ABSTRACT
Objective:
To explore the role of TLR4 in the process of lower limb ischemia-reperfusion injury.Methods:
Ischemia Reperfusion injury modelin this study,the model of lower limb ischemia-reperfusion was established by rubber band wound method,C57BL / 6J mice were randomly divided into model control group(IR) and ischemia-reperfusion group(IR);TLR4 experimentThe mice models of ischemia reperfusion were divided into wild type (WT) model group and TLR4 knock out (TLR4-/-) model group;The expressions of TLR4 and HMGB1,TNF-α and IL6 were detected by RT-PCR and immunohistochemistry.The apoptosis of vascular wall was detected by TUNEL.Results:
The expression of TLR4,HMGB1,TNF-α,IL6 in the IR group was significantly higher than that in the control group (P<0.01).After TLR4 knockout,the expression of inflammatory factors and apoptosis in IR group was significantly reduced (P<0.01).Conclusion:
TLR4 mediates inflammatory response and induces apoptosis in lower limb ischemia reperfusion injury in mice.
