Abstract
Annexin A2 (ANXA2) is a multifaceted protein implicated in various stages of viral infections, particularly in envelope virus replication through mechanisms such as endocytosis and exocytosis. This study delves into the characterization and functional dynamics of duck ANXA2 (duANXA2). We successfully cloned the full-length coding sequence of duANXA2 and conducted a detailed structural analysis. The open reading frame (ORF) of duANXA2 is 1020 bp, encoding 339 amino acids and featuring 4 conserved domains. Phylogenetic tree analysis indicates that duANXA2 is most closely related to Gallus gallus, with significantly lesser homology to fish species. We evaluated the tissue-specific expression of duANXA2 in healthy ducks, noting its ubiquitous presence but varying expression levels across different organs, with notably high expression in the esophagus and immune organs. Upon infecting duck embryo fibroblast (DEF) cells with the duck Tembusu virus (DTMUV), a flavivirus causing ducks substantial mortality and a dramatic decline in egg production, we observed a pronounced upregulation of duANXA2. Functional assays demonstrated that overexpression of duANXA2 in DEF cells augments DTMUV replication, while its interference markedly reduces DTMUV replication. These findings underscore the role of duANXA2 as a facilitator of DTMUV replication, presenting it as a potential target for therapeutic intervention in managing DTMUV infections.

Abstract
Duck Tembusu Virus (DTMUV) is a pathogen of the Flaviviridae family that causes infections in poultry, leading to significant economic losses in the duck farming industry in recent years. Ducks infected with this virus exhibit clinical symptoms such as decreased egg production and neurological disorders, along with serious consequences such as ovarian hemorrhage, organ enlargement, and necrosis. Variations in morbidity and mortality rates exist across different age groups of ducks. It is worth noting that DTMUV is not limited to ducks alone; it can also spread to other poultry such as chickens and geese, and antibodies related to DTMUV have even been found in duck farm workers, suggesting a potential risk of zoonotic transmission. This article provides a detailed overview of DTMUV research, delving into its genomic characteristics, vaccines, and the interplay with host immune responses. These in-depth research findings contribute to a more comprehensive understanding of the virus's transmission mechanism and pathogenic process, offering crucial scientific support for epidemic prevention and control.

[PMID: 37951010 DOI: 10.1016/j.vetmic.2023.109907] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 10/26/2023] [Accepted: 10/27/2023] [Indexed: 11/13/2023]
Abstract
Laboratory of Genetics and Physiology 2 (LGP2), along with Retinoic Acid Induced Gene-I (RIG-I) and Melanoma Differentiation Associated Gene 5, are members of the retinoic acid-inducible gene-I-like receptors (RLRs) in pattern recognition receptors, playing an important role in the host's innate immunity. Due to lacking a caspase activation and recruitment domain, LGP2 is controversially regarded as a positive or negative regulator in the antiviral response. This study aimed to explore how duck LGP2 (duLGP2) participates in duck innate immunity and its role in countering the duck Tembusu virus (DTMUV). In duck embryo fibroblast cells, the overexpression of duLGP2 significantly reduced the cell's antiviral capacity by inhibiting type I interferon (IFN) production and the expression of downstream IFN-stimulated genes. Conversely, duLGP2 knockdown had the opposite effect. For the first time, we introduced the LGP2 gene fragment into duck embryos using a lentiviral vector to ensure persistent expression and generated gene-edited ducks with LGP2 overexpression. We demonstrated that duLGP2 facilitates DTMUV replication in both in vitro and in vivo experiments, leading to robust inflammatory and antiviral responses. Interestingly, the repressive effects of duLGP2 on type I IFN production were only observed in the early stage of DTMUV infection, with type I IFN responses becoming enhanced as the viral load increased. These results indicate that duLGP2 acts as a negative regulator during the resting state and early stages of DTMUV infection. This study provides a theoretical basis for further research on duck RLRs and developing new anti-DTMUV drugs or vaccine adjuvants.

Abstract
In mammals, the retinoic acid-inducible gene I (RIG-I)-like receptors (RLR) has been demonstrated to play a critical role in activating downstream signaling in response to viral RNA. However, its role in ducks’ antiviral innate immunity is less well understood, and how gene-mediated signaling is regulated is unknown. The regulatory role of the duck laboratory of genetics and physiology 2 (duLGP2) in the duck RIG-I (duRIG-I)-mediated antiviral innate immune signaling system was investigated in this study. In duck embryo fibroblast (DEF) cells, overexpression of duLGP2 dramatically reduced duRIG-I-mediated IFN-promotor activity and cytokine expression. In contrast, the knockdown of duLGP2 led to an opposite effect on the duRIG-I-mediated signaling pathway. We demonstrated that duLGP2 suppressed the duRIG-I activation induced by duck Tembusu virus (DTMUV) infection. Intriguingly, when duRIG-I signaling was triggered, duLGP2 enhanced the production of inflammatory cytokines. We further showed that duLGP2 interacts with duRIG-I, and this interaction was intensified during DTMUV infection. In summary, our data suggest that duLGP2 downregulated duRIG-I mediated innate immunity against the Tembusu virus. The findings of this study will help researchers better understand the antiviral innate immune system’s regulatory networks in ducks.

Abstract
Duck Tembusu virus (DTMUV), a member of the family Flaviviridae and an economically important pathogen with a broad host range, leads to markedly decreased egg production. However, the molecular mechanism underlying the host-DTMUV interaction remains unclear. Here, we performed high-throughput RNA sequencing (RNA-Seq) to study the dynamic changes in host gene expression at 12, 24, 36, 48 and 60 h post-infection (hpi) in duck embryo fibroblasts (DEF) infected with DTMUV. A total of 3129 differentially expressed genes (DEG) were identified after DTMUV infection. Gene Ontology (GO) category and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis revealed that these DEG were associated with multiple biological functions, including signal transduction, host immunity, virus infection, cell apoptosis, cell proliferation, and pathogenicity-related and metabolic process signaling pathways. This study analyzed viral infection and host immunity induced by DTMUV infection from a novel perspective, and the results provide valuable information regarding the mechanisms underlying host-DTMUV interactions, which will prove useful for the future development of antiviral drugs or vaccines for poultry, thus benefiting the entire poultry industry.

Abstract
Duck hepatitis A virus type 1 (DHAV-1) is a highly lethal virus that severely affects the duck industry worldwide. Long noncoding RNAs (lncRNAs) exert crucial roles in pathogen attacks. Here, we conducted deep transcriptome analysis to investigate the dynamic changes of host lncRNAs profiles in DHAV-1-infected duck embryo fibroblasts. We identified 16,589 lncRNAs in total and characterized their genomic features. Moreover, 772 and 616 differentially expressed lncRNAs (DELs) were screened at 12 and 24 h post-infection. Additionally, we predicted the DELs’ cis- and trans-target genes and constructed lncRNA-target genes regulatory networks. Functional annotation analyses indicated that the putative target genes of DELs participated in diverse vital biological processed, including immune responses, cellular metabolism, and autophagy. For example, we confirmed the dysregulation of pattern recognition receptors (TLR3, RIG-I, MDA5, LGP2, cGAS), signal transducers (STAT1), transcription factors (IRF7), immune response mediators (IL6, IL10, TRIM25, TRIM35, TRIM60, IFITM1, IFITM3, IFITM5), and autophagy-related genes (ULK1, ULK2, EIF4EBP2) using RT-qPCR. Finally, we confirmed that one DHAV-1 induced lncRNA-XR_003496198 is likely to inhibit DHAV-1 replication in DEFs. Our study comprehensively analyzed the lncRNA profiles upon DHAV-1 infection and screened the target genes involved in the innate immune response and autophagy signaling pathway, thereby revealing the essential roles of duck lncRNAs and broadening our understanding of host-virus interactions.

