ODN 4084-F

Toll-Like Receptor 9 (TLR9) detects unmethylated CpG dinucleotides in bacterial or viral DNA inducing strong immunostimulatory effects. TLR9 activation can be mimicked by synthetic phosphorothioate-stabilized oligodeoxynucleotides (ODN) containing immune stimulatory “CpG motifs”. Recent studies suggest the existence of DNA sequences that can neutralize the stimulatory effect of CpG ODNs.

ODN 4084-F belongs to a new class of inhibitory ODNs [1-2]. It contains an inhibitory DNA motif consisting of two nucleotide triplets, a proximal CCT and a more distal GGG, spaced from each other by four nucleotides. ODN 4084-F is the shortest active inhibitory ODN. ODN 4084-F is linear and a class B (‘broadly-active') inhibitory ODN. ODN 4084-F is potent inhibitor of TLR9-induced B cells and macrophages [3].
