Although dsRNA is a virus-specific signature and a ligand for human Toll-like receptor 3 (TLR3), largely uncharacterized multiple pathways associate virus-mediated IFN-beta induction.
|
22 |
14575692
|
The kinetics experiments with the laboratory MV strain revealed that TLR3 was induced late compared to IFN-beta and required new protein synthesis.
|
23 |
14575692
|
Furthermore, neutralizing antibodies against IFN-beta or IFNAR (Interferon-alpha/beta receptor) suppressed MV-induced TLR3 induction, indicating that type I IFN, IFN-alpha/beta, is critical for MV-mediated TLR3 induction.
|
24 |
14575692
|
Yet, a recently identified virus-inducible IFN, the IFN-lambda, did not contribute to TLR3 expression.
|
25 |
14575692
|
The ISRE, a recently reported site for IFN-beta induction, but not STAT binding site, located around -30bp of TLR3 promoter responded to MV to induce TLR3 expression.
|
26 |
14575692
|
This further indicates the importance of type I IFN for TLR3 up-regulation in the case of viral infection.
|
27 |
14575692
|
In HeLa and MRC5 cells, augmented production of IFN-beta was observed in response to dsRNA when TLR3 had been induced beforehand.
|
28 |
14575692
|
Thus, the MV-induced expression of TLR3 may reflect amplified IFN production that plays a part in host defense to viral infection.

Type I IFN negatively regulates CD8+ T cell responses through IL-10-producing CD4+ T regulatory 1 cells.
|
30 |
15611232
|
We used vaccine-induced, antiviral CD8(+) T cell responses in IFN-beta (IFN-beta(-/-))- or type I IFN receptor (IFNAR(-/-))-deficient mice to study immunomodulating effects of type I IFN that are not complicated by the interference of a concomitant virus infection.
|
31 |
15611232
|
Compared with normal B6 mice, IFNAR(-/-) or IFN-beta(-/-) mice have normal numbers of CD4(+) and CD8(+) T cells, and CD25(+)FoxP3(+) T regulatory (T(R)) cells in liver and spleen.
|
32 |
15611232
|
IFN-gamma and TNF-alpha production and clonal expansion of specific CD8(+) T cells from normal and knockout mice are similar.
|
33 |
15611232
|
CD25(+)FoxP3(+) T(R) cells down-modulate vaccine-primed CD8(+) T cell responses in normal, IFNAR(-/-), or IFN-beta(-/-) mice to a comparable extent.
|
34 |
15611232

IFNAR- and IFN-beta-deficient mice generate 2- to 3-fold lower numbers of IL-10-producing CD4(+) T cells after polyclonal or specific stimulation in vitro or in vivo.
|
36 |
15611232
|
CD8(+) T cell responses are thus subjected to negative control by both CD25(+)FoxP3(+) T(R) cells and CD4(+)IL-10(+) T(R1) cells, but only development of the latter T(R) cells depends on type I IFN.

The majority of glioblastoma multiforme (GBM) tumors (80%) overexpress interleukin-13 receptor alpha2 (IL-13Ralpha2), but there is no expression of IL-13Ralpha2 in normal brain.
|
64 |
18665158
|
MV-GFP-H(AA)-IL-13 was generated from the Edmonston-NSe vaccine strain, by displaying human IL-13 at the C-terminus of the H protein, and introducing CD46 and signaling lymphocyte activation molecule (SLAM)-ablating mutations in H.

Our results indicate that the RV expressing IFN-beta (IFN+) is highly attenuated when compared to control RV and demonstrate that the expression of IFN-beta reduces viral replication approximately 100-fold.
|
68 |
18945463
|
Despite the decrease in replication, those mice immunized with the IFN+ RV had a significantly greater number of activated CD8+ T cells.
|
69 |
18945463
|
The increased activation of CD8+ T cells was dependent on IFN-beta signaling, as we saw no difference following infection of IFNAR-/- mice.
|
70 |
18945463
|
Although mice immunized with IFN+ have a greater primary immune response than controls, immunized mice that were challenged with vaccinia-expressing Gag had no significant difference in the number or functionality of CD8+ T cells.
|
71 |
18945463

