Kidney transplantation to treat end-stage renal disease has evolved rapidly from the first successful transplantations to the current widespread use of grafts from both cadaveric and living donors. But acute rejection is still a strong risk factor for chronic rejection in recipients of renal grafts. To investigate possible mechanisms, we describe a comparison between differentially proteins expression and immune markers profile (IL-2, IL-4, IL-6, and CRP) of acute rejection and the controls. Through quantitative real-time RT-PCR confirmation, PDIA3 mRNA and protein expression levels in serum and transplanted kidney in experiment group was significantly (P < 0.05) higher than that in control group. Immunity analysis showed that plasma IL-2, IL-4, IL-6, and CRP levels were higher in experimental rats than those in control rats. Our data thus indicate that PDIA3 might be potentially involve into the occurence and development of acute rejection response in renal transplantation and increased plasma IL-2, IL-4, IL-6, and CRP levels play an important role to prevent acute kidney allograft rejection in rats.
肾移植治疗终末期肾病已从最初的首次成功移植迅速发展到目前广泛使用尸体和活体供体的移植物。但急性排斥反应仍然是肾移植受者发生慢性排斥反应的一个强烈危险因素。为了探讨可能的机制,我们比较了急性排斥反应和对照组之间差异表达蛋白的表达和免疫标志物谱(IL-2、IL-4、IL-6 和 CRP)。通过定量实时 RT-PCR 验证,实验组血清和移植肾中 PDIA3mRNA 和蛋白表达水平明显高于对照组(P<0.05)。免疫分析表明,实验大鼠的血浆 IL-2、IL-4、IL-6 和 CRP 水平高于对照组大鼠。因此,我们的数据表明,PDIA3 可能参与肾移植中急性排斥反应的发生和发展,增加的血浆 IL-2、IL-4、IL-6 和 CRP 水平在预防大鼠急性肾移植排斥反应中发挥重要作用。
