Abstract
Influenza viruses are known to cause severe respiratory infections in humans, often associated with significant morbidity and mortality rates. Virus replication relies on various host factors and pathways, which also determine the virus's infectious potential. Nonetheless, achieving a comprehensive understanding of how the virus interacts with host cellular components is essential for developing effective therapeutic strategies. One of the key components among host factors, the nuclear pore complex (NPC), profoundly affects both the Influenza virus life cycle and the host's antiviral defenses. Serving as the sole gateway connecting the cytoplasm and nucleoplasm, the NPC plays a vital role as a mediator in nucleocytoplasmic trafficking. Upon infection, the virus hijacks and alters the nuclear pore complex and the nuclear receptors. This enables the virus to infiltrate the nucleus and promotes the movement of viral components between the nucleus and cytoplasm. While the nucleus and cytoplasm play pivotal roles in cellular functions, the nuclear pore complex serves as a crucial component in the host's innate immune system, acting as a defense mechanism against virus infection. This review provides a comprehensive overview of the intricate relationship between the Influenza virus and the nuclear pore complex. Furthermore, we emphasize their mutual influence on viral replication and the host's immune responses.

Qin L, Rao T, Li X, Chen H, Qian P. DnaJA2 interacts with Japanese encephalitis virus NS3 via its C-terminal to promote viral infection. Virus Res 2023; 336:199210. [PMID: 37633595 PMCID: PMC10485146 DOI: 10.1016/j.virusres.2023.199210] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 08/23/2023] [Accepted: 08/24/2023] [Indexed: 08/28/2023]
Abstract
Numerous studies have documented that the interaction of viral and cellular proteins is essential in the viral life cycle. In our previous study, to screen cellular proteins that take part in the life cycle of JEV, cellular proteins that interacted with JEV NS3 were identified by Co-immunoprecipitation coupled with mass spectrometry analysis (Co-IP-MS), the results showed that ILF2, DnaJA1, DnaJA2, CKB, TUFM, and PABPC1 that putatively interact with NS3. Another candidate protein, DnaJA2, which interacted with JEV NS3 protein, was selected for further study. Overexpression of DnaJA2 increased JEV infection. Conversely, the knockdown of DnaJA2 suppressed JEV infection. Furthermore, DnaJA2 interacted with NS5 besides NS3 and colocalized with viral dsRNA. Additionally, the level of viral NS3 protein expression was higher in cells overexpressing DnaJA2 than in cells with empty vector expression, whereas DnaJA2 knockdown resulted in NS3 protein degradation, which was subsequently restored by MG132 treatment. Further analysis revealed that the C-terminal of DnaJA2 was a critical domain for interaction with NS3 and promoted JEV infection. Collectively, our study identified DnaJA2 as an essential host factor required for JEV infection, potentially representing a novel therapeutic target for the development of antiviral therapies against JEV.

Abstract
Lysine methylation is a post-translational modification of histone and non-histone proteins and affects numerous cellular processes. The actin histidine methyltransferase SET domain containing 3 (SETD3) is a member of the protein lysine methyltransferase (PKMT) family which catalyse the addition of methyl groups to lysine residues. However, the role of SETD3 in virus-mediated innate immune responses has rarely been investigated. In this study, zebrafish SETD3 was shown to be induced by poly(I:C) and spring viremia of carp virus (SVCV) and inhibited virus infection. Further, it was found that SETD3 directly interacted with SVCV phosphoprotein (SVCV P) in the cytoplasm of EPC cells, initiating ubiquitination to degrade the SVCV P protein via the proteasomal pathway. Interestingly, mutants lacking the SET and RSB domains were able to promote degradation of SVCV P, indicating that they are not required for SETD3 mediated degradation of SVCV P. Taken together, our study demonstrates that SETD3 is an antiviral factor which limits virus replication by promoting ubiquitination of viral phosphoprotein and subsequent protein degradation.

Abstract
There exist several databases that provide virus-host protein interactions. While most provide curated records of interacting virus-host protein pairs, information on the strain-specific virulence factors or protein domains involved, is lacking. Some databases offer incomplete coverage of influenza strains because of the need to sift through vast amounts of literature (including those of major viruses including HIV and Dengue, besides others). None have offered complete, strain specific protein-protein interaction records for the influenza A group of viruses. In this paper, we present a comprehensive network of predicted domain-domain interaction(s) (DDI) between influenza A virus (IAV) and mouse host proteins, that will allow the systematic study of disease factors by taking the virulence information (lethal dose) into account. From a previously published dataset of lethal dose studies of IAV infection in mice, we constructed an interacting domain network of mouse and viral protein domains as nodes with weighted edges. The edges were scored with the Domain Interaction Statistical Potential (DISPOT) to indicate putative DDI. The virulence network can be easily navigated via a web browser, with the associated virulence information (LD50 values) prominently displayed. The network will aid influenza A disease modeling by providing strain-specific virulence levels with interacting protein domains. It can possibly contribute to computational methods for uncovering influenza infection mechanisms mediated through protein domain interactions between viral and host proteins.

Abstract
Influenza A viruses still represent a major health issue, for both humans and animals. One of the main viral proteins of interest to target is the NS1 protein, which counters the host immune response and promotes viral replication. NS1 is a homodimer composed of a dimeric RNA-binding domain (RBD), which is structurally stable and conserved in sequence, and two effector domains that are tethered to the RBD by linker regions. This linker flexibility leads to NS1 polymorphism and can therefore exhibit different forms. Previously, we identified a putative drug-binding site, located in the RBD interface in a crystal structure of NS1. This pocket could be targeted to block RNA binding and inhibit NS1 activities. The objective of the present study is to confirm the presence of this druggable site, whatever the sequence variants, in order to develop a universal therapeutic compound that is insensitive to sequence variations and structural flexibility. Using a set of four NS1 full-length structures, we combined different bioinformatics approaches such as pocket tracking along molecular dynamics simulations, druggability prediction and classification. This protocol successfully confirmed a frequent large binding-site that is highly druggable and shared by different NS1 forms, which is promising for developing a robust NS1-targeted therapy.

