3 10525448 Interleukin (IL)-18 is a newly discovered cytokine, structurally similar to IL-1, with profound effects on T-cell activation.
4 10525448 Formerly called interferon (IFN) gamma inducing factor (IGIF), IL-18 is the new name of a novel cytokine that plays an important role in the T-cell-helper type 1 (Th1) response, primarily by its ability to induce IFNgamma production in T cells and natural killer (NK) cells.
5 10525448 Mice deficient in IL-18 have suppressed IFNgamma production despite the presence of IL-12 IL-18 is related to the IL-1 family in terms of structure, receptor family, and function.
6 10525448 In terms of structure, IL-18 and IL-1beta share primary amino acid sequences of the so-called "signature sequence" motif and are similarly folded as all-beta pleated sheet molecules.
7 10525448 Also similar to IL-1beta, IL-18 is synthesized as a biologically inactive precursor molecule lacking a signal peptide which requires cleavage into an active, mature molecule by the intracellular cysteine protease called IL-1beta-converting enzyme (ICE, also called caspase-1).
8 10525448 The activity of mature IL-18 is closely related to that of IL-1.
9 10525448 IL-18 induces gene expression and synthesis of tumor necrosis factor (TNF), IL-1, Fas ligand, and several chemokines.
10 10525448 This IL-18R complex is made up of a binding chain termed IL-18Ralpha, a member of the IL-1 receptor family previously identified as the IL-1 receptor-related protein (IL-1Rrp), and a signaling chain, also a member of the IL-1R family.
11 10525448 The IL-18R complex recruits the IL-1R-activating kinase (IRAK) and TNFR-associated factor-6 (TRAF-6) which phosphorylates nuclear factor kappaB (NFkappaB)-inducing kinase (NIK) with subsequent activation of NFkappaB.
12 10525448 Thus on the basis of primary structure, three-dimensional structure, receptor family, signal transduction pathways and biological effects, IL-18 appears to be a new member of the IL-1 family.
13 10525448 Similar to IL-1, IL-18 participates in both innate and acquired immunity.
14 10607486 After a 6-h incubation, phenotypic analysis of control-, imiquimod-, or R-848-treated LC indicated that such antigen-presenting cells were in an "intermediate" state of maturation (CD1a(+), HLA-DR, DP, DQ(bright+), CD40(low+), CD86(high+), and CD80(low+)).
15 10607486 RNase protection assays demonstrated that either imiquimod or R-848 treatments increased steady-state transcripts encoding for IL-12 p40, IL-1beta, TNF-alpha, and IL-1 receptor antagonist by LC.
16 11063823 In this study we report that IL-1beta concentrations were significantly increased in the hippocampus following subcutaneous (s.c.) injection of Pw, and that this was accompanied by increased activity of the stress-activated kinase, c-Jun-N-terminal kinase (JNK) and a decrease in glutamate release.
17 11063823 Incubation of hippocampal synaptosomes in the presence of Pw, PT or LPS also resulted in increased JNK activation and decreased glutamate release, effects which were mimicked by IL-1beta and blocked by the IL-1 receptor antagonist (IL-ra).
18 11401957 Seizure-like behavioral changes were significantly reduced following inhibition of IL-1beta production by the administration of an inhibitor of IL-1beta-converting enzyme and were almost completely abrogated in IL-1 receptor type I knockout mice.
19 11401957 Significantly, Pa neither increased IL-1beta nor induced behavioral changes in mice, but did induce the anti-inflammatory cytokine IL-10.
20 11441107 Cooperation of Toll-like receptor 2 and 6 for cellular activation by soluble tuberculosis factor and Borrelia burgdorferi outer surface protein A lipoprotein: role of Toll-interacting protein and IL-1 receptor signaling molecules in Toll-like receptor 2 signaling.
21 11441107 Toll-like receptor 2 (TLR2) and TLR4 play important roles in innate immune responses to various microbial agents.
22 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.
23 11441107 We further characterized the signaling pathway in response to STF, OspA-L, and PSM in TLR2-transfected HMEC.
24 11441107 The TLR2 signaling pathway for NF-kappaB trans-activation shares the IL-1R signaling molecules.
