  2. 1. Sarcoidosis : expression of cell regulatory markers and the influence of patient phenotype on bronchoalveolar lavage cell differential counts

    Author : Muntasir Abo Al Hayja; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Sarcoidosis is a systemic inflammatory disease that can affect almost any organ, but the respiratory system is affected in more than 90% of the cases. To elicit an immune response, an antigen(s) is processed by antigen-presenting cells (APCs), e.g. READ MORE

  4. 2. Chemical basis of ABO subgroups

    Author : Lola Svensson; Göteborgs universitet; []
    Keywords : ABO; subgroups; glycolipid; para-Forssman; Forssman; Forssman synthetase;

    Abstract : Despite the ABO histo-blood group system being the most biologically significant in humans the chemical structures that define its various phenotypes still remain largely unresolved. Like all blood group systems there is a significant range in the amount of antigen present on the red cells of an individual and there exists a range of so-called “weak” phenotypes represented by decreasing expression of A or B antigens.

  5. 3. 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

  6. 4. 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

  7. 5. Genetic Characterisation of Human ABO Blood Group Variants with a Focus on Subgroups and Hybrid Alleles

    Author : Bahram Hosseini Maaf; Avdelningen för hematologi och transfusionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glycosyltransferase; SNP; computer modelling; ABO genotyping; Immunology; serology; hybrid; Blood group ABO; transplantation; subgroup; Immunologi; serologi; rare O allele;

    Abstract : ABO is the most important blood group system in transfusion medicine and transplantation immunology. The ABO blood groups differ by the presence or absence of antigens on RBCs and antibodies in plasma. Accurate determination of ABO status is critical. Genomic typing can increase the precision of blood group determination in complicated cases, e. READ MORE
