Antibodies against ARHGDIB are associated with long-term kidney graft loss

The clinical significance of non‐HLA antibodies on renal allograft survival is a matter of debate, due to differences in reported results and lack of large‐scale studies incorporating analysis of multiple non‐HLA antibodies simultaneously. We developed a multiplex non‐HLA antibody assay against 14 proteins highly expressed in the kidney. In this study, the presence of pretransplant non‐HLA antibodies was corre
