Molecular mechanisms of induction and maintenance of endotoxin tolerance are incompletely understood, particularly with regard to the impact of endotoxin tolerization on signalosome assembly, activation of adaptor-kinase modules, and expression of negative regulators of TLR signaling in human cells. In this study, we examined LPS-mediated activation of MyD88-dependent and Toll-IL-1R-containing adaptor inducing IFN-beta (TRIF)-dependent pathways emanating from TLR4 and expression of negative regulators of TLR signaling in control and endotoxin-tolerant human monocytes. Endotoxin tolerization suppressed LPS-inducible TLR4-TRIF and TRIF-TANK binding kinase (TBK)1 associations, induction of TBK1 kinase activity, activation of IFN regulatory factor (IRF)-3, and expression of RANTES and IFN-beta. Tolerance-mediated dysregulation of the TLR4-TRIF-TBK1 signaling module was accompanied by increased levels of suppressor of IkappaB kinase-epsilon (SIKE) and sterile alpha and Armadillo motif-containing molecule (SARM). LPS-tolerant cells showed increased expression of negative regulators Toll-interacting protein (Tollip), suppressor of cytokine signaling (SOCS)-1, IL-1R-associated kinase-M, and SHIP-1, which correlated with reduced p38 phosphorylation, IkappaB-alpha degradation, and inhibited expression of TNF-alpha, IL-6, and IL-8. To examine functional consequences of increased expression of Tollip in LPS-tolerized cells, we overexpressed Tollip in 293/TLR4/MD-2 transfectants and observed blunted LPS-inducible activation of NF-kappaB and RANTES, while TNF-alpha responses were not affected. These data demonstrate dysregulation of TLR4-triggered MyD88- and TRIF-dependent signaling pathways and increased expression of negative regulators of TLR signaling in endotoxin-tolerant human monocytes."xsd:string |