Abstract
Despite autophagy’s pivotal role in the replication of viruses such as duck Tembusu virus (DTMUV), which has caused massive economic losses to the poultry industry in the world, the specific relationships between DTMUV and cellular autophagy remain largely unknown. In response, we investigated the interactions between autophagy and DTMUV, the effects of the structural and non-structural proteins of DTMUV on autophagy, and the autophagy-related signaling pathways induced by DTMUV. Among the results, DTMUV increased the autophagy flux in duck embryo fibroblasts (DEF) and BHK-21 cells, while autophagy facilitated viral replication. After we pharmacologically induced autophagy with rapamycin (RAPA), the replication of DTMUV increased by 15.23-fold compared with the control group of DEF cells. To identify which DTMUV protein primarily induced autophagy, all three structural proteins and seven non-structural proteins of DTMUV were transfected into cells, and the results showed that non-structural protein 3 (NS3) induced significant autophagy in DEF cells. By means of Western blot, immunofluorescence, and transmission electron microscopy, we confirmed that NS3 protein could significantly induce autophagy and autophagy flux. Furthermore, we showed that NS3 induced autophagy in DEF cells through extracellular signal-regulated kinase 2 (ERK2) and phosphatidylinositol-3-kinase (PI3K)/AKT and the mammalian target of rapamycin (mTOR) signaling pathways using specific inhibitors and RNA interference assays. Finally, autophagy induced by NS3 promoted DTMUV replication. These results provide novel insight into the relationship between DTMUV and autophagy, broadening the current understanding of the molecular pathogenesis of DTMUV.

Abstract
A comprehensive study on the pathogenicity and host immune response was conducted in White Pekin ducklings after experimental infection with an Indian isolate of duck enteritis virus (DEV). The virus was found to be highly pathogenic and pantropic, which rapidly multiplied in various organs, mainly in the spleen and liver showing higher viral load with severe pathological lesions and caused 100% mortality. Expression profiles of immune gene transcripts in tissues (liver, spleen, brain) revealed upregulation of proinflammatory cytokines IFN-α, IFN- β, IL-1β, IL-6 and also iNOS with stimulation of TLRs (TLR-2, 3, 21). IFN-α was robustly upregulated (p < 0.05) especially in liver, might be playing role in antiviral innate immunity. Further, massive upregulation of MHC class-I (p < 0.01), expression of Th1 cytokines (IFN-γ & IL-2) and certain Th2 cytokines (IL-4 & IL-10) suggests stimulation of cell mediated as well as humoral immunity. To our knowledge, we are reporting first time about the robust upregulation of MHC class-I in spleen, liver and brain along with expression of certain cytokines in the peripheral blood mononuclear cells (PBMCs) during experimental DEV infection.

Abstract
Duck Tembusu virus (DTMUV), an emerging avian pathogenic flavivirus, causes severe neurological disorders and acute egg drop syndrome in ducks. However, the effects of DTMUV on duck immunological components and functions remain largely unknown. In this study, the dynamics of cellular and humoral immune responses of DTMUV-infected ducks were investigated. The numbers of CD4+ and CD8+ T, B and non-T and B lymphocytes as well as the levels of neutralizing antibodies were quantified in parallel with DTMUV loads in blood and target organs. Our results demonstrated that DTMUV infection caused severe losses of non-T and B lymphocyte/myeloid cell subpopulation, and reduction in phagocytic activity during 3-5 days after infection. We also found that the numbers of T and B cells were increased during the first week of DTMUV infection. A significant negative correlation between the levels of CD4+ and CD8+ T, B and non-T and B lymphocytes and viral loads in blood and target organ (spleen) was observed during the early phase of infection. Additionally, DTMUV infection induced an early and robust neutralizing antibody response, which was associated with DTMUV-specific IgM and IgG responses. The presence of neutralizing antibody also correlated with reduction of viremia and viral load in spleen. Overall, DTMUV elicited both cellular and humoral immune responses upon infection, in which the magnitude of these responses was correlated with reduction of viremia and viral loads in the target organ (spleen). The results suggested the critical role of both cellular and humoral immunity against DTMUV infection. This study expands our understanding of the immunological events following DTMUV infection in ducks. This article is protected by copyright. All rights reserved.

Decreased virulence of duck Tembusu virus harboring a mutant NS2A with impaired interaction with STING and IFNβ induction. Vet Microbiol 2021; 265:109312. [PMID: 34953307 DOI: 10.1016/j.vetmic.2021.109312] [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: 09/30/2021] [Revised: 12/18/2021] [Accepted: 12/19/2021] [Indexed: 11/27/2022]
Abstract
Our previous studies revealed that duck Tembusu virus (DTMUV) NS2A inhibited IFNβ signaling pathway by competitively binding to STING with TBK1, leading to reducing the phosphorylation of TBK1. Herein, we found that the 114-143 aa region of NS2A is critical for its interaction with STING and suppression of STING-mediated IFNβ signaling. We further identified the amino acids at positions L129, N130, L139, R140 and F143 of NS2A critical for NS2A-STING interaction. Subsequently, single residue substitution in the NS2A protein was introduced into the DTMUV replicon and infectious clone. The replicons with NS2A L129A and L130A mutations significantly inhibited viral genome RNA replication. The rDTMUV NS2A L129A, L139A and R140A mutant viruses yielded significantly lower titer levels than WT in both BHK-21 and DEF cells, with much more obvious effect on the viral genome level, and infectious virions formed outside of infected cells. Especially, the rDTMUV L129A mutant showed a significantly lower mortality in both embryos and ducks than WT. All NS2A-mutants decreased the weight gain of infected ducklings and reduced the viral loads in the spleen relative to WT. However, no significant differences of viral loads were observed in the blood, thymus, or liver. Our findings extend our previous study on the immune evasion role of flavivirus NS2A protein. The targeted therapy of disabling the viral strategies developed for evading innate defense can be applied to the development of attenuated flaviviruses.

Regulation of MDA5-dependent anti-Tembusu virus innate immune responses by LGP2 in ducks. Vet Microbiol 2021; 263:109281.

Abstract
Melanoma differentiation associated factor 5 (MDA5), which belongs to the retinoic acid-inducible gene I (RIG-I)-like receptors (RLRs) family, has been proved to be a key pattern recognition receptor of innate antiviral signaling in duck, which plays an important role in anti-Tembusu virus (TMUV) infection. However, laboratory of genetics and physiology 2 (LGP2), the third member of RLRs family, the regulatory function on antiviral innate immunity of MDA5 is currently unclear. In this study, we investigated the subcellular localization of duck LGP2 (duLGP2) and confirmed that it is an important regulator of the duMDA5-mediated host innate antiviral immune response. The present experimental data demonstrate that the overexpression of duLGP2 inhibits duMDA5 downstream transcriptional factor (IRF-7, IFN-β, and NF-κB) promoter activity, and duMDA5-mediated type I IFNs and ISGs expression were significantly suppressed by duLGP2 regardless of viral infection in vitro. The inhibition of duLGP2 on the antiviral activity of duMDA5 ultimately leads to an increase in viral replication. However, the overexpression of duLGP2 promotes expression of mitochondrial antiviral-signaling protein (MAVS) and duMDA5-mediated proinflammatory cytokines. This study provides a new rationale support for the duLGP2 regulates duMDA5-mediated anti-viral immune signaling pathway theory in duck.

Abstract
Duck Tembusu virus (DTMUV), an emergent flavivirus, causes domestic waterfowls to suffer from severe egg-drop syndrome and fatal encephalitis, greatly threatens duck production globally. Like other mosquito-borne flaviviruses, the envelope (E) protein of all DTMUV strains was N-glycosylated at the amino acid position 154. Thus far, the biological roles of DTMUV E glycosylation have remained largely unexplored. Herein, we demonstrated the key roles of E glycosylation in the replication and pathogenicity of DTMUV in ducks by characterizing the reverse-genetics-derived DTMUV wild-type MC strain and MC bearing mutations (N154Q and N154I) that abolish the E glycosylation. Our data showed that the disruption of E glycosylation could substantially impair virus attachment, entry, and infectivity in DEFs and C6/36 cells. Notably, ducks inoculated intracerebrally with the wild-type virus exhibited severe disease onset. In contrast, those inoculated with mutant viruses were mildly affected as manifested by minimal weight loss, no mortality, lower viral loads in the various tissues, and reduced brain lesions. Attenuated phenotypes of the mutant viruses might be partly associated with lower inflammatory cytokines expression in the brains of infected ducks. Our study offers the first evidence that E glycosylation is vital for DTMUV replication, pathogenicity, and neurovirulence in vivo.

