Abstract
Bacterial infection involves a complex interaction between the pathogen and host where the outcome of infection is not solely determined by pathogen eradication. To identify small molecules that promote host survival by altering the host-pathogen dynamic, we conducted an in vivo chemical screen using zebrafish embryos and found that treatment with 3-hydroxykynurenine (3-HK) protects from lethal bacterial infection. 3-HK, a metabolite produced through host tryptophan metabolism, has no direct antibacterial activity but enhances host survival by restricting bacterial expansion in macrophages through a systemic mechanism that targets kainate-sensitive glutamate receptors. These findings reveal a new pathway by which tryptophan metabolism and kainate-sensitive glutamate receptors function and interact to modulate immunity, with important implications for the coordination between the immune and nervous systems in pathological conditions.

FEBS Open Bio 2024; 14:532-544. [PMID: 38321830 PMCID: PMC10988753 DOI: 10.1002/2211-5463.13769] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Revised: 11/23/2023] [Accepted: 01/11/2024] [Indexed: 02/08/2024] Open
Abstract
Unlike mammals, fish express two type II interferons, IFNγ and fish-specific IFNγ (IFNγ-related or IFNγrel). We previously reported the presence of two IFNγrel genes, IFNγrel 1 and IFNγrel 2, which exhibit potent antiviral activity in the Ginbuna crucian carp, Carassius auratus langsdorfii. We also found that IFNγrel 1 increased allograft rejection; however, the IFNγrel 1 receptor(s) and signaling pathways underlying this process have not yet been elucidated. In this study, we examined the unique signaling mechanism of IFNγrel 1 and its receptors. The phosphorylation and transcriptional activation of STAT6 in response to recombinant Ginbuna IFNγrel 1 (rgIFNγrel 1) was observed in Ginbuna-derived cells. Binding of rgIFNγrel 1 to Class II cytokine receptor family members (Crfbs), Crfb5 and Crfb17, which are also known as IFNAR1 and IFNGR1-1, respectively, was detected by flow cytometry. Expression of the IFNγrel 1-inducible antiviral gene, Isg15, was highest in Crfb5- and Crfb17-overexpressing GTS9 cells. Dimerization of Crfb5 and Crfb17 was detected by chemical crosslinking. The results indicate that IFNγrel 1 activates Stat6 through an interaction with unique pairs of receptors, Crfb5 and Crfb17. Indeed, this cascade is distinct from not only that of IFNγ but also that of known IFNs in other vertebrates. IFNs may be classified by their receptor and signal transduction pathways. Taken together, IFNγrel 1 may be classified as a novel type of IFN family member in vertebrates. Our findings provide important information on interferon gene evolution in bony fish.

Abstract
Type II interferons (IFNs) are a key class of molecules regulating innate and adaptive immunity in vertebrates. In the present study, two members of the type II IFNs, IFN-γ and IFNγ-rel, were identified in the blunt snout bream (Megalobrama amblycephala). The open reading frame (ORF) of IFN-γ and IFNγ-rel was found to have 564 bp and 492 bp, encoding 187 and 163 amino acids, with the first 26 and 24 amino acids being the signal peptide, respectively. IFN-γ and IFNγ-rel genes showed a high degree of similarity to their zebrafish homologues, being 76.9 % and 58.9 %, respectively. In the phylogenetic tree, IFN-γ and IFNγ-rel were clustered with homologous genes in cyprinids. In blunt snout bream, IFN-γ and IFNγ-rel were constitutively expressed in trunk kidney, head kidney, spleen, liver, heart, muscle, gill, intestine and brain and were significantly up-regulated by poly (I:C) induction in head kidney, spleen, liver, gill and intestine. Using recombinant proteins of IFN-γ and IFNγ-rel, the surface plasmon resonance (SPR) results showed that IFN-γ was bound to CRFB6, CRFB13 and CRFB17, but mainly to CRFB6 and CRFB13, whereas IFN-γrel bound mainly to CRFB17 and had no affinity with CRFB6. These results contribute to a better understanding on type II IFNs and their receptor usage in teleost fish.

Abstract
Type II interferons (IFNs) exert antiviral functions by binding to receptors and activating downstream signaling pathways. However, our understanding of the antiviral functions and the receptor complex model of type II IFNs in teleost fish remains limited. In this study, we determined the functions of type II IFNs (LmIFN-γ and LmIFN-γrel) in Lateolabrax maculatus and assessed their antiviral ability mediated by their combination with different cytokine receptor family B members (LmCRFB6, LmCRFB13, and LmCRFB17). After infection with largemouth bass ulcer syndrome virus (LBUSV), the expression levels of LmIFNs and LmCRFBs increased significantly in vitro and in vivo. Incubation or injection with LmIFNs-His activated the expressions of LmISG15, LmMx, and LmIRF1. LmIFN-γ and LmIFN-γrel both bound to the extracellular domains of the three CRFBs via Pull-down. Furthermore, LmIFN-γ combined with LmCRFB6, LmCRFB6+LmCRFB13, and LmCRFB6+LmCRFB13+LmCRFB17 and LmIFN-γrel combined with all combinations containing LmCRFB17 induced the transcription of downstream genes and reduced the number of LBUSV copies. Therefore, type II IFNs (LmIFN-γ and LmIFN-γrel) contribute to enhanced antiviral immunity in L. maculatus and that ligand-receptor combinations effectively suppress virus replication. These findings provide a reference for future studies of the signal transduction mechanism of type II IFNs in teleost fish.

Abstract
Type I interferons (IFNs) play a significant role in antiviral innate immunity. But, the antiviral function of IFNd is controversial in teleosts. Here, we identified three IFNd receptors belonging to cytokine receptor family B (LmCRFB1, LmCRFB2, and LmCRFB5) in spotted seabass (Lateolabrax maculatus). LmIFNd and its receptors were highly expressed in gill, spleen and head kidney tissues. Additionally, LmIFNd, its receptors, and their downstream signal genes (LmTYK2, LmJAK1, LmSTAT1, and LmSTAT2) were induced by infectious spleen and kidney necrosis virus (ISKNV) infection. Injection of recombinant protein (LmIFNd-His) in vivo and incubation with the LmIFNd-His in vitro both induced expressions of IFN-stimulated genes (LmISGs). IFNd-His had a dose-dependent protective effect on the activity of brain cells infected by ISKNV and reduced the number of ISNKV copies. LmIFNd-His also bound to extracellular domains of the three receptors in vitro in the pull-down assay. LmIFNd-His preferentially induced ISG expression through receptor complex LmCRFB1 and LmCRFB5, followed by LmCRFB2 and LmCRFB5, to induce the expressions of LmISGs. Our results show that LmIFNd can enhance the antiviral immune response of spotted seabass, and it uses receptor complex LmCRFB1 and LmCRFB5 as well as LmCRFB2 and LmCRFB5 to induce LmISG expression. It is the first study about the antiviral function of LmIFNd and its receptor complex in spotted seabass, and it provides a reference for further studies of the controversial anti-viral function of IFNd in teleosts.

Bacterial infection involves a complex interaction between the pathogen and host where the outcome of infection is not solely determined by pathogen eradication. To identify small molecules that promote host survival by altering the host-pathogen dynamic, we conducted an in vivo chemical screen using zebrafish embryos and found that treatment with 3-hydroxy-kynurenine protects from lethal gram-negative bacterial infection. 3-hydroxy-kynurenine, a metabolite produced through host tryptophan metabolism, has no direct antibacterial activity but enhances host survival by restricting bacterial expansion in macrophages by targeting kainate-sensitive glutamate receptors. These findings reveal new mechanisms by which tryptophan metabolism and kainate-sensitive glutamate receptors function and interact to modulate immunity, with significant implications for the coordination between the immune and nervous systems in pathological conditions.

