interaction of cpg-oligodeoxynucleotides with toll like receptor 9 induces apoptosis and modulates metaloproteinase-2 activity in human intestinal epithelium
recent reports have indicated different effects of immunostimulatory sequences containing cpg-oligodeoxynucleotides (odn) on various immune cells. however, the exact role of cpg-odn in the human gut is unclear. in the present study, we assessed potential effects of cpg-odn on non lymphoid cell (intestinal epithelial cell line ht-29) on a dose-response and time-course basis. intestinal epithelia...
متن کاملSingle Molecule In Vivo Analysis of Toll-Like Receptor 9 and CpG DNA Interaction
Toll-like receptor 9 (TLR9) activates the innate immune system in response to oligonucleotides rich in CpG whereas DNA lacking CpG could inhibit its activation. However, the mechanism of how TLR9 interacts with nucleic acid and becomes activated in live cells is not well understood. Here, we report on the successful implementation of single molecule tools, constituting fluorescence correlation/...
متن کاملIn silico Study of Toll-Like Receptor 4 Binding Site of FimH from Uropathogenic Escherichia coli
Introduction : The innate immune system as the first line of defense against the pathogens recognizes pathogen-associated molecular patterns (PAMPs) by Toll-Like Receptors (TLRs). Interaction of bacterial PAMPs by TLRs results in activation of innate and acquired immunity. FimH adhesin, a minor component of type 1 fimbriae encoded by Uropathogenic Escherichia coli (UPEC) is a PAMP of TLR4 tha...
متن کاملImpaired toll-like receptor 9 expression in alveolar macrophages with no sensitivity to CpG DNA.
Unmethylated CpG motifs in bacterial DNA or synthetic oligodeoxynucleotides (ODN) potently stimulate the innate immune system, and they are recognized by Toll-like receptor 9 (TLR9), which is expressed by monocytes/macrophages, dendritic cells, and B cells. However, it is unknown whether alveolar macrophages (AMs) express functional TLR9. To clarify this, we analyzed mRNA expressions of TLRs in...
متن کاملTargeting toll-like receptor 9 with CpG oligodeoxynucleotides enhances tumor response to fractionated radiotherapy.
Synthetic oligodeoxynucleotides containing unmethylated CpG motifs detected by Toll-like receptor 9 of dendritic cells and B cells have potent immunomodulatory effects. CpG oligodeoxynucleotides induce cytokines, activate natural killer cells, and elicit T-cell responses leading to antitumor effects, including improved efficacy of chemotherapeutic agents and, as we reported recently, synergy be...
