摘要: CpG ODN是人工合成的具有非特异性免疫刺激的DNA序列,模拟细菌DNA在体内的应答过程,诱发细胞和体液免疫。CpG ODN作为新型免疫增强剂在兽医临床上的应用展现出了巨大的潜力,并在免疫学、药物学和药效学等领域备受关注。然而CpG ODN并不稳定且易被核酸酶酶解,其自身带负电荷,不易结合到细胞表面。因此,CpG ODN如何高效传递并能有效摄取成了新的挑战。纳米传递系统的研究使CpG ODN单独或协同疫苗免疫取得显著疗效,为改善CpG ODN在疫苗研究中的应用拓宽了思路。从CpG ODN纳米佐剂的作用机制、免疫活性、安全性及临床应用等方面进行综述,并对该领域未来的研究方向进行展望,为后续工作提供有益参考。

Abstract: CpG ODN is a synthetic DNA sequence with non-specific immunostimulation which simulates the response process of bacterial DNA in vivo, inducing cellular and humoral immunity. CpG ODN has shown great potential as a novel immunopotentiator in veterinary clinical applications, and has attracted much attention in the fields of immunology, pharmacology and pharmacodynamics. However, CpG ODN is unstable and easily digested by nucleases, which are negatively charged and do not easily bind to the cell surface. Therefore, how to efficiently transfer CpG ODN and effectively ingest it becomes a new challenge. The study of nano-transmission system has achieved significant efficacy for CpG ODN alone or in combination with vaccine immunization, and broadened the thinking for improving the application of CpG ODN in vaccine research. The mechanism of action, immunological activity, safety and clinical application of CpG ODN nanoadjuvant were summarized, and future research directions in this field was prospected, to provide useful reference for follow-up work.
