| Abstract | |
The members of the family Paramyxoviridae are viruses that cause infectious in human and animals of importance to global economics. Among the member of this family include pathogens of importance global for humans such as human respiratory syncytial virus (hRSV), the human and metapneumovirus (hMPV) and of viruses importance in veterinary medicine, such as bovine respiratory syncytial virus (bRSV) and avian metapnemovírus (aMPV). The members of the Paramyxoviridae are enveloped, non-segmented viruses, with negative-sense single stranded genomes. In the first part of the study, we developed a recombinant adenovirus expressing the F protein of AMPV. The expression of F gene was determined by Western Blot. The levels of transcription were evaluated by RT-PCR in real time in HEK-293 cells and HEP-2 cells. Immunization experiment was carried out Ad-AMPV-F was analyzed and the induction of antibody response in BALB/c mice. The neutralizing antibody titers detected after immunization with Ad-AMPV-F. In the second part, the objective was to construct recombinant adenoviruses expressing the F protein of bRSV. Protein F appears to be an ideal antigen for diagnostic purposes. Using the anti-antibody AdV-5, a single band of ~ 90 kDa was detected in the culture supernatant in 293 cells infected with Ad-bRSV-F. In the third part of the study, the objective was to build two adenoviral vectors expressing the G protein of aMPV and bRSV and the expression of these proteins in infected HEK-293 cells were analyzed for expression of the reporter gene, green fluorescent protein (GFP) (AU) | |
