摘要
同种异体器官移植后的排斥反应,尤其是急性排斥反应仍然是导致移植失败和患者死亡的主要原因。活化T细胞在移植排斥反应中起着关键作用。已有研究表明,共刺激分子的表达与同种异体移植排斥反应有关。CD28/CTLA-4与CD40/CD40L通路是导致T细胞活化的两个重要共刺激通路。着重阐述了CD28/CTLA-4-B7通路在此种排斥反应中的作用。
Allograft rejection after xero organ transplantation rejection, especially acute rejection is still the major reason of failure and death. Active T cell play key roles in allograft rejection. It has been showed that the expressions of costimulatory molecules are associated with xero organ transplantation rejection. The pathways of CD28/CTLA-4 and CD40/CD40L are important costimulatory pathways that cause T cell activation.The article emphasizes on the role of CD28/CTLA-4-B7 pathway in allograft rejection.
