By using 70Z/3-derived pre-B-cell lines either lacking or expressing human CD14 (the LPS receptor), it was observed that expression of human CD14 imparted responsiveness to LPS but not to OspA or spirochetal lipopeptides (assessed by induction of NF-kappa B and expression of surface immunoglobulin M).

OspA also rapidly up-regulated endothelial cell production of several proteins whose transcription is dependent on NF-kappa B: the cytokine IL-6; the chemokine IL-8; and the adhesion molecules E-selectin, VCAM-1, and ICAM-1.

Recent findings in B lymphocytes have clearly illustrated that these external inputs affect the magnitude and duration of the intracellular calcium response, which in turn contributes to differential triggering of the transcriptional regulators NF kappa B, JNK, NFAT, and ERK.

|
The regulation of calcium responses involves a network of tyrosine kinases (e.g. lyn, syk), tyrosine or lipid phosphatases (CD45, SHP-1, SHIP), and accessory molecules (CD21/CD19, CD22, FcR gamma 2b).

Because polysaccharides of the bacterial cell wall stimulate TNF-alpha production by monocyte-macrophages and TNF-alpha was shown to stimulate HIV replication directly on activation of NF-kappa b after binding the long terminal repeat (LTR) sequences of HIV, we measured TNF-alpha production and observed a significant increase in both groups of vaccines.

The expression of intercellular adhesion molecule 1 (ICAM-1) by endothelial cells is important for the regulation of adhesion and transendothelial migration of a variety of leukocytes that express the integrins lymphocyte function-associated antigen 1 (LFA-1) and/or Mac-1.
|

The vasoactive intestinal peptide (VIP) and the structurally related neuropeptide pituitary adenylate cyclase-activating polypeptide (PACAP) act as "macrophage-deactivating factors".
|
21 |
10542221

B lymphocyte stimulator (BLyS) is a newly identified monocyte-specific TNF family cytokine.
|
35 |
11015437
|
BLyS acts on primary splenic B cells autonomously, and directly cooperates with CD40 ligand (CD40L) in B cell activation in vitro by protecting replicating B cells from apoptosis.
|
36 |
11015437
|
Attenuation of apoptosis by BLyS correlates with changes in the ratios between Bcl-2 family proteins in favor of cell survival, predominantly by reducing the proapoptotic Bak and increasing its prosurvival partners, Bcl-2 and Bcl-xL.
|
37 |
11015437
|
In either resting or CD40L-activated B cells, the NF-kappaB transcription factors RelB and p50 are specifically activated, suggesting that they may mediate BLyS signals for B cell survival.
|
38 |
11015437
|
The ability of BLyS to increase B cell survival indiscriminately, at either a resting or activated state, and to cooperate with CD40L, further suggests that attenuation of apoptosis underlies BLyS enhancement of polyclonal autoimmunity as well as the physiologic humoral immune response.

The growth rates of both vaccines in murine macrophages were the same, however, Onco-BCG induced stronger and longer-lasting secretion of TNF-alpha, IL-6 and nitric oxide.
|
40 |
11029527
|
Onco-vaccine was also more potent in inducing NF-kappaB p65/p50 DNA-binding activity whilst in ID-BCG-infected cells the activity was transient and then gradually replaced by the transcriptionally inactive homodimer p50/p50.

45 |
11441107
|
Toll-like receptor 2 (TLR2) and TLR4 play important roles in innate immune responses to various microbial agents.
|
46 |
11441107
|
We have previously shown that human dermal endothelial cells (HMEC) express TLR4, but very little TLR2, and respond to LPS, but not to Mycobacterium tuberculosis 19-kDa lipoprotein, unless transfected with TLR2.
|
47 |
11441107
|
We further characterized the signaling pathway in response to STF, OspA-L, and PSM in TLR2-transfected HMEC.
|

|
The TLR2 signaling pathway for NF-kappaB trans-activation shares the IL-1R signaling molecules.
|
49 |
11441107
|
Dominant negative constructs of TLR2 or TLR6 inhibit the responses of STF and OspA-L as well as PSM in TLR2-transfected HMEC, supporting the concept of functional cooperation between TLR2 and TLR6 for all these TLR2 ligands.
|
50 |
11441107
|
Moreover, we show that Toll-interacting protein (Tollip) coimmunoprecipitates with TLR2 and TLR4 using HEK 293 cells, and overexpression of Tollip inhibits NF-kappaB activation in response to TLR2 and TLR4 signaling.
|
51 |
11441107
|
Collectively, these findings suggest that there is functional interaction between TLR2 and TLR6 in the cellular response to STF and OspA-L in addition to S. epidermidis (PSM) Ags, and that engagement of TLR2 triggers a signaling cascade, which shares the IL-1R signaling molecules, similar to the TLR4-LPS signaling cascade.
|
52 |

|
Our data also suggest that Tollip may be an important constituent of both the TLR2 and TLR4 signaling pathways.

|
Here we demonstrate that activation of the NF-kappaB pathway by the HTLV-1 Tax protein leads to transcriptional inactivation of c-Myb.

|
This conclusion was supported by the fact that Tax mutants unable to stimulate the NF-kappaB pathway could not inhibit c-Myb transactivating functions.
|
65 |
11585920
|
In addition, inhibition of Tax-mediated NF-kappaB activation by coexpression of IkappaBalpha restored c-Myb transcription, and Tax was unable to block c-Myb transcription in a NEMO knockout cell line.
|
66 |
11585920

This ability is dependent on MyD88 and Toll-like receptor (TLR)2 expression, as demonstrated by a lack of a response by B cells from MyD88 or TLR2 knockout mice to the porins.
|
93 |
11823477

Using previously described TLR2-dependent reporter constructs, these results were confirmed and were shown to be due to induction of NF-kappaB nuclear translocation.

|
The recognition of CpG motifs requires Toll-like receptor (TLR) 9, which triggers alterations in cellular redox balance and the induction of cell signaling pathways including the mitogen activated protein kinases (MAPKs) and NF kappa B.
|
95 |
11861616
|
Cells that express TLR-9, which include plasmacytoid dendritic cells (PDCs) and B cells, produce Th1-like proinflammatory cytokines, interferons, and chemokines.

Among the proinflammatory cytokines and their mRNAs measured (IL-6, IL-1 beta, IL-8, and tumor necrosis factor alpha), IL-8 showed the greatest change following D2V infection.
|
97 |
11991987
|
Nuclear factor kappa B (NF-kappa B) and nuclear factor IL-6 (NFIL-6) are primary mediators of IL-8 expression.
|
98 |
11991987
|
We studied the transcriptional regulation of IL-8 in the ECV304 and 293T cell lines and found that the induction of IL-8 gene expression involved the activation of NF-kappa B (P = 0.001) and, to a lesser extent, the activation of NFIL-6 in ECV304 cells only.
|
99 |
11991987
|
IL-8 produced by infected monocytes and also IL-8 that may be produced by endothelial or other epithelial cells is associated with the hyperacetylation of histones bound to the IL-8 promoter in addition to the activation of transcription by NF-kappa B.

The role of NF-kappaB in enhancement of TNF-alpha production was confirmed in experiments in which MG132, an inhibitor of NF-kappaB activation, reversed the effect of AdAMP.
|
109 |
12203103
|
AdAMP-induced augmentation of TNF-alpha production by B78/TNF cells was accompanied by morphological changes in the treated cells and a decrease in their adherence to fibrinogen and collagen IV.

