Int J Mol Sci 2024; 25:6438. [PMID: 38928143 PMCID: PMC11204273 DOI: 10.3390/ijms25126438] [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: 03/07/2024] [Revised: 06/05/2024] [Accepted: 06/05/2024] [Indexed: 06/28/2024] Open
Abstract
Grass Carp Reovirus (GCRV) and Aeromonas hydrophila (Ah) are the causative agents of haemorrhagic disease in grass carp. This study aimed to investigate the molecular mechanisms and immune responses at the miRNA, mRNA, and protein levels in grass carp kidney cells (CIK) infected by Grass Carp Reovirus (GCRV, NV) and Aeromonas hydrophilus (Bacteria, NB) to gain insight into their pathogenesis. Within 48 h of infection with Grass Carp Reovirus (GCRV), 99 differentially expressed microRNA (DEMs), 2132 differentially expressed genes (DEGs), and 627 differentially expressed proteins (DEPs) were identified by sequencing; a total of 92 DEMs, 3162 DEGs, and 712 DEPs were identified within 48 h of infection with Aeromonas hydrophila. It is worth noting that most of the DEGs in the NV group were primarily involved in cellular processes, while most of the DEGs in the NB group were associated with metabolic pathways based on KEGG enrichment analysis. This study revealed that the mechanism of a grass carp haemorrhage caused by GCRV infection differs from that caused by the Aeromonas hydrophila infection. An important miRNA-mRNA-protein regulatory network was established based on comprehensive transcriptome and proteome analysis. Furthermore, 14 DEGs and 6 DEMs were randomly selected for the verification of RNA/small RNA-seq data by RT-qPCR. Our study not only contributes to the understanding of the pathogenesis of grass carp CIK cells infected with GCRV and Aeromonas hydrophila, but also serves as a significant reference value for other aquatic animal haemorrhagic diseases.

Abstract
The mammalian sterile 20-like (MST) family belongs to the serine/threonine protein kinase (STK) superfamily and participates in a variety of biological processes, such as cell apoptosis, polarity, migration, immune regulation, inflammatory responses, and cancer. In the economically important bighead carp (Hypophthalmichthys nobilis), the STK gene family and immune-related biological functions may be helpful in increasing its economic yield. However, the comprehensive role of STKs in the bighead carp remains unclear. In this study, the five stk sequences from the bighead carp were divided into two classes: stk3/4 and stk24/25/26. Gene structure and motif prediction analyses confirmed that stk is conserved in the bighead carp. Compared to 26 other vertebrate species, teleosts (including bighead carp) possess more stk members because of teleost-specific whole-genome duplication. Synteny analysis revealed that stk3, stk24, stk25, and stk26 have been relatively conserved in bighead carp during evolution. Meanwhile, stk4 was lost in most Cyprinid species, including bighead carp, during evolution. RNA-seq data revealed that STK expression was associated with various pathogens, and the expression of these STKs (Hnstk3, Hnstk24a, Hnstk24b, Hnstk25, and Hnstk26) was different in seven tissues of bighead carp. In addition, we showed that STK expression levels were dramatically altered in the head kidney and that stk24 was involved in defense against Aeromonas hydrophila. This study provides a molecular basis for the analysis of stk function in bighead carp, and can be used as a reference for further phylogenomics.

Abstract
Hirame novirhabdovirus (HIRRV) is a fish rhabdovirus belonging to family Rhabdoviridae, genus Novirhabdovirus, which is highly contagious and virulent, and causes hemorrhagic disease in many fish species. In the present work, the whole genome sequence of HIRRV strain CNPo2015 that previously isolated from cultured flounders was obtained using high-throughput sequencing. It consists of 10,998 nucleotides and encodes six viral proteins arranged in order of 3'-N-P-M-G-NV-L-5'. Among Novirhabdovirus, L protein of CNPo2015 possessed the lowest amino acid sequence divergence with HIRRV isolate CA 9703 and HIRRV 080113, and the highest with Snakehead rhabdovirus. Furthermore, the immune response of Hirame natural embryo (HINAE) cell line to HIRRV infection was characterized by RNA-seq, and the results showed that 1976 differentially expressed genes (DEGs) including 1219 up-regulated and 727 down-regulated genes were identified in the HINAE cells infected with HIRRV at 48 h post infection (hpi). Several KEGG pathways were significantly enriched in the viral infected cells, such as cytokine-cytokine receptor interaction, JAK-STAT signaling pathway, cell cycle, apoptosis, RIG-I-like receptors signaling pathway and P13K-AKT signaling pathway. Post viral infection, the flow cytometric Annexin V/PI assay found that apoptotic rate of HINAE cells showed a slight increase within 3 days and then the early and late apoptotic rate were significantly increased to 41 ± 2.65% and 12.37 ± 2.61% at day 4, respectively. Meanwhile, qRT-PCR results also showed that six apoptosis-related genes (BCL2L1, CASPASE 3, CASPASE 10, FAS, AKT and CDK1) were significantly upregulated. This investigation has not only enriched our knowledge of sequence difference characteristics between CNPo2015 and other Novirhabdoviruses, but also provided a data basis for deeper understanding of immune responses in flounder cells post viral infection.

Abstract
Economic importance of common carp (Cyprinus carpio L.) increases every year. Viral diseases are major threat for carp aquaculture and cause significant economic losses. Koi herpesvirus (KHV) is one of the most serious carp diseases. Current study is focused on confirmation of possible differences in early immune response to KHV depending on level of resistance. Class I interferon signalling, complement cascade and cell-mediated cytotoxicity are hypothesized as major mechanisms of early innate immune response against KHV. Different breeds of common carp show distinct level of resistance to KHV. Two breeds of common carp with completely different susceptibility to KHV were chosen for current research: amur wild carp (AS) as highly resistant and koi carp (KOI) as very susceptible breed. KHV infection caused no mortalities, but the viral load in selected tissues increased during infection. Levels of expressions of chosen genes was examined using qRT-PCR and overall change in protein expression profiles was analysed by mass spectrometry. Significant differences in immune response between AS and KOI were detected mostly at the level of protein expression. Although cell-mediated cytotoxicity showed minimal influence during KHV infection, many immune response parameters related to class I interferon signalling pathway and complement cascade were increased earlier during KHV infection in AS comparing to KOI.

Abstract
Fish skin is an essential protective barrier and functions as the first line of immune defense against pathogens. However, the molecular mechanism at the proteome-level remains unclear in the skin of fish. In this study, the comparative proteomics of skin immune responses of crucian carp Carassius auratus infected with Aeromonas hydrophila was investigated by isobaric tags for relative and absolute quantification (iTRAQ), two-dimensional gel electrophoresis combined with mass spectrometry (2-DE/MS) as well as high-throughput transcriptome (RNA-seq) techniques. A total of 241 and 178 differentially expressed proteins (DEPs) at 6 and 12 h post-infection (hpi) were respectively identified by iTRAQ, and key-DEPs were furtherly verified with 2-DE/MS analysis. GO and KEGG analysis showed that these DEPs were mostly related to metabolism, regulation of the cytoskeleton, stress and immune responses. Co-association results of proteome and transcriptome revealed the lysozyme (LYZ), complement C3, DnaJ (Hsp40) homolog subfamily C member 8 (DNAJC8) and allograft inflammatory factor 1-like (AIF1L) play important roles in skin immune responses of crucian carp. The significantly up-regulated expression of detected immune-related genes (c3, mapk3, f5, nlr, hsp90, itgb2, fnl, flnca, p47, mhc and pros1) were validated by qRT-PCR analysis. To our knowledge, this is first report on multi-omics analysis of the differential proteomics for the skin immune response of C. auratus against A.hydrophila infection, which contribute to the understanding the mechanisms of skin mucosal immunity in cyprinid fish.