Abstract
The class II cytokine receptor family members are receptors of class 2 helical cytokines in mammals, and are named cytokine receptor family B (CRFB) in fish. In zebrafish, sixteen members, including CRFB1, CRFB2 and CRFB4-17 were reported. With the availability of genome sequence, a total of nineteen CRFBs was identified in the blunt snout bream (Megalobrama amblycephala), including CRFB1, CRFB2, CRFB4-17 with the presence of three CRFB9 isoforms, and two CRFB14 isoforms. These CRFB molecules contain well conserved features, such as fibronectin type III (FNIII) domain, transmembrane and intracellular domains as other class II cytokine receptors, and are phylogenetically grouped into thirteen clades with their homologues from other species of fish. The CRFB genes were constitutively expressed in organs/tissues examined in the fish. The finding of more CRFB members in the bream may provide clues to understand possible receptor-ligand interaction and their diversity from an evolutionary point of view.

Abstract
Olfactory sensory neurons (OSNs) are constantly exposed to pathogens, including viruses. However, serious brain infection via the olfactory route rarely occurs. When OSNs detect a virus, they coordinate local antiviral immune responses to stop virus progression to the brain. Despite effective immune control in the olfactory periphery, pathogen-triggered neuronal signals reach the CNS via the olfactory bulb (OB). We hypothesized that neuronal detection of a virus by OSNs initiates neuroimmune responses in the OB that prevent pathogen invasion. Using zebrafish ( Danio rerio ) as a model, we demonstrate viral-specific neuronal activation of OSNs projecting into the OB, indicating that OSNs are electrically activated by viruses. Further, behavioral changes are seen in both adult and larval zebrafish after viral exposure. By profiling the transcription of single cells in the OB after OSNs are exposed to virus, we found that both microglia and neurons enter a protective state. Microglia and macrophage populations in the OB respond within minutes of nasal viral delivery followed decreased expression of neuronal differentiation factors and enrichment of genes in the neuropeptide signaling pathway in neuronal clusters. Pituitary adenylate-cyclase-activating polypeptide ( pacap ), a known antimicrobial, was especially enriched in a neuronal cluster. We confirm that PACAP is antiviral in vitro and that PACAP expression increases in the OB 1 day post-viral treatment. Our work reveals how encounters with viruses in the olfactory periphery shape the vertebrate brain by inducing antimicrobial programs in neurons and by altering host behavior.

Susceptibility and Permissivity of Zebrafish (Danio rerio) Larvae to Cypriniviruses. Viruses 2023; 15:v15030768. [PMID: 36992477 PMCID: PMC10051318 DOI: 10.3390/v15030768] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 03/08/2023] [Accepted: 03/10/2023] [Indexed: 03/19/2023] Open
Abstract
The zebrafish (Danio rerio) represents an increasingly important model organism in virology. We evaluated its utility in the study of economically important viruses from the genus Cyprinivirus (anguillid herpesvirus 1, cyprinid herpesvirus 2 and cyprinid herpesvirus 3 (CyHV-3)). This revealed that zebrafish larvae were not susceptible to these viruses after immersion in contaminated water, but that infections could be established using artificial infection models in vitro (zebrafish cell lines) and in vivo (microinjection of larvae). However, infections were transient, with rapid viral clearance associated with apoptosis-like death of infected cells. Transcriptomic analysis of CyHV-3-infected larvae revealed upregulation of interferon-stimulated genes, in particular those encoding nucleic acid sensors, mediators of programmed cell death and related genes. It was notable that uncharacterized non-coding RNA genes and retrotransposons were also among those most upregulated. CRISPR/Cas9 knockout of the zebrafish gene encoding protein kinase R (PKR) and a related gene encoding a protein kinase containing Z-DNA binding domains (PKZ) had no impact on CyHV-3 clearance in larvae. Our study strongly supports the importance of innate immunity-virus interactions in the adaptation of cypriniviruses to their natural hosts. It also highlights the potential of the CyHV-3-zebrafish model, versus the CyHV-3-carp model, for study of these interactions.

Identification of type II interferons and receptors in an osteoglossiform fish, the arapaima Arapaima gigas. DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2023; 139:104589. [PMID: 36403789 DOI: 10.1016/j.dci.2022.104589] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/04/2022] [Revised: 09/26/2022] [Accepted: 10/17/2022] [Indexed: 06/16/2023]
Abstract
In mammals, type II interferon (IFN; i.e. IFN-γ) signalling transduces through its specific receptors IFN-γR1 and IFN-γR2. In an osteoglossiform fish, the arapaima Arapaima gigas, three type II IFNs, IFN-γ-like, IFN-γ and IFN-γrel, and their four possible receptor subunits IFN-γR1-1, IFN-γR1-2, IFN-γR2-1 and IFN-γR2-2 were identified in this study. The three type II IFN genes are composed of four exons and three introns, and they all contain IFN-γ signature motif and signal peptide, with the presence of potential nuclear localization signal (NLS) in IFN-γ-like and IFN-γ. The IFN-γR1-1, IFN-γR1-2, IFN-γR2-1 and IFN-γR2-2 are composed of seven exons and six introns, with predicted IFN-γR1-1 and IFN-γR1-2 proteins containing JAK1 and STAT1 binding sites, and IFN-γR2-1 and IFN-γR2-2 containing JAK2 binding sites. Gene synteny analysis showed that the type II IFN and their receptor loci are duplicated in arapaima. All these genes were expressed constitutively in all organs/tissues examined, and responded to the stimulation of polyI:C. The prokaryotic recombinant IFN-γ-like, IFN-γ and IFN-γrel proteins can significantly induce the upregulation of immune-related genes in trunk kidney leucocytes. The ligand-receptor relationship analyses revealed that recombinant IFN-γ-like, IFN-γ, and IFN-γrel transduce downstream signalling through IFN-γR1-1/IFN-γR2-1, IFN-γR1-2/IFN-γR2-2, and IFN-γR1-1, respectively, in xenogeneic cells with the overexpression of original or chimeric receptors. In addition, tyrosine (Y) 366 and Y377 in the intracellular region may be essential for the function of IFN-γR1-2 and IFN-γR1-1, respectively. The finding of type II IFN system in A. gigas thus provides different knowledge in understanding the diversity and evolution of type II IFN ligand-receptor relationships in vertebrates.

Abstract
Inflammation is a hallmark of the physiological response to aggressions. It is orchestrated by a plethora of molecules that detect the danger, signal intracellularly, and activate immune mechanisms to fight the threat. Understanding these processes at a level that allows to modulate their fate in a pathological context strongly relies on in vivo studies, as these can capture the complexity of the whole process and integrate the intricate interplay between the cellular and molecular actors of inflammation. Over the years, zebrafish has proven to be a well-recognized model to study immune responses linked to human physiopathology. We here provide a systematic review of the molecular effectors of inflammation known in this vertebrate and recapitulate their modes of action, as inferred from sterile or infection-based inflammatory models. We present a comprehensive analysis of their sequence, expression, and tissue distribution and summarize the tools that have been developed to study their function. We further highlight how these tools helped gain insights into the mechanisms of immune cell activation, induction, or resolution of inflammation, by uncovering downstream receptors and signaling pathways. These progresses pave the way for more refined models of inflammation, mimicking human diseases and enabling drug development using zebrafish models.

