The discriminative capacity of soluble Toll-like receptor (sTLR)2 and sTLR4 in inflammatory diseases
Toll-like receptor (TLR) 2 and TLR4 play important roles in the early, innate immune response to microbial challenge. TLR2 is preferentially involved in the inflammatory response to lipoteichoic acid, lipopeptides, and glycans from a variety of microbes, whereas TLR4 is essential for a complete response to LPSs. We report here that TLR2 transduces the response to phenol-soluble modulin, a facto...
Agonists of Toll-like receptors (TLRs) are potent activators of the innate immune system and hold promise as vaccine adjuvant and for anticancer immunotherapy. Unfortunately, in soluble form they readily enter systemic circulation and cause systemic inflammatory toxicity. Here we demonstrate that by covalent ligation of a small-molecule imidazoquinoline-based TLR7/8 agonist to 50-nm-sized degra...
Invariant natural killer T (iNKT) cells are a subset of nonconventional T cells recognizing endogenous and/or exogenous glycolipid antigens in the context of CD1d molecules. It remains unclear whether innate stimuli can modify the profile of endogenous lipids recognized by iNKT cells on the surface of antigen-presenting cells (APCs). We report that activation of human APCs by Toll-like receptor...
toll-like receptor 4 (tlr4), considered one of the most important tlr, recognizes lipopolysaccharide of gram-negative bacteria. recognition of ligands by tlrs induces signaling pathways resulting in activation of transcriptional factors such as nf-κb which are involved in the expression of inflammatory cytokines and chemokines. to prevent an inappropriate immune response, a complex ...
the innate immune system recognizes the presence of bacterial products through the expression of a family of membrane receptors known as toll-like receptors (tlrs). polymorphisms in tlrs have been shown to be associated with increased susceptibility to diseases such as inflammatory bowel disease. the aim of this study was to determine whether there was a correlation between polymorphisms of tlr...
Toll-like receptor (TLR) signaling plays a critical role in innate and adaptive immune responses and must be tightly controlled. TLR4 uses LPS binding protein, MD-2, and CD14 as accessories to respond to LPS. We therefore investigated the presence of an analagous soluble cofactor that might assist in the recruitment of CpG oligonucleotides (CpG-ODNs) to TLR9. We report the identification of gra...
Innate immunity is the first-line defense against pathogens and relies on phagocytes, soluble components, and cell-surface and cytosolic pattern recognition receptors. Despite using hard-wired receptors and signaling pathways, the innate immune response demonstrates surprising specificity to different pathogens. We determined how combinatorial use of innate immune defense mechanisms defines the...
