With the use of immunohistochemical techniques, seven mouse monoclonal antibodies and the lectin from Ulex europaeus, detecting blood group antigens of the ABH and Lewis systems, have been used to define the distribution of these antigenic structures in germ cell tumors. The reagents used recognize the following blood group antigens: A, B, H, Lewisa, Lewisb, X (Lewisx), Y (Lewisy), and type I p...

Histo-blood group antigens (HBGAs) are commonly accepted as the cellular receptors for human norovirus. However, some human noroviruses have been found not to bind any HBGA ligand, suggesting potential additional co-factors. Some ligands have been found to bind noroviruses and have the potential to be additional cellular receptors/attachment factors for human norovirus or inhibitors of the HBGA...

Norovirus (NoV) is the major causative agent of acute viral gastroenteritis worldwide. Based on genetic analyses, human NoV strains have been classified into at least three genogroups: genogroup I (GI), GII, and GIV, which contain at least 15, 18, and 1 genotypes, respectively (Kageyama et al., 2004). Notably, these NoV genotypes are morphologically similar to one another but differ antigenical...

Human red cells incubated with a solution containing 6% 2-aminoethylisothiouronium bromide (AET) lose activity of antigens that are part of, or related to, the Kell blood group system. However, Kx antigen is not inactivated. Studies on a wide range of other blood-group antigens show no other evidence of changes and AET appears to react specifically with red-cell membrane structures that have Ke...

BACKGROUND Sickle cell anemia (SCA) is an inherited hemoglobin disorder characterized by chronic anemia and occasional crises. Clinical features are variable. While some individuals are relatively stable and rarely require blood transfusion, others often require blood transfusion. Multiple blood transfusion is associated with complications including alloimmunization, infections, and iron overlo...

Antigens of the ABO blood group system (i.e., A, B, and H antigens) and Rhesus factor were discovered more than one century ago by karl & steiner [1,2] who is considering the father of transfusion medicine, and with this discovery he enabling physicians to transfuse blood without endangering the patient′s life. The ABO antigens are defined by carbohydrate moieties on the extracellular surface o...

AIM To study the MUC5AC and the blood group related antigen expression in ocular cicatricial pemphigoid (OCP) according to the distribution of Lewis and secretor phenotypes in OCP patients compared to normal subjects. METHODS Immunostaining was performed on conjunctival biopsy specimens from 22 consecutive patients suffering from OCP, using monoclonal antibodies (Mabs) directed against the pe...

Human and chicken erythrocytes are readily coated in vitro by blood group active protein-lipopolysaccharides and lipopolysaccharides from E. coli O(86) and E. coli O(128). Serum albumin, alpha(2)- and beta-lipoproteins inhibit this sensitization. Blood group B specific agglutination of erythrocytes with B or B-like antigens was obtained with antibodies purified by adsorption on and elution from...

R DECADES, knowledge about blood group antigens I? has constituted the basis for sound transfusion practice. Although blood group serology may seem a research area largely restricted to the surface antigens on human red blood cells (and platelets), many of the known blood group antigens have a far broader tissue expression than generally acknowledged. The AB0 blood group system, discovered in 1...