Abstract
Introduction Suppressor of cytokine signaling 3 (SOCS3) is a critical component of the negative feedback regulation that controls signaling by cytokines and other factors thereby ensuring that important processes such as hematopoiesis and inflammation occur at appropriate levels. Methods To gain further insights into SOCS3 function, the zebrafish socs3b gene was investigated through analysis of a knockout line generated using CRISPR/Cas9-mediated genome editing. Results Zebrafish socs3b knockout embryos displayed elevated numbers of neutrophils during primitive and definitive hematopoiesis but macrophage numbers were not altered. However, the absence of socs3b reduced neutrophil functionality but enhanced macrophage responses. Adult socs3b knockout zebrafish displayed reduced survival that correlated with an eye pathology involving extensive infiltration of neutrophils and macrophages along with immune cell dysregulation in other tissues. Discussion These findings identify a conserved role for Socs3b in the regulation of neutrophil production and macrophage activation.

Abstract
IL-20 is a pleiotropic cytokine that belongs to the IL-10 family and has a variety of biological functions in tissue homeostasis and regulation of host immune defenses. It signals through a heterodimeric receptor composed of a subunit with a long intracellular domain (R1 type receptor) and a subunit with a short intracellular domain (R2 type receptor). In this study, the R1 type receptor (CiIL-20R1/CRFB8) and the R2 type receptor (CiIL-20R2/CRFB16) were identified in grass carp Ctenopharyngodon idella. Expression analysis revealed that IL-20R2 was highly expressed in the gills and skin in healthy fish. Infection with Flavobacterium columnare resulted in the downregulation of both receptors in the gill at 48 and 72 h, whilst infection with grass carp reovirus induced their expression in the head kidney and spleen at 72 h. In the primary head kidney leucocytes, the expression levels of IL-20R1 and IL-20R2 were decreased after stimulation with 250 ng/mL IL-1β but not affected by IFN-γ. Co-immunoprecipitation analysis showed that CiIL-20R2/CRFB16 but not CiIL-20R1/CRFB8 bound to CiIL-20L. Furthermore, it was shown that CiIL-20R1/CRFB8 was responsible for activating the phosphorylation of STAT3, whilst CiIL-20R2/CRFB16 was not involved. Structural modeling analysis showed that key residues involved in the interaction between IL-20 and receptors were highly conserved between grass carp and humans, suggesting that the signal transduction and functions of IL-20/IL-20R axis are evolutionarily conserved.

Abstract
Gene duplication leads to subfunctionalization of paralogs. In mammals, IFN-γ is the sole member of the type II IFN family and binds to a receptor complex consisting of IFN-γR1 and IFN-γR2. In teleost fish, IFN-γ and its receptors have been duplicated due to the teleost-specific whole-genome duplication event. In this study, the functions of an IFN-γ-related (IFN-γrel) cytokine were found to be partially retained relative to IFN-γ in grass carp (Ctenopharyngodon idella [CiIFN-γrel]). CiIFN-γrel upregulated the expression of proinflammatory genes but had lost the ability to activate genes involved in Th1 response. The results suggest that CiIFN-γrel could have been subfunctionalized from CiIFN-γ. Moreover, CiIFN-γrel induced STAT1 phosphorylation via interaction with duplicated homologs of IFN-γR1 (cytokine receptor family B [CRFB] 17 and CRFB13). Strikingly, CiIFN-γrel did not bind to the IFN-γR2 homolog (CRFB6). To gain insight into the subfunctionalization, the crystal structure of CiIFN-γrel was solved at 2.26 Å, revealing that it forms a homodimer that is connected by two pairs of disulfide bonds. Due to the spatial positions of helix A, loop AB, and helix B, CiIFN-γrel displays a unique topology that requires elements from two identical monomers to form a unit that is similar to IFN-γ. Further, mutagenesis analyses identified key residues interacting with CiIFN-γrel receptors and those required for the biological functions. Our study can help understand the subfunctionalization of duplicated IFN-γ paralogs in fish.

Abstract
In this work, we describe the complete repertoire of channel catfish, Ictalurus punctatus, IFNs and IFN receptor genes. Based on multiple genomic and transcriptomic resources we identified 16 type I IFN genes, which represent the six type I IFN subgroups previously defined in salmonids (a-f.) No representatives of subgroup h previously only found in percomorphs were identified. An expansion in copy numbers of subgroup d IFN genes was of particular interest, as this has not been reported in other fish species to date. Furthermore, we confirmed the presence of two type II ifn genes encoding orthologs of IFNγ and the teleost-specific IFNγRel. Six homologs of IFN type I receptor genes were found in an array that shows conserved synteny with human chromosome 21. Three homologs of type II IFN receptor genes were also identified. These type I and type II receptor sequences are compatible with the dual type I IFN receptors, and the potentially more complex type II IFN receptors described in teleosts. Our data provide a comprehensive resource for future studies of channel catfish innate antiviral immunity.

Abstract
Interferons (IFNs) are critical soluble factors in the immune system and are composed of three types, (I, II and III) that utilize different receptor complexes IFN-αR1/IFN-αR2, IFN-γR1/IFN-γR2, and IFN-λR1/IL-10R2, respectively. Here we identify IFN-υ from the genomic sequences of vertebrates. The members of class II cytokine receptors, IFN-υR1 and IL-10R2, are identified as the receptor complex of IFN-υ, and are associated with IFN-υ stimulated gene expression and antiviral activity in zebrafish (Danio rerio) and African clawed frog (Xenopus laevis). IFN-υ and IFN-υR1 are separately located at unique and highly conserved loci, being distinct from all other three-type IFNs. IFN-υ and IFN-υR1 are phylogenetically clustered with class II cytokines and class II cytokine receptors, respectively. Therefore, the finding of this IFN ligand-receptor system may be considered as a type IV IFN, in addition to the currently recognized three types of IFNs in vertebrates. Interferons are critical soluble components of the inflammatory process and are composed of three types with associated receptor complexes. Here the authors identify and characterise the type IV interferon, IFN-υ, and identify its associated receptors, denote functionality during in vivo infection and ascertain its genomic localisation.

Int J Mol Sci 2022; 23:ijms23042385. [PMID: 35216498 PMCID: PMC8875600 DOI: 10.3390/ijms23042385] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2021] [Revised: 02/11/2022] [Accepted: 02/16/2022] [Indexed: 12/14/2022] Open
Abstract
The IL-2 family of cytokines act via receptor complexes that share the interleukin-2 receptor gamma common (IL-2Rγc) chain to play key roles in lymphopoiesis. Inactivating IL-2Rγc mutations results in severe combined immunodeficiency (SCID) in humans and other species. This study sought to generate an equivalent zebrafish SCID model. The zebrafish il2rga gene was targeted for genome editing using TALENs and presumed loss-of-function alleles analyzed with respect to immune cell development and impacts on intestinal microbiota and tumor immunity. Knockout of zebrafish Il-2rγc.a resulted in a SCID phenotype, including a significant reduction in T cells, with NK cells also impacted. This resulted in dysregulated intestinal microbiota and defective immunity to tumor xenotransplants. Collectively, this establishes a useful zebrafish SCID model.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2021; 123:104132.

