|
Toll-like receptor 2 (TLR2) and TLR4 play important roles in innate immune responses to various microbial agents.
|
3 |
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.
|
4 |
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.
|
6 |
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.
|
7 |
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.
|
8 |
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.
|
9 |
11441107
|
Our data also suggest that Tollip may be an important constituent of both the TLR2 and TLR4 signaling pathways.

Cell activation by synthetic lipopeptides of the hepatitis C virus (HCV)--core protein is mediated by toll like receptors (TLRs) 2 and 4.
|
38 |
12270544
|
The cause of enhanced immunogenicity of lipopeptides is largely unknown but members of the novel family of Toll like receptors (TLR) such as TLR2 and TLR4 have been shown to mediate activation of cells in response to bacterial lipopolysaccharide (LPS) and other lipidated bacterial or viral components.
|
39 |
12270544
|
We studied TLR-mediated activation by 14 synthetic lipopeptides corresponding to T cell epitopes on hepatitis C virus (HCV) core in human embryonic kidney cells (HEK293) transiently over-expressing TLR2 and in Ba/F3 mouse bone marrow cells stably transfected with TLR4 and the adaptor molecule MD-2.
|
40 |
12270544
|
Nine of the 14 lipopeptides also stimulated luciferase activity in the TLR4/MD-2 double-transfected Ba/F3 cells but not Ba/F3 control cells.
|
41 |
12270544
|
Overall, there was a close statistical correlation between TLR2 and TLR4/MD-2-mediated cell activation by the lipopeptides.
|
42 |
12270544
|
In contrast, the corresponding free peptides had no stimulatory effect on TLR2 nor on TLR4/MD-2 transfected cells.
|
43 |
12270544
|
Thus, lipopeptides but not their corresponding free peptides can activate cells via TLRs 2 and 4.

In natural immune responses CD4+ T helper (Th) cells, reactive with peptide antigens presented by major histocompatibility complex (MHC) class II molecules on dendritic cells (DC), can drive the maturation of DC that is required for induction of CD8+ cytolytic T-lymphocyte (CTL) immunity.
|
87 |
12445291
|
Proper induction, expansion and maintenance of CTL responses are achieved through delicate interactions between CD4+ T cells, DC and CD8+ T cells involving several ligand-receptor pairs.
|
88 |
12445291
|
Th cells to a large extent operate through up-regulation of CD40L, which then interacts with CD40 on DC to cause DC maturation.
|
89 |
12445291
|
Subsequent CTL induction by activated DC requires CD80/CD86 on the DC to interact with the CD28 costimulatory receptor on CD8+ T cells.
|
90 |
12445291
|
Alternative molecular triggers of DC activation that can support induction of powerful CTL responses include agonistic anti-CD40 antibody or ligands of Toll-like receptors (TLR) such as LPS (TLR4 ligand) or oligodeoxynucleotides containing CpG-motifs (TLR9 ligand).

DCs generated from peripheral blood using granulocyte macrophage colony-stimulating factor and interleukin (IL)-4 showed immunophenotypes consistent with immature DCs (iDCs).
|
94 |
12874015
|
Furthermore, OK-DCs showed significantly higher production of IL-12 and IFN-gamma compared with DCs with other stimulations.
|
95 |
12874015
|
Furthermore, OK-432 does not activate nuclear factor kappaB through Toll-like receptor 2 or Toll-like receptor 4 in the indicator cell system; however, it induces IL-12 production through the beta(2) integrin system on DCs.

Heat-killed Brucella abortus induces TNF and IL-12p40 by distinct MyD88-dependent pathways: TNF, unlike IL-12p40 secretion, is Toll-like receptor 2 dependent.
|

|
To identify the TLR involved in HKBA recognition, we examined HKBA responses in TLR2- and TLR4-deficient animals.
|
99 |
12874236
|
TNF responses to HKBA were TLR4 independent; however, the response in TLR2-deficient mice was significantly delayed and reduced, although not completely abolished.
|
100 |
12874236
|
Studies using Chinese hamster ovary/CD14 reporter cell lines stably transfected with either human TLR2 or human TLR4 confirmed the results seen with knockout mice, namely TLR2, but not TLR4, can mediate cellular activation by HKBA.
|
101 |
12874236

In addition, human embryonic kidney 293 cells, which do not respond to HKBA, were made responsive by transfecting TLR2, but not TLR4 or TLR9.

Taken together, our data demonstrate that MyD88-dependent pathways are crucial for activation by HKBA and that TLR2 plays a role in TNF, but not IL-12p40 pathways activated by this microbial product.

Parent OM selectively up-regulated Toll-like receptor 4 (TLR4) mRNA expression and induced mo-DC maturation, as reflected by increased production of chemokines, proinflammatory cytokines, and CD83, CD80, CD86, CD40, and major histocompatibility complex (MHC) class II molecules.

125 |
14500478
|
In contrast, LPS-deficient OM selectively up-regulated TLR2 mRNA expression and induced moderate increases in both cytokine production and expression of CD86 and MHC class II molecules.
|
126 |
14505917
|
Co-formulation with compounds that targeted TLR-2, TLR-3, TLR-4, or TLR-9 elicited significantly diminished type 2 T cell responses that caused granulocytic inflammation and eosinophilia in the airways after challenge.

127 |

|
PDCs, which express TLR7 and TLR9, responded to imidazoquinolines (imiquimod and R-848) and to CpG oligodeoxynucleotides stimulation, resulting in enhancement in expression of costimulatory molecules and induction of IFN-alpha and IL-12p70.
|
128 |
14530357
|
In contrast, MDCs, which express TLR3, TLR4, and TLR7, responded to poly(I:C), LPS, and imidazoquinolines with phenotypic maturation and high production of IL-12 p70 without producing detectable IFN-alpha.
|
129 |
14530357
|
Optimally TLR ligand-stimulated PDCs or MDCs exposed to CMV or HIV-1 Ags enhanced autologous CMV- and HIV-1-specific memory T cell responses as measured by effector cytokine production compared with TLR ligand-activated monocytes and B cells or unstimulated PDCs and MDCs.

Cutting edge: different Toll-like receptor agonists instruct dendritic cells to induce distinct Th responses via differential modulation of extracellular signal-regulated kinase-mitogen-activated protein kinase and c-Fos.
|
131 |
14607893
|
Thus, Escherichia coli LPS and flagellin, which trigger TLR4 and TLR5, respectively, instruct DCs to stimulate Th1 responses via IL-12p70 production, which depends on the phosphorylation of p38 and c-Jun N-terminal kinase 1/2.
|
132 |
14607893
|
In contrast, the TLR2 agonist, Pam3cys, and the Th2 stimulus, schistosome egg Ags: 1) barely induce IL-12p70; 2) stimulate sustained duration and magnitude of extracellular signal-regulated kinase 1/2 phosphorylation, which results in stabilization of the transcription factor c-Fos, a suppressor of IL-12; and 3) yield a Th2 bias.
|
133 |
14607893
|
Thus, distinct TLR agonists differentially modulate extracellular signal-regulated kinase signaling, c-Fos activity, and cytokine responses in DCs to stimulate different Th responses.
|
134 |
15067049
|
A Toll-like receptor 2 ligand stimulates Th2 responses in vivo, via induction of extracellular signal-regulated kinase mitogen-activated protein kinase and c-Fos in dendritic cells.
|
135 |
15067049
|
Thus, Escherichia coli LPS (TLR-4 stimulus), activates DCs to produce abundant IL-12(p70), but little IL-10, and stimulates Th1 and Tc1 responses.
|
136 |
15067049
|
In contrast, Pam-3-cys (TLR-2 stimulus) elicits less IL-12(p70), but abundant IL-10, and favors Th2 and T cytotoxic 2 (Tc2) responses.
|
137 |
15067049
|
Thus, Pam-3-cys induces enhanced extracellular signal-regulated kinase signaling, compared with LPS, resulting in suppressed IL-12(p70) and enhanced IL-10 production, as well as enhanced induction of the transcription factor, c-Fos.
|
138 |
15067049
|
Interestingly, DCs from c-fos(-/-) mice produce more IL-12(p70), but less IL-10, compared with control DCs.

15109052
|
Five candidate genes were selected for study, based on their biological function as possibly affecting response to SE: toll-like receptor 4 (TLR4), T-cell specific surface protein (CD28), macrophage migration inhibitory factor (MIF), MD-2, and lipopolysaccharide-induced tumor necrosis factor (TNF)-alpha factor (LITAF).
|
141 |
15109052

The LITAF and MIF genes were homozygous for all sires.

In this study, we demonstrate that pretreatment of monocytes with human HSP60 results in a suppression of TNF-alpha production on restimulation with HSP60.
|
152 |
15214052
|
Furthermore, desensitization with HSP60 inhibits TNF-alpha expression in these cells in response to LPS stimulation, thereby inducing "cross-tolerance".
|
153 |
15214052
|
In contrast to TNF-alpha suppression, IL-1beta expression was augmented in HSP60-pretreated monocytes on restimulation, while being suppressed in THP-1 cells.
|
154 |
15214052
|
Addition of an anti-IL-10 neutralizing antibody had no significant effect on HSP60- or LPS-induced tolerance.HSP60 priming of monocytes also results in significant down-regulation of HLA-DR, CD86 and Toll-like receptor 4 expression, but minimally up-regulates CD80 expression, similar to that previously reported with LPS.
|
155 |
15214052
|
By identifying a previously unrecognized "tolerizing" effect of extended exposure to autologous HSP60 on the innate immune system, as opposed to its recently identified pro-inflammatory stimulatory capacity, this study highlights a further level of complexity of our understanding of the biological activities of HSP.

IL-6 and IL-10 induction from dendritic cells in response to Mycobacterium tuberculosis is predominantly dependent on TLR2-mediated recognition.

A key new finding of this study is that production of IL-6 and IL-10 from dendritic cells in response to M. tuberculosis is principally dependent on TLR2.
|
159 |
15322203
|
The study also indicates that M. tuberculosis can induce IL-12 production in the absence of either TLR2 or TLR4, suggesting redundancy or possibly involvement of other receptors in IL-12 production.
|
160 |
15322203
|
In addition, the data also reveal that lack of TLR2 or TLR4 does not impact on dendritic cell maturation or on their ability to influence the polarity of differentiating naive T cells.

Collectively, data presented here provide a mechanistic insight for the contribution of TLR2 and TLR4 to tuberculosis disease progression and offer strategies for regulating IL-6 and IL-10 production in dendritic cell-based vaccine strategies.

