Abstract
Newcastle disease virus (NDV), an avian paramyxovirus, causes major economic losses in the poultry industry worldwide. NDV strains are classified as avirulent, moderately virulent, or virulent according to the severity of the disease they cause. In order to gain a deeper understanding of the molecular mechanisms of virus-host interactions, we conducted Illumina HiSeq-based RNA-Seq analysis on chicken embryo fibroblast (DF1) cells during the first 24 hours of infection with NDV strain Komarov. Comparative analysis of uninfected DF1 cells versus NDV-infected DF1 cells at 6, 12, and 24 h postinfection identified 462, 459, and 410 differentially expressed genes, respectively. The findings revealed an increase in the expression of genes linked to the MAPK signalling pathway in the initial stages of NDV infection. This overexpression potentially aids viral multiplication while hindering pathogen detection and subsequent immune responses from the host. Our findings provide initial insights into the early responses of DF1 cells to NDV infection.

Vet Immunol Immunopathol 2023; 265:110666. [PMID: 37979488 DOI: 10.1016/j.vetimm.2023.110666] [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: 08/09/2021] [Revised: 10/24/2023] [Accepted: 10/27/2023] [Indexed: 11/20/2023]
Abstract
China is the country with the largest amount of duck breeding as well as duck meat and egg production. In recent years, the emergence and spread of duck Tembusu virus (DTMUV) has become one of the important factors in reducing the amount of duck slaughter, which seriously endangers the duck breeding industry in our country. In-depth research on the mechanism of duck innate immunity facilitates the exploration of new models for the treatment of DTMUV infection. IRF1 can induce the expression of many antiviral immune factors in the animal organism and play an important role in the innate immune response. In this study, we used interfering RNA to knock down the IRF1 gene in DEF cells and then the cells were infected with DTMUV. We found that knockdown of IRF1 promoted DTMUV replication at an early stage and caused downregulation of the expression of several major pattern recognition receptors (PRRs), interleukins (IL), interferons (IFN), antiviral proteins, and MHC molecules by assay, showing that the duIRF1-mediated signaling pathway plays an extremely important role in DTMUV-induced host innate immunity. In addition, we constructed the recombinant expression plasmid pET32a(+)-duIRF1-His, and finally prepared the polyclonal antibody of duIRF1 with good specificity, hoping to provide a detection means for research on the mechanism of IRF1 in innate immunity in our laboratory and in this field.

RNA-Seq Profiling between Commercial and Indigenous Iranian Chickens Highlights Differences in Innate Immune Gene Expression. Genes (Basel) 2023; 14:genes14040793. [PMID: 37107551 PMCID: PMC10138050 DOI: 10.3390/genes14040793] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 03/17/2023] [Accepted: 03/20/2023] [Indexed: 03/29/2023] Open
Abstract
The purpose of the current study was to examine transcriptomic-based profiling of differentially expressed innate immune genes between indigenous and commercial chickens. In order to compare the transcriptome profiles of the different chicken breeds, we extracted RNA from blood samples of the Isfahan indigenous chicken (as indigenous) and Ross broiler chicken (as commercial) breeds. RNA-Seq yielded totals of 36,763,939 and 31,545,002 reads for the indigenous and commercial breeds, respectively, with clean reads then aligned to the chicken reference genome (Galgal5). Overall, 1327 genes were significantly differentially expressed, of which 1013 genes were upregulated in the commercial versus the indigenous breed, while 314 were more highly expressed in the indigenous birds. Furthermore, our results demonstrated that the SPARC, ATP6V0D2, IL4I1, SMPDL3A, ADAM7, TMCC3, ULK2, MYO6, THG1L and IRG1 genes were the most significantly expressed genes in the commercial birds and the PAPPA, DUSP1, PSMD12, LHX8, IL8, TRPM2, GDAP1L1, FAM161A, ABCC2 and ASAH2 genes were the most significant in the indigenous chickens. Of notable finding in this study was that the high-level gene expressions of heat-shock proteins (HSPs) in the indigenous breeds could serve as a guideline for future genetic improvement. This study identified genes with breed-specific expression, and comparative transcriptome analysis helped understanding of the differences in underlying genetic mechanisms between commercial and local breeds. Therefore, the current results can be used to identify candidate genes for further breed improvement.

