Abstract
IMPORTANCE The expression of circVPS13D was upregulated with SCRV invasion, which proved that circVPS13D was involved in the regulation of the antiviral immune response. Our study revealed that the existence of circVPS13D promoted the replication of SCRV. Functionally, circVPS13D negatively regulates the antiviral responses of fish. Mechanistically, we confirmed that circVPS13D inhibited RLRs antiviral signaling pathway via the encoded protein VPS13D-170aa by targeting MAVS. Our study provided novel insights into the roles of protein-coding circRNAs and supported VPS13D-170aa as a negative regulator in the antiviral immune responses of teleost fish.

Abstract
Polymeric (p) immunoglobulins (Igs) serve broad functions during vertebrate immune responses. Typically, pIgs contain between two and six Ig monomers, each with two antigen binding fragments and one fragment crystallization (Fc). In addition, many pIgs assemble with a joining-chain (JC); however, the number of monomers and potential to include JC vary with species and heavy chain class. Here, we report the cryo-electron microscopy structure of IgM from a teleost (t) species, which does not encode JC. The structure reveals four tIgM Fcs linked through eight C-terminal tailpieces (Tps), which adopt a single β-sandwich-like domain (Tp assembly) located between two Fcs. Specifically, two of eight heavy chains fold uniquely, resulting in a structure distinct from mammalian IgM, which typically contains five IgM monomers, one JC and a centrally-located Tp assembly. Together with mutational analysis, structural data indicate that pIgs have evolved a range of assembly mechanisms and structures, each likely to support unique antibody effector functions.

Abstract
IMPORTANCE Increasing evidence indicates that circular RNAs exert crucial functions in regulating gene expression in mammals. However, the function of circRNAs in lower vertebrates still needs further exploration. Our research results demonstrated that circRNA, namely circCBL, is involved in modulating antiviral and antibacterial immune responses in lower vertebrates. In addition, our study also found that circCBL can serve as a competing endogenous RNA to facilitate MITA expression, thereby modulating MITA-mediated innate immunity. Further research has proved that the host gene CBL also promotes the expression of MITA, enhancing antiviral and antibacterial immune responses. Our study not only elucidated the underlying biological mechanism of the circRNA-miRNA-mRNA axis in the innate immune response of lower vertebrates but also unveiled the synergistic antibacterial and antiviral mechanisms between circRNA and its host gene in lower vertebrates.

Abstract
Sturgeons are chondrostean fish critically endangered due to anthropogenic loss and degradation of natural habitat and overfishing for meat and caviar production. Consequently, sturgeon aquaculture has extensively developed lately, being Russian sturgeon (Acipenser gueldenstaedtii) the second most important species reared for caviar production. However, Russian sturgeon aquaculture in subtropical countries, such as Uruguay, confronts difficulties because fish have to endure excessive summertime warm temperatures, which weaken their innate defences facilitating opportunistic infections. To address this problem, we look for identifying putative acute phase proteins (APPs), which might be robust serum biomarkers of both infection and chronic thermal stress, applied to monitoring Russian sturgeon health status in farms. We focused on the C-Reactive Protein/Serum Amyloid P (CRP/SAP) pentraxin since the pentraxin family includes well-known APPs, better characterised in mammals than fish. We identified A.gueldenstaedtii CRP/SAP (AgCRP/SAP), as a member of the universal CRP/SAP pentraxin sub-family, and studied AgCRP/SAP involvement in sturgeon response to bacterial challenge and chronic thermal stress, in comparison with A. gueldenstaedtii Serum Amyloid A (AgSAA), a previously described positive APP. Results showed that AgCRP/SAP is a constitutive serum component that remained constant upon Aeromonas hydrophila challenge and chronic thermal stress. Contrastingly, serum AgSAA was subjected to regulation by bacterial and thermal stress challenges, showing a 50-fold increase and 3-fold decline in serum levels, respectively. Overall, results highlight the potential value of AgSAA, but not of AgCRP/SAP, as a biomarker of bacterial infection and the need to continue searching for robust chronic thermal stress biomarkers in sturgeons.

Abstract
Rodlet cells (RCs) are the enigmatic and distinctive pear-shaped cells had found in many tissues of marine and freshwater teleosts. They have a distinctive fibrous capsule or the cell cortex that envelopes conspicuous inclusions called rodlets, basally situated nucleus, and poorly developed mitochondria. The contraction of the cell cortex results in the expulsion of the cell contents through an apical opening. One hundred and thirty years since rodlet cells were first reported, many questions remain about their origin and a function. This review will present new evidence regarding the relationship between RCs and metazoan parasites, and a protozoan infecting organs of different fish species, and update the state of knowledge about the origin, structure and the function of these intriguing fish cells.

