Toll-like receptor 4 signaling pathway mediates both liver and kidney injuries in mice with hepatorenal syndrome

Our study established BDL, UUO, and BDL + UUO models, providing a novel idea for analyzing liver and kidney diseases. It is highlighted that the kidney injury accelerated the aggravation of HRS via inflammatory response, which could be protected by inhibiting the TLR4 signaling pathway. We believed that targeting TLR4 was a promising therapeutic strategy for protecting both liver and kidney functions in patients with HRS.
