Abstract
Newcastle disease virus (NDV) typically induces severe illness in poultry and results in significant economic losses for the worldwide poultry sector. NDV, an RNA virus with a single-stranded negative-sense genome, is susceptible to mutation and immune evasion during viral transmission, thus imposing enormous challenges to avian health and poultry production. NDV is composed of six structural proteins and two nonstructural proteins that exert pivotal roles in viral infection and antiviral responses by interacting with host proteins. Nowadays, there is a particular focus on the mechanisms of virus-host protein interactions in NDV research, yet a comprehensive overview of such research is still lacking. Herein, we briefly summarize the mechanisms regarding the effects of virus-host protein interaction on viral infection, pathogenesis, and host immune responses. This review can not only enhance the present comprehension of the mechanism underlying NDV and host interplay, but also furnish a point of reference for the advancement of antiviral measures.

Abstract
Reactive oxygen species (ROS) accumulation inside the cells instigates oxidative stress, activating stress-responsive genes. The viral strategies for promoting stressful conditions and utilizing the induced host proteins to enhance their replication remain elusive. The present work investigates the impact of oxidative stress responses on Newcastle disease virus (NDV) pathogenesis. Here, we show that the progression of NDV infection varies with intracellular ROS levels. Additionally, the results demonstrate that NDV infection modulates the expression of oxidative stress-responsive genes, majorly sirtuin 7 (SIRT7), a NAD+-dependent deacetylase. The modulation of SIRT7 protein, both through overexpression and knockdown, significantly impacts the replication dynamics of NDV in DF-1 cells. The activation of SIRT7 is found to be associated with the positive regulation of cellular protein deacetylation. Lastly, the results suggested that NDV-driven SIRT7 alters NAD+ metabolism in vitro and in ovo. We concluded that the elevated expression of NDV-mediated SIRT7 protein with enhanced activity metabolizes the NAD+ to deacetylase the host proteins, thus contributing to high virus replication.

Abstract
IMPORTANCE Birds represent important hosts for numerous viruses, including zoonotic viruses and pathogens with the potential to cause major economic losses to the poultry industry. Viral replication and transmission can be inhibited or blocked by the action of antiviral restriction factors (RFs) encoded by the host. One well-characterized RF is tetherin, a protein that directly blocks the release of newly formed viral particles from infected cells. Here, we describe the evolutionary loss of a functional tetherin gene in two galliform birds, turkey (Meleagris gallopavo) and Mikado pheasant (Syrmaticus mikado). Moreover, we demonstrate that the structurally related protein TMCC(aT) exerts antiviral activity in several birds, albeit by a mechanism different from that of tetherin. The evolutionary scenario described here represents the first documented loss-of-tetherin cases in vertebrates.

Abstract
As an important structural protein in virion morphogenesis, the matrix (M) protein of Newcastle disease virus (NDV) is demonstrated to be a nuclear-cytoplasmic trafficking protein and plays essential roles in viral assembly and budding. In recent years, increasing lines of evidence have indicated that the M protein has obvious influence on the pathotypes of NDV, and the interaction of M protein with cellular proteins is also closely associated with the replication and pathogenicity of NDV. Although substantial progress has been made in the past 40 years towards understanding the structure and function of NDV M protein, the available information is scattered. Therefore, this review article summarizes and updates the research progress on the structural feature, virulence and pathotype correlation, and nucleocytoplasmic transport mechanism of NDV M protein, as well as the functions of M protein and cellular protein interactions in M's intracellular localization, viral RNA synthesis and transcription, viral protein synthesis, viral immune evasion, and viral budding and release, which will provide an in-depth understanding of the biological functions of M protein in the replication and pathogenesis of NDV, and also contribute to the development of effective antiviral strategies aiming at blocking the early or late steps of NDV lifecycles.