Abstract
The immune system is a complex and sophisticated biological system, spanning multiple levels of complexity, from the molecular level to that of tissue. Our current understanding of its function and complexity, of the heterogeneity of leukocytes, is a result of decades of concentrated efforts to delineate cellular markers using conventional methods of antibody screening and antigen identification. In mammalian models, this led to in-depth understanding of individual leukocyte subsets, their phenotypes, and their roles in health and disease. The field was further propelled forward by the development of single-cell (sc) RNA-seq technologies, offering an even broader and more integrated view of how cells work together to generate a particular response. Consequently, the adoption of scRNA-seq revealed the unexpected plasticity and heterogeneity of leukocyte populations and shifted several long-standing paradigms of immunology. This review article highlights the unprecedented opportunities offered by scRNA-seq technology to unveil the individual contributions of leukocyte subsets and their crosstalk in generating the overall immune responses in bony fishes. Single-cell transcriptomics allow identifying unseen relationships, and formulating novel hypotheses tailored for teleost species, without the need to rely on the limited number of fish-specific antibodies and pre-selected markers. Several recent studies on single-cell transcriptomes of fish have already identified previously unnoticed expression signatures and provided astonishing insights into the diversity of teleost leukocytes and the evolution of vertebrate immunity. Without a doubt, scRNA-seq in tandem with bioinformatics tools and state-of-the-art methods, will facilitate studying the teleost immune system by not only defining key markers, but also teaching us about lymphoid tissue organization, development/differentiation, cell-cell interactions, antigen receptor repertoires, states of health and disease, all across time and space in fishes. These advances will invite more researchers to develop the tools necessary to explore the immunology of fishes, which remain non-conventional animal models from which we have much to learn.

Abstract
The PI3K/AKT/p53 signaling pathway is activated by various types of cellular stimuli or pathogenic infection, and then regulates fundamental cellular functions to combat these stimulations. Here, we studied the meaningful roles of PI3K/AKT/p53 in regulating cellular machine such as autophagy, immune responses, as well as antiviral activity in Chinese perch brain (CPB) cells infected by infectious spleen and kidney necrosis virus (ISKNV), which is an agent caused devastating losses in mandarin fish (Siniperca chuatsi) industry. We found that ISKNV infection induced up-regulation of host PI3K/AKT/p53 axis, but inhibited autophagy in CPB cells. Interestingly, activation of PI3K/AKT/p53 axis factors trough agonists or overexpression dramatically decreased host autophagy level, inhibited ISKNV replication, and elevated the expression of immune-related genes in CPB cells. In contrast, suppression of PI3K/AKT/p53 pathway by inhibitors or small interfering RNA (siRNA)-mediated gene silence increased the autophagy and ISKNV replication, but down-regulated immune responses in CPB cells. All these results indicate that PI3K/AKT/p53 pathway plays an important role in anti-ISKNV infection and can be used as a new target for controlling ISKNV disease.

Abstract
Aquaculture plays an increasingly significant role in improving the sustainability of global fish production. This sector has been intensified with the advent of new husbandry practices and the development of new technology. However, the increasing intensification and indiscriminate commercialized farming has enhanced the vulnerability of cultivated aquatic species to damage from pathogens. In efforts to confront these various diseases, frequent use of drugs, antibiotics, chemotherapeutics, and agents for sterilization have unintentionally added to the risk of transmission of pathogens and harmful chemical compounds to consumers. Some natural dietary supplements are believed to have the potential to offset this setback in aquaculture. Application of bio-friendly feed additives such as probiotics, prebiotics and synbiotics are becoming popular dietary supplements with the potential to not only improve growth performance, but in some cases can also enhance immune competence and the overall well-being of fish and crustaceans. The present review discusses and summarizes the effects of probiotics, prebiotics and synbiotics application on growth, stress mitigation, microbial composition of intestine, immune system and health condition of aquatic animals in association with existing constraints and future perspectives in aquaculture.