Abstract
Reported for the first time in 1955 in Malaysia, Tembusu virus (TMUV) remained, for a long time, in the shadow of flaviviruses with human health importance such as dengue virus or Japanese encephalitis virus. However, since 2010 and the first large epidemic in duck farms in China, the threat of its emergence on a large scale in Asia or even its spillover into the human population is becoming more and more significant. This review aims to report current knowledge on TMUV from viral particle organization to the development of specific vaccines and therapeutics, with a particular focus on host-virus interactions.

Abstract
Duck Tembusu virus (DTMUV) and Japanese encephalitis virus (JEV) are mosquito-borne flaviviruses. These two viruses infect ducks; however, they show different neurological outcomes. The mechanism of DTMUV- and JEV-induced neuronal death has not been well investigated. In the present study, we examined the differences in the mechanisms involved in virus-induced cell death and innate immune responses between DTMUV KPS54A61 strain and JEV JaGAr-01 strain using primary duck neurons (DN) and duck fibroblasts (CCL-141). DN and CCL-141 were permissive for the infection and replication of these two viruses, which upregulated the expression of innate immunity genes. Both DTMUV and JEV induced cell death via a caspase-3-dependent manner; however, DTMUV triggered more cell death than JEV did in both CCL-141 and DN. These findings suggest that DTMUV infection causes apoptosis in duck neurons and fibroblasts more strongly than JEV. Levels of the mRNA expression of innate immunity-related genes after DTMUV infection were generally higher than levels after JEV infection, suggesting that DTMUV-induced immune response in duck cells may exhibit toxic effect rather than protective effects.

Abstract
CD4 protein is a single chain transmembrane glycoprotein and has a broad functionality beyond cell-mediated immunity. In this study, we cloned the full-length coding sequence (CDS) of duck CD4 (duCD4) and analyzed its sequence and structure, and expression levels in several tissues. It consists of 1,449 nucleotides and encodes a 482 amino acid protein. The putative protein of duCD4 consisted of an N-terminal signal peptide, three immunoglobulins and one immunoglobulins-like domain in its central, one terminal transmembrane region, and a C-terminal domain of the CD4 T cell receptor. The duCD4 also has the typical signature “CXC” of CD4s. The multiple sequence alignment suggests duCD4 has four potential N-glycosylation sites and the phylogenetic analysis suggests duCD4 shares greater similarity with avian than other vertebrates. Quantitative real-time PCR analysis showed that duCD4 mRNA transcripts are widely distributed in the healthy Cherry Valley duck, and the highest level in the thymus. During the virus infection, the obvious change of duCD4 expression was observed in the spleen, lung and brain, which suggesting that duCD4 could be involved in the host's immune response to multiple types of viruses. Our research studied the characterization, tissue distribution, and antiviral immune responses of duCD4.

Abstract
Duck Tembusu virus (DTMUV), a neurotropic flavivirus, is a causative agent of severe
neurological diseases in different birds. No approved vaccines or antiviral therapeutic
treatments are available to date. The poultry industry experiences significant economic
losses due to DTMUV infections. Minocycline is a second-generation semi-synthetic
tetracycline analogue that is commonly used as an antimicrobial treatment. Experimental
studies have indicated the successful protective effects of minocycline against neuronal
cell death from neurodegenerative diseases and viral encephalitis. The aim of this study
was to investigate the effects of minocycline on DTMUV infection in neurons. Primary duck
neurons were treated with minocycline, which exhibited neuroprotective effects via
anti-apoptotic function rather than through viral replication inhibition. Minocycline
might serve as a potential effective drug in DTMUV infection.

Abstract
Tembusu Virus (TMUV), a pathogenic member of Flavivirus family, acts as the causative agent of egg-laying and has severely threatened the duck industry over the past few years. Thus far, the pathogenicity of such virus has been extensively studied, whereas TMUV on immune system has been less comprehensively assessed, especially on ducklings that exhibit more susceptible to TMUV attack. Accordingly, in the present study, 5-day-old ducklings were infected with TMUV-TC2B (104 TCID50) via intravenous injection, and mock ones were inoculated with phosphate-buffered saline (PBS) in identical manner as control. At 1 day-post inoculation (dpi), the innate immunity was strongly activated, and reacted rapidly to TMUV invasion, which was reflected as the significantly up-regulated IFN-stimulated genes (ISGs), especially in immune organs (e.g., thymus, bursa of Fabricius (BF) and spleen). Subsequently, under the continuous monitoring, the levels of IgA, IgM and IgG acting as the representative immunoglobulins (Igs) were constantly higher than those of mock ducklings, demonstrating that humoral immunity also played a major role in anti-virus infection. Despite the immune system activated positively, TMUV still caused systemic infection, and in particular, the immune organs were subject to severe damage in the early infection. With our constant observation, the injury of spleen and BF turned out to be getting more serious, and at 6 dpi, TMUV antigen was widely detected in both of two immune organs by immunohistochemistry (IHC) and main histopathological lesion presented as lymphocytopenia. Moreover, the elevated apoptosis rate of splenic lymphocytes and the alteration of immune organ index also revealed the damage of lymphoid organs and similarly, it is worth noting that severe damages were detected in thymus of TMUV-infected ducklings as well. In brief, the present study systematically described the dynamic damage of immune system after being attacked by TMUV and presented insights into the research of pathogenicity.

Abstract
Tripartite motif-containing 32 (TRIM32) is an E3 ubiquitin ligase with multiple functions. In this study, we amplified TRIM32 gene from the Cherry Valley duck, and its cDNA sequence contained an open reading frame of 1,950 bp that encodes 649 amino acids. Duck TRIM32 (duTRIM32) mRNA was expressed in all tissues tested. A series of immune-related genes that were induced by viral infection, including interferon alfa, IL-1β, retinoic acid–inducible gene-I, Mx, and OAS, were regulated by duTRIM32 expression. DuTRIM32 overexpression inhibits duck Tembusu virus (DTMUV) replication in the early stages of viral infection. Knockdown of duTRIM32 expression by siRNA reduced the ability of duck embryo fibroblast cells to mount a type Ⅰ interferon response to DTMUV. Therefore, our results suggest that the duTRIM32-mediated signal pathway plays an essential role in DTMUV infection-induced innate immune response.

Abstract
To better understand the pathogenicity of duck plague virus (DPV). The DPV Chinese standard challenge strain (DPV CSC) was continuously passaged 20 times in duck embryo fibroblasts (DEFs). DPV F1 was lethal for 2-week-ducks, but DPV F10 and F20 were not lethal for 2-week ducks, the 528 bp in UL2 region of DPV F1-F20 was deleted, which suggested that the deletion in UL2 region was not related with the virulence of DPV. Compared with DPV F20 infected ducks, IL-8 in DPV F1 infected ducks was significantly upregulated, but IL-1, IL-2,IFNγ and MHC-II were significantly downregulated. ISKNV copies in DPV F10 and F20 infected ducks were lower than the DPV F1 infected ducks. These results showed that massive viruses replication, upregulation of IL-8 expresssion, repression of IL-1, IL-2, IFNγ and MHC-II expression resulted in serious lesions and high mortality. This study provided a in-depth understanding of the immune-related genes expression in the different virulence of DPV.

