含有未甲基化CpG基序的合成寡脱氧核苷酸(ODN)触发表达Toll样受体9的细胞(包括人浆细胞样树突状细胞和B细胞)产生以产生Th1和促炎细胞因子为特征的先天性免疫应答。当用作疫苗佐剂时,CpG ODN改善专职抗原呈递细胞的功能,并促进体液和细胞疫苗特异性免疫应答的产生。通过保持ODN和疫苗紧密接近来优化这些效果。CpG ODN的佐剂性质在全身或粘膜施用时观察到,并且在免疫受损的宿主中持续存在。临床前研究表明,CpG ODN提高了针对传染病和癌症的疫苗的活性。临床试验表明,CpG ODN具有良好的安全性,并增加了联合施用疫苗的免疫原性。
Synthetic oligodeoxynucleotides (ODNs) containing unmethylated CpG motifs trigger cells that express Toll-like receptor 9 (including human plasmacytoid dendritic cells and B cells) to mount an innate immune response characterized by the production of Th1 and proinflammatory cytokines. When used as vaccine adjuvants, CpG ODNs improve the function of professional antigen-presenting cells and boost the generation of humoral and cellular vaccine-specific immune responses. These effects are optimized by maintaining ODNs and vaccine in close proximity. The adjuvant properties of CpG ODNs are observed when administered either systemically or mucosally, and persist in immunocompromised hosts. Preclinical studies indicate that CpG ODNs improve the activity of vaccines targeting infectious diseases and cancer. Clinical trials demonstrate that CpG ODNs have a good safety profile and increase the immunogenicity of coadministered vaccines.
