Recent studies showed that CpG DNA, such as bacterial DNA, plasmid DNA and oligodeoxynucleotides (ODN) which all contain unmethylated CpG motifs, could be used for novel vaccine adjuvant to enhance the humoral and cellular immune responses.

• CpG DNA作为一种新型的免疫佐剂是目前分子免疫学研究的热点之一。 CpG DNA是含有CpG基序(CpG motifs)的细菌DNA、质粒DNA和寡核苷酸(ODN)的统称。
