...re are three inactivated vaccines of H9N2 AIVs have been used in domestic poultry in China. But H9N2 AIVs occurred frequently and caused severe economic losses to the poultry industries. H9N2 AIVs can evade the pressure of vaccination by genetic evolution and antigen variation. Moreover, the ratio of L226 in the haemagglutin (HA) receptor binding site has increased, which indicates that the H9N2 virus has the increasing potential to infection and cause human e...

Recently, a significant advance in RNAi technology is the use of artificial microRNAs (amiRNAs) to fight virus infections. However, different strategies are needed to prevent virus variation or mutation escape. This review is intended to present the current situation of antiviral roles of amiRNAs, against variable RNA viruses in particu...
