چکیده

We previously showed that modified A/Puerto Rico/8/34 (PR8) influenza master strain had improved viral rescue and growth properties in African green monkey kidney (Vero) cell line by introducing NS gene of Vero-adapted A/England/1/53 (vaEng53). In the present study, it was found that the NS1 protein derived from vaEng53 was extensively accumulated in the nuclei than that of PR8. This accumulation was caused by 7 amino acid differences in C-terminal region of NS1 protein. These results suggest that specific accumulation of NS1 protein may contribute to efficient viral replication in Vero cells.

Applying conserved peptides of NS1 Protein of avian influenza virus to differentiate infected from vaccinated chickens

Avian influenza (AI) is a highly contagious disease in poultry and outbreaks can have dramatic economic and health implications. For effective disease surveillance, rapid and sensitive assays are needed to detect antibodies against AI virus (AIV) proteins. In order to support eradication efforts of avian influenza (AI) infections in poultry, the implementation of “DIVA” vaccination strategies, ...

Cloning and Expression of Influenza H1N1 NS1 Protein in Escherichia Coli BL21

Background:Influenza virus is globally pathogenic and it is usually associated with zoonotic respiratory diseases. This virus has caused a number of pandemics with a high mortality rate. The non-structural (NS1) protein of influenza A viruses is a non-essential virulence factor that has multiple accessory functions during viral infection. This protein is highly conservative. It has been shown t...

Transfectant influenza A viruses with long deletions in the NS1 protein grow efficiently in Vero cells.

We established a reverse genetics system for the nonstructural (NS) gene segment of influenza A virus. This system is based on the use of the temperature-sensitive (ts) reassortant virus 25A-1. The 25A-1 virus contains the NS gene from influenza A/Leningrad/134/57 virus and the remaining gene segments from A/Puerto Rico (PR)/8/34 virus. This particular gene constellation was found to be respons...

Serum-free microcarrier based production of replication deficient Influenza vaccine candidate virus lacking NS1 using Vero cells

BACKGROUND Influenza virus is a major health concern that has huge impacts on the human society, and vaccination remains as one of the most effective ways to mitigate this disease. Comparing the two types of commercially available Influenza vaccine, the live attenuated virus vaccine is more cross-reactive and easier to administer than the traditional inactivated vaccines. One promising live att...

Influenza virus NS1 protein enhances the rate of translation initiation of viral mRNAs.

The effect of NS1 protein on the efficiency of influenza virus mRNA translation was evaluated by determining the accumulation of nucleoprotein (NP) or M1 mRNAs in the cytoplasm of cells expressing either of these genes alone or in combination with the NS1 gene, as well as the total cell accumulation of NP or M1 protein. Coexpression of NS1, but not of NS2 protein, led to increases in the transl...
