Interferon regulatory factor 7 is induced by Epstein-Barr virus latent membrane protein 1.
Infection by Epstein-Barr virus (EBV) generates several types of latency with different profiles of gene expression but with expression of Epstein-Barr nuclear antigen 1 (EBNA-1) in common. The BamHI Q promoter (Qp) is used for the transcription of EBNA-1 mRNA in type I latency, which is an EBV infection state exemplified by Burkitt's lymphoma (BL). However, Qp is inactive in type III latency, ...
متن کاملInterferon regulatory factor 7-mediated responses are defective in cord blood plasmacytoid dendritic cells.
Plasmacytoid dendritic cells (pDC) are specialized in massive production of type I interferons (IFN) upon viral infections. Activation of IFN regulatory factor (IRF)-7 is critically required for the synthesis of type I IFN in pDC. IRF-7 is highly expressed by resting pDC and translocates into the nucleus to initiate type I IFN transcription. In a previous work, we observed an impaired IFN-alpha...
متن کاملRole of interferon regulatory factor 7 in T cell responses during acute lymphocytic choriomeningitis virus infection.
Type I interferons (IFNs), predominantly IFN-α and -β, play critical roles in both innate and adaptive immune responses against viral infections. Interferon regulatory factor 7 (IRF7), a key innate immune molecule in the type I IFN signaling pathway, is essential for the type I IFN response to many viruses, including lymphocytic choriomeningitis virus (LCMV). Here, we show that although IRF7 kn...
متن کاملCloning and sequencing of rainbow trout (Oncorhynchus mykiss) interferon regulatory factor 7
Interferon regulatory factor 7 (IRF7) gene was cloned from a subtractive cDNA library constructed with mRNAs obtained from rainbow trout (Oncorhynchus mykiss) macrophage cell line (RTS-11). Using expressed sequence tag clones of submitted IRF7 amino acid sequences, specific primers were designed. Results showed that IRF7 cDNA contains an ORF of 1251 nucleotides that translates into a 416 resi...
متن کاملLambda interferon is the predominant interferon induced by influenza A virus infection in vivo.
The type I alpha/beta interferons (IFN-α/β) are known to play an important role in host defense against influenza A virus infection, but we have now discovered that the recently identified type III IFNs (IFN-λ) constitute the major response to intranasal infection with this virus. Type III IFNs were present at much higher levels than type I IFNs in the lungs of infected mice, and the enhanced s...