We detected no activation of heat shock protein (HSP) 27, 60, 84 and 86, osmotic stress protein 94 (Osp 94), IL-12, extracellular signal-regulated protein kinase 1 (ERK1), p38 mitogen activated protein (MAP)-kinase (p38), c-Jun NH2-terminal kinase (JNK), signal transducer and activator of transcription 1 (STAT1), CD14 and caspase genes.

In experiments designed to get insights into the interactions between PTX and circulating immune cells, we first observed that addition of PTX to adult whole blood induced the release of IL-12 and TNF-alpha as well as maturation of myeloid dendritic cells (DC).
|
114 |
12385032
|
Secondly, studies on DC generated in vitro by culturing monocytes with IL-4 and GM-CSF showed that PTX directly stimulates MHC class II and costimulatory molecules up-regulation, cytokine synthesis and NF-kappa B activation.

CD28, TNF receptor, and IL-12 are critical for CD4-independent cross-priming of therapeutic antitumor CD8+ T cells.
|
116 |
12391201
|
Previously, we have shown that priming of therapeutic CD8(+) T cells in tumor vaccine-draining lymph nodes of mice vaccinated with GM-CSF secreting B16BL6 melanoma cells occurs independent of CD4 T cell help.
|
117 |
12391201
|
In this study, we examined the contribution of the major costimulatory molecules, CD40 ligand (CD40L), CD80, and CD86, in the priming of CD8(+) T cells.
|
118 |
12391201
|
Priming of therapeutic CD8(+) T cells by a GM-CSF-transduced tumor vaccine did not require CD40 and CD40L interactions, as therapeutic T cells could be generated from mice injected with anti-CD40L Ab and from CD40L knockout mice.
|
119 |
12391201
|
However, costimulation via either CD80 or CD86 was required, as therapeutic T cells could be generated from mice injected with either anti-CD80 or anti-CD86 Ab alone, but administration of both Abs completely inhibited the priming of therapeutic T cells.

Blocking experiments also identified that priming of therapeutic T cells in MHC class II-deficient mice required TNFR and IL-12 signaling, but signaling through CD40, lymphotoxin-betaR, or receptor activator of NF-kappaB was not essential.
|
121 |
12391201
|
Thus, cross-priming of therapeutic CD8(+) T cells by a tumor vaccine transduced with GM-CSF requires TNFR, IL-12, and CD28 signaling.

The mutant was found to be severely defective in inducing leukocyte signaling, as shown by failure to (i) trigger caspase 3-mediated CD8(+)-T-cell apoptosis, (ii) activate nuclear translocation of NF-kappaB in Jurkat T cells, (iii) induce a potent anti-B-subunit response in mice, or (iv) serve as a mucosal adjuvant.

Coexpression of 4-1BBL in these E7-expressing DCs increased effector and memory CTL responses when they were used for immunization. 4-1BBL expression up-regulated CD80 and CD86 second signaling molecules in DCs.
|
128 |
12626542
|
We also report an additive effect of 4-1BBL and receptor activator of NF-kappa B/receptor activator of NF-kappa B ligand coexpression in E7-transduced DC immunogens on E7-directed effector and memory CTL responses and on MHC class II and CD80/86 expression in DCs.

Peripheral blood monocytes were differentiated into immature DCs with interleukin-4 (IL-4) and granulocyte-macrophage colony-stimulating factor, and pulsed with an immunogenic tetanus toxoid peptide.
|
130 |
12641655
|
However, stimulation with antigen-pulsed DCs overexpressing IotakappaBetaalpha, the endogenous inhibitor of NF-kappaB, led to a significant reduction in T-cell proliferation, and decreased production of interferon-gamma, IL-4 and IL-10, whereas transforming growth factor-beta production was low throughout.

Similarly, in vitro experiments using a human fetal intestinal epithelial cell line (INT 407) demonstrated that, although significantly (P < 0.05) fewer S. enterica serovar Infantis than S. enterica serovar Typhimurium organisms invaded the monolayers, S. enterica serovar Infantis induced an NF-kappaB response and significantly (P < 0.05) raised interleukin 8 levels and transmigration of porcine PMN.

Among those signaling pathways, activation of NF-kappaB leads to up-regulation of IL-1beta, IL-8 and TNF-alpha, mucin MUC2 and Toll-like receptor 2 (TLR2), whereas activation of p38 MAP kinase mediates not only up-regulation of inflammatory mediators and mucin MUC5AC but also down-regulation of TLR2.
|
133 |
12686724
|
Interestingly, NTHi-induced activation of the PI3K-Akt pathway, however, leads to inhibition of p38 mitogen-activated protein (MAP) kinase.
|
134 |
12686724
|
Moreover, the TGF-beta-Smad signaling pathway cooperates with NF-kappaB to mediate up-regulation of mucin MUC2.
|
135 |
12686724
|
Finally, glucocorticoids synergistically enhance NTHi-induced TLR2 expression via specific up-regulation of the MAP kinase phosphatase-1 that, in turn, leads to inactivation of p38 MAP kinase, the negative regulator for TLR2 expression.

Enhanced effector and memory CTL responses generated by incorporation of receptor activator of NF-kappa B (RANK)/RANK ligand costimulatory molecules into dendritic cell immunogens expressing a human tumor-specific antigen.
|
141 |
14530334
|
In this study, we used adenoviral vectors to express a model tumor Ag (the E7 oncoprotein of human papillomavirus 16) with or without coexpression of receptor activator of NF-kappaB (RANK)/RANK ligand (RANKL) or CD40/CD40L costimulatory molecules, and used these transgenic DCs to immunize mice for the generation of E7-directed CD8(+) T cell responses.
|
142 |
14530334
|
We show that coexpression of RANK/RANKL, but not CD40/CD40L, in E7-expressing DCs augmented E7-specific IFN-gamma-secreting effector and memory T cells and E7-specific CTLs.
|
143 |
14530334
|
These responses were also augmented by coexpression of T cell costimulatory molecules (RANKL and CD40L) or DC costimulatory molecules (RANK and CD40) in the E7-expressing DC immunogens.
|
144 |
14530334
|
Augmentation of CTL responses correlated with up-regulation of CD80 and CD86 expression in DCs transduced with costimulatory molecules, suggesting a mechanism for enhanced T cell activation/survival.

14627128
|
Immature monocyte-derived dendritic cells (imMo-DCs) isolated from human peripheral blood monocytes stimulated with granulocyte-macrophage colony stimulating factor and interleukin-4 were exposed to maturation factors, i.e., lipopolysaccharide (LPS), tumor necrosis factor alpha (TNF-alpha) plus prostaglandin E2 (PGE2), and OK-432 for 2 days.
|
152 |
14627128
|
OK-432 increased expression of activation- and maturation-related molecules such as HLA-DR, CD80, CD83, and CD86 in imMo-DCs at levels similar to that of TNF-alpha plus PGE2, and higher than that of LPS.
|
153 |
14627128
|
Only OK-432 caused significant production of interleukin-12 (IL-12) p70 and interferon gamma (IFN-gamma) at both the mRNA and protein levels in imMo-DCs.
|
154 |
14627128
|
Neutralizing antibody against IL-12 p70 blocked IFN-gamma secretion from OK-432-stimulated Mo-DCs.
|
155 |
14627128
|
IL-12 p70 produced by OK-432-stimulated imMo-DCs induced secretion of IFN-gamma by CD4+ T cells.
|
156 |
14627128
|
Both secretion of IL-12 p70 and IFN-gamma and activation of NF-kappaB induced by OK-432 were suppressed when imMo-DCs were pretreated with cytochalasin B.
|
157 |
14627128
|
These results indicate that uptake of OK-432 by imMo-DCs is an early critical event for IL-12 p70 production and that NF-kappaB activation induced by OK-432 also contributes partially to IL-12 p70 production.

