| Research Abstract |
CpG oligoDNAs (ODNs) are currently tested in clinical trials as vaccine adjuvants. They have the nuclease-resistant phosphorothioate bond; the immune responses elicited differ according to the CpG ODN sequence and vaccination method. To develop a CpG ODN that can induce plasmacytoid dendritic cell (pDC)-mediated Th1 immunity through the mucosa, we constructed phosphodiester CpG ODN "G9.1" and investigated its usefulness as mucosal adjuvant.
G9.1 increased Th1 immunity in mice and humans. Nasal vaccination of G9.1 with diphtheria toxoid (DT) to mice induced DT-specific mucosal IgA and serum IgG2a/c (Th1-type). Induction of Th1-type Ab depended on pDCs. Combined immunization with a specific Mycobacterium tuberculosis antigen and G9.1 to a model animal, which exhibits week immunity against Mycobacterium tuberculosis infection, augmented the protective immunity. The increase in G9.1 activity with this antigen may be involved in the mechanisms. G9.1 seems to be a promising mucosal adjuvant.
