Interferon regulatory factor 3-dependent responses to lipopolysaccharide
The synthesis of interferon (IFN)β and IFN-inducible factors elicited by lipopolysaccharide (LPS) depends on the transcriptional activity of interferon regulatory factor (IRF)-3 downstream of Toll-like receptor (TLR)4. To examine the ability of human newborns to mount TLR4-mediated IRF-3-dependent responses, we analyzed the pattern of genes expressed upon addition of LPS to cord blood or cord b...
متن کاملRole of interferon regulatory factor 3 in type I interferon responses in rotavirus-infected dendritic cells and fibroblasts.
The main pathway for the induction of type I interferons (IFN) by viruses is through the recognition of viral RNA by cytosolic receptors and the subsequent activation of interferon regulatory factor 3 (IRF-3), which drives IFN-alpha/beta transcription. In addition to their role in inducing an antiviral state, type I IFN also play a role in modulating adaptive immune responses, in part via their...
متن کاملPrimary activation of interferon A and interferon B gene transcription by interferon regulatory factor 3.
The family of interferon (IFN) regulatory factors (IRFs) encodes DNA-binding transcription factors, some of which function as modulators of virus-induced signaling. The IRF-3 gene is constitutively expressed in many tissues and cell types, and neither virus infection nor IFN treatment enhances its transcription. In infected cells, however, IRF-3 protein is phosphorylated at the carboxyl terminu...
متن کاملInterferon-γ Upregulates Expression of IFP35 Gene in HeLa Cells via Interferon Regulatory Factor-1
BACKGROUND Interferon-induced 35-kDa protein (IFP35) plays important roles in antiviral defense and the progression of some skin cancer diseases. It can be induced by interferon-γ (IFN-γ) in multiple human cells. However, the mechanisms by which IFN-γ contributes to IFP35 induction remain to be elucidated. METHODS/PRINCIPAL FINDINGS We identified the transcription start sites of IFP35 by 5' r...
متن کاملInterferon Regulatory Factor (Irf)-1 and Irf-2 Regulate Interferon γ–Dependent Cyclooxygenase 2 Expression
Cyclooxygenases (Cox) are rate-limiting enzymes that initiate the conversion of arachidonic acid to prostanoids. Cox-2 is the inducible isoform that is upregulated by proinflammatory agents, initiating many prostanoid-mediated pathological aspects of inflammation. In this study, we demonstrate that interferon (IFN)-gamma alone or in synergy with lipopolysaccharide (LPS) or interleukin 1alpha in...