Abstract
A novel goose astrovirus (GoAstV) outbreak in goslings, characterized by severe articular and visceral gout with high mortality, occurred in China. Although the pathogenesis of GoAstV-infected goslings has been explored in several studies, the host-immune response remains unclear. In this study, a goose astrovirus was isolated from goslings in Xiaogan, and designated as the HBXG strain. The full-length genome of HBXG was 7170 nt. A sequence analysis and phylogenetic trees revealed HBXG belonged to the novel GoAstV. We evaluated the viral distribution systematically and estimated immune related gene expression in HBXG-infected goslings. Results showed that GoAstV replicated quickly in many tissues and the highest titer was observed in the kidney, which reached 109.6 copies. TLR3, RIG-I and MDA5 were involved in the host-immune response to GoAstV, and the expression of IFN types I (IFN-α, IFN-β), inflammatory cytokines (IL-8, IL-10, TNF-α), antiviral proteins (Mx, OASL, PKR) and MHC-I were also upregulated during the infection. In contrast, the expression of proinflammatory cytokines (IL-1β, IL-6) and MHC-II were inhibited at 3 dpi. This study suggests that GoAstV is highly pathogenic to goslings, causing multiple systemic infections in tissues and the host-immune response is activated early in infection. However, rapid viral replication, suppression of inflammatory cytokines (IL-1β, IL-6) and MHC-II expressions were the possible reasons why the host-immune response cannot provide enough protection against GoAstV infection. This study is the first report to illuminate the immune response in goslings infected with GoAstV and offers insight into the pathogenesis of GoAstV.

Abstract
The duck Tembusu virus (DTMUV) is a novel mosquito-borne Flavivirus which caused huge economic losses for poultry industries in Southeast Asia and China. Currently, no effective antiviral drugs against this virus have been reported. (-)-Epigallocatechin-3-gallate (EGCG), a polyphenol present in abundance in green tea, has recently been demonstrated to have an antiviral activity for many viruses; however, whether EGCG can inhibit DTMUV infection remains unknown. Here, we tried to explore the anti-DTMUV effects and mechanisms of EGCG both in vitro and in vivo. Several EGCG treatment regimens were used to study the comprehensive antiviral activity of EGCG in DTMUV-infected baby hamster kidney cell line (BHK-21). The DTMUV titers of mock- and EGCG-treated infected cell cultures were determined using the tissue culture infective dose assay and the DTMUV mRNA copy number as determined using quantitative Real Time PCR. Moreover, the therapeutic efficacy of EGCG against DTMUV was assessed in DTMUV-infected ducklings. Our results suggested that EGCG significantly reduced the viral infection in BHK-21 cells in a dose-dependent manner, as reflected by the reduction of virus titers, virus copy number, and the expressions of viral E protein. We also observed that EGCG exhibited direct virucidal abilities against DTMUV. Notably, a significant reduction in virus binding ability was also observed, indicating that EGCG possesses excellent inhibitory effects on the viral adsorption step. In addition, DTMUV replication was also suppressed in BHK-21 cells treated with EGCG after viral entry, likely because of upregulation of the levels of interferon alfa and interferon beta. Finally, we also proved that EGCG exhibited anti-DTMUV efficacy in a duckling infection model because the survival rate was significantly improved. This is the first study to demonstrate the protective effect of EGCG against DTMUV, suggesting its potential use as an antiviral drug for DTMUV infection.

Abstract
Several phylogenetic clusters of duck Tembusu virus (DTMUV) that caused outbreaks in ducks in Asia have been identified since its emergence in 2010, highlighting the need for an efficient host system that can support isolation of all circulating phylogenetic clusters of DTMUV. In this study, various host systems, including different avian embryonated eggs (duck and chicken) and cell cultures (primary duck embryo fibroblast (DEF), primary chicken embryo fibroblast (CEF), baby hamster kidney (BHK-21), African green monkey kidney (Vero) and Aedes albopictus clone C6/36 (C6/36) cells), were evaluated and compared for their ability to support DTMUV isolation and propagation. Our results showed that all host systems were susceptible to DTMUV infection; however, BHK-21 and primary DEF cells supported more efficient replication of DTMUV compared to the other host systems.

Abstract
High-mobility group box 2 (HMGB2) belongs to the HMG-box family that participates in a variety of biologic processes. Recent studies have suggested that HMGB2 plays an important role in the innate immunity of fish. Cherry Valley duck is the main duck bred for meat consumption in China, but there is limited research available on the impact of duck HMGB2 (duHMGB2) in antiviral innate immunity. Here, duHMGB2 genes were first cloned and analyzed from the spleen of Cherry Valley ducks. We show that duHMGB2 is widely distributed in most tissues of healthy ducks, and duHMGB2 was differentially expressed in three organs (the spleen, brain, and lung) of ducks during different viral infections. duHMGB2 is mainly expressed in the nucleus of duck embryo fibroblast (DEF) cells. However, duHMGB2 is released into the cytoplasm after viral infection. DuHMGB2 induced expression of several genes that regulate the immune response. Moreover, duHMGB2 activated and upregulatede transcription factor NF-κB promoter activity. We also used single gene manipulations (knockout or overexpression) to confirm that duHMGB2 can inhibit the replication of duck plague virus, duck Tembusu virus, and the novel duck reovirus in DEF cells. These data show that duHMGB2 can activate the antiviral innate immunity of the host. Thus, duHMGB2 may be considered an immune adjuvant against infectious diseases in duck.

Abstract
Duck Tembusu virus (DTMUV) is an emerging pathogenic flavivirus that has caused enormous economic losses in Southeast Asia. However, the pathogenic mechanism and host's responses after DTMUV infection remain poorly understood. During this study, total mRNA sequencing (RNA-Seq) analysis was used to detect the global gene expression in DEFs at various time points after DTMUV infection. We identified 326 genes altered significantly at all time points, and these genes were dynamically enriched in multifarious biological processes, including apoptosis, innate immune response, DNA replication, cell cycle arrest and DNA repair. Next, the results showed that apoptosis was induced and the proportion of apoptosis increased with time, and pro-apoptotic molecules caspases were activated. The RNA-seq data analysis further revealed that most pro-apoptosis and anti-apoptosis genes were early continually responsive, and the genes involved in both intrinsic and extrinsic apoptotic pathways were initiated. Further, the considerably enriched immune-relevant pathways were involved in apoptosis process, and protein-protein interactions (PPIs) analysis showed that IL6, STAT1, TNFAIP3, CFLAR and PTGS2 may be key regulators of DEFs apoptosis. In conclusion, this study not only contributes to understanding the underlying mechanism of DEFs infection with DTMUV, but also provides new insights into targets screening for antiviral therapy.

Abstract
The disease caused by duck Tembusu virus (DTMUV) is characterized by severe egg-drop in laying ducks. Currently, the disease has spread to most duck-raising areas in China, leading to great economic losses in the duck industry. In the recent years, DTMUV has raised some concerns, because of its expanding host range and increasing pathogenicity, as well as the potential threat to public health. Innate immunity is crucial for defending against invading pathogens in the early stages of infection. Recently, studies on the interaction between DTMUV and host innate immune response have made great progress. In the review, we provide an overview of DTMUV and summarize current advances in our understanding of the interaction between DTMUV and innate immunity, including the host innate immune responses to DTMUV infection through pattern recognition receptors (PRRs), signaling transducer molecules, interferon-stimulated genes (ISGs), and the immune evasion strategies employed by DTMUV. The aim of the review is to gain an in-depth understanding of DTMUV pathogenesis to facilitate future studies.

Abstract
Chicken type I interferons (type I IFNs) are key antiviral players of the chicken innate immune system and are considered potent antiviral agents against avian viral pathogens. Chicken type I IFNs are divided into three subtypes namely, chIFN-α, chIFN-β, and chIFN-κ. Viral pathogen-associated molecular patterns (PAMPs) recognized by their corresponding specific PRRs (pattern recognition receptors) induce the expression of chicken type I IFNs. Interaction of chicken type I IFNs with their subsequent IFN receptors results in the activation of the JAK-STAT pathway, which in turn activates hundreds of chicken interferon-stimulated genes (chISGs). These chISGs establish an antiviral state in neighboring cells and prevent the replication and dissemination of viruses within chicken cells. Chicken type I IFNs activate different pathways that constitute major antiviral innate defense mechanisms in chickens. However, evolutionary mechanisms in viruses have made them resistant to these antiviral players by manipulating host innate immune pathways. This review focuses on the underlying molecular mechanisms employed by avian RNA viruses to counteract chicken type I IFNs and chISGs through different viral proteins. This may help to understand host-pathogen interactions and the development of novel therapeutic strategies to control viral infections in poultry.