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.
|

Zymosan, poly(I:C) and CpG DNA, which signal through TLR2/6, 3 and 9, respectively, were found to strongly induce the production of IgG2a antibodies, whereas R-848 (TLR7) and LPS (TLR4) did so much more weakly.
|
193 |
15550117
|
In contrast, LPS, poly(I:C) and CpG DNA, but not zymosan, induced functional CD8+ T-cell responses against OVA; peptidoglycan (TLR2/?)
|
194 |
15550117
|
In addition, our results demonstrate that the ability of TLR stimuli to initiate CD8+ T-cell responses against soluble protein antigens is largely dependent on the IFN-alpha/beta signalling pathway.

Porin of Shigella dysenteriae type 1 increased the mRNA levels for Toll-like receptors TLR2 and TLR6, by 1.8-fold and twofold, respectively, in peritoneal cavity B-2 cells from C57BL/6 mice, implicating that the co-expression of TLR2 and TLR6 occurs as a combinatorial repertoire in response to porin.

15629885
|
Upon stimulation with LPS, in comparison with young MPhi, aged MPhi secreted reduced amounts of IL-6, tumor necrosis factor alpha, IL-1beta, and IL-12, cytokines necessary for B cells to respond to TI Ag.
|
204 |
15629885
|
As aged MPhi have a reduced number of cells expressing Toll-like receptor 4 and CD14, the imbalance in cytokine production might be partly a result of fewer cells expressing key components of the LPS receptor complex.

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.

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.
|
221 |
15809303
|
Mycobacterial heat shock protein 65-induced NF-kappaB activation was MyD88-, TIRAP-, TRIF-, and TRAM-dependent and required the presence of MD-2.

M. tuberculosis HSP70-OVA fusion protein enhanced cross-processing by a CD91-dependent process that was independent of TLR4 and MyD88.
|
223 |
15843516
|
These results indicate that HSPs enhance delivery and cross-processing of HSP-linked Ag by B cells, which could provide a novel contribution to the generation of CD8(+) T cell responses.
|
224 |
15843516
|
HSP fusion proteins have potential advantages for use in vaccines to enhance priming of CD8(+) T cell responses.

This formulation was found to effectively elicit CD8+ cytotoxic T cell (CTL) responses in an HLA-A*0201 transgenic mouse model.
|
226 |
15855013
|
Co-administration of the peptide-microspheres with adjuvants, including granulocyte-macrophage colony stimulating factor, MPL adjuvant and select synthetic Toll-Like Receptor 4 ligands, the aminoalkyl glucosaminide-4 phosphates, significantly augmented CTL responses.

HPV16 L1 VLP also activate production of proinflammatory factors IFN-alpha, IL-6, MIP-1alpha, RANTES, and KC, up-regulate the expression of costimulatory molecules by naive B cells, and increase the B1 B cell subpopulation.
|
228 |
15944297

Thus HPV16 L1 VLP directly activate B cells to induce CD4(+) T cell independent humoral immune responses via TLR4- and MyD88-dependent signaling.

All PPS-containing preparations induced IL-6 and TNF-alpha from wild-type, but not TLR2-/-, macrophages.
|
230 |
16116197

The commercial 23-valent PPS vaccine, Pneumovax-23 also contained TLR ligands (TLR2 and TLR4), which were absolutely critical for the IgG-inducing activity of the vaccine in mice.

Are mineral adjuvants triggering TLR2/TLR4 on dendritic cells by a secondary cascade reaction in vivo through the action of heat shock proteins and danger signals?

|
When T-cell responses were compared in allogeneic mixed leukocyte reaction, DCs stimulated with Ribomunyl induced higher levels of IFNgamma than DCs stimulated with the cytokine cocktail: tumor necrosis factor-alpha, IL-1beta, IL-6, and prostaglandin E2.
|
233 |
16224278
|
In the presence of IL-10 neutralizing antibodies, DC IL-12p70 production and T-cell IFNgamma were increased in vitro.
|
234 |
16224278
|
Similarly, DCs stimulated with Ribomunyl, IFNgamma, and anti-IL-10 induced high levels of tetanus toxoid-specific T-cell proliferation and IFNgamma secretion.
|
235 |
16224278
|
Thus, MoDCs generated in SFM efficiently stimulate T-cell IFNgamma production after maturation in the presence of a clinical-grade TLR4 agonist and IL-10 neutralization.
|
236 |
16246469
|
However, both wild type meningococcal LOS and KDO(2)-lipid A, significantly up-regulated CD80, CD83 and CD86 and released significantly higher amounts of IL-12p70, IL-6, IL-10, TNFalpha, MCP-1, IP-10 and RANTES.
|
237 |
16246469
|
Further, DCs stimulated with wild type or KDO(2)-lipid A but not meningococcal lipid A or penta-acylated KDO(2)-lipid A stimulated naïve allogeneic CD4+ T cells to secrete enhanced levels of IFN-gamma, relative to T cells primed with immature DCs.
|
238 |
16246469
|
In contrast to Escherichia coli LPS, IL-5 production was enhanced or maintained in CD4+ T-cells stimulated with MDDC exposed to wild-type meningococcal LOS and KDO(2)-lipid A.
|
239 |
16246469
|
These data suggest that KDO linked to a fully acylated meningococcal lipid A is required for meningococcal endotoxin's immunostimulatory activity of human MDDC via TLR4/MD-2 and that different endotoxin structures influence Th responses mediated by MDDC.

We recently demonstrated that the pattern recognition receptors (PRRs) toll-like receptor 2 (TLR2), TLR4, and CD14 are expressed in mouse colonic epithelium in a compartmentalized manner.
|
241 |
16426010
|
Interestingly, while TLR2, TLR4, and CD14 were up-regulated in the inflamed colon, TLR5 was down-regulated at both the mRNA and protein levels.
|
242 |
16426010
|
Additional in vitro studies using a mouse cell line, Colon-26, showed that gamma interferon (IFN-gamma) time- and dose-dependently down-regulates TLR5.
|
243 |
16426010
|
TLR5 expression is down-regulated in vivo during acute and chronic DSS-induced colitis, in contrast to the expression of TLR2, TLR4, and CD14.
|
244 |
16426010
|
Finally, IFN-gamma may be involved in down-regulating TLR5 expression.

We recently demonstrated that the pattern recognition receptors (PRRs) toll-like receptor 2 (TLR2), TLR4, and CD14 are expressed in mouse colonic epithelium in a compartmentalized manner.
|
246 |
16426010
|
Interestingly, while TLR2, TLR4, and CD14 were up-regulated in the inflamed colon, TLR5 was down-regulated at both the mRNA and protein levels.
|
247 |
16426010
|
Additional in vitro studies using a mouse cell line, Colon-26, showed that gamma interferon (IFN-gamma) time- and dose-dependently down-regulates TLR5.
|
248 |
16426010
|
TLR5 expression is down-regulated in vivo during acute and chronic DSS-induced colitis, in contrast to the expression of TLR2, TLR4, and CD14.
|
249 |
16426010

Finally, IFN-gamma may be involved in down-regulating TLR5 expression.

MyD88 knockout (KO) mice, but not TLR2-, TLR4- or TLR9-deficient mice, rapidly succumbed following in vivo bacterial infection via the intradermal route even with a very low dose of LVS (5 x 10(1)) that was 100,000-fold less than the LD(50) of normal wild-type (WT) mice.
|
256 |
16513388
|
By day 5 after LVS infection, bacterial organ burdens were 5-6 logs higher in MyD88 knockout mice; further, unlike infected WT mice, levels of interferon-gamma in the sera of LVS-infected MyD88 KO were undetectable.

Nucleotide-binding oligomerization domain 2 (Nod2) pathways are known to interact with Toll-like receptor 2 (TLR2) and TLR4, which are pattern recognition receptors for Candida albicans.
|
258 |
16548886
|
In this study we analyse the interaction of the MP from Candida albicans (MP65) with dendritic cells (DC) and demonstrate that MP65 stimulates DC and induces the release of TNF-alpha, IL-6 and the activation of IL-12 gene, with maximal value 6 h post treatment.
|
259 |
16548886
|
The latter effect is partly mediated by toll-like receptor 2 (TLR2) and TLR4, and the MyD88-dependent pathway is involved in the process.

Splenocytes from infected C3H/HeJ mice produced almost no interleukin-1beta (IL-1beta) and tumor necrosis factor alpha (TNF-alpha) upon ex vivo restimulation with B. pertussis compared to A/J mice and also showed a delayed gamma interferon (IFN-gamma) production.

In contrast to most LPS, highly purified Ft LVS LPS (10 microg/ml) was found to be only minimally stimulatory in primary murine macrophages and in HEK293T cells transiently transfected with TLR4/MD-2/CD14, whereas live Ft LVS bacteria were highly stimulatory for macrophages and TLR2-expressing HEK293T cells.

Modification of TLR-induced activation of human dendritic cells by type I IFN: synergistic interaction with TLR4 but not TLR3 agonists.
|
264 |
16783851
|
Type I interferon (IFN-alpha/beta), which includes a large family of closely related infection-inducible cytokines, represents one indirect signal that can act as a DC stimulus.
|
265 |
16783851
|
We have investigated the ability of IFN-alpha/beta subtypes to affect DC function and to influence DC responses to Toll-like receptor (TLR) agonists (i.e., direct infection-associated signals).
|
266 |
16783851
|
Subtle differences were observed among 15 subtypes of IFN-alpha/beta in the ability to stimulate expression of maturation markers and chemokines by human monocyte-derived DC, with IFN-omega being the most unique in its effects.
|
267 |
16783851
|
Pre-treatment with IFN-alpha/beta did not alter the ability of DC to mature in response to subsequent contact with TLR agonists, but did modulate their secretion of chemokines.
|
268 |
16783851
|
Conversely, IFN-alpha/beta was shown to act synergistically with TLR4 but not TLR3 agonists for the induction of maturation and chemokine production when DC were exposed to IFN-alpha/beta and TLR ligands simultaneously.
|
269 |
16783851
|
Taken together, these results indicate a complex role for IFN-alpha/beta in regulating DC function during the course an infection, which varies according to IFN-alpha/beta subtype and the timing of exposure to other stimuli.