[PMID: 36522721 PMCID: PMC9756622 DOI: 10.1186/s12917-022-03539-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Accepted: 12/01/2022] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Interferon regulatory factor 1 (IRF1) is an important transcription factor that activates the type I interferon (IFN-I) response and plays a vital role in the antiviral immune response. Although IRF1 has been identified in several mammals, little information related to its function in canines has been described. RESULTS In this study, canine IRF1 (CaIRF1) was cloned. After a series of bioinformatics analyses, we found that the CaIRF1 protein structure was similar to that of other animal IRF1 proteins, including a conserved DNA-binding domain (DBD), an IRF-association domain 2 (IAD2) domain and two nuclear localization signals (NLSs). An indirect immunofluorescence assay (IFA) revealed that CaIRF1 was mainly distributed in the nucleus. Overexpression of CaIRF1 in Madin-Darby canine kidney cells (MDCK) induced high levels of interferon β (IFNβ) and IFN-stimulated response element (ISRE) promoter activation and induced interferon-stimulated gene (ISG) expression. Subsequently, we assayed the antiviral activity of CaIRF1 against vesicular stomatitis virus (VSV) and canine parvovirus type-2 (CPV-2) in MDCK cells. Overexpression of CaIRF1 effectively inhibited the viral yields of VSV and CPV-2, while knocking down of CaIRF1 expression mildly increased viral gene copies. CONCLUSIONS CaIRF1 is involved in the cellular IFN-I signaling pathway and plays an important role in the antiviral response.

Abstract
The genome contributes to the uniqueness of an individual breed, and enables distinctive characteristics to be passed from one generation to the next. The allelic heterogeneity of a certain breed results in a different response to a pathogen with different genomic expression. Disease resistance in chicken is a polygenic trait that involves different genes that confer resistance against pathogens. Such resistance also involves major histocompatibility (MHC) molecules, immunoglobulins, cytokines, interleukins, T and B cells, and CD4+ and CD8+ T lymphocytes, which are involved in host protection. The MHC is associated with antigen presentation, antibody production, and cytokine stimulation, which highlight its role in disease resistance. The natural resistance-associated macrophage protein 1 (Nramp-1), interferon (IFN), myxovirus-resistance gene, myeloid differentiation primary response 88 (MyD88), receptor-interacting serine/threonine kinase 2 (RIP2), and heterophile cells are involved in disease resistance and susceptibility of chicken. Studies related to disease resistance genetics, epigenetics, and quantitative trait loci would enable the identification of resistance markers and the development of disease resistance breeds. Microbial infections are responsible for significant outbreaks and have blighted the poultry industry. Breeding disease-resistant chicken strains may be helpful in tackling pathogens and increasing the current understanding on host genetics in the fight against communicable diseases. Advanced technologies, such as the CRISPR/Cas9 system, whole genome sequencing, RNA sequencing, and high-density single nucleotide polymorphism (SNP) genotyping, aid the development of resistant breeds, which would significantly decrease the use of antibiotics and vaccination in poultry. In this review, we aimed to reveal the recent genetic basis of infection and genomic modification that increase resistance against different pathogens in chickens.

Abstract
Bats are natural hosts for various zoonotic viral diseases. However, they rarely show signs of disease infection with such viruses. During viral infection, members of the IRFs family induce the production of IFNβ and exert antiviral effects. However, the functions of bat interferon regulatory factors (IRFs) remain unclear. In this study, the Tadarida brasiliensis IRF1 (TbIRF1) gene was first cloned and a series of bioinformatics studies were conducted. Results showed that bat IRF1 protein sequence showed a low similarity with IRF1s from other species. RNA virus such as Newcastle disease virus (NDV-GFP), avian influenza virus (AIV) and vesicular stomatitis virus (VSV-GFP) infection of Tadarida brasiliensis 1 lung (TB 1 Lu) cells significantly promotes the expressions of IFNβ, PKR, and OAS1, and up-regulates the expression of TbIRF1. Overexpression of TbIRF1 markedly activates IFNβ promoter activity in a dose-dependent manner. Next, we constructed the TbIRF1 functional domain deletion plasmids and found that the DNA binding domain (DBD) is necessary for TbIRF1 to induce IFNβ expresison. In conclusion, the first bat IRF1 gene was cloned, and its functions in IFN induction were preliminarily identified.