Abstract
Mammalian interferon-induced protein with tetratricopeptide repeats family proteins (IFITs) play important roles in host innate immune response to viruses. Recently, studies have shown that IFIT from poultry also plays a crucial part in antiviral function. This study first reports the regulation of duck Tembusu virus (DTMUV) replication by IFIT5 and the effect of duck IFIT5 (duIFIT5) on the innate immune response after DTMUV infection. Firstly, duIFIT5 was obviously increased in duck embryo fibroblast cells (DEFs) infected with DTMUV. Compared to the negative control, we found that in the duIFIT5-overexpressing group, the DTMUV titer at 24 h post infection (hpi) was significantly reduced, but the viral titer was strikingly increased at 48 hpi. Moreover, overexpression of duIFIT5 could significantly inhibit IFN-β transcription and IFN-β promoter activation at indicated time points after DTMUV infection. Further, in DTMUV-infected or poly(I:C)-stimulated DEFs, overexpression of duIFIT5 also significantly inhibited the activation of NF-κB and IRF7 promoters, as well as the activation of downstream IFN induced the interferon-stimulated response element (ISRE) promoter. Meanwhile, the transcription level of antiviral protein Mx, but not OASL, was obviously decreased at various time points. The opposite results were obtained by knockdown of duIFIT5 in DTMUV-infected or poly(I:C)-stimulated DEFs. Compared to the negative control, knockdown of duIFIT5 promoted DTMUV titer and DTMUV envelope (E) protein expression at 24 hpi, but DTMUV titer and E protein expression was markedly decreased at 48 hpi. Additionally, the promoters of IFN-β, NF-κB, IRF7 and ISRE were significantly activated in the duIFIT5 knockdown group. Collectively, duIFIT5 differentially regulates DTMUV replication and inhibits virus-triggered innate immune response.

Abstract
ATP-dependent DEAD (Asp-Glu-Ala-Asp)-box RNA helicases not only regulate RNA metabolism, but also are involved in host antiviral innate immune responses. It is important to investigate the orthologs of this protein family to broaden our understanding of innate immunity and promote protective strategies against viral infections in ducks. In the current study, duck DDX3X (duDDX3X) was first cloned, which consists of 1959 bp encoding a protein of 652 amino acids. duDDX3X has the typical structure of this family, including nine motifs, DEAD and HELICc domains. The amino acid sequence of duDDX3X shares a high similarity with the DDX3Xs of avian and mammalian. Quantitative real-time PCR indicated that duDDX3X was ubiquitously expressed in nearly all tissues. Overexpression of duDDX3X could activate interferon (IFN)-β and enhance the RIG-I-induced IFN-β yield in duck embryo fibroblast cells. However, duDDX3X had no significant effect on the expression of proinflammatory cytokines such as IL-1β, IL-6, and CXCL-8. Tembusu virus (TMUV) infection significantly downregulated duDDX3X. Overexpression and siRNA interference studies showed that duDDX3X inhibited the replication of TMUV through IFN-β at the early stages of infection. Collectively, our results indicated that duDDX3X could positively modulate type I interferon and play an essential role in response to TMUV infection. This study will contribute to a better understanding of duDDX3X in the innate immune system of ducks and lay a solid foundation for further studies of duDDX3X in antiviral immunity.

Binding of Duck Tembusu Virus Nonstructural Protein 2A to Duck STING Disrupts Induction of Its Signal Transduction Cascade To Inhibit Beta Interferon Induction. J Virol 2020; 94:JVI.01850-19. [PMID: 32075929 DOI: 10.1128/jvi.01850-19] [Citation(s) in RCA: 24] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2019] [Accepted: 02/09/2020] [Indexed: 12/28/2022] Open
Abstract
Duck Tembusu virus (DTMUV), which is similar to other mosquito-borne flaviviruses that replicate well in most mammalian cells, is an emerging pathogenic flavivirus that has caused epidemics in egg-laying and breeding waterfowl. Immune organ defects and neurological dysfunction are the main clinical symptoms of DTMUV infection. Preinfection with DTMUV makes the virus impervious to later interferon (IFN) treatment, revealing that DTMUV has evolved some strategies to defend against host IFN-dependent antiviral responses. Immune inhibition was further confirmed by screening for DTMUV-encoded proteins, which suggested that NS2A significantly inhibited IFN-β and IFN-stimulated response element (ISRE) promoter activity in a dose-dependent manner and facilitated reinfection with duck plague virus (DPV). DTMUV NS2A was able to inhibit duck retinoic acid-inducible gene-I (RIG-I)-, and melanoma differentiation-associated gene 5 (MDA5)-, mitochondrial-localized adaptor molecules (MAVS)-, stimulator of interferon genes (STING)-, and TANK-binding kinase 1 (TBK1)-induced IFN-β transcription, but not duck TBK1- and interferon regulatory factor 7 (IRF7)-mediated effective phases of IFN response. Furthermore, we found that NS2A competed with duTBK1 in binding to duck STING (duSTING), impaired duSTING-duSTING binding, and reduced duTBK1 phosphorylation, leading to the subsequent inhibition of IFN production. Importantly, we first identified that the W164A, Y167A, and S361A mutations in duSTING significantly impaired the NS2A-duSTING interaction, which is important for NS2A-induced IFN-β inhibition. Hence, our data demonstrated that DTMUV NS2A disrupts duSTING-dependent antiviral cellular defenses by binding with duSTING, which provides a novel mechanism by which DTMUV subverts host innate immune responses. The potential interaction sites between NS2A and duSTING may be the targets of future novel antiviral therapies and vaccine development.IMPORTANCE Flavivirus infections are transmitted through mosquitos or ticks and lead to significant morbidity and mortality worldwide with a spectrum of manifestations. Infection with an emerging flavivirus, DTMUV, manifests with clinical symptoms that include lesions of the immune organs and neurological dysfunction, leading to heavy egg drop and causing serious harm to the duck industry in China, Thailand, Malaysia, and other Southeast Asian countries. Mosquito cells, bird cells, and mammalian cell lines are all susceptible to DTMUV infection. An in vivo study revealed that BALB/c mice and Kunming mice were susceptible to DTMUV after intracerebral inoculation. Moreover, there are no reports about DTMUV-related human disease, but antibodies against DTMUV and viral RNA were detected in serum samples of duck industry workers. This information implies that DTMUV has expanded its host range and may pose a threat to mammalian health. However, the pathogenesis of DTMUV is largely unclear. Our results show that NS2A strongly blocks the STING-induced signal transduction cascade by binding with STING, which subsequently blocks STING-STING binding and TBK1 phosphorylation. More importantly, the W164, Y167, or S361 residues in duSTING were identified as important interaction sites between STING and NS2A that are vital for NS2A-induced IFN production and effective phases of IFN response. Uncovering the mechanism by which DTMUV NS2A inhibits IFN in the cells of its natural hosts, ducks, will help us understand the role of NS2A in DTMUV pathogenicity.

Abstract
Duck tembusu virus (DTMUV) is newly emerged in poultry and causes great losses to the breeding industry in China and neighboring countries. Effective antiviral strategies are still being studied. Autophagy is a cellular degradative pathway, and our lab's previous data show that autophagy promotes DTMUV replication in vitro. To study the role of autophagy further in vivo, we utilized ducks as the animal model to investigate the autophagy responses in DTMUV-targeted tissues. And also, we utilized autophagy regulators, including Rapamycin (Rapa) as the autophagy enhancer, 3-Methyladenine (3-MA) and Chloroquine (CQ) as the autophagy inhibitors, to adjust the host autophagic levels and then study the effects of autophagy on tissue damages and virus replication. As a result, we first found DTMUV infection trigged autophagy and autophagy regulator treatments regulated autophagy levels successfully in duck spleens and brains. Next, we found that autophagy inhibitors inhibited DTMUV replication and alleviated DTMUV-induced pathological symptoms, whereas the autophagy inducer treatment led to the opposite effects. And we also found that autophagic regulation was correlated with the expression of innate immune genes, including pattern recognition receptors, type I interferons, and cytokines, and caused different effects in different tissues. In summary, we demonstrated that autophagy facilitated DTMUV replication, aggravated the developments of pathological symptoms and possibly counteracts the host's innate immunity response in vivo.

