12050378
|
Cotransfection of HA with IRF-3 and IRF-7 increased CD4 T-cell responses by 2- to 4-fold and CD8 T-cell responses by more than 10-fold.
|

12050378
|
Following intramuscular deliveries of DNA, both CD4 and CD8 T cells were biased towards type 1 immune responses and the production of gamma interferon.
|
4 |
12050378
|
The biases of the T-cell responses towards type 1 or type 2 were stronger for immunizations with IRF-3 as an adjuvant than for immunizations with IRF-7 as an adjuvant.
|

Effects of nonstructural proteins NS1 and NS2 of human respiratory syncytial virus on interferon regulatory factor 3, NF-kappaB, and proinflammatory cytokines.

15827150
|
It has been shown previously that HRSV nonstructural proteins 1 and 2 (NS1 and NS2) inhibit the induction of alpha/beta interferon (IFN-alpha/beta) in A549 cells and human macrophages.
|
30 |
15827150
|
Two principal transcription factors for the early IFN-beta and -alpha1 response are interferon regulatory factor 3 (IRF-3) and nuclear factor kappaB (NF-kappaB).
|
31 |
15827150
|
At early times postinfection, wild-type HRSV and the NS1/NS2 deletion mutants were very similar in the ability to activate IRF-3.
|
32 |
15827150
|
However, once NS1 and NS2 were expressed significantly, they acted cooperatively to suppress activation and nuclear translocation of IRF-3.
|
33 |
15827150
|
Since these viruses differed greatly in the induction of IFN-alpha/beta, NF-kappaB activation was evaluated in Vero cells, which lack the structural genes for IFN-alpha/beta and would preclude confounding effects of IFN-alpha/beta.
|
34 |
15827150
|
Since recombinant HRSVs from which the NS1 or NS2 genes have been deleted are being developed as vaccine candidates, we investigated whether the changes in activation of host transcription factors and increased IFN-alpha/beta production had an effect on the epithelial production of proinflammatory factors.
|
35 |
15827150
|
Viruses lacking NS1 and/or NS2 stimulated modestly lower production of RANTES (Regulated on Activation Normal T-cell Expressed and Secreted), interleukin 8, and tumor necrosis factor alpha compared to wild-type recombinant RSV, supporting their use as attenuated vaccine candidates.

Immediately upon entry, viruses activate interferon-regulatory factor 3 (IRF3), as well as nuclear factor kappaB (NF-kappaB), which transactivate a subset of ISGs, proinflammatory genes, as well as IFN genes.
|
61 |
15858025
|
Since infection during inhibition of protein expression by cycloheximide or inactivation of viral gene expression by UV treatment did not trigger IRF3 activation or ISG expression by RhCMV, we conclude that RhCMV virions contain a novel inhibitor of IFN-independent viral induction of ISG expression by IRF3.

In contrast, r-CR84G, r-CF170S and r-CDelta170 were defective for inhibition of IRF-3 activation and IFN production and r-CF170S and r-CDelta170 did not inhibit IFN signaling.

The VP35 protein of Zaire Ebola virus is an essential component of the viral RNA polymerase complex and also functions to antagonize the cellular type I interferon (IFN) response by blocking activation of the transcription factor IRF-3.

|
DNA-dependent activator of IFN regulatory factors (IRF; DAI, also known as ZBP1 or DLM-1) is a cytosolic DNA sensor that initiates IRF3 and NF-kappaB pathways leading to activation of type I IFNs (IFNalpha, IFNbeta) and other cytokines.
|
75 |
18941233
|
In this study, induction of NF-kappaB is shown to depend on the adaptor receptor-interacting protein kinase (RIP)1, acting via a RIP homotypic interaction motif (RHIM)-dependent interaction with DAI.
|
76 |
18941233
|
DAI binds to and colocalizes with endogenous RIP1 at characteristic cytoplasmic granules.
|
77 |
18941233
|
Suppression of RIP1 expression by RNAi abrogates NF-kappaB activation as well as IFNbeta induction by immunostimulatory DNA.
|
78 |
18941233
|
DAI also interacts with RIP3 and this interaction potentiates DAI-mediated activation of NF-kappaB, implicating RIP3 in regulating this RHIM-dependent pathway.
|
79 |
18941233
|
The role of DAI in activation of NF-kappaB in response to immunostimulatory DNA appears to be analogous to sensing of dsRNA by TLR3 in that both pathways involve RHIM-dependent signaling that is mediated via RIP1, reinforcing a central role for this adaptor in innate sensing of intracellular microbes.