The role of TLRs during infection with Mycobacterium bovis Bacillus Calmette-Guérin (BCG) has been evaluated for TLR2 and TLR4 only.
|
278 |
16920494
|
To identify the set of TLRs involved in the recognition of BCG, we infected bone marrow-derived macrophages and bone marrow-derived dendritic cells (Flt3-ligand generated DCs) from TLR2, TLR3, TLR4, TLR7, TLR9, MyD88 knockout, TLR2/4 and TLR2/4/9 multiple knockout mice.
|
279 |
16920494
|
The degree of activation and stimulation was determined by TNFalpha, IL-6 and IL-12p40 ELISA.
|
280 |
16920494
|
Both macrophages and DCs produce markedly decreased amounts of TNFalpha and IL-6 in the absence of TLR2 whereas no significant reduction could be observed for TLR3, 4, 7, 9 single TLR-knockouts.
|
281 |
16920494
|
Similarly, up-regulation of CD86 is abolished only in TLR2/4/9-deficient DCs supporting a role of TLR9 in the recognition of M. bovis BCG by murine dendritic cells.

Induction of long-term lipopolysaccharide tolerance by an agonistic monoclonal antibody to the toll-like receptor 4/MD-2 complex.
|
290 |
17028215
|
We have established an agonistic monoclonal antibody, UT12, that induces stimulatory signals comparable to those induced by lipopolysaccharide (LPS) through Toll-like receptor 4 and MD-2.
|
291 |
17028215
|
UT12 activated nuclear factor kappaB and induced the production of proinflammatory cytokines such as tumor necrosis factor alpha (TNF-alpha) and interleukin-6 (IL-6) in peritoneal exudative cells.
|
292 |
17028215
|
In addition, mice injected with UT12 rapidly fell into endotoxin shock concomitant with the augmentation of serum TNF-alpha and IL-6 levels, followed by death within 12 h.
|
293 |
17028215
|
On the other hand, when the mice were pretreated with a sublethal dose of UT12, the mice survived the subsequent lethal LPS challenges, with significant suppression of serum TNF-alpha and IL-6, indicating that UT12 induced tolerance against LPS.

In this study, we showed that ovalbumin (OVA) protein-pulsed DC (DC(OVA))-derived EXO (EXO(OVA)) displayed MHC class I-OVA I peptide (pMHC I) complexes, CD11c, CD40, CD80, CCR7, DEC205, Toll-like receptor 4 (TLR4), TLR9, MyD88 and DC-SIGN molecules, but at a lower level than DC(OVA).
|
325 |
17073943

EXO(OVA) can be taken up by DC through LFA-1/CD54 and C-type lectin/mannose (glucosamine)-rich C-type lectin receptor (CLR) interactions.
|
326 |
17073943

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.

|
Here, we analyze the phenotypic and functional outcomes of MBP-treated dendritic cells (DCs) and show that MBP induces DC activation and production of proinflammatory cytokines (interleukin-1beta [IL-1beta], IL-6, IL-8, tumor necrosis factor alpha, and IL-12p70) within 24 h and strongly increases Ikappabeta phosphorylation in treated cells.
|
330 |
17220311
|
Consistent with this hypothesis, MBP activated the TLR4-expressing cell line 293-hTLR4A but not control cultures to secrete IL-8.

Each gene encoded a cell surface chimeric protein made up of extracellular single-chain immunoglobulin anti-erbB2 linked to an intracellular TLR-signaling component composed of either myeloid differentiation factor 88, interleukin-1 receptor-associated kinase-1 (IRAK-1) or the cytoplasmic domain of TLR4.

356 |
17629597
|
We recently described that vaccination of mice with a glutathione S transferase fusion protein representing amino acids 261-500 of the Amastigote Surface Protein-2 efficiently cross-primed protective CD8+ T cells against a lethal challenge with the human protozoan parasite Trypanosoma cruzi.

357 |
17629597

Subsequently, we studied the importance of TLR9 agonist CpG ODN 1826, TLR4 and CD4+ T cells for the generation of these protective CD8+ T cells.
|
358 |
17629597
|
We found that: (i) the TLR9 agonist CpG ODN 1826 improved the efficiency of protective immunity; (ii) TLR4 is not relevant for priming of specific CD8+ T cells; (iii) CD4+ T cells are critical for priming of memory/protective CD8+ T cells.

In addition, we have shown that CD8+, natural killer, and CD4+ cells are important for protective antitumor effect generated by irradiated tumor cell-based vaccines expressing Hsp70.
|
366 |
17942939

To enhance DC-based vaccines, we used the combination of a synthetic ligand-inducible CD40 receptor (iCD40) along with Toll-like receptor-4 (TLR-4) ligation in human monocyte-derived DCs.
|
371 |
17974997
|
The iCD40 receptor permits targeted, reversible activation of CD40 in vivo, potentially bypassing the essential role of CD4(+) T cells for activation of DCs.
|
372 |
17974997
|
Whereas neither iCD40 nor TLR-4 signaling alone led to high levels of interleukin (IL)-12p70 and IL-6, using iCD40 in combination with lipopolysaccharide (LPS) or monophosphoryl lipid A led to strongly synergistic production of both.

An intranasal vaccine composed of Toll-like receptor 2 (TLR2) ligand Neisseria meningitidis outer membrane proteins and Toll-like receptor 4 (TLR4) ligand Shigella flexneri lipopolysaccharide (LPS) (Protollin) and enriched respiratory syncytial virus (RSV) proteins (eRSV) has been demonstrated to promote balanced Th1/Th2 responses without eosinophil recruitment and to protect against challenge in mouse models.
|
478 |
19013492
|
We used TLR2, TLR4 and myeloid differentiation factor 88 (MyD88) knock-out (-/-) mice to investigate the roles of these signalling pathways on immunogenicity, protection and pulmonary infiltrates following RSV immunization and challenge.
|
479 |

The upregulation of early signalling molecules IFN-beta, TNFalpha, CD40 and CD86 were studied in splenocytes isolated from naïve TLR2, TLR4 and MyD88-/- mice following stimulation with vaccine components.
|
482 |
19013492
|
Splenocytes from TLR4-/- mice displayed reduced IFN-beta while those of MyD88-/- mice elicited less TNFalpha and lower expression of CD40 and CD86 on CD11c+ cells.
|
483 |
19013492

The upregulation of early signalling molecules IFN-beta, TNFalpha, CD40 and CD86 were studied in splenocytes isolated from naïve TLR2, TLR4 and MyD88-/- mice following stimulation with vaccine components.
|
490 |
19013492
|
Splenocytes from TLR4-/- mice displayed reduced IFN-beta while those of MyD88-/- mice elicited less TNFalpha and lower expression of CD40 and CD86 on CD11c+ cells.
|
491 |
19013492
|
Together, our results suggest that optimal immunogenicity and protection against RSV without risk of enhanced pulmonary inflammation requires intact TLR4/MyD88-dependent signalling.

Considering the importance of CD14 - TLR2/TLR4 interactions in macrophage signalling, we determined the polymorphism of TLR2 and TLR4 genes as well as macrophage expression of TLR2 for the volunteers with and without skin reactivity to PPD.
|
533 |
19056540
|
A significant increase in CD14 density was observed on macrophages stimulated with PPD and LPS but not with live BCG bacilli.

It has been known that ornithine decarboxylase (ODC) induced by the binding of c-Myc to odc gene is closely linked to cell death.
|
544 |
19412607
|
ODC expression was increased by bacteria or LPS and repressed by inhibitors against mitogen-activated protein kinases (MAPKs) in Toll-like receptor 4 (TLR4) signaling pathway.
|
545 |
19412607
|
The cell death induced by bacteria was significantly decreased after treatment of CCD or c-Myc inhibitor, indicating that cell death by S. typhimurium infection is related to c-Myc, but not ODC.

Bone marrow-derived mesenchymal stromal cells (MSC) possess an immune plasticity manifested by either an immunosuppressive or, when activated with IFN-gamma, an APC phenotype.
|
548 |
19494321
|
We observed that human MSC and macrophages expressed TLR3 and TLR4 at comparable levels and TLR-mediated activation of MSC resulted in the production of inflammatory mediators such as IL-1beta, IL-6, IL-8/CXCL8, and CCL5.
|
549 |
19494321
|
IFN-alpha or IFN-gamma priming up-regulated production of these inflammatory mediators and expression of IFNB, inducible NO synthase (iNOS), and TRAIL upon TLR activation in MSC and macrophages, but failed to induce IL-12 and TNF-alpha production in MSC.
|
550 |
19494321
|
In addition, IFN priming combined with TLR activation may increase immune responses induced by Ag-presenting MSC through presentation of Ag in an inflammatory context, a mechanism that could be applied in a cell-based vaccine.

|
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.
|
553 |
19540594
|
This activation process was absolutely dependent on TLR4 and CD14.
|
554 |
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.

In addition, the members of the TLR2 subfamily were found to be most strongly involved in the host response to C. perfringens challenge, although the expression of TLR4 and TLR7 was also upregulated in spleen tissues.
|
576 |
19776194
|
While the combination of TLR1.2, TLR2.1, and TLR15 appeared to play a major role in the splenic response, the expression of TLR2.2 and TLR1.1 was positively correlated to the expression of adaptor molecules MyD88, TRAF6, TRIF, and receptor interacting protein 1 in the ileal tissues, demonstrating a dynamic spatial and temporal innate host response to C. perfringens.

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.
|
599 |
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.
|
600 |
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.
|

20051250
|
Sheep PBMC stimulated with either CpG (TLR9 agonist) or RNA oligoribonucleotides ([ORNs], TLR7/8 agonist) exhibited significant IL-12 production, but only CpG induced IFNalpha, IgM and proliferative responses.
|
604 |
20051250

Sheep B cells constitutively expressed TLR7, TLR8 and TLR9 mRNA transcripts, suggesting a possible role of TLR cross-talk in the down-regulatory mechanisms.

Recently, we determined that the minor pulmonary surfactant phospholipid, palmitoyl-oleoyl-phosphatidylglycerol (POPG), could markedly attenuate inflammatory responses induced by lipopolysaccharide through direct interactions with the Toll-like receptor 4 (TLR4) interacting proteins CD14 and MD-2.