These results indicate that uptake of OK-432 by imMo-DCs is an early critical event for IL-12 p70 production and that NF-kappaB activation induced by OK-432 also contributes partially to IL-12 p70 production.

Moreover, cells pretreated with an inhibitor of p38 kinase (SB 208530) inhibited Gal-lectin induced TLR-2 mRNA expression by 40%.
|
166 |
14630697
|
We conclude that the Gal-lectin activates NF-kappaB and MAP kinase-signaling pathways in macrophages culminating in the induction of several genes including TLR-2 and hypothesize that this could have a significant impact on macrophage activation and contribute to amoebic pathogenesis.

In this report, we show that the coadministration of the RANK-L gene with a Trypanosoma cruzi gene markedly enhances the induction of Trypanosoma Ag-specific CD8(+) T cells and improves the DNA vaccine efficacy.
|
170 |
14662831

A similarly potent adjuvant effect of the RANK-L gene on the induction of Ag-specific CD8(+) T cells was also observed when recombinant influenza virus expressing murine malaria Ag was used as an immunogen.

The gene product Murr1 restricts HIV-1 replication in resting CD4+ lymphocytes.
|
178 |
14685242
|
Here we show that Murr1, a gene product known previously for its involvement in copper regulation, inhibits HIV-1 growth in unstimulated CD4+ T cells.
|
179 |
14685242
|
Knockdown of Murr1 increased NF-kappaB activity and decreased IkappaB-alpha concentrations by facilitating phospho-IkappaB-alpha degradation by the proteasome.
|
180 |
14685242
|
Murr1 was detected in CD4+ T cells, and RNA-mediated interference of Murr1 in primary resting CD4+ lymphocytes increased HIV-1 replication.

The core enhancer and promoter sequences of the SIV macaque 239nefstop strain (NF-kappaB/Sp1 region from -114 bp to mRNA start) have been exchanged for those of the human cytomegalovirus immediate-early promoter (CMV-IE; from -525 bp to mRNA start).

Mice treated intranasally with interleukin-10 or with a specific cell-permeable peptide that blocks the association of the catalytic subunit IKKbeta with the regulatory protein NEMO showed a striking reduction of lung NF-kappaB DNA binding activity, chemokine gene expression, and airway inflammation in response to RSV infection.

Chloroquine and related anti-malarial drugs appear to promote apoptosis in T-cells by suppressing NF-kappa-B, which enhances the expression of anti-apoptotic proteins (e.g., Bcl-2).
|
184 |
14975502
|
It appears that in the case of HIV, the increased resistance to apoptosis is provided by expression of Bcl-2 and suppression of p53.
|
185 |
14975502
|
Hence, drugs that suppresses Bcl-2 or restore p53 function might be effective in restoring the parity of resistance to apoptosis between infected and uninfected cells.
|
186 |

RNA interference technology has been used to modulate dendritic cell (DC) function by targeting the expression of genes such as IL-12 and NF-kappa B.

|
Inhibition of IL-10 by siRNA was accompanied by increased CD40 expression and IL-12 production after maturation, which endowed DC with the ability to significantly enhance allogeneic T cell proliferation.
|
188 |
15162438
|
IL-10 siRNA transfection did not affect MHC class II, CD86, CD83, or CD54 expression in mature DC.
|
189 |
15162438
|
To further test the ability of IL-10 siRNA-treated DC to induce a T cell response, naive CD4 T cells were stimulated by autologous DC pulsed with KLH.
|
190 |
15162438
|
The results indicated that IL-10 siRNA-transfected DC enhanced Th1 responses by increasing IFN-gamma and decreasing IL-4 production.

CD137 (4-1BB), is an inducible T-cell costimulatory receptor and a member of the tumor necrosis factor receptor (TNFR) superfamily.
|
192 |
15181282
|
The natural counter receptor for CD137 is 4-1BB ligand, a member of the TNF superfamily that is weakly expressed on naïve or resting B cells, macrophages, and DCs.
|
193 |
15181282
|
In T cells CD137-induced signals lead to the recruitment of TRAF family members and activation of several kinases, including ASK-1, MKK, MAPK3/ MAPK4, p38, and JNK/SAPK.
|
194 |
15181282
|
Kinase activation is then followed by the activation and nuclear translocation of several transcription factors, including ATF-2, Jun, and NF-kappaB.
|
195 |
15181282
|
In addition to augmenting suboptimal TCR-induced proliferation, CD137-mediated signaling protects T cells, and in particular, CD8+ T cells from activation-induced cell death (AICD).

CD26 up-regulates expression of CD86 on antigen-presenting cells by means of caveolin-1.
|
202 |
15353589
|
We now demonstrate that CD26 binds Caveolin-1 on antigen-presenting cells, and that residues 201-211 of CD26 along with the serine catalytic site at residue 630 contribute to binding to caveolin-1 scaffolding domain.
|
203 |
15353589
|
In addition, after CD26-caveolin-1 interaction on TT-loaded monocytes, caveolin-1 is phosphorylated, which links to activate NF-kappaB, followed by up-regulation of CD86.
|
204 |
15353589
|
Finally, reduced caveolin-1 expression on monocytes inhibits CD26-mediated CD86 up-regulation and abrogates CD26 effect on TT-induced T cell proliferation.
|
205 |
15353589
|
Taken together, these results strongly suggest that CD26-caveolin-1 interaction plays a role in the up-regulation of CD86 on TT-loaded monocytes and subsequent engagement with CD28 on T cells, leading to antigen-specific T cell activation.

Porin of Shigella dysenteriae type 1 increased the mRNA levels for Toll-like receptor (TLR) 2 and TLR6 by 1.5- and 2.9-fold respectively, of peritoneal cavity B-1a and B-1b cells, implicating that coexpression of TLR2 and TLR6 is essential as a combinatorial repertoire for recognition of porin by the B-1 cells.
|
207 |
15482852
|
Among the two key TLRs, TLR2 and TLR4, which are primarily responsible for recognizing majority of the bacterial products, TLR2 and not TLR4, participates in porin recognition.
|
208 |
15482852
|
TLR2 got increased on both the B-1 cell populations whereas the TLR4 expression remained unaffected.
|
209 |
15482852
|
Both of the B-1 cell populations expressed strongly the mRNA for NF-kappaB in the presence of porin, that was 2.4-fold more than untreated control, conforming to the earlier finding that coexpression of TLR2 and TLR6, resulted in robust NF-kappaB activation for signaling.
|
210 |
15482852
|
CD80 expression got enhanced on the B-1a cells whereas CD86 got solely expressed on B-1b cells.
|
211 |
15482852

The porin-mediated induction of IgA was augmented by interleukin-6 on B-1a and B-1b cells, by 2.4- and 2.6-fold, respectively.