Abstract
The duck Tembusu virus (DTMUV) is a mosquito-borne flavivirus. It causes severe symptoms of egg-drop, as well as neurological symptoms and brain damage in ducks. However, the specific molecular mechanisms of DTMUV-induced neurovirulence and host responses in the brain remain obscure. To better understand the host-pathogen and neuro-immune interactions of DTMUV infection, we conducted high-throughput RNA-sequencing to reveal the transcriptome profiles of DTMUV-infected duck brain. Totals of 117, 212, and 150 differentially expressed genes (DEGs) were identified at 12, 24, and 48 h post infection (hpi). Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses uncovered genes and pathways related to the nervous system and immune responses in duck brain. Neuro-related genes, including WNT3A, GATA3, and CHRNA6, were found to be significantly downregulated. RIG-I-like receptors (DHX58, IFIH1) and Toll-like receptors (TLR2 and TLR3) were activated, inducing the expression of 22 interferon stimulated genes (ISGs) and antigen-processing and -presenting genes (TAP1 and TAP2) in the brain. Our research provides comprehensive information for the molecular mechanisms of neuro-immune and host-pathogen interactions of DTMUV.

Basic Amino Acid Substitution at Residue 367 of the Envelope Protein of Tembusu Virus Plays a Critical Role in Pathogenesis. J Virol 2020; 94:JVI.02011-19. [PMID: 32024774 DOI: 10.1128/jvi.02011-19] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2019] [Accepted: 01/24/2020] [Indexed: 02/07/2023] Open
Abstract
Tembusu virus (TMUV) is a flavivirus responsible for panzootic outbreaks of severe egg-drop and fatal encephalitis of domestic waterfowl in China. Although TMUV can be attenuated by in vitro passaging, experimental evidence supporting the role of specific genetic changes in virulence attenuation is currently lacking. Here, we performed site-directed mutagenesis on five envelope (E) protein amino acid residues in accordance with the attenuated TMUV generated in our recent study. Our results showed that the Thr-to-Lys mutation of residue 367 in E protein (E367) plays a predominant role in viral cell adaptation and virulence attenuation in ducks compared with mutations in other residues. We further demonstrated that the positively charged basic amino acid substitution at E367 enhanced the viral binding affinity for glycosaminoglycans (GAGs) and reduced viremia levels and the efficiency of replication in major target organs in subcutaneously inoculated ducks. Interestingly, the T367K mutation increased viral neutralization sensitivity to the early immune sera. Together, our findings provide the first evidence that a basic amino acid substitution at E367 strongly impacts the in vitro and in vivo infection of TMUV.IMPORTANCE Outbreaks of Tembusu virus (TMUV) infection have caused huge economic losses in the production of domestic waterfowl since the virus was first recognized in China in 2010. To control TMUV infection, a live-attenuated vaccine candidate of TMUV was developed in our previous study, but the mechanisms of virulence attenuation are not fully understood. Here, we found that the Thr-to-Lys substitution at E367 is a crucial determinant of TMUV virulence attenuation in ducks. We demonstrated that the T367K mutation attenuates TMUV through reducing viral replication in the blood, brain, heart (ducklings), and ovaries. These data provide new insights into understanding the pathogenesis of TMUV and the rational development of novel TMUV vaccines.

Abstract
High-mobility group box 1 protein (HMGB1) shows endogenous damage-associated molecular patterns (DAMPs) and is also an early warning protein that activates the body's innate immune system. Here, the full-length coding sequence of HMGB1 was cloned from the spleen of Cherry Valley duck and analyzed. We find that duck HMGB1(duHMGB1) is mostly located in the nucleus of duck embryo fibroblast (DEF) cells under normal conditions but released into the cytoplasm after lipopolysaccharide (LPS) stimulation. Knocking-down or overexpressing duHMGB1 had no effect on the baseline apoptosis rate of DEF cells. However, overexpression increased weakly apoptosis after LPS activation. In addition, overexpression strongly activated the IFN-I/IRF7 signaling pathway in DEF cells and significantly increased the transcriptional level of numerous pattern recognition receptors (PRRs), pro-inflammatory cytokines (IL-6, TNF-α), IFNs and antiviral molecules (OAS, PKR, Mx) starting from 48 h post-transfection. Overexpression of duHMGB1 strongly impacted duck virus replication, either by inhibiting it from the first stage of infection for novel duck reovirus (NDRV) and at late stage for duck Tembusu virus (DTMUV) or duck plague virus (DPV), or promoting replication at early stage for DTMUV and DPV infection. Importantly, data from duHMGB1 overexpression and knockdown experiments, time-dependent DEF cells transcriptional immune responses suggest that duHMGB1 and RIG-I receptor might cooperate to promote the expression of antiviral proteins after NDRV infection, as a potential mechanism of duHMGB1-mediated antiviral activity.

Abstract
Duck tembusu virus (DTMUV) is a single-stranded, positive-polarity RNA flavivirus that has caused considerable economic losses in China in recent years. Innate immunity represents the first line of defense against invading pathogens and serves as an important role in resisting viral infections. In this study, we found that the infection of ducks by DTMUV triggers Toll-like receptors (TLRs) and (RIG-I)-like receptors (RLRs) signaling pathways and inducing abundant of pro-inflammatory factors and type I interferons (IFNs), in which melanoma differentiation-associated gene 5 (MDA5) and Toll-like receptor 3 (TLR3) play important immunity roles, they can inhibit the replication process of DTMUV via inducing type I IFNs. Moreover, we demonstrated that type I IFNs can inhibit the DTMUV replication process in a time- and dose-dependent manner. Exosomes are small membrane vesicles that have important roles in intercellular communication. MicroRNAs (miRNAs) are small non-coding RNAs that can modulate gene expression and are common substances in exosomes. In our experiment, we successfully isolated DEF cells derived exosome for the first time and explored its function. Firstly, we found the expression of miR-148a-5p is significantly decreased following DTMUV infect. Then we found miR-148a-5p can target TLR3 and down-regulate the expression of TLR3, serving as a negative factor in innate immunity. Unfortunately, we cannot find miRNAs with different expression changes that can target MDA5. Lastly, our experimental results showed that TLR3 was one of the causes of miR-148a-5p reduction, suggesting that the high level of TLR3 after DTMUV infect can both trigger innate immunity and suppress miR-148a-5p to resist DTMUV.

Duckling short beak and dwarfism syndrome virus infection activates host innate immune response involving both DNA and RNA sensors. Microb Pathog 2019; 138:103816. [PMID: 31655218 DOI: 10.1016/j.micpath.2019.103816] [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: 09/16/2019] [Revised: 10/21/2019] [Accepted: 10/21/2019] [Indexed: 11/27/2022]
Abstract
Duckling short beak and dwarfism syndrome virus (SBDSV), a newly identified goose parvovirus, causes devastating disease in domestic waterfowl and considerable economic losses to Chinese waterfowl industry. The molecular pathogenesis of SBDSV infection, nature and dynamics of host immune responses against SBDSV infection remained elusive. In this study, we systematically explored the relative mRNA expression profiles of major innate immune-related genes in SBDSV infected duck embryo fibroblasts. We found that SBDSV infection effectively activated host innate immune responses and resulted in significant up-regulation of IFN-β and several vital IFN-stimulated genes (ISGs). These up-regulation responses were mainly attributed to viral genomic DNA and dsRNA replication intermediates. Importantly, the expression of cGAS was significantly induced, whereas the expression of other DNA receptors including DDX41, STING, ZBP1, LSM14A and LRRFIP1 have no significant change. Furthermore, SBDSV infection also activates the up-regulation of TLR3 and inhibited the expression of TLR2 and TLR4; however, no effect was observed on the expression of TLR1, TLR5, TLR7, TLR15 and TLR21. Intriguingly, SBDSV infection significantly up-regulated the expression of RNA sensors such as MDA5 and LGP2, and resulted in a delayed but significant up-regulation of RIG-I gene. Taken together, these data indicate that host multiple sensors including DNA sensor (cGAS) and RNA sensors (TLR3, MDA5 and LGP2) are involved in recognizing a variety of different pathogen associated molecular patterns (PAMPs) including viral genomic ssDNA and dsRNA replication intermediates, which trigger an effective antiviral innate immune response.

