Abstract
BACKGROUND: Human endogenous retrovirus (HER Vs) constitute approximately 8% of the human genome. Induction of HER V transcription is possible under certain circumstances, and may have a possible role in some pathological conditions. Aim of the present study was to verify whether HER V-W and K activation by Epstein Barr Virus (EBV) might occur also in vivo, during EBV infection, in pediatric liver transplant recipients. METHODS: A total of 35 pediatric liver transplant (LT) patients who received LT at the University Hospital City of Science and Health of Turin, Regina Margherita Children's Hospital were included. The samples were grouped in EBV negative and positive. RESULTS: We found that HER V-K, and HER V-W expression levels showed no differences between the two groups (P=0.533 HERV-W and P=0.6017 HERV-K). There was not was a significant difference P=0.1894 and 0.1705 for HERV-W and -K respectively when we compared transplant recipients' group with high EBV viral load vs. others transplant recipients. CONCLUSIONS: Our data suggest that EBV does not facilitate in-vivo HERV activation.
