Functions as sorting adapter in LPS-TLR4 signaling to regulate the MYD88-independent pathway during the innate immune response to LPS. Physically bridges TLR4 and TICAM1 and functionally transmits LPS-TRL4 signal to TICAM1; signaling is proposed to occur in early endosomes after endocytosis of TLR4. May also be involved in IL1-triggered NF-kappa-B activation, functioning upstream of IRAK1, IRAK2, TRAF6, and IKBKB; however, reports are controversial. Involved in IL-18 signaling and is proposed to function as a sorting adaptor for MYD88 in IL-18 signaling during adaptive immune response.
BACKGROUND: Excessive iodine intake and viral infection are recognized as both critical factors associated with autoimmune thyroid diseases. Toll-like receptors (TLRs) have been reported to play an important role in autoimmune and inflammatory disorders. In this study, we aimed to clarify the possible mechanism of TLR3 involved in polyinosine-polycytidylic acid (poly(I:C)) promoting excessive iodine intake induced thyroiditis in non-obese diabetic (NOD) mice. METHODS: Both NOD and BALB/c mice were randomly assigned to four groups: control group (n = 5), high iodine intake (HI) group (n = 7), poly(I:C) group (n = 7) and combination of excessive iodine and poly(I:C) injection (HIP) group (n = 7 ...

TLR signaling is mediated by the recruitment of distinct combinations of adaptor molecules to the cytoplasmic TIR domain of each TLR. Distribution and localization of the adaptor molecules are important factors controlling TLR-mediated signaling. TIRAP/Mal was found to be associated with the plasma membrane via a phosphatidylinositol 4,5-biphosphate-binding domain and facilitates MyD88 delivery to activated TLR4 (22). Also, myristoylation of TICAM-2/TRAM targets it to the plasma membrane and the Golgi apparatus, where it colocalizes with TLR4 (23). Thus, the role of these adaptor proteins other than TICAM-1 has been clearly demonstrated; TIRAP/Mal and TICAM-2/TRAM mainly function as bridges between TLR4 and the signaling adaptors, whereas MyD88 restricts its localization by TIRAP to assemble signal molecules around the TLR4 complex (9, 10, 24, 25). In this study we demonstrated that TICAM-1/TRIF delivers a signal in a unique fashion distinct from that of MyD88.. This is the first study to ...
Receptor-mediated detection of pathogen-derived nucleic acids assists in protecting the host genome from invading foreign genetic material. Retinoic acid-inducible protein I (RIG-I) recognizes a specific set of RNA viruses (Flaviviridae, Paramyxoviridae, Orthomyxoviridae, and Rhabdoviridae) (1-3), whereas a second member of this protein family, melanoma differentiation-associated gene 5 (MDA-5), is responsible for the antiviral defense against a reciprocal set of RNA viruses (Picornaviridae) (3). The four members of the Toll-like receptor (TLR) family (TLR3, TLR7, TLR8, and TLR9) involved in viral nucleic acid recognition are located in the endosomal membrane. TLRs are largely dispensable for effective antiviral defense, whereas the two cytosolic helicases MDA-5 and RIG-I (1) are essential for controlling viral infection.. The molecular characteristic of double-strandedness seems to allow for the distinction of self and nonself RNA. In the endosome, long double-stranded RNA (dsRNA) and its ...

Three experiments were performed to study the effects of immune challenge on the rewarding properties of opiates. Intraperitoneal injection of polyinosinic-polycytidylic acid (Poly I: C, 1 mg/kg) was used to trigger an immune challenge. Conditioned place preference (CPP) in rats trained with alternating subcutaneous injections of morphine (5 mg/kg) and saline was used to assess the rewarding effect of morphine. Poly I: C administered before CPP training had no effects on CPP acquisition. Poly I: C administered during CPP training enhanced CPP acquisition. Poly I: C administered after morphine-induced CPP acquisition retarded CPP extinction. These results show that the immune challenge by Poly I: C augmented morphine CPP in rats depending on the onset time of the challenge. The findings suggest that immune challenge may enhance the rewarding properties of opiates. Behavioural Pharmacology 21: 369-373 (C) 2010 Wolters Kluwer Health , Lippincott Williams & Wilkins. ...
