Antibody mediated transplant rejection (AMR) is a major cause of long-term allograft failure, and currently available treatments are of limited efficacy for treating the disease. AMR is caused by donor specific antibodies (DSA) that bind to antigens within the transplanted organ. DSA usually activate the classical pathway of complement within the allograft, and complement activation is believed to be an important cause of tissue injury in AMR. Several new clinical assays may improve our ability to identify patients at risk of AMR. Complement inhibitory drugs have also been tested in selected patients and in small series. Better understanding of the role of complement activation in the pathogenesis of AMR will likely improve our ability to diagnose the disease and to develop novel treatments.
抗体介导的移植排斥反应 (AMR) 是导致长期移植物失功的主要原因,而目前可用的治疗方法对治疗该疾病的疗效有限。AMR 是由与移植器官内抗原结合的供体特异性抗体 (DSA) 引起的。DSA 通常会激活移植物内补体的经典途径,并且补体激活被认为是 AMR 中组织损伤的重要原因。一些新的临床检测方法可能会提高我们识别 AMR 风险患者的能力。补体抑制药物也已在选定的患者和小系列中进行了测试。更好地了解补体激活在 AMR 发病机制中的作用,可能会提高我们诊断疾病和开发新疗法的能力。