Phosphatidylinositol 4,5-Bisphosphate Mediates the Co-Distribution of Influenza A Hemagglutinin and Matrix Protein M1 at the Plasma Membrane. Viruses 2022; 14:v14112509. [PMID: 36423118 PMCID: PMC9698905 DOI: 10.3390/v14112509] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Revised: 11/04/2022] [Accepted: 11/08/2022] [Indexed: 11/16/2022] Open
Abstract
The fully assembled influenza A virus (IAV) has on its surface the highest density of a single membrane protein found in nature-the glycoprotein hemagglutinin (HA) that mediates viral binding, entry, and assembly. HA clusters at the plasma membrane of infected cells, and the HA density (number of molecules per unit area) of these clusters correlates with the infectivity of the virus. Dense HA clusters are considered to mark the assembly site and ultimately lead to the budding of infectious IAV. The mechanism of spontaneous HA clustering, which occurs with or without other viral components, has not been elucidated. Using super-resolution fluorescence photoactivation localization microscopy (FPALM), we have previously shown that these HA clusters are interdependent on phosphatidylinositol 4,5-biphosphate (PIP2). Here, we show that the IAV matrix protein M1 co-clusters with PIP2, visualized using the pleckstrin homology domain. We find that cetylpyridinium chloride (CPC), which is a positively charged quaternary ammonium compound known for its antibacterial and antiviral properties at millimolar concentrations, disrupts M1 clustering and M1-PIP2 co-clustering at micromolar concentrations well below the critical micelle concentration (CMC). CPC also disrupts the co-clustering of M1 with HA at the plasma membrane, suggesting the role of host cell PIP2 clusters as scaffolds for gathering and concentrating M1 and HA to achieve their unusually high cluster densities in the IAV envelope.

Abstract
Influenza A viruses (IAVs) rely on viral ribonucleoprotein (vRNP) complexes to control transcription and replication. Each vRNP consists of one viral genomic RNA segment associated with multiple nucleoproteins (NP) and a trimeric IAV RNA polymerase complex. Previous studies showed that post-translational modifications of vRNP components, such as NP, by host factors would in turn affect the IAV life cycle or modulate host anti-viral response. In this study, we found host E3 ubiquitin ligase Pirh2 interacted with NP and mediated short-chain ubiquitination of NP at lysine 351, which suppressed NP-PB2 interaction and vRNP formation. In addition, we showed that knockdown of Pirh2 promoted IAV replication, whereas overexpression of Pirh2 inhibited IAV replication. However, Pirh2-ΔRING lacking E3 ligase activity failed to inhibit IAV infection. Moreover, we showed that Pirh2 had no effect on the replication of a rescued virus, WSN-K351R, carrying lysine-to-arginine substitution at residue 351. Interestingly, by analyzing human and avian IAVs from 2011 to 2020 in influenza research databases, we found that 99.18% of 26 977 human IAVs encode lysine, but 95.3% of 9956 avian IAVs encode arginine at residue 351 of NP protein. Consistently, knockdown of Pirh2 failed to promote propagation of two avian-like influenza viruses, H9N2-W1 and H9N2-C1, which naturally encode arginine at residue 351 of NP. Taken together, we demonstrated that Pirh2 is a host factor restricting IAV infection by modulating short-chain ubiquitination of NP. Meanwhile, it is noteworthy that residue 351 of NP targeted by Pirh2 may associate with the evasion of human anti-viral response against avian-like influenza viruses.

Abstract
BACKGROUND Porcine reproductive and respiratory syndrome virus 2 (PRRSV-2) is a constant threat to the swine industry worldwide. 2', 5'-oligoadenylate synthetase-like (OASL) protein has antiviral activity, but this has not been demonstrated for PRRSV-2, and the mechanism is not well elucidated. RESULTS In this study, the expression of OASL1 in porcine alveolar macrophages (PAMs) induced by interferon (IFN)-β stimulation and PRRSV-2 infection was examined by quantitative real-time polymerase chain reaction and western blotting. Ectopic expression and knockdown of porcine OASL1 (pOASL1) indicated the role of OASL1 in PRRSV-2 replication cycle. Results showed that the expression of OASL1 in PAMs was significantly increased by IFN-β stimulation or PRRSV-2 infection. OASL1 specific small interfering RNA promoted PRRSV-2 replication, whereas ectopic expression of pOASL1 inhibited PRRSV-2 infection. The mechanism revealed OASL1 interacts with Melanoma differentiation-associated protein 5 (MDA5) to increase IFN responses, and the anti-PRRSV-2 activity was lost after the knockdown of the MDA5 RNA sensor. CONCLUSIONS OASL1 inhibits PRRSV-2 infection via the activation of MDA5.

Abstract
Influenza viruses, respiratory syncytial virus (RSV), and SARS-COV2 are among the most dangerous respiratory viruses. Zinc is one of the essential micronutrients and is very important in the immune system. The aim of this narrative review is to review the most interesting findings about the importance of zinc in the anti-viral immune response in the respiratory tract and defense against influenza, RSV, and SARS-COV2 infections. The most interesting findings on the role of zinc in regulating immunity in the respiratory tract and the relationship between zinc and acute respiratory distress syndrome (ARDS) are reviewed, as well. Besides, current findings regarding the relationship between zinc and the effectiveness of respiratory viruses' vaccines are reviewed. The results of reviewed studies have shown that zinc and some zinc-dependent proteins are involved in anti-viral defense and immune regulation in the respiratory tract. It seems that zinc can reduce the viral titer following influenza infection. Zinc may reduce RSV burden in the lungs. Zinc can be effective in reducing the duration of viral pneumonia symptoms. Zinc may enhance the effectiveness of hydroxychloroquine in reducing mortality rate in COVID-19 patients. Besides, zinc has a positive effect in preventing ARDS and ventilator-induced lung damage. The relationship between zinc levels and the effectiveness of respiratory viruses' vaccines, especially influenza vaccines, is still unclear, and the findings are somewhat contradictory. In conclusion, zinc has anti-viral properties and is important in defending against respiratory viral infections and regulating the immune response in the respiratory tract.