Abstract
The interferon receptor system in teleost fish is more complex than that in mammals. In the present study, we identified 13 cytokine receptor genes (10 interferon receptor genes and 3 IL10R2-like genes) from Chinese sturgeon (Acipenser sinensis) using RNA-sequencing. Sequence analysis indicated that these receptors had conserved domains, including signal peptides, FNⅢ, and transmembrane domains. Phylogenetic analysis suggested that they belonged to the cytokine receptor family. In the present study, we named them IFNAR1-like (CRFB5a, CRFB5b), IFNAR2-like (CRFB3a, CRFB3b), IFNGR1-like (IFNGR1), IFNGR2-like (CRFB6a, CRFB6b/IFNGR2-1, CRFB6c/IFNGR2-2, CRFB6d/IFNGR2-3, CRFB6e/IFNGR2-4) and IL10R2-like (CRFB4a, CRFB4b, CRFB4c), respectively. Constitutive expression analysis revealed that these receptor genes had potential functions in immune and non-immune tissue compartments. After stimulating with Poly (I:C), the expression fold changes of CRFB3a, CRFB4a, CRFB4b, CRFB5b, and CRFB6e/IFNGR2-4 in Chinese sturgeon were higher than those of other receptor genes, which revealed that these five genes had important functions in the immune process to resist virus invasion in the host. After stimulating with IFN gamma, the expression fold changes of CRFB3a, CRFB4a, and CRFB6b/IFNGR2-1 were higher than those other receptor genes. Based on other teleost fish interferon receptor models, we speculated that IFNAR1-like (CRFB5a, CRFB5b) and IFNAR2-like (CRFB3a, CRFB3b), comprised Chinese sturgeon type Ⅰ IFN receptors; and IFNGR1-like (IFNGR1) and IFNGR2-like (CRFB6/IFNGR2) comprised Chinese sturgeon type Ⅱ IFN receptors.

Abstract
The inflammatory response to viral infection in humans is a dynamic process with complex cell interactions that are governed by the immune system and influenced by both host and viral factors. Due to this complexity, the relative contributions of the virus and host factors are best studied in vivo using animal models. In this review, we describe how the zebrafish (Danio rerio) has been used as a powerful model to study host-virus interactions and inflammation by combining robust forward and reverse genetic tools with in vivo imaging of transparent embryos and larvae. The innate immune system has an essential role in the initial inflammatory response to viral infection. Focused studies of the innate immune response to viral infection are possible using the zebrafish model as there is a 4-6 week timeframe during development where they have a functional innate immune system dominated by neutrophils and macrophages. During this timeframe, zebrafish lack a functional adaptive immune system, so it is possible to study the innate immune response in isolation. Sequencing of the zebrafish genome has revealed significant genetic conservation with the human genome, and multiple studies have revealed both functional conservation of genes, including those critical to host cell infection and host cell inflammatory response. In addition to studying several fish viruses, zebrafish infection models have been developed for several human viruses, including influenza A, noroviruses, chikungunya, Zika, dengue, herpes simplex virus type 1, Sindbis, and hepatitis C virus. The development of these diverse viral infection models, coupled with the inherent strengths of the zebrafish model, particularly as it relates to our understanding of macrophage and neutrophil biology, offers opportunities for far more intensive studies aimed at understanding conserved host responses to viral infection. In this context, we review aspects relating to the evolution of innate immunity, including the evolution of viral pattern recognition receptors, interferons and interferon receptors, and non-coding RNAs.

Abstract
Interferons (IFNs) are proteins of vital importance in the body's immune response. They are formed in different types of cells and have been found in fish, amphibians, reptiles and mammals. Two types of IFN have been found in ray-finned fish (Superclass: Osteichthyes, Class: Actinopterygii) so far, i.e. IFN type I (IFN I) and IFN type II (IFN II), while the presence of IFN type III (IFN III), which is found in phylogenetically older cartilaginous fishes, was not confirmed in this taxonomic group of vertebrates. Currently, type I IFN in Actinopterygii is divided into three groups, I, II and III, within which there are subgroups. These cytokines in these animals show primarily antiviral activity through the use of a signalling pathway JAK-STAT (Janus kinases - Signal transducer and activator of transcription) and the ability to induce ISG (IFN-stimulated genes) expression, which contain ISRE complexes (IFN-stimulated response elements). On the other hand, in Perciformes and Cyprinidae, it was found that type I/I interferons also participate in the antimicrobial response, inter alia, by inducing the expression of the inducible nitric oxide synthase (iNOS) and influencing the production of reactive oxygen species (ROS) in cells carrying out the phagocytosis process.

Abstract
Type I interferons are a subset of cytokines playing central roles in host antiviral defense, and their effects depend on the interaction with the heterodimeric receptor complex. Surprisingly, two pairs of the receptor subunits, CRFB1 and CRFB5, and CRFB2 and CRFB5, have been identified in fish, but the studies about preferential receptor usage of different fish IFN subtypes are rather limited. In this study, the three receptor chains of type I IFNs named as On-CRFB1, On-CRFB2 and On-CRFB5 were identified in Nile tilapia, Oreochromis niloticus. These three genes were constitutively expressed in all tissues examined, with the highest expression level observed in muscle and liver, and were rapidly induced in liver following the stimulation of poly(I:C). Interestingly, it is possible that all three subtypes of tilapia IFNs are able to signal through two pairs of the receptor subunits, On-CRFB1 and On-CRFB5, and On-CRFB2 and On-CRFB5. More importantly, tilapia group I IFNs (On-IFNd and On-IFNh) preferentially signal through a receptor complex composed of On-CRFB1 and On-CRFB5, and group II IFNs (On-IFNc) preferentially signal through a receptor complex comprised of On-CRFB2 and On-CRFB5. The present study thus provides new insights into the receptor usage of group I and group II IFNs in fish.

Abstract
The use of zebrafish as a model for human conditions is widely recognized. Within the last couple of decades, the zebrafish has furthermore increasingly been utilized as a model for diseases in aquacultured fish species. The unique tools available in zebrafish present advantages compared to other animal models and unprecedented in vivo imaging and the use of transgenic zebrafish lines have contributed with novel knowledge to this field. In this review, investigations conducted in zebrafish on economically important diseases in aquacultured fish species are included. Studies are summarized on bacterial, viral and parasitic diseases and described in relation to prophylactic approaches, immunology and infection biology. Considerable attention has been assigned to innate and adaptive immunological responses. Finally, advantages and drawbacks of using the zebrafish as a model for aquacultured fish species are discussed.

Abstract
In fish, type I IFNs are classified into three groups, i.e. group one, group two and group three, and further separated into seven subgroups based on the number of conserved cysteines and phylogenetic relationships. In the present study, four type I IFNs, named as IFNϕ1, IFNϕ2, IFNϕ3, IFNϕ4, as reported in zebrafish, were identified in a cyprinid, the topmouth culter, Culter alburnus, a species introduced recently into China's aquaculture. These IFNs may be classified as IFNa, IFNc, IFNc and IFNd in a recent nomenclature, with IFNa and IFNd having two cysteines in group one, and IFNc four cysteines in group two. These IFNs, together with their possible receptors, IFNϕ1, IFNϕ2, IFNϕ3, IFNϕ4, and CRFB1, CRFB2 and CRFB5 have an open reading frame (ORF) of 540, 552, 567, 516 bp, and 1572, 1392, 1125 bp, respectively. These IFNs have high amino acid sequence identities, being 91.1-93.6% and 66.9-77.3%, with those in grass carp and zebrafish, respectively, and are expressed constitutively in organs/tissues examined in the fish. The expression of these IFNs can be further induced following poly (I:C) stimulation. However, the possible function of these IFNs and their signalling pathway are of interest for further research.

