Alloreactive and proliferating CD4 T‐cells recognizing allogeneic/donor HLA‐DR molecules on endothelial cells were attenuated in the presence of anti‐A/B antibodies. Anti‐A/B antibodies ligation on endothelial cells increased PD‐L1 expression. Amplified expression of transcript encoding PD‐L1 was observed in biopsy samples from ABO‐I renal transplants.
