SUMMARY OF THE INVENTION 0006. It has been discovered that immunostimulatory BACKGROUND OF THE INVENTION properties of specific C-class CpG oligonucleotides with the 0003 Bacterial DNA has immune stimulatory effects to selective inclusion of one or more non-stabilized linkages activate B cells and natural killer cells, but vertebrate DNA between certain nucleotides have significant activity and are does not (Tokunaga, T., et al., 1988.

The 79:682-686: Tokunaga, T., et al., 1984, JNCI 72:955-962: non-stabilized linkages are preferably natural linkages, i.e., Messina, J. P., et al., 1991, J Immunol. 147: 1759-1764; and phosphodiester linkages or phosphodiester-like linkages. A reviewed in Krieg, 1998.

Krieg, (Eds.), John Wiley and relatively susceptible to nuclease digestion. The immuno Sons, Inc., New York, N.Y., pp. 431-448). It is now under stimulatory oligonucleotides of the instant invention include stood that these immune stimulatory effects of bacterial DNA at least one non-stabilized linkage situated between a 5° C. are a result of the presence of unmethylated CpG dinucle and an adjacent 3' G, wherein both the 5°C. and the 3' Gare otides in particular base contexts (CpG motifs), which are internal nucleotides. common in bacterial DNA, but methylated and underrepre 0007. The immunostimulatory oligonucleotides of the sented in vertebrate DNA (Kriegetal, 1995 Nature 374:546 instant invention are useful for inducing a Th1-like immune 549; Krieg, 1999 Biochim. Biophys.

Accordingly, the immunostimulatory oligonucle immune stimulatory effects of bacterial DNA can be mim otides of the instant invention are useful as adjuvants for icked with synthetic oligodeoxynucleotides (ODN) contain vaccination, and they are useful for treating diseases includ ing these CpG motifs. Such CpG ODN have highly stimula ing cancer, infectious disease, allergy, and asthma.
