摘　　要：目的 探讨肾移植急性排斥反应时白细胞介素6(IL-6)产生的主要来源,并为初步阐明肾移植急性排斥反应的分子学发病机制提供实验依据。方法 采用3＇IL-6寡核苷酸探针,运用原位杂交技术观察IL-6mRNA在移植肾中的表达。结果 (1)在急性排斥反应时,移植肾各部位表达IL-6mRNA明显增多,较环孢素A(CsA)中毒、稳定期移植肾及正常人均有显著升高。(2)在急性排斥反应时,肾小管上皮细胞表达IL-6mRNA强度较肾小球细胞、血管内皮细胞及间质细胞均有明显升高。(3)CsA中毒患者肾脏IL-6mRNA表达较稳定期移植肾及正常对照无明显增多。结论 肾移植急性排斥反应时,移植肾细胞可直接产生IL-6,移植肾中IL-6异常激活与表达同肾移植急性排斥反应的发生机制有密切的关系;肾小管表达IL-6的异常增多和活化揭示了肾小管上皮细胞在肾移植急性排斥反应的发病机理中具有重要意义。Objective To investigate the main origin of IL-6 during acute rejection of renal transplantation and provide the experimental foundations for expounding the molecular pathogenic mechanism of acute rejective reaction of renal transplantation Methods 3'IL-6 probe with in situ hybridization technique was used to detect the IL-6mRNA expression in renal graft. Results (1) Renal graft expression of IL-6mKNA in acute rejection was higher than that in CsA toxicosis, stable transplantation and normal control. (2) Expression of IL-6mRNA in tubular epithe-lium of acute rejection graft was higher than that in glomerular cells ,vascular endotheli-um and interstitium. (3) The expression of IL-6mRNA in renal graft of CsA toxicosis was similar with that in stable transplantation and normal control. Conclusion Renal graft cells may produce IL-6 directly during acute rejection. The abnormal expression and activation of IL-6 in renal graft may play an important role in the mechanism of renal acute rejection. Graft tubular epithelium may play a more important role in the cause of immunorejection.
