114 17066089 Chronic lymphocytic leukemia (CLL) may be especially amenable to TLR agonists because it is an immunologically susceptible tumor with strong expression of several TLRs, particularly TLR-7 and TLR-9.

117 17073943 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).
118 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.
119 17073943 Mature DC pulsed with EXO(OVA), which were referred to as mDC(EXO), expressed a higher level of pMHC I, MHC II, and costimulatory CD40, CD54 and CD80 than DC(OVA).
120 17108047 While the majority of serotypes utilize coxsackievirus-adenovirus receptor (CAR) as their primary attachment receptor, subgroup B and subgroup D Ad37 serotypes use CD46.
121 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.
122 17108047 IFN-alpha induction correlated with the permissivity of pDCs to CD46- but not CAR-utilizing Ad serotypes.
123 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.
124 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.
125 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.

175 17651955 T. cruzi triggers both MyD88-dependent and TRIF-dependent innate activation pathways in macrophages and dendritic cells.
176 17651955 TLR-2 and TLR-9 recognize GPI anchors and parasite DNA, respectively; however other, as yet undefined receptors and ligands, also appear to be involved in innate recognition.
177 17713026 It has been shown that a single parenteral administration of vaccine containing bacterial ligands for TLRI, TLR2, TLR4, TLR6, and TLR9 in mice induced rapid (24 h after administration) and effective (100%), but short-term (96 h) protection against lethal challenge with Salmonella typhimurium.
178 17855554 MVA stimulation of bone marrow-derived dendritic cells (DC) showed that plasmacytoid DC were main alpha IFN (IFN-alpha) producers that were triggered independently of productive infection, viral replication, or intermediate and late viral gene expression.
179 17855554 Increased IFN-alpha levels were induced upon treatment with mildly UV-irradiated MVA, suggesting that a virus-encoded immune modulator(s) interfered with the host cytokine response.
180 17855554 Mice devoid of Toll-like receptor 9 (TLR9), the receptor for double-stranded DNA, mounted normal IFN-alpha responses upon MVA treatment.
181 17855554 Furthermore, mice devoid of the adaptors of TLR signaling MyD88 and TRIF and mice deficient in protein kinase R (PKR) showed IFN-alpha responses that were only slightly reduced compared to those of wild-type mice.
182 17855554 MVA-induced IFN-alpha responses were critically dependent on autocrine/paracrine triggering of the IFN-alpha/beta receptor and were independent of IFN-beta, thus involving "one-half" of a positive-feedback loop.

190 18071662 Because the immune system is naturally activated by foreign nucleic acids thanks to the presence of Toll-like Receptors (TLR) in endosomes (TLR3, 7, and 8 detect exogenous RNA, while TLR9 can detect exogenous DNA), the delivery of foreign nucleic acids usually induces an immune response directed against the encoded protein.
191 18077623 Following a demonstration that mouse-optimized cytosine-guanosine dinucleotide (CpG) oligodeoxynucleotides stimulated innate immune protection against intracellular pathogens, we tested the ability of CpG 7909, a primate-optimized Toll-like receptor 9 (TLR9) agonist, to stimulate rhesus macaques to produce interferon-inducible protein-10 (IP-10), a biomarker of immune activation.
192 18256672 Plasmid-DNA-activated, TBK1-dependent signalling and the resultant type-I interferon receptor-mediated signalling was required for induction of antigen-specific B and T cells, which occurred even in the absence of innate immune signalling through a well known CpG DNA sensor-Toll-like receptor 9 (TLR9) or Z-DNA binding protein 1 (ZBP1, also known as DAI, which was recently reported as a potential B-form DNA sensor).
193 18256672 Moreover, bone-marrow-transfer experiments revealed that TBK1-mediated signalling in haematopoietic cells was critical for the induction of antigen-specific B and CD4(+) T cells, whereas in non-haematopoietic cells TBK1 was required for CD8(+) T-cell induction.
194 18450485 However, readily dispersible adjuvants using TLR-9 and TLR-4 agonists skewed TCR repertoire usage by increasing TCR selection thresholds and enhancing antigen-specific clonal expansion.
195 18519662 Paired, but not solitary combinations of polyinosine:polycytadilic acid (P[I:C]; TLR3 agonist) and CpG DNA (ODN1826l; TLR9 agonist) stimulated IL-12 secretion from DCs in vitro and synergized with vaccination to achieve potent tumor rejection.
196 18641352 Adenovirus vector-induced innate inflammatory mediators, MAPK signaling, as well as adaptive immune responses are dependent upon both TLR2 and TLR9 in vivo.
197 18641352 The complexity of Ad-induced innate immune responses was confirmed when we also found that both TLR2 and MyD88 functions are required for the sustained activation of ERK1/2.

