        Abstract
        The highly pathogenic avian influenza (HPAI) H5N1 viruses, especially the
        laboratory-generated H5N1 mutants, have demonstrated the potential to
        cross the species barrier and infect mammals and humans. Consequently,
        the design of an effective and safe anti-H5N1 vaccine is essential.
        We previously demonstrated that the full-length hemagglutinin 1 (HA1)
        could induce significant neutralizing antibody response and protection.
        Here, we intended to identify the critical neutralizing domain (CND) in
        an optimal conformation that can elicit strong cross-neutralizing antibodies
        and protection against divergent H5N1 strains. We thus constructed six
        recombinant proteins covering different regions of HA1 of A/Anhui/1/2005(H5N1),
        each of which was fused with foldon (Fd) and Fc of human IgG. We found that
        the critical fragment fused with Fd/Fc (HA-13-263-Fdc, H5 numbering) that
        could elicit the strongest neutralizing antibody response is located in the
        N-terminal region of HA1 (residues 13-263), which covers the receptor-binding
        domain (RBD, residues 112-263). We then constructed three additional
        recombinants fused with Fd plus His tag (HA-13-263-Fd-His), Fc only
        (HA-13-263-Fc), and His tag only (HA-13-263-His), respectively.
        We found that the HA-13-263-Fdc, which formed an oligomeric
        conformation, induced the strongest neutralizing antibody response
        and cross-protection against challenges of two tested H5N1 virus
        strains covering clade 1: A/VietNam/1194/2004 (VN/1194) or
        clade 2.3.4: A/Shenzhen/406H/06 (SZ/406H), while HA-13-263-Fc
        dimer and HA-13-263-Fd-His trimer elicited higher neutralizing antibody
        response and protection than HA-13-263-His monomer. These results
        suggest that the oligomeric form of the CND containing the RBD can
        be further developed as an effective and safe vaccine for cross-protection
        against divergent strains of H5N1 viruses.

          Rhinovirus and influenza
          ================================================== ====
          HRVs were proportionately under-represented among viral co-detections. For some period, HRVs may render the host less likely to be infected by other viruses.

          For some period, human rhinovirus may render the host less likely to be infected by other viruses.
          In contrast to the experience in other European countries, the onset of the A(H1N1)2009 influenza virus epidemic was unexpectedly slow in France during the first part of autumn 2009. Our objective was to test the hypothesis that intense circulation of rhinoviruses might have reduced the probability …

          Rhinoviruses delayed the circulation of the pandemic influenza A (H1N1) 2009 virus in France.
          Viral co-infections were relatively common in H1N1 infected hospitalized children and need to be considered when estimating morbidity attributed to H1N1. Population-based longitudinal studies with repeated sampling are needed to improve the understanding of the importance of co-infections and viral …

          H1N1 was found in 83 (16.5%) children and of these 12 (14.5%) were co-infections
          6.0% of the H1N1-positive children were also positive for HRV.
          To determine the role of the pandemic influenza A/H1N1 2009 (A/H1N1 2009pdm) in acute respiratory tract infections (ARTIs) and its impact on the epidemic of seasonal influenza viruses and other common respiratory viruses, nasal and throat swabs taken from 7,776 patients with suspected viral ARTIs fr …

          We observed a distinctive dual peak pattern of influenza epidemic during the A/H1N1 2009pdm
          in Beijing, China, which was formed by the A/H1N1 2009pdm, and a subsequent influenza B
          epidemic in year 2009/2010.
          Parallel detection of multiple respiratory viruses shows that the epidemic of common
          respiratory viruses, except human rhinovirus, was delayed during the pandemic of the
          A/H1N1 2009pdm
          Our results suggest that NIRV co-infections during Influenza epidemics may act as cofactors that contribute to shape an outbreak and modulate the attack rate. They further warrant broad spectrum studies to fully understand viral epidemics.

