Enhanced Replication of Hepatitis E Virus Strain 47832c in an A549-Derived Subclonal Cell Line.

ABSTRACT: Hepatitis E virus (HEV) is a human pathogen with increasing importance. The lack of efficient cell culture systems hampers systematic studies on its replication cycle, virus neutralization and inactivation. Here, several cell lines were inoculated with the HEV genotype 3c strain 47832c, previously isolated from a chronically infected transplant patient. At 14 days after inoculation the highest HEV genome copy numbers were found in A549 cells, followed by PLC/PRF/5 cells, whereas HepG2/C3A, Huh-7 Lunet BLR and MRC-5 cells only weakly supported virus replication. Inoculation of A549-derived subclone cell lines resulted in most cases in reduced HEV replication. However, the subclone A549/D3 was susceptible to lower virus concentrations and resulted in higher virus yields as compared to parent
