摘要:
目的:探讨移植物中表达趋化因子受体6(CCR6)或CCR7的T细胞数量与异基因造血干细胞移植后急性移植物抗宿主病(GVHD)发生的关系。方法:选取行亲缘异基因造血干细胞移植的52对供受者为研究对象,经重组人粒细胞集落刺激因子动员后,测定并比较骨髓和外周血采集物中CCR6+或CCR7+T细胞的数量,分析输注的各亚群T细胞数量与移植后受者发生Ⅱ-Ⅳ度急性GVHD的关系。结果:动员后,外周血采集物中CD4+CCR6+、CD8+CCR6+、CD4+CCR7+及CD8+CCR7+ T细胞的绝对数量均较骨髓中增多(P<0.05),是骨髓中的15~25倍,但移植物中上述各亚群细胞的绝对数量不是移植后受者发生急性GVHD的危险因素(P>0.05)。结论:移植后受者急性GVHD的发生可能与移植物中CCR6+ 或CCR7+ T细胞的数量无关。
Abstract:
Aim: To detect the quantity of T cell subsets expressing C-C chemokine receptor type 6(CCR6)or CCR7 in the grafts and analyze their correlation with the occurrence of acute graft-versus-host disease(GVHD).Methods: Fifty-two pairs of healthy donor and their recipients with family donor allogenetic hematopoietic stem cell transplantation(allo-HSCT)were included in this study. All the recipients were injectedrecombinant human granulocyte colony-stimulating factor(rhG-CSF)for mobilizing. The quantity of T cells expressing CCR6 or CCR7 in rhG-CSF mobilizedbone marrow grafts(G-BM)and peripheral blood grafts(G-PB)were detected and compared. The correlation of the quantity of each subset cells with the cumulative incidence of grades Ⅱ to Ⅳ acute GVHD in recipients was analyzed.Results: After rhG-CSF mobilization, G-PB had obviously more T cells than G-BM(P<0.05). CD4+CCR6+, CD8+CCR6+, CD4+CCR7+ and CD8+CCR7+ T cells in G-PB were approximately 15-25 times more than those in G-BM. And the absolute counts of the above T cell subsets were not risk factors for acute GVHD(P>0.05).Conclusion: The quantity of T cell subsets may not be related to the occurrence of acute GVHD.
