The Human RVB Complex Is Required for Efficient Transcription of Type I Interferon-Stimulated Genes

The Paf1 complex is required for efficient transcription elongation by RNA polymerase I.

Regulation of RNA polymerase I (Pol I) transcription is critical for controlling ribosome synthesis. Most previous investigations into Pol I transcription regulation have focused on transcription initiation. To date, the factors involved in the control of Pol I transcription elongation are poorly understood. The Paf1 complex (Paf1C) is a well-defined factor that influences polymerase II (Pol II...

Virus Multiplicity of Infection Affects Type I Interferon Subtype Induction Profiles and Interferon-Stimulated Genes.

UNLABELLED Type I interferons (IFNs) are induced upon viral infection and important mediators of innate immunity. While there is 1 beta interferon (IFN-β) protein, there are 12 different IFN-α subtypes. It has been reported extensively that different viruses induce distinct patterns of IFN subtypes, but it has not been previously shown how the viral multiplicity of infection (MOI) can affect IF...

Human T Lymphotropic Virus Type I (HTLV-I) is a Risk Factor for Coronary Artery Disease

Estrous cycle stage-dependent manner of type I interferon-stimulated genes induction in the bovine endometrium

Interferon tau (IFN-τ) is a ruminant-specific type I IFN secreted by a conceptus before its attachment to the uterus. IFN-τ induces the expression of IFN-stimulated genes (ISGs) via the type I IFN receptor (IFNAR), which is composed of IFNAR1 and IFNAR2 subunits in the endometrium. However, expression patterns of IFNARs during the estrous cycle have not been reported. We hypothesized that the r...

Type I interferon signaling is required for activation of the inflammasome during Francisella infection

Francisella tularensis is a pathogenic bacterium whose virulence is linked to its ability to replicate within the host cell cytosol. Entry into the macrophage cytosol activates a host-protective multimolecular complex called the inflammasome to release the proinflammatory cytokines interleukin (IL)-1beta and -18 and trigger caspase-1-dependent cell death. In this study, we show that cytosolic F...
