objective: the aim of this study was to construct a pcdna3.1+ vector containing fmdv type o/irn/1/2007-vp1 gene, protein expression in bhkt7 cells and evaluation of immune response in balb/c mice. materials and methods: fmdv type o/irn/1/2007 was isolated from a cattle in ray in 2007 and serotyped. the purified vp1 gene was sub-cloned into the ptz57r/t vector and pcdna3.1+ expression vector. t...
Viral protein-1 (VP1) is a major capsid protein of Coxsakievirus B3 (CVB3) that plays an important role in directing viruses towards permissive cells and acts as a main antigenic site of the virus in eliciting of host immune response, hence it seems VP1 can be considered as a vaccine candidate against CVB3 infection. In this study, cDNA of VP1 was prepared, cloned into pET expression vector and...

Norovirus (NoV) is an etiological agent of acute gastroenteritis in humans. Genomic recombinations NoV occur mainly at the junction genes encoding RNA-dependent RNA polymerase (RdRp) and major capsid protein (viral 1, VP1), which may produce strains with novel combinations VP1- RdRp-genotypes. Here effect on changes proportions VP1-genotypes was examined through analysis observed frequencies Ja...
Foot and Mouth Disease (FMD) is highly contagious disease among cloven-hoofed animals. FMD virus has structural and non-structural proteins. Vp1 is the most immunogenic structural peptides of FMD virus, applied for major vaccine studies. Objective: Construction of Pet28-VP1 cassette for FMD virus type O/IRN/2010 and expression VP1 peptide as the most immunogenic antigen was the aim of this stud...
Enterovirus (EV71) can cause severe neurological diseases, but the underlying pathogenesis remains unclear. The capsid protein, viral protein 1 (VP1), plays a critical role in the pathogenicity of EV71. High level expression and secretion of VP1 protein are necessary for structure, function and immunogenicity in its natural conformation. In our previous studies, 5 codon-optimized VP1 DNA vaccin...
Foot-and-mouth disease virus (FMDV) serotypes O, A and Asia1 are responsible for a significant number of disease outbreaks in Iraq. The current study can be considered as the first molecular characterization of serotype Asia1 in Iraq. The present investigation reports the detection of serotype FMDV Asia1 from local farms in Sulaimani districts in 2012 and 2014 outbreaks. Phylogenetic analysis o...

We have expression-cloned in Escherichia coli the major polyoma virus capsid protein, VP1. Under the inducible control of the hybrid tac promoter, VP1 constituted between 2 and 3% of the total host cell protein. The expressed VP1 was purified to near homogeneity with initial yields to 10%. Optimal expression was temperature-dependent, and significant intracellular degradation could be demonstra...
Infectious bursal disease virus (IBDV), a member of the Birnaviridae family, is the causative agent of one of the most important infectious poultry diseases. Major aspects of the molecular biology of IBDV, such as assembly and replication, are as yet poorly understood. We have previously shown that encapsidation of the putative virus-encoded RNA-dependent RNA polymerase VP1 is mediated by its i...