202 18758466 Inhibition of mTOR or its 'downstream' mediators, the p70 ribosomal S6 protein kinases p70S6K1 and p70S6K2, during pDC activation by Toll-like receptor 9 (TLR9) blocked the interaction of TLR9 with the adaptor MyD88 and subsequent activation of the interferon-regulatory factor IRF7, which resulted in impaired IFN-alpha/beta production.
203 19034349 TLR9 activation induces a Th1-like pattern of cytokine release which led to interest in the use of synthetic CpG oligodeoxynucleotides (CpG ODN) for the prevention and treatment of Th2-associated atopic disorders such as asthma.
204 19034349 Additional potential mechanisms of action include induction of regulatory-type responses (involving interleukin-10 release), and expression of indoleamine 2,3-dioxygenase.

230 19139565 By contrast, TLR9 was not highly expressed by naturally occurring CD4+CD25+ Treg or by Th1 and Th2 effector cells.
231 19139565 Furthermore, ingestion of calcitriol (1alpha25VitD3) by human volunteers led to an increase of both IL-10 and TLR9 expression by CD3+CD4+ T cells analyzed directly ex vivo.
232 19139565 Stimulation of 1alpha25VitD3-induced IL-10-secreting Treg with TLR9 agonists, CpG oligonucleotides, resulted in decreased IL-10 and IFN-gamma synthesis and a concurrent loss of regulatory function, but, unexpectedly, increased IL-4 synthesis.

238 19262501 Peripheral blood mononuclear cells and lymph node cells secreted significant amounts of interferon (IFN)-alpha, IFNgamma, and interleukin (IL)-12 following stimulation with CpG ODN.
239 19262501 PP cells spontaneously secreted high levels of IL-10, and the primary source of the IL-10 was resting CD5(-)CD11c(-)CD21(+) B cells.
240 19272649 Transcription of tumour necrosis factor-alpha (tnf alpha) and interleukin-6 (il6) genes, two cytokines directly related to TLR9 induction with unmethylated CpG oligodeoxynucleotides (CpG ODNs), was solely observed in head kidney and spleen of the fish immunised with pAE6-G.
241 19272649 Thus, the glycoprotein G of VHSV could be more implicated in triggering the pathways for TNF-alpha and IL6 production than the recognition of the unmethylated CpG motifs of the plasmid backbone by OmTLR9.
242 19273561 These two beta-glucans failed to stimulate TNF-alpha in Dectin-1 (beta-glucan receptor) knockout BMDCs.
243 19273561 The upregulation of TNF-alpha and downregulation of IL-12p70 required Dectin-1, but not IL-10.
244 19273561 Finally, costimulation of BMDCs with YGPs and either the TLR9 ligand, CpG, or the TLR2/1 ligand, Pam(3)CSK(4), resulted in upregulated secretion of IL-1alpha and IL-10 and downregulated secretion of IL-1beta, IL-6, and IFN-gamma-inducible protein 10 but had no significant effects on IL-12p40, keratinocyte-derived chemokine, monocyte chemotactic protein 1, or macrophage inflammatory protein alpha, compared with the TLR ligand alone.