Abstract
Influenza virus and coronavirus are two important respiratory viruses, which often cause serious respiratory diseases in humans and animals after infection. In recent years, highly pathogenic avian influenza virus (HPAIV) and SARS-CoV-2 have become major pathogens causing respiratory diseases in humans. Thus, an in-depth understanding of the relationship between viral infection and host innate immunity is particularly important to the stipulation of effective control strategies. As the first line of defense against pathogens infection, innate immunity not only acts as a natural physiological barrier, but also eliminates pathogens through the production of interferon (IFN), the formation of inflammasomes, and the production of pro-inflammatory cytokines. In this process, the recognition of viral pathogen-associated molecular patterns (PAMPs) by host pattern recognition receptors (PRRs) is the initiation and the most important part of the innate immune response. In this review, we summarize the roles of RNA sensors in the host innate immune response to influenza virus and coronavirus infections in different species, with a particular focus on innate immune recognition of viral nucleic acids in host cells, which will help to develop an effective strategy for the control of respiratory infectious diseases.

Avian IRF1 and IRF7 Play Overlapping and Distinct Roles in Regulating IFN-Dependent and -Independent Antiviral Responses to Duck Tembusu Virus Infection. Viruses 2022; 14:v14071506. [PMID: 35891486 PMCID: PMC9315619 DOI: 10.3390/v14071506] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2022] [Revised: 07/05/2022] [Accepted: 07/07/2022] [Indexed: 02/04/2023] Open
Abstract
Avian interferon regulatory factors 1 and 7 (IRF1 and IRF7) play important roles in the host’s innate immunity against viral infection. Our previous study revealed that duck tembusu virus (DTMUV) infection of chicken fibroblasts (DF1) and duck embryo fibroblasts (DEFs) induced the expression of a variety of IFN-stimulated genes (ISGs), including VIPERIN, IFIT5, CMPK2, IRF1, and IRF7. IRF1 was further shown to play a significant role in regulating the up-expression of VIPERIN, IFIT5, and CMPK2 and inhibiting DTMUV replication. In this study, we confirm, through overexpression and knockout approaches, that both IRF1 and IRF7 inhibit DTMUV replication, mainly via regulation of type I IFN expression, as well as the induction of IRF1, VIPERIN, IFIT5, CMPK2, and MX1. In addition, IRF1 directly promoted the expression of VIPERIN and CMPK2 in an IFN-independent manner when IRF7 and type I IFN signaling were undermined. We also found that non-structural protein 2B (NS2B) of DTMUV was able to inhibit the induction of IFN-β mRNA triggered by Newcastle disease virus (NDV) infection or poly(I:C) treatment, revealing a strategy employed by DTMUV to evade host’s immunosurveillance. This study demonstrates that avian IRF7 and IRF1 play distinct roles in the regulation of type I IFN response during DTMUV infection.

Abstract
Innate immunity is not only the first line of host defense against pathogenic infection, but also the cornerstone of adaptive immune response. Upon pathogenic infection, pattern recognition receptors (PRRs) of host engage pathogen-associated molecular patterns (PAMPs) of pathogens, which initiates IFN production by activating interferon regulatory transcription factors (IRFs), nuclear factor-kappa B (NF-κB), and/or activating protein-1 (AP-1) signal transduction pathways in host cells. In order to replicate and survive, pathogens have evolved multiple strategies to evade host innate immune responses, including IFN-I signal transduction, autophagy, apoptosis, necrosis, inflammasome and/or metabolic pathways. Some avian viruses may not be highly pathogenic but they have evolved varied strategies to evade or suppress host immune response for survival, causing huge impacts on the poultry industry worldwide. In this review, we focus on the advances on innate immune evasion by several important avian immunosuppressive viruses (infectious bursal disease virus (IBDV), Marek’s disease virus (MDV), avian leukosis virus (ALV), etc.), especially their evasion of PRRs-mediated signal transduction pathways (IFN-I signal transduction pathway) and IFNAR-JAK-STAT signal pathways. A comprehensive understanding of the mechanism by which avian viruses evade or suppress host immune responses will be of help to the development of novel vaccines and therapeutic reagents for the prevention and control of infectious diseases in chickens.

