器官移植是治疗终末期器官功能衰竭的有效手段，但排斥反应是影响其成功率的主要障碍。尽管强力免疫抑制剂（如ＣｓＡ等）应用于临床以来，排斥反应的发生率有所下降，但早期急性排斥反应发生率仍很高，加之长期服用免疫抑制剂引起的毒副作用等，极大地影响了器官移植的成功率 Organ transplantation is an effective treatment for end-stage organ failure, but rejection is a major obstacle to its success rate. Although the incidence of rejection has declined since potent immunosuppressive agents (such as CsA, etc.) have been used clinically, the incidence of early acute rejection is still high, and the side effects caused by long-term use of immunosuppressive agents greatly affect The success rate of organ transplantation
