    • A nucleic acid delivery system that offers, in one system, a combination of high encapsulation efficiency, rapid release kinetics and preservation of DNA in supercoiled form is provided. The nucleic delivery system comprises nucleic acid molecules, such as deoxyribonucleic acid (DNA), encapsulated in biodegradable microspheres, and is particularly suited for delivery DNA vaccines. The ivnention futher provides a method for encapsulating nucleic acid molecules in microspheres. The invention additionally provides a composition comprising nucleic acid molecules encapsulated in microspheres produced by a method of the invention, and a method for delivering a nucleic acid molecule to a subject. The invention futher provides an adjuvant for modulating the immunostimulatory efficacy of microspheres encapsulating nucleic acid molecules comprising an aminoalkyl glucosaminide 4-phosphate (AGP). The invention also provides a method for modulating the immunostimulatory efficacy of microspheres encapsulating nucleic acid molecules.
    • 提供了在一个系统中提供高封装效率,快速释放动力学和超螺旋形式的DNA保存的组合的核酸递送系统。 核酸递送系统包含核酸分子,例如包封在可生物降解的微球中的脱氧核糖核酸(DNA),特别适用于递送DNA疫苗。 另外,提供了一种将核酸分子包封在微球体中的方法。 本发明另外提供包含通过本发明的方法制备的包封在微球体中的核酸分子的组合物和将核酸分子递送至受试者的方法。 本发明还提供了用于调节包含氨基烷基葡糖苷-4-磷酸(AGP)的核酸分子的微球的免疫刺激功效的佐剂。 本发明还提供了调节包封核酸分子的微球的免疫刺激功效的方法。
