During viral infection, viral immediate-early (IE) genes encode regulatory proteins critical for the viral life cycle. Here we screened white spot syndrome virus (WSSV) IE genes with cycloheximide (CHX)-treated primary culture of crayfish hemocyte and a WSSV genome tiling microarray. Sixteen ORFs, including a known WSSV IE gene (ie1/wsv069), were identified(More)
The south coast of Laizhou Bay, in northeastern China, is a production area for halogenated flame retardants (HFR). In 2007, the authors measured serum concentrations of polybrominated diphenyl ethers (PBDEs) in Laizhou Bay residents. To assess the PBDE concentration trend, and determine the concentrations of the emerging flame retardants Dechlorane Plus(More)
Mouse beta defensin-1 (mBD-1) is a cationic 37-amino acid antimicrobial peptide with three conserved cysterine disulfied bonds. It exhibits a broad antimicrobial spectrum, but mBD-1 against Candida albicans (C. albicans) and Cryptococcus neoformans (C. neoformans) is poorly understood. This study describes the mBD-1 gene, the heterologous fusion expression(More)
MicroRNAs (miRNAs) are a class of small noncoding RNAs that function as regulators of gene expression. They play essential roles in various biological processes, such as development, differentiation and immune response. In this study, we identified 35 miRNAs from Marsupenaeus japonicus. Among them, fifteen miRNAs exhibited high homology to the known miRNAs(More)
The innate host defenses at mucosal surfaces are critical in the early stages of urinary tract bacterial infection. Recent studies have shown that uroepithelial cells aid innate immune cells in fighting off infection, although the exact mechanism by which the uroepithilium participates in immunity remains unclear. TLR4 has been implicated to possess(More)
Persistent halogenated organic compounds, including polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs), polybrominated diphenyl ethers (PBDEs), dechlorane plus (DP), pentabromobenzene (PBBz), and pentabromotoluene (PBT), were analyzed in pooled human serum samples from different age groups and air samples from the south coast of Laizhou Bay,(More)
Human influenza A virus (IAV) is a major cause of life-threatening respiratory tract disease worldwide. Defensins are small cationic peptides of about 2–6 kDa that are known for their broad-spectrum antimicrobial activity. Here, we focused on the anti-influenza A activity of mouse β-defensin 2 (mBD2). The prokaryotic expression plasmid pET32a-mBD2 was(More)
Influenza (flu) pandemics have posed a great threat to human health in the last century. However, current vaccination strategies and antiviral drugs provide limited protection. RNA interference (RNAi) is an effective means of suppressing influenza virus replication. PB1 is the critical protein subunit of the influenza virus RNA polymerase. The gene encoding(More)
BACKGROUND Influenza causes significant morbidity and mortality. Mammalian β-defensins are small peptides of about 4.5-6 kDa in mass and are effectors of the innate immune response with potent antimicrobial activity. In this paper, we focused on the anti-influenza A activity of the recombinant mouse β-defensin 3 (rMBD-3) in vivo and in vitro. METHODS The(More)
Experimental autoimmune encephalomyelitis (EAE) is a T-cell-mediated autoimmune demyelinating disease. The expression of chemokine receptor CXCR3 on activated T cells is crucial to direct the migration of effector cells into the inflammatory sites and initiate EAE. In this study we tested the effect of a novel recombinant immunotoxin targeting CXCR3(+)(More)