[PMID: 31387589 PMCID: PMC6685157 DOI: 10.1186/s12917-019-2020-8] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2019] [Accepted: 07/25/2019] [Indexed: 01/03/2023] Open
Abstract
Background Although several studies have revealed that the sensitivity of ducklings to duck Tembusu virus (DTMUV) was related to age, however, DTMUV was originally isolated from egg-laying ducks, and the ovary was the target organ of this virus. Cherry Valley breeding ducks aged 15- and 55-week-old (they are reserve breeding ducks and the normal egg-laying breeding ducks, respectively) were infected with DTMUV, using intramuscular injection, to study the effect of age-related difference on the pathogenicity of DTMUV in breeding ducks. Results Examinations of clinical symptoms, gross and microscopic lesions, viral loads, cytokines and serum neutralizing antibodies were performed. Results showed that obvious clinical symptoms, such as depression, ruffled feathers, ataxia and egg-laying drop were observed in the 55-week-old laying ducks, with five ducks dying at 5–7 days post infection (dpi). The 15-week-old ducks showed slight symptoms during infection. Gross lesions were severe and characterized by the congestion, hemorrhage and swelling of some organs in the 55-week-old ducks, including the hemorrhage of endocardium, hepatomegaly, splenomegaly, oviduct hemorrhage, hyperemia and deformation of the ovary. Mild endocardial hemorrhage and hepatosplenomegaly were observed in the 15-week-old ducks. Similarly, there was a significant difference in microscopic lesions between the two groups. The older ducks displayed severe microscopic lesions, specifically in the hemorrhage, interstitial inflammatory cell infiltration of the endocardium, typical viral encephalitis and hemorrhage in the ovary. But on the whole, the 15-week-old ducks showed milder lesions. Viral loads in tissues of the older group were significantly higher than those of the younger group. The levels of interferon (IFN)-γ, interleukin (IL)-2 and neutralizing antibody in the 15-week-old ducks were higher than in the 55-week-old ducks at the early stage of the DTMUV infection, suggesting the immune response in the younger ducks to DTMUV was stronger than in the older ducks. Conclusions These results demonstrated that age-related differences in susceptibility to DTMUV in breeding ducks was significant, with 55-week-old egg-laying ducks being more susceptible to DTMUV than 15-week-old reserve breeding ducks.

Abstract
Egg drop syndrome virus (EDSV), a member of the family Adenoviridae and an economically important pathogen with a broad host range, leads to markedly decreased egg production. However, the molecular mechanism underlying the host-EDSV interaction remains unclear. Here, we performed high-throughput RNA sequencing (RNA-Seq) to study the dynamic changes in host gene expression at 6, 12, and 24 hours post-infection in duck embryo fibroblasts (DEFs) infected with EDSV. Atotal of 441 differentially expressed genes (DEGs) were identified after EDSV infection. Gene Ontology category and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis revealed that these DEGs were associated with multiple biological functions, including signal transduction, host immunity, virus infection, cell apoptosis, cell proliferation, and pathogenicity-related and metabolic process signaling pathways. We screened and identified 12 DEGs for further examination by using qRT-PCR. The qRT-PCR and RNA-Seq results were highly consistent. This study analyzed viral infection and host immunity induced by EDSV infection from a novel perspective, and the results provide valuable information regarding the mechanisms underlying host-EDSV interactions, which will prove useful for the future development of antiviral drugs or vaccines for poultry, thus benefiting the entire poultry industry.

Abstract
Outbreaks of duck Tembusu virus (DTMUV) have caused substantial economic losses in the major duck-producing regions of China since 2010. To improve our understanding of the host cellular responses to virus infection and the pathogenesis of DTMUV infection, we applied isobaric tags for relative and absolute quantification (iTRAQ) labeling coupled with multidimensional liquid chromatography-tandem mass spectrometry to detect the protein changes in duck embryo fibroblast cells (DEFs) infected and mock-infected with DTMUV. In total, 434 cellular proteins were differentially expressed, among which 116, 76, and 339 proteins were differentially expressed in the DTMUV-infected DEFs at 12, 24, and 42 hours postinfection, respectively. The Gene Ontology analysis indicated that the biological processes of the differentially expressed proteins were primarily related to cellular processes, metabolic processes, biological regulation, response to stimulus, and cellular organismal processes and that the molecular functions in which the differentially expressed proteins were mainly involved were binding and catalytic activity. Some selected proteins that were found to be differentially expressed in DTMUV-infected DEFs were further confirmed by real-time PCR. The results of this study provide valuable insight into DTMUV-host interactions. This could lead to a better understanding of DTMUV infection mechanisms.

Abstract
Duck Tembusu virus (DTMUV) is a novel member of flavivirus with the highest viral loads in the spleen. Six-month egg-laying shelducks were intramuscularly injected with DTMUV strain XZ-2012. Morphological analysis revealed the presence of vacuolar degeneration in the periellipsoidal lymphatic sheaths (PELS) of spleen white pulp following infection, especially from 12 hpi to 3 dpi. Ultrastructural images showed an obvious swelling of cells and their mitochondria and endoplasmic reticulum. Using RNA-seq analysis, the expression levels of RIG-I like receptors (RLRs), downstream IRF7 and proinflammatory cytokines IL-6 from RIG-I signaling pathway were non-apparently upregulated at 2 hpi and apparently at 3 dpi, while MHC-II expression was obviously downregulated at 2 hpi. The expression levels of downstream antiviral cytokines type-I IFNs, anti-inflammatory cytokines IL-10, cell adhesion molecules (CAMs), chemokines and their receptors associated with lymphocyte homing were significantly upregulated at 3 dpi. The population of lymphocyte was increased at 6 dpi. The immune function of spleen was recovered starting from 9 dpi. These findings of this study suggest that DTMUV invaded into the spleen via RIG-I signaling pathway and enhanced immune evasion by inhibiting MHC-II expression during the early stage of infection. Additionally, DTMUV induced PELS lesions through activating IL-6 expression. Furthermore, DTMUV increased the expression levels of RLRs, antiviral type-I IFNs, lymphocyte homing-related genes and proteins as well as the number of lymphocytes in the infected duck spleen. Taken altogether, this study provides new insights into the cellular and molecular mechanisms of DTMUV infection in duck spleen.

Abstract
Major histocompatibility complex class I (MHC I) molecules are critically involved in defense against pathogens, and their high polymorphism is advantageous to a range of immune responses, especially in duck displaying biased expression of one MHC I gene. Here, we examined MHC I polymorphism in two duck (Anas platyrhynchos) breeds from China: Shaoxing (SX) and Jinding (JD). Twenty-seven unique UAA alleles identified from the MHC I genes of these breeds were analyzed concerning amino acid composition, homology, and phylogenetic relationships. Based on amino acid sequence homology, allelic groups of Anas platyrhynchos MHC I (Anpl-MHC I) were established and their distribution was analyzed. Then, highly variable sites (HVSs) in peptide-binding domains (PBD) were estimated and located in the three-dimensional structure of Anpl-MHC I. The UAA alleles identified showed high polymorphism, based on full-length sequence homology. By adding the alleles found here to known Anpl-MHC I genes from domestic ducks, they could be divided into 17 groups and four novel groups were revealed for SX and JD ducks. The UAA alleles of the two breeds were not divergent from the MHC I of other duck breeds, and HVSs were mostly located in the peptide-binding groove (PBG), suggesting that they might determine peptide-binding characteristics and subsequently influence peptide presentation and recognition. The results from the present study enrich Anpl-MHC I polymorphism data and clarify the distribution of alleles with different peptide-binding specificities, which might also accelerate effective vaccine development and help control various infections in ducks.