248 19525489 Innate immune stimulants may have applications as vaccine adjuvants as well as in the treatment of cancer and some viral diseases, and clinical studies have been performed using agonists of Toll-like receptors (TLRs) 7, 8, and 9.
249 19578865 We investigated the effect of different toll like receptor (TLR) agonists including LPS (TLR4 agonist), polyinosinic acid-polycytidylic acid (PIC, TLR3 agonist), CpG oligonucleotide (TLR9 agonist), and imiquimod (TLR7 agonist) on human monocyte-derived dendritic cells (mdDCs) loading of human papillomavirus (HPV) type 11 E7 epitope.
250 19578865 This was characterized by an enhanced expression of CD40, CD80, CD86, CD83 and HLA-DR, and a high level of IL-12 production.
251 19641529 Here, we show that B-cells activated through the toll-like receptor-9 (TLR-9) and CD40 up-regulate surface expression of major histocompatibility complex and costimulatory molecules, produce IL-12, and exhibit potent antigen-presenting properties in vitro.
252 19786561 Our data demonstrate that combining ML0276 with either a Toll-like receptor 4 (TLR4) (EM005), TLR7 (imiquimod), or TLR9 (CpG DNA) agonist during immunization induces Th1 responses that limit local inflammation upon experimental M. leprae infection.
253 19822632 Toll-like receptor 2, TLR4, and TLR9 were each essential for generating robust cytokine and antibody responses.
254 19899953 For example, TLR4 is activated by lipopolysaccharide (LPS), whereas TLR9 responds to microbial DNA (CpGs).

256 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.
257 20051250 In contrast, poly(I:C) (TLR3 agonist) and LPS (TLR4 agonist) did not induce any of these responses.

267 20100933 We used multicolor flow cytometry and intracellular cytokine staining of myeloid DCs (mDCs) and plasmacytoid DCs (pDCs) and found substantial decreases in older compared with young individuals in TNF-alpha, IL-6, and/or IL-12 (p40) production in mDCs and in TNF-alpha and IFN-alpha production in pDCs in response to TLR1/2, TLR2/6, TLR3, TLR5, and TLR8 engagement in mDCs and TLR7 and TLR9 in pDCs.
268 20101095 Here, we have found that utilizing ligands for 3 TLRs (TLR2/6, TLR3, and TLR9) greatly increased the protective efficacy of vaccination with an HIV envelope peptide in mice when compared with using ligands for only any 2 of these TLRs; surprisingly, increased protection was induced without a marked increase in the number of peptide-specific T cells.
269 20101095 The triple combination increased production of DC IL-15 along with its receptor, IL-15Ralpha, which contributed to high avidity, and decreased expression of programmed death-ligand 1 and induction of Tregs.
270 20231693 In this study, we purified merozoites, food vacuoles, and parasite membrane fragments released during the Plasmodium falciparum schizont burst to homogeneity and tested for the activation of bone marrow-derived DCs from wild-type and TLR2(-/-), TLR4(-/-), TLR9(-/-), and MyD88(-/-) C57BL/6J mice.
271 20442853 Acquisition of adult-like TLR4 and TLR9 responses during the first year of life.
272 20451253 Production of monocyte chemoattractant protein-1 (MCP-1/CCL2), macrophage inflammatory protein-1 (MIP-1/CCL3) and regulated on activation, normal T cell expressed and secreted (RANTES/CCL5), were determined in cell culture supernatants by ELISA or cytokine cytometric bead array.
273 20451253 Pharmacological inhibitors of p38 mitogen-activated protein kinase (MAPK), extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK), nuclear factor-kappaB (NF-kB) and phosphatidylinositol 3-kinase (PI3K), were used to investigate the role of signaling pathways.
274 20451253 TLR agonists induced significantly elevated MCP-1, RANTES, and MIP-1.
275 20451253 Production of RANTES and MIP-1 was particularly prominent after stimulation of DCs with TLR3 (Poly(I:C)), and TLR7/8 (R848) or TLR9 (CpG ODN) agonists, respectively.
276 20451253 A positive role was identified for NF-kB, PI3K and ERK, whereas JNK had a negative regulatory effect on chemokine production in DCs.
277 20451253 Positive and negative regulatory roles for the p38 MAPK pathway were observed.
278 20466823 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.
279 20466823 We have demonstrated previously that CD4-8- DCs secreting TGF-beta stimulate CD4+ Tr1 cell responses.
280 20466823 Here, we have assessed whether TLR4 and TLR9 signaling through LPS and CpG stimulation can convert CD4-8- DC-induced tolerance.
281 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.
282 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.
283 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.
284 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.
285 20551621 This was confirmed by kinome analysis which demonstrated dynamic patterns of phosphorylation of key TLR adaptor proteins such as IRAK1, TAK1, IKK and NF-kappaB-p65 in CpG-stimulated blood CD21+ B cells, consistent with activation of the TLR9 pathway.
286 20610663 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.
287 20610663 We demonstrated that TLR9 activation by F. nucleatum and TLR2 activation by both bacteria appear to be involved in HIV-1 reactivation; however, TLR4 activation had no effect.