Abstract
Interferon regulatory factors (IRFs) play a key role in many aspects of immune response, and IRF1, IRF3, and IRF7 are positive regulators of IFN induction in mammals. However, IRF3, as the most critical regulatory factor in mammals, is naturally absent in birds, which attracts us to study the functions of other members of the avian IRF family. In the present study, we cloned goose IRF1 (GoIRF1) and conducted a series of bioinformatics analyses to compare the protein homology of GoIRF1 with that of IRF1 in other species. The overexpression of GoIRF1 in DF-1 cells induced the activation of IFN-β, and this activation is independent of the dosage of the transfected GoIRF1 plasmids. The overexpression of GoIRF1 in goose embryonic fibroblasts (GEFs) induced the expression of IFNs, proinflammatory cytokines, and IFN-stimulated genes (ISGs); it also inhibited the replication of green fluorescent protein (GFP)-tagged Newcastle disease virus (NDV) (NDV-GFP) and GFP-tagged vesicular stomatitis virus (VSV) (VSV-GFP). Our results suggest that GoIRF1 is an important regulator of IFNs, proinflammatory cytokines, and ISGs and plays a role in antiviral innate immunity in geese.

Abstract
The global outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is still ongoing, as is research on the molecular mechanisms underlying cellular infection by coronaviruses, with the hope of developing therapeutic agents against this pandemic. Other important respiratory viruses such as 2009 pandemic H1N1 and H7N9 avian influenza virus (AIV), influenza A viruses, are also responsible for a possible outbreak due to their respiratory susceptibility. However, the interaction of these viruses with host cells and the regulation of post-transcriptional genes remains unclear. In this study, we detected and analyzed the comparative transcriptome profiling of SARS-CoV-2, panH1N1 (A/California/07/2009), and H7N9 (A/Shanghai/1/2013) infected cells. The results showed that the commonly upregulated genes among the three groups were mainly involved in autophagy, pertussis, and tuberculosis, which indicated that autophagy plays an important role in viral pathogenicity. There are three groups of commonly downregulated genes involved in metabolic pathways. Notably, unlike panH1N1 and H7N9, SARS-CoV-2 infection can inhibit the m-TOR pathway and activate the p53 signaling pathway, which may be responsible for unique autophagy induction and cell apoptosis. Particularly, upregulated expression of IRF1 was found in SARS-CoV-2, panH1N1, and H7N9 infection. Further analysis showed SARS-CoV-2, panH1N1, and H7N9 infection-induced upregulation of lncRNA-34087.27 could serve as a competitive endogenous RNA to stabilize IRF1 mRNA by competitively binding with miR-302b-3p. This study provides new insights into the molecular mechanisms of influenza A virus and SARS-CoV-2 infection.

Abstract
Avian infectious bronchitis virus (IBV) is an important gammacoronavirus. The virus is highly contagious, can infect chickens of all ages, and causes considerable economic losses in the poultry industry worldwide. In the last few decades, numerous studies have been published regarding pathogenicity, vaccination, and host immunity-virus interaction. In particular, innate immunity serves as the first line of defense against invasive pathogens and plays an important role in the pathogenetic process of IBV infection. This review focuses on fundamental aspects of host innate immune responses after IBV infection, including identification of conserved viral structures and different components of host with antiviral activity, which could provide useful information for novel vaccine development, vaccination strategies, and intervention programs.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2021; 119:104048.

Abstract
DEAD-box helicase 5 (DDX5) plays a significant role in tumorigenesis and regulates viral replication of several viruses. An avian oncogenic herpesvirus, Marek's disease virus (MDV), is widely known to cause immunosuppression and lymphoma in chickens. However, the underlying mechanisms of how DDX5 plays a role in viral replication remain unclear. In this study, we show that MDV inhibits the production of interferon beta (IFN-β) in chicken embryo fibroblasts (CEFs) by increasing the expression level and promoting the nuclear aggregation of DDX5. We further reveal how DDX5 down-regulates melanoma differentiation-associated gene 5/toll-like receptor 3 signaling through the fundamental transcription factor, interferon regulatory factor 1. MDV replication is suppressed, and the production of IFN-β is promoted in the DDX5 absented CEFs. Taken together, our investigations demonstrate that MDV inhibits IFN-β production by targeting DDX5-mediated signaling to facilitate viral replication, which offers a novel insight into the mechanism by which an avian oncogenic herpesvirus replicates in chicken cells.

