Core fucosylation and IgG function in NAIT

Abstract

In this issue of Blood, Kapur et al show that maternal human platelet-specific antigen 1a (HPA 1a)-specific antibodies causing neonatal alloimmune thrombocytopenia (NAIT) possess oligosaccharides that are deficient in "core fucose" residues and appear to be more effective than fucosylated antibodies in promoting phagocytosis of antibody-coated platelets. © 2014 by The American Society of Hematology.