The following firm conclusions can be drawn: multiple TLRs activate innate immunity upon RSV infection; TLR4 can influence TLR2 expression, suggesting that optimal induction of multiple signaling pathways is required to elicit protective, rather than deleterious innate immune responses following infection; in mice, TLR4, TLR2/-6, and TLR7 have immune-stimulating properties, while TLR3 activation occurs later and appears to downregulate immune responses; in humans, polymorphism studies have demonstrated an important role for TLR4-signaling; and activation of TLR-signaling leads to antiviral cytokine production, such as TNF-a and IFNs.

|
The current studies used the Toll-like receptor 2 (TLR2) agonist palmitoyl(3)-cysteine-serine-lysine(4) (PAM) or the TLR4 agonist lipopolysaccharide (LPS) to stimulate human whole blood and determine whether postponing the addition of the GC dexamethasone (DEX) limits its ability to decrease cytokine production.
|
664 |
20445007
|
Twenty-four hours after stimulation, tumor necrosis factor (TNF), interleukin-1beta (IL-1beta), IL-6, and IL-8 levels were measured, in addition to the cytokine inhibitors IL-1 soluble receptor II (SRII), IL-1 receptor antagonist, and TNF SRII.

Optimal TLR9 signal converts tolerogenic CD4-8- DCs into immunogenic ones capable of stimulating antitumor immunity via activating CD4+ Th1/Th17 and NK cell responses.
|
669 |
20466823
|
We have demonstrated previously that CD4-8- DCs secreting TGF-beta stimulate CD4+ Tr1 cell responses.
|
670 |
20466823
|
Here, we have assessed whether TLR4 and TLR9 signaling through LPS and CpG stimulation can convert CD4-8- DC-induced tolerance.
|
671 |
20466823
|
CpG-treated, CD4-8- DCOVA-secreting IL-6/IL-15 induced IFN-gamma/IL-17-secreting/T-bet- and ROR-gammat-expressing CD4+ Th1/Th17, whereas LPS-treated CD4-8- DCOVA stimulated IFN-gamma-secreting/T-bet-expressing CD4+ Th1 responses.
|
672 |
20466823
|
CpG-treated, CD4-8- DCOVA-stimulated CD4+ Th1/Th17 cell responses and antitumor immunity were found to be reduced by using neutralizing anti-IL-6, IL-15, and NK1.1 antibodies in wild-type C57BL/6 mice, IL-15R-/- mice for immunization, or CD4-8- (IL-6-/-) DCOVA for immunization in C57BL/6 mice.
|
673 |
20466823
|
Interestingly, in vitro-generated CD4+ Th17 cells significantly enhanced LPS-treated, CD4-8- DCOVA-induced in vivo antitumor immunity via increasing CD8+ CTL responses (P<0.05), although they did not show any direct killing activity against tumor cells in vitro.
|
674 |
20466823
|
Taken together, our data demonstrate an effect of conversion of tolerogenic DCs into immunogenic ones capable of stimulating antitumor immunity via activating CD4+ Th1/Th17 and NK cell responses by optimal CpG signaling, which may advance current understanding of the importance of TLR9 signaling in a DC-based cancer vaccine.

|
ROS orchestrated T(H)2 responses by inducing oxidized lipids that triggered the induction of thymic stromal lymphopoietin (TSLP) by epithelial cells mediated by Toll-like receptor 4 (TLR4) and the adaptor protein TRIF; by suppressing production of the T(H)1-inducing molecules IL-12 and CD70 in lymph node DCs; and by inducing the DC-derived chemokine CCL7, which mediated recruitment of IL-4(+) basophils to the lymph node.

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.

LL-37 neutralized the pro-inflammatory activity of endotoxin-free CPS as assessed by TLR2 and TLR4-MD-2-dependent release of TNFα, IL-6 and IL-8 from human and murine macrophages.
|
720 |
21049021
|
LL-37 also inhibited the ability of meningococcal CPS to induce nitric oxide release, as well as TNFα and CXCL10 (IP-10) release from TLR4-sufficient and TLR4-deficient murine macrophages.
|
721 |
21049021
|
We conclude that the capacity of meningococcal CPS to activate macrophages via TLR2 and TLR4-MD-2 can be inhibited by the human cationic host defense peptide LL-37 and propose that this impacts CPS-based vaccine responses.

|
Using Toll-like receptor (TLR) and MyD88 gene knock-out (GKO) mice the effect of TLRs and MyD88 on virus replication, interferon (IFN)-β production, natural killer (NK) cell and CD8T cell responses were assessed following ectromelia virus (ECTV) and recombinant vaccinia virus (rVV) infection.
|
725 |
21173782
|
Results showed that TLR2(-/-), TLR4(-/-)and TLR7(-/-) mice survived ECTV infection whereas MyD88(-/-) and TLR9(-/-)mice, in contrast, were highly susceptible.
|
726 |
21173782
|
Next, following infection with rVV, MyD88(-/-) mice elicited reduced serum IFN-β, NK cell and CD8T cell responses compared with wild-type mice, whereas TLR9(-/-) mice showed elevated CD8T cell responses.
|
727 |
21173782
|
Interestingly, even though rVV co-expressing interleukin (IL)-2 enhanced NK cell activation in MyD88(-/-) mice, this was not associated with an antiviral effect, as observed in normal mice.
|
728 |
21173782
|
Surprisingly, co-infection with rVV IL-2/rVV IL-12, but not rVV IL-2/rVV IFN-β, restored the attenuated phenotype of rVV IL-2 in MyD88(-/-) mice indicating that the IL-2/IL-12 combination promotes antiviral responses.

Meningococcal CPS induced a dose-dependent release of cytokines (TNF-α, IL-6, IL-8, and CXCL10) and NO from human and murine macrophages, respectively.
|
730 |
21191086
|
CPS induced IL-8 release from HEK cells stably transfected with TLR2/6, TLR2, TLR2/CD14, and TLR4/MD-2/CD14 but not HEK cells alone. mAb to TLR2 but not an isotype control antibody blocked CPS-induced IL-8 release from HEK-TLR2/6-transfected cells.
|
731 |
21191086
|
A significant reduction in TNF-α and IL-8 release was seen when THP-1- and HEK-TLR4/MD-2-CD14- but not HEK-TLR2- or HEK-TLR2/6-transfected cells were stimulated with CPS in the presence of Eritoran (E5564), a lipid A antagonist that binds to MD-2, and a similar reduction in NO and TNF-α release was also seen in RAW 264.7 cells in the presence of Eritoran.
|
732 |
21191086
|
CD14 and LBP enhanced CPS bioactivity, and NF-κB was, as anticipated, the major signaling pathway.

Compared to the mice unvaccinated or vaccinated with empty plasmid, CD11c(+) cells at the dLN from naïve B6 mice expressed prominent IL-12 mRNA after the T.g.HSP70 gene vaccine.
|
750 |
21236236

Also, CD4(+) cells at the dLN from the mice expressed prominent interferon-γ, but not IL-4 or IL-17, mRNA at a maximum level at day 5 following vaccination.
|
751 |
21236236
|
This T.g.HSP70 gene vaccine-induced DC activation and Th1 polarization were also observed in TRIF-deficient mice, but not MyD88-deficient mice with B6 background indicating the involvement of TLR4/MyD88 signal transduction cascade in the vaccine effects with T.g.HSP70 gene.
|
752 |
21236236
|
The T.g.HSP70 gene vaccine (twice at a 2-week interval) has been shown to limit T. gondii loads in the mesenteric LN of WT, TLR2-deficient and TRIF-deficient mice, but neither TLR4-deficient nor MyD88-deficient mice, at an acute phase of toxoplasmosis.
|
753 |
21236236

HBHA induced DC maturation in a TLR4-dependent manner, elevating expression of the surface molecules CD40, CD80, and CD86, MHC classes I and II and the proinflammatory cytokines IL-6, IL-12, IL-1β, TNF-α, and CCR7, as well as stimulating the migratory capacity of DCs in vitro and in vivo.
|
768 |
21368092
|
Mechanistic investigations established that MyD88 and TRIF signaling pathways downstream of TLR4 mediated secretion of HBHA-induced proinflammatory cytokines.
|
769 |

The major alleles of coding SNPs in the TLR2 (rs3804100) and TLR4 (rs5030710) genes were associated with a dose-related increase (660 vs. 892 mIU/ml, p = 0.002) and a dose-related decrease (2,209 vs. 830 mIU/ml, p = 0.001) in measles-specific antibodies, respectively.
|
775 |
21424379
|
We observed an additional 12 associations (p < 0.01) between coding (nonsynonymous and synonymous) polymorphisms within the TLRs (TLR2, 7, and 8), IKBKE, TICAM1, NFKBIA, IRAK2, and KIAA1542 genes and variations in measles-specific IL-2, IL-6, IFN-α, IFN-γ, IFNλ-1, and TNF-α secretion levels.

Priming CD8+ T cells with dendritic cells matured using TLR4 and TLR7/8 ligands together enhances generation of CD8+ T cells retaining CD28.
|
778 |
21493800
|
Maturation of DCs with lipopolysaccharide (LPS; TLR4) concurrently with R848 (TLR7/8) induced a heterogeneous population of DCs that produced high levels of IL12 p70.
|
779 |
21493800
|
Compared with DCs matured with LPS or R848 alone, the DC population matured with both adjuvants primed CD8+ T-cell responses containing an increased proportion of antigen-specific T cells retaining CD28 expression.
|
780 |
21493800
|
Priming with a homogenous subpopulation of LPS/R848-matured DCs that were CD83(Hi)/CD80+/CD86+ reduced this CD28+ subpopulation and induced T cells with an effector cytokine signature, whereas priming with the less mature subpopulations of DCs resulted in minimal T-cell expansion.
|
781 |
21499439
|
The expression of CD1a, CD38, CD40, CD54, CD80, CD83, CD86, HLA-DR and CCR7 on URC-primed DC was enhanced.
|
782 |
21499439
|
The production of IL-12p70 by URC-primed DC was inhibited by the anti-Toll-like receptor 4 (TLR4) monoclonal antibody (mAb), but partially abolished by anti-TLR2 mAb. mRNA coding for TLR2 and TLR4 was expressed in URC-primed DC.
|
783 |
21499439
|
DC matured with URC had an intermediate migratory capacity towards CCL19 and CCL21.

|
Most of the TLR agonists induced TNFα, IL-1β, IL-6, and IL-10 in cord blood.
|
785 |
21533209
|
The greatest TNFα responses were observed for TLR4, -5, and -8 agonists, the highest being the thiazoloquinoline CLO75 (TLR7/8) that also uniquely induced cord blood IFNγ production.
|
786 |
21533209
|
TLR8 agonists also induced the greatest production of the Th1-polarizing cytokines TNFα and IFNγ throughout the first year of life, although the relative responses to the single TLR8 agonist and the combined TLR7/8 agonist changed with age.
|
787 |
21533209
|
In contrast, IL-1β, IL-6, and IL-10 responses to most agonists were robust at birth and remained stable through 12 months of age.