Abstract
Isarubrolone C is a bioactive polycyclic tropoloalkaloid from Streptomyces. Our previous study showed that isarubrolone C could trigger autophagy. Here, we report isarubrolone C potential in broad-spectrum antiviral effect and its antiviral mechanism in vitro. Our results show that isarubrolone C activated autophagy and reduced levels of viral proteins in the cells harboring HCV-CORE/NS5B, HBx, ZIKV-NS5, and HIV-RT, respectively. The role of isarubrolone C in suppression of the viral proteins was via an autophagic degradation pathway rather than a proteasome pathway. Co-immunoprecipitation assays revealed that isarubrolone C promoted both autophagy flux opening and the viral proteins being enwrapped in autolysosomes. PCR assays showed that isarubrolone C elevated the transcription levels of ATG10/ATG10S and IL28A. Further, ATG10S high expression could efficiently enhance IL28A expression and the ability of isarubrolone C to degrade the viral proteins by promoting the colocalization of viral proteins with autolysosomes. Additionally, knockdown of endogenous IL28A caused both losses of the isarubrolone C antiviral effect and autolysosome formation. These results indicate that the role of isarubrolone C antiviruses is achieved by triggering the autophagic mechanism, which is mediated by endogenous ATG10S and IL28A activation. This is the first report about isarubrolone C potential of in vitro broad-spectrum antiviruses.

p21 restricts influenza A virus by perturbing the viral polymerase complex and upregulating type I interferon signaling. PLoS Pathog 2022; 18:e1010295. [PMID: 35180274 PMCID: PMC8920271 DOI: 10.1371/journal.ppat.1010295] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Revised: 03/14/2022] [Accepted: 01/20/2022] [Indexed: 11/19/2022] Open
Abstract
Many cellular genes and networks induced in human lung epithelial cells infected with the influenza virus remain uncharacterized. Here, we find that p21 levels are elevated in response to influenza A virus (IAV) infection, which is independent of p53. Silencing, pharmacological inhibition or deletion of p21 promotes virus replication in vitro and in vivo, indicating that p21 is an influenza restriction factor. Mechanistically, p21 binds to the C-terminus of IAV polymerase subunit PA and competes with PB1 to limit IAV polymerase activity. Besides, p21 promotes IRF3 activation by blocking K48-linked ubiquitination degradation of HO-1 to enhance type I interferons expression. Furthermore, a synthetic p21 peptide (amino acids 36 to 43) significantly inhibits IAV replication in vitro and in vivo. Collectively, our findings reveal that p21 restricts IAV by perturbing the viral polymerase complex and activating the host innate immune response, which may aid the design of desperately needed new antiviral therapeutics. Influenza A virus (IAV) poses a continuous threat to public health and economic stability. The ribonucleoprotein (RNP) of IAV is responsible for the transcription and replication of the viral RNA. These processes require interplay between host factors and RNP components. Here, we report that p21 can be activated by IAV infection and is controlled by a p53-independent pathway. We demonstrate that p21 directly binds to the viral polymerase acidic protein and limits IAV polymerase activity through disrupting the formation of the ribonucleoprotein complex. Additionally, p21 activation promotes IRF3 activation by blocking K48-linked polyubiquitination degradation of HO-1, thereby activating the type I interferon pathway. We further identify an 8-amino-acid peptide of p21 as the minimum motif that effectively inhibits IAV replication and presents therapeutic efficacy both in vitro and in vivo. Thus, our studies not only identify p21 as an antiviral protein, but also provide mechanistic insight to facilitate drug development.

CRISPR-Cas9 mediated knockout of AnxA6 gene enhances influenza A virus replication in low-permissive HEK293FT cell line. Gene 2022; 809:146024.

Abstract
Using cell cultures of human origin for the propagation of influenza virus is an attractive way to preserve its glycosylation profile and antigenic properties, which is essential in influenza surveillance and vaccine production. However, only few cell lines are highly permissive to influenza virus, and none of them are of human origin. The barrier might be associated with host restriction factors inhibiting influenza growth, such as AnxA6 protein counteracting the process of influenza virion packaging. In the presented work we explore the CRISPR-Cas9 mediated knockout of ANXA6 gene as a way to overcome the host restriction barrier and increase the susceptibility of human cell line to influenza infection. By CRISPR-Cas9 genome editing we modified HEK293FT cells and obtained several clones defective in the ANXA6 gene. The replication of the influenza A virus in original HEK293FT cells and the HEK293FT-ANXA6-/- mutant cells was compared in growth curve experiments. By combination of methods including TCID assay and flow cytometry we showed that accumulation of influenza A virus in the mutant HEK293FT-ANXA6-/- cells significantly exceeded the virus titer in the original HEK293FT cells.

Abstract
Influenza A virus (IAV), like other viruses, depends on the host cellular machinery for replication and production of progeny. The relationship between a virus and a host is complex, shaped by many spatial and temporal interactions between viral and host proteome, ultimately dictating disease outcome. Therefore, it is imperative to identify host-virus interactions as crucial determinants of disease pathogenies. Heterogeneous ribonucleoprotein A1 (hnRNPA1) is an RNA binding protein involved in the life cycle of many DNA and RNA viruses; however, its role in IAV remains undiscovered. Here we report that human hnRNPA1 physically interacts with the nucleoprotein (NP) of IAV in mammalian cells at different time points of the viral replication cycle. Temporal distribution studies identify hnRNPA1 and NP co-localize in the same cellular milieu in both nucleus and mitochondria in NP-transfected and IAV-infected mammalian cells. Interestingly, hnRNPA1 influenced NP gene expression and affected viral replication. Most importantly, hnRNPA1 knockdown caused a significant increase in NP expression and enhanced viral replication (93.82%) in IAV infected A549 cells. Conversely, hnRNPA1 overexpression reduced NP expression at the mRNA and protein levels and impeded virus replication by (60.70%), suggesting antagonistic function. Taken together, results from this study demonstrate that cellular hnRNPA1 plays a protective role in the host hitherto unknown and may hold potential as an antiviral target to develop host-based therapeutics against IAV.

Abstract
Background Replication of the influenza A viruses occurs in the cells through the viral RdRP consisting of PB1, PB2, and PA. Several cellular proteins are involved in these processes. This study aims to reveal the interaction between human SNX2 protein and the PA protein and the effects of the SNX2 on the virus replication. Results To identify potential host interacting proteins to the PA, yeast two-hybrid assay was carried out with HEK293 cell cDNA library and the PA as a bait. We focused on SNX2 protein, which interacts with the PA in the yeast cells. By using the co-immunoprecipitation assays, it has been demonstrated that the amino-terminal part of the PA was important for binding to the SNX2. Immunolocalization of the proteins in HeLa cells supported this interaction. Knockdown of the SNX2 with siRNA in the cells resulted in a significant increase in both viral transcripts and virus growth. However, the increase of SNX2 in transfected cells didn’t cause a significant change in the viral RdRP activity in minireplicon assay. This may suggest that the negative effect of SNX2 on the virus replication could be saturated with its authentic intra-cellular amount. Conclusions This study revealed that the SNX2 and PA protein interact with each other in both yeast and HEK293 cells, and the SNX2 has a negative regulatory function on the virus replication. However, more knowledge is required to elucidate the action mechanism of the SNX2 on the influenza A virus replication at the molecular level.