Abstract
Zebrafish are increasingly being utilized as a model to investigate infectious diseases and to advance the understanding of pathogen–host interactions. Here, we take advantage of the zebrafish to recapitulate congenital ZIKV infection and, for the first time, demonstrate that it can be used to model infection and reinfection and monitor anti-viral and inflammatory immune responses, as well as brain growth and eye abnormalities during embryonic development. By injecting a Brazilian strain of ZIKV into the yolk sac of one-cell stage embryos, we confirmed that, after 72 h, ZIKV successfully infected larvae, and the physical condition of the virus-infected hosts included gross morphological changes in surviving embryos (84%), with a reduction in larval head size and retinal damage characterized by increased thickness of the lens and inner nuclear layer. Changes in locomotor activity and the inability to perceive visual stimuli are a result of changes in retinal morphology caused by ZIKV. Furthermore, we demonstrated the ability of ZIKV to replicate in zebrafish larvae and infect new healthy larvae, impairing their visual and neurological functions. These data reinforce the deleterious activity of ZIKV in the brain and visual structures and establish the zebrafish as a model to study the molecular mechanisms involved in the pathology of the virus.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2021; 123:104163.

Abstract
α-Enolase is an enzyme of the glycolytic pathway that has also been involved in vertebrate inflammatory processes through its interaction with plasminogen. However, its participation in the immune response of lower vertebrates during early life development is unknown. Opportunistic pathogens in salmon farming are the principal cause of mortality in the fry stage. For that reason, molecular indicators of their immunological status are required to ensure the success of the large-scale cultivation. Thus, the objective of this work was to analyze if ENO-1 is involved in the immune response of rainbow trout fry. For this purpose, the coding sequence of trout ENO-1 was characterized, identifying the plasminogen-binding domain that has been described for homologs of this enzyme in higher vertebrates. A peptide-epitope of α-enolase was used for producing mice antiserum. The specificity of polyclonal antibodies was confirmed by dot blot, ELISA and Western blot. Then, the antiserum was used to evaluate α-enolase expression in fry between 152 and 264 degree-days post-hatching after 2, 8, and 12 h of challenge with lipopolysaccharide from Pseudomona auroginosa. The expression of α-enolase at both transcriptional (RT-qPCR) and protein (ELISA) levels was significantly increased after 8 h post-challenge with lipopolysaccharide. These results were confirmed by proteomic analysis by 2D-difference gel electrophoresis (DIGE). This work provides the first evidence of the involvement of α-enolase in the early immune response of salmonids. Future research will be required to understand the possible interaction of α-enolase with plasminogen in cells and tissues of the salmonid immune system.

Abstract
Novirhabdoviruses belong to the Rhabdoviridae family of RNA viruses. All of the four members are pathogenic for bony fish. Particularly, Infectious hematopoietic necrosis virus (IHNV) and Viral hemorrhagic septicemia virus (VHSV) often cause mass animal deaths and huge economic losses, representing major obstacles to fish farming industry worldwide. The interactions between fish and novirhabdoviruses are becoming better understood. In this review, we will present our current knowledge of fish innate immunity, particularly type I interferon (IFN-I) response, against novirhabdoviral infection, and the evasion strategies exploited by novirhabdoviruses. Members of Toll-like receptors (TLRs) and RIG-I-like receptors (RLRs) appear to be involved in novirhabdovirus surveillance. NF-κB activation and IFN-I induction are primarily triggered for antiviral defense. Autophagy can also be induced by viral glycoprotein (G). Although sensitive to IFN-I, novirhabdoviruses have nucleoprotein (N), matrix protein (M), and non-virion protein (NV) to interfere with host signal transduction and gene expression steps toward antiviral state establishment. Moreover, novirhabdoviruses may exploit some microRNAs for immunosuppression.

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
Viral hemorrhagic septicemia virus (VHSV) is a rhabdovirus reported to cause economic loss in fish farms. Because of the lack of adequate preventative treatments, the identification of multipath genes involved in VHS infection might be an alternative to explore the possibility of using drugs for the seasonal prevention of this fish disease. We propose labeling a category of drug molecules by further classification and interpretation of the Drug Gene Interaction Database using gene ontology and Kyoto Encyclopedia of Genes and Genomes enrichment scores. The study investigated disease networks of up-and down-regulated genes to find those with high interaction as substantial genes in pathways among the different disease networks. We prioritized these genes based on their relationship to those associated with VHS infection in the context of human protein-protein interaction networks and disease pathways. Among the 29 genes as potential drug targets, nine were selected as promising druggable genes (ERBB2, FGFR3, ITGA2B, MAP2K1, NGF, NTRK1, PDGFRA, SCN2B, and SERPINC1). PDGFRA is the most important druggable up-and down-regulated gene and is considered an important gene in the IMATINIB pathway. This study findings indicate a promising approach for drug target prediction for VHS treatment, which might be useful for disease therapeutics.

Abstract
One of the main constraints in aquaculture production is farmed fish vulnerability to diseases due to husbandry practices or external factors like pollution, climate changes, or even the alterations in the dynamic of product transactions in this industry. It is though important to better understand and characterize the intervenients in the process of a disease outbreak as these lead to huge economical losses in aquaculture industries. High-throughput technologies like proteomics can be an important characterization tool especially in pathogen identification and the virulence mechanisms related to host-pathogen interactions on disease research and diagnostics that will help to control, prevent, and treat diseases in farmed fish. Proteomics important role is also maximized by its holistic approach to understanding pathogenesis processes and fish responses to external factors like stress or temperature making it one of the most promising tools for fish pathology research.

Abstract
The ninth complement component (C9) is a terminal complement component (TCC) that is involved in creating the membrane attack complex (MAC) on the target cell surface. In this study, the CsC9 (C9 of Cynoglossus semilaevis) cDNA sequence was cloned and characterized. The full-length CsC9 cDNA measured 2,150 bp, containing an open reading frame (ORF) of 1,803 bp, a 5'-untranslated region (UTR) of 24 bp and a 3'-UTR of 323 bp. A domain search revealed that the CsC9 protein contains five domains, including two TSP1s, an LDLRA, an EGF, and a MACPF. Quantitative real-time PCR analysis showed that CsC9 at the mRNA level was expressed in all the tested tissues, with the highest expression being observed in the liver. CsC9 expression is significantly upregulated in the tested tissues after challenge with Vibrio anguillarum. To further characterize the role of CsC9, peripheral blood mononuclear cells of C. semilaevis were used for transcriptome analysis after incubation with recombinant CsC9 (rCsC9) protein. A total of 3,775 significant differentially expressed genes (DEGs) were identified between the control and the rCsC9-treated group, including 2,063 upregulated genes and 1,712 downregulated genes. KEGG analyses revealed that the DEGs were enriched in cell adhesion molecules, cytokine-cytokine receptor interactions, T cell receptor signaling pathways, B cell receptor signaling pathways and Toll-like receptor signaling pathways. The results of this study indicate that in addition to participating in MAC formation, CsC9 might play multiple roles in the innate and adaptive immunity of C. semilaevis.