          RESULTS: Two successive waves of viral infections were identified: a first wave (W33-37)
          when pH1N1 was dominant and co-circulated with NIRVs(non-influenza-respiratory-viruses),
          sharply interrupted by a second wave (W38-44), almost exclusively composed of NIRVs,
          mainly human Rhinoviruses (hRV) and Coronaviruses (hCoV). Data suggest that some
          interference may occur between NIRVs and pH1N1 when they co-circulate within the
          same household, where NIRVs were more likely to infect pH1N1 negative individuals
          than pH1N1 positive peers (relative risk: 3.13, 95% CI: 1.80-5.46, P<0.001).
          Viral shedding was significantly shorter (P = 0.035) in patients who were co-infected
          by pH1N1 and NIRV or by two different NIRVs compared to those who were infected
          with only one virus, whatever this virus was (pH1N1 or NIRVs). Although intense
          co-circulation of NIRVs (especially hRV) likely brought pH1N1 under the detection
          threshold, it did not prevent spread of the pandemic Influenza virus within the susceptible
          population nor induction of an extensive herd immunity to it.

            Highly pathogenic avian influenza viruses (HPAIV) originate from avirulent precursors but differ from all other influenza viruses by the presence of a polybasic cleavage site in their hemagglutinins (HA) of subtype H5 or H7.

            A Vero cell derived whole virus non-adjuvanted H5N1 influenza vaccine is well tolerated and induces long-lasting cross-clade immunological memory that can be effectively boosted 1-2 years after two dose or single dose priming, supporting its suitability for pre-pandemic vaccination.

            CONCLUSIONS: A Vero cell derived whole virus non-adjuvanted H5N1 influenza vaccine

            Influenza viruses are adept in human populations.

            5. Conclusions
            Live-attenuated influenza vaccine could provide protection against influenza viruses
            of different subtypes. Multiple types of H5N1 live-attenuated vaccines could be
            developed based on existing vaccine production technologies and capacities.
            In addition, the research and development of adjuvants for live-attenuated vaccines
            is worthy of attention and effort, as safe and effective adjuvants can effectively
            lower the dose of vaccines and expand suitable ranges of vaccination.


            adenovirus vectored
            There is no doubt that significant progress has been made, during the past decade,
            in the field of the rAd-vectored H5N1 influenza vaccines. However, these vaccines
            must overcome several challenges before they can be considered a suitable alternative
            to the currently licensed vaccines.
            Mounting evidence indicates that mucosal and T cell mediated immunity may actually
            more important than previously realized against a broad spectrum of H5N1 strains
            [118,119,121,123,128,129].
            The cross-protection achieved by vaccination with rAd vaccines encoding HA and/or
            conserved antigens is very encouraging [52,87,129,147].
            VLP based vaccines can induce both humoral and cellular immunity in nonclinical studies
            and have looked very promising in clinical trials [178]
            we believe that the rAd vectored nasal influenza vaccines hold great promise for the
            influenza pandemic preparedness




            Pre-pandemic "avian" H5N1 and pandemic 2009 (H1N1) vaccines can achieve
            satisfactory immunogenicity
            the best available option in a pandemic is currently represented by oil-in-water adjuvanted
            vaccines, administered in two doses containing each 3.8–6 μg of hemagglutinin antigen.
            These formulations were more prone to cause adverse reactions, but they were the only
            preparations showing acceptable immunogenicity rates (≥ 70%), so the trade-off may be
            considered acceptable.6
            Finally, both reviews found no serious vaccine-related adverse events, and concluded
            that all tested vaccines had an acceptable safety profile. In the absence of studies on
            clinical outcomes, however, the efficacy/effectiveness of the vaccine cannot be taken
            for granted.

            Highly pathogenic avian influenza H5N1 is a threat to global public health as a natural pandemic causing agent but has recently been considered a bioterrorism concern. The evolving view of the H5N1 virus necessitates the re-evaluation of the current status of H5N1 therapeutics and prophylactics, in …

            In summary, an efficacious H5N1 vaccine is urgently needed and the ferret model
            remains an appropriate model for its development.

              NS-reassortment of H5N1 HPAIV viruses in the background of A/FPV/Rostock/1934
              (H7N1) HPAIV has been shown to change virus replication kinetics and host cell response
              in mammalian cells the NS-segment of A/Vietnam/1203/2004 (FPV NS VN, H5N1) HPAIV
              significantly altered the characteristics of the H7-prototype HPAIV in tracheal organ
              cultures (TOC) of chicken and turkey in vitro, with decreased replication efficiency
              accompanied by increased induction of type I interferon (IFN) and apoptosis.
              NS-reassortant FPV NS VN showed an overall highly-pathogenic phenotype with increased

              of chicken and turkey embryos.
              Highly pathogenic avian influenza viruses (HPAIV) of subtypes H5 and H7 have caused numerous outbreaks in diverse poultry species and rising numbers of human infections.

