Infection with Classical Swine Fever Virus Induces Expression of Type III Interferons and Activates Innate Immune Signaling.

ABSTRACT: Classical swine fever virus (CSFV) commonly infects the lymphatic tissues and immune cells of pigs and could cause a lethal disease in the animals. The process and release of cytokines like type III interferons (IFNs) is one of the important responses of the host innate immunity to viral infection. However, little information is available about type III IFN response to the CSFV infection. In this study, we investigated the expression of type III IFNs including interleukin-28B (IL-28B) and IL-29 in PK-15 cells and pigs following CSFV infection. We found that infection with CSFV was able to induce expression of IL-28B and IL-29 in PK-15 cells, although the increased levels of type III IFNs were limited. Importantly, up-regulation of IL-28B and IL-29 was further observed in CSFV infected anim