How Influenza A Virus NS1 Deals with the Ubiquitin System to Evade Innate Immunity. Viruses 2021; 13:v13112309. [PMID: 34835115 PMCID: PMC8619935 DOI: 10.3390/v13112309] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Revised: 11/14/2021] [Accepted: 11/18/2021] [Indexed: 12/11/2022] Open
Abstract
Ubiquitination is a post-translational modification regulating critical cellular processes such as protein degradation, trafficking and signaling pathways, including activation of the innate immune response. Therefore, viruses, and particularly influenza A virus (IAV), have evolved different mechanisms to counteract this system to perform proper infection. Among IAV proteins, the non-structural protein NS1 is shown to be one of the main virulence factors involved in these viral hijackings. NS1 is notably able to inhibit the host's antiviral response through the perturbation of ubiquitination in different ways, as discussed in this review.

An Integrated Analysis Reveals Geniposide Extracted From Gardenia jasminoides J.Ellis Regulates Calcium Signaling Pathway Essential for Influenza A Virus Replication. Front Pharmacol 2021; 12:755796.

Abstract
Geniposide, an iridoid glycoside purified from the fruit of Gardenia jasminoides J.Ellis, has been reported to possess pleiotropic activity against different diseases. In particular, geniposide possesses a variety of biological activities and exerts good therapeutic effects in the treatment of several strains of the influenza virus. However, the molecular mechanism for the therapeutic effect has not been well defined. This study aimed to investigate the mechanism of geniposide on influenza A virus (IAV). The potential targets and signaling pathways of geniposide in the IAV infection were predicted using network pharmacology analysis. According to the result of network pharmacology analysis, we validated the calcium signaling pathway induced by IAV and investigated the effect of geniposide extracted from Gardenia jasminoides J.Ellis on this pathway. The primary Gene Ontology (GO) biological processes and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways KEGG enrichment analysis indicated that geniposide has a multi-target and multi-pathway inhibitory effect against influenza, and one of the mechanisms involves calcium signaling pathway. In the current study, geniposide treatment greatly decreased the levels of RNA polymerase in HEK-293T cells infected with IAV. Knocking down CAMKII in IAV-infected HEK-293T cells enhanced virus RNA (vRNA) production. Geniposide treatment increased CAMKII expression after IAV infection. Meanwhile, the CREB and c-Fos expressions were inhibited by geniposide after IAV infection. The experimental validation data showed that the geniposide was able to alleviate extracellular Ca2+ influx, dramatically decreased neuraminidase activity, and suppressed IAV replication in vitro via regulating the calcium signaling pathway. These anti-IAV effects might be related to the disrupted interplay between IAV RNA polymerase and CAMKII and the regulation of the downstream calcium signaling pathway essential for IAV replication. Taken together, the findings reveal a new facet of the mechanism by which geniposide fights IAV in a way that depends on CAMKII replication.

Abstract
Infectious bursal disease virus (IBDV), a double-stranded RNA virus, causes immunosuppression and high mortality in 3-6-week-old chickens. Innate immune defense is a physical barrier to restrict viral replication. After viral infection, the host shows crucial defense responses, such as stimulation of antiviral effectors to restrict viral replication. Here, we conducted RNA-seq in avian cells infected by IBDV and identified TRIM25 as a host restriction factor. Specifically, TRIM25 deficiency dramatically increased viral yields, whereas overexpression of TRIM25 significantly inhibited IBDV replication. Immunoprecipitation assays indicated that TRIM25 only interacted with VP3 among all viral proteins, mediating its K27-linked polyubiquitination and subsequent proteasomal degradation. Moreover, the Lys854 residue of VP3 was identified as the key target site for the ubiquitination catalyzed by TRIM25. The ubiquitination site destroyed enhanced the replication ability of IBDV in vitro and in vivo. These findings demonstrated that TRIM25 inhibited IBDV replication by specifically ubiquitinating and degrading the structural protein VP3.

Abstract
The H1N1 influenza virus causes a severe disease that affects the human respiratory tract leading to millions of deaths every year. At present, certain vaccines and few drugs are used to control the virus during seasonal outbreaks. However, high mutation rates and genetic reassortment make it challenging to prevent and mitigate outbreaks, leading to pandemics. Thus, alternate therapies are required for its management and control. Here, we report that a bacterial protein, azurin, and its peptide derivatives p18 and p28 target critical proteins of the influenza virus in an effective manner. The molecular docking studies show that the p28 peptide could target C-PB1, NS1-ED, PB2-CBD, PB2-RBD, NP, and PA proteins. These complexes were further subjected to the simulation of molecular dynamics and binding free energy calculations. The data indicate that p28 has an unusually high affinity and forms stable complexes with the viral proteins C-PB1, PB2-CBD, PB2-RBD, and NP. We suggest that the azurin derivative p28 peptide can act as an anti-influenza agent as it can bind to multiple targets and neutralize the virus. Additional experimental studies need to be conducted to evaluate its safety and efficacy as an anti-H1N1 molecule.

Abstract
Influenza (flu) virus is a serious threat to global health with the potential to generate devastating pandemics. The availability of broad spectrum antiviral drugs is an unequaled weapon during pandemic events, especially when a vaccine is still not available. One of the most promising targets for the development of new antiflu therapeutics is the viral RNA-dependent RNA polymerase (RdRP). The assembly of the flu RdRP heterotrimeric complex from the individual polymerase acidic protein (PA), polymerase basic protein 1 (PB1), and polymerase basic protein 2 (PB2) subunits is a prerequisite for RdRP functions, such as mRNA synthesis and genome replication. In this Review, we report the known protein-protein interactions (PPIs) occurring by RdRP that could be disrupted by small molecules and analyze their benefits and drawbacks as drug targets. An overview of small molecules able to interfere with flu RdRP functions exploiting the PPI inhibition approach is described. In particular, an update on the most recent inhibitors targeting the well-consolidated RdRP PA-PB1 subunit heterodimerization is mainly reported, together with pioneer inhibitors targeting other virus-virus or virus-host interactions involving RdRP subunits. As demonstrated by the PA-PB1 interaction inhibitors discussed herein, the inhibition of flu RdRP functions by PPI disrupters clearly represents a valid means to identify compounds endowed with a broad spectrum of action and a reduced propensity to develop drug resistance, which are the main issues of antiviral drugs.

