Plasmacytoid dendritic cells (pDCs) respond to viral infection by production of alpha interferon (IFN-α), proinflammatory cytokines, and cell differentiation. The elimination of hepatitis C virus (HCV) in more than 50% of chronically infected patients by treatment with IFN-α suggests that pDCs can play an important role in the control of HCV infection. pDCs exposed to HCV-infected hepatoma cell...
Porphyromonas gingivalis (P. gingivalis) can trigger an inflammatory condition leading to the destruction of periodontal tissues. However P. gingivalis LPS and its fimbriae (FimA) play different roles compared with the live bacteria in the context of intracellular molecule induction and cytokine secretion. To elucidate whether this difference results from different signaling pathways in host im...
BACKGROUND In response to viral infection, the innate immune system recognizes viral nucleic acids and then induces production of proinflammatory cytokines and type I interferons (IFNs). Toll-like receptor 7 (TLR7) and TLR9 detect viral RNA and DNA, respectively, in endosomal compartments, leading to the activation of nuclear factor kappaB (NF-kappaB) and IFN regulatory factors (IRFs) in plasma...
Vaccines are beneficial and universal tools to prevent infectious disease. Thus, safety of vaccines is strictly evaluated in the preclinical phase of trials and every vaccine batch must be tested by the National Control Laboratories according to the guidelines published by each country. Despite many vaccine production platforms and methods, animal testing for safety evaluation is unchanged thus...
We used next-generation RNA sequencing (RNA-Seq) technology on the whole transcriptome to identify genes whose expression is consistently affected by obesity across multiple arteries. Specifically, we examined transcriptional profiles of the iliac artery as well as the feed artery, first, second, and third branch order arterioles in the soleus, gastrocnemius, and diaphragm muscles from obese Ot...

Transcriptional activation of the interferon-beta (IFN-beta) gene requires assembly of an enhanceosome containing ATF-2/c-Jun, IRF-3/IRF-7, and NFkappaB. These factors bind cooperatively to the IFN-beta enhancer and recruit coactivators and chromatin-remodeling proteins to the IFN-beta promoter. We describe here a crystal structure of the DNA-binding domains of IRF-3, IRF-7, and NFkappaB, bound...
Transcriptional activation of the IFN-beta gene by virus infection requires the cooperative assembly of an enhanceosome. We report that the stochastic and monoallelic expression of the IFN-beta gene depends on interchromosomal associations with three identified distinct genetic loci that could mediate binding of the limiting transcription factor NF-kappaB to the IFN-beta enhancer, thus triggeri...