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
C8α and C9 mediate the membrane attack complex formation and bacterial lysis and are important components in the complement system. The cDNA sequences of the C8α and C9 genes were cloned from Takifugu rubripes. The full-length cDNA of Tr-C8α was 1893 bp and included a 5'-UTR of 69 bp and 3'-UTR of 83 bp. The full-length cDNA of Tr-C9 was 2083 bp and included a 5'-UTR of 72 bp and 3'-UTR of 250 bp. The expression of Tr-C8α and Tr-C9 was detected in newly fertilized eggs of T. rubripes. The expression of these two genes was at a higher level in the liver than in other tissues tested. After lipopolysaccharide (LPS) challenge, the gene expression of Tr-C8α and Tr-C9 increased more significantly in the liver. With these combined results, we further understood how Tr-C8α and Tr-C9 function in the innate immunity of pufferfish. Our findings could deepen the understanding of immune regulation in pufferfish.

Abstract
Spring viremia of carp virus (SVCV) causes the skin hemorrhagic disease in cyprinid species, but its molecular mechanism of skin immune response remains unclear at the protein level. In the present study, the differential proteomics of the zebrafish (Danio rerio) skin in response to SVCV infection were examined by isobaric tags for relative and absolute quantitation and quantitative polymerase chain reaction (qPCR) assays. A total of 3999 proteins were identified, of which 320 and 181 proteins were differentially expressed at 24 and 96 h postinfection, respectively. The expression levels of 16 selected immune-related differentially expressed proteins (DEPs) were confirmed by qPCR analysis. Furthermore, Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses revealed that DEPs were significantly associated with complement, inflammation, and antiviral response. The protein-protein interaction network of cytoskeleton-associated proteins, ATPase-related proteins, and parvalbumins from DEPs was shown to be involved in skin immune response. This is first report on the skin proteome profiling of zebrafish against SVCV infection, which will contribute to understand the molecular mechanism of local mucosal immunity in fish.

Abstract
Seasonal temperature has a major influence on the infectivity of pathogens and the host immune system. Viral hemorrhagic septicemia virus (VHSV) is one such pathogen that only causes the mortality of fish at low temperatures. This study aims to discover the host defense mechanism and pathway for resistance to VHSV at higher temperatures. We first observed the VHSV infection patterns at low and higher temperatures in fathead minnow (FHM) cells (20 °C and 28 °C) and zebrafish (15 °C and 25 °C). In comparison to the 20 °C infection, FHM cells infected at 28 °C showed decreased apoptosis, increased cell viability, and reduced VHSV N gene expression. In zebrafish, infection at 25 °C caused no mortality and significantly reduced the N gene copy number in comparison to infection at 15 °C. To explore the antiviral infection mechanisms induced by high temperature in vitro and in vivo, the changes in the proteomic profile were measured through UPLC-MSE analysis. ACADL, PTPN6, TLR1, F7, A2M, and GLI2 were selected as high temperature-specific biomarkers in the FHM cell proteome; and MYH9, HPX, ANTXR1, APOA1, HBZ, and MYH7 were selected in zebrafish. Increased immune response, anticoagulation effects, and the formation of lymphocytes from hematopoietic stem cells were analyzed as functions that were commonly induced by high temperature in vitro and in vivo. Among these biomarkers, GLI2 was predicted as an upstream regulator. When treated with GANT58, a GLI-specific inhibitor, cell viability was further reduced due to GLI2 inhibition during VHSV infection at varying temperatures in FHM cells, and the mortality in zebrafish was induced earlier at the low temperature. Overall, this study discovered a new mechanism for VHSV infection in vitro and in vivo that is regulated by GLI2 protein.

Abstract
To better understand spring viremia of carp virus (SVCV) pathogenesis in zebrafish proteomic analysis was used to examine the plasma protein profile in SVCV-infected zebrafish. A total of 3062 proteins were identified. Of those 137, 63 and 31 proteins were enriched in blood samples harvested at 1, 2 and 5 days post SVCV infection, respectively. These altered host proteins were classified based on their biological function: 23 proteins under the response to stimulus term were identified. Interestingly, at the top of the up-regulated proteins during SVCV infection were the proteins of the vitellogenin family (Vtg) and the grass carp reovirus-induced gene (Gig) proteins. Real-time RT-PCR evaluation of samples from internal organs verified that SVCV infection induced vtg and gig2 gene expression already at day 1 post-infection. Western blot analysis revealed the presence of Vtg protein only in blood of SVCV-infected fish. This is the first proteomic study to reveal the involvement of Vtg proteins in adult fish response to viral challenge. It also highlights the role of Gig proteins as important factors in antiviral response in fish. This work provides valuable relevant insight into virus-host interaction and the identification of molecular markers of fish response to virus.

Abstract
Chromatin immunoprecipitation (ChIP) and high throughput sequencing (ChIP-seq) have been used to assess histone methylation (epigenetic modification) dynamics within the internal organs of zebrafish after spring viremia of carp virus (SVCV) infection. Our results show H3K4me3 up-methylation in gene promoters associated with innate immune response during the first 5 days after SVCV infection. Gene Ontology (GO) enrichment analysis confirmed up-methylation in 218 genes in the "immune system process" category. In particular, the promoters of interferon (ifn), interferon stimulated genes (isg), Toll-like receptors (tlr) and c-reactive protein (crp) multi gene sets were marked with the permissive H3K4 methylation. Higher histone 3 methylation was associated with higher transcription levels of the corresponding genes. Therefore, the evidence presented here suggests that transcriptional regulation at the promoter level of key immune genes of the interferon signaling pathway and c-reactive proteins genes can be modulated by epigenetic modification of histones. This study emphasizes the importance of epigenetic control in the response of zebrafish to SVCV infection.

FISH & SHELLFISH IMMUNOLOGY 2018; 82:386-399. [PMID: 30071344 DOI: 10.1016/j.fsi.2018.07.057] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/14/2018] [Revised: 05/10/2018] [Accepted: 07/28/2018] [Indexed: 06/08/2023]
Abstract
Cyprinid herpesvirus 2 (CyHV-2) is a pathogen of herpesviral hematopoietic necrosis disease of crucian carp. Our study aimed to investigate the molecular mechanisms and immune response at the mRNA and protein levels in head kidney during CyHV-2 infection. Three days after infection with CyHV-2, 7085 differentially expressed genes were identified by transcriptome sequencing, of which 3090 were up-regulated and 3995 were down-regulated. And 338 differentially expressed proteins including 277 up-regulated and 61 down-regulated were identified using tandem mass tag labeling followed by liquid chromatography tandem mass spectrometry. Notably, 128 differentially co-expressed genes at mRNA and protein levels (cDEGs) were reliably quantified, including 86 co-up-regulated and 42 co-down-regulated. In addition, 10 cDGEs in the above pathways were selected for qRT-PCR to confirm the validity of the transcriptome and proteome changes by showing that RIG-I, MDA5, LGP2, FAS, PKR and PKZ up-regulated and Integrin α, Integrin β2, NCF2 and NCF4 down-regulated. This indicated that after CyHV-2 infection, the herpes simplex infection pathway, RIG-I like receptor signaling pathway, necroptosis pathway and p53 signaling pathway were activated and the phagosome pathway was suppressed. Our findings reveal the pathogenesis and the host immune mechanism of CyHV-2 infection of crucian carp.

