摘要:

[摘要] 目的:探索联合磁柱分选技术和CMV连锁状多聚体磁珠是否能够纯化CMV特异性CD8+ T细胞,从而促进CMV感染性疾病的过继性免疫治疗。方法:是运用CMV连锁状多聚体PE和磁珠复合物标记CMV特异性CD8+ T细胞,然后用MS磁柱分选,从HLA-A2/CMV血清阳性的健康志愿者的周围血标本中纯化CMV特异性CD8+ T细胞。为了达到最佳的纯化效果,分别将标记后的标本进行一次和两次MS磁柱分选,比较纯化后的CMV特异性CD8+ T细胞的纯度。结果:通过MS磁柱分选技术的纯化,CMV特异性CD8+ T细胞的最高纯度达到90.45%。经过一次和两次MS磁柱分选后,CMV特异性CD8+ T细胞的纯度有显著差异,但经过两次磁柱分选较一次分选的细胞丢失严重。结论:磁柱分选技术纯化CMV特异性CD8+ T细胞效果良好,有利于CMV疾病的过继性免疫治疗。

Abstract: Objectives To investigate whether the technology of MS column and the complex of CMV streptamer PE-magnetic beads could offer the advantage of the purification of CMV-specific CD8+ T cells, therefore benefit for the adoptive immunotherapy of CMV disease. Methods CMV-specific CD8+ T cells were selected by magnetic column from the peripheral blood of HLA-A2/CMV sero-positive healthy donors by using the complex of CMV-streptamer PE and magnetic beads labeling. For best results, we compared the advantage of purification by using MS column between two column selection with one column selection. Results After positive selection by MS column, an increase with up to 90.45% purity was achieved for CMV-specific CD8+ T cells. The samples had a signification different on the purifity of selected T cells when purificated by different times of MS column selection, but the loss of CMV-specific CD8+ T cells is severe when purificated by two column selection. Conclusion It is concluded that the technology of MS column could be used to purify CMV-specific CD8+ T cells for adoptive immunotherapy.
