Transcriptional profiles of Ad-F7 transduced macrophages treated with anti-IFNAR2 antibody or control isotype (IgG)

Project description:Determine the role of interferons in the transcriptional profile of Ad-F7 transduced primary human macrophages using neutralizing antibody for the type I IFN receptor (IFNAR2). Primary human macrophage preparations were transduced with Ad-GFP or Ad-F7 and treated with control isotype (IgG) or neutralizing antibody for the type I IFN receptor (IFNAR2). RNA was collected 24 hours later and subjected to microarray analysis. Data represents the average of 5 donors.

Transcriptional profiles of Ad-F3 and Ad-F7 transduced macrophages

Project description:To identify genes that may regulate distinct or overlapping functions of IRF-3 and IRF-7, primary human macrophage preparations were transduced with adenoviral vectors: Ad-GFP (control), Ad-F3 (expressing the active form of IRF-3, IRF-3 5D), or Ad-F7 (expressing the active form of IRF-7, IRF-7 D247-467) and evaluated by microarray analysis. RNA was collected 24 hours post-transduction with Ad-GFP, Ad-F3 and Ad-F7 and subjected to microarray analysis. Submited tables show the average of 7 donors.

Structural basis of a novel Interferon b signaling axis mediated via the ifnar1 receptor

Project description:Type I interferons (IFNs) are a family of cytokines that play an important role in regulating immune responses to pathogens and tumors and are used therapeutically. All IFNs are considered to signal via the heterodimeric IFNAR1-IFNAR2 complex, yet some subtypes such as IFN? can exhibit distinct functional properties, although the molecular basis of this is unclear. Here we demonstrate IFN uniquely and specifically ligates to IFNAR1 in an IFNAR2-independent manner and provide the structural basis of the IFNAR1-IFN interaction. We show that the IFNAR1-IFN complex transduces signals to modulate the expression of a set of genes independently of IFNAR2. Moreover, we show the in vivo importance of the IFNAR1-IFN signaling axis in a murine model of LPS-induced septic shock. Thus, we provide a molecular basis for understanding specific functions of IFN?. Interferon b induced gene expression in peritoneal exudate cells was measured 3hr post intra-peritoneal injection of 10,000IU/ml of interferon beta or saline into wildtype and Ifnar2-/- mice. Three independant experiments were performed for each treatment in both genotypes using different mice for each sample.

Synthetic mimetics assigned a major role to IFNAR2 in type I Interferon signaling

Project description:Type I Interferons (IFNs) are potent inhibitors of viral replication. Here, we reformatted the natural murine and human type I Interferon-α/β receptors IFNAR1 and IFNAR2 into fully synthetic biological switches. The transmembrane and intracellular domains of natural IFNAR1 and IFNAR2 were conserved, whereas the extracellular domains were exchanged by nanobodies directed against the fluorescent proteins Green fluorescent protein (GFP) and mCherry. Using this approach, multimeric single-binding GFP-mCherry ligands induced synthetic IFNAR1/IFNAR2 receptor complexes and initiated STAT1/2 mediated signal transduction via Jak1 and Tyk2. Homodimeric GFP and mCherry ligands showed that IFNAR2 but not IFNAR1 homodimers were sufficient to induce sustained STAT1/2 signaling. Transcriptome analysis revealed that synthetic murine type I IFN signaling was highly comparable to IFNα4 signaling and resulted in efficient elimination of vesicular stomatitis virus (VSV) in a cell culture based viral infection model using MC57 cells stimulated with synthetic type IFN ligands. Using intracellular deletion variants and point mutations, Y510 and Y335 in murine IFNAR2 were verified as unique phosphorylation sites for STAT1/2 activation, whereas the other tyrosine residues in IFNAR1 and IFNAR2 were not involved in STAT1/2 phosphorylation. Comparative analysis of synthetic human IFNARs supporting this finding. In summary, our data showed that synthetic type I IFN signal transduction is originating from IFNAR2 rather than IFNAR1.
