PLA2R1 and membranous glomerulonephritis: In conclusion, these multicenter studies, including the first prospective study on membranous nephropathy recurrence after kidney transplantation, not only confirmed the predictive value of pretransplant anti-PLA2R1 antibodies but also showed that the presence of pretransplant anti-PLA2R1 antibodies could predict the recurrence regardless of their level.
