ABSTRACT
The aim of study was to investigate the modulation effect of recombinant human granulocyte colony-stimulating factor (rhG-CSF) on adhesion molecule expression of memory T lymphocyte in the bone marrow grafts. rhG-CSF was administered in 41 donors by subcutaneous injection for 5 consecutive days. Bone marrow grafts were collected on day 4. The percentages of CD4+ and CD8+, and the expressions of CD49d, CD54, CD62L and CD11a on donor T cells of steady state-bone marrow grafts (SS-BM, n=11) and rhG-CSF primed bone marrow (G-BM, n=30) were analyzed by using multi-color flow cytometry. The results indicated that the percentages of CD4+ and CD8+ T cells were significantly lower in G-BM than those in SS-BM (p<0.05). There were no significant differences in the percentages of memory CD4+ and CD8+ T cells between SS-BM and G-BM (p>0.05). The expressions of CD49d on CD4+ and CD8+T cells were significantly lower in G-BM than that in SS-BM (p<0.05). Compared with SS-BM, the expressions of CD54 on CD4+, memory CD4+ T cells and CD8+ T cells were significantly lower in G-BM (p<0.05). The expressions of CD62L on CD4+ and CD8+ T cells and memory T cells were all significantly lower in G-BM (p values were all less than 0.001). The expressions of CD11a on CD4+, memory CD4+ T cells were significantly lower in G-BM than that in SS-BM (p<0.05). There were no significant differences in the expression of CD11a on CD8+, memory CD8+ T cells between SS-BM and G-BM (p>0.05). It is concluded that the expression of cell adhesion molecules on the CD4+ and CD8+ T cells in G-BM is down-regulated after rhG-CSF treatment of healthy donors.
