  2. 1. Norovirus, causative agent of winter vomiting disease, exploits several histo-blood group glycans for adhesion

    Author : Gustaf E Rydell; Göteborgs universitet; []
    Keywords : norovirus; glycobiology; virus-like particle; FUT2; ABO H histo-blood group antigen; sialyl Lewis x; neoglycoprotein; glycosphingolipid; QCM-D; supported lipid bilayer;

    Abstract : Norovirus is recognized as the major cause of outbreaks of gastroenteritis world-wide, yet no vaccines or drugs are available for prevention or treatment of the virus infection. Challenge studies and binding studies using virus-like particles (VLPs) have suggested susceptibility to norovirus infection to be associated with secretor status. READ MORE

  4. 2. Genetics and Expression of Glycosphingolipids in the P1PK and GLOB Histo-Blood Group Systems

    Author : Julia Westman; Avdelningen för hematologi och transfusionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glycosphingolipid; glycosyltransferase; null allele; GLOB; P1PK; Blood group;

    Abstract : The glycosphingolipid (GSL) antigens in the clinically important P1PK and GLOB blood group systems are present on erythrocytes as well as other tissues and are so-called histo-blood group antigens. Blood group antigens of carbohydrate nature are products of enzymes, so-called glycosyltransferases, adding sugars in a step-wise manner to an acceptor substrate. READ MORE

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

    Author : Linn Stenfelt; Avdelningen för hematologi och transfusionsmedicin; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Studies on the Polymorphism and Transcriptional Regulation of the ABO and P1PK Histo-blood Group Genes

    Author : Britt Thuresson; Avdelningen för hematologi och transfusionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood group; ABO; A4GALT; P1PK; Gene regulation; Enhancer;

    Abstract : Antigens of the clinically important ABO and P1PK blood group systems are carbohydrate structures. Thus the underlying genes do not encode antigens directly but glycosyltransferases that add specific sugar molecules to selected precursor chains. READ MORE

  7. 5. Studies of the ABO and FORS Histo-Blood Group Systems: Focus on Flow Cytometric and Genetic Analysis

    Author : Annika Hult; Avdelningen för hematologi och transfusionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood Group; ABO; Weak expression; FORS; Flow cytometry;

    Abstract : ABO is the clinically most important blood group system and its antigens are carbohydrate moieties present on the surface of the red blood cell (RBC) but also on other tissues throughout the body. The ABO gene encodes an enzyme, a glycosyltransferase (GT),that adds a terminal monosaccharide to the precursor structure, H antigen, to define the A or B antigens. READ MORE