C57BL/6-background wild type (WT), IFN-alpha receptor-1 (IFN-alphaR1)(-/-) or IFN-gamma(-/-) mice bearing syngeneic CNS GL261 glioma received subcutaneous (s.c.) vaccinations with synthetic peptides encoding CTL epitopes with or without intramuscular (i.m.) injections of poly-ICLC.
|
78 |
20549206
|
Both IFN-alphaR(-/-) and IFN-gamma(-/-) hosts failed to up-regulate the CXCL10 mRNA and recruit Tc1 cells to the tumor site, indicating non-redundant roles of type-1 and type-2 IFNs in the effects of poly-ICLC-assisted vaccines.

Myxoma virus induces type I interferon production in murine plasmacytoid dendritic cells via a TLR9/MyD88-, IRF5/IRF7-, and IFNAR-dependent pathway.
|
88 |
21835795
|
Using pDCs derived from genetic knockout mice, we show that the myxoma virus-induced innate immune response requires the endosomal DNA sensor TLR9 and its adaptor MyD88, transcription factors IRF5 and IRF7, and the type I IFN positive-feedback loop mediated by IFNAR1.
|
89 |

It is independent of the cytoplasmic RNA sensing pathway mediated by the mitochondrial adaptor molecule MAVS, the TLR3 adaptor TRIF, or the transcription factor IRF3.
|
90 |

NSs induces a shut-off of host transcription including interferon (IFN)-beta mRNA and promotes degradation of double-stranded RNA-dependent protein kinase (PKR) at the post-translational level.
|
97 |
22083261
|
IFN-beta is transcriptionally upregulated by interferon regulatory factor 3 (IRF-3), NF-kB and activator protein-1 (AP-1), and the binding of IFN-beta to IFN-alpha/beta receptor (IFNAR) stimulates the transcription of IFN-alpha genes or other interferon stimulated genes (ISGs), which induces host antiviral activities, whereas host transcription suppression including IFN-beta gene by NSs prevents the gene upregulations of those ISGs in response to viral replication although IRF-3, NF-kB and activator protein-1 (AP-1) can be activated by RVFV7.

SCFV gene expression was over 100 fold-higher on days 1-3 post-infection in type I IFN receptor knockout mice (IFNAR(-/-)) compared to wild-type (wt) mice indicating a profound IFN-mediated suppression of SCFV gene expression in the wt animals.
|
99 |
22226862
|
IFNAR(-/-) mice produced nearly equivalent levels of WNV-specific serum IgG and WNV-specific CD4(+) T cell responses compared to wt mice.
|
100 |
22226862
|
However, significantly higher numbers of WNV-specific CD8(+) T cells were produced by IFNAR(-/-) mice and a significantly greater percentage of these T cells from IFNAR(-/-) mice produced only IFN-γ following antigen-specific re-stimulation.
|
101 |
22226862
|
This altered cytokine expression was not associated with increased antigen load suggesting the loss of type I IFN receptor signaling was responsible for the altered quality of the CD8(+) effector T cell response.
|
102 |
22226862
|
Together, these results indicate that although type I IFN is not essential for the intrinsic adjuvanting of RepliVAX WN, it plays a role in shaping the cytokine secretion profiles of CD8(+) effector T cells elicited by this SCFV.

Deletion of the Ifnar gene in subsets of myeloid cells resulted in uncontrolled WNV replication, vasoactive cytokine production, sepsis, organ damage, and death that were remarkably similar to infection of Ifnar-/- mice completely lacking type I IFN signaling.

In Mavs-/-×Ifnar-/- myeloid cells and mice lacking both Ifnar and the RIG-I-like receptor adaptor gene Mavs, cytokine production was muted despite high levels of WNV infection.