Abstract
CD36 is a scavenger receptor, a type of membrane-bound receptors that characterized by recognizing a variety of ligands including endogenous proteins and pathogens. Here, we characterized CD36 gene in turbot, and its expression patterns in mucosal barriers following different bacterial infection, as well as microbial ligand binding ability and bacteriostatic activities. In current study, one SmCD36 gene was captured with a 1407 bp open reading frame (ORF). In multiple species comparison, SmCD36 showed the highest similarity and identity to Cynoglossus semilaevis. In the phylogenetic analysis, SmCD36 showed the closest relationship to C. semilaevis, followed by Takifugu rubripes. The genomic structure analysis showed that CD36 had 12 exons with almost the same length in vertebrate species, indicating the conservation of CD36 during evolution. The syntenic analysis revealed that CD36 located between GNAI1 and SEMA3C genes across all the selected species, which suggested the synteny encompassing CD36 region during vertebrate evolution. Subsequently, SmCD36 was expressed in all the examined turbot tissues, with the highest expression level in intestine. In addition, SmCD36 was significantly up-regulated in intestine following both Gram-negative bacteria Vibrio anguillarum, and Gram-positive bacteria Streptococcus iniae immersion challenge. Finally, the rSmCD36 showed strong binding ability to all the examined microbial ligands and significant inhibition effect on Staphylococcus aureusrequires. Taken together, our results suggested SmCD36 involved in fish innate immune responses to bacterial infection. However, the knowledge of CD36 are still limited in teleost species, further studies should be carried out to better characterize its detailed roles in teleost mucosal immunity.

Abstract
Yersinia ruckeri is the causative agent of enteric redmouth disease in salmonids. Head kidney and spleen are major lymphoid organs of the teleost fish where antigen presentation and immune defense against microbes take place. We investigated proteome alteration in head kidney and spleen of the rainbow trout following Y. ruckeri strains infection. Organs were analyzed after 3, 9 and 28 days post exposure with a shotgun proteomic approach. GO annotation and protein-protein interaction were predicted using bioinformatic tools. Thirty four proteins from head kidney and 85 proteins from spleen were found to be differentially expressed in rainbow trout during the Y. ruckeri infection process. These included lysosomal, antioxidant, metalloproteinase, cytoskeleton, tetraspanin, cathepsin B and c-type lectin receptor proteins. The findings of this study regarding the immune response at the protein level offer new insight into the systemic response to Y. ruckeri infection in rainbow trout. This proteomic data facilitate a better understanding of host-pathogen interactions and response of fish against Y. ruckeri biotype 1 and 2 strains. Protein-protein interaction analysis predicts carbon metabolism, ribosome and phagosome pathways in spleen of infected fish, which might be useful in understanding biological processes and further studies in the direction of pathways.

Genetic and transcriptomic analyses provide new insights on the early antiviral response to VHSV in resistant and susceptible rainbow trout. BMC Genomics 2018; 19:482. [PMID: 29921219 PMCID: PMC6009034 DOI: 10.1186/s12864-018-4860-1] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2018] [Accepted: 06/11/2018] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND The viral hemorrhagic septicemia virus (VHSV) is a major threat for salmonid farming and for wild fish populations worldwide. Previous studies have highlighted the importance of innate factors regulated by a major quantitative trait locus (QTL) for the natural resistance to waterborne VHSV infection in rainbow trout. The aim of this study was to analyze the early transcriptomic response to VHSV inoculation in cell lines derived from previously described resistant and susceptible homozygous isogenic lines of rainbow trout to obtain insights into the molecular mechanisms responsible for the resistance to the viral infection. RESULTS We first confirmed the presence of the major QTL in a backcross involving a highly resistant fish isogenic line (B57) and a highly susceptible one (A22), and were able to define the confidence interval of the QTL and to identify its precise position. We extended the definition of the QTL since it controls not only resistance to waterborne infection but also the kinetics of mortality after intra-peritoneal injection. Deep sequencing of the transcriptome of B57 and A22 derived cell lines exposed to inactivated VHSV showed a stronger response to virus inoculation in the resistant background. In line with our previous observations, an early and strong induction of interferon and interferon-stimulated genes was correlated with the resistance to VHSV, highlighting the major role of innate immune factors in natural trout resistance to the virus. Interestingly, major factors of the antiviral innate immunity were much more expressed in naive B57 cells compared to naive A22 cells, which likely contributes to the ability of B57 to mount a fast antiviral response after viral infection. These observations were further extended by the identification of several innate immune-related genes localized close to the QTL area on the rainbow trout genome. CONCLUSIONS Taken together, our results improve our knowledge in virus-host interactions in vertebrates and provide novel insights in the molecular mechanisms explaining the resistance to VHSV in rainbow trout. Our data also provide a collection of potential markers for resistance and susceptibility of rainbow trout to VHSV infection.

Abstract
With the development of intensive aquaculture, economic losses increasingly result from fish mortality due to pathogen infection. In recent years, a growing number of researchers have used transcriptomic and proteomic analyses to study fish immune responses to exogenous pathogen infection. Integrating transcriptomic and proteomic analyses provides a better understanding of the fish immune system including gene expression, regulation, and the intricate biological processes underlying immune responses against infection. This review focuses on the recent advances in the fields of transcriptomics and proteomics, which have contributed to our understanding of fish immunity to exogenous pathogens.

Abstract
Ichthyophthirius multifiliis is a ciliated protozoan parasite recognized as one of the most pathogenic diseases of wild and cultured freshwater fish. Fish skin mucus plays a significant role against invading pathogens. However, the protein-based modulation against infection with I. multifiliis, of host fish at this barrier is unknown. Thus, we investigated the skin mucus proteome of common carp using a shotgun proteomic approach at days 1 and 9 after I. multifiliis exposure. We identified 25 differentially expressed proteins in infected carp skin mucus. Upregulated proteins were mainly involved in metabolism, whereas downregulated proteins were mainly structural. This is the first proteomic analysis of infected common carp skin mucus, and it provides novel information about proteome alteration caused by I. multifiliis. Furthermore, we identified novel proteins with yet unknown function in common carp following penetrating injuries such as olfactomedin 4, lumican, dermatopontin, papilin and I cytoskeletal 18. This analysis, therefore, represents a key for the search for potential biomarkers, which can help in a better understanding and monitoring of interactions between carp and I. multifiliis. This proteomic study not only provides information on the protein-level pathways involved in fish-ciliate interactions but also could represent a complementary system for studying tissue repair.

Abstract
Recently in 2016, the European Medicines Agency (EMA) recommended granting a marketing authorization in the EU for "Clynav," a DNA vaccine against salmon pancreas disease (salmonid alphavirus-3). Generally, DNA vaccines induce both early and late immune responses in fish that may be protective against disease. Several transcriptomic approaches have been performed to map immunome profiles following DNA vaccination, but the precise immune mechanism(s) that is responsible for protection is not known, although reasonable suggestions have been made. The current review includes an overview on main transcriptomic findings from microarray experiments after DNA vaccination against VHSV, IHNV, HIRRV and IPNV-with considerations of what can be considered as correlates of protection (CoP) or merely a surrogate of protection. Identification and use of correlates of protection (COPs) may be a strategic tool for accelerated and targeted vaccine design, testing and licensure. General rules on what can be considered as CoPs can be extracted from past knowledge on protective immune responses following vaccination that induced protection. Lastly, there will be an overview on non-viral molecular adjuvants that have been exploited to obtain higher vaccine potencies and efficacies.

