Crystal structures reveal HPA-1a alloantigenicity in FNAIT, highlighting implications for integrin function.

This research aims to define the molecular basis of HPA-1a alloimmunization and its implications for the pathogenesis of FNAIT.
Determined crystal structures of HPA-1a bound to four monoclonal antibodies.
Explored antibody binding interfaces on integrins αIIbβ3 and αVβ3.
Conducted functional assays on platelet aggregation and endothelial adhesion.
Identified key epitopes for antibody binding on HPA-1a.
Demonstrated differential affinities of antibodies affecting integrin activation.
Showed that antibodies inhibit platelet aggregation and endothelial adhesion.

Zhang et al. (2026) studied this question.