Abstract
The matrix (M) protein of Newcastle disease virus (NDV) contains large numbers of unevenly distributed basic residues, but the precise function of most basic residues in the M protein remains enigmatic. We previously demonstrated that the C-terminus (aa 264-313) of M protein interacted with the extra-terminal (ET) domain of chicken bromodomain-containing protein 2 (chBRD2), which promoted NDV replication by downregulating chBRD2 expression and facilitating viral RNA synthesis and transcription. However, the key amino acid sites determining M's interaction with chBRD2/ET and their roles in the replication and pathogenicity of NDV are not known. In this study, three basic residues-R283, R286, and K288-in the NDV M protein were verified to be responsible for its interaction with chBRD2/ET. In addition, mutation of these basic residues (R283A/R286A/K288A) in the M protein changed its electrostatic pattern and abrogated the decreased expression of endogenic chBRD2. Moreover, a recombinant virus harboring these mutations resulted in a pathotype change of NDV and attenuated viral replication and pathogenicity in chickens due to the decreased viral RNA synthesis and transcription. Our findings therefore provide a better understanding of the crucial biological functions of M's basic residues and also aid in understanding the poorly understood pathogenesis of NDV.

Abstract
Viperin is an important virus-induced protein in animals that negatively participates in RNA viral replication and transcription. The reactive machinery of viperin suggests that it produces a regulatory molecule ddhCTP, which may affect immune regulation. In this study, we investigated the expression pattern of viperin in larval and adult stages of zebrafish by whole-mount in situ hybridization and reverse transcription-quantitative PCR (RT-qPCR). To elucidate the function of viperin, we generated a zebrafish knockout model using the CRISPR/Cas9 method and evaluated the mutation's effects under viral hemorrhagic septicemia virus (VHSV) infections. In zebrafish larvae, viperin was expressed in the brain region, eye, and pharynx, which was confirmed by cryosectioning. In adult zebrafish, blood cells showed the highest levels of viperin expression. In 5 dpf fish challenged with VHSV, the expression of the viral NP protein was significantly enhanced in viperin-/- compared to wild-type fish. In vitro VHSV propagation analysis indicated comparatively higher levels of virus propagation in viperin-/- fish. Mortality analysis confirmed higher mortality rates, and interferon gene expression analysis showed a strong upregulation of interferon (ifn)φ1 and 3 gene in viperin-/- fish infected with VHSV. This study describes the successful generation of a viperin-knockout model and the role of viperin during VHSV infections.

Abstract
The matrix (M) protein of several cytoplasmic RNA viruses has been reported to be an NF-κB pathway antagonist. However, the function and mechanism of NDV M protein antagonizing NF-κB activation remain largely unknown. In this study, we found that the expression levels of IRAK4, TRAF6, TAK1, and RELA/p65 were obviously reduced late in NDV infection. In addition, the cytoplasmic M protein rather than other viral proteins decreased the expression of these proteins in a dose-dependent manner. Further indepth analysis showed that the N-terminal 180 amino acids of M protein were not only responsible for the reduced expression of these proteins, but also responsible for the inhibition of NF-κB activation and nuclear translocation of RELA/p65, as well as the production of inflammatory cytokines. Moreover, small interference RNA-mediated knockdown of IRAK4 or overexpression of IRAK4 markedly enhanced or reduced NDV replication by decreasing or increasing inflammatory cytokines production through the IRAK4/TRAF6/TAK1/NF-κB signaling pathway. Strangely, there were no interactions detected between NDV M protein and IRAK4, TRAF6, TAK1 or RELA/p65. Our findings described here contribute to a better understanding of the innate immune antagonism function of M protein and the molecular mechanism underlying the replication and pathogenesis of NDV.

Abstract
Pigeon paramyxovirus type 1 (PPMV-1) belongs to the avian paramyxovirus type 1 group of viruses, which can cause tremors, torticollis, and respiratory signs in domestic and wild pigeons. The M protein of PPMV-1 is a multifunctional structural protein. It not only helps in the assembly, budding, and positioning of the virus but also inhibits the host's immune response and promotes replication of the virus in the host. In this study, the GST pull-down method was used to screen host proteins that interact with PPMV-1 M protein, and then mass spectrometry (MS) was used to analyse the screened host proteins. Enrichment analysis of the differentially expressed genes showed that the 77 screened proteins were highly associated with the gene ontology categories: protein synthesis, metabolism, and cell signalling pathway transduction. We selected NIMA-related kinase 7 (NEK7) as the candidate protein for co-localization analysis and co-immunoprecipitation verification. The results revealed that PPMV-1 M protein interacts with NEK7 of the host cell. This interactome study of PPMV-1 M protein will serve to clarify its function during viral replication and will provide a crucial theoretical basis for studying the pathogenic mechanism of PPMV-1.