Improvement of PR8-Derived Recombinant Clade 2.3.4.4c H5N6 Vaccine Strains by Optimization of Internal Genes and H103Y Mutation of Hemagglutinin. Vaccines (Basel) 2020; 8:vaccines8040781.

Abstract
Clade 2.3.4.4c H5N6 avian influenza A viruses (AIVs) may have originally adapted to infect chickens and have caused highly pathogenic avian influenza (HPAI) in poultry and human fatalities. Although A/Puerto Rico/8/1934 (H1N1) (PR8)-derived recombinant clade 2.3.4.4c H5N6 vaccine strains have been effective in embryonated chicken eggs-based vaccine production system, they need to be improved in terms of immunogenicity and potential mammalian pathogenicity. We replaced the PB2 gene alone or the PB2 (polymerase basic protein 2), NP (nucleoprotein), M (matrix protein) and NS (non-structural protein) genes together in the PR8 strain with corresponding genes from AIVs with low pathogenicity to remove mammalian pathogenicity and to match CD8+ T cell epitopes with contemporary HPAI viruses, respectively, without loss of viral fitness. Additionally, we tested the effect of the H103Y mutation of hemagglutinin (HA) on antigen productivity, mammalian pathogenicity and heat/acid stability. The replacement of PB2 genes and the H103Y mutation reduced the mammalian pathogenicity but increased the antigen productivity of the recombinant vaccine strains. The H103Y mutation increased heat stability but unexpectedly decreased acid stability, probably resulting in increased activation pH for HA. Interestingly, vaccination with inactivated recombinant virus with replaced NP, M and NS genes halted challenge virus shedding earlier than the recombinant vaccine without internal genes replacement. In conclusion, we successfully generated recombinant clade 2.3.4.4c H5N6 vaccine strains that were less pathogenic to mammals and more productive and heat stable than conventional PR8-derived recombinant strains by optimization of internal genes and the H103Y mutation of HA.

Abstract
Influenza A virus (IAV) is a segmented, negative single-stranded RNA virus that causes seasonal epidemics and has a potential for pandemics. Several viral proteins are not packed in the IAV viral particle and only expressed in the infected host cells. These proteins are named non-structural proteins (NSPs), including NS1, PB1-F2 and PA-X. They play a versatile role in the viral life cycle by modulating viral replication and transcription. More importantly, they also play a critical role in the evasion of the surveillance of host defense and viral pathogenicity by inducing apoptosis, perturbing innate immunity, and exacerbating inflammation. Here, we review the recent advances of these NSPs and how the new findings deepen our understanding of IAV–host interactions and viral pathogenesis.

Abstract
The ubiquitin-proteasome system (UPS) has been recognized for regulating fundamental cellular processes, followed by induction of proteasomal degradation of target proteins, and triggers multiple signaling pathways that are crucial for numerous aspects of cellular physiology. Especially tripartite motif (TRIM) proteins, well-known E3 ubiquitin ligases, emerge as having critical roles in several antiviral signaling pathways against varying viral infections. Here we highlight recent advances in the study of antiviral roles of TRIM proteins toward influenza virus infection in terms of the modulation of pathogen recognition receptor (PRR)-mediated innate immune sensing, direct obstruction of influenza viral propagation, and participation in virus-induced autophagy.

Abstract
BACKGROUND Influenza A virus (IAV) infection is a serious public health problem not only in South East Asia but also in European and African countries. Scientists are using network biology to dig deep into the essential host factors responsible for regulation of virus infections. Researchers can explore the virus invasion into the host cells by studying the virus-host relationship based on their protein-protein interaction network. METHODS In this study, we present a comprehensive IAV-host protein-protein interaction network that is obtained based on the literature-curated protein interaction datasets and some important interaction databases. The network is constructed in Cytoscape and analyzed with its plugins including CytoHubba, CytoCluster, MCODE, ClusterViz and ClusterOne. In addition, Gene Ontology and KEGG enrichment analyses are performed on the highly IAV-associated human proteins. We also compare the current results with those from our previous study on Hepatitis C Virus (HCV)-host protein-protein interaction network in order to find out valuable information. RESULTS We found out 1027 interactions among 829 proteins of which 14 are viral proteins and 815 belong to human proteins. The viral protein NS1 has the highest number of associations with human proteins followed by NP, PB2 and so on. Among human proteins, LNX2, MEOX2, TFCP2, PRKRA and DVL2 have the most interactions with viral proteins. Based on KEGG pathway enrichment analysis of the highly IAV-associated human proteins, we found out that they are enriched in the KEGG pathway of basal cell carcinoma. Similarly, the result of KEGG analysis of the common host factors involved in IAV and HCV infections shows that these factors are enriched in the infection pathways of Hepatitis B Virus (HBV), Viral Carcinoma, measles and certain other viruses. CONCLUSION It is concluded that the list of proteins we identified might be used as potential drug targets for the drug design against the infectious diseases caused by Influenza A Virus and other viruses.

Abstract
Influenza A virus (IAV) is a highly transmissible respiratory pathogen and is a constant threat to global health with considerable economic and social impact. Influenza viral RNA is sensed by host pattern recognition receptors (PRRs), such as the Toll-like receptor 7 (TLR7) and retinoic acid-inducible gene I (RIG-I). The activation of these PRRs instigates the interferon regulatory factor (IRF) and nuclear factor kappa B (NF-κB) signaling pathways that induce the expression of interferon-stimulated genes (ISGs) and inflammatory genes. FK506-binding protein 5 (FKBP5) has been implied in the IκBα kinase (IKK) complex. However, the role of FKBP5 in the RIG-I signaling and IAV infection is not well elucidated. Here, we demonstrate that the knockout of FKBP5 increases IAV infection. Furthermore, FKBP5 binds IKKα, which is critical for RIG-I-induced innate immune responses and ISG expression. Taken together, FKBP5 is a novel anti-influenza host factor that restricts IAV infection by the activation of RIG-I-mediated NF-κB signaling.