25 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.
26 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.
27 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.
28 11441107 Our data also suggest that Tollip may be an important constituent of both the TLR2 and TLR4 signaling pathways.
29 12230303 Some cases of AD are caused by mutations in presenilin-1 (PS1), and it has been shown that PS1 mutations perturb neuronal calcium homeostasis, promote increased production of amyloid beta-peptide (Abeta), and render neurons vulnerable to synaptic dysfunction, excitotoxicity, and apoptosis.
30 12230303 LPS-induced levels of mRNAs encoding tumor necrosis fctor-alpha (TNFalpha), interleukin (IL)-1alpha, IL-1beta, IL-1 receptor antagonist, and IL-6 are significantly greater in the hippocampus and cerebral cortex of PS1 mutant mice as compared to wild-type mice.
31 12230303 Studies of cultured microglia from PS1 mutant and wild-type mice reveal that PS1 is expressed in microglia and that the PS1 mutation confers a heightened sensitivity to LPS, as indicated by superinduction of inducible nitric oxide synthase (NOS) and activation of mitogen-activated protein kinase (MAPK).
32 12620640 These Pw-induced changes were accompanied by an increase in caspase-1 and interleukin-1beta (IL-1beta), and were associated with increased activity of the stress-activated kinase, p38.
33 12620640 In contrast, immunization with Pa failed to activate pro-inflammatory IL-1 responses but resulted in increased IL-1 receptor antagonist (IL-1ra) production.
34 12626603 For all volunteers, single nucleotide polymorphisms were determined for the following UV response-related cytokines: IL-1 receptor antagonist (+2018), IL-1 alpha (+4845), IL-1 beta (+3953), TNF-alpha (-308), and TNF-alpha (-238).
35 12738360 We first demonstrated that this method is adequate to measure the induction of interleukin (IL)-1beta and IL-1 receptor antagonist (IL-1 RA) mRNA upon the addition of bacterial lipopolysaccharide (LPS) to whole blood.
36 12738360 Finally, we demonstrated that this methodology can be used successfully to assess inflammatory as well as T cell responses in vivo, as it allowed to detect the induction of IL-1beta and IL-1 RA after injection of LPS in healthy volunteers, and also the induction of IL-2 upon recall immunisation with tetanus vaccine.
37 12763679 There are over 300,000 patients worldwide being treated with agents that specifically block the biological activities of interleukin-1 (IL-1) or tumor necrosis factor (TNF) for reducing the severity of autoimmune diseases such as rheumatoid arthritis, Crohn's disease or psoriasis.

39 12763679 Blockade of IL-1 activity with the IL-1 receptor antagonist (IL-1Ra) appears, at present, to be relatively safe.
40 12763679 From a wealth of rodent studies using live infection models, the following conclusions can be drawn: (1) neutralization or gene deletion for TNF-alpha is frequently associated with reduction of host defense in models of live Gram-positive or Gram-negative infections as well as infection by intracellular microbes such as Salmonella and Listeria; (2) absence of the IL-1 receptor can also result in decreased resistance to Listeria or Gram-positive bacteria and (3) TNF-alpha and IFN-gamma are required for defense against infection caused by Mycobacterium tuberculosis.
41 12763679 There are over 300,000 patients worldwide being treated with agents that specifically block the biological activities of interleukin-1 (IL-1) or tumor necrosis factor (TNF) for reducing the severity of autoimmune diseases such as rheumatoid arthritis, Crohn's disease or psoriasis.

44 12763679 From a wealth of rodent studies using live infection models, the following conclusions can be drawn: (1) neutralization or gene deletion for TNF-alpha is frequently associated with reduction of host defense in models of live Gram-positive or Gram-negative infections as well as infection by intracellular microbes such as Salmonella and Listeria; (2) absence of the IL-1 receptor can also result in decreased resistance to Listeria or Gram-positive bacteria and (3) TNF-alpha and IFN-gamma are required for defense against infection caused by Mycobacterium tuberculosis.
45 15068376 As interleukin 1 (IL-1) plays an essential role in augmenting both cellular and humoral immune responses to foreign antigens, it may represent a good candidate for an adjuvant to DNA vaccines.
