in transfusion medicine. Using modern molecular biology, a number of the ABO alleles have been characterized. LÄS MER

  7. 5. Studies of Carbohydrate-Binding Proteins from Enterotoxigenic Escherichia coli

    Författare :Lena Jansson; Göteborgs universitet; []
    Nyckelord :Carbohydrate recognition; ETEC colonization factors; CFA I fimbriae; CS6 protein; heat-labile enterotoxin;

    Sammanfattning : Knowledge about the carbohydrate binding specificity of pathogens can give an increased understanding of their virulence strategies, and is also of importance for the development of anti-adhesive therapies and vaccines. Enterotoxigenic Escherichia coli (ETEC) is a well-known causative agent of diarrheal disease. LÄS MER
