The present invention relates to a complexed RNA, comprising at least one RNA complexed with one or more oligopeptides, wherein the oligopeptide has a length of 8 to 15 amino acids and has the empirical formula (Arg)l;(;Lys)m;(His)n;(Orn)o;(Xaa)x with the majority of the residues being selected from Arg, Lys, His, Orn. The invention further relates to a method for transfecting a cell or an organism, thereby applying the inventive complexed RNA. Additionally, pharmaceutical compositions and kits comprising the inventive complexed RNA, as well as the use of the inventive complexed RNA for transfecting a cell, tissue or an organism and/or for modulating, preferably inducing or enhancing, an immune response are disclosed herein.
本发明涉及一种复合 RNA,包括至少一种与一种或多种寡肽复合的 RNA,其中寡肽的长度为 8 至 15 个氨基酸,具有经验式 (Arg)l;(;Lys)m;(His)n;(Orn)o;(Xaa)x,大部分残基选自 Arg、Lys、His、Orn。本发明进一步涉及一种转染细胞或生物体的方法,从而应用本发明的复合 RNA。此外,本文还公开了包含本发明络合 RNA 的药物组合物和试剂盒,以及本发明络合 RNA 用于转染细胞、组织或生物体和/或调节、优选诱导或增强免疫反应的用途。
