干细胞移植后的病毒感染是最常见的死亡原因，尤其是在脐带血（CB）移植（CBT），CB不包含相当数量的病毒有经验的T细胞可以保护收件人感染。1 -我们和其他人表明，病毒特异性CTL产生的血清学阳性的捐助者，并注入到收件人的安全和保护。5-8然而，直到最近，病毒特异性T细胞不能产生脐带血，可能是由于病毒特异性记忆T细胞的缺乏。 为了更好地模仿体内吸幼稚T细胞的条件，我们建立了一个方法，该方法使用CB来源的树突状细胞（DC）的腺病毒载体（Ad5f35pp65）含有的免疫CMV抗原病毒pp65转，因此驱动T细胞特异性对巨细胞病毒和腺病毒。在开始，我们利用这些马捕获区议会，以及CB来源的T细胞的细胞因子的存在下，IL-7，IL-12和IL-15。[10]在所述第二刺激我们使用EBV-转化的B细胞，或EBV-LCL，同时表达潜在的和裂解EB病毒抗原。 ad5f35pp65转导的EBV-LCL是用于刺激的T细胞中的IL-15的存在，在第二次刺激。后续的刺激使用Ad5f35pp65转导的EBV-LCL和IL-2。 从50×10 6 CB单核细胞中，我们能够产生向上的150×10 6病毒特异性T细胞，裂解抗原脉冲的目标和释放细胞因子响应于抗原刺激11将这些细胞在GMP兼容的方式制造，使用仅分馏脐带血单元分数的20％，并已被翻译供临床使用。
