Expression of type I interferon-induced antiviral state and pro-apoptosis markers during experimental infection with low or high virulence bovine viral diarrhea virus in beef calves

Summary: | ► IFN-α and -β were upregulated 5 days post infection with BVDV-2 but not with BVDV-1. ► BVDV infection (high or low virulence) upregulated type I interferon-induced genes. ► BVDV-1 infection induced higher expression of OAS-1 and ISG-15 than BVDV-2 infection. ► Upregulation of caspase-8 and -9 was only observed in calves infected with BVDV-1.
The objective of this study was to compare the mRNA expression of host genes involved in type-I interferon-induced antiviral state (IFN-α, IFN-β, Mx-1, PKR, OAS-1 and ISG-15), and apoptosis (caspase-3, -8, and -9), after experimental infection of beef calves with low or high virulence noncytopathic (ncp) bovine viral diarrhea virus (BVDV) strains. Thirty BVDV-naïve, clinically normal calves were randomly assigned to three groups. Calves were intranasally inoculated with low (LV; n=10, strain SD-1) or high (HV; n=10, strain 1373) virulence ncp BVDV or BVDV-free cell culture medium (Control, n=10). Quantitative RT-PCR was used to determine the target gene expression in tracheo-bronchial lymph nodes and spleen 5 days after infection. Interferon-α and -β mRNA levels were up-regulated in tracheo-bronchial lymph nodes (P |