Abstract
Grouper is known as a highly economical teleost species in the Asian aquaculture industry; however, intensive culture activities easily cause disease outbreak, especially viral disease. For the prevention of viral outbreaks, interferon (IFN) is among the major defence systems being studied in different species. Fish type I IFNs are known to possess antiviral properties similar to mammalian type I IFNs. In order to stimulate antiviral function, IFN will bind to its cognate receptor, the type I interferon receptor (IFNAR), composed of heterodimeric receptor subunits known as IFNAR1 and IFNΑR2. The binding of type I interferon to receptors assists in the transduction of signals from the external to internal environments of cells to activate biological responses. In order to study the function of IFN, we first need to understand IFN receptors. In this study, we cloned and identified IFNAR1 in orange-spotted grouper (osgIFNAR1) and noted the up-regulated mRNA expression of the receptor and downstream effectors in the head kidney cells with cytokine treatment. The transcriptional expression of osgIFNAR1, which is characterised using polyinosinic-polycytidylic acid (poly[I:C]) and lipopolysaccharide (LPS) treatments, indicated the involvement of osgIFNAR1 in the immune response of grouper. The subcellular localisation of osgIFNAR1 demonstrated scattering across the grouper cell. Viral infection showed the negative feedback regulation of osgIFNAR1 in grouper larvae. Further loss of function of IFNAR1 showed a decreased expression of the virus. This study reported the identification of osgIFNAR1 and characterisation of receptor sensitivity towards immunostimulants, cytokine response, and viral challenge in the interferon pathway of orange-spotted grouper and possible different role of the receptor in viral production. Together, these results provide a frontline report of the potential function of osgIFNAR1 in the innate immunity of teleost.

[PMID: 32001352 DOI: 10.1016/j.fsi.2020.01.042] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/18/2019] [Revised: 01/02/2020] [Accepted: 01/22/2020] [Indexed: 06/10/2023]
Abstract
Hepcidin links iron metabolism with innate immunity during the inhibition of bacterial infection. Our previous studies had shown that recombinant hepcidin can significantly reduce the mortality rate of Ctenopharyngodon idella infected with Flavobacterium columnare under laboratory conditions. Here, we studied the preventive and therapeutic effects of feed supplemented with different doses of recombinant hepcidin on F. columnare-challenged C. idella reared in a cage culture environment. The results showed that in the prevention groups, 30 and 90 mg/kg of added purified and unpurified hepcidin respectively resulted in a higher survival rate in the early post-infection period, while 60 mg/kg of purified hepcidin significantly improved the survival rate in the therapy group (all compared to the control group). In the hepatopancreas, the expression of hepcidin and ferritin was significantly up-regulated, and the levels of ferroportin and serum iron were significantly decreased, especially in the therapy group. In addition, the expression of iron-related genes in spleen and intestine exhibited a similar trend to that in hepatopancreas. Meanwhile, immune genes were up-regulated to varying degrees, and the therapy group exhibited a significantly improved expression of pro-inflammatory cytokines and specific immunity. In summary, our study shows that different doses of recombinant hepcidin had protective effects against bacterial infection by regulating the iron distribution and immune gene expression, which provides a strong foundation for the application of recombinant hepcidin in aquaculture.

Abstract
Oligopeptide transporter 1 (Pept1) is located on the brush border membrane of the intestinal epithelium and plays an important role in dipeptide and tripeptide absorption from protein digestion. In this study, we cloned and characterized the cDNA sequence of Janus kinase 2 (JAK2) from Ctenopharyngodon idella. The expression patterns of JAK2 in various tissues and developmental stages were characterized by quantitative real-time PCR (qRT-PCR). The mRNA expression levels of JAK2 and Pept1 regulated by leptin in the intestine were also analyzed in vitro and in vivo. The cDNA sequence of JAK2 is 3378 bp in length, and the mRNA of JAK2 was broadly expressed in all tissues and embryonic stages of C. idella analyzed. In addition, we found that leptin regulated expression of JAK2 and Pept1 in the intestine; Pept1 expression was down-regulated by the JAK2 inhibitor AG490 in vivo and in vitro. Furthermore, luciferase experiments showed that overexpression of the JAK2 gene significantly upregulated the activity of the Pept1 5′ regulatory sequence in C. idella. In conclusion, these results may help in elucidating the regulatory effect of the leptin-mediated JAK2 pathway on intestinal Pept1 expression in C. idella and the molecular mechanism of peptide transport by the intestinal transporter Pept1 in fishes.

Abstract
Intracellular bacterial infections affect all vertebrates. Cultured fish are particularly vulnerable because no effective protection measures have been established since such infections emerged approximately 50 years ago. As in other vertebrates, the induction of cell-mediated immunity (CMI) plays an important role in protecting fish against infection. However, details of the mechanism of CMI induction in fish have not been clarified. In the present study, we focused on the production of interleukin 12 (IL-12), an important factor in CMI induction in fish. Using several different approaches, we investigated IL-12 regulation in amberjack (Seriola dumerili), the species most vulnerable to intracellular bacterial disease. The results of promoter assays and transcription factor gene expression analyses showed that the expression of interferon regulatory factor-1 (IRF-1) and activator protein-1 (AP-1) is necessary for IL-12 production. Phagocytosis of living cells (LCs) of Nocardia seriolae bacteria induced IL-12 production in neutrophils, accompanied by IRF-1 and AP-1 gene expression. Bacteria in which the exported repetitive protein (Erp)-like gene was deleted (Δerp-L) could not establish intracellular parasitism or induce IRF-1 and AP-1 expression or IL-12 production, despite being phagocytosed by neutrophils. These data suggest that IL-12 production is regulated by (i) two transcription factors, IRF-1 and AP-1, (ii) phagocytosis of LCs by neutrophils, and (iii) one or more cell components of LCs. Our results enhance the understanding of the immune response to intracellular bacterial infections in vertebrates and could facilitate the discovery of new agents to prevent intracellular bacterial disease.

Abstract
IFN-γ, as the sole member of mammalian type II IFN, is a multifunctional cytokine which exerts its effects through two distinct IFN-γ receptors, IFNGR1 and IFNGR2. However, in teleost fish, another IFN-γ homologous gene, namely IFN-γ related gene (IFN-γrel), has been identified. Although IFN-γ and IFN-γrel genes have been described in some fish species, many important aspects remain poorly understood in relation with their signalling and function. In the present study, IFN-γ and IFN-γrel, as well as their receptors, cytokine receptor family B (CRFB) 17, CRFB13, two of which are homologous to IFNGR1 in mammals, and CRFB6, homolomous to IFNGR2, have been characterized in mandarin fish, Siniperca chuatsi. It was revealed that the two type IFN members exhibit antiviral activity, and IFN-γ transduces downstream signalling through CRFB13 and CRFB6, while IFN-γrel interacts with CRFB17 to activate downstream signalling. Moreover, IFN-γ and IFN-γrel have been shown to exert antiviral biological activity in a STAT1-dependent manner. Intracellular domain analysis of CRFB17 and CRFB13 demonstrated that the Y386 tyrosine residue of CRFB13 is required for the activation of the IFN-γ-mediated biologic response, and the Y324 and Y370 residues in CRFB17 are required to activate IFN-γrel signalling.

Abstract
Interferon-gamma (IFN-ϒ) is probably one of the most relevant cytokines orchestrating the immune response in vertebrates. Although the activities mediated by this molecule are well known in mammals, several aspects of the IFN-ϒ system in teleosts remain a riddle to scientists. Numerous studies support a potentially similar role of the fish IFN-ϒ signalling pathway in some well-described immunological processes induced by this cytokine in mammals. Nevertheless, the existence in some teleost species of duplicated ifng genes and an additional gene derived from ifng known as interferon-γ-related (ifngrel), among other things, raises new interesting questions about the mode of action of these various molecules in fish. Moreover, certain IFN-ϒ-mediated activities recently observed in mammals are still fully unknown in fish. Another attractive but mainly unexplored curious property of IFN-ϒ in vertebrates is its potential dual role depending on the type of pathogen. In addition, some aspects mediated by this molecule could favour the resolution of a bacterial infection but be harmful in the context of a viral disease, and vice versa. This review collects old and new aspects of IFN-ϒ research in teleosts and discusses new questions and pathways of investigation based on recent discoveries in mammals.