Abstract
Numerous studies have demonstrated that Cryptocaryon irritans can efficiently propagate in golden pompano (Trachinotus blochii), especially under intensive high-density culture, which can lead to large-scale infection, bacterial invasion, and major economic losses. By contrast, Siganus oramin is less susceptible to C. irritans infection. Here, we artificially infected S. oramin and T. blochii with C. irritans. We then used RNA-seq to characterize the expression of genes in the gills of S. oramin and T. blochii at different times after infection, conducted bioinformatics analysis of relevant pathways, and compared the differentially expressed genes in the two species. The aim of this study was to enhance our understanding of host-parasite interactions to aid the development of effective prevention and treatment strategies for C. irritans. Infection with C. irritans induced the differential expression of a large number of genes in the gills of S. oramin, indicating that S. oramin may respond to C. irritans infection by modifying the expression of genes at the transcriptional level. Our research showed that the Toll-like receptor signaling pathway, Antigen processing and presentation, Complement and coagulation cascades, and Cytosolic DNA-sensing pathway are involved in the immune response of S. oramin and T. blochii to C. irritans infection. However, T. blochii has a weak ability to mobilize neutrophils to participate in defense against C. irritans infection and differs from S. oramin in its ability to induce specific immune responses. Because of gill tissue damage during infection, dissolved oxygen intake is reduced, which increases physiological and metabolic stress. The metabolic pathways of S. oramin and T. blochii significantly differed; specifically, the main pathways in S. oramin were related to glucose and lipid metabolism, and the main pathways in T. blochii were related to amino acid metabolism. This may reduce the efficiency of ATP biosynthesis in T. blochii and result in dysfunctional energy metabolism. Therefore, differential immune and metabolic responses underlie differences in the resistance of S. oramin and T. blochii to C. irritans.

Abstract
The current study addressed to investigate the effect of lycopene (LYC) on blood physiology, digestive-antioxidant enzyme activity, specific-nonspecific immune response, and inflammatory gene transcriptional regulation (cytokines, heat shock proteins, vitellogenins) in spotted snakehead (Channa punctata) against Pseudomonas aeruginosa. In unchallenged and challenged fish treated with 200 mg LYC enriched diet the growth performance and digestive-antioxidant enzymes increased after 30 days, whereas with inclusion of 100 or 400 mg LYC in the diets, the increase manifested on or after 45 days. No mortality in fish treated with any LYC diet against P. aeruginosa was revealed. In the unchallenged and challenged fish the phagocytic (PC) activity in head kidney (HK) and spleen were significantly enhanced when fed the control diet or other LYC diets, whereas the respiratory burst (RB) activity and nitric oxide (NO) production significantly increased when fed the 200 mg diet for 45 and 60 days. Similarly, the lysozyme (Lyz) activity in the HK and spleen, and total Ig content in serum were significantly higher in both groups fed the 200 mg LYC diet for 15, 45, and 60 days. Heat shock protein (Hsp 70) was significantly improved in the uninfected group fed the 200 mg LYC diet for 45 and 60 days, but Hsp27 did not significantly change among the experimental groups at any time points. TNF-α and IL-6 mRNA pro-inflammatory cytokine expression significantly increased in both groups fed the 200 mg LYC diet after 45 and 60 days, while the IL-12 mRNA expression was moderate in both groups fed the same diet for 60 days. The IL-10 did not significant mRNA expression between groups at any sampling. The iNOS and NF-κB mRNA expression was pointedly high in both groups fed the 200 mg LYC diet on day 45 and 60. Vitellogenin A (VgA) mRNA was significantly higher in the uninfected fish fed the 100 and 200 mg LYC diets for 45 and 60 days, but VgB did not reveal significant difference between the treatment groups at any time points. The present results suggest that supplementation of LYC at 200 mg significantly modulate the blood physiology, digestive-antioxidant enzymes, specific-nonspecific immune parameters, and cytokines, Hsp, and vitellogenins in spotted snakehead against P. aeruginosa.

Abstract
In this study, a c-type lysozyme gene (BsLyzC) was identified and characterized from a marine fish, Bostrychus sinensis. The BsLyzC encodes 154 amino acids and contains a signal peptide of 17 amino acids, two catalytic residues and eight cysteine residues. The genomic DNA of BsLyzC consists of four exons and three introns. The BsLyzC shares high sequence similarity with c-type lysozyme from other fish species. The qPCR assays indicated that the BsLyzC exhibited a constitutive expression pattern in eleven examined tissues of healthy B. sinensis individuals. The transcripts of BsLyzC could be significantly induced after infection of Vibrio parahemolyticus in blood, spleen and head kidney. The optimal temperature and pH for recombinant BsLyzC (rBsLyzC) were found to be 50 °C and 6.0, respectively. The rBsLyzC exhibited antibacterial activities against two Gram-positive bacteria and two Gram-negative bacteria. These results indicate that the BsLyzC is involved in the antibacterial immunity of B. sinensis.

