protein sequences for predicting antigenicity of diverse influenza A viruses. Background: The evolution of influenza A viruses leads to the antigenic changes. Serological diagnosis of the antigenicity is usually labor-intensive, time-consuming and not suitable for early-stage detection.

Our results revealed a striking diversity of A-to-I RNA editing activities in human epithelial cells in responses to different subtypes of influenza A viruses. Next, the expression levels of ADAR and APOBEC enzymes responsible for A-to-I and C-to-U RNA editing during the course of virus infection were examined. The increase of A-to-I RNA editing activities in infections with some influenza A viruses (H1N1 and H3N2) is linked to the up-regulation of ADAR1 but not ADAR2.

Computational analysis of the receptor binding specificity of novel influenza A/H7N9 viruses. Conclusion: The results are novel and specific to the emerging influenza A/Taiwan/1/2017(H7N9) strain compared with A/Shanghai/02/2013(H7N9). Influenza A viruses are undergoing continuous and rapid evolution, leading to the concerns about an outbreak or even a pandemic [1].

Influenza A viruses are enveloped viruses classified in the Orthomyxoviridae family. New virus subtypes are emerging as a result of genome mutations causing changes in the amino acid composition of viral proteins, primarily the virus’s surface antigen proteins, hemagglutinin (HA) and neuraminidase (NA)..

In addition, animals with transgene for prion protein to a tandem repeat deleted model were also highly susceptible to influenza A virus infection. The results indicate that prion protein is also important in the susceptibility of influenza A viruses [42]. A previous study reported that chicken prion mRNA was overexpressed in Marek’s disease-infected chicken embryo fibroblasts and that knockdown of chicken prion protein in Marek’s disease virus-infected avian T cells reduced cell viability.
