In the comparison between genotypes, it was found that 1b-NS5As exerted more profound inhibitory effects on IFN activity than 2a-NS5As. The replication of the 2a-NS5A-containing replicons was more sensitive to IFN treatment than that of the 1b-NS5A-containing replicons. By domain swapping, we found the V3 and the C-terminus regions were responsible for the differential anti-IFN effects between genotypes.

To understand the infectivity by porcine endogenous retrovirus with porcine skin fibroblast cell in vitro and in vivo, porcine skin fibroblast cell established by our laboratory were co-cultured with neo/HEK293 cell for the infection of RERV in vitro, and were subcutaneously transplantated to SCID (severe combined immuno-deficiency) mice for the infection of PERV in vivo, laying the foundation for valuation of biologic safety of xenotrans-plantation. The event of neo/HEK293 cells infected by PERV occurred during co-culture of porcine skin fibroblast cells with neo/HEK293 cells, expanding the rang of the infection of porcine endogenous retrovirus. Afterpig cells transplantated subcutaneously in SCID mice, the microchimerism (78.57%) of pig cells occurred widel, and there was phenomena of integration of PERV provirus (85.71%) in several organs or tissues remote from the injected sites, indicating infection of PERV in SCID mice in vivo. yet, there is no evidence of active viral replication in analysis of PERV env RNA of these tissues or organs.