Abstract
Duck is a major waterfowl species in China, providing high-economic benefit with a population of up to 20–30 billion per year. Ducks are commonly affected by severe diseases, including egg-drop syndrome caused by duck Tembusu virus (DTMUV). The immune mechanisms against DTMUV invasion and infection remain poorly understood. In this study, duck embryo fibroblasts (DEFs) were infected with DTMUV and harvested at 12 and 24 h post-infection (hpi), and their genomes were sequenced. In total, 911 (764 upregulated and 147 downregulated genes) and 3008 (1791 upregulated and 1217 downregulated) differentially expressed genes (DEGs) were identified at 12 and 24 hpi, respectively. Kyoto Encyclopedia of Genes and Genomes enrichment analysis revealed that DEGs were considerably enriched in immune-relevant pathways, including Toll-like receptor signaling pathway, Cytosolic DNA-sensing pathway, RIG-I-like receptor signaling pathway, Chemokine signaling pathway, NOD-like receptor signaling pathway, and Hematopoietic cell lineage at both time points. The key DEGs in immune system included those of the cytokines (IFN α2, IL-6, IL-8L, IL-12B, CCR7, CCL19, and CCL20), transcription factors or signaling molecules (IRF7, NF-κB, STAT1, TMEM173, and TNFAIP3), pattern recognition receptors (RIG-I and MDA5), and antigen-presenting proteins (CD44 and CD70). This suggests DTMUV infection induces strong proinflammatory/antiviral effects with enormous production of cytokines. However, these cytokines could not protect DEFs against viral attack. Our data revealed valuable transcriptional information regarding DTMUV-infected DEFs, thereby broadening our understanding of the immune response against DTMUV infection; this information might contribute in developing strategies for controlling the prevalence of DTMUV infection.

Abstract
Recently, a newly emerged avian flavivirus, duck Tembusu virus (TMUV), was identified as the causative agent of a serious duck viral disease in Asia. Its rapid spread and expanded host range have raised substantial concerns regarding its potential threat to non-avian hosts, including humans. In this study, we report an infectious cDNA clone for a clinical strain CQW1 isolated from Southwest China, which is representative of the disease outbreak in the Chinese mainland. We generated a full-length cDNA clone pACYC FL-TMUV, which is infectious, and this cDNA clone-derived recombinant TMUV (rTMUV) showed comparative growth kinetics in both BHK21 cells and DEF cells compared with parental TMUV (pTMUV). In addition, rTMUV also showed the same high virulence in 9-day-old duck embryos as that in pTMUV, suggesting that rTMUV possessed similar properties to the natural virus both in vitro and in vivo. Based on the cDNA-clone, we first generated a reporter TMUV (TMUV-RLuc) carrying a Renilla luciferase (RLuc) gene. The luciferase kinetics of TMUV-RLuc were determined both in BHK21 and DEF cells. It seems that TMUV-RLuc grew well in vitro; however, the insertion of the RLuc gene attenuated viral replication in vitro. The higher viral titres of TMUV-RLuc were observed in BHK21 compared with that in DEF cells. The antiviral effects of exogenous-expressed duck RIG-I, MDA5, STING, MAVS, TBK1, IFNα and IFNγ were studied in vitro by using TMUV-RLuc. Our reverse genetics system will provide a multicomponent platform for the pathogenesis study of duck TMUV and the development of molecular countermeasures against duck TMUV infection.

Comparative liver transcriptome analysis in ducklings infected with duck hepatitis A virus 3 (DHAV-3) at 12 and 48 hours post-infection through RNA-seq. Vet Res 2018; 49:52. [PMID: 29925406 PMCID: PMC6011267 DOI: 10.1186/s13567-018-0545-7] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2017] [Accepted: 02/23/2018] [Indexed: 01/18/2023] Open
Abstract
Duck hepatitis A virus 3 (DHAV-3), the only member of the novel genus Avihepatovirus, in the family Picornaviridae, can cause significant economic losses for duck farms in China. Reports on the pathogenicity and the antiviral molecular mechanisms of the lethal DHAV-3 strain in ducklings are inadequate and remain poorly understood. We conducted global gene expression profiling and screened differentially expressed genes (DEG) of duckling liver tissues infected with lethal DHAV-3. There were 1643 DEG and 8979 DEG when compared with mock ducklings at 12 hours post-infection (hpi) and at 48 hpi, respectively. Gene pathway analysis of DEG highlighted mainly biological processes involved in metabolic pathways, host immune responses, and viral invasion. The results may provide valuable information for us to explore the pathogenicity of the virulent DHAV-3 strain and to improve our understanding of host–virus interactions.

Analysis of the microRNA expression profiles in DEF cells infected with duck Tembusu virus. INFECTION GENETICS AND EVOLUTION 2018; 63:126-134. [PMID: 29803008 DOI: 10.1016/j.meegid.2018.05.020] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/02/2018] [Revised: 05/13/2018] [Accepted: 05/22/2018] [Indexed: 02/06/2023]
Abstract
Duck Tembusu virus (DTMUV), belonging to the Flaviviridae family, is a single-stranded positive-sense RNA virus. Since April 2010, the outbreak of DTMUV in southeast provinces of China has caused great economic losses. MicroRNAs (miRNAs) play important regulatory roles in viral infection through binding to the host target genes or the viral genomes. To better understanding the molecular mechanisms of virus-host interaction, here we identified the miRNA expression profiles in DTMUV-infected and uninfected DEF cells by high-throughput sequencing. A total of 287 known and 63 novel miRNAs were identified. 48 miRNAs, including 26 known miRNAs and 22 novel miRNAs, were differentially expressed in response to DTMUV infection. Among these miRNAs, 37 miRNAs were up-regulated and 11 miRNAs were down-regulated. 9 miRNAs were randomly selected for validation by qRT-PCR experiment. The results of qRT-PCR experiment were consistent with the sequencing data. GO enrichment showed that the predicted targets of these differentially expressed miRNAs were mainly involved in the regulation of immune system, cellular process and metabolic process. KEGG pathways analysis showed that predicted target genes were involved in several signaling pathways such as Wnt signaling pathway, TGF-beta signaling pathway, mTOR signaling pathway and FoxO signaling pathway. This is the first study to evaluate changes of miRNA expression in DEF cells upon DTMUV infection. Our findings provide important clues for better understanding the DTMUV-host interaction.

Abstract
Flaviviridae family is a class of single-stranded RNA virus, which is fatal to human and animals and mainly prevalent in subtropic and tropic countries. Even though people and animals are barraged with flavivirus infection every year, we have not invented either vaccines or antiviral for most flavivirus infections yet. Innate immunity is the first line of defense in resisting pathogen invasion, serving an important role in a resisting virus. Toll-like receptors (TLRs) and retinoic acid-inducible gene I- (RIG-I-) like receptors (RLRs) are crucial pattern recognition receptors (PRRs) that play essential roles in recognizing and clearing pathogens, including resisting flavivirus. In the present review, we provide a significant reference for further research on the function of innate immunity in resisting flavivirus.

Abstract
The emergence of duck tembusu virus (DTMUV), a new member of the Flavivirus genus, has caused great economical loss in the poultry industry in China. Since the outbreak and spread of DTMUV is hard to control in a clinical setting, an efficient and low-cost oral delivery DNA vaccine SL7207 (pVAX1-C) based on the capsid protein of DTMUV was developed and evaluated in this study. The antigen capsid protein was expressed from the DNA vaccine SL7207 (pVAX1-C), both in vitro and in vivo. The humoral and cellular immune responses in vivo were observed after oral immunization with the SL7207 (pVAX1-C) DNA vaccine. High titers of the specific antibody against the capsid protein and the neutralizing antibody against the DTMUV virus were both detected after inoculation. The ducks were efficiently protected from lethal DTMUV exposure by the SL7207 (pVAX1-C) vaccine in this experiment. Taken together, we demonstrated that the capsid protein of DTMUV possesses a strong immunogenicity against the DTMUV infection. Moreover, an oral delivery of the DNA vaccine SL7207 (pVAX1-C) utilizing Salmonella SL7207 was an efficient way to protect the ducks against DTMUV infection and provides an economic and fast vaccine delivery strategy for a large scale clinical use.