              To better understand host adaptation between mammalian species in real time, we passaged
              mouse-adapted A/PR8/34 (PR8) in guinea pigs. Guinea pigs, unlike mice, support spontaneous
              and robust IAV transmission. For some IAV strains, including PR8, adaptation is required for a
              virus to attain transmissibility,

              Multiple guinea pig-adapted PR8 mutants generated by serial nasal wash passaging in independent
              lines replicated more efficiently and transmitted by co-caging. All transmissible variants possessed
              one of two non-synonymous mutations in M1, either alone or in combination with mutations in
              PB2, HA, NP or NA. Rapid reassortment between independently selected variants combined beneficial
              mutations in NP and M1 to form the fittest transmitting virus. These findings provide further insight
              into genetic determinants in NP and M1 involved in PR8 IAV adaptation to transmit in a new host,
              and clearly show the benefit of a segmented genome in rapidly generating optimal combinations of
              mutations in IAV evolution

              the H1N1pdm strain. Our studies suggest that ferrets recapitulate influenza virus reassortment events.

                A United States interagency avian influenza surveillance plan was initiated in 2006 for early detection of highly pathogenic avian influenza viruses (HPAIV) in wild birds. The plan included a variety of wild bird sampling strategies including the testing of fecal samples from aquatic areas throughout the United States from April 2006 through December 2007. Although HPAIV was not detected through this surveillance effort we were able to obtain 759 fecal samples that were positive for low pathogenic avian influenza virus (LPAIV). We used 136 DNA sequences obtained from these samples along with samples from a public influenza sequence database for a phylogenetic assessment of hemagglutinin (HA) diversity in the United States. We analyzed sequences from all HA subtypes except H5, H7, H14 and H15 to examine genetic variation, exchange between Eurasia and North America, and geographic distribution of LPAIV in wild birds in the United States. This study confirms intercontinental exchange of some HA subtypes (including a newly documented H9 exchange event), as well as identifies subtypes that do not regularly experience intercontinental gene flow but have been circulating and evolving in North America for at least the past 20 years. These HA subtypes have high levels of genetic diversity with many lineages co-circulating within the wild birds of North America. The surveillance effort that provided these samples demonstrates that such efforts, albeit labor-intensive, provide important information about the ecology of LPAIV circulating in North America.

                Approximately 1000 wild bird fecal samples per U.S. state were
                collected in 2006 for a total of 50184 samples. In 2007, a sampling
                scheme based on a weighted allocation of key flyway states and
                regions that had high recovery in 2006 was used and 25348
                additional samples were obtained

                  Background The ISA virus (ISAV) is an Orthomyxovirus whose genome encodes for at least 10 proteins. Low protein identity and lack of genetic tools have hampered the study of the molecular mechanism behind its virulence. It has been shown that viral codon usage controls several processes such as translational efficiency, folding, tuning of protein expression, antigenicity and virulence. Despite this, the possible role that adaptation to host codon usage plays in virulence and viral evolution has not been studied in ISAV. Methods Intergenomic adaptation between viral and host genomes was calculated using the codon adaptation index score with EMBOSS software and the Kazusa database. Classification of host genes according to GeneOnthology was performed using Blast2go. A non parametric test was applied to determine the presence of significant correlations among CAI, mortality and time. Results Using the codon adaptation index (CAI) score, we found that the encoding genes for nucleoprotein, matrix protein M1 and antagonist of Interferon I signaling (NS1) are the ISAV genes that are more adapted to host codon usage, in agreement with their requirement for production of viral particles and inactivation of antiviral responses. Comparison to host genes showed that ISAV shares CAI values with less than 0.45% of Salmo salar genes. GeneOntology classification of host genes showed that ISAV genes share CAI values with genes from less than 3% of the host biological process, far from the 14% shown by Influenza A viruses and closer to the 5% shown by Influenza B and C. As well, we identified a positive correlation (p

                        Upon co-infection with influenza B virus (FluB), influenza A virus (FluA) replication is substantially impaired. Previously, we have shown that the nucleoprotein of FluB (BNP) can inhibit FluA polymerase machinery, retarding the growth of FluA. However, the molecular mechanism underlying this inhibi …