Cutting edge: CD28-mediated transcriptional and posttranscriptional regulation of IL-2 expression are controlled through different signaling pathways.
|
213 |
15585831
|
PI3K was identified early as a candidate for CD28 signaling, but conflicting data during the past decade has left the role of PI3K unresolved.
|
214 |
15585831
|
We show that mutation of the PI3K interaction site in the cytosolic tail of CD28 site disrupts the ability of CD28 to recruit protein kinase C-theta; to the central supramolecular activation cluster (c-SMAC) region of the immunological synapse, promote NF-kappaB nuclear translocation, and enhance IL-2 gene transcription.
|
215 |
15585831
|
In contrast, mutation of the PI3K interaction site had no effect on the ability of CD28 to enhance IL-2 mRNA stability.
|
216 |
15585831
|
These results suggest that two distinct pathways mediate CD28-induced up-regulation of IL-2 expression, a PI3K-dependent pathway that may function through the immunological synapse to enhance IL-2 transcription and a PI3K-independent pathway that induces IL-2 mRNA stability.
|

Nod1 gene silencing by small interfering RNA reduced C pneumoniae-induced IL-8 release markedly.

The data provide evidence that HPV-VLP signal DC through a pathway involving proteoglycan receptors, TLR4 and NF-kappaB, and shed light on the mechanism by which VLP stimulate immunity in the absence of adjuvants in vivo.

The current study identifies a novel class of single-stranded oligoribonucleotides (ORN) containing unmethylated CpG motifs and a poly(G) run at the 3' end (CpG ORN) that directly stimulate human CD14+CD11c+ monocytes but not dendritic cells or B cells.

Furthermore, we show that whereas mycobacterial heat shock protein 65 signals exclusively through Toll-like receptor 4, heat shock protein 70 also signals through Toll-like receptor 2.
|
233 |
15809303
|
Mycobacterial heat shock protein 65-induced NF-kappaB activation was MyD88-, TIRAP-, TRIF-, and TRAM-dependent and required the presence of MD-2.

At early times postinfection, wild-type HRSV and the NS1/NS2 deletion mutants were very similar in the ability to activate IRF-3.
|
238 |
15827150
|
However, once NS1 and NS2 were expressed significantly, they acted cooperatively to suppress activation and nuclear translocation of IRF-3.
|
239 |

|
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.
|
240 |
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.
|
241 |
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.

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.
|
244 |
15827150

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.
|
259 |
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.

The recognition leads to activation of intracellular pathways involving nuclear factor kappa B (NF-kappaB) and mitogen-activated protein kinases (MAPK), such as the c-Jun NH2-terminal kinase (JNK), and p38.
|
261 |
15925273

We show that in vitro infection with Francisella tularensis results in activation of NF-kappaB, phosphorylation of p38 and c-Jun, and secretion of TNF-alpha in adherent mouse peritoneal cells, in the mouse macrophage-like cell line J774A.1, in the human macrophage cell line THP-1, and in human peripheral blood monocytic cells.

Dengue virus nonstructural protein NS5 induces interleukin-8 transcription and secretion.
|
265 |
16103156
|
DEN2V infection of HepG2 and primary dendritic cells induced the production of interleukin-8 (IL-8), RANTES, MIP-1alpha, and MIP-1beta, whereas only IL-8 and RANTES were induced following dengue virus infection of HEK293 cells.
|
266 |
16103156
|
Transfection of a plasmid expressing NS5 or a dengue virus replicon induced IL-8 gene expression and secretion.
|
267 |
16103156
|
Reporter assays showed that IL-8 induction by NS5 was principally through CAAT/enhancer binding protein, whereas DEN2V infection also induced NF-kappaB.
|
268 |
16103156

These results indicate a role for the dengue virus NS5 protein in the induction of IL-8 by DEN2V infection.

CD26 mediates dissociation of Tollip and IRAK-1 from caveolin-1 and induces upregulation of CD86 on antigen-presenting cells.
|
270 |
16107720
|
We have previously reported that the addition of recombinant soluble CD26 resulted in enhanced proliferation of human T lymphocytes induced by the recall antigen tetanus toxoid (TT) via upregulation of CD86 on monocytes and that caveolin-1 was a binding protein of CD26, and the CD26-caveolin-1 interaction resulted in caveolin-1 phosphorylation (p-cav-1) as well as TT-mediated T-cell proliferation.
|
271 |
16107720
|
Through proteomic analysis, we identify Tollip (Toll-interacting protein) and IRAK-1 (interleukin-1 receptor-associated serine/threonine kinase 1) as caveolin-1-interacting proteins in monocytes.
|
272 |
16107720
|
We also demonstrate that following stimulation by exogenous CD26, Tollip and IRAK-1 dissociate from caveolin-1, and IRAK-1 is then phosphorylated in the cytosol, leading to the upregulation of CD86 via activation of NF-kappaB.
|
273 |
16107720
|
Binding of CD26 to caveolin-1 therefore regulates signaling pathways in antigen-presenting cells to induce antigen-specific T-cell proliferation.

Reverse transcription-polymerase chain reaction (RT-PCR) analysis demonstrated that PhIP attenuated IL-2 mRNA expression in the thymocytes and EL4 cells stimulated with phytohemagglutinin (PHA) plus phorbol 12-myristate 13-acetate (PMA).
|
276 |
16168555
|
Furthermore, an electrophoretic mobility shift assay showed that PhIP inhibited DNA binding activity of nuclear factor for immunoglobulin kappa chain in B cells (NF-kappaB), activator protein-1 (AP-1) and nuclear factor of activated T cells (NF-AT), which are known to be responsible for IL-2 transcriptional activation.
|
277 |
16168555
|
These results suggest that PhIP has potential immunosuppressive effects by inhibiting T-cell proliferation and IL-2 expression through down regulation of ROS generation and thereby inhibiting NF-kappaB, AP-1 and NF-AT activation.

Modification of cysteine by introducing either a methyl or t-butyl group in the free sulfhydryl group and replacing the guanidine group with a urea linkage in the side chain of arginine in the cysteine-rich and arginine-rich Tat peptide sequences completely blocked the ability of these peptides to induce HIV replication, chemokine receptor CCR-5 expression, and NF-kappaB activity in monocytes.

Chlorophyllin attenuates IFN-gamma expression in lipopolysaccharide-stimulated murine splenic mononuclear cells via suppressing IL-12 production.
|
283 |
16275627
|
RT-PCR analysis showed that LPS-activated IFN-gamma expression gradually declined by CHL treatment in a dose dependent manner while mRNA production of TNF-alpha, IL-2, and FasL was not changed.
|
284 |
16275627
|
CHL also suppressed IL-12 production (p70, a heterodimer of p40 and p35) and the mRNA expression of IL-12 p40 and IL-12 receptors (both IL-12Rbeta1 and IL-12Rbeta2), which are involved in the induction of IFN-gamma expression.
|
285 |
16275627
|
Furthermore, an electrophoretic mobility shift assay showed that CHL inhibited DNA binding activity of NF-kappaB, STAT-3, and STAT-4 to their cognate DNA recognition motifs, all of which contribute to the IL-12-induced IFN-gamma transcription.
|
286 |
16275627
|
Exogenous addition of recombinant IL-12 abrogated the inhibitory effect of CHL on IFN-gamma and its mRNA expression in LPS-activated splenocytes.
|
287 |
16275627
|
Collectively, these results show that CHL inhibits IFN-gamma production by LPS-stimulated splenic mononuclear cells due to down-regulation of IL-12 production.

Differential regulation of osteoblast activity by Th cell subsets mediated by parathyroid hormone and IFN-gamma.

290 |
16339569
|
In primary osteoblasts cultured in Th2 cell condition medium, the alkaline phosphatase (ALP) activity was maintained at a basal level.
|
291 |
16339569
|
However, antagonizing PTH in the condition medium resulted in a significant reduction of the ALP activity.
|
292 |
16339569
|
Conversely, treatment of osteoblasts with IFN-gamma suppressed the ALP activity.
|
293 |
16339569
|
In addition, the Th2 cytokine environment also regulated to expression of receptor activator of NF-kappaB ligand and osteoprotegerin through both PTH-dependent and -independent mechanisms.

