摘要:
Double-stranded short interfering ribonucleic acid (siRNA) are modified to reduce or eliminate their immunostimulatory effect without significantly affecting their gene silencing effect. Modified siRNA include one or more 2' sugar modifications and, optionally, internucleotide linkages on the sense strand. Compositions containing the modified siRNA and methods of making and using the modified siRNA are disclosed. New and previously characterized siRNA can be synthesized to incorporate modifications according to the invention.
摘要(中):
修饰双链短干扰核糖核酸(siRNA)以降低或消除其免疫刺激作用,而不显着影响其基因沉默效应。 修饰的siRNA包括一个或多个2'糖修饰物,并且任选地在有义链上包含核苷酸间键。 公开了含有修饰的siRNA的组合物和制备和使用经修饰的siRNA的方法。 可以合成新的和以前表征的siRNA以掺入根据本发明的修饰。
