Objective To review the research progress of Toll-like receptors (TLRs) signaling and its effects in organ transplantation. Methods The structural and functional features of TLRs and their ligands were summarized,the literatures in recent years about the research progress of TLRs signaling in animal experiment and clinical organ transplantation were reviewed. Results TRLs played an important role in the organ transplantation,the activation of TLRs could activate the specific immune system,and contribute to ischemic reperfusion injury,acute and chronic allograft rejections,and induce the immune tolerance. Early treatment intervention could reduce the activation of TRLs through ischemic reperfusion injury in the organ transplantation,and improve the allograft survival. The efficient immunosuppressive drugs which aimed at the related immunosuppressive target in immune and its signal transduction pathway could reduce ischemic reperfusion injury in the organ transplantation and immune rejection. Conclusions TRLs signaling plays an important role in ischemic reperfusion injury,immune rejection,and immune regulation.