Furthermore, CHL attenuated the activation of NF-kappaB, NF-IL6 and AP-1, which are known to be responsible for IL-1beta gene expression, as determined by an electrophoretic mobility shift assay and an in vitro transfection assay using p(NF-kappaB)3-CAT, p(NF-IL6)3-CAT, and p(AP-1)3-CAT, respectively.

We studied the mechanisms of IL-8 induction, using luciferase reporter constructs, and the effect of pharmacological inhibitors of either IL-8 secretion or nuclear factor- kappa B (NF-kappa B) activation on IL-8 induction by dengue 2 virus (DEN2V) infection.
|
312 |
16544247

Engagement of CD28 outside of the immunological synapse results in up-regulation of IL-2 mRNA stability but not IL-2 transcription.

During T cell activation by APC, CD28 is colocalized with TCR in the central supramolecular activation cluster (cSMAC) region of the immunological synapse.

317 |
16585571
|
CD28 signaling through PI3K results in the recruitment of protein kinase C (PKC)theta to the cSMAC, activation of NF-kappaB, and induction of IL-2 transcription.
|
318 |
16585571

To test this model we have examined the mechanism of CD28-mediated induction of IL-2 secretion when CD28 is engaged outside of the immunological synapse.
|
319 |
16585571
|
CD4 T cells were stimulated with Ag presented by B7-negative APC and CD28 costimulation was provided in trans by anti-CD28-coated beads or by class II-negative, B7-positive cells.
|
320 |
16585571
|
We show that induction of IL-2 secretion under these conditions did not require expression of PKCtheta and did not induce NF-kappaB activation or IL-2 transcription.
|
321 |
16585571
|
In contrast, CD28 costimulation in trans did induce IL-2 mRNA stability, accounting for the up-regulation of IL-2 secretion.
|
322 |
16585571
|
These data indicate that the ability of CD28 to up-regulate IL-2 transcription requires colocalization of TCR and CD28 at the plasma membrane, possibly within the cSMAC of the immunological synapse.
|
323 |
16585571
|
In contrast, the ability of CD28 to promote IL-2 mRNA stability can be transduced from a distal site from the TCR, suggesting that signal integration occurs downstream from the plasma membrane.

|
Here, we report that PRMT2 inhibits NF-kappaB-dependent transcription and promotes apoptosis.
|
335 |
16648481

PRMT2 exerted this effect by blocking nuclear export of IkappaB-alpha through a leptomycin-sensitive pathway, increasing nuclear IkappaB-alpha and decreasing NF-kappaB DNA binding.

PRMT2 also rendered cells susceptible to apoptosis by cytokines or cytotoxic drugs, likely due to its effects on NF-kappaB.

Here, we report that PRMT2 inhibits NF-kappaB-dependent transcription and promotes apoptosis.
|
359 |
16648481
|
PRMT2 exerted this effect by blocking nuclear export of IkappaB-alpha through a leptomycin-sensitive pathway, increasing nuclear IkappaB-alpha and decreasing NF-kappaB DNA binding.
|
360 |
16648481
|
PRMT2 also rendered cells susceptible to apoptosis by cytokines or cytotoxic drugs, likely due to its effects on NF-kappaB.
|
361 |
16648481
|
Mouse embryo fibroblasts from PRMT2 genetic knockouts showed elevated NF-kappaB activity and decreased susceptibility to apoptosis compared to wild-type or complemented cells.
|
362 |
16648481
|
Taken together, these data suggest that PRMT2 inhibits cell activation and promotes programmed cell death through this NF-kappaB-dependent mechanism.

|
The HCMV inhibition of IL-1 and TNF-alpha pathways corresponded to a suppression of NF-kappaB activation.
|
368 |

The porin-induced profile of MIP-1alpha, MIP-1beta and RANTES showed strong bias for chemokines correlated with M1 polarization.
|
390 |

|
Intracellular expression and release of TNF-alpha and IL-12 in presence of porin was found to be TLR2 and NF-kappaB dependent.
|
391 |

Both events require binding of Inv to beta1 integrins, which initiates signaling cascades including activation of focal adhesion complexes, Rac1, mitogen-activated protein kinase, and NF-kappaB.

OVA-specific CD4 T cells produced both gamma interferon (IFN-gamma) and IL-4 as determined by enzyme-linked immunosorbent assay.
|
399 |
16790806
|
Likewise, pronounced OVA-specific CD8 T-cell responses associated with IFN-gamma production were observed.
|
400 |
16790806
|
Together, these results suggest that Inv might be an attractive tool in vaccination as it confers both host cell uptake and adjuvant activity by engagement of beta1 integrins of host cells, which leads to CD4 as well as CD8 T-cell responses.

A role for the transcription factor RelB in IFN-alpha production and in IFN-alpha-stimulated cross-priming.
|
402 |
16810633
|
Although plasmacytoid dendritic cell numbers were similar, serum interferon (IFN)-alpha levels in RelB(-/-) and RelB(+/-) chimeras were markedly lower than in RelB(+/+) chimeras during early LCMV infection.
|
403 |
16810633
|
Further, both RelB(-/-) and RelB(+/-) chimeras mounted a lower-magnitude LCMV-specific CD8(+) T cell response than their RelB(+/+) counterparts, although the LCMV-specific CD8(+) T cells present were differentiated into functional cytotoxic cells.
|
404 |
16810633
|
In LCMV-infected RelB(-/-) mice, induction of cross-priming to an independently injected soluble protein, which depends on the IFN-alpha/beta made during the viral infection, was also impaired.
|
405 |
16810633
|
Notably, provision of exogenous IFN-alpha did not restore the ability of RelB(-/-) mice to cross-prime.
|
406 |
16810633
|
In summary, these results show that the RelB/NF-kappaB pathway is required for optimal IFN-alpha production after LCMV infection and suggest a crucial role for RelB in IFN-alpha-stimulated cross-priming of CD8(+) T cell responses.

Regulation of lipopolysaccharide-induced interleukin-12 production by activation of repressor element GA-12 through hyperactivation of the ERK pathway.
|
408 |
16893987
|
In response to LPS, peritoneal macrophages produced bioactive IL-12 p70, a heterodimer (p40/p35) of subunits, but macrophage lines such as J774.1 and RAW264.7 did not.
|
409 |
16893987
|
Induction of the p35 subunit was impaired in both cell lines, and additional impairment of p40 induction was observed in RAW264.7 cells.
|
410 |
16893987
|
These results suggest that some negative regulatory mechanisms against LPS-induced IL-12 p40 production are constitutively functioning in RAW264.7 cells but not in the other types of cells.
|
411 |
16893987
|
Activation of GA-12 (a repressor element of IL-12 p40), rather than suppression of promoter elements, such as binding sites for NF-kappaB, AP-1, and IRF-1, was detected in LPS-stimulated RAW264.7 cells, accompanying hyperactivation of extracellular signal-related kinase (ERK).
|
412 |
16893987
|
Taken together, these results demonstrate that hyperactivation of the ERK pathway plays a role in upstream signaling for the activation of GA-12, leading to the repression of IL-12 p40 production in mouse macrophages.