Vaccination with irradiated granulocyte macrophage colony-stimulating factor (GM-CSF)-transduced autologous tumor cells (GVAX) has been shown to induce therapeutic antitumor immunity.
|
129 |
24830413
|
Indeed, mouse experiments demonstrated that the effective induction of GM-CSF-induced antitumor immunity observed in immunocompetent mice treated with LLC/SeV/GM cells was significantly attenuated when pDC-depleted or IFNα receptor knockout (IFNAR(-/-)) mice were used.
|
130 |
24830413
|
Mechanistically, mice treated with the combined vaccination displayed increased expression levels of CD86, CD9, and Siglec-H, which correlate with an antitumor phenotype, in pDCs, but decreased the ratio of CD4(+)CD25(+)FoxP3(+) regulatory T cells in TDLNs.
|
131 |

|
Collectively, these findings indicate that the additional use of imiquimod to activate pDCs with type I IFN production, as a positive regulator of T-cell priming, could enhance the immunologic antitumor effects of GVAX therapy, shedding promising light on the understanding and treatment of GM-CSF-based cancer immunotherapy.

BTV-4 structural proteins VP2 (as two domains: VP2D1 and VP2D2), VP5 (lacking the first 100 amino acids: VP5Δ1-100) and full-length VP7, expressed in bacteria as soluble glutathione S-transferase (GST) fusion-proteins, were used to immunise Balb/c and α/β interferon receptor knock-out (IFNAR(-/-)) mice.

Our data indicate that SNPs near the butyrophilin genes (BTN3A3/BTN2A1) and cytokine receptors (IL10RB/IFNAR1) are associated with variations in IFNγ secretion and that multiple SNPs in the PVR gene, as well as SNPs located in the ADAR gene, exhibit significant associations with rubella virus-specific IL-6 secretion.

In this article, we report that C57BL/6 mice lacking the adapter protein MyD88, which mediates signaling by TLRs and IL-1 family members, showed enhanced immunity to H. polygyrus infection.
|
135 |
25114104
|
Alongside increased parasite expulsion, MyD88-deficient mice showed heightened IL-4 and IL-17A production from mesenteric lymph node CD4(+) cells.
|
136 |
25114104
|
In addition, MyD88(-/-) mice developed substantial numbers of intestinal granulomas around the site of infection, which were not seen in MyD88-sufficient C57BL/6 mice, nor when signaling through the adapter protein TRIF (TIR domain-containing adapter-inducing IFN-β adapter protein) was also ablated.
|
137 |
25114104
|
Mice deficient solely in TLR2, TLR4, TLR5, or TLR9 did not show enhanced parasite expulsion, suggesting that these TLRs signal redundantly to maintain H. polygyrus susceptibility in wild-type mice.
|
138 |
25114104
|
Like IL-1R1(-/-) and MyD88(-/-) mice, animals lacking signaling through the type 1 IFN receptor (i.e., IFNAR1(-/-)) also developed intestinal granulomas.
|
139 |
25114104
|
Hence, IL-1R1, MyD88, and type 1 IFN receptor signaling may provide pathways to impede granuloma formation in vivo, but additional MyD88-mediated signals are associated with inhibition of protective immunity in susceptible C57BL/6 mice.

In this study, we investigated how neutralizing the interferon (IFN) response in PBS-12SF cells, via shRNA-mediated knock-down of IFNAR1 mRNA expression, affects influenza virus production.

Transcription factors IRF3 (IFN regulatory factor 3) and IRF7, and the positive feedback loop mediated by IFNAR1 (IFN alpha/beta receptor 1), are required for the induction.

MVA infection of cDCs triggers phosphorylation of TBK1 (Tank-binding kinase 1) and IRF3, which is abolished in the absence of cGAS and STING.
|
144 |

|
Furthermore, intravenous delivery of MVA induces type I IFN in wild-type mice, but not in mice lacking STING or IRF3.
|
145 |

|
Treatment of cDCs with inhibitors of endosomal and lysosomal acidification or the lysosomal enzyme Cathepsin B attenuated MVA-induced type I IFN production, indicating that lysosomal enzymatic processing of virions is important for MVA sensing.
|

|
We present evidence that vaccinia virulence factors E3 and N1 inhibit the activation of IRF3 and the induction of IFNB gene in MVA-infected cDCs.
