To study whether altered and reduced functional capacities of type I and type II IFNs would affect rotavirus-induced diarrhea and viral replication, we obtained signal transducers and activators of transcription 1 (Stat1) knock-out mice (Stat1(-/-)) that lack many IFN-induced responses.

|
Thus, modulating IFN function through the loss of Stat1 caused a defective innate immune response in adult mice but had no effect on rotavirus-induced diarrhea and replication in suckling mice.

|
Furthermore, adult Stat1(-/-), IFN-gamma, and IFN-alpha/beta receptor(-/-) (IFNAR-2(-/-)) mice infected with rotavirus or vaccinated with VP6 vaccine and adjuvant were fully protected against rotavirus shedding following a subsequent challenge with rotavirus.

Plasmid-DNA-activated, TBK1-dependent signalling and the resultant type-I interferon receptor-mediated signalling was required for induction of antigen-specific B and T cells, which occurred even in the absence of innate immune signalling through a well known CpG DNA sensor-Toll-like receptor 9 (TLR9) or Z-DNA binding protein 1 (ZBP1, also known as DAI, which was recently reported as a potential B-form DNA sensor).

Moreover, bone-marrow-transfer experiments revealed that TBK1-mediated signalling in haematopoietic cells was critical for the induction of antigen-specific B and CD4(+) T cells, whereas in non-haematopoietic cells TBK1 was required for CD8(+) T-cell induction.

By interacting with STAT1 and Jak1, the viral P and V proteins prevent the type I interferon receptor (IFNAR) signalling.

The H protein binds to TLR2, which then transduces an activation signal and CD150 expression in monocytes.

To test whether the initial host immune response limits the capacity of mLANA-null virus to traffic to and establish latency in the spleen, we infected type I interferon receptor knockout (IFN-alpha/betaR(-/-)) mice via intranasal inoculation and observed the presence of viral genome-positive splenocytes at day 18 postinfection at approximately 10-fold-lower levels than in the genetically repaired marker rescue-infected mice.

STAT2 mediates innate immunity to Dengue virus in the absence of STAT1 via the type I interferon receptor.

|
To determine the molecular basis of the STAT1-independent pathway, mice lacking STAT1, STAT2, or both STAT1 and STAT2 were infected with a virulent mouse-adapted strain of DENV2.
|
16 |
21379341
|
In the first 72 hours of infection, the single-deficient mice lacking STAT1 or STAT2 possessed 50-100 fold higher levels of viral RNA than wild type mice in the serum, spleen, and other visceral tissues, but remained resistant to DENV-induced death.
|
17 |
21379341
|
In contrast, the double-deficient mice exhibited the early death phenotype previously observed in type I and II IFN receptor knockout mice (AG129), indicating that STAT2 is the mediator of the STAT1-independent host defense mechanism.
|
18 |
21379341
|
Further studies demonstrated that this STAT2-dependent STAT1-independent mechanism requires the type I IFN receptor, and contributes to the autocrine amplification of type I IFN expression.
|
19 |
21379341
|
Examination of gene expression in the spleen and bone marrow-derived macrophages following DENV infection revealed STAT2-dependent pathways can induce the transcription of a subset of interferon stimulated genes even in the absence of STAT1.
|

|
Collectively, these results help elucidate the nature of the poorly understood STAT1-independent host defense mechanism against viruses by identifying a functional type I IFN/STAT2 signaling pathway following DENV infection in vivo.

The Italian BTV L strains, in general, were lethal for both newborn NIH-Swiss mice inoculated intracerebrally and adult type I interferon receptor-deficient (IFNAR(-/-)) mice, while the virulence of the H strains was attenuated significantly in both experimental models.