Abstract
Interferon regulatory factor 1 (IRF1) is an important regulator in controlling the transcription of type I interferon genes, and its functions have been well-characterized in mammals, birds and fish. However, little information is available regarding the function of amphibian IRF1. In this study, an IRF1 gene homolog named as Xt-IRF1 was identified in the Western clawed frog (Xenopus tropicalis), an amphibian model specie widely used for comparative immunology research. Xt-IRF1 and IRF1 in other vertebrates possess similar genomic structure and flanking genes, and were grouped together to form a separate clade in phylogenetic tree. In addition, Xt-IRF1 gene was constitutively expressed in all tissues examined, with the highest expression level observed in spleen, and was inducible after poly(I:C) stimulation. Importantly, the expression of Xt-IRF1 was markedly induced by recombinant type I interferon, and Xt-IRF1 induced a strong activation of both IFNβ and ISRE promoters. The present study opens the door to investigate the roles of IRF1 in amphibians, and thus contributes to a better understanding of the functional evolution of IRFs in lower tetrapods.

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
Mallard ducks are a natural host and reservoir of avian Influenza A viruses. While most influenza strains can replicate in mallards, the virus typically does not cause substantial disease in this host. Mallards are often resistant to disease caused by highly pathogenic avian influenza viruses, while the same strains can cause severe infection in humans, chickens, and even other species of ducks, resulting in systemic spread of the virus and even death. The differences in influenza detection and antiviral effectors responsible for limiting damage in the mallards are largely unknown. Domestic mallards have an early and robust innate response to infection that seems to limit replication and clear highly pathogenic strains. The regulation and timing of the response to influenza also seems to circumvent damage done by a prolonged or dysregulated immune response. Rapid initiation of innate immune responses depends on viral recognition by pattern recognition receptors (PRRs) expressed in tissues where the virus replicates. RIG-like receptors (RLRs), Toll-like receptors (TLRs), and Nod-like receptors (NLRs) are all important influenza sensors in mammals during infection. Ducks utilize many of the same PRRs to detect influenza, namely RIG-I, TLR7, and TLR3 and their downstream adaptors. Ducks also express many of the same signal transduction proteins including TBK1, TRIF, and TRAF3. Some antiviral effectors expressed downstream of these signaling pathways inhibit influenza replication in ducks. In this review, we summarize the recent advances in our understanding of influenza recognition and response through duck PRRs and their adaptors. We compare basal tissue expression and regulation of these signaling components in birds, to better understand what contributes to influenza resistance in the duck.

Abstract
Interferon regulatory factors (IRFs) are among the most important transcription mediators and have multiple biological functions, such as antiviral and antimicrobial defense, cell differentiation, immune modulation, and apoptosis. Three IRF family members (HaIRF4-like, HaIRF6, and HaIRF8) of the big belly seahorse (Hippocampus abdominalis) were molecularly and functionally characterized at the sequence and transcriptional level. The coding sequences of HaIRF4-like, HaIRF6, and HaIRF8 were 1214, 1485, and 1266 bp in length, encoding proteins of size 46.21, 55.32, and 47.56 kDa, respectively. Potential viral transcription and replication was detected against VHSV infection using qPCR in HaIRFs-transfected FHM cells. IRFs significantly reduced viral gene expression at 24 h and 48 h post infection and the expression of interferon-stimulated genes (ISGs) was modulated at transcriptional level upon HaIRF overexpression in FHM cells. Subcellular HaIRF localization was observed using GFP-tagged expression vectors in FHM cells. HaIRF4-like and HaIRF8 were localized to the nucleus, whereas HaIRF6 was observed in the cytoplasm. All three IRFs were ubiquitously expressed in all analyzed tissues of the big belly seahorse. The mRNA expression of IRF4-like, IRF6, and IRF8 increased significantly post injection in the blood and gills following LPS, poly (I:C), and Streptococcus iniae challenge. These findings demonstrate that seahorse IRFs are involved in host defense mechanisms against immune stimulants and HaIRFs induce interferon and ISGs which trigger antiviral activity against viral infections in the host.