310 20875795 These responses were almost comparable, but slightly weaker, in TLR2-, TLR4- and TLR7-deficient mice relative to wild-type mice, suggesting that this enhancing effect is not due to plausible LPS contamination.
311 20877154 Transcription of TLR2, TLR4, and TLR9 mRNA on canine CD21(+) cells was confirmed by reverse-transcript polymerase chain reaction (RT-PCR).
312 20877154 Quantification of IL-6, IL-10, and IL-12p40 mRNA transcription on canine CD21(+) cells revealed that CpG-ODNs enhanced IL-6 mRNA transcription but not IL-10 and IL-12p40 mRNA transcription (P<0.05 compared with control-ODNs).
313 20937315 The adjuvant effects of the TLR7 agonist, imiquimod, and the TLR9 agonist, ODN1826, were tested with rAAV expressing the melanoma antigen, Trp2.

318 21173782 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.
319 21173782 Results showed that TLR2(-/-), TLR4(-/-)and TLR7(-/-) mice survived ECTV infection whereas MyD88(-/-) and TLR9(-/-)mice, in contrast, were highly susceptible.
320 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.
321 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.
322 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.

329 21248035 Antigen-specific T-cell responses to a recombinant fowlpox virus are dependent on MyD88 and interleukin-18 and independent of Toll-like receptor 7 (TLR7)- and TLR9-mediated innate immune recognition.
330 21248035 We show that Toll-like receptor 7 (TLR7) and TLR9 are important for type I interferon secretion by dendritic cells, while TLR9 is solely required for proinflammatory cytokine secretion.
331 21248035 Despite this functional role for TLR7 and TLR9 in vitro, only the adapter protein myeloid differentiation primary response gene 88 (MyD88) was shown to be essential for the formation of adaptive immunity to FWPV(OVA) in vivo.
332 21248035 We demonstrate that this is not by means of mediating T-cell-dependent interleukin-1 (IL-1) signaling, but rather, we suggest that MyD88 functions to support T-cell-specific IL-18 receptor signaling, which in turn is essential for the formation of adaptive immunity to FWPV-encoded OVA.

