摘要：

Hepatitis C virus(HCV) infects approximately 180 million people worldwide. Significant progress has been made since the establishment of in vitro HCV infection models in cells. However, the replication of HCV is complex and not completely understood. Here, we found that the expression of host prion protein(Pr P) was induced in an HCV replication cell model. We then showed that increased Pr P expression facilitated HCV genomic replication. Finally, we demonstrated that the KKRPK motif on the N-terminus of Pr P bound nucleic acids and facilitated HCV genomic replication. Our results provided important insights into how viruses may harness cellular protein to achieve propagation.
