Popis: Seneca Valley virus (SVV) or commonly known as senecavirus A, is one of the picornavirus that is associated with vesicular disease and neonatal mortality in swine herds. Our previous study found that SVV replicates extremely faster in porcine Instituto Biologico-Rim Suino-2 (IBRS-2) cells than that in porcine kidney-15 (PK-15) cells. However, the underlying mechanism remains unknown. In this study, we comprehensively compared the expression features between IBRS-2 cells and PK-15 cells in response to SVV infection by an unbiased high-throughput quantitative proteomic analysis. We found that the innate immune response–related pathways were efficiently activated in PK-15 cells but not in IBRS-2 cells during SVV infection. A large amount of interferon (IFN)-stimulated genes were induced in PK-15 cells. In contrast, no IFN-stimulated genes were induced in IBRS-2 cells. Besides, we determined similar results in the two cell lines infected by another porcine picornavirus foot-and-mouth disease virus. Further study demonstrated that the Janus kinase signal transducer and activator of transcription signaling pathway was functioning properly in both IBRS-2 and PK-15 cells. A systematic screening study revealed that the aberrant signal transduction from TANK-binding kinase 1 to IFN regulatory factor 3 in the retinoic acid–inducible gene I–like receptor signaling pathway in IBRS-2 cells was the fundamental cause of the different innate immune response manifestation and different viral replication rate in the two cell lines. Together, our findings determined the different features of IBRS-2 and PK-15 cell lines, which will help for clarification of the pathogenesis of SVV. Besides, identification of the underlying mechanisms will provide new targets and an insight for decreasing the viral clearance rate and probably improve the oncolytic effect by SVV in cancer cells.
Graphical Abstract
Highlights • Divergent innate immune responses were triggered by SVV in IBRS-2 and PK-15 cells. • SVV induced higher levels of type I IFN in PK-15 cells than in IBRS-2 cells. • IBRS-2 cell line has an aberrant RLR pathway but an intact type I IFN pathway. • TBK1-mediated antiviral signal transduction was dysfunctional in IBRS-2 cells.
In Brief Both IBRS-2 and PK-15 cells have been widely used for porcine picornavirus research. However, the virus replicates faster and causes severer CPE in IBRS-2 cells than in PK-15 cells, and the underlying mechanism remains unknown. Proteomic analyses suggested that the RLR pathway was in a dysfunctional state in IBRS-2 cells. We finally determined that the disabled signal transduction from TBK1 to IRF3 in IBRS-2 cells was the fundamental cause of dysfunction of the RLR pathway during porcine picornavirus infection.