Abstract
Thrombotic diseases have been considered major causes of death around the world. Treatments with thrombolytic drugs, such as recombinant tissue-plasminogen activator, urokinase, and streptokinase, are reported to have a life-threatening bleeding tendency. On the contrary, lumbrokinase, identified from Lumbricus rubellus, is specific to fibrin and does not cause excessive bleeding. It possesses fibrinolytic activity and activation of plasminogen to dissolve fibrin. Hence, the purification of fibrinolytic protein monomer from earthworm and antithrombotic evaluation and investigation of mechanisms are needed. In this study, a novel fibrinolytic protein EPF3, with strong fibrinolytic activity, was purified from Pheretima vulgaris by ion exchange and size exclusion chromatography. SDS PAGE, bottom-up proteomics analysis, de novo sequencing, and circular dichroism (CD) analysis were carried out for identification and characterization of it. EPF3, with a molecular weight of 25136.24 Da, consisted of 241 amino acids and contained various forms of secondary structures, including α-helix (3.9%), β-sheet (42.8%), β-turn (21.2%), and random coil (32.1%). It was a trypsin-like serine protease and stable at pH 7.0 to 11.0 and below 40°C. EPF3 was confirmed to possess an antithrombotic effect by ex vivo clot lysis test and fibrinogen-thrombin time (Fib-TT) assay. The three-dimensional structure of EPF3 was predicted by SWISS-MODEL. Molecular docking analysis predicted that EPF3 could directly interact with antithrombotic target proteins (fibrin, fibrinogen, and plasminogen), which was further confirmed by further studies. The antithrombotic mechanism of EPF3 was clarified to be outstanding direct fibrinolysis, fibrinogenolytic activity, and certain activation of plasminogen. EPF3 possesses the potential to be developed into a promising antithrombotic agent.

Abstract
ABSTRACTNumerous studies have shown that viruses can utilize or manipulate ribosomal proteins to achieve viral protein biosynthesis and replication. In our recent studies using proteomics analysis of virus-infected cells, we found that ribosomal protein L18 (RPL18) was the highest up-regulated differentially expressed protein, which was along with the increasingly expressed viral proteins later in Newcastle disease virus (NDV) infection. However, the association of RPL18 with viral protein biosynthesis and NDV replication remains unclear. In this study, we found that the expression and transcription levels of RPL18 was reduced early in NDV infection but increased later in NDV infection. In addition, the presence of cytoplasmic NDV matrix (M) protein was responsible for the increased expression of RPL18 in both virus-infected cells and plasmid-transfected cells. Moreover, cytoplasmic M protein increased RPL18 expression in a dose-dependent manner, even though they did not interact with each other. Furthermore, siRNA-mediated knockdown of RPL18 or overexpression of RPL18 dramatically reduced or enhanced NDV replication by decreasing or increasing viral protein translation rather than viral RNA synthesis and transcription. Taken together, these results suggested that the increased expression of RPL18 might be associated with the physical clumping together of the M protein, which in turn promoted viral protein biosynthesis and NDV replication, thus revealing for the first time the association of RPL18 with NDV M protein was important for viral translation and replication.

