Abstract
Bacterial DNA and its synthetic immunostimulatory oligodeoxynucleotides’ analogs (ISS-ODN or CpG motifs) are potent stimulators of both innate immunity and specific adaptive immune responses (1–5). Bacterial DNA and ISSODNs directly activate monocytes/macrophages, dendritic cells, natural killer (NK) cells and B cells (6–10), induce the production of proinflammatory cytokines (e.g., IL-6, IL-12, IFNs, TNFa) (4,6,7,11,12), and upregulate the expression of MHC I, MHC II and co-stimulatory molecules (9,13). In animal studies, ISS-ODNs exhibit strong Th1 (2,14–18) and mucosal adjuvanticity to a wide range of antigens (2,3,14,19–26) or allergens (27–30). Furthermore, pretreatment with ISS-ODN, even without concomitant administration of the relevant antigens, can afford protection (for about 2 wk) against subsequent infection with intracellular pathogens (31–35), indicating activation of innate immunity.
