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.

|
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.

|
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.

|
Thus, distinct TLR agonists differentially modulate extracellular signal-regulated kinase signaling, c-Fos activity, and cytokine responses in DCs to stimulate different Th responses.

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).
|
111 |
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.
|
112 |
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.

Although TLR5 signaling was critical for mediating rapid macrophage-dependent clearance of flagellin-expressing tumor cells in vivo, TLR5 and NLRC4/NAIP5 were equally important for priming antitumor CD4(+) and CD8(+) T cells and suppressing tumor growth.
|
120 |
22323829
|
Vaccination with irradiated flagellin-expressing tumor cells prevented tumor development, and disrupting flagellin recognition by TLR5 or NLRC4/NAIP5 impaired protective immunization against an existing or subsequent tumor.
|
121 |
22323829
|
Here, we show that expression of the TLR ligand flagellin within tumor cells constitutes an effective antitumor vaccination strategy that relies on simultaneous engagement of TLR5 and the Nod-like receptors (NLRs) NLRC4/NAIP5 (neuronal apoptosis inhibitory protein 5) by flagellin along with associative recognition of tumor antigen for optimal antigen presentation to T cells.

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.
|
128 |
22497974

We explored the associations of different genotypes of SLA class II and of the genes TLR1, TLR4, TLR5, and TLR6 with antibody responses after vaccination against Erysipelothrix rhusiopathiae (ER) and Actinobacillus pleuropneumoniae (APP) serotypes 1, 2, and 5 in 191 Duroc pigs maintained under specific pathogen-free conditions.
|
130 |
22658914
|
We demonstrated close relationships between SLA class II and ER antibody response and between TLR genes other than TLR4 and APP antibody responses.

Moreover, we found toll-like receptor (TLR) agonists lipopolysaccharide (TLR4), fibroblast stimulating ligand-1 (TLR2/6), and ODN2006 (TLR7/9) induced reduced cytokine responses in aged mDC.
|
132 |
22953039
|
We also found that TLR4, TLR5, and innate negative regulator, sterile alpha and TIR motif containing protein (SARM), were all expressed at lower levels in young animals.
|
133 |
22953039
|
By contrast, absent in melanoma 2 and retinoic acid-inducible gene I expression was lowest in aged animals.

After 24 h of incubation, production of tumor necrosis factor alpha (TNF-α), interleukin-1 beta (IL-1β), IL-6, and IL-10 was measured in supernatants by enzyme-linked immunosorbent assay (ELISA).
|
135 |
23345580
|
The combinations of TLR2 and NOD2, TLR5 and NOD2, TLR5 and TLR3, and TLR5 and TLR9 acted as synergistic combinations.
|
136 |
23345580
|
Surprisingly, inhibitory interactions between TLR4 and TLR2, TLR4 and Dectin-1, and TLR2 and TLR9 as well as TLR3 and TLR2 were observed.
|
137 |
23831323
|
We noticed that TC-1 cells do not express Toll-like receptor 5 (TLR5) on their surface and the TLR5 signaling pathway in TC-1 cells was not responsible for the antitumor effect of FlaB.
|
138 |
23831323
|
In addition, this antitumor activity was abrogated following the in vivo depletion of CD8(+) T cells and in TLR5 knockout (KO) or MyD88 KO mice.
|
139 |
23831323
|
These results suggest that flagellin could enhance TA-specific CD8(+) CTL immune responses through TLR5 stimulation in cancer immunotherapy.

Toll-like receptor 3-mediated necrosis via TRIF, RIP3, and MLKL.
|
148 |
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.
|
149 |
24019532
|
In addition, TLR3 drives caspase 8-regulated programmed cell death pathways reminiscent of TNF family death receptor signaling.
|
150 |
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.
|
151 |
24019532
|
TLR3 or TLR4 directly activates programmed necrosis through a RIP homotypic interaction motif-dependent association of TRIF with RIP3 kinase (also called RIPK3).
|
152 |
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.
|
153 |
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.
|
154 |
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.

Prevention of intestinal allergy in mice by rflaA:Ova is associated with enforced antigen processing and TLR5-dependent IL-10 secretion by mDC.
|
157 |
24516564
|
Using TLR5(-/-) mDC the rflaA:Ova induced IL-10 secretion was shown to be TLR5 dependent.
|
158 |
24516564
|
In co-cultures of IL-10(-/-) mDC with DO11.10 T cells the lack of rflaA:Ova-mediated IL-10 secretion resulted in enhanced levels of both TH2 (IL-4, IL-5) and TH1 (IL-2 and IFN-y) cytokines.

Type 3 innate lymphoid cells (ILC3) are key players in antimicrobial defense in intestinal mucosa, through interleukin 17 and interleukin 22 (IL-22) production.
|
163 |
24577508
|
We first observed that lung mucosa harbors a discrete population of ILC3 expressing CD127, CD90, CCR6, and the transcriptional factor RORγt.
|
164 |
24577508
|
In addition, lung ILC3 were identified as a major source of IL-22 in response to interleukin 23 stimulation.
|
165 |
24577508
|
During Streptococcus pneumoniae infection, ILC3 rapidly accumulated in the lung tissue to produce IL-22.
|
166 |
24577508
|
In response to S. pneumoniae, dendritic cells and MyD88, an important adaptor of innate immunity, play critical functions in IL-22 production by ILC3.
|
167 |
24577508
|
Finally, administration of the Toll-like receptor 5 agonist flagellin during S. pneumoniae challenge exacerbated IL-22 production by ILC3, a process that protects against lethal infection.

24637756
|
Upon bacterial invasion into a host, flagellin functions as a pathogen-associated molecular pattern that is recognized by immune receptors, such as Toll-like receptor 5 (TLR5) and NAIP5/NLRC4, and activates host innate immunity against pathogens.
|
169 |
24637756
|
Future structure-based functional studies of paflagellin would extend the knowledge of the TLR5 or NAIP5/NLRC4 activation mechanisms of flagellin and would make a significant contribution to the design of flagellin vaccines and antiradiation therapeutics.

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.
|
175 |
25114104
|
Alongside increased parasite expulsion, MyD88-deficient mice showed heightened IL-4 and IL-17A production from mesenteric lymph node CD4(+) cells.
|
176 |
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.
|
177 |
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.
|
178 |
25114104
|
Like IL-1R1(-/-) and MyD88(-/-) mice, animals lacking signaling through the type 1 IFN receptor (i.e., IFNAR1(-/-)) also developed intestinal granulomas.
|
179 |
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.
|
180 |
25223833
|
The protective effect of the FliCi+P10 formulation required TLR-5, myeloid differentiation primary response gene 88 and IFN-γ expression, but caspase-1 knockout mice were only partially protected, suggesting that intracellular flagellin receptors are not involved with the anti-tumor effect.

Flagellin is a bacterial protein that stimulates the innate immune response via binding to extracellular Toll-like receptor 5 (TLR5) and also via interaction with intracellular NOD-like receptor C4 (NLRC4), leading to production of pro-inflammatory cytokines.

His-tagged GP5 was induced with IPTG, verified by SDS-PAGE and Western blotting, and purified to serve as an immunogen accompanied with the Salmonella typhimurium flagellin (FliC), a Toll-like receptor 5 (TLR5) agonist.

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.
|
185 |
26182986
|
Stimulation of the mononuclear cells with agonists to these TLRs increased the expression of downstream TLR signaling products (IL1α, IL6, IL12A and IFNβ).

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.
|
188 |
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.
|
189 |
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.