Abstract
Avian reovirus (ARV) can induce many diseases as well as immunosuppression in chickens, severely endangering the poultry industry. Interferons (IFNs) play an antiviral role by inducing the expression of interferon-stimulated genes (ISGs). The effect of ARV infection on the expression of host ISGs is unclear. Specific-pathogen-free (SPF) chickens were infected with ARV strain S1133 in this study, and real time quantitative PCR was used to detect changes in the dynamic expression of IFNs and common ISGs in joints of SPF chickens. The results showed that the transcription levels of IFNA, IFNB, and several ISGs, including myxovirus resistance (MX), interferon-induced transmembrane protein 3 (IFITM3), protein kinase R (PKR), oligoadenylate synthase (OAS), interferon-induced protein with tetratricopeptide repeats 5 (IFIT5), interferon-stimulated gene 12 (ISG12), virus inhibitory protein (VIPERIN), interferon-alpha-inducible protein 6 (IFI6), and integrin-associated protein (CD47), were upregulated in joints on days 1–7 of infection (the levels of increase of MX, IFIT5, OAS, VIPERIN, ISG12, and IFI6 were the most significant, at hundreds-fold). In addition, the expression levels of the ISGs encoding zinc finger protein 313 (ZFP313), and DNA damage–inducible transcript 4 (DDIT4) increased suddenly on the 1st or 2nd day, then decreased to control levels. The ARV viral load in chicken joints rapidly increased after 1 day of viral challenge, and the viral load remained high within 6 days of viral challenge. The ARV viral load sharply decreased starting on day 7. These results indicate that in SPF chicken joints, many ISGs have mRNA expression patterns that are basically consistent with the viral load in joints. IFNA, IFNB, and the ISGs MX, IFITM3, PKR, OAS, IFIT5, ISG12, VIPERIN, IFI6, and CD47 play important roles in defending against ARV invasion, inhibiting ARV replication and proliferation, and promoting virus clearance. These results enrich our understanding of the innate immune response mechanisms of hosts against ARV infection and provide a theoretical basis for prevention and control of ARV infection.

Towards Improved Use of Vaccination in the Control of Infectious Bronchitis and Newcastle Disease in Poultry: Understanding the Immunological Mechanisms. Vaccines (Basel) 2021; 9:vaccines9010020. [PMID: 33406695 PMCID: PMC7823560 DOI: 10.3390/vaccines9010020] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2020] [Revised: 12/24/2020] [Accepted: 12/29/2020] [Indexed: 12/11/2022] Open
Abstract
Infectious bronchitis (IB) and Newcastle disease (ND) are two important diseases of poultry and have remained a threat to the development of the poultry industry in many parts of the world. The immunology of avian has been well studied and numerous vaccines have been developed against the two viruses. Most of these vaccines are either inactivated vaccines or live attenuated vaccines. Inactivated vaccines induce weak cellular immune responses and require priming with live or other types of vaccines. Advanced technology has been used to produce several types of vaccines that can initiate prime immune responses. However, as a result of rapid genetic variations, the control of these two viral infections through vaccination has remained a challenge. Using various strategies such as combination of live attenuated and inactivated vaccines, development of IB/ND vaccines, use of DNA vaccines and transgenic plant vaccines, the problem is being surmounted. It is hoped that with increasing understanding of the immunological mechanisms in birds that are used in fighting these viruses, a more successful control of the diseases will be achieved. This will go a long way in contributing to global food security and the economic development of many developing countries, given the role of poultry in the attainment of these goals.

Abstract
Newcastle disease is a severe clinical manifestation of avian species caused by Newcastle disease virus (NDV). Although several vaccination strategies are available to protect poultry against NDV infection, even then, outbreaks have been reported in the vaccinated birds. The lack of therapeutics against NDV makes the need for effective anti-viral drugs is of utmost importance. Lithium Chloride (LiCl) is a widely prescribed drug for the treatment of bipolar disorder, acute brain injuries, and chronic neurodegenerative diseases. Also, LiCl has been repurposed as an effective anti-viral drug for some viral infections. In the present work, we have investigated the efficacy of LiCl to inhibit NDV replication using in vitro, in ovo, and in vivo models. Our results collectively showed the modulation of NDV replication after the LiCl treatment. We also demonstrated that NDV induces endoplasmic reticulum stress (ER-stress), and a stress-inducible ER chaperone, glucose-regulating protein 78 (GRP78), was found to be over-expressed after NDV infection. Subsequently, the treatment of NDV infected cells with LiCl significantly reduced the transcript and protein levels of GRP78. Finally, we concluded that LiCl treatment protects the cells from ER-stress induced by the NDV infection.