Abstract
MicroRNA-223 is known as a myeloid-enriched anti-inflammatory microRNA that is dysregulated in numerous inflammatory conditions. Here, we report that neutrophilic inflammation (wound response) is augmented in miR-223-deficient zebrafish, due primarily to elevated activation of the canonical nuclear factor κB (NF-κB) pathway. NF-κB over-activation is restricted to the basal layer of the surface epithelium, although miR-223 is detected throughout the epithelium and in phagocytes. Not only phagocytes but also epithelial cells are involved in miR-223-mediated regulation of neutrophils' wound response and NF-κB activation. Cul1a/b, Traf6, and Tab1 are identified as direct targets of miR-223, and their levels rise in injured epithelium lacking miR-223. In addition, miR-223 is expressed in cultured human bronchial epithelial cells, where it also downregulates NF-κB signaling. Together, this direct connection between miR-223 and the canonical NF-κB pathway provides a mechanistic understanding of the multifaceted role of miR-223 and highlights the relevance of epithelial cells in dampening neutrophil activation.

Abstract
In mammals, virus infection of host cells triggers innate immune response, characterized by induction of interferon (IFN) and downstream IFN-stimulated genes (ISGs). The initiation of IFN antiviral response is dependent on host recognition of virus infection. In fish, similar IFN antiviral response is induced in response to RNA or DNA virus infection; however, the detailed mechanisms underlying recognition of a given virus and activation of downstream signaling remain largely unexplored. Using an infection model with Epithelioma papulosum cyprini (EPC) cells and spring viremia of carp virus (SVCV), a negative sense single-stranded RNA virus, we reported that fish RLR signaling pathway was involved in SVCV-triggered fish IFN response. IFN response was significantly initiated in EPC cells when infected with SVCV, as evidenced by activation of fish IFN promoters, upregulation of IFN and ISGs at mRNA and protein levels. However, function blockade of RIG-I and MDA5, two cytosolic receptors of fish RLR family, significantly attenuated the activation of fish IFN promoters and also the induction of fish IFN and ISGs by SVCV infection. Consistently, SVCV infection-triggered IFN response were blocked in EPC cells when transfected with the dominant negative mutants of pivotal RLR signaling factors, including MAVS, MITA, TBK1, IRF3 and IRF7. These results together shed light on the conservation of RLR-mediated IFN signaling that contributes to fish cells responding to RNA virus infection.

Abstract
In this study, we investigated the immune responses against Mycobacterium gordonae in ginbuna crucian carp. Cumulative mortality of ginbuna injected with 2.0 × 107 CFU of M. gordonae was 50% at 170 days post-infection. CD4-1, CD8α, T-bet and IFNγ2 gene expression levels were significantly upregulated in ginbuna injected with 1.9 × 108 CFU of M. gordonae at 21 and 28 days post-infection. The CD4-2 level did not change during the experiment. Granulomatous responses consisted of central macrophage accumulation and surrounding lymphocytes, and Ziehl-Neelsen-positive bacteria were observed in the trunk kidney of the challenged fish. Immunohistochemistry using anti-ginbuna IFNγs and anti-ginbuna CD4-1 polyclonal antibody revealed that the marginal lymphocytes were positive for CD4-1, and the IFNγ-producing cells surrounded the mycobacterial cell-laden phagocytes. These results suggest that CD4-1+ cells and IFNγ2 play important roles in the granulomatous inflammation against Mycobacterial infections in teleosts.

Abstract
Interferon regulatory factors (IRFs) are transcription factors of the interferon (IFN)-inducible signaling pathway essential for host immunity against antimicrobial infection by virus and bacteria. Interferon regulatory factor 3 (IRF3) regulates the expression of IFNs and IFN-stimulated genes by binding to the IFN stimulatory response element (ISRE). In this study, we analyze the thymus transcriptome of the mandarin fish Siniperca chuatsi and report the functional analysis of Irf3 from the thymus as an emerging model of antiviral approaches. The predicted S. chuatsi IRF3 (Sc-Irf3) protein has 465 amino acid residues and evolutionarily conserved domains and is clustered in the IRF3 subfamily on a phylogenetic tree. Sc-Irf3 upon transgenic expression was mainly found in the cytoplasm through Western blot analysis and microscopy, but it translocated to the nucleus after polyinosinic:polycytidylic acid (ploly I:C) treatment. Endogenous Sc-irf3 RNA expression was detected in all eight adult organs examined. Importantly, Sc-irf3 RNA expression was significantly upregulated by ploly(I:C) treatment in the adult organs. Concurrently, reporter assays revealed that Sc-Irf3 increased the transcriptional activity of the ifnβ promoter, a minimal ISRE-containing promoter, and ifn promoter of mandarin fish. Therefore, Sc-Irf3 plays a major role in the IFN immune defense system against virus infection.

Abstract
Granulocyte colony-stimulating factor receptor (G-CSFR), encoded by the CSF3R gene, represents a major regulator of neutrophil production and function in mammals, with inactivating extracellular mutations identified in a cohort of neutropenia patients unresponsive to G-CSF treatment. This study sought to elucidate the role of the zebrafish G-CSFR by generating mutants harboring these inactivating extracellular mutations using genome editing. Zebrafish csf3r mutants possessed significantly decreased numbers of neutrophils from embryonic to adult stages, which were also functionally compromised, did not respond to G-CSF, and displayed enhanced susceptibility to bacterial infection. The study has identified an important role for the zebrafish G-CSFR in maintaining the number and functionality of neutrophils throughout the life span and created a bona fide zebrafish model of nonresponsive neutropenia.

Abstract
Interferon gamma (IFN-γ) is one of the key players in the immune system of vertebrates. The evolution and properties of IFN-γ and its receptors in fish species are of special interest as they point to the origin of innate immunity in vertebrates. We studied the phylogeny, biophysical and structural properties of IFN-γ and its receptors. Our phylogeny analysis suggests the existence of two groups of IFN-γ related proteins, one specific for Acanthomorpha, the other for Cypriniformes, Characiformes and Siluriformes. The analysis further shows an ancient duplication of the gene for IFN-γ receptor 1 (IFN- γR1) and the parallel existence of the duplicated genes in all current teleost fish species. In contrast, only one gene can be found for receptor 2, IFN- γR2. The specificity of the interaction between IFN- γ and both types of IFN- γR1 was determined by microscale thermophoresis measurements of the equilibrium dissociation constants for the proteins from three fish species. The measured preference of IFN- γ for one of the two forms of receptor 1agrees with the bioinformatic analysis of the coevolution between IFN- γ and receptor 1. To elucidate structural relationships between IFN-γ of fish and other vertebrate species, we determined the crystal structure of IFN-γ from olive flounder (Paralichthys olivaceus, PoliIFN-γ) at crystallographic resolution of 2.3 Å and the low-resolution structures of Takifugu rubripes, Oreochromis niloticus, and Larimichthys crocea IFN-γ by small angle X-ray diffraction. The overall PoliIFN-γ fold is the same as the fold of the other known IFN- γ structures but there are some significant structural differences, namely the additional C-terminal helix G and a different angle between helices C and D in PoliIFN-γ.

