Abstract:
Objective To explore the relation between activation of TLR4 and liver injury in partial hepatic ischemia/reperfusion (I/R) injury in mice. Methods BALB/c mice were used in a model of partial hepatic I/R injury, the distribution of TLR4 in liver was observed with immunohistochemical stains. The level of plasma ALT and endotoxin in portal vein were measured. TLR4-deficient mice (C3H/Hej) and wild type mice (C3H/Heouj) were used in a model of I/R injury, the hepatic function and serum TNF-? were observed. Results 1. After one hour ischemia the expression of TLR4 protein increased at 1 st, 3 rd h of reperfusion. especially in Kupffer cells, followed by Granno-monocyte and liver sinus epithelial cell; 2. No endotoxemia developed; 3. At 3 rd h of reperfusion, serum TNF-? was significantly higher than sham group [Hej: (152?43)pg/ml vs. (18?10)pg/ml, n=6, t=5.26, P