                        novel role of flu-B segment 5 as an anti-influenza A viral agent
                        The epidemiological and evolutionary dynamics of the two cocirculating lineages of influenza B virus, Victoria and Yamagata, are poorly understood, especially in tropical or subtropical areas of Southeast Asia. We performed a phylogenetic analysis of the hemagglutinin (HA) and neuraminidase (NA) seq …

                        reassortment events among the Victoria and Yamagata lineages
                        Significant variation was found among influenza B strains isolated in Zhejiang province from 1999 to 2012. The surface HAl gene evolved more rapidly than internal genes. Gene reassortment and gene mutation were the main evolutionary mechanism of influenza B virus.

                        Nucleotide substitution rates of HAl , NP, M and NS genes were estimated to be
                        2. 29 x 10 -3 ,1. 39 X 10-3 ,1. 78 X 10-3 ,1. 30 X 10-3 /site per year, respectively.
                        Variations of amino acid of HAl domain of Victoria-like isolates mainly included
                        K48E ,L58P ,N75K,K80R,K129N/S,N165K,S172P ,Sl97N/D and A202V;
                        while those in Yamagata-like isolates were R48K, S1501, N166Y, N203S, G230D and D233N.
                        Determined amino acid sequences of NP of Victoria-like influenza B isolates were
                        similar to Yamagata-like isolates after 2010 and variations happened on four characteristic
                        amino acid sites, naming A60D, I233V, N513S and V5341, compared with previous
                        Victoria-like influenza B isolates.

                            bradykinin 2 receptor (BKB2R) was identified as a principal host protein which could
                            mediate molecular processes underlying the cardioprotective effect of influenza vaccines
                            we suggest that some antibodies elicited by influenza vaccines act as agonists,
                            which activate a BKB2R-associated signaling pathway contributing to the protection against CVD.
                            [I'd always thought that influenza infection itself triggers CVD and CVD-deaths, as is seen in the
                            weekly charts.And thus vaccination, prevention of influenza reduces CVD-deaths]

                              anti-IAV potential of a proanthocyanidin-enriched extract derived from the aerial parts of Rumex acetosa
                              Infections by influenza A viruses (IAV) are a major health burden to mankind. The current antiviral arsenal against IAV is limited and novel drugs are urgently required. Medicinal plants are known as an abundant source for bioactive compounds, including antiviral agents. The aim of the present study was to characterize the anti-IAV potential of a proanthocyanidin-enriched extract derived from the aerial parts of Rumex acetosa (RA), and to identify active compounds of RA, their mode of action, and structural features conferring anti-IAV activity. In a modified MTT (MTTIAV) assay, RA was shown to inhibit growth of the IAV strain PR8 (H1N1) and a clinical isolate of IAV(H1N1)pdm09 with a half-maximal inhibitory concentration (IC50) of 2.5 µg/mL and 2.2 µg/mL, and a selectivity index (SI) (half-maximal cytotoxic concentration (CC50)/IC50)) of 32 and 36, respectively. At RA concentrations>1 µg/mL plaque formation of IAV(H1N1)pdm09 was abrogated. RA was also active against an oseltamivir-resistant isolate of IAV(H1N1)pdm09. TNF-α and EGF-induced signal transduction in A549 cells was not affected by RA. The dimeric proanthocyanidin epicatechin-3-O-gallate-(4β→8)-epicatechin-3′-O-gallate (procyanidin B2-di-gallate) was identified as the main active principle of RA (IC50 approx. 15 µM, SI≥13). RA and procyanidin B2-di-gallate blocked attachment of IAV and interfered with viral penetration at higher concentrations. Galloylation of the procyanidin core structure was shown to be a prerequisite for anti-IAV activity; o-trihydroxylation in the B-ring increased the anti-IAV activity. In silico docking studies indicated that procyanidin B2-di-gallate is able to interact with the receptor binding site of IAV(H1N1)pdm09 hemagglutinin (HA). In conclusion, the proanthocyanidin-enriched extract RA and its main active constituent procyanidin B2-di-gallate protect cells from IAV infection by inhibiting viral entry into the host cell. RA and procyanidin B2-di-gallate appear to be a promising expansion of the currently available anti-influenza agents.
