One aspect of the present invention relates to a double stranded iRNA agent comprising an antisense strand which is complementary to a target gene; a sense strand which is complementary to said antisense strand; and one or more lipophilic moieties conjugated to one or more internal positions on at least one strand, optionally via a linker or carrier, which provides for targeting to, and uptake by, tissues and cells of the CNS, and in particular the striatum. Another aspect of the invention relates to a method of gene silencing in tissues and cells of the CNS, and in particular the striatum, that includes administering to a tissue/cell or a subject in need thereof a therapeutically effective amount of the lipophilic moieties-conjugated double-stranded iRNAs.
本发明的一个方面涉及双链iRNA剂,包括一个与目标基因互补的反义链;一个与该反义链互补的正义链;以及一个或多个脂溶性基团,通过连接物或载体与至少一条链上的一个或多个内部位置结合,从而实现对中枢神经系统组织和细胞,特别是纹状体的靶向和摄取。本发明的另一个方面涉及一种在中枢神经系统组织和细胞,特别是纹状体中基因沉默的方法,包括向需要治疗的组织/细胞或受试者中注射足够疗效量的脂溶性基团结合的双链iRNA。