Here, we describe an approach to enhance immunogenicity that involves the activation of NF-kappaB by the transgenic expression of an intracellular signaling molecule, NF-kappaB-inducing kinase (NIK).
|
415 |
16971487
|
In vitro, NIK increases dendritic cell antigen presentation in allogeneic and antigen-specific T cell proliferation assays by potently activating NF-kappaB and consequently up-regulating the expression of cytokines (TNF-alpha, IL-6, IL-12, IL-15, and IL-18), chemokines [IL-8, RANTES (regulated on activation, normal T cell expressed and secreted), macrophage inflammatory protein-1alpha, monocyte chemoattractant protein-1, and monocyte chemoattractant protein-3], MHC antigen-presenting molecules (class I and II), and costimulatory molecules (CD80 and CD86).
|
416 |
16971487
|
In vivo, NIK enhances immune responses against a vector-encoded antigen and shifts them toward a T helper 1 immune response with increased IgG2a levels, T cell proliferation, IFN-gamma production, and cytotoxic T lymphocyte responses more potently than complete Freund's adjuvant, a very efficacious T helper 1-inducing adjuvant.
|
417 |
16971487

These findings define NIK, and possibly other inducers of NF-kappaB activation, as a potent adjuvant strategy that offers great potential for genetic vaccine development.

Furthermore, the C16 lipopeptide was the most effective in activating dendritic cells, measured by up regulation of surface MHC Class II molecules, and also in activating NF-kappaB in a Toll-like receptor-2 (TLR2)-dependent manner.

We also discuss the contribution of specific host immune/inflammatory responses to atherogenesis, and describe cellular signaling pathways (lipopolysaccharide-binding protein [LBP], CD14, MD-2, TLR4, MyD88, and NF-kappaB, among others) that play key roles in innate immune signaling.

While the majority of serotypes utilize coxsackievirus-adenovirus receptor (CAR) as their primary attachment receptor, subgroup B and subgroup D Ad37 serotypes use CD46.
|
437 |
17108047
|
We found that CD46 Ads were capable of alpha interferon (IFN-alpha) induction by peripheral blood mononuclear cells and that plasmacytoid dendritic cells (pDCs) were the principal producers of this cytokine.
|
438 |
17108047
|
IFN-alpha induction correlated with the permissivity of pDCs to CD46- but not CAR-utilizing Ad serotypes.
|
439 |
17108047
|
A role for Toll-like receptor 9 (TLR9) recognition of Ad was supported by the requirement for viral DNA and efficient endosomal acidification and by the ability of a TLR9-inhibitory oligonucleotide to attenuate IFN-alpha induction.
|
440 |
17108047
|
Cell lines expressing TLR9 that are permissive to infection by both CAR- and CD46-utilizing serotypes showed a preferential induction of TLR9-mediated events by CD46-utilizing Ads.
|
441 |
17108047
|
Specifically, the latter virus types induced higher levels of cytokine expression and NF-kappaB activation in HeLa cells than CAR-dependent Ad types, despite equivalent infection rates.

Of the genes tested, 21 genes (IRF-1, IFN 1-2 promoter, IFNAR-1, IRF-10, IFN-gamma, 2',5'-OAS, IAP-1, caspase 8, TRAIL-like, STAT-3, IL-6, IL-8, MIP-3 alpha, MHC-I, MHC-II, TVB, GLVR-1, OTF, IL-13R alpha, ST3GAL-VI and PGK) showed an increased expression.
|
443 |
17143781
|
The remaining seven genes (IFNAR-2, IFN-alpha, NF-kappaB subunit p65, BLRcp38, DDX1, G6PDH and UB) showed a constant expression or only slight alteration.

FACS analysis demonstrated an up-regulation of DC maturation markers CD80, CD86, CD40 and MHC class II upon exposure to Gal-lectin.

445 |
17219364

The activation of DC by Gal-lectin was mediated by MAPK and NF-kappaB.
|
446 |
17257568
|
Although the mechanisms responsible for induction of these chemokines and cytokines are unclear, studies on the closely related human (H)RSV suggest that activation of NF-kappaB via TLR4 and TLR3 signalling pathways is involved.

|
F. tularensis LVS replicates in macrophages; however, bacterial replication was not required for TLR2 signaling because LVSDeltaguaA, an F. tularensis LVS guanine auxotroph that fails to replicate in the absence of exogenous guanine, activated NF-kappaB in TLR2-transfected HEK293T cells and induced cytokine expression in wild-type macrophages comparably to wild-type F. tularensis LVS.

Mycobacterium bovis bacillus Calmette-Guerin induces CCL5 secretion via the Toll-like receptor 2-NF-kappaB and -Jun N-terminal kinase signaling pathways.
|
463 |
17989335
|
In this study, we report that stimulation of HEK293 cells expressing human TLR2 with M. bovis BCG resulted in increased CCL2 and CCL5 secretion, as determined by an enzyme-linked immunosorbent assay.
|
464 |
17989335
|
M. bovis BCG infection resulted in the activation of c-Jun N-terminal kinase (JNK), and the inhibition of JNK activity had a significant effect on M. bovis BCG-dependent CCL5 secretion in TLR2-expressing cells but no effect on M. bovis BCG-dependent CCL2 secretion from infected HEK293 cells expressing human TLR2.
|
465 |
17989335
|
The M. bovis BCG-induced CCL5 release was attenuated by sulfasalazine (a well-described inhibitor of NF-kappaB activity), BAY 11-7082 (an IkappaB phosphorylation inhibitor), and ALLN (a well-described inhibitor of NF-kappaB activation that prevents degradation of IkappaB and eventually results in a lack of translocated NF-kappaB in the nucleus).
|
466 |
17989335
|
In addition, stimulation of TLR2-expressing cells with M. bovis BCG resulted in translocation of NF-kappaB subunits from the cytoplasmic to the nuclear fraction, and stimulation of cells with M. bovis BCG activated IkappaB kinase alphabeta.
|
467 |
17989335

These findings indicate that M. bovis BCG induces CCL5 production through mechanisms that include a TLR2-dependent component that requires JNK and NF-kappaB activities.

M. bovis BCG infection resulted in the activation of c-Jun N-terminal kinase (JNK), and the inhibition of JNK activity had a significant effect on M. bovis BCG-dependent CCL5 secretion in TLR2-expressing cells but no effect on M. bovis BCG-dependent CCL2 secretion from infected HEK293 cells expressing human TLR2.
|
477 |
17989335
|
The M. bovis BCG-induced CCL5 release was attenuated by sulfasalazine (a well-described inhibitor of NF-kappaB activity), BAY 11-7082 (an IkappaB phosphorylation inhibitor), and ALLN (a well-described inhibitor of NF-kappaB activation that prevents degradation of IkappaB and eventually results in a lack of translocated NF-kappaB in the nucleus).
|
478 |
17989335
|
In addition, stimulation of TLR2-expressing cells with M. bovis BCG resulted in translocation of NF-kappaB subunits from the cytoplasmic to the nuclear fraction, and stimulation of cells with M. bovis BCG activated IkappaB kinase alphabeta.
|
479 |
17989335
|
These findings indicate that M. bovis BCG induces CCL5 production through mechanisms that include a TLR2-dependent component that requires JNK and NF-kappaB activities.