341 21288993 Both B. breve and lactobacilli induced cytokines in a Toll-like receptor 9 (TLR9)-dependent manner, while the lower inflammatory profile of B. breve was due to inhibitory effects of TLR2.
342 21288993 No role for TLR4, NOD2, and C-type lectin receptors was apparent.
343 21325490 A somewhat increased NK cell response, increased dendritic cell expression of TLR3 and -9, and increased TLR-induced alpha interferon responses were also noted.
344 21403403 This endogenous immunostimulatory activity required nucleic acid and protein for its adjuvant effect and activated antigen-presenting cells through the RNA and DNA sensors TLR8 and TLR9.
345 21515797 SIV infections of SMs are characterized by an absence of chronic immune activation, in association with significantly reduced IFN-α production by plasmacytoid dendritic cells (pDCs) following exposure to SIV or other defined TLR7 or TLR9 ligands.
346 21687712 These were tested for their ability to activate DCs obtained by the FLT3 ligand differentiation of bone marrow cells from the wild type, and TLR2(-/-), TLR9(-/-) and MyD88(-/-) mice.
347 21742006 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).
348 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.
349 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.
350 21742006 In conclusion, Pam(2)CSK(4) should be evaluated as a candidate adjuvant for a C. trachomatis vaccine.
351 21835795 Myxoma virus induces type I interferon production in murine plasmacytoid dendritic cells via a TLR9/MyD88-, IRF5/IRF7-, and IFNAR-dependent pathway.
352 21835795 Using pDCs derived from genetic knockout mice, we show that the myxoma virus-induced innate immune response requires the endosomal DNA sensor TLR9 and its adaptor MyD88, transcription factors IRF5 and IRF7, and the type I IFN positive-feedback loop mediated by IFNAR1.
353 21835795 It is independent of the cytoplasmic RNA sensing pathway mediated by the mitochondrial adaptor molecule MAVS, the TLR3 adaptor TRIF, or the transcription factor IRF3.
354 21835795 Using pharmacological inhibitors, we demonstrate that myxoma virus-induced type I IFN and IL-12p70 production in murine pDCs is also dependent on phosphatidylinositol 3-kinase (PI3K) and Akt.

356 21921206 Using a total of 28 baboons, different vaccination strategies were used including recombinant Sm-p80 protein formulated in Toll-like receptor 7 and Toll-like receptor 9 agonists, and DNA priming followed by boosting with protein plus adjuvants.
357 21921206 Production and expression of several cytokines (interleukin 2 [IL-2], interferon γ, IL-12α, IL-1β, IL-6, and IL-22) were up-regulated in vaccinated animals.
358 22120194 We reason that a strategy capable of improving CD8+ T cell activation would improve the efficacy of protein-based vaccines, which predominantly generate CD4+ T cell-mediated responses.
359 22120194 Herein, we explore the ability of a novel cell-penetrating peptide (CPP), LAH4, to facilitate intracellular delivery of protein-based vaccines adjuvanted with Toll-like receptor 9 agonist CpG oligonucleotide (CpG) to generate enhanced CD8+ T cell immune responses and antitumor effects.
360 22120194 Furthermore, we found that LAH4 was able to enhance the ability of a tyrosinase-related protein 2 (TRP-2) peptide-based vaccine to generate TRP2-specific CD8+ T cells and antitumor effects against TRP2-expressing tumors.
361 22120195 Induction of mucosal and systemic immunity against respiratory syncytial virus by inactivated virus supplemented with TLR9 and NOD2 ligands.
362 22120195 Addition of TLR9/NOD2 ligands to the inactivated RSV also promoted affinity maturation of RSV-specific IgG antibodies and shifted T cell responses from mainly IL-5-secreting cells to predominantly IFN-γ-producing cells, indicating a Th1-skewed response.
363 22120195 Finally, BPL-RSV supplemented with TLR9/NOD2 ligands significantly improved the protection efficacy against a challenge with infectious virus, without stimulating enhanced disease as evidenced by lack of eotaxin mRNA expression and eosinophil infiltration in the lung.
364 22120195 We conclude that mucosal immunization with inactivated RSV antigen supplemented with TLR9/NOD2 ligands is a promising approach to induce effective RSV-specific immunity without priming for enhanced disease.