In response to ligand binding to the Toll-like receptor 4 (TLR4) and myeloid differentiation-2 (MD-2) receptor complex, two major signaling pathways are activated that involve different adaptor proteins. One pathway depends on myeloid differentiation marker 88 (MyD88), which elicits proinflammatory responses, whereas the other depends on Toll-IL-1 receptor (TIR) domain-containing adaptor inducing interferon-β (TRIF), which elicits type I interferon production. Here, we showed that the TLR4 agonist and vaccine adjuvant CRX-547, a member of the aminoalkyl glucosaminide 4-phosphate (AGP) class of synthetic lipid A mimetics, displayed TRIF-selective signaling in human cells, which was dependent on a minor structural modification to the carboxyl bioisostere corresponding to the 1-phosphate group on most lipid A types. CRX-547 stimulated little or no activation of MyD88-dependent signaling molecules or cytokines, whereas its ability to activate the TRIF-dependent pathway was similar to that of a ...
Bacterial and viral RNA are potent stimulators of the innate immune system, leading to immune cell activation and type I IFN production (Takeuchi and Akira, 2010). Generally, RNA recognition takes place in the endosome or cytoplasm and is mediated by Toll-like receptors (TLRs) and retinoic acid inducible gene I (RIG-I)-like helicases, respectively. In more detail, TLR3 recognizes double-stranded viral RNA and mRNA, whereas TLR7 and TLR8 sense viral or bacterial single-stranded RNA and short interfering RNA (siRNA; Blasius and Beutler, 2010). In contrast, cytoplasmic detection of viral and bacterial RNA is mediated by the RNA helicases RIG-I and MDA5 (melanoma differentiation-associated gene 5; Kato et al., 2006; Monroe et al., 2009).. Of note, RNA modifications in ribosomal RNA and transfer RNA (tRNA) such as 2′-O-methylation, base methylation (e.g., m5C, m6A, and m5U), and the occurrence of pseudouridine negatively modify the immunostimulatory potential of synthetic RNA (Karikó et al., ...
Takashima K., Oshiumi H., Takaki H., Matsumoto M., Seya T.. MDA5 is a cytoplasmic viral double-stranded RNA (dsRNA) sensor and triggers type I interferon (IFN) production. MDA5 assembles along viral dsRNA, leading to the formation of an MDA5 filament required for activating the MAVS adaptor. A recent study has revealed that PP1α and PP1γ phosphatases are responsible for dephosphorylating MDA5 and are essential for its activation. Here, we identified RIO kinase 3 (RIOK3) as a protein kinase that phosphorylates the MDA5 C-terminal region. RIOK3 knockout strongly enhanced type I IFN and IFN-inducible gene expression following measles virus infection. Conversely, the ectopic expression of RIOK3 or a phosphomimetic MDA5-S828D mutation attenuated MDA5-mediated signaling. Moreover, RIOK3-mediated MDA5 phosphorylation impaired MDA5 multimer formation, indicating that MDA5 C-terminal phosphorylation interferes with MDA5 filament formation and suppresses its signaling. Our data revealed a regulatory ...
This Bovine Toll-like receptor 3 (TLR3) ELISA Kit employs a two-site sandwich ELISA to quantitate TLR3.,TLR3; CD283;,TLR 3 is a member of the Toll-like receptor family of pattern recognition receptors of the innate immune system. Discovered in 2001,TLR3 recognizes double-stranded RNA, a form of genetic information carried by some viruses such as reoviruses. Upon recognition, TLR 3 induces the activation of NF-kB to increase production of type I interferons which signal other cells to increase their antiviral defenses. Double-stranded RNA is also recognised by the cytoplasmic receptors RIG-I and MDA-5.The structure of TLR3 was reported in June 2005 by researchers at The Scripps Research Institute. TLR3 forms a large horseshoe shape that contacts with a neighboring horseshoe, forming a

Mammalian TLRs play a central role in innate immunity by mediating recognition of pathogen-associated microbial patterns. Human polymorphisms in TLR2 and TLR4 are associated, respectively, with increased susceptibility to S. aureus infections (9) and LPS hyporesponsiveness (12) underscoring the importance of intact PAMP recognition systems in human health. In addition to immune functions, invertebrate TLRs have been shown to act during development and in cell to cell interactions (31, 32, 33). Further complexity in understanding TLR biology arises from the recognition that some TLRs act as coreceptors (e.g., TLR1, TLR6) with other TLRs (e.g., TLR2) and can promote or inhibit cellular responsiveness to activating ligands (26, 34). To identify settings both within the immune system and throughout the body in which TLRs may regulate important biological processes, we initiated a study of the expression of human TLRs.. Consistent with their roles in immune surveillance, TLR mRNAs are expressed at ...

