Infectious bursal disease virus (IBDV) is an important immunosuppressive virus of chickens. Although the gene functions of IBDV have been well characterized, the host responses during IBDV infection remain much poor. In the present study, casein kinase 1 alpha (CK1α), a novel VP2-associated protein, was down-regulated during IBDV replication in DF1 cells. Further experiments showed that siRNA-mediated...
There is an urgent need to develop new vaccines against highly pathogenic PRRS virus (HP-PRRSV) variant in China. The actual use of each codon pairs is more or less frequent than that of the statistical prediction and codon pair bias (CPB) usage affects gene translation. We “shuffled” the existing codons in HP-PRRSV genes GP5, M, nsp2 and nsp9, so that the CPB of these genes could be more negative...
The high mobility group box 1 (HMGB1) protein is an endogenous damage-associated molecular pattern (DAMP) molecule involved in the pathogenesis of various infectious agents. Based on meta-analysis of all publicly available microarray datasets, HMGB1 has recently been proposed as the most significant immune modulator during the porcine response to porcine reproductive and respiratory syndrome virus...
Two herpes simplex virus mutants containing mutated residues within the conserved Exo III motif of the polymerase gene were previously shown to be defective in 3′–5′ exonuclease activity and exhibited extremely high mutation frequencies. In this study, we have shown that these mutants also exhibited higher resistance to phosphonoacetic acid and sensitivity to aphidicolin and all nucleoside analogs...