Signaling downstream of TLR4 is mediated by the adaptor proteins TRIF [Toll-interleukin-1 (IL-1) receptor (TIR) domain-containing adaptor-inducing interferon-β], which is required for adaptive immune outcomes, and MyD88 (myeloid differentiation marker 88), which is responsible for many proinflammatory effects.
|
789 |
21540455
|
According to the first model, MLA fails to induce maturation of the proinflammatory cytokine IL-1β because it fails to activate caspase-1, which is required for the conversion of pro-IL-1β into its bioactive form.
|
790 |
21540455
|
The second model suggests that MLA triggers unequal engagement of both of the signaling adaptor pathways of TLR4, such that signaling mediated by TRIF is largely intact, whereas signaling mediated by MyD88 is incomplete.
|
791 |
21540455
|
We show that the TRIF-biased signaling that is characteristic of low-toxicity MLA explains its failure to activate caspase-1.
|
792 |
21540455
|
Defective induction of NLRP3, which depends on MyD88, led to decreased assembly of components of the IL-1β-activating inflammasome required for the activation of preformed, inactive procaspase-1.
|
793 |
21540455
|
In addition, we elucidated the contributions of MyD88 and TRIF to priming of the NLRP3 inflammasome and demonstrated that TRIF-biased TLR4 activation by MLA was responsible for the defective production of mature IL-1β.

Increasing numbers of endogenous danger signals of host origin are being identified including, for example, uric acid and cholesterol crystals, high mobility group box1 (HMGB1) protein, oxidized LDL, vesicans, heat shock proteins (HSPs) and self DNA.
|
807 |
21560483
|
Moreover, some PRRs (e.g., TLR2,TLR4 and NLRP3) and atypical PRRs can recognize both PAMPs and DAMPs, either as single entities or after forming complexes (e.g., immune complexes, or DNA- HMGB1 and DNA-LL37 complexes), so there must be a mechanism to selectively depress or alleviate the inflammatory response to DAMPs, while leaving that of PAMPs intact.
|
808 |
21560483
|
For example, CD24 reacting with HMGB1 and HSPs has been implicated to function as negative regulator for RAGE.

TLR4 activation by bacterial lipopolysaccharide (LPS) is achieved by the coordinate and sequential action of three other proteins, LBP, CD14 and MD-2 receptors, that bind lipopolysaccharide (LPS) and present it to TLR4 by forming the activated (TLR4-MD-2-LPS)(2) complex.
|

|
To determine what type of adjuvant can better enhance the immunogenicity of a Chlamydia vaccine, we formulated the recombinant major outer membrane protein (Ct-rMOMP) with several ligands for Toll-like receptors (TLR) and the nucleotide-binding oligomerization domain (NOD) including Pam(2)CSK(4) (TLR2/TLR6), Poly (I:C) (TLR3), monophosphoryl lipid A (TLR4), flagellin (TLR5), imiquimod R837 (TLR7), imidazoquinoline R848 (TRL7/8), CpG-1826 (TLR9), M-Tri-(DAP) (NOD1/NOD2) and muramyldipeptide (NOD2).
|
817 |
21742006
|
As determined by the IgG2a/IgG1 ratio in the sera, mice immunized with Ct-rMOMP+Pam(2)CSK(4) showed a strong Th2 biased humoral immune response.
|
818 |
21742006
|
In addition, based on changes in body weight, weight of the lungs and number of IFU recovered from the lungs, the mice immunized with Ct-rMOMP+Pam(2)CSK(4), were better protected against the i.n. challenge than any group of mice immunized with Ct-rMOMP and the other adjuvants.
|
819 |
21742006
|
In conclusion, Pam(2)CSK(4) should be evaluated as a candidate adjuvant for a C. trachomatis vaccine.

A Salmonella vector vaccine expressing the saliva-binding region (SBR) of the adhesin AgI/II of Streptococcus mutans has been shown to induce a mixed Th1/Th2 anti-SBR immune response in mice and to require Toll-like receptor 2 (TLR2), TLR4, and MyD88 signaling for the induction of mucosal anti-SBR antibody responses.
|
821 |
21746857
|
Bone marrow-derived DC from wild-type and TLR2, TLR4, and MyD88 knockout mice were stimulated with Salmonella vector BRD509, the SBR-expressing Salmonella vector vaccine BRD509(pSBRT7), or SBR protein, and the DC responses to different stimuli were compared by assessing costimulatory molecule expression, cytokine production, and signaling pathways.
|
822 |
21746857
|
BRD509(pSBRT7) and BRD509 induced upregulation of CD80, CD86, CD40, and major histocompatibility complex class II (MHC II) expression.
|
823 |
21746857
|
The low IL-12p40 and high IL-6 cytokine profile expressed by BRD509(pSBRT7)-stimulated DC may represent a shift toward a Th2 response, as suggested by the increased expression in Jagged-1.

We show here that RVFHbαP exerts an anti-inflammatory activity in hVECs, as suggested by the prevention of LPS-induced production of extracellular (supernatant) and intracellular (lysate) levels of cytokines (interleukin 6 [IL-6] and IL-1α) and chemokines (IL-8 and monocyte chemoattractant protein 1 [MCP-1]).
|

21865417
|
The demonstration of Toll-like receptor 4 (TLR4) and NF-κB expression in hVECs and the observations of RVFHbαP suppression of human β-defensin-1 (hBD1) mRNA expression further support the hypothesis of a genomic activity of RVFHbαP.

Use of Lactobacillus species to combat UTI is now giving modern concept of modern genitourinary vaccine with the facts that it not only maintains low pH of the genital area, produces hydrogen peroxide and hinders the growth of E. coli but also activates Toll-like receptor-2 (TLR2), which produces interleukin-10 (IL-10) and myeloid differentiation factor 88 (MyD88).

In a previous work, we found that the extra domain A from fibronectin EDA (an endogenous ligand for TLR4) can favour antigen delivery to DC and induce their maturation.
|
837 |
22387222
|
Given the potential of anaphylatoxins to cause inflammation and activation of myeloid cells, we hypothesized that a fusion protein between EDA, and anaphylatoxins C3a, C4a or C5a together with an antigen might improve the immunogenicity of the antigen.

We demonstrated that direct exposure of porcine APCs to L. jensenii in the absence of inflammatory signals increased expression of interleukin-10 (IL-10) and transforming growth factor β in CD172a(+) APCs and caused them to display tolerogenic properties.
|
882 |
22573738

|
917 |
22908333
|
Inhibition was dependent on TLR4 and was associated with the induction of ICOS in cells of the nasal mucosa and on both CD4+Foxp3+ and CD4+Foxp3- T cells of the draining lymph nodes (LNs), as well as their recruitment to the lungs.

Using MOMP formed in pure protein micelles (proteosomes), we show the induction of TLR2-dependent interleukin-8 (IL-8) and IL-6 secretion in vitro, the involvement of TLR1 as a TLR2 coreceptor, and the activation of both NF-κB and mitogen-activated protein (MAP) kinase intracellular pathways.

One is the plasmacytoid DC (pDC), which expresses nucleic acid sensing receptors TLR7 and TLR9 and secretes large amounts of type I interferons in response to TLR7/9 signaling.
|

|
This DC subset expresses lipid sensors, TLR2 and TLR4, and nucleic acid sensors, TLR3, TLR9 and TLR13 and is specialized for antigen crosspresentation.

Whereas wild-type Escherichia coli LPS provokes strong inflammatory MyD88 (myeloid differentiation primary response gene 88)-mediated TLR4 signaling, MPL preferentially induces less inflammatory TRIF (TIR-domain-containing adaptor-inducing IFN-β)-mediated responses.

Surprisingly, inhibitory interactions between TLR4 and TLR2, TLR4 and Dectin-1, and TLR2 and TLR9 as well as TLR3 and TLR2 were observed.
|
945 |
23432484

We also found that OmpS1 is a Toll-like receptor 4 (TLR4) agonist, whereas OmpS2 is a TLR2 and TLR4 agonist.
|
946 |
23432484
|
Both porins induced the production of tumour necrosis factor and interleukin-6, and OmpS2 was also able to induce interleukin-10 production.

TRIF is required for TLR4 mediated adjuvant effects on T cell clonal expansion.
|
948 |

Activation of TLR4 by its ligands is mediated by engagement of the adapter proteins MyD88 (myeloid differentiation factor 88) and TRIF (Toll-interleukin 1 receptor domain-containing adapter inducing interferon-beta).
|
949 |

|
In this study, we investigated the T cell priming events that are regulated specifically by the TRIF signaling branch of TLR4.

We found that TRIF deficiency prevented the TLR4 agonist lipid A from enhancing T cell proliferation and survival in an adoptive transfer model of T cell priming.
|
952 |
23457630
|
Importantly, TRIF alone caused CD86 and CD40 upregulation on splenic DC, but both TRIF and MyD88 were required for CD80 upregulation.
|
953 |
23457630
|
The impairment of T cell adjuvant effects and defective DC maturation in TRIF (lps/lps) mice after TLR4 stimulation was mainly due to loss of type I IFN production, indicating that type I interferons are central to TLR4's adjuvant effects.

Combined TLR2- and TLR4-activated DC/tumor overcame immune-suppressive effect of TGF-β1 in comparison to those single activated or un-activated DC/tumor as demonstrated by: 1) up-regulation of MHC class II and CD86 expression on DC/tumor; 2) increased fusion efficiency; 3) increased production of fusions derived IL-12p70; 4) activation of CD4(+) and CD8(+) T cells that produce high levels of IFN-γ; 5) augmented induction of CTL activity specific for MUC1; and 6) superior efficacy in inhibiting CD4(+)CD25(+)Foxp3(+) T cell generation.

