UNLABELLED Porcine reproductive and respiratory syndrome virus (PRRSV) nucleocapsid (N) protein is the main component of the viral capsid to encapsulate viral RNA, and it is also a multifunctional protein involved in the regulation of host cell processes. Nonstructural protein 9 (Nsp9) is the RNA-dependent RNA polymerase that plays a critical role in viral RNA transcription and replication. In ...

The first morphological evidence of African swine fever virus (ASFV) assembly is the appearance of precursor viral membranes, thought to derive from the endoplasmic reticulum, within the assembly sites. We have shown previously that protein p54, a viral structural integral membrane protein, is essential for the generation of the viral precursor membranes. In this report, we study the role of pr...

Objective(s): -methyl-D-aspartate NMDA receptor (NMDAR) and aquaporin 4 (AQP4) are involved in the molecular cascade of edema after traumatic brain injury (TBI) and are potential targets of studies in pharmacology and medicine. However, their association and interactions are still unknown.Materials and Methods: We established a rat TBI model in this study. The cellular distribution patterns of ...

conclusions our findings indicate that patients with the homozygous cc genotype in the il28b gene had a significantly higher rate of response to treatment than those with the tt or ct genotypes. nor does the il28b rs12979860 polymorphism affect the viral load. results the genotype frequencies of rs12979860 polymorphism in group 1 were cc (28.9%), ct (37.8%) and tt (33.3%) and in group 2 were cc...

Two poliovirus mutants were isolated that contain an oligonucleotide linker insertion in the 2C-coding region of the viral genome. One, 2C-31, has a strongly temperature-sensitive phenotype and the other, 2C-32, forms small plaques on HeLa cell monolayers at all temperatures. Both mutants have a severe temperature-sensitive defect in viral RNA synthesis but little effect on the types of viral p...

Parainfluenza virus 5 (PIV5) is a prototypical paramyxovirus. The V/P gene of PIV5 encodes two mRNA species through a process of pseudotemplated insertion of two G residues at a specific site during transcription, resulting in two viral proteins, V and P, whose N termini of 164 amino acid residues are identical. Previously it was reported that mutating six amino acid residues within this identi...

results based on our results, mab against recombinant erns was produced and reacted successfully with recombinant and natural antigens. conclusions with regards to the role of erns in the identification of pi animals, it appears that erns recombinant antigen and the specific monoclonal antibodies produced against it may be suitable for developing bvdv laboratory diagnostic assays. objectives er...

Enterovirus 71 (EV-A71) causes hand, foot and mouth disease in young children and infants, but can also cause severe neurological complications or even death. The double-stranded RNA (dsRNA)-dependent protein kinase R (PKR), an interferon-induced antiviral protein, phosphorylates the regulatory α-subunit of the eukaryotic translation initiation factor 2 in response to viral infection, thereby b...