Abstract
The mucosal immune system of fish is a complex network of immune cells and molecules that are constantly surveilling the environment and protecting the host from infection. A number of "omics" tools are now available and utilized to understand the complexity of mucosal immune systems in non-traditional animal models. This review summarizes recent advances in the implementation of "omics" tools pertaining to the four mucosa-associated lymphoid tissues in teleosts. Genomics, transcriptomics, proteomics, and "omics" in microbiome research require interdisciplinary collaboration and careful experimental design. The data-rich datasets generated are proving really useful at discovering new innate immune players in fish mucosal secretions, identifying novel markers of specific mucosal immune responses, unraveling the diversity of the B and T cell repertoires and characterizing the diversity of the microbial communities present in teleost mucosal surfaces. Bioinformatics, data analysis and storage platforms should be developed to facilitate rapid processing of large datasets, especially when mammalian tools such as bioinformatics analysis software are not available in fishes.

Abstract
This work explores the unexpected in vivo and in vitro anti-viral functions of the seven c-reactive protein (crp1-7) genes of zebrafish (Danio rerio). First results showed heterogeneous crp1-7 transcript levels in healthy wild-type zebrafish tissues and organs and how those levels heterogeneously changed not only after bacterial but also after viral infections, including those in adaptive immunity-deficient rag1-/- mutants. As shown by microarray hybridization and proteomic techniques, crp2/CRP2 and crp5/CRP5 transcripts/proteins were among the most modulated during in vivo viral infection situations including the highest responses in the absence of adaptive immunity. In contrast crp1/CRP1/and crp7/CRP7 very often remained unmodulated. All evidences suggested that zebrafish crp2-6/CRP2-6 may have in vivo anti-viral activities in addition to their well known anti-bacterial and/or physiological functions in mammalians. Confirming those expectations, in vitro neutralization and in vivo protection against spring viremia carp virus (SVCV) infections were demonstrated by crp2-6/CRP2-6 using crp1-7 transfected and/or CRP1-7-enriched supernatant-treated fish cells and crp2-5-injected one-cell stage embryo eggs, respectively. All these findings discovered a crp1-7/CRP1-7 primitive anti-viral functional diversity.These findings may help to study similar functions on the one-gene-coded human CRP, which is widely used as a clinical biomarker for bacterial infections, tissue inflammation and coronary heart diseases.

Abstract
Background Gibel carp is an important aquaculture species in China, and a herpesvirus, called as Carassius auratus herpesvirus (CaHV), has hampered the aquaculture development. Diverse gynogenetic clones of gibel carp have been identified or created, and some of them have been used as aquaculture varieties, but their resistances to herpesvirus and the underlying mechanism remain unknown. Results To reveal their susceptibility differences, we firstly performed herpesvirus challenge experiments in three gynogenetic clones of gibel carp, including the leading variety clone A+, candidate variety clone F and wild clone H. Three clones showed distinct resistances to CaHV. Moreover, 8772, 8679 and 10,982 differentially expressed unigenes (DEUs) were identified from comparative transcriptomes between diseased individuals and control individuals of clone A+, F and H, respectively. Comprehensive analysis of the shared DEUs in all three clones displayed common defense pathways to the herpesvirus infection, activating IFN system and suppressing complements. KEGG pathway analysis of specifically changed DEUs in respective clones revealed distinct immune responses to the herpesvirus infection. The DEU numbers identified from clone H in KEGG immune-related pathways, such as “chemokine signaling pathway”, “Toll-like receptor signaling pathway” and others, were remarkably much more than those from clone A+ and F. Several IFN-related genes, including Mx1, viperin, PKR and others, showed higher increases in the resistant clone H than that in the others. IFNphi3, IFI44-like and Gig2 displayed the highest expression in clone F and IRF1 uniquely increased in susceptible clone A+. In contrast to strong immune defense in resistant clone H, susceptible clone A+ showed remarkable up-regulation of genes related to apoptosis or death, indicating that clone A+ failed to resist virus offensive and evidently induced apoptosis or death. Conclusions Our study is the first attempt to screen distinct resistances and immune responses of three gynogenetic gibel carp clones to herpesvirus infection by comprehensive transcriptomes. These differential DEUs, immune-related pathways and IFN system genes identified from susceptible and resistant clones will be beneficial to marker-assisted selection (MAS) breeding or molecular module-based resistance breeding in gibel carp.

Bello-Perez M, Falco A, Medina R, Encinar JA, Novoa B, Perez L, Estepa A, Coll J. Structure and functionalities of the human c-reactive protein compared to the zebrafish multigene family of c-reactive-like proteins. DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2017; 69:33-40. [PMID: 27965017 DOI: 10.1016/j.dci.2016.12.001] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/17/2016] [Revised: 12/05/2016] [Accepted: 12/05/2016] [Indexed: 06/06/2023]
Abstract
Because of the recent discovery of multiple c-reactive protein (crp)-like genes in zebrafish (Danio rerio) with predicted heterogeneous phospholipid-binding amino acid sequences and heterogeneous transcript expression levels in viral survivors and adaptive-deficient mutants, zebrafish constitute an attractive new model for exploring the evolution of these protein's functions, including their possible participation in fish trained immunity. Circulating human CRP belongs to the short pentraxin family of oligomeric proteins that are characteristic of early acute-phase innate responses and is widely used as a clinical inflammation marker. In contrast to pentameric human CRP (pCRP), zebrafish CRPs are trimeric (tCRP); however monomeric CRP (mCRP) conformations may also be generated when associated with cellular membranes as occurs in humans. Compared to human CRP, zebrafish CRP-like proteins show homologous amino acid sequence stretches that are consistent with, although not yet demonstrated, cysteine-dependent redox switches, calcium-binding spots, phosphocholine-binding pockets, C1q-binding domains, regions interacting with immunoglobulin Fc receptors (FcR), unique mCRP epitopes, mCRP binding peptides to cholesterol-enriched rafts, protease target sites, and/or binding sites to monocyte, macrophage, neutrophils, platelets and/or endothelial cells. Amino acid variations among the zebrafish CRP-like multiprotein family and derived isoforms in these stretches suggest that functional heterogeneity best fits the wide variety of aquatic pathogens. As occurs in humans, phospholipid-tagged tCRP-like multiproteins might also influence local inflammation and induce innate immune responses; however, in addition, different zebrafish tCRP-like proteins and/or isoforms might fine tune new still unknown functions. The information reviewed here could be of value for future studies not only to comparative but also medical immunologists and/or fisheries sectors. This review also introduces some novel speculations for future studies.