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
There is increasing recognition that the underlying genetic variation contributing to complex traits influences transcriptional regulation and can be detected at a population level as expression quantitative trait loci. At the level of an individual, allelic variation in transcriptional regulation of individual genes can be detected by measuring allele-specific expression in RNAseq data. We reasoned that extreme variants in gene expression could be identified by analysis of inbred progeny with shared grandparents. Commercial chickens have been intensively selected for production traits. Selection is associated with large blocks of linkage disequilibrium with considerable potential for co-selection of closely linked "hitch-hiker alleles" affecting traits unrelated to the feature being selected, such as immune function, with potential impact on the productivity and welfare of the animals. To test this hypothesis that there is extreme allelic variation in immune-associated genes we sequenced a founder population of commercial broiler and layer birds. These birds clearly segregated genetically based upon breed type. Each genome contained numerous candidate null mutations, protein-coding variants predicted to be deleterious and extensive non-coding polymorphism. We mated selected broiler-layer pairs then generated cohorts of F2 birds by sibling mating of the F1 generation. Despite the predicted prevalence of deleterious coding variation in the genomic sequence of the founders, clear detrimental impacts of inbreeding on survival and post-hatch development were detected in only one F2 sibship of 15. There was no effect on circulating leukocyte populations in hatchlings. In selected F2 sibships we performed RNAseq analysis of the spleen and isolated bone marrow-derived macrophages (with and without lipopolysaccharide stimulation). The results confirm the predicted emergence of very large differences in expression of individual genes and sets of genes. Network analysis of the results identified clusters of co-expressed genes that vary between individuals and suggested the existence of trans-acting variation in the expression in macrophages of the interferon response factor family that distinguishes the parental broiler and layer birds and influences the global response to lipopolysaccharide. This study shows that the impact of inbreeding on immune cell gene expression can be substantial at the transcriptional level, and potentially opens a route to accelerate selection using specific alleles known to be associated with desirable expression levels.

Abstract
Avian species have immune system to fight invading pathogens. The immune system comprises innate and adaptive immunity. Innate immunity relies on pattern recognition receptors to sense particular molecules present in pathogens, i.e. pathogen-associated molecular patterns (PAMPs), or danger signals in the environment, i.e. danger-associated molecular patterns (DAMPs). Cytoplasmic retinoic acid-inducible gene I (RIG-I)-like receptors (RLRs) and nucleotide-binding oligomerization domain-like receptors (NLRs) are the sensors recognizing cytoplasmic PAMP and/or DAMP. Among common avian species, chickens do not have RIG-I whereas ducks and finches do. Therefore, the other RLR member, melanoma differentiation-associated gene 5 (MDA5), is believed to play an important role to recognize intracellular pathogens in chickens. Chicken MDA5 has been identified and its function determined. Chicken MDA5 maintains the same domain architecture compared with MDA5 analogs in other animal species. The expression of chicken MDA5 was upregulated when a synthetic double-stranded RNA (dsRNA), polyriboinosinic:polyribocytidylic acids (poly(I:C)), was transfected into chicken cells, whereas that did not change when cells were incubated with poly(I:C). The enhanced expression of chicken MDA5 in chicken cells upregulated the expression of chicken interferon-[Formula: see text] (IFN-[Formula: see text]). The infection of dsRNA infectious bursal disease virus (IBDV) in non-immune cells triggered the activation of chicken MDA5 signaling pathway, leading to the production of IFN-[Formula: see text] and subsequent response of IFN-stimulated genes. Furthermore, in immune cells like macrophages, chicken MDA5 participated in sensing the infection of IBDV by activating downstream antiviral genes and molecules and modulating adaptive immunity.On the contrary, one of cytoplasmic NLR member, NLR family pyrin domain containing 3 (NLRP3), was cloned and functionally characterized in chicken cells. Chicken NLRP3 conserved the same domain architecture compared with NLRP3 analogs in other animal species. Chicken NLRP3 was highly expressed in kidney, bursa of Fabricius and spleen. The production of mature chicken interleukin 1 [Formula: see text] (IL-1[Formula: see text] in chicken macrophages was stimulated by lipopolysaccharide (LPS) treatment followed by short ATP exposure.In summary, chicken MDA5 was a cytoplasmic dsRNA sensor that mediated the production of type I IFN upon ligand engagement, whereas NLRP3 sensed danger signals, such as ATP, in the cytoplasm and cleaved pro-IL-1[Formula: see text] to produce mature IL-1[Formula: see text]. Chicken MDA5 was not only involved in the activation of innate immune responses in non-immune and immune cells, but it also participated in modulating adaptive immunity in immune cells. Chicken NLRP3 participated in the production of mature chicken IL-1[Formula: see text] upon ligand engagement.

