CpG oligodeoxynucleotides (CpG ODN) is a synthetic oligodeoxynucleotide, containing unmethylated CpG motifs derived from bacterial DNA, with immunostimulatory activities. Several studies have shown that CpG ODN is able to stimulate cells that express TLR9, initiating an immunomodulatory cascade that culminates in the production of Th1 and proinflammatory cytokines and chemokines. Besides, they also can improve the antigen presenting function of dendritic cells, monocytes and macrophages, induce the proliferation of B cells, stimulate the immunoprotective activity of NK cells, and recruit T cells to the site of ODN administration. These diverse effects of CpG ODN on the host's immune milieu underlie their value as vaccine adjuvants, indicate that CpG ODN has great promise to act as immunotherapeutic agent for treatment of infectious diseases, allergy and cancer.

So far three major classes of CpG ODNs have been identified, based on their structural and biological characteristics, and are designated Type A, Type B, and Type C. Type A ODNs, which feature a central palindromic CpG-containing phosphodiester (PO) structure followed by a phosphorothioate (PS) homopolymeric G-stretch, are robust inducers of interferon-α (IFN-α) production and dendritic cell maturation. Type B ODNs, in contrast, contain a full phosphorothioate backbone with one or more CpG dinucleotides. They strongly activate B cells but stimulate weakly IFN-α secretion. Type C ODNs, combine the properties of both Type A and B, and are characterized by their complete PS backbone and palindromic CpG-containing motifs. Type C ODNs induce strong IFN-α production from pDC and B cell stimulation.
