Stochastic Expression of the Interferon-β Gene
Virus infection of mammalian cells induces the production of high levels of type I interferons (IFNα and β), cytokines that orchestrate antiviral innate and adaptive immunity. Previous studies have shown that only a fraction of the infected cells produce IFN. However, the mechanisms responsible for this stochastic expression are poorly understood. Here we report an in depth analysis of IFN-expr...
متن کاملCardiac glycosides are potent inhibitors of interferon-β gene expression
Here we report that bufalin and other cardiac glycoside inhibitors of the sodium-potassium ATPase (sodium pump) potently inhibit the induction of the interferon-β (IFNβ) gene by virus, double-stranded RNA or double-stranded DNA. Cardiac glycosides increase the intracellular sodium concentration, which appears to inhibit the ATPase activity of the RNA sensor RIG-I, an essential and early compone...
متن کاملNovel interferon-β-induced gene expression in peripheral blood cells.
Type I IFNs are used for treating viral, neoplastic, and inflammatory disorders. The protein products encoded by IFN-stimulated genes (ISGs) likely mediate clinical effects of IFN in patients. Macroarray assays, used for studying ISG induction in IFN-treated patients, comprise genes identified predominantly through analysis of long-term cell lines. To discover genes induced selectively by IFN-β...
متن کاملCLONING AND EXPRESSION OF A HUMAN INTERFERON a2 GENE IN E. COLI
The plasmid pALCA1SIFN containing cDNA that encodes the human interferon a-2b was obtained from the ATCC(no. 531667). In this system the expression of the gene is under the control of an alcA promoter. alcA p is a specific promoter for expression of different genes in Aspergillusfilamentous. In this plasmid the coding region of IFN?-2b is preceded by the coding region of a synthetic signal ...
متن کاملCloning and high level expression of bovine interferon gamma gene in eukaryotic cells (COS-7)
Interferon gamma (IFN-γ) is one of the key cytokines in defining T helper 1 lymphocyte immuneresponses. In this study, the bovine IFN-γ gene was cloned from spleen tissue RNA using the reversetranscription-polymerase chain reaction (RT-PCR). IFN-γ cDNA was sub-cloned and expressed inmammalian expression plasmid (pcDNA3.1(+)) under the control of the human cytomegalovirus (CMV)promoter. The pred...