Vet Res 2020; 51:120. [PMID: 32962745 PMCID: PMC7509934 DOI: 10.1186/s13567-020-00846-1] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Accepted: 09/10/2020] [Indexed: 12/23/2022] Open
Abstract
Bromodomain-containing protein 2 (BRD2) is a nucleus-localized serine-threonine kinase that plays pivotal roles in the transcriptional control of diverse genes. In our previous study, the chicken BRD2 (chBRD2) protein was found to interact with the Newcastle disease virus (NDV) matrix (M) protein using a yeast two-hybrid screening system, but the role of the chBRD2 protein in the replication of NDV remains unclear. In this study, we first confirmed the interaction between the M protein and chBRD2 protein using fluorescence co-localization, co-immunoprecipitation and pull-down assays. Intracellular binding studies indicated that the C-terminus (aa 264-313) of the M protein and the extra-terminal (ET) domain (aa 619-683) of the chBRD2 protein were responsible for interactions with each other. Interestingly, although two amino acids (T621 and S649) found in the chBRD2/ET domain were different from those in the human BRD2/ET domain and in that of other mammals, they did not disrupt the BRD2-M interaction or the chBRD2-M interaction. In addition, we found that the transcription of the chBRD2 gene was obviously decreased in both NDV-infected cells and pEGFP-M-transfected cells in a dose-dependent manner. Moreover, small interfering RNA-mediated knockdown of chBRD2 or overexpression of chBRD2 remarkably enhanced or reduced NDV replication by upregulating or downregulating viral RNA synthesis and transcription, respectively. Overall, we demonstrate for the first time that the interaction of the M protein with the chBRD2 protein in the nucleus promotes NDV replication by downregulating chBRD2 expression and facilitating viral RNA synthesis and transcription. These results will provide further insight into the biological functions of the M protein in the replication of NDV.

Abstract
Viperin plays an important and multifaceted role in the innate immune response to viral infection. Viperin is also notable as one of very few radical SAM-dependent enzymes present in higher animals; however, the enzyme appears broadly conserved across all kingdoms of life, which suggests that it represents an ancient defense mechanism against viral infections. Although viperin was discovered some 20 years ago, only recently was the enzyme's structure determined and its catalytic activity elucidated. The enzyme converts CTP to 3'-deoxy-3',4'-didehydro-CTP, which functions as novel chain-terminating antiviral nucleotide when misincorporated by viral RNA-dependent RNA polymerases. Moreover, in higher animals, viperin interacts with numerous other host and viral proteins, and it is apparent that this complex network of interactions constitutes another important aspect of the protein's antiviral activity. An emerging theme is that viperin appears to facilitate ubiquitin-dependent proteasomal degradation of some of the proteins it interacts with. Viperin-targeted protein degradation contributes to the antiviral response either by down-regulating various metabolic pathways important for viral replication or by directly targeting viral proteins for degradation. Here, we review recent advances in our understanding of the structure and catalytic activity of viperin, together with studies investigating the interactions between viperin and its target proteins. These studies have provided detailed insights into the biochemical processes underpinning this unusual enzyme's wide-ranging antiviral activity. We also highlight recent intriguing reports that implicate a broader role for viperin in regulating nonpathological cellular processes, including thermogenesis and protein secretion.

Abstract
In this study, the antithrombotic protein, named DPf3, was purified from Pheretima guillelmi by ion-exchange chromatography. The protein pattern of DPf3 was mainly at 26-34 kDa; its two main proteins, DPf3 ID NO.1 and NO.2, were detected to be 36,121.745 Da and 24,485.004 Da consisting of 329 and 241 amino acids, respectively; the full covered protein sequences were consistent with Ac44553_g1_i1_1 and Dc43026_g1_i1_2 in our previous constructed P. guillelmi local database. The secondary structure of DPf3 is the mixture of α-helix (0.19), β-sheet (0.30) and random coil (0.51). DPf3 was predicted to possess a direct effect on fibrin, fibrinogen and plasminogen by protein-protein docking analysis, which was further confirmed by in vitro and ex vivo study. DPf3 was determined to possess antithrombotic ability by showing outstanding direct-hydrolysis ability on fibrin, fibrinogen and blood clot, and slight plasminogen activation activity. DPf3 could significantly prolong APTT and decrease fibrinogen content, indicating that DPf3 exerted antithrombotic activity via the intrinsic and/or common pathway, and the third coagulation phase. By this approach, the functional protein DPf3 was fully revealed and found to confer excellent anticoagulant and thrombolytic activity, and could be developed into a promising antithrombotic agent.