481 |

497 |
18177634

498 |
18177634

Role of protein tyrosine kinase and Erk1/2 activities in the Toll-like receptor 2-induced cellular activation of murine B cells by neisserial porin.
|
527 |
18287580
|
PorB was able to induce (i) protein tyrosine kinase (PTK) activity, (ii) the phosphorylation of Erk1 and Erk2, and (iii) IkappaB-alpha phosphorylation, leading to NF-kappaB nuclear translocation in B cells in a TLR2-dependent manner.
|
528 |
18287580
|
PorB-induced NF-kappaB nuclear translocation was not dependent on either PTK or Erk1/2 activities.
|
529 |
18287580
|
However, B-cell proliferation and the induction of increased surface expression of CD86 by PorB were dependent on PTK activity and not Erk1/2 activation.
|
530 |
18287580
|
In conclusion, PorB acts through TLR2 as a B-cell mitogen, triggering tyrosine phosphorylation of various cellular proteins that are involved in proliferation and CD86 expression, as well as the phosphorylation of Erk1/2, which is not necessary for CD86 upregulation or the proliferation of B cells.

Moraxella catarrhalis lipooligosaccharide selectively upregulates ICAM-1 expression on human monocytes and stimulates adjacent naïve monocytes to produce TNF-alpha through cellular cross-talk.
|
537 |
18363879
|
ICAM-1 upregulation on human monocytes by the LOS required surface CD14, TLR4, NF-kappaB p65 and c-Jun N-terminal kinase (JNK) activity.
|
538 |
18363879
|
Our study also revealed that the LOS-induced surface ICAM-1 expression was partially mediated through a TNF-alpha dependent autocrine mechanism and could be further augmented by lipopolysaccharide-binding protein in serum.
|
539 |
18363879
|
In addition, M. catarrhalis LOS also stimulated human monocytes to produce pro-inflammatory cytokines in both TLR4- and CD14-dependent pathways.
|
540 |
18363879
|
Furthermore, the LOS-activated human monocytes secreted a significantly high level of IL-8, and could stimulate adjacent naïve monocytes to produce TNF-alpha which was partially mediated via membrane ICAM-1 and IL-8/IL-8RA.
|
541 |
18389479
|
DiC14-amidine liposomes also activated human DC, as shown by synthesis of IL-12p40 and TNF-alpha, accumulation of IL-6, IFN-beta and CXCL10 mRNA, and up-regulation of membrane expression of CD80 and CD86.
|
542 |
18389479
|
DC stimulation by diC14-amidine liposomes was associated with activation of NF-kappaB, ERK1/2, JNK and p38 MAP kinases.
|
543 |
18389479
|
Finally, we demonstrated in mouse and human cells that diC14-amidine liposomes use Toll-like receptor 4 to elicit both MyD88-dependent and Toll/IL-1R-containing adaptor inducing interferon IFN-beta (TRIF)-dependent responses.

Porcine TLR8 and TLR7 are both activated by a selective TLR7 ligand, imiquimod.
|
545 |
18439678
|
We cloned and characterized porcine TLR7 and TLR8 genes from pig lymph node tissue.
|
546 |
18439678
|
Sequence analysis showed that the aa sequence identities of porcine TLR7 with human, mouse and bovine TLR7 are 85, 78 and 90%, respectively, whereas porcine TLR8 aa sequence identities with human, mouse and bovine TLR8 are 73, 69 and 79%, respectively.
|
547 |
18439678
|
Both porcine TLR7 and TLR8 proteins were expressed in cell lines and were N-glycosylated.
|
548 |
18439678
|
The stimulatory activity of TLR7 and TLR8 ligands to porcine and human TLR7 and TLR8 in transiently transfected Cos-7 and 293T cells were analyzed using a NF-kappaB reporter assay.
|
549 |
18439678
|
Two imidazoquinoline molecules, imiquimod and gardiquimod, markedly activated both porcine TLR7 and TLR8 whereas only human TLR7, but not TLR8, was activated by the ligands.
|
550 |
18439678
|
We further showed that porcine TLR7 and TLR8 are located intracellularly and are mainly within the endoplasmic reticulum.
|
551 |
18449425
|
We found that DV up-regulates Protease Activated receptor type-1 (inflammation) and TF (coagulation) receptors, via the phosphorylation of p38 and ERK1/2 MAPKs, which favor the activation of NF-kappaB transcription factor.
|
552 |
18449425
|
This induces pro-inflammatory (IL-8) or pro-adhesive (VCAM-1) gene expression which may lead to EVC activation.

Antibodies to proteinase 3 prime human oral, lung, and kidney epithelial cells to secrete proinflammatory cytokines upon stimulation with agonists to various Toll-like receptors, NOD1, and NOD2.
|
558 |
18495849
|
In this study, anti-PR3 antibodies (Abs) and PR3 ANCA-containing sera from WG patients endowed human oral, lung, and kidney epithelial cells with responsiveness to PAMPs in terms of the production of proinflammatory cytokines, such as interleukin-6 (IL-6), IL-8, monocyte chemoattractant protein-1, and tumor necrosis factor alpha.
|
559 |
18495849
|
Protease-activated receptor-2 (PAR-2) agonist peptides mimicked the priming effects of PR3 ANCA against PAMPs.
|
560 |
18495849

Compared to rhMPV-WT, rhMPV-Delta G also increased IRF- and NF-kappaB-dependent gene transcription, which was reversely inhibited by G protein expression.
|
562 |
18516301
|
Since RNA helicases have been shown to play a fundamental role in initiating viral-induced cellular signaling, we investigated whether retinoic induced gene (RIG)-I was the target of G protein inhibitory activity.

Although human B cells bound both human and murine BLyS, nuclear accumulation of NF-kappaB p52, an indication of the induction of a protective anti-apoptotic response, following stimulation with human BLyS was more robust than that induced with murine BLyS suggesting a fundamental disparity in BLyS receptor signaling.
|

Vibrio cholerae flagellins induce Toll-like receptor 5-mediated interleukin-8 production through mitogen-activated protein kinase and NF-kappaB activation.
|
587 |
18809662
|
Bacterial flagellins are known to induce IL-8 production through Toll-like receptor 5 (TLR5).
|
588 |
18809662
|
Since the V. cholerae genome encodes five distinct flagellin proteins, FlaA to FlaE, with homology to conserved TLR5 recognition regions of Salmonella FliC, we hypothesized that V. cholerae flagellins may contribute to IL-8 induction through TLR5 and mitogen-activated protein kinase (MAPK) signaling.
|
589 |
18809662
|
Each purified recombinant V. cholerae flagellin induced IL-8 production in T84 intestinal epithelial cells and also induced nuclear factor kappa B (NF-kappaB) activation in HEK293T/TLR5 transfectants, which was blocked by cotransfection with a TLR5 dominant-negative construct, demonstrating TLR5 specificity.
|
590 |
18809662
|
Supernatants derived from Delta flaAC and Delta flaEDB mutants induced IL-8 production in HT-29 intestinal epithelial cells and in HEK293T cells overexpressing TLR5, whereas Delta flaABCDE supernatants induced significantly less IL-8 production, demonstrating the contribution of multiple flagellins in IL-8 induction.
|
591 |
18809662
|
Purified recombinant V. cholerae FlaA activated the MAPKs p38, c-jun N-terminal kinase (JNK), and extracellular regulated kinase (ERK) in T84 cells.
|
592 |
18809662
|
FlaA-induced IL-8 production in T84 cells was inhibited by the p38 inhibitor in combination with either the JNK or ERK inhibitors.
|
593 |
18809662
|
Collectively, these data suggest that V. cholerae flagellins are present in culture supernatants and can induce TLR5- and MAPK-dependent IL-8 secretion in host cells.