|
Using an endotoxin free rHagB preparation, our results show that stimulation of murine bone marrow-derived DC with rHagB leads to upregulation of the costimulatory molecules CD86 and CD40, activation of p38 and ERK MAP kinases, transcription factors NF-kappaB, CREB and IRF-3 and the production of IL-6, TNF-alpha, IL-12p40 and to a lesser extent IL-10 and IFN-beta.
|
82 |
19540594
|
This activation process was absolutely dependent on TLR4 and CD14.
|
83 |
19540594
|
While upregulation of CD86 was independent of the adaptor molecule MyD88, CD40 upregulation and optimal cytokine (IL-6, TNF-alpha, IL-12p40, IL-10 and IFN-beta) production required both MyD88 and TRIF molecules.

The potency of cytosolic signaling induced by c-di-GMP is comparable to that induced by cytosolic delivery of DNA, and both nucleic acids induce a similar transcriptional profile, including triggering of type I interferons and coregulated genes via induction of TBK1, IRF3, nuclear factor kappaB, and MAP kinases.

Moreover, we identify Z-DNA binding protein 1 (ZBP1) as being essential for IRF3 activation and interferon beta expression triggered by HCMV, as well as being sufficient to enhance HCMV-stimulated beta interferon transcription and secretion.
|
86 |
19846511
|
ZBP1 transcription was also found to be induced following exposure to HCMV in a JAK/STAT-dependent manner, thus perhaps also contributing to a positive feedback signal.
|
87 |
19846511
|
ZBP1 was recently identified as a cytosolic pattern recognition receptor of double-stranded DNA, and thus, we propose a model for HCMV-mediated IRF3 activation that involves HCMV-associated DNA as the principal innate immune-activating pathogen-associated molecular pattern.

The enhanced IFN-inducing capacity of the C(ko) virus correlated with an enhanced activation of IFN regulatory factor 3 (IRF-3), NF-kappaB, and ATF-2 in C(ko)-infected compared to V(ko) or parental virus-infected cells.
|
92 |
19846517
|
Furthermore, protein kinase PKR and mitochondrial adapter IPS-1 were required for maximal C(ko)-mediated IFN-beta induction, which correlated with the PKR-mediated enhancement of mitogen-activated protein kinase and NF-kappaB activation.

Our results reveal multiple consequences of C protein expression and document an important function for PKR as an enhancer of IFN-beta induction during measles virus infection.

Since natural lipid A from bacterial LPS depends on membrane-bound (mCD14) or soluble CD14 for its TLR4 ligand activity, we investigated the involvement of both forms of CD14 in the responses elicited by CRX-527.
|
95 |
20039305
|
First, we found that CRX-527 induces NF-kappaB and interferon regulatory factor-3 (IRF-3) activation in human embryonic kidney cells transfected with TLR4 and MD-2 genes alone, whereas the responses to LPS require either co-transfection of the gene encoding mCD14 or addition of soluble CD14.
|
96 |
20039305
|
We then observed that monocyte-derived DC, which are devoid of mCD14 respond to CRX-527 but not to LPS in serum-free medium.
|
97 |
20039305
|
Finally, we demonstrated that splenocytes from CD14-deficient mice produce cytokines in response to CRX-527 but not to LPS.

Here we report an approach to enhance the immunogenicity of DNA vaccines involving the use of transcription factors of the Interferon regulatory factor (IRF) family, specifically IRF-1, IRF-3, and IRF-7 using the tat gene as model antigen.
|

20432465
|
In vivo administration of plasmid DNA encoding IRF-1, or a mutated version of IRF-1 deleted of the DNA-binding domain, enhanced Tat-specific immune responses and shifted them towards a predominant T helper 1-type immune response with increased IFN-gamma production and cytotoxic T lymphocytes responses.

