Abstract:
Objective:To explore the role of TNFSF14 and its receptors LTβR and HVEM in the pathogenesis of virus hepatitis.Methods:Marine fulminant viral hepatitis model was established by infecting mice with MHV-3.Liver tissue destruction in LIGHT KO and WT mice were analyzed by HE staining and ALT levels in serum by automatic biochemical analyzer .The mRNA levels of HVEM and LTβR in the liver and spleen tissues in the indicated time points ( 0 h, 12 h, 24 h, 48 h, 72 h ) were detected by quantitative-PCR.The expression of HVEM and LTβR on PBMC in patients with severe hepatitis were measured by flow cytometry.Results:In the MHV-3-induced murine fulminant hepatitis model ,liver injury in LIGHT KO mice was obviously decreased than that of WT mice,and ALT levels was also significantly lower than that of WT mice (P<0.01).The mRNA of HVEM and LTβR in the spleen were increased significantly after 48 h postinfection with MHV-3 ( P<0.05 );The level of LTβR mRNA in liver was significantly up-regulated in 12 h postinfection with MHV-3(P<0.01).Compared to healthy volunteers,the expression of both HVEM and LTβR on PBMC in patients with severe hepatitis was remarkably enhanced .Conclusion: TNFSF14 and its receptors LTβR and HVEM play a critical role in the pathogenesis of viral fulminant hepatitis .
