Abstract:
摘要 目的 探讨利用人外周血单核细胞制备树突状细胞(dendritic cell, DC)疫苗过程中,使用重组人粒细胞集落刺激因子(recombinant human granulocyte colony-stimulating factor,rhG-CSF)和重组人粒细胞巨噬细胞集落刺激因子(recombinant human granulocyte/macrophage colony-stimulating factor, rhGM-CSF)进行动员的临床应用可行性,并比较两者作为动员试剂的优劣。方法 对2011年8月至2013年12月中国人民解放军第81医院肿瘤生物治疗科进行DC疫苗治疗的恶性肿瘤患者134例进行随机分组,其中rhG-CSF动员者69例,rhGM-CSF动员者65例。rhG-CSF动员组在血细胞分离机采集前1天行rhG-CSF皮下注射3 μg/(kg·d),rhGM-CSF动员组在血细胞分离机采集前1天行rhGMCSF皮下注射3 μg/(kg·d)。比较两组动员前后血常规变化的差异;分析两组采集终产品中单个核细胞(mononuclear cell, MC)数量及表型,检测体外培养所得DC的数量、表型及细胞因子的表达。结果 动员后rhGM-CSF动员组单核细胞增高值高于rhG-CSF动员组(P≤0.001),但中性粒细胞计数增高值低于rhG-CSF动员组(P≤0.001),其余血常规项目两者差异无统计学意义。rhGMCSF动员组采集终产品中单个核细胞数量高于rhG-CSF动员组(P=0.046),而CD14+单核细胞的比例两组差异无统计学意义。rhGM-CSF动员组最终诱导所得DC数量高于rhGCSF动员组(P=0.011),且DC细胞表面分子HLA-DR的表达高于rhG-CSF动员组(P=0.001),其余CD80、CD86,CD83、CD11C、CD54表达两组差异无统计学意义。两组DC细胞Th1型和Th2型细胞因子的表达差异都无统计学意义。结论 在用人外周血单核细胞制备DC疫苗的过程中,使用rhGM-CSF动员比rhG-CSF更有优势
