The events following organ transplantation require a reciprocal cell interaction which includes both the conventional host-versus-graft reaction and a graft-versus-host component. With all successful transplantation, both graft and recipient become genetic composites. Where donors were available, chimerism has been confirmed in 30-year kidney-recipient survivors, as well as in several liver and lung recipients. A majority of liver recipients have been able to acquire an immunosuppressant-free state after 10-year survival. Animal models suggest that donor-derived cells may exert a tolerogenic effect.
器官移植后的一系列事件需要细胞间的相互作用,这既包括传统的宿主对移植物反应,也包括移植物对宿主成分。在所有成功的移植中,移植物和受体都成为了基因复合体。在有供体可用的情况下,已经在存活30年的肾移植受者以及一些肝移植和肺移植受者中证实了嵌合体的存在。大多数肝移植受者在存活10年后能够进入无免疫抑制剂状态。动物模型表明,供体来源的细胞可能发挥致耐受性作用。