378 22120532 Chicken TLR3 and TLR21 (avian equivalent to mammalian TLR9) recognize poly I:C (double-stranded RNA) and CpG-ODN (a CpG-motif containing oligodeoxydinucleotide), respectively.
379 22120532 The objective of the present study was to investigate the effect of the interaction between poly I:C and CpG-ODN on the mRNA expression levels of IFN-α and IFN-β, Th1 cytokines IFN-γ and IL-12, Th2 cytokine IL-4, and regulatory IL-10 in chicken monocytes.
380 22169598 In in vitro glioma cells, there was a positive correlation between the protein levels of TLR9 and both matrix metalloproteinase (MMP)-2 and MMP-9 (p<0.05), but no relationship between TLR9 levels and levels of interleukin-6, transforming growth factor-β2 or signal transducer and activator of transcription (STAT)-3 (p>0.05).
381 22470545 Addition of the TLR3 and TLR9 agonists significantly increased the adjuvanting capacity of MLVs and OVA-encapsulating dehydration-rehydration vesicles (DRVs), but not of SUVs.
382 22497974 We then examined cells with single or multiple virus infections for the expression of 10 cytokine genes and demonstrated elevated expressions for 7 (IFN-α, IFN-β, IFN-γ, TNF-α, IL-6, IL-8, and IL-17) in dual rotavirus and enterovirus or triple rotavirus, enterovirus and astrovirus-infected cells but only 3 (IFN-β, TNF-α, and IL-8) in dual rotavirus and astrovirus-infected cells.
383 22497974 We further observed elevated levels of TLR4, TLR5, TLR7 and TLR9 mRNAs in cells with rotavirus and enterovirus or rotavirus, enterovirus and astrovirus infections when compared to single rotavirus infections.
384 22662179 LOS activates the host immune response through a membrane bound CD14-TLR4 complex, while both heat killed and live M.cat require recognition by multiple toll like receptors such as TLR2, TLR4 and TLR9 without the requirement of CD14.
385 22662179 We finally showed that TLR4 mutant C3H/HeJ mice produce significantly lower levels of pro-inflammatory cytokines TNF-α and IL-6 in vivo, An increased bacterial loads at 12 and 24 hours (P<0.001) in their lungs upon challenge with live M.cat in an aerosol chamber compared to wild-type (WT) control mice.
386 22875539 However, analyses of (1) IL-10 production following in vitro stimulation of immunized Balb/c mice splenocytes by TTd, β2GPI or glutaraldehyde-treated β2GPI and (2) specific impact of ConA and agonists of TLR2, TLR4, and TLR9 on anti-TTd and autoreactive Abs secretion strongly imply that these two branches of the TTd-induced immune response do not use identical cell populations and are regulated in a different way.

425 23521528 We have engineered a nononcogenic mutated E7-specific plasmo-retroVLP vaccine (pVLP-E7), consisting of plasmid DNA, that is able to form recombinant retrovirus-based virus-like particles (VLPs) that display E7 antigen into murine leukemia virus Gag proteins pseudotyped with vesicular stomatitis virus envelope glycoprotein (VSV-G). pVLP-E7 vaccinations were studied for their ability to generate specific immune responses and for induction of protective immunity against tumor cell challenge in preventive and therapeutic models.
426 23521528 Intradermic vaccinations of mice with pVLP-E7 show their efficacy to generate antigen-specific T cell responses, to prevent and protect animals from early TC-1 tumor development compared with standard DNA or VLP immunizations.
427 23521528 Data show that pVLP-E7 vaccination can cure mice with already established tumors only when combined with Toll-like receptor-7 (TLR7) and TLR9 agonists.
428 23533581 Involvement of DNA-PKcs in the IL-6 and IL-12 response to CpG-ODN is mediated by its interaction with TRAF6 in dendritic cells.

443 23750720 In contrast to humans, pDC in rhesus macaques expressed the interleukin (IL)-12p40 subunit in response to TLR-7/8 as well as TLR-9 stimulation.
444 23781340 In this study, IFN-gamma treatment of bone marrow-derived DC, followed by incubation with the TLR2, TLR4, or TLR9 agonists, enhanced DC activation compared to TLR ligation alone.
445 23781340 Most notably, the upregulation of CD40 with LPS stimulation and CD86 with CpG stimulation was observed in in vitro cultures.
446 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.
447 23850441 Activations of endosomal TLRs include TLR3, TLR7/8, and TLR9 stimulates the production of cytokines, such as type I interferons (IFNs), and therefore involves in virus-host interactions.
448 23850441 Our results showed that EIAVFDDV13 dramatically up-regulated the expression of TLR3 and IFNβ and less robustly up-regulated the expression of TRL9 and IFNα1, whereas EIAVFDDV3-8 induced significantly lower expression of type I IFN mRNA and protein and more strongly down-regulated the expression of TLR7 and TLR8.
449 23884215 Mice lacking IRF3, IFN-α receptor, IL-1β/IL-18, TLR9 or MyD88 showed similar CTL responses to wild-type mice, arguing that none of these molecules were required for the immunogenicity of DNA vaccines.
450 23912942 TLR7/8-triggered secretion of IL-12 and IFN-α, as well as TLR9-triggered secretion of IL-12, was hyperactivated.
451 23935491 Blocking TLR7- and TLR9-mediated IFN-α production by plasmacytoid dendritic cells does not diminish immune activation in early SIV infection.
452 23935491 We show that pDC are major but not exclusive producers of IFN-α that rapidly become unresponsive to virus stimulation following SIV infection, whereas myeloid DC gain the capacity to produce IFN-α, albeit at low levels. pDC mediate a marked but transient IFN-α response in lymph nodes during the acute phase that is blocked by administration of TLR7 and TLR9 antagonist without impacting pDC recruitment.

