Loss of immunity‐supported senescence enhances susceptibility to hepatocellular carcinogenesis and progression in Toll‐like receptor 2‐deficient mice
Heng Lin, Jun Yan, Ziyan Wang, Fang Hua, Jiaojiao Yu, Wei Sun, Ke Li, Hong Liu, Hongzhen Yang, Qi Lv, Jianfei Xue, Zhuo‐Wei Hu – 1 August 2012 – Hepatocellular carcinoma (HCC) is a complication at the endstage of chronic inflammatory liver diseases with dismal prognosis. Targeting of Toll‐like receptor (TLR) 2 attenuates tumor metastases; we hypothesized that blocking TLR2 might also play a crucial role in reducing hepatocarcinogenesis. Surprisingly, we found that the genetic deletion of TLR2 increased susceptibility to diethylnitrosamine (DEN), a genotoxic carcinogen that can induce HCC.