Abstract
Zebrafish (Danio rerio) has become an increasingly important model for in vivo and in vitro studies on host-pathogen interaction, offering scientists with optical accessibility and genetic tractability, and a vertebrate-type immunity that can be separated into innate and adaptive ones. Although it is shown in previous studies that few species of viruses can naturally infect zebrafish, the spring viraemia of carp virus (SVCV), a rhabdovirus that causes contagious acute hemorrhagic viraemia in a variety of cyprinid fishes, can infect zebrafish by both injection and static immersion methods in laboratory conditions. In addition, SVCV can infect zebrafish fibroblast cell line (ZF4 cells), together with the Epithelioma papulosum cyprini (EPC) cell line (EPC cells), a common cell line used widely in fish disease research. The infection and propagation of SVCV in zebrafish and especially in these cell lines can be employed conveniently in laboratory for functional assays of zebrafish genes. The zebrafish, ZF4 and EPC cell, and SVCV can serve as a simple and efficient model system in understanding host-virus interactions. In the present chapter, we provide detailed protocols for the host-virus interaction analysis based on zebrafish embryos, ZF4/EPC cells, and SVCV, including infection methods of zebrafish embryos and cell lines, analyses of immune responses by quantitative PCR (qPCR) and RNA sequencing (RNA-Seq), antiviral assays based on ZF4 and EPC cells, and the analysis of host-virus interaction using luciferase assays. These protocols should provide efficient and typical means to address host-virus interactions in a more general biological sense.

Abstract
The interaction host-intestinal microbiota is essential for the immunological homeostasis of the host. Probiotics, prebiotics and synbiotics are promising tools for the manipulation of the intestinal microbiota towards beneficial effects to the host. The objective of this study was to evaluate the modulation effect on the intestinal microbiota and the transcription of genes involved in the immune response in head kidney of Solea senegalensis after administration of diet supplemented with the prebiotic alginate and the probiotic Shewanella putrefaciens Pdp11 CECT 7627 (SpPdp11). The results showed higher adaptability to dietary changes in the intestinal microbiota of fish fed diet with alginate and SpPdp11 together compared to those fish that received an alginate-supplemented diet. The alginate-supplemented diet produced up-regulation of genes encoding proteins involved in immunological responses, such as complement, lysozyme G and transferrin, and oxidative stress, such as NADPH oxidase and glutation peroxidase. On the other hand, the administration of alginate combined with SpPdp11 resulted in a significant increase of the transcription of genes encoding for glutation peroxidase and HSP70, indicating a potential protective effect of SpPdp11 against oxidative stress. In addition, these effects were maintained after the suspension of the probiotic treatment. The relationship between the modulation of the intestinal microbiota and the expression of genes with protective effect against the oxidative stress was demonstrated by the Principal Components Analysis.

Abstract
There is a constant need to increase the efficiency of vaccines in the aquaculture industry. Although several nano-based vaccine formulations have been reported, to the best of our knowledge so far only one of them have been implemented in the industry. Here we report on chitosan-poly(I:C) nanoparticles (NPs) that could be used as a non-specific adjuvant in antiviral vaccines in aquaculture. We have characterized the physical parameters of the NPs, studied the in vivo and in vitro bio-distribution of fluorescent NPs and verified NP uptake by zebrafish leucocytes. We used the zebrafish model to test the protective efficiency of the recombinant glycoprotein G (rgpG) of VHSV compared to inactivated whole virus (iV) against VHSV using NPs as an adjuvant in both formulations. In parallel we tested free poly(I:C) and rgpG (pICrgpG), and free chitosan and rgpG (CSrgpG) vaccine formulations. While the iV group (with NP adjuvant) provided the highest overall survival, all vaccine formulations with poly(I:C) provided a significant protection against VHSV; possibly through an early induction of an anti-viral state. Our results suggest that chitosan-poly(I:C) NPs are a promising adjuvant candidate for future vaccine formulations.

Abstract
Immersion-vaccines (bacterins) are routinely used for aquacultured rainbow trout to protect against Yersinia ruckeri (Yr). During immersion vaccination, rainbow trout take up and process the antigens, which induce protection. The zebrafish was used as a model organism to study uptake mechanisms and subsequent antigen transport in fish. A genetically modified Yr was developed to constitutively express green fluorescent protein (GFP) and was used for bacterin production. Larval, juvenile and adult transparent zebrafish (tra:nac mutant) received a bath in the bacterin for up to 30 minutes. Samples were taken after 1 min, 15 min, 30 min, 2 h, 12 h and 24 h. At each sampling point fish were used for live imaging of the uptake using a fluorescence stereomicroscope and for immunohistochemistry (IHC). In adult fish, the bacterin could be traced within 30 min in scale pockets, skin, oesophagus, intestine and fins. Within two hours post bath (pb) Yr-antigens were visible in the spleen and at 24 h in liver and kidney. Bacteria were associated with the gills, but uptake at this location was limited. Antigens were rarely detected in the blood and never in the nares. In juvenile fish uptake of the bacterin was seen in the intestine 30 min pb and in the nares 2 hpb but never in scale pockets. Antigens were detected in the spleen 12 hpb. Zebrafish larvae exhibited major Yr uptake only in the mid-intestine enterocytes 24 hpb. The different life stages of zebrafish varied with regard to uptake locations, however the gut was consistently a major uptake site. Zebrafish and rainbow trout tend to have similar uptake mechanisms following immersion or bath vaccination, which points towards zebrafish as a suitable model organism for this aquacultured species.

Abstract
The presence of subclinical infection or clinical disease in laboratory zebrafish may have a significant impact on research results, animal health and welfare, and transfer of animals between institutions. As use of zebrafish as a model of disease increases, a harmonized method for monitoring and reporting the health status of animals will facilitate the transfer of animals, allow institutions to exclude diseases that may negatively impact their research programs, and improve animal health and welfare. All zebrafish facilities should implement a health monitoring program. In this study, we review important aspects of a health monitoring program, including choice of agents, samples for testing, available testing methodologies, housing and husbandry, cost, test subjects, and a harmonized method for reporting results. Facilities may use these recommendations to implement their own health monitoring program.

Abstract
CD36 is a transmembrane glycoprotein belonging to the scavenger receptor class B family which plays crucial roles in innate immunity. Although CD36 is widely documented in mammals, the study of its functions in fish is still limited. Here we report the identification of a zebrafish cd36 homologue. Zebrafish cd36 has a higher gene expression in the tissues of intestine and liver but very low in kidney and swim bladder. We find cd36 mRNA is maternally expressed and is mainly restricted to the intestine, branchial arches and regions around the lips after the segmentation stage during embryogenesis. Functionally, the recombinant Cd36 corresponding to the large extracellular loop is capable of binding both the Gram-negative and Gram-positive bacteria. These results indicate that zebrafish Cd36 is a microbial-binding molecule. The study expands our knowledge of the function of scavenger receptor molecules in fish innate immune process.

Abstract
The complement components C8α, C8β and C9 have important roles in the innate immune system against invading microorganisms. Partial cDNA sequences of the Pf_C8α, Pf_C8β and Pf_C9 genes (Pf: abbreviation of Pelteobagrusfulvidraco) were cloned from yellow catfish. The Pf_C8α, Pf_C8β and Pf_C9 genes showed the greatest amino acid similarity to C8α (54%) and C8β (62%) of zebrafish and to C9 (52%) of grass carp, respectively. Ontogenetic expression analyses using real-time quantitative PCR suggested that the three genes may play crucial roles during embryonic and early larval development. The mRNA expressions of the three genes were all at the highest levels in liver tissue, and at lower or much lower levels in 16 other tissues, demonstrating that the liver is the primary site for the protein synthesis of Pf_C8α, Pf_C8β and Pf_C9. Injection of Aeromonashydrophila led to up-regulation of the three genes in the spleen, head kidney, kidney, liver and blood tissues, indicating that the three genes may contribute to the host’s defense against invading pathogenic microbes. An increased understanding of the functions of the Pf_C8α, Pf_C8β and Pf_C9 genes in the innate immunity of yellow catfish will help enhance production of this valuable freshwater species.