477 24019532 Toll-like receptor 3-mediated necrosis via TRIF, RIP3, and MLKL.
478 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.
479 24019532 In addition, TLR3 drives caspase 8-regulated programmed cell death pathways reminiscent of TNF family death receptor signaling.
480 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.
481 24019532 TLR3 or TLR4 directly activates programmed necrosis through a RIP homotypic interaction motif-dependent association of TRIF with RIP3 kinase (also called RIPK3).
482 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.
483 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.
484 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.

556 24463331 The polyepitope protein includes contiguous multiple MHC class I-restricted epitopes with an aim to induce CD8(+) T cell immunity, while gB is an important target for CD4(+) T cell immunity and neutralizing antibodies.
557 24463331 Optimal immunogenicity of this bivalent non-live protein vaccine formulation was dependent upon the co-administration of both the TLR4 and TLR9 agonist, which was associated with the activation of innate immune signatures and the influx of different DC subsets including plasmacytoid DCs and migratory CD8-DEC205+CD103-CD326- langerin-negative dermal DCs into the draining lymph nodes.

561 24534144 The aim of the present study was to evaluate the expression of TLR3, TLR7 and TLR9 in porcine alveolar macrophages (PAM) infected with different genotype 1 PRRSV strains previously sequenced and characterized by their ability to induce TNF-α: 3262 (TNF-α inducer), 3267 (TNF-α not inducer) and an attenuated vaccine strain (strain Deventer, PorcilisPRRS, Merck) that replicates scarcely in PAM.
562 24534144 Thus, in PAM infected with PRRSV strain 3262 the proportion of TLR3+ cells significantly increased from 24h compared with the controls; in contrast strain 3267 resulted in a lower proportion of TLR3+ PAM.

566 24632732 In a PP cell culture system, b240 promoted the production of immunoglobulin A (IgA), interleukin (IL)-6, IL-10, interferon (IFN)-γ, and tumor necrosis factor, but not IL-4, IL-5, B-cell activating factors, IFN-α, IFN-β, and transforming growth factor-β1.
567 24632732 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.
568 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.

570 24648995 Vaccination with pVAX1-Sj26GST in combination with CpG inhibited Treg immunosuppressive function, upregulated the production of interferon (IFN)-γ, tumor necrosis factor (TNF)-α, interleukin (IL)-4, IL-10, IL-2 and IL-6, and decreased CD4+CD8+Foxp3+ expression in vitro, which may contribute to the escape from Treg-mediated suppression during vaccination, allowing expansion of antigen-specific T cells against pathogens.
571 24720881 It is well established that CpG oligonucleotides (ODN), a widely studied Toll-like receptor 9 (TLR9) agonist, used to enhance Th1 response, also induces high levels of the anti-inflammatory, Th2-promoting cytokine IL10, which could dampen the resulting Th1 response.
572 24720881 Co-delivery of poly(I:C), a TLR3 agonist had only minor effects on IL10 levels.