46 15068376 Since the inflammatory activity of IL-1 may have a restricted application to DNA vaccines, we explored the possibility of augmenting immune response without unwanted inflammatory effect using IL-1beta 163-171 peptide, which is essential for IL-1 receptor 1 binding.
47 15356430 Urinary tract diseases revealed after DTP vaccination in infants and young children: cytokine irregularities and down-regulation of cytochrome P-450 enzymes induced by the vaccine may uncover latent diseases in genetically predisposed subjects.
48 15356430 It is suggested that the whole-cell pertussis present in DTP vaccine, acting as an excessive stimulus in these patients, produced symptoms reminiscent of biologic responses to circulating proinflammatory monokines such as IL-1beta, TNF-alpha, and IL-6 because earlier it was reported that in vitro the whole-cell vaccine induced significantly more such cytokine production than did the acellular pertussis or diphtheria-tetanus-only vaccine.
49 15356430 Analysis of the cellular immune disturbances previously reported in urinary tract infection/inflammation (increased serum and/or urinary IL-1alpha, IL-1 receptor antagonist, IL-6 and IL-8), steroid-sensitive nephrotic syndrome (increased IL-2, IFN-gamma, TNF-alpha, and decreased or increased IL-4, depending on the cells studied), and atopic dermatitis (decreased IFN-gamma and increased IL-4 production), may suggest that similar subclinical chronic cytokine-mediated abnormalities produced in the course of latent diseases revealed in our patients, combined with those caused by DTP vaccination stimulus, were responsible for the pathomechanism of these clinical entities.
50 15356430 This speculation is in agreement with the reports on the long-lasting induction of cytokine release and down-regulation of hepatic cytochrome P-450 isoenzyme activities after administration of DTP vaccine to mice and may be supported by the fact that TH1 phenotype is associated with the up-regulation of intercellular adhesion molecule-1 and RANTES, whereas TH2 phenotype is associated with the up-regulation of the vascular cell adhesion molecule and P-selectin, which are key players in the migration into inflamed tissues and localization of lymphocytes and other allergic effector and inflammatory cells.
51 15356430 Because several inflammatory cytokines down-regulate gene expression of major cytochrome P-450 and/or other enzymes with the specific effects on mRNA levels, protein expression, and enzyme activity, thus affecting the metabolism of several endogenous lipophilic substances such as steroids, lipid-soluble vitamins, prostaglandins, leukotrienes, thromboxanes, and exogenous substances, their irregularities in the body may eventually lead to the flare of latent diseases in some predisposed subjects.
52 15356430 Also, interleukin genetic polymorphisms, especially the constellation of TNF-alpha and IL-6 genetic variants, might predispose some infants with infection to a more than usually intense inflammatory response in the kidneys after vaccination.
53 15727290 Since the inflammatory activity of IL-I may restrict its application in DNA vaccine treatment, we explored the possibilities of augmenting immune responses without unwanted inflammatory effects using the IL-1beta fragment (amino acids (aa) 163-171), which is essential for IL-1 receptor-1 binding.
54 16005738 Improvement of collagen-induced arthritis by active immunization against murine IL-1beta peptides designed by molecular modelling.
55 16005738 Strategies designed to blocking IL-1beta by passive administration of inhibitors (mAbs, IL-1 receptor antagonist) have previously demonstrated efficacy in rheumatoid arthritis (RA).

57 16245793 MyD88/TRIF double defi-indicating that innate immunity is involved in anti-mycobacterial infection. (1) SNP (single nucleotide polymorphism) analysis in association with Mycobacterium tuberculosis: Taro SHIRAKAWA (Department of Health Promotion & Human Behavior, Kyoto University Medical School, and RIKEN SRC Center) Candidate gene approach was made on 18 SNPs in 11 genes in association with M. tuberculosis.
58 16245793 In TLR signaling pathways, Toll/IL-1 receptor (TIR) domain-containing adaptors, such as MyD88, TIRAP, TRIF, and TRAM, have been shown to play pivotal roles.
