Abstract
Influenza viruses cause annual seasonal epidemics and occasional pandemics of human respiratory disease. Influenza virus infections represent a serious public health and economic problem, which are most effectively prevented through vaccination. However, influenza viruses undergo continual antigenic variation, which requires either the annual reformulation of seasonal influenza vaccines or the rapid generation of vaccines against potential pandemic virus strains. The segmented nature of influenza virus allows for the reassortment between two or more viruses within a co-infected cell, and this characteristic has also been harnessed in the laboratory to generate reassortant viruses for their use as either inactivated or live-attenuated influenza vaccines. With the implementation of plasmid-based reverse genetics techniques, it is now possible to engineer recombinant influenza viruses entirely from full-length complementary DNA copies of the viral genome by transfection of susceptible cells. These reverse genetics systems have provided investigators with novel and powerful approaches to answer important questions about the biology of influenza viruses, including the function of viral proteins, their interaction with cellular host factors and the mechanisms of influenza virus transmission and pathogenesis. In addition, reverse genetics techniques have allowed the generation of recombinant influenza viruses, providing a powerful technology to develop both inactivated and live-attenuated influenza vaccines. In this review, we will summarize the current knowledge of state-of-the-art, plasmid-based, influenza reverse genetics approaches and their implementation to provide rapid, convenient, safe and more effective influenza inactivated or live-attenuated vaccines.

Influenza virus infections represent a serious public health and economic problem, which are most effectively prevented through vaccination. However, influenza viruses undergo continual antigenic variation, which requires either the annual reformulation of seasonal influenza vaccines or the rapid generation of vaccines against potential pandemic virus strains. The segmented nature of influenza virus allows for the reassortment between two or more viruses within a co-infected cell, and this characteristic has also been harnessed in the laboratory to generate reassortant viruses for their use as either inactivated or live-attenuated influenza vaccines. With the implementation of plasmid-based reverse genetics techniques, it is now possible to engineer recombinant influenza viruses entirely from full-length complementary DNA copies of the viral genome by transfection of susceptible cells. These reverse genetics systems have provided investigators with novel and powerful approaches to answer important questions about the biology of influenza viruses, including the function of viral proteins, their interaction with cellular host factors and the mechanisms of influenza virus transmission and pathogenesis. In addition, reverse genetics techniques have allowed the generation of recombinant influenza viruses, providing a powerful technology to develop both inactivated and live-attenuated influenza vaccines. In this review, we will summarize the current knowledge of state-of-the-art, plasmid-based, influenza reverse genetics approaches and their implementation to provide rapid, convenient, safe and more effective influenza inactivated or live-attenuated vaccines.</p></abstract><kwd-group><kwd>influenza vaccines</kwd><kwd>influenza virus</kwd><kwd>reverse genetics</kwd><kwd>live-attenuated influenza virus</kwd><kwd>influenza inactivated virus</kwd><kwd>recombinant influenza virus</kwd><kwd>vaccination</kwd><kwd>antivirals</kwd><kwd>universal vaccines</kwd></kwd-group></article-meta></front><floats-group><fig id="ijms-18-00020-f001" position="float"><label>Figure 1</label><caption><p>Virion structure of IAV (<bold>A</bold>) and IBV (<bold>B</bold>): IAV and IBV are surrounded by a lipid bilayer containing the two viral glycoproteins hemagglutinin (HA), responsible for binding to sialic acid-containing receptors in the surface of susceptible cells, and neuraminidase (NA), responsible for viral release from infected cells. Furthermore, in the virion membrane is the ion channel M2 (IAV) or BM2 and NB (IBV) proteins. Under the viral lipid bilayer is a protein layer composed of the M1 protein, which plays a role in virion assembly and budding, and the nuclear export protein (NEP) involved in the nuclear export of the viral ribonucleoprotein (vRNP) complexes. The eight viral segments and protein products are indicated inside the virions. Black lines at the end of each of the eight IAV and IBV vRNAs indicate the 3′ and 5′ non-coding regions (NCR).

Transcription from the Pol-I cassette results in vRNAs identical to those present in influenza virus, allowing their recognition by the influenza polymerase complex.

After translation, influenza NP and polymerase complex PA, PB1 and PB2 associate with the vRNAs to form the viral ribonucleoprotein (vRNP) complexes and initiate transcription from the viral promoter located within the non-coding regions at the 3′ termini of the vRNAs. Transcription results in the synthesis of more mRNAs and proteins. The influenza polymerase complex also replicates the vRNAs into complementary (c)RNAs that serve as templates for the amplification of vRNAs. Newly-synthesized vRNAs, together with the structural viral proteins result in the formation of new influenza viruses.
