摘要
Liver ischemia-reperfusion (I/R) injuries are significant clinical challenges implicated in various hepatic surgical procedures and transplantations. Associated with varying degrees of insult, the hallmark of I/R is the excessive inflammatory response potentiated by the host immune system. Toll-like receptors (TLRs), known to play an important role in pathogen-derived inflammation, are now thought to participate in I/R injury-derived inflammation signaling pathways. Endogenous particles (proteins, cytokines, nucleic acids) that are released from damaged host cells bind to TLR2, TLR4, and TLR9, resulting in even further injury by subsequent inflammatory reactions and activation of the innate immune system. This review aims to systematically examine the current literature about TLR signaling mechanisms, allowing for a greater understanding of the precise role of TLRs in hepatic I/R injuries.
