The Toll-like receptor (TLR)4 receptor complex, TLR4/MD-2, plays an important role in the inflammatory response against lipopolysaccharide, a ubiquitous membrane component in Gram-negative bacteria. Ligand recognition by TLR4 initiates multiple intracellular signaling pathways, leading to production of proinflammatory mediators and type I IFN. Ligand(More)
Epigenetic modifiers have fundamental roles in defining unique cellular identity through the establishment and maintenance of lineage-specific chromatin and methylation status. Several DNA modifications such as 5-hydroxymethylcytosine (5hmC) are catalysed by the ten eleven translocation (Tet) methylcytosine dioxygenase family members, and the roles of Tet(More)
CD8α(+) dendritic cells (DCs) are specialized at cross-presenting extracellular antigens on major histocompatibility complex (MHC) class I molecules to initiate cytotoxic T lymphocyte (CTL) responses; however, details of the mechanisms that regulate cross-presentation remain unknown. We found lower expression of the lectin family member Siglec-G in CD8α(+)(More)
Retinoic acid-inducible gene I (RIG-I) signaling is critical to host innate immune response against RNA virus infection. Numerous factors use different mechanisms to regulate RIG-I signaling. In this study, we report that STAT family member STAT4 promotes RIG-I-triggered type I IFN production in antiviral innate immunity. Silencing of STAT4 impaired IFN-β(More)
The DNA methyltransferase Dnmt3a has high expression in terminally differentiated macrophages; however, its role in innate immunity remains unknown. Here we report that deficiency in Dnmt3a selectively impaired the production of type I interferons triggered by pattern-recognition receptors (PRRs), but not that of the proinflammatory cytokines TNF and IL-6.(More)
This paper presents an efficient hybrid feedback feedforward (HFF) adaptive approximation-based control (AAC) strategy for a class of uncertain Euler-Lagrange systems. The control structure includes a proportional-derivative (PD) control term in the feedback loop and a radial-basis-function (RBF) neural network (NN) in the feedforward loop, which mimics the(More)
BACKGROUND As one of the most popular expression systems, recombinant protein expression in Pichia pastoris relies on the AOX1 promoter (P AOX1 ) which is strongly induced by methanol. However, the toxic and inflammatory nature of methanol restricts its application, especially in edible and medical products. Therefore, constructing a novel methanol-free(More)
Histone modifications play critical roles in the regulation of gene expression; however, their roles in the regulation of the innate response remain to be fully investigated. Using transcriptome analysis of mouse immature dendritic cells (DCs) and LPS-induced mature DCs, we identified that Ezh1 was the most upregulated histone methyltransferase during DC(More)
As a multifunctional nuclear protein, death domain-associated protein 6 (Daxx) regulates a wide range of biological processes, including cell apoptosis and gene transcription. However, the function of Daxx in innate immunity remains unclear. In our study, we show that Daxx is highly expressed in macrophages and localized in nucleus of macrophages. The(More)