Conversely, the use of IRF-3 or IRF-7 did not affect the tat-induced responses.

The overexpression of the wild-type V protein suppressed melanoma differentiation-associated gene 5 (MDA5)-induced IFN-β promoter activity, while this was not seen in A549 cells expressing CD150 transfected with the V protein of the vaccine strain.
|

The V proteins of the wild-type and vaccine strain did not affect retinoic acid-inducible gene 1 (RIG-I)- or toll-IL-1R homology domain-containing adaptor molecule 1 (TICAM-1)-induced IFN-β promoter activation.
|
109 |
21071089
|
The mutation introduced into the wild-type V protein (C272R) was unable to suppress MDA5-induced IRF-3 nuclear translocation and IFN-β promoter activation as seen in the V proteins of the vaccine strain, whereas the mutation introduced in the vaccine strain V protein (R272C) was able to inhibit MDA5-induced IRF-3 and IFN-β promoter activation.
|

Activation of RIG-I leads to type I interferon (IFN) and inflammatory cytokine production through interferon promoter stimulator 1 (IPS-1)-mediated activation of interferon regulatory factor 3 (IRF3) and NF-κB signaling.
|
117 |

|
The resultant eRNA vectors potently induced type 1 IFN production in cell culture through RIG-I activation and combined high-level HA antigen expression with RNA-mediated type I IFN activation in a single plasmid vector.

Two RNA helicases, retinoic acid inducible gene-I (RIG-I) and melanoma differentiation-associated gene 5 (MDA5), are recently identified as cytoplasmic PPRs for virus infection.
|
119 |
21113677
|
Here, in this study the involvement of RIG-I and MDA5 in DENV-induced IFN-β response A549 cells were investigated.
|
120 |
21113677
|
DENV infection readily up-regulated RIG-I expression, activated IRF-3 and RIG-I mRNA transcription, and induced the production of IFN-β in A549 cells in a strain- and serotype-independent manner.
|
121 |
21113677
|
Our results demonstrated that both RIG-I and MDA5 were induced but neither of the two was essential for DENV induced IFN IFN-β response in A549 cells.
|
122 |

|
Consequently, the cytosolic DNA sensor, DNA-dependent activator of interferon (IFN) regulatory factors (DAI), was used as a genetic adjuvant.
|
123 |

|
In vivo electroporation (EP) of mice with a DAI-encoding plasmid (pDAI) promoted transcription of genes encoding type I IFNs, proinflammatory cytokines, and costimulatory molecules.
|
124 |
21157438
|
Moreover, codelivery of pDAI effectively promoted CTL and CD4(+) Th1 responses to the TAA survivin.
|
125 |
21157438
|
The DAI-enhanced CTL induction required nuclear factor κB (NF-κB) activation and type I IFN signaling, but did not involve the IFN regulatory factor 3 (IRF3).
|
126 |
21157438
|
Codelivery of pDAI also increased CTL responses to the melanoma-associated antigen tyrosinase-related protein-2 (TRP2), enhanced tumor rejection and conferred long-term protection against B16 melanoma challenge.

Regulation of influenza A virus induced CXCL-10 gene expression requires PI3K/Akt pathway and IRF3 transcription factor.
|
128 |
21497908
|
To understand the regulation of CXCL-10, we investigated the role of PI3K/AKT pathway in regulating virus induced CXCL-10 production.
|
129 |
21497908
|
Previously we have shown that wild type (WT) influenza A virus infection activates PI3K/AKT pathway, whereas PR8-SH3-mf-1 mutant virus is unable to activate this pathway.
|
130 |
21497908
|
Our data suggested that PI3K/AKT pathway contributes to influenza A virus induced CXCL-10 production.
|
131 |
21497908
|
This process is involved in binding of IRF3 to the ISRE binding site in CXCL-10 promoter region.