Y1 - 2006/8. N2 - Toll-like receptors (TLRs) form a family of pattern recognition receptors that have emerged as key mediators of innate immunity. These receptors sense invading microbes and initiate the immune response. TLR-mediated inflammation is an important pathogenic link between innate immunity and a diverse panel of clinical disorders. Among the processes in which TLRs play a role are cardiovascular disorders such as cardiac ischaemia, coronary artery disease, ventricular remodelling, cancer angiogenesis or transplant rejection. From these, many important opportunities for disease modification through TLR signalling manipulation can be imagined. Their role as potential targets for therapeutic intervention is just beginning to be appreciated and this article reviews the current status of these ...
Pattern recognition underpins innate immunity; the accurate identification of danger, including infection, injury, or tumor, is key to an appropriately targeted immune response. Pathogen detection is increasingly well defined mechanistically, but the discrimination of endogenous inflammatory triggers remains unclear. Tenascin-C, a matrix protein induced upon tissue damage and expressed by tumors, activates toll-like receptor 4 (TLR4)-mediated sterile inflammation. Here we map three sites within tenascin-C that directly and cooperatively interact with TLR4. We also identify a conserved inflammatory epitope in related proteins from diverse families, and demonstrate that its presence targets molecules for TLR detection, while its absence enables escape of innate immune surveillance. These data reveal a unique molecular code that defines endogenous proteins as inflammatory stimuli by marking them for recognition by TLRs.

POSTER 88 - A SCREEN FOR NOVEL GENES INVOLVED IN TLR SIGNALING Jiang ZF, Du X, Shamel L, Beutler B The Scripps Research Institute, La Jolla, United States Toll-like receptors (TLRs) play essential roles in inflammation and innate immunity. Individual TLRs respond to specific molecules of microbial origin. TLR4 has been identified as the sensor for lipopolysaccharide (LPS), a molecular component of Gram-negative bacteria. TLR2 responds to molecules derived from mycobacteria, yeast, and Gram-positive bacteria. TLR5 and TLR9 recognize bacterial flagellins, and unmethylated DNA bearing CpG motifs, while TLR3 and TLR7 recognize viral double-stranded RNA (dsRNA) and single-stranded RNA (ssRNA), respectively. While many of the molecules involved in TLR-mediated signaling have been identified, others remain obscure, and numerous questions surround the sensing mechanism itself. ENU mutagenesis has been used to identify novel genes in the process by screening for ENU-caused germline mutants that are ...
Mitochondria, known to share many common features with prokaryotic cells, accumulate several endogenous ligands of the pattern-recognition Toll-like receptor 4 (TLR4), such as the heat shock proteins (Hsp) 70 and 60. TLR4 specifically recognises and responds to LPS of Gram-negative bacteria and participates in both autoimmune reactions and tissue regeneration due to its ability to recognise endogenous ligands. In the present study we show that mitochondria extracts obtained from hydrogen peroxide-dysfunctionalised cells induce a pro-inflammatory response in human THP-1 myeloid leukaemia cells. This inflammatory response was similar to that caused by LPS and much stronger than that induced by the extracts of normal mitochondria. Such reactions include activation of stress-adaptation hypoxia-inducible factor 1 alpha (HIF-1?) and expression/release of the pro-inflammatory cytokines IL-6 and TNF-?. Pre-treatment of THP-1 myeloid macrophages with TLR4-neutralising antibody before exposure to ...
