Objective To investigate the relationship between the level of Foxp3 mRNA in the peripheral blood monocytes (PBMCs) with acute rejection or chronic allograft nephropathy after kidney allotransplantation. Methods Real-time quantitative polymerase chain reaction was used to examine Foxp3 mRNA expression in the PBMCs from 16 patients with acute rejection, 8 patients with chronic allograft nephropathy, 8 patients at stable stage after kidney transplantation, 8 patients of end-stage renal disease, and 8 normal controls. Results The level of Foxp3 ...