Myxoma virus induces type I interferon production in murine plasmacytoid dendritic cells via a TLR9/MyD88-, IRF5/IRF7-, and IFNAR-dependent pathway.
|
138 |
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.
|
139 |
21835795
|
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.
|
140 |
21835795
|
Using pharmacological inhibitors, we demonstrate that myxoma virus-induced type I IFN and IL-12p70 production in murine pDCs is also dependent on phosphatidylinositol 3-kinase (PI3K) and Akt.
|
141 |

|
Cytosolic detection of pathogen-derived DNA is one major mechanism of inducing IFN production, and this process requires signalling through TANK binding kinase 1 (TBK1) and its downstream transcription factor, IFN-regulatory factor 3 (IRF3).
|
142 |
21947006
|
In addition, a transmembrane protein called STING (stimulator of IFN genes; also known as MITA, ERIS, MPYS and TMEM173) functions as an essential signalling adaptor, linking the cytosolic detection of DNA to the TBK1-IRF3 signalling axis.
|

Alternatively, RABV uses its phosphoprotein to interfere with IRF-3 phosphorylation and STAT1 signaling.

NYCBHΔE3L induced phosphorylation of PKR and eIF2α as well as p38, SAPK/JNK, and IRF3 which can lead to induction of proinflammatory gene transcription.

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.
|
146 |
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.

Adenosine deaminase acting on RNA 1 (ADAR1) suppresses the induction of interferon by measles virus.
|
148 |
22278222
|
ADAR1, the interferon (IFN)-inducible adenosine deaminase acting on RNA, catalyzes the C-6 deamination of adenosine (A) to produce inosine (I) in RNA substrates with a double-stranded character.
|
149 |
22278222
|
Because double-stranded RNA is a known inducer of IFN, we tested the role of ADAR1 in IFN induction following virus infection.
|
150 |
22278222
|
HeLa cells made stably deficient in ADAR1 (ADAR1(kd)) were compared to vector control (CON(kd)) and protein kinase PKR-deficient (PKR(kd)) cells for IFN-β induction following infection with either parental (wild-type [WT]) recombinant Moraten vaccine strain measles virus (MV) or isogenic knockout mutants deficient for either V (V(ko)) or C (C(ko)) protein expression.
|
151 |
22278222
|
We observed potent IFN-β transcript induction in ADAR1(kd) cells by all three viruses; in contrast, in ADAR1-sufficient CON(kd) cells, only the C(ko) mutant virus was an effective inducer and the IFN-β RNA induction was amplified by PKR.
|
152 |
22278222
|
The enhanced IFN-β transcript-inducing capacity of the WT and V(ko) viruses seen in ADAR1-deficient cells correlated with the enhanced activation of PKR, IFN regulatory factor IRF3, and activator of transcription ATF2, reaching levels similar to those seen in C(ko) virus-infected cells.
|
153 |
22278222
|
These results suggest that ADAR1 functions as an important suppressor of MV-mediated responses, including the activation of PKR and IRF3 and the induction of IFN-β RNA.
|
154 |
22278222
|
Our findings further implicate a balanced interplay between PKR and ADAR1 in modulating IFN-β protein production following virus infection.

More importantly, PDLC strengthened the TLR3 signaling in BMDCs by enhancing the interaction of PIC with TLR3 and augmenting downstream IRF-3 phosphorylation, as well as elevating IRF-3/IRF-7 mRNA transcription.
|
164 |
23165138
|
The ASFV A276R gene from MGF360 inhibited the induction of IFN-β via both the TLR3 and the cytosolic pathways, targeting IRF3, but not IRF7 or NF-κB.
|
165 |
23251783
|
We show that DNA-PK acts as a pattern recognition receptor, binding cytoplasmic DNA and triggering the transcription of type I interferon (IFN), cytokine and chemokine genes in a manner dependent on IFN regulatory factor 3 (IRF-3), TANK-binding kinase 1 (TBK1) and stimulator of interferon genes (STING).
|
166 |
23884215
|
Mice lacking IRF3, IFN-α receptor, IL-1β/IL-18, TLR9 or MyD88 showed similar CTL responses to wild-type mice, arguing that none of these molecules were required for the immunogenicity of DNA vaccines.