Abstract
Aves polyomavirus 1 (APV) causes inflammatory disease in psittacine birds, especially in young budgerigar. In this study, an APV virus (SD18 strain) was isolated from a diseased psittacine birds breeding facility. The full genome (4981 bp) of SD18 was determined and analyzed. Phylogenetic analysis of full genome sequences indicated all the APV strains form two groups. The SD18 strain showed close relationship with APV isolated from Poland, however, the other Chinese strains are located in group II, which suggested different genotypes APVs are co-circulating in China. Compared with the consensus sequence of APV full genome, the SD18 strain contains 13 nucleotide mutations, and 2 unique amino acid substitutions (R179M and Q382K) located in VP2/3 and Large T proteins. To explore the pathogenicity of the virus, the SD18 strain was used to challenge 2-week-old budgerigars. All infected birds died no later than 5 days post infection, and virus was detected in multiple organs including brain, heart, ingluvies, liver, and intestine, which indicated that SD18 is fatal and causes systemic infection in young budgerigar. In vitro studies showed that SD18 replicated efficiently in CEF cells and reached the highest viral titers at 9 days post infection. Notably, replication of SD18 stimulated IFN-β response in CEF cells and overexpression of the VP4 or VP4Delta proteins significantly inhibited IFN-β promoter activation, which could be the strategy of APV to escape from the host innate immunity.

Abstract
Newcastle disease virus (NDV), an avian paramyxovirus, was shown to prefer to replicate in tumor cells instead of normal cells; however, this mechanism has not been fully elucidated. Exosomes play a crucial role in intercellular communication due to the bioactive substances they carry. Several studies have shown that exosomes are involved in virus infections. However, the effect that exosomes have on NDV-infected tumor cells is not known. In this study, we focus on the role of exosomes secreted by NDV-infected HeLa cells in promoting NDV replication. Three miRNA candidates (miR-1273f, miR-1184, and miR-198) embraced by exosomes were associated with enhancing NDV-induced cytopathic effects on HeLa cells. Furthermore, luciferase assays, RT-qPCR, and enzyme-linked immunosorbent assay (ELISA) all demonstrated that these miRNAs could suppress interferon (IFN)-β gene expression. Enhanced NDV replication in HeLa cells was identified by Western blot and plaque assays. Based on these results, we speculate that NDV employed exosomes entry into neighboring cells, which carry miRNAs, resulting in inhibition of the IFN pathway and promotion of viral infection. To our knowledge, this is the first report on the involvement of NDV-employed exosomes in tumor cells, and as such, it provides new insights into the development of anti-tumor therapies.

Abstract
To investigate cytokine expression in chicken embryo fibroblast (CEF) cells, a virulent avian avulavirus 1 (AAvV-1) strain called SG10 that rapidly causes 100% mortality in its host, and a vaccine strain (La Sota) were characterized. Real-time quantitative PCR was performed on RNA samples from CEF cells, which were collected at 0, 24, 48 and 72 h post-infection. The dynamic expression patterns of ten cytokines (TNF-α, IFN-α, IFN-β, IL-1β, IL-2, IL-6, IL-10, IL-13, IL-15 and IL-18) were investigated. The results showed that infection with lentogenic La Sota induced significantly higher levels of the antiviral cytokines IFN-α and IFN-β, proinflammatory cytokines IL-2, IL-15 and IL-18, and the anti-inflammatory cytokine IL-10, than did infection with virulent SG10. Furthermore, the SG10 strain induced dramatically higher levels of the inflammatory cytokine IL-6 than those observed in cells infected with La Sota. However, the expression patterns of the other cytokines that were tested did not show any obvious trends or statistically significant differences between cells infected with the virulent and avirulent strains. These data show that infection with lentogenic La Sota induced more effective immune responses and anti-viral effects than did infection with virulent SG10 in CEFs. Our data provide distinct expression patterns of IFNs and proinflammatory and anti-inflammatory cytokines to AAvV-1 by virulence in CEF cells.