59 16245793 MyD88/TRIF double deficient mice, in which TLR-dependent activation of innate immunity is abolished, showed high sensitivity to mycobacterial infection, indicating that innate immunity is critically involved in anti-mycobacterial responses.
60 18253928 Therapeutic administration of recombinant IL-1 receptor antagonist (IL-1Ra) is efficacious in reducing clinical symptoms of disease, but suffers from several drawbacks, including the need for frequent administrations of large amounts.
61 18253928 In the T and B cell-independent collagen Ab transfer model, immunization with the IL-1beta vaccine strongly protected from arthritis, whereas immunization with the IL-1alpha vaccine had no effect.
62 19489682 The association of interleukin-1beta (IL-1B) -511C > T and IL-1 receptor antagonist (IL-1RN) VNTR, transforming growth factor-beta (TGF-B1) +28C > T and interferon-gamma (IFN-G) + 874T>A polymorphisms with bladder cancer (CaB) susceptibility and risk of recurrence in Bacillus Calmette-Guérin (BCG)-treated patients was analyzed in 287 controls and 213 CaB patients (73 BCG treated).
63 19489682 TGF-B TT and IFN-G +874 A carriers were associated with reduced (hazard ratio (HR) 0.37) and enhanced (HR 2.24) risk of recurrence after BCG immunotherapy, respectively.
64 20083674 Upon BCG phagocytosis, CD11b(+)Ly-6C(int)Ly-6G(-) cells produced NO, which required the IL-1 receptor.
65 20445007 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.
66 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.
67 20445007 PAM stimulation also induced IL-1beta, IL-6, and IL-8.
68 20445007 Delaying the addition of DEX until 6 h after LPS stimulation failed to decrease TNF or IL-6.
69 20445007 In contrast, delayed DEX addition significantly suppressed PAM-induced IL-1beta, IL-6, or IL-8 and also suppressed LPS-induced IL-1beta and IL-8.
70 21036709 IL-1 receptor antagonist anakinra enhances tumour growth inhibition in mice receiving peptide vaccination and beta-(1-3),(1-6)-D-glucan.
71 21540455 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.
72 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.
73 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.
74 21540455 We show that the TRIF-biased signaling that is characteristic of low-toxicity MLA explains its failure to activate caspase-1.
75 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.
76 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.
77 21652516 Priming of naive CD8 T cells by dendritic cells (DCs) entails both effective antigen presentation on MHC class I products and co-stimulatory signaling.
78 21652516 To test whether it is possible to equip the resulting MHC-I complexes with an inherent ability to activate antigen-presenting cells, we engrafted the intracellular Toll/IL-1 receptor domain of mouse Toll-like receptor (TLR) 4 or TLR2 onto the peptide-β(2)m scaffold.
79 23056330 Several recent studies have linked vaccine-induced reactogenic side effects to production of the pro-inflammatory cytokine interleukin-1β (IL-1β) in humans.
80 23056330 We found that an rVSV vaccine induced local and systemic production of IL-1β in vivo, and that accumulation of IL-1β correlated with acute pathology after rVSV immunization. rVSV-induced pathology was reduced in mice deficient in the IL-1 receptor Type I, but the IL-1R-/- mice were fully protected from lethal rechallenge with a high dose of VSV.
81 23056330 The amount of IL-1β detected in mice deficient in either caspase-1 or the inflammasome adaptor molecule ASC after rVSV immunization was not significantly different than that produced by wild type animals, and caspase-1-/- and ASC-/- mice were only partially protected from rVSV-induced pathology.
82 23056330 Those data support the idea that some of the IL-1β expressed in vivo in response to VSV may be activated by a caspase-1 and ASC-independent mechanism.
83 23056330 Together these results suggest that rVSV vectors engineered to suppress the induction of IL-1β, or signaling through the IL-1R would be less reactogenic in vivo, but would retain their immunogenicity and protective capacity.
84 23904458 Rectal swabs from 79 MSM (with and without C. trachomatis, HIV, and cART use) who reported a history of receptive anal sex were analyzed for neutrophil activation (measured by myeloperoxidase [MPO]), mucosal leakage (measured by albumin and alpha-2-macroglobulin), and proinflammatory and anti-inflammatory cytokines.
