Introduction: Infectious pancreatic necrosis virus (IPNV) is a pathogen important that affects predominantly salmonids. The type I interferon alpha system has a crucial role in the first line of defense against IPNV infection. IFN-I(α) activation triggers the signaling pathway JAK-STAT, binding to their receptors results in the rapid phosphorylation of STATs a critical step for the nuclear translocation to induce the interferon stimulated genes (ISGs).

Objective: our purpose was to investigate if the IFN-I(α) signaling pathway is affected by IPNV strains of different infectivity levels. Methods: We used two IPNV isolated (VR-299 and Sp) to infect RTG-2 cells. Total RNA was isolated using the commercial kit for determine to VP2 expression and ISGs using qRT-PCR. Western Immunoblotting analysis was carried out for determine the 701 STAT1(α/β) phosphorylation into infected cells. Results: Hence, a higher virulence strain is not associated with a greater blocking effect for interferon signaling. Furthermore, the activation of Y701-STAT1 (α/β) was significantly increased in serotype Sp virus infected cells compared with serotype VR-299 virus infected cells, indicating that IPNV inhibits IFN signaling pathway. Conclusions: As concluded, IPNV does not block the phosphorylation of 701-tyrosine STAT1 (α/β) stimulated by IFN-I(α), contrary to other RNA viruses.
