Biological roles of blood group antigens.
Recognition and application of blood group differences on human red cells permitted the development of safe procedures for blood transfusion. Blood group antigens are markers on surface-exposed red cell proteins or the sugar moiety of glycoproteins or glycolipids. Apart from their presumed biological function, some antigens have been identified as receptors for host/parasite interactions. Thus,...
متن کاملPassive modulation of blood-group antigens.
Rh-positive erythrocytes were enriched and depleted of membrane cholesterol, and the mediated change in the degree of exposure of the D antigens was determined by fluorescence-activated cell sorting, using indirect fluorescent antibody labeling. The results are compatible with a model in which the expression of the D antigens can be modulated significantly by the lipid microviscosity (eta). At ...
متن کاملRelationship of blood groups to pemphigus: Do blood group antigens have a biological role? A Case-control study
Background: ABO blood group antigens may play a role in the pathophysiology of certain diseases. Several studies have investigated the relation between blood group and autoimmune disorders. In this research, we evaluated the associations between ABO blood types and rhesus (Rh) factor in pemphigus patients.Methods: In this case-control, hospital-based study, we evaluated the prevalence of blood ...
متن کاملABO blood-group antigens in oral cancer.
Tumor progression is often associated with altered glycosylation of the cell-surface proteins and lipids. The peripheral part of these cell-surface glycoconjugates often carries carbohydrate structures related to the ABO and Lewis blood-group antigens. The expression of histo-blood-group antigens in normal human tissues is dependent on the type of differentiation of the epithelium. In most huma...
متن کاملRh and LW blood group antigens
History and nomenclature The Rh system is second only to the ABO system in importance in transfusion medicine because Rh antigens, especially D, are highly immunogenic and cause hemolytic disease of the fetus and newborn (HDFN) and hemolytic transfusion reactions (HTRs). HDFN was first described by a French midwife in 1609 in a set of twins, one of whom was hydropic and stillborn, whereas the o...