Reduced frequency of a CD14+ CD16+ monocyte subset with high Toll-like receptor 4 expression in cord blood compared to adult blood contributes to lipopolysaccharide hyporesponsiveness in newborns.
|
991 |
23595503
|
To better understand the mechanistic basis for this age-related difference in innate immunity, we compared tumor necrosis factor alpha (TNF-α) production by monocytes from cord blood (CB) and adult blood (AB) in response to LAM (lipoarabinomannan from Mycobacterium tuberculosis, a TLR2 ligand) and LPS (lipopolysaccharide from Escherichia coli, a TLR4 ligand).
|
992 |
23595503
|
LPS or LAM-induced TNF-α production was 5 to 18 times higher in AB than in CB monocytes, whereas interleukin-1α (IL-1α) stimulated similar levels of TNF-α in both groups, suggesting that decreased responses to LPS or LAM in CB are unlikely to be due to differences in the MyD88-dependent signaling pathway.
|
993 |
23595503
|
This impaired signaling was attributable, in part, to lower functional TLR4 expression, especially on CD14(+) CD16(+) monocytes, which are the primary cell subset for LPS-induced TNF-α production.
|
994 |
23595503
|
Importantly, the frequency of CD14(+) CD16(+) monocytes in CB was 2.5-fold lower than in AB (P < 0.01).
|
995 |
23595503
|
CB from Kenyan newborns sensitized to parasite antigens in utero had more CD14(+) CD16(+) monocytes (P = 0.02) and produced higher levels of TNF-α in response to LPS (P = 0.004) than CB from unsensitized Kenyan or North American newborns.
|
996 |
23595503
|
Thus, a reduced CD14(+) CD16(+) activated/differentiated monocyte subset and a correspondingly lower level of functional TLR4 on monocytes contributes to the relatively low TNF-α response to LPS observed in immunologically naive newborns compared to the response in adults.

1019 |
23595505

Genetic variants associated with severity of meningococcal disease, including the IgG Fc receptor (FCγRII)-A484T, interleukin-10 (IL-10)-A1082G, -C819T, and -C627A, IL-4-C589T, mannose binding lectin-2 (MBL2)-A/O, -H/L, -P/Q, and -X/Y, toll-like receptor 2 (TLR2)-G2408A, TLR4-A12874G and -C13174T, and TLR9-T1237C and -T1486C were determined by real-time PCR (RT-PCR) for 271 HIV-infected subjects (median, 17 years).
|
1020 |
23595505
|
These findings suggest that for HIV-infected youth, the initial antibody response to MCV4 is associated with variants in TLR2 and TLR4 while the long-term response is associated with genetic polymorphisms in TLR9 and FcγRIIa.

|
1027 |
23781340
|
Most notably, the upregulation of CD40 with LPS stimulation and CD86 with CpG stimulation was observed in in vitro cultures.
|
1028 |
23781340
|
Similarly, IFN-gamma coinjected with TLR ligands was able to promote DC activation in vivo, with DCs migrating from the site of immunization to the popliteal lymph nodes demonstrating increased expression of CD80 and CD86.

MyD88/Toll-like receptor 4 (TLR4) and TRIF/TLR4 signaling pathways showed equally decreased signaling with the LPS forms studied here as with endotoxic LPS or detoxified monophosphorylated lipid A (MPLA).
|
1030 |
23798540

Natural monophosphorylated LPS from mucosa-associated bacteria functions as a weak but effective adjuvant for specific immune responses, with preferential effects on antibody and CD4 T cell responses over CD8 T cell responses.

We previously reported that sepsis differentially represses transcription and translation of tumor necrosis factor alpha (TNF-α) and interleukin 1β (IL-1β) to reprogram sepsis inflammation.
|
1032 |
23825193
|
We showed that phosphorylation-dependent activation of p38 mitogen-activated protein kinase (MAPK) and translation disruption of TNF-α and IL-6 follow increased MAPK phosphatase 1 (MKP-1) expression and that MKP-1 knockdown rephosphorylates p38 and restores the capacity to translate TNF-α and IL-6 mRNAs.
|
1033 |
23825193
|
We also observed that the RNA-binding protein motif 4 (RBM4), a p38 MAPK target, accumulates in an unphosphorylated form in the cytosol in endotoxin-adapted cells, suggesting that dephosphorylated RBM4 may function as a translational repressor.
|
1034 |
23825193
|
Moreover, MKP-1 knockdown promotes RBM4 phosphorylation, blocks its transfer from the nucleus to the cytosol, and reverses translation repression.
|
1035 |
23825193
|
We also found that microRNA 146a (miR-146a) knockdown prevents and miR-146a transfection induces MKP-1 expression, which lead to increases or decreases in TNF-α and IL-6 translation, respectively.
|
1036 |
23825193
|
We conclude that a TLR4-, miR-146a-, p38 MAPK-, and MKP-1-dependent autoregulatory pathway regulates the translation of proinflammatory genes during the acute inflammatory response by spatially and temporally modifying the phosphorylation state of RBM4 translational repressor protein.

High-dose gp96 immunization elicited rapid and long-lasting protection of mice against concanavalin A (Con A)-and anti-CD137-induced liver injury, as evidenced by decreased alanine aminotransaminase (ALT) levels, hepatic necrosis, serum pro-inflammatory cytokines (IFN-γ, TNF-α, and IL-6), and number of IFN-γ (+) CD4(+) and IFN-γ (+) CD8(+) T cells in the spleen and liver.
|
1040 |
23874845
|
In contrast, CD4(+)CD25(+)Foxp3(+) Treg frequency and suppressive function were both increased, and the protective effect of gp96 could be generated by adoptive transfer of Treg cells from gp96-immunized mice.
|
1041 |
23874845
|
In vitro co-culture experiments demonstrated that gp96 stimulation enhanced Treg proliferation and suppressive function, and up-regulation of Foxp3, IL-10, and TGF-β1 induced by gp96 was dependent on TLR2- and TLR4-mediated NF-κB activation.

Nasal vaccination with attenuated Salmonella expressing VapA: TLR2 activation is not essential for protection against R. equi infection.
|
1045 |
23933366
|
We have previously demonstrated that oral immunisation with attenuated Salmonella enterica Typhimurium strain expressing the antigen VapA (STM VapA+) induces specific and long-term humoral and cellular immunity against R. equi.
|
1046 |
23933366

It was shown that VapA activates Toll-like receptor 2 (TLR2) on macrophages by establishing an interaction that ultimately favours immunity against R. equi infection.

|
The purpose of this study was to evaluate the immune response triggered by nasal immunisation with STM VapA+ and to determine whether TLR2 supports the vaccine effect.
|
1048 |
23933366
|
Nasal vaccination with STM VapA+ has also induced protection in Tlr2(-/-) mice and mice with non-functional TLR4.
|
1049 |
23933366
|
When similar experimental procedures were performed in TLR2 knockout mice, an increase in CD4(+) T cells with memory phenotype was not observed.
|
1050 |
23933366
|
Consequently, we conclude that nasal vaccination with attenuated Salmonella expressing the R. equi virulence factor VapA confers long-lasting protection against experimental rhodoccocosis and that TLR2 engagement was not crucial to induce this protection but may be required for a long-term immune response.

Toll-like receptor 3-mediated necrosis via TRIF, RIP3, and MLKL.
|
1054 |
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.
|
1055 |
24019532
|
In addition, TLR3 drives caspase 8-regulated programmed cell death pathways reminiscent of TNF family death receptor signaling.
|
1056 |
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.
|
1057 |
24019532
|
TLR3 or TLR4 directly activates programmed necrosis through a RIP homotypic interaction motif-dependent association of TRIF with RIP3 kinase (also called RIPK3).
|
1058 |
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.
|
1059 |
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.
|
1060 |
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.

Therefore, since WE-CN did not induce maturation of DCs generated from mice with mutated TLR-4 or TLR-2, suggesting that TLR4 and TLR2 might function as membrane receptors for WE-CN.
|
1070 |
24058377
|
Moreover, the mechanism of action of WE-CN may be mediated by increased phosphorylation of ERK, p38, and JNK mitogen-activated protein kinase (MAPK) and increased NF- κ B p65 activity, which are important signaling molecules downstream of TLR-4 and TLR-2.
|
1071 |
24058377

Finally, coimmunization of mice with WE-CN and a HER-2/neu DNA vaccine induced a HER-2/neu-specific Th1 response that resulted in significant inhibition of HER-2/neu overexpressing mouse bladder tumor (MBT-2) growth.

Urease, BabA and SabA in the adhesion-step, PGN and LPS in the immune evasion-step, and CagA, VacA and Tipα in the mucosal damage-step were documented to play an important role in step-specific pathogenicity of H. pylori infection.
|
1077 |
24076409
|
There is evidence further supporting a role of potentially functional polymorphisms of host genes directly responding to these pathogenic step-specific virulence factors in the susceptibility of gastric carcinogenesis, especially for urease-interacting HLA class II genes, BabA-interacting MUC1, PGN-interacting NOD1, LPS-interacting TLR4, and CagA-interacting PTPN11 and CDH1.

The levels of Toll-like receptor 4 (TLR4) and proinflammatory cytokines, including interleukin-1β (IL-1β) and IL-6, increased following OMV infection.

|
Colonization decreased frequencies of toll-like receptors (TLR) 2 and TLR4 expressing MNCs from vaccinated pigs (Pro+Vac) pre-challenge and increased frequencies of TLR3 expressing MNCs from Pro pigs post-challenge, suggesting that probiotics likely exert anti-inflammatory (TLR2 and 4 down-regulation) and antiviral (TLR3 up-regulation by HRV dsRNA) actions via TLR signaling.

Systemic inhibition of TLR9, but not TLR4, delayed tumor recurrence in mouse models of B16 melanoma, MB49 bladder cancer, and CT26 colon cancer after localized high-dose tumor irradiation.
|
1081 |
24154870
|
The tumorigenic effects of TLR9 depended on MyD88/NF-κB-mediated upregulation of interleukin (IL)-6 expression, which in turn resulted in downstream activation of Jak/STAT3 signaling in myeloid cells.
|
1082 |
24154870
|
In comparing global gene expression in wild-type, TLR9-, or STAT3-deficient myeloid cells derived from irradiated tumors, we identified a unique set of TLR9/STAT3-regulated genes involved in tumor-promoting inflammation and revascularization.

Human T-cell leukemia/lymphoma virus type 1 p30, but not p12/p8, counteracts toll-like receptor 3 (TLR3) and TLR4 signaling in human monocytes and dendritic cells.
|
1086 |
24155397
|
We used a human monocytic cell line, THP-1, and dendritic cells to study the mechanism of p30 and p12/p8 requirements in these cell types. p30 inhibited the expression of interferon (IFN)-responsive genes (ISG) following stimulation by lipopolysaccharide (LPS) of Toll-like receptor 4 (TLR4) and by poly(I·C) of TLR3 but not of TLR7/8 with imiquimod.
|
1087 |
24155397
|
HTLV-1 infection of monocytes inhibited TLR3- and TLR4-induced ISG expression by 50 to 90% depending on the genes, whereas the isogenic clone p30 knockout virus was less effective at inhibiting TLR3 and TRL4 signaling and displayed lower infectivity.
|
1088 |

24244265
|
We have previously demonstrated that vaccination with dendritic cells activated with the TLR-4 ligand LPS and IFN-γ promotes an antigen-specific anti-tumor response that prevents tumor recurrence.
|
1103 |
24244265
|
The effect is therefore mediated by a soluble factor but was independent of both IL-6 and IL-12.
|
1104 |
24244265
|
IFN-γ production was associated with upregulation of the Th1 transcriptional regulator T-bet, and a significant fraction of IFN-γ-producing regulators coexpressed T-bet and FoxP3.
|
1105 |
24244265
|
While the effects of the LPS-activated dendritic cell on responder cell proliferation were IL-12 independent, upregulation of T-bet was inhibited by a neutralizing anti-IL-12 antibody.

