Inflammation caused by TLR9. TLR9 binds not only DNA originating from bacteria and viruses but also endogenous DNA and triggers signaling cascades related to pro-inflammatory responses. Diseases such as cancer, chronic infection, and lifestyle-related diseases can modulate TLR9 expression. In addition, tissue damage caused by these diseases increases the release of TLR9 agonists. This figure is reproduced from Fukuda et al. (80) with modification.
