, which may be modified by a lipid. The nucleic acid of the invention acts as an immune-stimulating agent inducing the innate immune response. The invention relates further to a pharmaceutical composition (in a first embodiment), each containing an immune-stimulating agent according to the invention in combination with a pharmaceutically active carrier/vehicle (and, optionally, further auxiliary substances, additives and/or further adjuvants). In another embodiment, the inventive nucleic acid is combined with at least one pharmaceutically active component, a pharmaceutically acceptable carrier/vehicle (and, optionally, further auxiliary substances, additives and/or further adjuvants). Accordingly, the present invention is directed to a vaccine, which corresponds to a pharmaceutical composition of the invention (second embodiment), wherein the pharmaceutically active component induces a specific immune response (e.g. an antigen). The present invention relates likewise to the use of a nucleic acid of the invention or a pharmaceutical composition according to the invention for the treatment of infectious diseases, autoimmune diseases, allergies or cancer diseases.
本发明涉及一般式(I):GlXmGn或(II):ClXmCn的核酸,该核酸可以通过脂质进行修饰。本发明的核酸作为一种免疫刺激剂,诱导先天免疫应答。本发明进一步涉及一种药物组合物(在第一实施例中),每种组合物包含根据本发明的免疫刺激剂与药学活性载体/载体(以及可选的进一步辅助物质、添加剂和/或进一步佐剂)的组合。在另一实施例中,创新的核酸与至少一种药学活性成分、药学可接受的载体/载体(以及可选的进一步辅助物质、添加剂和/或进一步佐剂)结合。因此,本发明涉及一种疫苗,该疫苗对应于本发明的药物组合物(第二实施例),其中药学活性成分诱导特异免疫应答(例如抗原)。本发明同样涉及利用本发明的核酸或药物组合物用于治疗传染病、自身免疫疾病、过敏或癌症疾病。