Abstract
While exploring the molecular mechanisms behind the fin hemorrhages that follow zebrafish (Danio rerio) early infection with viral haemorrhagic septicemia virus (VHSV), we discovered that most serpin (serine protease inhibitor) gene transcripts were upregulated, except those of serpine1. Surprisingly, only SERPINe1-derived 14-mer peptide and low molecular weight drugs targeting SERPINe1 (i.e. tannic acid, EGCG, tiplaxtinin) inhibited in vitro infections not only of VHSV, but also of other fish rhabdoviruses such as infectious hematopoietic necrosis virus (IHNV) and spring viremia carp virus (SVCV). While the mechanisms that inhibited rhabdoviral infections remain speculative, these and other results suggested that SERPINEe1-derived peptide specifically targeted viral infectivity rather than virions. Practical applications might be developed from these studies since preliminary evidences showed that tannic acid could be used to reduce VHSV-caused mortalities. These studies are an example of how the identification of host genes targeted by viral infections using microarrays might facilitate the identification of novel prevention drugs in aquaculture and illuminate viral infection mechanisms.

Abstract
There is an urgent need for more efficient viral vaccines in finfish aquaculture worldwide. Here, we report the use of poly(I:C) stabilized with chitosan as an adjuvant for development of better finfish vaccines. The adjuvant was co-injected with inactivated viral hemorrhagic septicemia virus (VHSV) (CSpIC+iV vaccine) in adult zebrafish and its efficiency in protection against VHSV infection was compared to a live, attenuated VHS virus vaccine (aV). Both free and stabilized poly(I:C) were strong inducers of an antiviral state, measured by transcriptional activation of the genes of viral sensors: toll-like receptors, interferons, and interferon-stimulated genes, such as MXa within 48 h after injection. Both the CSpIC+iV and the aV formulations provided a significant protection against VHSV-induced mortality. However, when plasma from survivors was tested for neutralizing antibodies in an in vitro protection assay, we could not demonstrate any protective effect. On the contrary, plasma from aV vaccinated fish enhanced cytopathic effects, indicating that antibody-dependent entry may play a role in this system. Our results show that poly(I:C) is a promising candidate as an adjuvant for fish vaccination against viral pathogens, and that the zebrafish is a promising model for aquaculture-relevant vaccination studies.

Abstract
Since adaptive features such as memory were discovered in mammalian innate immunity, interest in the immunological status of primitive vertebrates after infections has grown. In this context, we used zebrafish (Danio rerio), a primitive vertebrate species suited to molecular and genetic studies to explore transcriptional memories of the immune system in long-term survivors of viral haemorrhagic septicemia virus infections. Immune-gene targeted microarrays designed in-house, multipath genes, gene set enrichment, and leading-edge analysis, reveal unexpected consistent correlations between the viral-survivor phenotype and several innate multigene families. Thus, here we describe in survivors of infections the upregulation of the multigene family of proteasome subunit macropains, zebrafish-specific novel gene sets, mitogen activated protein kinases, and epidermal growth factor. We also describe the downregulation of the multigene families of c-reactive proteins, myxovirus-induced proteins and novel immunoglobulin-type receptors. The strength of those immunological memories was reflected by the exceptional similarity of the transcriptional profiles of survivors before and after re-infection compared with primary infected fish. On the other hand, the high levels of neutralizing antibodies in the blood plasma of survivors contrasted with the depletion of transcripts specific for most cell types present in lymphoid organs. Therefore, long-term survivors maintained unexpected molecular/cellular memories of previous viral encounters by modulating the expression levels of innate multigene families as well as having specific adaptive antibodies. The implications of the so-called "trained immunity" for future research in this field are also discussed.

Overlapping and unique signatures in the proteomic and transcriptomic responses of the nematode Caenorhabditis elegans toward pathogenic Bacillus thuringiensis. DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2015; 51:1-9.

Abstract
Pathogen infection can activate multiple signaling cascades that ultimately alter the abundance of molecules in cells. This change can be measured both at the transcript and protein level. Studies analyzing the immune response at both levels are, however, rare. Here, we compare transcriptome and proteome data generated after infection of the nematode and model organism Caenorhabditis elegans with the Gram-positive pathogen Bacillus thuringiensis. Our analysis revealed a high overlap between abundance changes of corresponding transcripts and gene products, especially for genes encoding C-type lectin domain-containing proteins, indicating their particular role in worm immunity. We additionally identified a unique signature at the proteome level, suggesting that the C. elegans response to infection is shaped by changes beyond transcription. Such effects appear to be influenced by AMP-activated protein kinases (AMPKs), which may thus represent previously unknown regulators of C. elegans immune defense.

Abstract
Inshore winter flounder (Pseudoplueronectes americanus) populations in NY, USA have reached record low numbers in recent years, and recruitment into the fishery appears to be limited by survival of post-settlement juvenile fish. In order to identify cellular pathways associated with site-specific variation in condition and mortality, we examined differential mRNA expression in juvenile winter flounder collected from six different bays across a gradient in human population density and sewage inputs. Illumina sequencing of pooled samples of flounder from contrasting degraded sites and less impacted sites was used to guide our choice of targets for qPCR analysis. 253 transcripts of >100bp were differentially expressed, with 60% showing strong homology to mostly teleost sequences within the NCBI database. Based on these data, transcripts representing nine genes of interest associated with contaminant exposure, immune response and glucose and glycogen metabolism were examined by qPCR in individual flounder from each site. Statistically significant site-specific differences were observed in expression of all but one gene, although patterns in expression were complex with only one (vitellogenin), demonstrating a west to east gradient consistent with known loadings of municipal sewage effluent. Principal components analysis (PCA) identified relationships among the genes evaluated. Our data indicate that juvenile winter flounder are responding to estrogenic chemicals in more urbanized coastal bays, and suggests potential mechanistic links between immune response, contaminant exposure and energy metabolism.

Groh KJ, Suter MJF. Stressor-induced proteome alterations in zebrafish: a meta-analysis of response patterns. AQUATIC TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2015; 159:1-12.

Abstract
Proteomics approaches are being increasingly applied in ecotoxicology on the premise that the identification of specific protein expression changes in response to a particular chemical would allow elucidation of the underlying molecular pathways leading to an adverse effect. This in turn is expected to promote the development of focused testing strategies for specific groups of toxicants. Although both gel-based and gel-free global characterization techniques provide limited proteome coverage, the conclusions regarding the cellular processes affected are still being drawn based on the few changes detected. To investigate how specific the detected responses are, we analyzed a set of studies that characterized proteome alterations induced by various physiological, chemical and biological stressors in zebrafish, a popular model organism. Our analysis highlights several proteins and protein groups, including heat shock and oxidative stress defense proteins, energy metabolism enzymes and cytoskeletal proteins, to be most frequently identified as responding to diverse stressors. In contrast, other potentially more specifically responding protein groups are detected much less frequently. Thus, zebrafish proteome responses to stress reported by different studies appear to depend mostly on the level of stress rather than on the specific stressor itself. This suggests that the most broadly used current proteomics technologies do not provide sufficient proteome coverage to allow in-depth investigation of specific mechanisms of toxicant action. We suggest that the results of any differential proteomics experiment performed with zebrafish should be interpreted keeping in mind the list of the most frequent responders that we have identified. Similar reservations should apply to any other species where proteome responses are analyzed by global proteomics methods. Careful consideration of the reliability and significance of observed changes is necessary in order not to over-interpret the experimental results and to prevent the proliferation of false positive linkages between the chemical and the cellular functions it perturbs. We further discuss the implications of the identified "top lists" of frequently responding proteins and protein families, and suggest further directions for proteomics research in ecotoxicology. Apart from improving the proteome coverage, further research should focus on defining the significance of the observed stress response patterns for organism phenotypes and on searching for common upstream regulators that can be targeted by specific assays.

