    • A gene delivery vehicle having been provided with at least a tissue tropism for cells selected from the group of smooth muscle cells, endothelial cells, and/or liver cells. The tissue tropism is generally provided by a virus capsid, such as one comprising protein fragments from at least two different viruses, such as two different adenoviruses, including adenovirus of subgroup C or subgroup B (for example, adenovirus 16). The protein fragments can comprises a tissue tropism determining fragment of a fiber protein derived from a subgroup B adenovirus. Also, cells for producing such gene delivery vehicles and pharmaceutical compositions containing said gene delivery vehicles. Further, a method of delivering nucleic acid to cells such as smooth muscle cells and/or endothelial cells which involves administering to the cells an adenovirus capsid having proteins from at least two different adenoviruses and wherein at least a tissue tropism determining fragment of a fiber protein is derived from a subgroup B adenovirus. Particular construct are also disclosed.
    • 具有至少一种选自平滑肌细胞,内皮细胞和/或肝细胞的细胞的组织嗜性的基因递送载体。 组织向性通常由病毒衣壳提供,例如包含来自至少两种不同病毒的蛋白质片段的病毒衣壳,例如两种不同的腺病毒,包括亚组C或亚组B的腺病毒(例如,腺病毒16)。 蛋白质片段可以包含衍生自亚组B腺病毒的纤维蛋白质的组织向性确定片段。 此外,用于产生这种基因递送载体的细胞和含有所述基因递送载体的药物组合物。 此外,将核酸递送到诸如平滑肌细胞和/或内皮细胞的细胞的方法,其涉及向细胞施用具有来自至少两种不同腺病毒的蛋白质的腺病毒衣壳,并且其中至少一种纤维蛋白质的组织向性确定片段 来源于亚组B腺病毒。 还公开了特定的构建体。

    • Adenoviral vectors with a deletion of the E3 region such that the remaining E3 region reduces the TNF response of a host mammalian cell infected with the virus. The portion of the E3 region remaining in these vectors encodes the 14.7 kD protein, and may also contain a deletion of at least the E1a promoter. These partially deleted E3 vectors will inhibit the host cell's immune response so that the infected cell will live longer. Any non-adenoviral gene expressed from these vectors in the infected cell will be produced for a longer length of time and achieve a higher concentration than when adenoviral vectors not expressing function 14.7 kD protein are used. These 14.7 kD expressing adenoviral vectors will be useful for gene therapy and especially in cancer gene therapy where the non-adenoviral DNA sequence being expressed are preferably cytokine genes, such as IL-1, and suicide genes, such as HSV-tk. The vectors also are useful for antisense therapy.
    • 具有E3区缺失的腺病毒载体使得剩余的E3区降低了感染病毒的宿主哺乳动物细胞的TNF反应。 保留在这些载体中的E3区域的部分编码14.7kD蛋白,并且还可以含有至少E1a启动子的缺失。 这些部分缺失的E3载体将抑制宿主细胞的免疫应答,使感染的细胞寿命更长。 在感染细胞中从这些载体表达的任何非腺病毒基因将产生更长的时间长度,并且比使用不表达14.7kD蛋白质的腺病毒载体时获得更高的浓度。 这些14.7kD表达的腺病毒载体可用于基因治疗,特别是在癌基因治疗中,其中表达的非腺病毒DNA序列优选为细胞因子基因,如IL-1,以及自杀基因,如HSV-tk。 载体也可用于反义治疗。
