美国斯托尼布鲁克大学研究人员发现,减毒或无毒力的脊髓灰质炎病毒能有效去除小鼠中的成神经细胞瘤,即使此小鼠接种过脊髓灰质炎疫苗。研究人员将减毒病毒注入12只携带人 CD155基因的转基因小鼠体内的成神经细胞瘤中。随后,这些小鼠接种脊髓灰质炎疫苗。病毒消除了所有小鼠体内的肿瘤,但在随后的6个月内,2只小鼠体内的肿瘤复 Researchers at Stony Brook University in the United States found that attenuated or virulent poliovirus effectively removes neuroblastoma in mice, even though the mice were vaccinated against poliomyelitis. The researchers injected attenuated viruses into neuroblastomas in 12 transgenic mice carrying the human CD155 gene. Subsequently, these mice were vaccinated against poliomyelitis. The virus eliminated tumors in all mice, but within the next 6 months, the tumor complex in 2 mice