Abstract
Skin plays an important role in innate immune responses to bacterial infection, but its molecular mechanism remains unclear in fish. The transcriptional profiling of the skin immune response to Aeromonas hydrophila infection of the zebrafish, Danio rerio (Hamilton), was performed by Affymetrix microarray analysis. The results showed that 538 genes were differentially expressed, of which 388 genes were up-regulated and 150 genes were down-regulated. The expression patterns for 106 representative genes were observed to be up-regulated in zebrafish skin at 24 and 36 h post-infection, and gene expression changes were clearly greater at 36 h. Gene Ontology classification indicated that 222 genes were significantly associated with the skin immunity, including complement activation, acute-phase response, stress response, chemotaxis and apoptosis. Further Kyoto Encyclopedia of Genes and Genomes analysis showed that the significant pathways included MAPK, p53, Wnt, TGF-β, Notch, ErbB, JAK-STAT, VEGF, mTOR and Calcium signalling in skin immune responses, and several genes (e.g. akt2l, frap1, nras, rac1, xiap) were found to be involved in signalling networks. Moreover, expression changes in nine selected genes were verified by real-time qPCR analysis. This is the first known report on transcriptome analysis in the skin of zebrafish against the pathogen A. hydrophila.

Specific nucleotides at the 3'-terminal promoter of viral hemorrhagic septicemia virus are important for virulence in vitro and in vivo. Virology 2014; 476:226-232.

Abstract
Viral hemorrhagic septicemia virus (VHSV), a member of the Novirhabdovirus genus, contains an 11-nucleotide conserved sequence at the terminal 3'- and 5'-untranslated regions (UTRs) that are complementary. To study the importance of nucleotides in the 3'-UTR of VHSV for replication of novirhabdoviruses, we performed site-directed mutagenesis of selected residues at the 3'-terminus and generated mutant viruses using a reverse genetics approach. Assessment of growth kinetics and in vitro real-time cytopathogenicity studies showed that the order of two nucleotides (A4G5) of the 3'-terminus of VHSV directly affects growth kinetics in vitro. The mutant A4G-G5A virus has reduced total positive-strand RNA synthesis efficiency (51% of wild-type) at 48h post-transfection and 70h delay in causing complete cytopathic effect in susceptible fish cells, as compared to the WT-VHSV. Furthermore, when the A4G-G5A virus was used to challenge zebrafish, it exhibited reduced pathogenicity (54% lower end-point mortality) compared to the WT-VHSV. From these studies, we infer that specific residues in the 3'-UTR of VHSV have a promoter function and are essential to modulate the virulence in cells and pathogenicity in fish.

Abstract
We have recently identified the two major determinants of the glycoprotein G of the viral hemorrhagic septicaemia rhabdovirus (gpGVHSV), peptides p31 and p33 implicated in triggering the host type I IFN antiviral response associated to these rhabdoviral antigens. With the aim to investigate the properties of these viral glycoprotein regions as DNA molecular adjuvants, their corresponding cDNA sequences were cloned into a plasmid (pMCV1.4) flanked by the signal peptide and transmembrane sequences of gpGVHSV. In addition, a plasmid construct encoding both sequences p31 and p33 (pMCV1.4-p31+p33) was also designed. In vitro transitory cell transfection assays showed that these VHSV gpG regions were able to induce the expression of type I IFN stimulated genes as well as to confer resistance to the infection with a different fish rhabdovirus, the spring viremia of carp virus (SVCV). In vivo, zebrafish intramuscular injection of only 1μg of the construct pMCV1.4-p31+p33 conferred fish protection against SVCV lethal challenge up to 45 days post-immunization. Moreover, pMCV1.4-p31+p33 construct was assayed for molecular adjuvantcity's for a DNA vaccine against SVCV based in the surface antigen of this virus (pAE6-GSVCV). The results showed that the co-injection of the SVCV DNA vaccine and the molecular adjuvant allowed (i) a ten-fold reduction in the dose of pAE6-Gsvcv without compromising its efficacy (ii) an increase in the duration of protection, and (iii) an increase in the survival rate. To our knowledge, this is the first report in which specific IFN-inducing regions from a viral gpG are used to design more-efficient and cost-effective viral vaccines, as well as to improve our knowledge on how to stimulate the innate immune system.

Abstract
Seasonal influenza virus infections cause annual epidemics and sporadic pandemics. These present a global health concern, resulting in substantial morbidity, mortality and economic burdens. Prevention and treatment of influenza illness is difficult due to the high mutation rate of the virus, the emergence of new virus strains and increasing antiviral resistance. Animal models of influenza infection are crucial to our gaining a better understanding of the pathogenesis of and host response to influenza infection, and for screening antiviral compounds. However, the current animal models used for influenza research are not amenable to visualization of host-pathogen interactions or high-throughput drug screening. The zebrafish is widely recognized as a valuable model system for infectious disease research and therapeutic drug testing. Here, we describe a zebrafish model for human influenza A virus (IAV) infection and show that zebrafish embryos are susceptible to challenge with both influenza A strains APR8 and X-31 (Aichi). Influenza-infected zebrafish show an increase in viral burden and mortality over time. The expression of innate antiviral genes, the gross pathology and the histopathology in infected zebrafish recapitulate clinical symptoms of influenza infections in humans. This is the first time that zebrafish embryos have been infected with a fluorescent IAV in order to visualize infection in a live vertebrate host, revealing a pattern of vascular endothelial infection. Treatment of infected zebrafish with a known anti-influenza compound, Zanamivir, reduced mortality and the expression of a fluorescent viral gene product, demonstrating the validity of this model to screen for potential antiviral drugs. The zebrafish model system has provided invaluable insights into host-pathogen interactions for a range of infectious diseases. Here, we demonstrate a novel use of this species for IAV research. This model has great potential to advance our understanding of influenza infection and the associated host innate immune response.

Abstract
Neutrophils are the most abundant polymorphonuclear leukocytes, presenting the first line of defence against infection or tissue damage. To characterize the molecular changes on the protein level in neutrophils during sterile inflammation we established the chemically-induced inflammation (ChIn) assay in adult zebrafish and investigated the proteome dynamics within neutrophils of adult zebrafish upon inflammation. Through label-free proteomics we identified 48 proteins that were differentially regulated during inflammation. Gene ontology analysis revealed that these proteins were associated with cell cycle, nitric oxide signalling, regulation of cytoskeleton rearrangement and intermediate filaments as well as immune-related processes such as antigen presentation, leucocyte chemotaxis and IL-6 signalling. Comparison of protein expression dynamics with transcript expression dynamics suggests the existence of regulatory mechanisms confined to the protein level for some genes. This is the first proteome analysis of adult zebrafish neutrophils upon chemically-induced inflammation providing a valuable reference for future studies using zebrafish inflammation models.