Abstract
Vesicular stomatitis virus (VSV) is a zoonotic, negative-stranded RNA virus of the family Rhabdoviridae. The nucleoprotein (N) of VSV protects the viral genomic RNA and plays an essential role in viral transcription and replication, which makes the nucleoprotein an ideal target of host defense. However, whether and how host innate/intrinsic immunity limits VSV infection by targeting the N protein are unknown. In this study, we found that the N protein of VSV (VSV-N) interacted with a ubiquitin E3 ligase, tripartite motif protein 41 (TRIM41). Overexpression of TRIM41 inhibited VSV infection. Conversely, the depletion of TRIM41 increased host susceptibility to VSV. Furthermore, the E3 ligase defective mutant of TRIM41 failed to limit VSV infection, suggesting the requirement of the E3 ligase activity of TRIM41 in viral restriction. Indeed, TRIM41 ubiquitinated VSV-N in cells and in vitro. TRIM41-mediated ubiquitination leads to the degradation of VSV-N through proteasome, thereby limiting VSV infection. Taken together, our study identifies TRIM41 as a new intrinsic immune factor against VSV by targeting the viral nucleoprotein for ubiquitination and subsequent protein degradation.

Abstract
Viral infection is a complex pathogenesis and the underlying molecular mechanisms remain poorly understood. In this study, an integrated multiple resources analysis was performed and showed that the cellular ncRNAs and proteins targeted by viruses were primarily "hubs" and "bottlenecks" in the human ncRNA/protein-protein interaction. The common proteins targeted by both viral ncRNAs and proteins tended to skew toward higher degrees and betweenness compared with other proteins, showed significant enrichment in the cell death process. Specifically, >800 pairs of human cellular ncRNAs and viral ncRNAs that exhibited a high degree of functional homology were identified, representing potential ncRNA-mediated co-regulation patterns of viral invasion. Additionally, clustering analysis further revealed several distinct viral clusters with obvious functional divergence. Overall, this is the first attempt to systematically explore the invasive mechanism via global ncRNA-associated virus-host crosstalk. Our results provide useful information in comprehensively understanding the viral invasive mechanism.

Influenza A Virus Protein NS1 Exhibits Strain-Independent Conformational Plasticity. J Virol 2019; 93:JVI.00917-19.

Abstract
Influenza A virus (IAV) nonstructural protein 1 (NS1), a potent antagonist of the host immune response, is capable of interacting with RNA and a wide range of cellular proteins. NS1 consists of an RNA-binding domain (RBD) and an effector domain (ED) separated by a flexible linker region (LR). H5N1-NS1 has a characteristic 5-residue deletion in the LR, with either G (minor group) or E (major group) at the 71st position, and non-H5N1-NS1 contains E71 with an intact linker. Based on the orientation of the ED with respect to the RBD, previous crystallographic studies have shown that minor group H5N1-NS1(G71), a non-H5N1-NS1 [H6N6-NS1(E71)], and the LR deletion mutant H6N6-NS1(Δ80-84/E71) mimicking the major group H5N1-NS1 exhibit "open," "semiopen," and "closed" conformations, respectively, suggesting that NS1 exhibits a strain-dependent conformational preference. Here we report the first crystal structure of a naturally occurring H5N1-NS1(E71) and show that it adopts an open conformation similar to that of the minor group of H5N1-NS1 [H5N1-NS1(G71)]. We also show that H6N6-NS1(Δ80-84/E71) under a different crystallization condition and H6N6-NS1(Δ80-84/G71) also exhibit open conformations, suggesting that NS1 can adopt an open conformation irrespective of E or G at the 71st position. Our single-molecule fluorescence resonance energy transfer (FRET) analysis to investigate the conformational preference of NS1 in solution showed that all NS1 constructs predominantly exist in an open conformation. Further, our coimmunoprecipitation and binding studies showed that they all bind to cellular factors with similar affinities. Taken together, our studies suggest that NS1 exhibits strain-independent structural plasticity that allows it to interact with a wide variety of cellular ligands during viral infection.IMPORTANCE IAV is responsible for several pandemics over the last century and continues to infect millions annually. The frequent rise in drug-resistant strains necessitates exploring novel targets for developing antiviral drugs that can reduce the global burden of influenza infection. Because of its critical role in the replication and pathogenesis of IAV, nonstructural protein 1 (NS1) is a potential target for developing antivirals. Previous studies suggested that NS1 adopts strain-dependent "open," "semiopen," and "closed" conformations. Here we show, based on three crystal structures, that NS1 irrespective of strain differences can adopt an open conformation. We further show that NS1 from different strains primarily exists in an open conformation in solution and binds to cellular proteins with a similar affinity. Together, our findings suggest that conformational polymorphism facilitated by a flexible linker is intrinsic to NS1, and this may be the underlying factor allowing NS1 to bind several cellular factors during IAV replication.

Abstract
The complex nature and structure of the human immunodeficiency virus has rendered the cure for HIV infections elusive. The advances in antiretroviral treatment regimes and the development of highly advanced anti-retroviral therapy, which primarily targets the HIV enzymes, have dramatically changed the face of the HIV epidemic worldwide. Despite this remarkable progress, patients treated with these drugs often witness inadequate efficacy, compound toxicity and non-HIV complications. Considering the limited inventory of druggable HIV proteins and their susceptibility to develop drug resistance, recent attempts are focussed on targeting HIV-host interactomes that are essential for viral reproduction. Noticeably, unlike other viruses, HIV subverts the host nuclear pore complex to enter into and exit through the nucleus. Emerging evidence suggests a crucial role of interactions between HIV-1 proteins and host nucleoporins that underlie the import of the pre-integration complex into the nucleus and export of viral RNAs into the cytoplasm during viral replication. Nevertheless, the interaction of HIV-1 with nucleoporins has been poorly described and the role of nucleoporins during nucleocytoplasmic transport of HIV-1 still remains unclear. In this review, we highlight the advances and challenges in developing a more effective antiviral arsenal by exploring critical host-HIV interactions with a special focus on nuclear pore complex (NPC) and nucleoporins.

Abstract
Viral diseases represent one of the major threats for salmonid aquaculture. Survival from viral infections are highly dependent on host innate antiviral immune defense, where interferons are of crucial importance. Neutralizing antibodies and T cell effector mechanisms mediate long-term antiviral protection. Despite an immune cell repertoire comparable to higher vertebrates, farmed fish often fail to mount optimal antiviral protection. In the quest to multiply and spread, viruses utilize a variety of strategies to evade or escape the host immune system. Understanding the specific interplay between viruses and host immunity at depth is crucial for developing successful vaccination and treatment strategies in mammals. However, this knowledge base is still limited for pathogenic fish viruses. Here, we have focused on five RNA viruses with major impact on salmonid aquaculture: Salmonid alphavirus, Infectious salmon anemia virus, Infectious pancreatic necrosis virus, Piscine orthoreovirus and Piscine myocarditis virus. This review explore the protective immune responses that salmonids mount to these viruses and the existing knowledge on how the viruses counteract and/or bypass the immune response, including their IFN antagonizing effects and their mechanisms to establish persisting infections.