Here, we found that colorectal cancer (CRC) cells treated with oxaliplatin (OXA) and/or 5-fluorouracil (5-Fu) released high levels of high-mobility group box 1 (HMGB1) and heat shock protein 70 (HSP70).
|
1110 |
24362470
|
After OXA/5-Fu therapy, the sera of CRC patients also exhibited increased levels of HMGB1 and HSP70, both of which are well-known DAMPs.
|
1111 |
24362470
|
The supernatants of dying CRC cells treated with OXA/5-Fu promoted mouse and human DC maturation, with upregulation of HLA-DR, CD80 and CD86 expression and enhancement of IL-1β, TNF-α, MIP-1α, MIP-1β, RANTES and IP-10 production.
|
1112 |
24362470
|
Vaccines composed of DCs pulsed with the supernatants of chemically stressed CRC cells induced a more significant IFN-γ-producing Th1 response both in vitro and in vivo.
|
1113 |

Furthermore, pulsing with the supernatants of chemically stressed CRC cells did not efficiently induce an IFN-γ-producing Th1 response in TLR4-deficient DCs.

Many studies have reported genetic associations between severe RSV bronchiolitis and SNPs in genes within plausible biological pathways, such as in innate host defense genes (SPA, SPD, TLR4, and VDR), cytokine or chemokine response genes (CCR5, IFN, IL6, IL10, TGFB1), and altered Th1/Th2 immune responses (IL4, IL13).

It was observed that PA-MSHA activated PMSM towards a classical activation phenotype via a toll-like receptor4/9-dependent mechanism, which increased interleukin-12 levels and promoted the expression of co-stimulatory and antigen-presenting molecules like CD80, CD86, and MHC-II (P < 0.05).

We tested whether a Virulence Associated Protein A (VapA)/CpG vaccine against R. equi would impact the production of IL-10, IFN-γ and TNF-α in lung tissue and fluid samples, alter expression of TLR2 and TLR4 and alter their association with the lipid rafts in broncho-alveolar lavage (BAL) cells.

Nasal immunization with NE-based vaccine showed that the TLR2, TLR4, and MyD88 pathways and IL-12 and IL-12Rβ1 expression are not required for an Ab response, but they are essential for the induction of balanced Th-1 polarization and Th-17 cellular immunity.

Further, upon immunization with NE, adjuvant mice deficient in the CD86 receptor had normal Ab responses but significantly reduced Th-1 cellular responses, whereas animals deficient in both CD80 and CD86 or lacking CD40 failed to produce either humoral or cellular immunity.
|
1142 |

The enhanced IgA production by b240 was attenuated by neutralizing IL-6, a potent IgA-enhancing cytokine. b240 stimulated DCs to produce an elevated amount of IL-6 in a Toll-like receptor (TLR) 2-, but not TLR4- or TLR9-dependent manner.
|
1155 |
24632732
|
Finally, we demonstrated that TLR2-mediated IL-6 production from PP DCs in response to b240 activated B cells to produce a large amount of IgA in a DC-B cell co-culture system.

3-deoxy-D-manno-oct-2-ulosonic acid (Kdo)₂-lipid A is the conserved structure domain of lipopolysaccharide found in most Gram-negative bacteria, and it is believed to stimulate the innate immune system through the TLR4/MD2 complex.

However, ZBTB20-deficient plasma cells expressed reduced levels of MCL1 relative to wild-type controls, and transgenic expression of BCL2 increased serum antibody titers.
|
1158 |
24711582
|
Strikingly, adjuvants that activate TLR2 and TLR4 restored long-term antibody production in ZBTB20-deficient chimeras through the induction of compensatory survival programs in plasma cells.

The rapid killing of macrophages induced by Y. pestis, dependent upon type III secretion system effector Yersinia outer protein J (YopJ), is minimally affected by the absence of caspase-1, caspase-11, Fas ligand, and TNF.
|
1166 |
24799678
|
Here we provide genetic evidence for a receptor-interacting protein (RIP) kinase-caspase-8-dependent macrophage apoptotic death pathway after infection with Y. pestis, influenced by Toll-like receptor 4-TIR-domain-containing adapter-inducing interferon-β (TLR4-TRIF).
|
1167 |
24799678
|
Interestingly, macrophages lacking either RIP1, or caspase-8 and RIP3, also had reduced infection-induced production of IL-1β, IL-18, TNF, and IL-6; impaired activation of the transcription factor NF-κB; and greatly compromised caspase-1 processing.
|
1168 |
24799678
|
Cleavage of the proform of caspase-1 is associated with triggering inflammasome activity, which leads to the maturation of IL-1β and IL-18, cytokines important to host responses against Y. pestis and many other infectious agents.
|
1169 |
24799678
|
Our results identify a RIP1-caspase-8/RIP3-dependent caspase-1 activation pathway after Y. pestis challenge.
|
1170 |
24799678
|
Mice defective in caspase-8 and RIP3 were also highly susceptible to infection and displayed reduced proinflammatory cytokines and myeloid cell death.
|
1171 |
24799678
|
We propose that caspase-8 and the RIP kinases are key regulators of macrophage cell death, NF-κB and inflammasome activation, and host resistance after Y. pestis infection.

We explored the changes in the expression of TLR2, TLR4 and the concentration of acute inflammatory cytokines, such as IL-2, IL-8, IL-12 and IFN-γ in Bama miniature pigs subjected to 21 consecutive days of heat stress, both in vitro and in vivo models.
|
1204 |
24912383
|
The results showed that heat stress induced the upregulation of cortisol in the plasma of pigs (P<0.05); TLR4 mRNA was elevated, but IL-2 was reduced in peripheral blood mononuclear cells (PBMC, P<0.05).
|
1205 |

As the TLR4 activity of natural TLR4 ligands (lipopolysaccharide, LPS and its biologically active part, the lipid A) depends on both the structure of endotoxin aggregates in solution and on single-molecule interaction with MD-2 and CD14 receptors, the rational design of TLR4 modulators should in principle take into account both these factors.

|
The TB10.4 antigen of Mycobacterium bovis/Mycobacterium tuberculosis induces a strong Th1 CD4+ T-cell response.
|
1228 |
25019567
|
Here, as stimulated RAW264.7 cells with recombinant TB10.4 (rTB10.4), derived from M. bovis, increased TNF-α, IL-6 and IL-12 p40 secretin in a dose-dependent manner.
|
1229 |
25019567
|
Blocking assays showed that TLR2-, but not TLR4-neutralizing antibody reduced expression of TNF-α, IL-6 and IL-12 p40 in RAW264.7 cells. rTB10.4 stimulation activated p38 kinase (p38) and extracellular-regulated kinase (ERK) was TLR2-dependent, whereas inhibition of p38 and ERK activity significantly reduced TNF-α, IL-6 and IL-12 p40 production.
|
1230 |
25019567
|
Furthermore, rTB10.4 stimulation of RAW264.7 cells resulted in TLR2-mediated activation of NF-κB and induced translocation of NF-κB p65 from the cytoplasm to the nucleus via IκBα degradation. rTB10.4-induced TNF-α, IL-6 and IL-12 p40 release was attenuated by the specific IκB phosphorylation inhibitor, BAY 11-7082.
|
1231 |
25019567
|
These findings indicate that the M. bovis-derived rTB10.4 induced production of TNF-α, IL-6 and IL-12 p40 involves p38, ERK and NF-κB via the TLR2 pathway.

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.
|
1262 |
25114104
|
Alongside increased parasite expulsion, MyD88-deficient mice showed heightened IL-4 and IL-17A production from mesenteric lymph node CD4(+) cells.
|
1263 |
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.
|
1264 |
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.
|
1265 |
25114104
|
Like IL-1R1(-/-) and MyD88(-/-) mice, animals lacking signaling through the type 1 IFN receptor (i.e., IFNAR1(-/-)) also developed intestinal granulomas.
|
1266 |
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.

Significant associations were also found between IL10RB (rs2284552; measles study p value 0.006, rubella study p value 0.00008) and IL12B (rs2546893; measles study p value 0.005, rubella study p value 0.03) gene polymorphisms and variations in both measles- and rubella virus-specific IL-6 responses.
|
1270 |
25139337
|
We also identified associations between individual SNPs in the IFNAR2 and TLR4 genes that were associated with IFN-γ secretion for both measles and rubella vaccine-specific immune responses.
|
1271 |
25139337
|
Single-nucleotide polymorphisms (SNPs) in candidate immune response genes were evaluated for associations with measles- and rubella-specific neutralizing antibodies, interferon (IFN)-γ, and interleukin (IL)-6 secretion in two separate association analyses in a cohort of healthy immunized subjects.
|
1272 |
25139337
|
We identified six SNP associations shared between the measles-specific and rubella-specific immune responses, specifically neutralizing antibody titers (DDX58), secreted IL-6 (IL10RB, IL12B), and secreted IFN-γ (IFNAR2, TLR4).
|
1273 |
25139337

The TIR-domain containing adaptor TRAM is required for TLR7 mediated RANTES production.
|
1276 |
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.
|
1277 |
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.
|
1278 |
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.
|
1279 |
25211222
|
Additionally, TRAM-G2A dose-dependently inhibited TLR7 mediated activation of CCL5, IFNβ and IFNα reporter genes.
|
1280 |
25211222
|
TLR7-mediated phosphorylation and nuclear translocation of IRF3 was impaired in TRAM(-/-) cells.
|
1281 |
25211222
|
Finally, co-immunoprecipitation studies indicated that TRAM physically interacts with MyD88 upon TLR7 stimulation, but not under basal conditions.
|
1282 |
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.

Among the TLR family, TLR1, TLR2, TLR4, and TLR9 and their down-stream signaling proteins play critical roles in the initiation of the immune response in the pathogenesis of TB.
|
1286 |
25312698
|
The inflammasome pathway is associated with the coordinated release of cytokines such as IL-1β and IL-18 which also play a role in the pathogenesis of TB.