Luo K, Zhang S, Tang D, Xia L, Gao W, Tian G, Qi Z, Xu Q, Zhang W. Analysis of the expression patterns of the cytokine receptor family B (CRFB) and interferon gamma receptor (IFNGR) in Dabry's sturgeon (Acipenser dabryanus).

Abstract
Teleost fish have more complex interferon receptor systems than mammals. In the present study, genes encoding four cytokine receptor family B (CRFBs) and two interferon gamma receptors (IFNGRs) in Dabry's sturgeon (Acipenser dabryanus) were identified by RNA-sequencing. Sequence analysis revealed that the Dabry's sturgeon CRFBs and IFNGRs contained several conserved characteristics features, including signal peptides and a transmembrane domain. Phylogenetic analysis suggested that they belong to the CRFB3, CRFB5, and IFNGR protein families, and were named CRFB3a, CRFB3b, CRFB5a, CRFB5b, IFNGR1, and IFNGR2. The expression patterns of the CRFB and IFNGR genes were investigated in Dabry's sturgeon. The expression levels of CRFB5a, CRFB5b, and IFNGR1 showed no significant changes, suggesting that those genes do not mediate embryonic development. By contrast, the high expression levels of CRFB3a, CRFB3b, and IFNGR2 in the fertilized egg, 16-cell phase, and initial blastula stage implied the existence of maternally expression in the oocyte and association with embryonic development. Tissue distribution analysis revealed that the CRFB and IFNGR proteins have potential functions in immune and non-immune tissue compartments. Comprehensive analysis in Dabry's sturgeon revealed that the expression fold changes of CRFB3a, CRFB3b, CRFB5a, and CRFB5b in Dabry's sturgeon stimulated with poly I:C were higher than those in fish administrated with lipopolysaccharide (LPS). Conversely, the fold changes IFNGRs mRNA levels stimulated with LPS were higher than those in fish administrated with poly I: C. CRFB5a and IFNGR2 genes showed the earliest responses to the poly I: C, and the CRFB5a and IFNGR1 genes showed the earliest responses to LPS. These results implied that CRFB5a has important role in the IFN immune response. Our findings indicated that the Dabry's sturgeon CRFB and IFNGR genes have important functions in antiviral and antibacterial immune responses. The differential responses of these genes to poly I: C and LPS implied differences in the defense mechanisms against viruses and bacteria.

Abstract
Polymeric immunoglobulin receptor (pIgR) functions in transporting polymeric immunoglobulin across epithelial cells into external secretion in animals. During animal evolution, fish was situated at a transition point on the phylogenetic spectrum between species possessing only innate immunity (i.e., invertebrates) and species depending heavily on adaptive immunity (i.e., mammals). Previous studies reported that fish and mammals significantly differ in pIgR. This review summarized the differences in pIgR structure, function, and transcriptional regulation between fish and mammals. A model of the transcriptional regulation of the pIgR gene was suggested. In this model, microbes could activate Toll-like receptor, trigger the cascade reactions in the signaling pathway, and then activate transcription factors that regulate pIgR expression through combining with the pIgR promoter. This review provides some suggestions for further studies on the function and regulatory mechanism of pIgR in fish and other animals.

Abstract
Overcrowding conditions and temperatures shifts regularly manifest in large-scale infections of farmed fish, resulting in economic losses for the global aquaculture industries. Increased understanding of the functional mechanisms of fish antimicrobial host defenses is an important step forward in prevention of pathogen-induced morbidity and mortality in aquaculture setting. Like other vertebrates, macrophage-lineage cells are integral to fish immune responses and for this reason, much of the recent fish immunology research has focused on fish macrophage biology. These studies have revealed notable similarities as well as striking differences in the molecular strategies by which fish and higher vertebrates control their respective macrophage polarization and functionality. In this review, we address the current understanding of the biological mechanisms of teleost macrophage functional heterogeneity and immunity, focusing on the key cytokine regulators that control fish macrophage development and their antimicrobial armamentarium.

Abstract
Viral diseases are responsible for high rates of mortality and subsequent economic losses in modern aquaculture. The nervous necrosis virus (NNV) produces viral encephalopathy and retinopathy (VER), which affects the central nervous system, is considered one of the most serious viral diseases in marine aquaculture. Although some studies have localized NNV in the retina cells, none has dealt with immunity in the retina. Thus, for the first time, we intravitreally infected healthy specimens of European sea bass (Dicentrarchus labrax) with NNV with the aim of characterizing the immune response in the retina. Ultrastructural analysis detected important retinal injuries and structure degradation, including pycnosis, hydropic degeneration and vacuolization in some cell layers as well as myelin sheaths in the optic nerve fibres. Immunohistochemistry demonstrated that NNV replicated in the eyes. Regarding retinal immunity, NNV infection elicited the transcription of genes encoding proteins involved in the interferon (IFN) and cell-mediated cytotoxicity (CMC) responses as well as B and T cell markers, demonstrating that viral replication influences innate and adaptive responses. Further studies are needed to understand the retina immunity and whether the main retinal function, vision, is affected by nodavirus.

Abstract
The blockade of phagolysosomal fusion is considered a critical mycobacterial strategy to survive in macrophages. However, viable mycobacteria have been observed in phagolysosomes during infection of cultured macrophages, and mycobacteria have the virulence determinant MarP, which confers acid resistance in vitro. Here we show in mice and zebrafish that innate macrophages overcome mycobacterial lysosomal avoidance strategies to rapidly deliver a substantial proportion of infecting bacteria to phagolysosomes. Exploiting the optical transparency of the zebrafish, we tracked the fates of individual mycobacteria delivered to phagosomes versus phagolysosomes and discovered that bacteria survive and grow in phagolysosomes, though growth is slower. MarP is required specifically for phagolysosomal survival, making it an important determinant for the establishment of mycobacterial infection in their hosts. Our work suggests that if pathogenic mycobacteria fail to prevent lysosomal trafficking, they tolerate the resulting acidic environment of the phagolysosome to establish infection. In vivo, newly infecting mycobacteria are rapidly trafficked to lysosomes within macrophages The mycobacterial acid tolerance determinant MarP enables lysosomal survival and growth Phagolysosomal mycobacteria can successfully establish infection, which is MarP dependent

Abstract
Two members of type II IFNs have been identified in fish, i.e. an IFN-γ gene as in other vertebrates and a unique IFN-γ related (IFN-γ rel) gene being solely present in fish. However, the signalling pathways involved in the down-stream signalling of type II IFNs in fish remains poorly described. In this study, the type II IFNs mediated IRF1 was investigated in zebrafish, and the true homologous gene of mammalian IRF1 in fish was revealed despite the report of so-called IRF1a and IRF1b in zebrafish. As revealed in overexpression analysis, zebrafish IFN-γ had a higher induction ability than IFN-γ rel in relation with the expression of IRF1. IFN-γ stimulated the expression level of STAT1a and also STAT1b, but they had opposite trends with the increase of time; enhancement of STAT1a waned after 12 h post injection of plasmids; whereas STAT1b expression increased continuously. Zebrafish IRF1 gene promoter contained several putative transcription factor binding sites, including GAS and NF-κB motifs. Luciferase assay revealed that the GAS site was essential in the IFN-γ triggered IRF1 expression. In contrast, IRF11 contained neither GAS nor NF-κB elements, and did not respond to IFN-γ induction. It is considered that STAT1a and STAT1b are structurally and functionally similar to STAT1α and STAT1β in mammal respectively, and that IRF11, although used to be nominated as IRF1a, is not the orthologue of mammalian IRF1, but IRF1b in zebrafish should be the orthologue.