Each purified recombinant V. cholerae flagellin induced IL-8 production in T84 intestinal epithelial cells and also induced nuclear factor kappa B (NF-kappaB) activation in HEK293T/TLR5 transfectants, which was blocked by cotransfection with a TLR5 dominant-negative construct, demonstrating TLR5 specificity.

|
Supernatants derived from Delta flaAC and Delta flaEDB mutants induced IL-8 production in HT-29 intestinal epithelial cells and in HEK293T cells overexpressing TLR5, whereas Delta flaABCDE supernatants induced significantly less IL-8 production, demonstrating the contribution of multiple flagellins in IL-8 induction.

Purified recombinant V. cholerae FlaA activated the MAPKs p38, c-jun N-terminal kinase (JNK), and extracellular regulated kinase (ERK) in T84 cells.
|
600 |
18809662
|
FlaA-induced IL-8 production in T84 cells was inhibited by the p38 inhibitor in combination with either the JNK or ERK inhibitors.
|
601 |
18809662
|
Collectively, these data suggest that V. cholerae flagellins are present in culture supernatants and can induce TLR5- and MAPK-dependent IL-8 secretion in host cells.

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.
|
603 |
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.
|
604 |
18941233
|
DAI binds to and colocalizes with endogenous RIP1 at characteristic cytoplasmic granules.
|

Suppression of RIP1 expression by RNAi abrogates NF-kappaB activation as well as IFNbeta induction by immunostimulatory DNA.
|
606 |

DAI also interacts with RIP3 and this interaction potentiates DAI-mediated activation of NF-kappaB, implicating RIP3 in regulating this RHIM-dependent pathway.
|
607 |
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.

During T cell interaction with APC, CD28 is recruited to the central region (cSMAC) of the immunological synapse.
|
634 |
19017952
|
CD28-mediated signaling through PI3K results in the recruitment of protein kinase C-theta (PKCtheta) to the cSMAC, activation of NF-kappaB, and up-regulation of IL-2 transcription.
|
635 |
19017952
|
In this report, we show that CD28 recruitment and persistence at the immunological synapse requires TCR signals and CD80 engagement.
|
636 |

|
Addition of mAb to either MHC class II or CD80 results in the rapid displacement of CD28 from the immunological synapse.
|
637 |
19017952
|
Ligand binding is not sufficient for CD28 localization to the immunological synapse, as truncation of the cytosolic tail of CD28 disrupts synapse localization without effecting the ability of CD28 to bind CD80.
|
638 |

|
Mutation of tyrosine 188 also results in diminished activation of NF-kappaB, suggesting that CD28-mediated localization of PKCtheta to the cSMAC is important for efficient signal transduction.

We previously reported that LPS-induced de novo expression of RelB is required for generating tolerance to interleukin-1beta (IL-1beta) and tumor necrosis factor alpha (TNF-alpha) expression.
|
646 |
19020113
|
RelB represses transcription by binding with heterochromatic protein 1 alpha (HP1alpha) to the proximal promoters of IL-1beta and TNF-alpha.
|
647 |
19020113
|
In contrast, we report herein that RelB is required for sustained expression of anti-inflammatory IkappaBalpha in LPS-tolerant THP-1 cells.
|
648 |
19020113
|
RelB transcription activation requires binding to the IkappaBalpha proximal promoter along with NF-kappaB p50 and is associated with an apparent dimer exchange with p65.

We therefore expressed a viral protein that constitutively activates NF-kappaB, vFLIP from Kaposi's sarcoma-associated herpesvirus (KSHV), in a lentivector to mature DCs. vFLIP activated NF-kappaB in mouse bone marrow-derived DCs in vitro and matured these DCs to a similar extent as lipopolysaccharide; costimulatory markers CD80, CD86, CD40, and ICAM-1 were upregulated and tumor necrosis factor alpha and interleukin-12 secreted.

A20 down-regulated DCs showed higher activation of the transcription factors NF-kappaB and activator protein-1, which resulted in increased and sustained production of IL-6, IL-10, and IL-12p70.
|
652 |
19124729
|
We further demonstrated that A20 down-regulated DCs skew naive CD4+ T cells toward IFN-gamma producing Th1 cells, a process which is dependent on IL-12p70 and which is unaffected by IL-10.
|
653 |
19124729
|
Furthermore, A20 and/or IL-10 down-regulated DCs had an enhanced capacity to prime Melan-A/MART-1 specific CD8+ T cells.
|
654 |
19124729
|
Finally, we demonstrated that potent T cell stimulatory DCs are generated by the simultaneous delivery of poly(I:C12U), A20, or A20/IL-10 small interfering RNA and Ag-encoding mRNA, introducing a one step approach to improve DC-based vaccines.
|
655 |
19124729
|
Together these findings demonstrate that A20 negatively regulates NF-kappaB and activator protein-1 in DCs and that down-regulation of A20 results in DCs with enhanced T cell stimulatory capacity.

Our results demonstrates that Mycobacterium bovis BCG (M. bovis BCG) downregulates tumour necrosis factor-alpha (TNF-alpha)-induced COX-2 gene expression in alveolar epithelial cells by inhibiting the phosphorylations of Raf-1 and p38 kinases.
|
662 |
19140872
|
Further, M. bovis BCG-mediated inhibition of COX-2 or p38 mitogen-activated protein kinase could be reversed by Calyculin A, a selective inhibitor of Ser/Thr phosphatases.
|
663 |

Moreover, M. bovis BCG inhibited the TNF-alpha-triggered NF-kappaB activation following IkappaB degradation.

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.

This activation process was absolutely dependent on TLR4 and CD14.
|
677 |
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 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.
|
740 |
19846517

The effect of R1, R2 and R3 on the expression of the pro- and anti-inflammatory cytokines (TNF-alpha, IL-6, and IL-12) and the co-stimulatory molecules (CD40, CD80, CD86, and MHC class II) in MDDCs was examined.
|
746 |
19853910
|
The exposure of R1 caused a dose-dependent increase in the expression of TNF-alpha, IL-12, CD86 and CD40, while R2 and R3 did not up-regulate these cytokines and co-stimulatory molecules.
|
747 |
19853910
|
Furthermore, we found that R1 significantly increased the NF-kappaB expression in the nucleus (in a dose-dependent manner) and promoted the degradation of total IkappaBalpha levels, indicating that the NF-kappaB signaling pathway might involve in an R1-induced DC activation.

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.
|
751 |
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.
|
752 |
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.
|
753 |
20039305
|
Finally, we demonstrated that splenocytes from CD14-deficient mice produce cytokines in response to CRX-527 but not to LPS.

Day 3 ROS(lo) DCs were highly responsive to TLR stimuli such as LPS and zymosan by rapid upregulation of CD80, CD86, and MHC class II, in contrast to the low response of day 6 ROS(hi) DCs.
|
756 |
20176741
|
ROS(hi) DCs could not initiate and sustain a significant level of NF-kappaB phosphorylation in response to LPS and zymosan, although demonstrating hyperactivation of p38 MAPK by LPS, in a fashion disparate to ROS(lo) DCs.
|
757 |

Since Toll-like receptor 2 (TLR2), TLR4, and TLR9 activation have been involved in HIV-1 recrudescence, we sought to determine the role of these TLRs in HIV-1 reactivation induced by the periodontal pathogens Fusobacterium nucleatum and Porphyromonas gingivalis using BF24 monocytes/macrophages stably transfected with the HIV-1 promoter driving chloramphenicol acetyltransferase (CAT) expression and THP89GFP cells, a model of HIV-1 latency.
|
826 |

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.