Toll-like receptor 3-mediated necrosis via TRIF, RIP3, and MLKL.
|
168 |
24019532
|
Toll-like receptor (TLR) signaling is triggered by pathogen-associated molecular patterns that mediate well established cytokine-driven pathways, activating NF-κB together with IRF3/IRF7.
|
169 |
24019532
|
In addition, TLR3 drives caspase 8-regulated programmed cell death pathways reminiscent of TNF family death receptor signaling.
|
170 |
24019532
|
We find that inhibition or elimination of caspase 8 during stimulation of TLR2, TLR3, TLR4, TLR5, or TLR9 results in receptor interacting protein (RIP) 3 kinase-dependent programmed necrosis that occurs through either TIR domain-containing adapter-inducing interferon-β (TRIF) or MyD88 signal transduction.
|
171 |
24019532
|
TLR3 or TLR4 directly activates programmed necrosis through a RIP homotypic interaction motif-dependent association of TRIF with RIP3 kinase (also called RIPK3).
|
172 |
24019532
|
In fibroblasts, this pathway proceeds independent of RIP1 or its kinase activity, but it remains dependent on mixed lineage kinase domain-like protein (MLKL) downstream of RIP3 kinase.
|
173 |
24019532
|
Here, we describe two small molecule RIP3 kinase inhibitors and employ them to demonstrate the common requirement for RIP3 kinase in programmed necrosis induced by RIP1-RIP3, DAI-RIP3, and TRIF-RIP3 complexes.
|
174 |
24019532
|
Cell fate decisions following TLR signaling parallel death receptor signaling and rely on caspase 8 to suppress RIP3-dependent programmed necrosis whether initiated directly by a TRIF-RIP3-MLKL pathway or indirectly via TNF activation and the RIP1-RIP3-MLKL necroptosis pathway.

We investigated the roles of IFN regulatory factor (IRF)-3 and IRF-7 in innate antiviral immunity against dengue virus (DENV).
|
177 |
24043884
|
IFN-α/β was induced similarly in wild-type and Irf-3(-/-) mice post-DENV infection, whereas in the Irf-7(-/-) and Irf-3(-/-)7(-/-) mice, significantly low levels of IFN-α/β expression was observed within 24 hpi.
|
178 |
24043884
|
IFN-stimulated gene induction was also delayed in Irf-3(-/-)7(-/-) mice relative to wild-type and single-deficient mice.
|
179 |
24043884
|
In particular, Cxcl10 and Ifnα2 were rapidly induced independently of both IRF-3 and IRF-7 in the Irf-3(-/-)7(-/-) mice with DENV infection.
|
180 |
24043884
|
Higher levels of serum IFN-γ, IL-6, CXCL10, IL-8, IL-12 p70, and TNF were also observed in Irf-3(-/-)7(-/-) mice 24 hpi, at which time point viral titers peaked and started to be cleared.
|
181 |
24043884

Ab-mediated blockade experiments revealed that IFN-γ, CXCL10, and CXCR3 function to restrict DENV replication in Irf-3(-/-)7(-/-) mice.
|
182 |
24043884
|
Additionally, the IFN-stimulated genes Cxcl10, Ifit1, Ifit3, and Mx2 can be induced via an IRF-3- and IRF-7-independent pathway that does not involve IFN-γ signaling for protection against DENV.
|
183 |
24043884
|
Collectively, these results demonstrate that IRF-3 and IRF-7 are redundant, albeit IRF-7 plays a more important role than IRF-3 in inducing the initial IFN-α/β response; only the combined actions of IRF-3 and IRF-7 are necessary for efficient control of early DENV infection; and the late, IRF-3- and IRF-7-independent pathway contributes to anti-DENV immunity.