85 23904458 Interleukin 8 (IL-8) was found to correlate with MPO, and MPO correlated with markers of mucosal damage.
86 23904458 In HIV-negative participants, men with C. trachomatis infection had lower concentrations of monocyte chemotactic protein 1 (MCP-1), IL-1α, and IL-1 receptor antagonist (IL-1RA) than men without rectal C. trachomatis infection (P = 0.005, 0.007, and 0.07, respectively).
87 23904458 In participants with rectal C. trachomatis infection, those who were HIV negative had lower median concentrations of IL-8 and IL-1α than those with HIV (P = 0.05 and 0.06, respectively).
88 23904458 The slope of the regression line between MPO and IL-8 was reduced in participants with rectal C. trachomatis infection.
89 24614655 Interleukin-1 receptor but not Toll-like receptor 2 is essential for MyD88-dependent Th17 immunity to Coccidioides infection.
90 24614655 Interleukin-17A (IL-17A)-producing CD4(+) T helper (Th17) cells have been shown to be essential for defense against pulmonary infection with Coccidioides species.
91 24614655 Here, we report that both MyD88(-/-) and Card9(-/-) mice immunized with a live, attenuated vaccine also fail to acquire protective immunity to this respiratory disease.
92 24614655 Like Card9(-/-) mice, vaccinated MyD88(-/-) mice revealed a significant reduction in numbers of both Th17 and Th1 cells in their lungs after Coccidioides infection.
93 24614655 Both Toll-like receptor 2 (TLR2) and IL-1 receptor type 1 (IL-1r1) upstream of MyD88 have been implicated in Th17 cell differentiation.
94 24614655 Surprisingly, vaccinated TLR2(-/-) and wild-type (WT) mice showed similar outcomes after pulmonary infection with Coccidioides, while vaccinated IL-1r1(-/-) mice revealed a significant reduction in the number of Th17 cells in their infected lungs compared to WT mice.
95 24614655 Our data also reveal that the numbers of Th17 cells were reduced in IL-1r1(-/-) mice to a lesser extent than in MyD88(-/-) mice, raising the possibility that other TLRs are involved in MyD88-dependent Th17 immunity to coccidioidomycosis.
96 25389373 Type I interferon signaling contributes to the bias that Toll-like receptor 4 exhibits for signaling mediated by the adaptor protein TRIF.
97 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).
98 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.
99 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.
100 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.
101 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.
102 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.
103 25555811 As a pivotal signaling mediator of toll-like receptor (TLR) and interleukin (IL)-1 receptor (IL-1R) signaling cascades, the IL-1R-associated kinase 4 (IRAK4) is engaged in the activation of host immunity.
104 25786687 Cholera toxin, and the related nontoxic adjuvants mmCT and dmLT, promote human Th17 responses via cyclic AMP-protein kinase A and inflammasome-dependent IL-1 signaling.
105 25786687 CT, mmCT, and dmLT strongly enhanced IL-17A and to a lesser extent IL-13 responses, but had little effect on IFN-γ production or cell proliferation.
106 25786687 Intracellular cytokine staining revealed that the enhanced IL-17A production was largely confined to CD4(+) T cells and coculture experiments showed that the IL-17A promotion was effectively induced by adjuvant-treated monocytes.
107 25786687 Thus, inhibition of cAMP-dependent protein kinase A was abolished, and stimulation with a cAMP analog mimicked the adjuvant effect.
108 25786687 Furthermore, CT, mmCT, and dmLT induced IL-1β production and caspase-1 activation in monocytes, which was associated with increased expression of key proinflammatory and inflammasome-related genes, including NLRP1, NLRP3, and NLRC4.
109 25786687 Inflammasome inhibition with a specific caspase-1 inhibitor, or blocking of IL-1 signaling by IL-1 receptor antagonist, abrogated the Th17-promoting effect.
110 25786687 We conclude that CT, mmCT, and dmLT promote human Th17 responses via cAMP-dependent protein kinase A and caspase-1/inflammasome-dependent IL-1 signaling.
