The invention refers to a recombinant oncolytic RNA Newcastle Disease Virus for the treatment of a proliferative disease, comprising at least one transgene coding for an avian cytokine, wherein the recombinant oncolytic RNA Newcastle Disease Virus is obtainable from a velogenic or mesogenic oncolytic RNA Newcastle Disease Virus. Virus-mediated expression of the cytokine in the natural host cells leads to a reduced pathogenicity of the virus for avian species. Furthermore the virus genome can encode binding proteins, prodrug-converting enzymes or/and proteases. The selective expression of these molecules in virus-infected tumor cells increases the anti-tumor effect of the virus.
本发明涉及一种用于治疗增殖性疾病的重组溶瘤RNA新城疫病毒,该病毒包含至少一个编码禽细胞因子的转基因,其中重组溶瘤RNA新城疫病毒可从绒源性或介源性溶瘤RNA新城疫病毒中获得。病毒介导的细胞因子在天然宿主细胞中的表达可降低病毒对禽类的致病性。此外,病毒基因组可编码结合蛋白、原药转化酶或/和蛋白酶。在病毒感染的肿瘤细胞中选择性地表达这些分子可增强病毒的抗肿瘤作用。