Collectively, these results demonstrate that IRF-3 and IRF-7 are redundant, albeit IRF-7 plays a more important role than IRF-3 in inducing the initial IFN-α/β response; only the combined actions of IRF-3 and IRF-7 are necessary for efficient control of early DENV infection; and the late, IRF-3- and IRF-7-independent pathway contributes to anti-DENV immunity.

|
We investigated the roles of IFN regulatory factor (IRF)-3 and IRF-7 in innate antiviral immunity against dengue virus (DENV).
|
231 |
24043884
|
IFN-α/β was induced similarly in wild-type and Irf-3(-/-) mice post-DENV infection, whereas in the Irf-7(-/-) and Irf-3(-/-)7(-/-) mice, significantly low levels of IFN-α/β expression was observed within 24 hpi.
|
232 |
24043884
|
IFN-stimulated gene induction was also delayed in Irf-3(-/-)7(-/-) mice relative to wild-type and single-deficient mice.
|
233 |
24043884
|
In particular, Cxcl10 and Ifnα2 were rapidly induced independently of both IRF-3 and IRF-7 in the Irf-3(-/-)7(-/-) mice with DENV infection.
|
234 |
24043884
|
Higher levels of serum IFN-γ, IL-6, CXCL10, IL-8, IL-12 p70, and TNF were also observed in Irf-3(-/-)7(-/-) mice 24 hpi, at which time point viral titers peaked and started to be cleared.
|
235 |
24043884
|
Ab-mediated blockade experiments revealed that IFN-γ, CXCL10, and CXCR3 function to restrict DENV replication in Irf-3(-/-)7(-/-) mice.
|
236 |
24043884
|
Additionally, the IFN-stimulated genes Cxcl10, Ifit1, Ifit3, and Mx2 can be induced via an IRF-3- and IRF-7-independent pathway that does not involve IFN-γ signaling for protection against DENV.

RAE1 ligands for the NKG2D receptor are regulated by STING-dependent DNA sensor pathways in lymphoma.
|
241 |

It is thought that c-di-GMP is recognized by ATP dependent RNA helicase (DDX41) in the cytosol, forms a complex with the Stimulator of interferon genes protein (STING), triggers a signal via the tank binding kinase 1-interferon regulatory factor 3 (TBK1-IRF3) pathway and induces the production of type I interferons.
|
243 |

C-di-GMP liposomes also showed significantly higher levels of expression of CD80, CD86 and MHC class I.

Helicase proteins DHX29 and RIG-I cosense cytosolic nucleic acids in the human airway system.
|
245 |
24821782
|
Knocking down DHX29 by siRNA attenuated the ability of cells to mount type I IFN and IL-6 in response to cytosolic nucleic acids and various viruses by blocking the activation of interferon regulatory factor 3 and NF-κB-p65.
|
246 |
24821782
|
The cytosolic nucleic acid sensing by DHX29 in human epithelial cells and fibroblasts is independent of stimulator of interferon genes but is dependent on retinoic acid-inducible gene 1 (RIG-I) and mitochondrial antiviral signaling protein (MAVS).
|
247 |
24821782
|
DHX29 binds directly to nucleic acids and interacts with RIG-I and MAVS through its helicase 1 domain, activating the RIG-I-MAVS-dependent cytosolic nucleic acid response.
|
248 |
24821782
|
These results suggest that DHX29 is a cytosolic nucleic acid cosensor that triggers RIG-I/MAVS-dependent signaling pathways.

|
252 |
25211222
|
TRIF related adaptor molecule (TRAM) plays a vital role in TLR4 signaling by recruiting TRIF to TLR4, followed by endosomal trafficking of the complex and initiation of IRF3 dependent type I interferon production as well as NF-κB dependent pro-inflammatory cytokine production.
|
253 |
25211222
|
Towards understanding the molecular mechanisms that regulate TLR7 functionality, we found that TRAM(-/-) murine macrophages exhibited a transcriptional and translational impairment in TLR7 mediated RANTES, but not TNFα, production.
|
254 |
25211222
|
Suppression of TRAM expression in human macrophages also resulted in an impairment in TLR7 mediated CCL5 and IFN-β, but not TNFα, gene induction.
|
255 |
25211222
|
Additionally, TRAM-G2A dose-dependently inhibited TLR7 mediated activation of CCL5, IFNβ and IFNα reporter genes.

|
TLR7-mediated phosphorylation and nuclear translocation of IRF3 was impaired in TRAM(-/-) cells.

