| Outline of Final Research Achievements |
We analyzed the expression of TLR7 and other members of the TLR family, including TLR3, TLR4, TLR5, TLR6 and TLR9, and the clinicopathological features of cholangiocarcinoma and pancreatic cancer. TLR7 was highly expressed in both cancers. In addition, TLR3, TLR4, TLR5 and TLR6 were highly expressed in both cancers.
Administration of a TLR7 agonist suppressed cell proliferation in a cholangiocarcinoma cell line and a pancreatic cancer cell line. Furthermore, a TLR7 agonist demonstrated anti-cancer effects in a xenograft mouse model. This study suggests that novel anti-cancer therapies can be developed to target TLR7.