Abstract
Tetherin/BST-2 is an antiviral protein that blocks the release of enveloped viral particles by linking them to the membrane of producing cells. At first, BST-2 genes were described only in humans and other mammals. Recent work identified BST-2 orthologs in nonmammalian vertebrates, including birds. Here, we identify the BST-2 sequence in domestic chicken (Gallus gallus) for the first time and demonstrate its activity against avian sarcoma and leukosis virus (ASLV). We generated a BST-2 knockout in chicken cells and showed that BST-2 is a major determinant of an interferon-induced block of ASLV release. Ectopic expression of chicken BST-2 blocks the release of ASLV in chicken cells and of human immunodeficiency virus type 1 (HIV-1) in human cells. Using metabolic labeling and pulse-chase analysis of HIV-1 Gag proteins, we verified that chicken BST-2 blocks the virus at the release stage. Furthermore, we describe BST-2 orthologs in multiple avian species from 12 avian orders. Previously, some of these species were reported to lack BST-2, highlighting the difficulty of identifying sequences of this extremely variable gene. We analyzed BST-2 genes in the avian orders Galliformes and Passeriformes and showed that they evolve under positive selection. This indicates that avian BST-2 is involved in host-virus evolutionary arms races and suggests that BST-2 antagonists exist in some avian viruses. In summary, we show that chicken BST-2 has the potential to act as a restriction factor against ASLV. Characterizing the interaction of avian BST-2 with avian viruses is important in understanding innate antiviral defenses in birds.IMPORTANCE Birds are important hosts of viruses that have the potential to cause zoonotic infections in humans. However, only a few antiviral genes (called viral restriction factors) have been described in birds, mostly because birds lack counterparts of highly studied mammalian restriction factors. Tetherin/BST-2 is a restriction factor, originally described in humans, that blocks the release of newly formed virus particles from infected cells. Recent work identified BST-2 in nonmammalian vertebrate species, including birds. Here, we report the BST-2 sequence in domestic chicken and describe its antiviral activity against a prototypical avian retrovirus, avian sarcoma and leukosis virus (ASLV). We also identify BST-2 genes in multiple avian species and show that they evolve rapidly in birds, which is an important indication of their relevance for antiviral defense. Analysis of avian BST-2 genes will shed light on defense mechanisms against avian viral pathogens.

Abstract
Chicken type I interferons (type I IFNs) are key antiviral players of the chicken immune system and mediate the first line of defense against viral pathogens infecting the avian species. Recognition of viral pathogens by specific pattern recognition receptors (PRRs) induce chicken type I IFNs expression followed by their subsequent interaction to IFN receptors and induction of a variety of IFN stimulated antiviral proteins. These antiviral effectors establish the antiviral state in neighboring cells and thus protect the host from infection. Three subtypes of chicken type I IFNs; chIFN-α, chIFN-β, and a recently discovered chIFN-κ have been identified and characterized in chicken. Chicken type I IFNs are activated by various host cell pathways and constitute a major antiviral innate defense in chicken. This review will help to understand the chicken type 1 IFNs, host cellular pathways that are involved in activation of chicken type I IFNs and IFN stimulated antiviral effectors along with the gaps in knowledge which will be important for future investigation. These findings will help us to comprehend the role of chicken type I IFNs and to develop different strategies for controlling viral infection in poultry.

Abstract
Type III interferon (IFN-λ) has recently been shown to exert a significant antiviral impact against viruses in vertebrates. Avian leukosis virus subgroup J (ALV-J), which causes tumor disease and immunosuppression in infected chicken, is a retrovirus that is difficult to prevent and control because of a lack of vaccines and drugs. Here, we obtained chicken IFN-λ (chIFN-λ) using a silkworm bioreactor and demonstrated that chIFN-λ has antiviral activity against ALV-J infection of both chicken embryo fibroblast cell line (DF1) and epithelial cell line (LMH). We found that chIFN-λ triggered higher levels of particular type III interferon-stimulated genes (type III ISGs) including myxovirus resistance protein (Mx), viperin (RSAD2), and interferon-inducible transmembrane protein 3 (IFITM3) in DF1 and LMH cells. Furthermore, over-expression of Mx, viperin, and IFITM3 could inhibit ALV-J infection in DF1 and LMH cells. Therefore, these results suggested that the anti-ALV-J function of chIFN-λ was specifically implemented by induction of expression of type III ISGs. Our data identified chIFN-λ as a critical antiviral agent of ALV-J infection and provides a potentially and attractive platform for the production of commercial chIFN-λ.