The innate immune system detects highly conserved, relatively invariant structural motifs of pathogens. Toll-like receptors (TLRs) have been identified as the primary innate immune receptors. TLRs distinguish between different patterns of pathogens and activate a rapid innate immune response; however, TLRs can also be activated by host-derived molecules. In addition to being expressed in immune cells, TLRs are expressed in other tissues, such as those of the cardiovascular system. TLRs could, therefore, be a key link between cardiovascular disease development and the immune system. Indeed, evidence that TLR activation contributes to the development and progression of atherosclerosis, cardiac dysfunction in sepsis, and congestive heart failure, is convincing. Although much has been learned about TLR activation in cellular components of the cardiovascular system, the role individual TLR family members have in the pathophysiology of cardiovascular diseases and hence in clinical practice remains to be
to circumvent innate immunity was demonstrated (Cirl et al. 2008, Nature Medicine 14, 399-406). This involves a bacterial TIR domain-containing protein (Tcp) that is secreted by bacterial pathogens and inhibits Toll-like receptor (TLR) signalling. ,p, Toll-like receptors have a central role in innate immunity. They recognise molecules from microbial pathogens and trigger an immune response through a signalling domain called TIR. Bacterial Tcps contain a TIR domain that mimics the TIR domain of Toll-like receptors. TLR signalling is interrupted when MyD88, a downstream component of TLR signalling, binds to the TIR domain of a bacterial Tcp instead of to the TIR domain of a Toll-like receptor. This way, secreted Tcps impair the release of cytokines and, subsequently, prevent an inflammatory response. ,p, Our data show that bacterial Tcps or the TIR domains contained in Tcps can be used to modulate cytokine responses of innate immune cells as is desirable in the treatment of autoimmune diseases. ...
Toll-like receptor 2 also known as TLR2 is a protein that in humans is encoded by the TLR2 gene. TLR2 has also been designated as CD282 (cluster of differentiation 282). TLR2 is one of the toll-like receptors and plays a role in the immune system. TLR2 is a membrane protein, a receptor, which is expressed on the surface of certain cells and recognizes foreign substances and passes on appropriate signals to the cells of the immune system. The protein encoded by this gene is a member of the Toll-like receptor (TLR) family, which plays a fundamental role in pathogen recognition and activation of innate immunity. TLRs are highly conserved from Drosophila to humans and share structural and functional similarities. They recognize pathogen-associated molecular patterns (PAMPs) that are expressed on infectious agents, and mediate the production of cytokines necessary for the development of effective immunity. The various TLRs exhibit different patterns of expression. This gene is expressed most ...
TAK-242 (resatorvid), a small molecule specific inhibitor of Toll-like receptor (TLR) 4 signaling, inhibits the production of lipopolysaccharide-induced inflammatory mediators by binding to the intracellular domain of TLR4. Previously, Cys747 in TLR4 was identified as the binding site of TAK-242. However, the mechanism by which TAK-242 inhibits TLR4 signaling after binding to TLR4 remains unknown. The present study demonstrated, using coimmunoprecipitation, that TAK-242 interferes with protein-protein interactions between TLR4 and its adaptor molecules. Among ten different human TLRs, TAK-242 selectively bound to TLR4. The time course of the inhibitory effect of TAK-242 on inflammatory mediator production corresponded to that of the binding of TAK-242 to TLR4. TAK-242 inhibited the association of TLR4 with TIR domain-containing adaptor protein (TIRAP) or TRIF-related adaptor molecule (TRAM) in HEK293 cells overexpressing TLR4, MD-2 and TIRAP or TRAM, respectively. TAK-242 inhibited the ...

Abstract:. Computational approaches to the dynamics and activation mechanism of Toll-like receptor 4. Topic:. Toll-like receptors (TLRs) are pattern recognition receptors involved in innate immunity. In particular, TLR4 binds to lipopolysaccharides (LPS), a membrane constituent of Gram-negative bacteria and, together with MD-2 protein, forms a heterodimeric complex which leads to the activation of the innate immune system response. TLR4 activation has been associated with certain autoimmune diseases, noninfectious inflammatory disorders, and neuropathic pain, suggesting a wide range of possible clinical settings for the application of TLR4 antagonists, while TLR4 agonists would be useful as adjuvants in vaccine development and in cancer immunotherapy. Specific molecular features of extracellular, transmembrane, and cytoplasmic domains of TLR4 are crucial for coordinating the complex innate immune signaling pathway. Although structural and biochemical data is currently available for the ...
As part of the PANACEA (for Pharmacological Augmentation of Nonspecific Anti-pathogen Cellular Enzymes and Activities) project, researchers from MIT Lincoln Laboratory have developed and demonstrated a novel broad-spectrum antiviral approach, called DRACO (for Double-stranded RNA [dsRNA] Activated Caspase Oligomerizer). DRACO selectively induces apoptosis, or cell suicide, in cells containing any viral dsRNA, rapidly killing infected cells without harming uninfected cells. As a result, DRACO should be effective against virtually all viruses, rapidly terminating a viral infection while minimizing the impact on the patient ...