A mouse immunogenicity study was conducted using a stable oil-in-water emulsion (SE) of CS/D in combination with the Toll-Like Receptor 4 (TLR4) agonist Glucopyranosyl Lipid A (GLA/SE), or one of two TLR7/8 agonists: R848 (un-conjugated) or 3M-051 (covalently conjugated).

Although incubation with high concentrations of these 3 strains resulted in significant activation of the MM6 cells, it was found to occur mainly through interaction with TLR2 and not through TLR4.

1294 |
25389373

Signaling by Toll-like receptor 4 (TLR4) is mediated by either of two adaptor proteins: myeloid differentiation marker 88 (MyD88) or Toll-interleukin-1 (IL-1) receptor (TIR) domain-containing adaptor inducing interferon-β (TRIF).
|
1295 |
25389373
|
Whereas MyD88-mediated signaling leads to proinflammatory responses, TRIF-mediated signaling leads to less toxic immunostimulatory responses that are beneficial in boosting vaccine responses.
|
1296 |
25389373
|
The hypothesis that monophosphorylated lipid A structures act as TRIF-biased agonists of TLR4 offered a potential mechanism to explain their clinical value as vaccine adjuvants, but studies of TRIF-biased agonists have been contradictory.
|
1297 |
25389373
|
In experiments with mouse dendritic cells, we found that irrespective of the agonist used, TLR4 functioned as a TRIF-biased signaling system through a mechanism that depended on the autocrine and paracrine effects of type I interferons.
|
1298 |
25389373
|
The TLR4 agonist synthetic lipid A induced expression of TRIF-dependent genes at lower concentrations than were necessary to induce the expression of genes that depend on MyD88-mediated signaling.

25389373

These data may explain how high-potency TLR4 agonists can act as clinically useful vaccine adjuvants by selectively activating TRIF-dependent signaling events required for immunostimulation, without or only weakly activating potentially harmful MyD88-dependent inflammatory responses.

For protein-based vaccines, the main biological barrier to overcome is the default MHC class-II-pathway, with activation of CD4 T cells rather than CD8 T cells.
|
1336 |
25482339
|
The latter requires antigens to access the cytosol and MHC class I antigen presentation.
|
1337 |
25482339
|
This "photochemical internalisation" resulted in activation, proliferation, and IFN-γ production of cytotoxic CD8 T cells, which suppressed tumour growth by infiltrating CD8 T cells and caspase-3-dependent apoptosis.
|
1338 |
25482339
|
The process was independent of MHC class II, MyD88, and TLR4 signalling, but dependent on trypsin- and caspase-like proteasome activity and partly also on chloroquine.

Lipopolysaccharide (LPS) and resiquimod (R-848) are TLR agonists that are recognized by TLR4 and TLR7, respectively.
|
1340 |

LPS and R-848 synergistically up-regulated the transcripts of interferon-β (IFN-β), IFN-γ, IL-4 and IL-1β as compared to the individual response (P<0.05).

B cell TLR1/2, TLR4, TLR7 and TLR9 interact in induction of class switch DNA recombination: modulation by BCR and CD40, and relevance to T-independent antibody responses.
|
1342 |
25536171
|
Here, we have addressed cross-regulation between two different TLRs or between a TLR and CD40 in CSR induction by using a B cell stimulation system involving lipopolysaccharides (LPS).
|
1343 |
25536171
|
Consistent with the requirement for dual TLR and BCR engagement in CSR induction, LPS, which engages TLR4 through its lipid A moiety, triggered cytosolic Ca2+ flux in B cells through its BCR-engaging polysaccharidic moiety.
|
1344 |
25536171
|
In the presence of BCR crosslinking, LPS synergized with a TLR1/2 ligand (Pam3CSK4) in CSR induction, but much less efficiently with a TLR7 (R-848) or TLR9 (CpG) ligand.
|
1345 |
25536171
|
In the absence of BCR crosslinking, R-848 and CpG, which per se induced marginal CSR, virtually abrogated CSR to IgG1, IgG2a, IgG2b, IgG3 and/or IgA, as induced by LPS or CD154 (CD40 ligand) plus IL-4, IFN-γ or TGF-β, and reduced secretion of class-switched Igs, without affecting B cell proliferation or IgM expression.
|
1346 |
25536171
|
The CSR inhibition by TLR9 was associated with the reduction in AID expression and/or IgH germline IH-S-CH transcription, and required co-stimulation of B cells by CpG with LPS or CD154.
|
1347 |
25536171
|
Unexpectedly, B cells also failed to undergo CSR or plasma cell differentiation when co-stimulated by LPS and CD154.

Overall, by addressing the interaction of TLR1/2, TLR4, TLR7 and TLR9 in the induction of CSR and modulation of TLR-dependent CSR by BCR and CD40, our study suggests the complexity of how different stimuli cross-regulate an important B cell differentiation process and an important role of TLRs in inducing effective T-independent antibody responses to microbial pathogens, allergens and vaccines.

Thus, LREL-induced increases in the expression levels of several cell surface marker proteins, production of inflammatory cytokines IL-12p40 and TNF-α, and activation and nuclear translocation of transcription factors, as was observed in the WT DCs, were completely abrogated in DCs derived from the TLR4(-/-) mice but not in DCs derived from the TLR2(-/-), TLR7(-/-), and TLR9(-/-) mice.

The MYD88-dependent pathway involves early-phase activation of nuclear factor of kappa light polypeptide gene enhancer in B-cells 1 (NF-κB1) and all the TLRs, except TLR3, have been shown to activate this pathway.

Furthermore, we demonstrated that TLR2 and TLR4 are required for the stimulatory activity of AC hmwPSs on DCs.
|
1371 |

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.
|
1375 |
25805409

RpfE induces DC maturation by increasing expression of surface molecules and the production of IL-6, IL-1β, IL-23p19, IL-12p70, and TNF-α but not IL-10.
|
1378 |
25907170

RpfE-treated DCs effectively caused naïve CD4(+) T cells to secrete IFN-γ, IL-2, and IL-17A, which resulted in reciprocal expansions of the Th1 and Th17 cell response along with activation of T-bet and RORγt but not GATA-3.

In contrast, CVPS downregulated TGF-β mRNA expression and the frequency of CD4(+)CD25(+)Foxp3(+) Treg cells.
|
1383 |
25934108
|
Taken together, these results indicate that administering CVPS as an adjuvant enhances both cellular and humoral immune responses via the TLR-2 and TLR-4 signalling pathways, thereby promoting DC maturation and suppressing TGF-β expression and Treg frequency.

In this study, we explored the underlying mechanisms concerning the interaction between Coa-ASC16 and the immune system and we found that the whole inflammatory response elicited by Coa-ASC16 (leukocyte recruitment and IL-1β, IL-6 and IL-12 production) was dependent on the MyD88 protein.
|
1436 |
26188153
|
TLR2, TLR4, TLR7 and NLRP3-inflammasome signaling were not required for induction of this inflammatory response.
|
1437 |

Effector CD8 T cells in recipient mice were exposed to lipopolysaccharide (LPS), the Toll-like receptor 4 (TLR4) ligand, which significantly increased persistence.
|
1439 |

Flagellin-dependent TLR5/caveolin-1 as a promising immune activator in immunosenescence.
|
1457 |
26223660
|
The expression and activation of TLR5/MyD88, but not TLR4, were sensitively regulated by the upregulation of caveolin-1 in old macrophages through direct interaction.
|
1458 |
26223660
|
Because TLR5 and caveolin-1 were well expressed in major old tissues including lung, skin, intestine, and spleen, we analyzed in vivo immune responses via a vaccine platform with FlaB as a mucosal adjuvant for the pneumococcal surface protein A (PspA) against Streptococcus pneumoniae infection in young and aged mice.
|
1459 |
26223660
|
These results suggest that caveolin-1/TLR5 signaling plays a key role in age-associated innate immune responses and that FlaB-PspA stimulation of TLR5 may be a new strategy for a mucosal vaccine adjuvant against pneumococcal infection in the elderly.

We assayed the activation ex vivo and the responsiveness to TLR2 and TLR4 agonists in vitro in the three subsets and assessed the intracellular production of IL1-alpha (α), IL1-beta (β), IL-6, IL-8, TNF-α, and IL-10 of elderly adults (median 83 [67-90] years old;n= 20) compared with young controls (median 35 [27-40] years old;n= 20).
|
1461 |
26286603
|
Ex vivo, the elderly adults showed a higher percentage of classical monocytes that expressed intracellular IL1-α (p= .001), IL1-β (p= .001), IL-6 (p= .002), and IL-8 (p= .007).

One mechanism employed by monocytes for sensing foreign antigens is via toll-like receptors (TLRs)-transmembrane proteins that distinguish classes of foreign pathogens, for example, bacteria (TLR4, 5, and 9) vs. fungi (TLR2) vs. viruses (TLR3, 7, and 8).

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.

1466 |
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.

Prothymosin-alpha preconditioning inhibited the retinal ischemia-induced up-regulation of TLR4-related injury genes, and increased expression of TLR4-related protective genes.

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.
|
1469 |
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.

To investigate the molecular basis for these effects, we compared the reproductive pathologies and fertility rates in Chlamydia-infected wild-type (WT) and IL-10-knockout (IL-10(-/-)) mice; we also analyzed the expression of the Toll-like receptor (TLR)/interleukin-1 receptor (IL-1R) superfamily, IL-1β production, NLRP3 inflammasome assembly and activation, and the immunostimulatory capacity and apoptotic predilection of Chlamydia-exposed dendritic cells (DCs) from WT and IL-10(-/-) mice.
|
1486 |
26371131
|
Chlamydia-pulsed IL-10(-/-) DCs expressed larger numbers of TLR4/IL-1R molecules and had enhanced IL-1β production.
|
1487 |
26371131
|
In addition, NLRP3 inflammasome assembly was suppressed in IL-10(-/-) DCs through the inhibition of the P2X purinoceptor 7 (P2X7) receptor (P2X7R), an ATP-gated ion channel, and a decrease in intracellular Ca(2+) levels, which inhibited DC apoptosis.

Conversely, adsorption of monophosphoryl lipid A (MPLA) extracted from Salmonella minnesota, which is a TIR-domain-containing adapter-inducing interferon-β- (TRIF-) biased TLR4 agonist, was less effective in decreasing Th-2 responses.
