摘要
异基因骨髓移植是治疗多种血液系统恶性肿瘤的有效方法,治疗效果主要归功于移植物抗白血病效应(graft-versus-leukemia,GVL),它可以清除残存肿瘤细胞,提高生存率。然而,GVL与骨髓移植的一大并发症——移植物抗宿主病(graft-versus-host disease,GVHD)紧密相连。现代科学研究揭示了急性GVHD的病理过程,在此过程中有一些机制发挥着抗肿瘤作用。曾经的观念认为,GVHD和GVL是相互关联、密不可分的,但最近的研究显示,虽然尚不能采取某种方式将这两者截然分开,但合理利用一些免疫细胞、细胞因子、信号通路、组织抗原,可以达到既降低GVHD又保留GVL的目的。
Allogeneic bone marrow transplantation(allo-BMT) is now an effective treatment for multiple maglinant hematological tumors. Graft-versus-leukemia (GVL) after allo-BMT can eliminate residual tumor cells and improve survivals, while it is closely related with severe graft-versus-host diseases(GVHD). Recent studies clarified the pathological changes of acute GVHD, being different from the old concepts. Now many scientists reached an agreement that although we can't separate GVHD and GVL completely, we can take some advantage of some immune cells, chemokines, cell signals, tissue antigens to reduce GVHD as well as remain GVL.
