The present invention provides highly active locked nucleic acid cyclic-dinucleotide (LNA-CDN) immune stimulators that activate DCs via the cytoplasmic receptor known as STING (Stimulator of Interferon Genes). In particular, the LNA-CDNs of the present invention are provided in the form of a composition comprising one or more cyclic dinucleotides that induce human STING-dependent type I interferon production, wherein the cyclic dinucleotides present in the composition have at least one 2′, 4′ locked nucleic acids within the cyclic dinucleotide.
本发明提供了高活性的锁定核酸环二核苷酸(LNA-CDN)免疫刺激剂,通过细胞质受体STING(干扰素
基因刺激剂)激活DCs。具体而言,本发明的LNA-CDNs以一种组合物的形式提供,该组合物包括一种或多种诱导人类STING依赖型I型干扰素产生的环二核苷酸,其中组合物中的环二核苷酸至少有一个2′, 4′锁定核酸。