Finally, co-immunoprecipitation studies indicated that TRAM physically interacts with MyD88 upon TLR7 stimulation, but not under basal conditions.
|
258 |
25211222
|
Our results clearly demonstrate that TRAM plays a, hitherto unappreciated, role in TLR7 signaling through a novel signaling axis containing, but not limited to, MyD88, TRAM and IRF3 towards the activation of anti-viral immunity.

DEAD-box RNA helicase DDX3X inhibits DENV replication via regulating type one interferon pathway.
|
276 |
25437271
|
The interferon (IFN)-β transcription level decreased during the early stage of DENV infection in DDX3X-silenced cells compared with that in the controls.
|
277 |
25437271
|
DDX3X could stimulate IFN-β transcription through the IRF3 and the NFκB branches in DENV-infected cells.
|
278 |
25437271

Our data imply that DDX3X, a member of DEAD-box RNA helicase, is necessary for IFN production and could inhibit DENV replication.

The results showed that the mRNA and protein levels of TLR2, TLR4 and TLR7 were upregulated in response to CSFV infection, but TLR3 remained unchanged, and was downregulated after infection with the C strain and the Shimen virus, respectively.
|
281 |
25805409

In this study, we report that protein kinase CK2 serves as a key component controlling TBK1 and IRF3 activation in IFN-inducing TLR, RIG-I-like receptors, and cGAS/STING signaling pathways.
|
284 |
25810395

Moreover, PP2A was identified as one of the intermediate phosphatases responsible for CK2-regulated IFN response, suggesting that CK2 may regulate TBK1 and IRF3 activation indirectly.

Taken together, our results identify CK2 as a novel regulator of TBK1 and IRF3 and suggest that targeting CK2 by small molecular inhibitor may be a viable approach to prevent and treat viral infections.

Here, we show that anticancer vaccine adjuvant, PolyIC (primarily sensed by MDA5) and the oncolytic virus, Newcastle disease virus (NDV) (sensed by RIG-I), induce anticancer activity.
|
303 |
25950488
|
PolyIC transfection and NDV infection upregulate pro-apoptotic gene TRAIL and downregulate the anti-apoptotic genes BCL2, BIRC3 and PRKCE.
|
304 |

Furthermore, stable knockdown of IPS-1, IRF3 or IRF7 in IFN-non-responsive cancer cells show reduced anticancer activity by suppressing apoptosis via TRAIL and anti-apoptotic genes.

Although prothymosin-alpha contributes to toll-like receptor (TLR4)-mediated immnunopotentiation against viral infection, the beneficial effects of prothymosin-alpha-TLR4 signaling in protecting against ischemia remain to be elucidated.
|
313 |
26364961
|
All these preventive effects of prothymosin-alpha preconditioning were abolished in TLR4 knock-out mice and by pre-treatments with anti-TLR4 antibodies or minocycline, a microglial inhibitor.
|
314 |
26364961
|
Prothymosin-alpha preconditioning inhibited the retinal ischemia-induced up-regulation of TLR4-related injury genes, and increased expression of TLR4-related protective genes.
|
315 |
26364961
|
Furthermore, the prothymosin-alpha preconditioning-induced prevention of retinal ischemic damage was abolished in TIR-domain-containing adapter-inducing interferon-β knock-out mice, but not in myeloid differentiation primary response gene 88 knock-out mice.
|
316 |
26364961
|
We propose the following mechanism for prothymosin-alpha (ProTα) preconditioning-induced retinal prevention against ischemia: ProTα preconditioning-induced prevention of retinal ischemic damage is mediated by selective activation of the TIR-domain-containing adapter-inducing interferon-β (TRIF)- interferon regulatory factor 3 (IRF3) pathway downstream of toll-like receptor 4 (TLR4) in microglia, resulting in up-regulation of TRIF-IRF3-dependent protective genes and down-regulation of myeloid differentiation primary response gene 88 (MyD88)-Nuclear factor (NF)κB-dependent injury genes.
