Majority of human solid tumors, when clinically in an advanced stage, is resistant to most of conventional therapies and consequently improved prognosis with a novel strategy is a crucial target in clinical settings. We developed type 5 adenoviruses which replicated preferentially within tumors and then examined the anti-tumor effects. We also modified the adenoviruses of which the receptor-binding site was replaced with that of type 35 adenoviruses, which subsequently increased the infectivity to human tumors due to a high receptor expression in the tumors. We examined a possible advantage to use carrier cells which were infected with such adenoviruses.

大多数人类实体瘤在临床上处于晚期阶段时，对大多数常规疗法具有抗性，因此用新策略改善预后是临床环境中的关键目标。我们开发了5型腺病毒，其优先在肿瘤内复制，然后检查抗肿瘤作用。我们还修饰了腺病毒，其中受体结合位点被35型腺病毒的受体结合位点取代，由于肿瘤中的高受体表达，其随后增加了对人类肿瘤的感染性。我们研究了使用被这种腺病毒感染的载体细胞的可能优点。