Abstract
H5N1 influenza A virus (IAV) causes seasonal epidemics that represent a worldwide threat to public health. IAV relies on host factors for viral replication. PB1 N40 is translated from the fifth starting code (AUG) of PB1 mRNA, which is the product of the ribosomal scan omission. Here, we report the interactome landscape of H5N1 IAV PB1 N40 protein in chicken cells. The interacting complexes were captured by co-immunoprecipitation and analyzed by mass spectrometry. We identified 135 proteins as PB1 N40-interacting proteins. GO and Pathway analysis showed that proteins with biological functions such as protein localization and viral transcription and proteins related to signaling pathways of DNA replication and cell cycle were significantly enriched in virus-host interactions, suggesting the potential roles of them in infection with H5N1 IAV. Comparative analysis among H1N1 and H5N1 revealed conservation of the virus-host protein interaction between different subtypes or strains of influenza virus. ARCN1 was identified as a host interacting factor of H5N1 IAV PB1 N40 protein, which is the component of the coatomer. Knockdown of ARCN1 significantly decreased the titer of H5N1 IAV in chicken cells. BIOLOGICAL SIGNIFICANCE: Influenza A virus (IAV) is a great threat to public health and avian production. However, the manner in which avian IAV recruits the host cellular machinery for replication and how the host antagonizes the IAV infection was previously poorly understood. Here we present the viral-host interactome of the H5N1 IAV PB1 N40 protein and reveal its involvement with dozens of important host genes during the course of IAV infection.

Wei X, Liu Z, Wang J, Yang R, Yang J, Guo Y, Tan H, Chen H, Liu Q, Liu L. The interaction of cellular protein ANP32A with influenza A virus polymerase component PB2 promotes vRNA synthesis. Arch Virol 2019; 164:787-798. [PMID: 30666459 DOI: 10.1007/s00705-018-04139-z] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2018] [Accepted: 11/23/2018] [Indexed: 12/13/2022]
Abstract
The subunits PA, PB1, and PB2 of influenza A virus RNA polymerase are essential for efficient viral RNA synthesis and virus replication because of their role in recruiting multiple nuclear proteins. ANP32A is an acidic leucine-rich nuclear phosphoprotein 32 (ANP32) family member and a crucial cellular protein that determines the species specificity of the influenza virus RNA polymerase activity. However, how ANP32A modulates polymerase activity remains largely unknown. In this study, we showed that viral RNA synthesis was increased in A549 cells overexpressing ANP32A and decreased after treatment with ANP32A RNAi. This decrease in RNA synthesis was reversed by rescued ANP32A expression. The results of docking modeling, co-immunoprecipitation, and yeast two-hybrid assays showed that PB2 was the only subunit of the three that interacted with ANP32A. The C-terminal portion of ANP32A and the middle domains (residues 307-534) of PB2 were required for PB2-ANP32A interaction. Glu189 and Glu196 in ANP32A and Gly450 and Gln447 in PB2 were essential for interaction between ANP32A and PB2. These residues were located in conserved regions of the ANP32A or PB2 protein sequences. These data suggest that ANP32A is recruited to the polymerase through direct interaction with PB2 via critical amino acid residue interactions and promotes viral RNA synthesis. Our findings might provide new insights into the molecular mechanisms underlying influenza virus RNA synthesis and replication in infected human cells.

Abstract
BST2 is an antiviral factor that inhibits the release of enveloped virus at the plasma membrane via an unusual topology in which its N-terminal is in the cytosol while its C-terminal is anchored by glycophosphatidylinositol (GPI). BST2-deficient cells showed substantially higher release of virions than wild type cells. Influenza-infected BST2-deficient cells showed greatly reduced cytopathic effect (CPE) than wild type cells despite their generally robust virus production. This finding prompted us to determine whether BST2 was involved in the apoptotic process of virus-infected host cells. Our results revealed that BST2 might be involved in IRE1α-mediated ER stress pathway by increasing spliced form XBP-1. Consequently, levels of cytochrome C, caspase-3, caspase-9, and PARP as representative molecules of apoptosis were significantly increased in wild type cells than those in BST2-deficient cells. These results suggest that BST2 might participate in innate host defense by augmenting ER-stress-induced apoptotic signaling to inhibit the replication and spread of virus.

Abstract
Grail is a well-characterized mediator of metabolic disease, tumour progression, and immune response. However, its role in influenza A virus (IAV) infection remains poorly understood. In this study, we demonstrated that Grail knockdown potentiates IAV infection, whereas Grail overexpression blocks IAV replication. The intranasal administration of IAV to Grail KO mice led to a lower survival rate than in similarly infected wild-type mice. Additionally, IAV-infected Grail KO mice had higher viral titres, greater immune cell infiltration, and increased expression of inflammatory cytokines in the lungs. Mechanistically, we showed that Grail interacts with viral nucleoprotein (NP), targeting it for degradation and inhibiting IAV replication. NP expression was increased in Grail knockdown cells and reduced in cells overexpressing Grail. Collectively, our results demonstrate that Grail acts as a negative regulator of IAV infection and replication by degrading viral NP. These data increase our understanding of the host antiviral response to infection with IAV.

Abstract
The basic affairs connected to the influenza virus were reviewed in the article, highlighting the newest trends in its diagnostic methods. Awareness of the threat of influenza arises from its ability to spread and cause a pandemic. The undiagnosed and untreated viral infection can have a fatal effect on humans. Thus, the early detection seems pivotal for an accurate treatment, when vaccines and other contemporary prevention methods are not faultless. Public health is being attacked with influenza containing new genes from a genetic assortment between animals and humankind. Unfortunately, the population does not have immunity for mutant genes and is attacked in every viral outbreak season. For these reasons, fast and accurate devices are in high demand. As currently used methods like Rapid Influenza Diagnostic Tests lack specificity, time and cost-savings, new methods are being developed. In the article, various novel detection methods, such as electrical and optical were compared. Different viral elements used as detection targets and analysis parameters, such as sensitivity and specificity, were presented and discussed.

TRIM41-Mediated Ubiquitination of Nucleoprotein Limits Influenza A Virus Infection. J Virol 2018; 92:JVI.00905-18.

