TLR9 Antagonist - Inhibitory ODN, preference towards mouse
Toll-like receptor 9 (TLR9) recognizes specific unmethylated CpG oligonucleotide (ODN) sequences that distinguish microbial DNA from mammalian DNA.
Studies suggest the existence of DNA sequences that can neutralize the stimulatory effect of CpG ODNs [1].
These sequences are characterized by three consecutive Gs downstream of a C or A, addition of a fourth G (G-tetrads) increases the inhibitory capability.
The most potent inhibitory sequences are (TTAGGG)4 found in mammalian telomeres [2] and ODN 2088 which derives from a stimulatory ODN by replacement of 3 bases [3].
Inhibitory ODNs act by disrupting the colocalization of CpG ODNs with TLR9 in endosomal vesicles without affecting cellular binding and uptake.