Abstract
Vaccine development against extracellular bacteria has been important for the sustainability of the aquaculture industry. In contrast, infections with intracellular pathogens remain largely an unresolved problem. Francisella noatunensis subsp. orientalis is a Gram-negative, facultative intracellular bacterium that causes the disease francisellosis in fish. Francisellosis is commonly characterized as a chronic granulomatous disease with high morbidity and can result in high mortality depending on the host. In this study, we explored the potential of bacterial membrane vesicles (MVs) as a vaccine agent against F. noatunensis subsp. orientalis. Bacterial MVs are spherical structures naturally released from the membrane of bacteria and are often enriched with selected bacterial components such as toxins and signaling molecules. MVs were isolated from broth-cultured F. noatunensis subsp. orientalis in the present work, and proteomic analysis by mass spectrometry revealed that MVs contained a variety of immunogenic factors, including the intracellular growth proteins IglC and IglB, known to be part of a Francisella pathogenicity island (FPI), as well as outer membrane protein OmpA, chaperonin GroEL, and chaperone ClpB. By using flow cytometry and electron microscopy, we observed that F. noatunensis subsp. orientalis mainly infects myelomonocytic cells, both in vivo and in vitro. Immunization with MVs isolated from F. noatunensis subsp. orientalis protects zebrafish from subsequent challenge with a lethal dose of F. noatunensis subsp. orientalis. To determine if MVs induce a typical acute inflammatory response, mRNA expression levels were assessed by quantitative real-time PCR. Expression of tnfa, il1b, and ifng, as well as mhcii, mpeg1.1, and ighm, was upregulated, thus confirming the immunogenic properties of F. noatunensis subsp. orientalis-derived MVs.

Abstract
The earliest jawed vertebrates (Gnathostomes) would likely have had interferon (IFN) genes, since they are present in extant cartilaginous fish (sharks and rays) and bony fish (lobe-finned and ray-finned fish, the latter consisting of the chondrostei, holostei, and teleostei), as well as in tetrapods. They are thought to have evolved from a class II helical cytokine ancestor, along with the interleukin (IL)-10 cytokine family. The two rounds of whole genome duplication (WGD) that occurred between invertebrates and vertebrates (1) may have given rise to additional loci, initially containing an IL-10 ancestor and IFN ancestor, which have duplicated further to give rise to the two loci containing the IL-10 family genes, and potentially the IFN type I and IFN type III loci (2). The timing of the divergence of the IFN type II gene from the IL-10 family genes is not clear but was also an early event in vertebrate evolution. Further WGD events at the base of the teleost fish, and in particular teleost lineages (cyprinids, salmonids), have duplicated the loci further, giving rise to additional IFN genes, with tandem gene duplication within a locus a common occurrence. Finally, retrotransposition events have occurred in different vertebrate lineages giving rise to further IFN loci, with large expansions of genes at these loci in some cases. This review will initially explore the likely IFN system present in the earliest Gnathostomes by comparison of the known cartilaginous fish genes with those present in mammals and will then explore the changes that have occurred in gene number/diversification, gene organization, and the encoded proteins during vertebrate evolution.

Abstract
Arsenic poisoning is a serious global issue. Apart from causing developmental and systemic toxicity, arsenic has recently been reported for its ability to hinder immune responses. The present study is designed to identify the global expression profile associated with arsenic-induced immune alterations at the organismic level. Adult zebrafish (Danio rerio) were exposed to 20, 40 and 80ppb of arsenic trioxide for 30days, sacrificed and global gene expression profile studied. Microarray data suggested 65 immune related genes were commonly affected in the three treatment regimens. The expression profile of key immune related genes (tlr1, nitr1f, nitr1c, crfb8, socs7, socs3b, abcb3/1, mch1uja, ifnγ1-2, cxcl12b and crlf1a) was validated by qPCR. Pathway analysis suggested the major involvement of JAK-STAT circuit in the process. The expression of these marker genes was also studied in arsenic exposed and bacteria (Aeromonas hydrophila) challenged zebrafish. Increase in bacterial colony forming units (CFU) coupled with gross histopathology of kidney in arsenic exposed-bacteria challenged fish suggested profound immuno-compromised condition. We propose that chronic arsenic exposure leads to hyperactivation of the immune system as a consequence when exposed to further stress (microbial) it induces immuno-suppression with pathological implications. The study provides a molecular snap shot for predicting arsenic immuno-toxicity.

Abstract
Pattern recognition receptors (PRRs) and their signaling pathways have essential roles in recognizing various components of pathogens as well as damaged cells and triggering inflammatory responses that eliminate invading microorganisms and damaged cells. The zebrafish relies heavily on these primary defense mechanisms against pathogens. Here, we review the major PRR signaling pathways in the zebrafish innate immune system and compare these signaling pathways in zebrafish and humans to reveal their evolutionary relationship and better understand their innate immune defense mechanisms.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2016; 63:1-9.

Abstract
The interferon (IFN) regulatory factor 3 (IRF3) is a member of the IFN regulatory transcription factor family, which binds to the IFN-stimulated response element (ISRE) within the promoter of IFN genes and IFN-stimulated genes. In this study, the IRF3 cDNA of sea perch Lateolabrax maculatus (SpIRF3) was identified, which contained 1781 bp with an open reading frame of 1398 bp that coded a 465 amino acid protein. The SpIRF3 protein shared conserved characterizations with its homologues and displayed the conserved DNA-binding domain, IRF association domain, serine-rich C-terminal domain, and tryptophan residue cluster. Phylogenetic analysis illustrated that SpIRF3 belonged to the IRF3 subfamily. Subcellular localization analysis showed that SpIRF3 mainly resided in the cytoplasm without stimuli but translocated into nuclei in the presence of poly I:C. Real-time PCR data indicated that SpIRF3 was transcriptionally up-regulated by poly I:C stimulation in various organs. Moreover, reporter assay revealed that SpIRF3 functioned as a modulator in triggering the IFN response by inducing the activity of IFN and ISRE-containing promoter. These data revealed that SpIRF3 was a potential molecule in the IFN immune defense system against viral infection.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2016; 62:108-115. [PMID: 27156851 DOI: 10.1016/j.dci.2016.04.021] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/11/2016] [Revised: 04/29/2016] [Accepted: 04/29/2016] [Indexed: 06/05/2023]
Abstract
In vertebrates, the rejection of allografts is primarily accomplished by cell-mediated immunity. We recently identified four IFNγ isoforms with antiviral activity in ginbuna crucian carp, Carassius auratus langsdorfii. However, involvement of the IFNγ isoforms in cell-mediated immunity, especially in T cell function remains unknown. Here we investigate expression of the IFNγ isoforms and effects of administration of recombinant IFNγ (rgIFNγ) isoforms in ginbuna scale allograft rejection. All four IFNγ isoforms showed significantly higher expression with the progression of graft rejection. Administration of rgIFNγrel 1 but not rgIFNγrel 2, rgIFNγ1 nor rgIFNγ2 enhanced allograft rejection. The number of CD4(+) and CD8α(+) cells increased in early stages of rejection, while sIgM(+) cells were higher than controls at day 0 and 5 in the rgIFNγrel 1 administrated group. Expression of IFNγ1 and IFNγ2 mRNA was significantly up-regulated by rgIFNγrel 1 administration, while that of IFNγrel 1 and IFNγrel 2 was not. These results suggest different contributions of the four IFNγ isoforms toward the immune responses comprising allograft rejection.
