The present disclosure describes the generation and the use of Ad variants (Ad) possessing any combination of mutations in genes that code for the hexon, penton, fiber, and non-structural proteins, where simultaneous modification of hexon and penton are made to avoid the trapping of Ad in the liver and to reduce toxicity after intravascular virus administration. Such liver de-targeted Ad can be useful tool for selective and specific gene delivery to extra-hepatic tissues and cells, including disseminated metastatic cancer cells.
本公开内容描述了在编码 hexon、penton、纤维和非结构蛋白的基因中具有任意突变组合的 Ad 变体(Ad)的产生和使用,其中同时对 hexon 和 penton 进行了修饰,以避免 Ad 在肝脏中被捕获,并降低血管内病毒给药后的毒性。这种肝脏去靶向 Ad 可作为一种有用的工具,用于向肝外组织和细胞(包括扩散转移的癌细胞)进行选择性和特异性基因递送。
