Innate immune response mediated by Toll-like receptors (TLRs) has been implicated to be the therapeutic targets for Alzheimer’s disease (AD). TLR9 agonist cytosine-guanosine-containing DNA oligodeoxynucleotides (ODNs) have been shown to be effective in reducing AD pathology in three AD animal models. To interrogate the involvement of TLR9 in AD, we measured the difference in methylation level of CpG probes in the promoter regions of TLR9 and demonstrated that hypermethylation of cg11855705 (p=0.003) and hypomethylation of cg08721301 (p=0.03), and cg22484793 (p=0.03) in postmortem brain tissue from the superior temporal gyrus (STG) region in AD subjects comparing to cognitively normal control subjects. These results provided an independent line of evidence in the potential role of TLR9 in AD pathology.