Abstract
Influenza A virus (IAV) is a highly transmissible respiratory pathogen and a major cause of morbidity and mortality around the world. Nucleoprotein (NP) is an abundant IAV protein essential for multiple steps of the viral life cycle. Our recent proteomic study of the IAV-host interaction network found that TRIM41 (tripartite motif-containing 41), a ubiquitin E3 ligase, interacted with NP. However, the role of TRIM41 in IAV infection is unknown. Here, we report that TRIM41 interacts with NP through its SPRY domain. Furthermore, TRIM41 is constitutively expressed in lung epithelial cells, and overexpression of TRIM41 inhibits IAV infection. Conversely, RNA interference (RNAi) and knockout of TRIM41 increase host susceptibility to IAV infection. As a ubiquitin E3 ligase, TRIM41 ubiquitinates NP in vitro and in cells. The TRIM41 mutant lacking E3 ligase activity fails to inhibit IAV infection, suggesting that the E3 ligase activity is indispensable for TRIM41 antiviral function. Mechanistic analysis further revealed that the polyubiquitination leads to NP protein degradation and viral inhibition. Taking these observations together, TRIM41 is a constitutively expressed intrinsic IAV restriction factor that targets NP for ubiquitination and protein degradation.IMPORTANCE Influenza control strategies rely on annual immunization and require frequent updates of the vaccine, which is not always a foolproof process. Furthermore, the current antivirals are also losing effectiveness as new viral strains are often refractory to conventional treatments. Thus, there is an urgent need to find new antiviral mechanisms and develop therapeutic drugs based on these mechanisms. Targeting the virus-host interface is an emerging new strategy because host factors controlling viral replication activity will be ideal candidates, and cellular proteins are less likely to mutate under drug-mediated selective pressure. Here, we show that the ubiquitin E3 ligase TRIM41 is an intrinsic host restriction factor to IAV. TRIM41 directly binds the viral nucleoprotein and targets it for ubiquitination and proteasomal degradation, thereby limiting viral infection. Exploitation of this natural defense pathway may open new avenues to develop antiviral drugs targeting the influenza virus.

Abstract
MicroRNAs (miRNAs) are small noncoding RNA molecules that play important roles in various biological processes. Much evidence shows that miRNAs are closely associated with numerous virus infections; however, involvement of cellular miRNAs in influenza A virus (IAV) infection is unclear. Here, we found that expression of miR-203 was up-regulated markedly via two different mechanisms during IAV infection. First, we examined the effects of type I interferon induced by IAV on direct activation of miR-203 expression. Next, we showed that DNA demethylation within the miR-203 promoter region in A549 cells induced its up-regulation, and that expression of DNA methyltransferase 1 was down-regulated following H5N1 virus infection. Ectopic expression of miR-203 in turn inhibited H5N1 virus replication by targeting down-regulator of transcription 1 (DR1), which was identified as a novel target of miR-203. Silencing DR1 in miR-203 knockout cells using a specific siRNA inhibited replication of the H5N1 virus, an effect similar to that of miR-203. In summary, the data show that host cell expression of miR-203 is up-regulated upon IAV infection, which increases antiviral responses by suppressing a novel target gene, DR1. Thus, we have identified a novel mechanism underlying the relationship between miR-203 and IAV infection.

Abstract
An interferon-mediated antiviral protein, 2'-5' oligoadenylate synthetase 2, plays an important role in the antiviral response of interferons. In this study, 2'-5' oligoadenylate synthetase 2 genes were cloned from Chinese domestic pigs. Bioinformatics analysis revealed that the 2024-bp long open reading fame encodes 707 amino acids. There are two conserved regions in this protein: the nucleotidyltransferase domain, and the 2'-5' oligoadenylate synthetase domain (OAS). Genetic evolution analysis showed that the 2'-5' oligoadenylate synthetase 2 gene in domestic pigs is closely related to that of cattle. There are multiple antigenic sites, no signal peptide, and no transmembrane region in the gene, which is predicted to be a hydrophilic protein. Secondary structures were found to be mainly alpha helix-based; its tertiary structure is close to that of humans and cattle, but not that of mice. Tissue distribution results indicated that this protein is distributed in multiple organs, with high distribution in the liver; it is mainly localized in the cytoplasm. PRRSV infection, interferon-beta, and Poly(I: C) treatment all promoted 2'-5' oligoadenylate synthetase 2 gene expression. Overexpression and RNA silencing of porcine OAS2 inhibited and promoted PRRSV replication in cells, respectively. The inhibitory effect of porcine OAS2 was mainly dependent on RNase L, similar to what was predicted. This study has laid the foundation for future antiviral studies in pig, and provided a new way of preventing and treating PRRSV in the future.

Abstract
The 701 and 702 positions of influenza PB2 polymerase subunit are previously shown to have roles on host range. Limited polymorphisms at these two residues are identified in natural isolates, thereby limiting the study of their role in the polymerase. In this study, we generated 31 viable viruses by random mutagenesis at this region, indicating that these positions can tolerate a wide range of amino acids. These mutants demonstrated varying polymerase activities and viral replication rates in mammalian and avian cells. Notably, some mutants displayed enhanced polymerase activity, yet their replication kinetics were comparable to the wild-type virus. Surface electrostatic charge predication on the PB2 structural model revealed that the viral polymerase activity in mammalian cells generally increases as this region becomes more positively charged. One of the mutants (701A/702E) showed much reduced pathogenicity in mice while others had a pathogenicity similar to the wild-type level. Distinct tissue tropisms of the PB2-701/702 mutants were observed in infected chicken embryos. Overall, this study demonstrates that the PB2-701/702 region has a high degree of sequence plasticity and sequence changes in this region can alter virus phenotypes in vitro and in vivo.

Abstract
Porcine reproductive and respiratory syndrome virus (PRRSV) is acknowledged a fulminating infectious pathogen affecting the pig farming industry, and current vaccines and drugs could hardly inhibit this virus. The 2', 5'-oligoadenylate synthetase (OASs) have antiviral activities, but the role(s) played by porcine OAS2 in protection against PRRSV infection are unknown. Here we found that endogenous expression of the porcine OAS2 gene could be promoted by interferon (IFN)-beta or PRRSV infection in porcine alveolar macrophages. Knockdown of porcine OAS2 led to increases in PRRSV replication, and OAS2 expression suppressed replication of PRRSV in a retinoic acid inducible gene I (RIG-I)-dependent manner, anti-PRRSV activity of porcine OAS2 would be lost if RNase L and OAS2 were both silenced. This discovery illustrates a pathway that porcine OAS2 responses to host anti-PRRSV function.