582 25114104 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.
583 25114104 Alongside increased parasite expulsion, MyD88-deficient mice showed heightened IL-4 and IL-17A production from mesenteric lymph node CD4(+) cells.
584 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.
585 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.
586 25114104 Like IL-1R1(-/-) and MyD88(-/-) mice, animals lacking signaling through the type 1 IFN receptor (i.e., IFNAR1(-/-)) also developed intestinal granulomas.
587 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.
588 25224571 Recently, it has been noted that TLRs on tumor cells are involved in tumor development, and several TLR agonists, such as the TLR3 agonist poly(I:C) and the TLR9 agonist CpG ODN, are being developed as vaccine adjuvants and cancer immunotherapeutics.

607 25536171 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.
608 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).
609 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.
610 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.
611 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.
612 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.
613 25536171 Unexpectedly, B cells also failed to undergo CSR or plasma cell differentiation when co-stimulated by LPS and CD154.
614 25536171 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.

627 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.
628 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.
629 25536171 Unexpectedly, B cells also failed to undergo CSR or plasma cell differentiation when co-stimulated by LPS and CD154.
630 25536171 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.
631 25536171 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.
632 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).
633 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.

639 25548274 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.
640 25646304 Therapeutic protection required IFN-γ and CD8(+) T cells, whereas NK and CD4(+) T cells were found to be redundant.
641 25646304 ISCOMATRIX vaccines combined with TLR3 and TLR9 agonists represent a promising cancer immunotherapy strategy.
642 25762407 Here, we used CpG-C together with the clinically relevant saponin-based adjuvant AbISCO-100/Matrix-M (AbISCO), to assess if TLR9 co-stimulation would quantitatively or qualitatively modulate HIV-1 envelope glycoprotein (Env)-specific B and T cell responses in rhesus macaques.
643 25775582 Immunomodulatory nucleic acids act by agonizing or antagonizing endosomal toll-like receptors (TLR3, TLR7/8, and TLR9), proteins involved in innate immune signaling.
644 25888637 Immunization with microparticles containing TLR9 and NOD-2 ligands (MIS416) significantly prolonged survival in tumor-bearing mice.
645 26022572 A TLR4 agonist is part of a licensed vaccine and TLR9 ligands are in late stage clinical testing.
646 26093207 Furthermore, significant induction of TLR9, Mx and IL-1β was observed in the spleen on day 7 post-vaccination, supporting that the vaccine could trigger TLR9 signaling.
647 26093207 Interestingly, at week 2 the ODN appeared to induce a Th1-like response, as indicated by upregulation of T-bet (a Th1 marker) and downregulation of GATA-3 (a Th2 marker).
648 26140240 Comparison of chemokines induced in the bladder by either CpG (a TLR-9 agonist) or Ty21a highlighted the preferential increase in complement component 5a, CXCL5, CXCL2, CCL8, and CCL5 by Ty21a, suggesting their involvement in the attraction of T cells to the bladder.
649 26182986 We isolated RNA from peripheral blood mononuclear cells and, with PCR, detected transcripts for TLRs 2, 3, 4, 5, 6, 7, 8, 9, 10 and 13.
650 26182986 Stimulation of the mononuclear cells with agonists to these TLRs increased the expression of downstream TLR signaling products (IL1α, IL6, IL12A and IFNβ).
651 26395101 In response to microbial pattern molecules, these DCs upgrade the maturation stage sufficient to improve cross-presentation of exogenous Ag, and upregulation of MHC and costimulators, allowing CD4/CD8 T cells to proliferate and liberating cytokines/chemokines that support lymphocyte attraction and survival.
652 26395101 Mouse CD8α(+) DCs express TLR7 and TLR9 in addition to the TLR2 family (TLR1, 2, and 6) and TLR3, whereas human CD141(+) DCs exclusively express the TLR2 family and TLR3.
653 26395101 In contrast, TLR2 and TLR3 are similarly expressed in both human and mouse Ag-presenting DCs.
654 26395101 Bacillus Calmette-Guerin peptidoglycan and polyinosinic-polycytidylic acid are representative agonists for TLR2 and TLR3, respectively, although they additionally stimulate cytoplasmic sensors: their functional specificities may not be limited to the relevant TLRs.
