ABSTRACT
<p><b>OBJECTIVE</b>To compare the expression of C-C chemokine receptor type 5 (CCR5) on T cells between bone marrow grafts (G-BM) and peripheral blood grafts (G-PB) nobilized by recombinant human granulocyte colony-stimulating factor (rhG-CSF), and to analyze the correlation of CCR5+ T lymphocyte expression in the grafts with the occurrence of acute GVHD.</p><p><b>METHODS</b>Forty-six healthy donor and their recipient pairs of related allogeneic hematopoietic stem cell transplantation (allo-HSCT) were enrolled in this study. All the recipients were received the infusion of G-BM and G-PB. The relative proportion and quantity of CCR5+ T cell subset in G-BM and G-PB were detected and compared. Then the correlation of the quantity of infused CCR5+ T cells with the occurrence of acute GVHD was analyzed.</p><p><b>RESULTS</b>After mobilization, the proportions of CD4+ CCR5+ and CD8+ CCR5+ T cells occupying T cells in G-PB were both lower than those in G-BM. However, the absolute counts in G-PB were 15-25 times more than those in the bone marrow. And the absolute counts could not predict the occurrence of acute GVHD after transplantation (P>0.05).</p><p><b>CONCLUSION</b>The difference of CCR5+ subsets between G-PB and G-BM may partially explain that grafts from different sources have different immunologic characteristics. Besides, the quantity of CCR5+ T cells in the grafts are not related with the occurrence of acute GVHD. However, the relative proportion of CCR5+ T cell subset in the grafts may be predictive of acute GVHD.</p>