Abstract
Interleukin-1β is a key pro-inflammatory cytokine functioning in initiation of inflammatory responses against bacterial- and viral-infections. In the present study, a putative IL-1β counterpart was identified from Siberian sturgeon (Acipenser baeri) and designated as AbIL-1β. The Abil-1β cDNA sequence consists of 1130 bp with an open reading frame (ORF) of 585 bp, which encodes a 194 amino acid (aa) protein. Multiple amino acid sequence alignment revealed that a possible mature peptide could start at Leu18, although no cut site for ICE (IL-1β converting enzyme) enzyme was present in Siberian sturgeon IL-1β. Even if AbIL-1β shares a relative low identity (33.6%) with another sturgeon type II IL-1β gene from Acipenser dabryanus, they still clustered together in phylogenetic tree. Endogenous Abil-1β was highly expressed in brain, blood, head kidney and spleen of healthy Siberian sturgeon, and remarkably up regulated in head kidney, spleen, and liver upon Aeromonas hydrophila (A.h) challenge. Consistently, in vitro stimulation test using heat-killed A.h and LPS significantly increased Abil-1β transcripts of primary spleen cells. To investigate the bactericidal capability of AbIL-1β, recombinant AbIL-1β (rAbIL-1β) was generated by prokaryotes. Pre-injection of rAbIL-1β reduced the bacterial load in sturgeon spleen after A.h infection. Further, rAbIL-1β was served as feed additive and demonstrated to enhance hybrid sturgeon's defense against A.h infection by increased expressional levels of immune-related genes (IL-1β, IL-6, IL-8, IgM and MHCIIβ), elevated activities of serum lysosome, ACH50, and MPO, as well as higher percent survival. In summary, the current results suggested that AbIL-1β functions in immune regulation and could improve sturgeon's resistance to bacterial infection.

Abstract
Cyanobacteria (blue-green algae) have been present on Earth for over 2 billion years, and can produce a variety of bioactive molecules, such as cyanotoxins. Microcystins (MCs), the most frequently detected cyanotoxins, pose a threat to the aquatic environment and to human health. The classic toxic mechanism of MCs is the inhibition of the protein phosphatases 1 and 2A (PP1 and PP2A). Immunity is known as one of the most important physiological functions in the neuroendocrine-immune network to prevent infections and maintain internal homoeostasis in fish. The present review aimed to summarize existing papers, elaborate on the MC-induced immunotoxicity in fish, and put forward some suggestions for future research. The immunomodulatory effects of MCs in fish depend on the exposure concentrations, doses, time, and routes of exposure. Previous field and laboratory studies provided strong evidence of the associations between MC-induced immunotoxicity and fish death. In our review, we summarized that the immunotoxicity of MCs is primarily characterized by the inhibition of PP1 and PP2A, oxidative stress, immune cell damage, and inflammation, as well as apoptosis. The advances in fish immunoreaction upon encountering MCs will benefit the monitoring and prediction of fish health, helping to achieve an ecotoxicological goal and to ensure the sustainability of species. Future studies concerning MC-induced immunotoxicity should focus on adaptive immunity, the hormesis phenomenon and the synergistic effects of aquatic microbial pathogens.

Abstract
Interferon-induced protein 35 kDa (IFP35) has been demonstrated to play important roles in antiviral defense, inflammatory response and cancer progression. However, its precise function in teleost fish remains to be elucidated. Herein, we functionally characterized the rock bream (Oplegnathus fasciatus) IFP35 (OfIFP35) to understand its expression pattern, subcellular localization, antiviral activity, and regulation of downstream genes. OfIFP35 consists of an 1107 bp open reading frame encoding 368 amino acids, including two N-myc-interactor (Nmi)/IFP35 domains (NIDs). The predicted molecular weight of OfIFP35 was 42 kDa, with a theoretical isoelectric point (pI) of 5.10. Evolutionary conservation of IFP35 was analyzed using multiple, pairwise alignments and phylogenetic tree analysis. OfIFP35 in rock bream was found to be highest expressed in the gills. Immune challenges with iridovirus, polyinosinic:polycytidylic acid, lipopolysaccharide, and live bacteria (Streptococcus iniae and Edwardsiella tarda) significantly upregulated its mRNA expression in gill and liver tissues of the rock bream. GFP-tagged OfIFP35 was localized in the cytoplasm of FHM cells, and its overexpression significantly suppressed VHSV transcription in vitro. Moreover, the analysis of downstream gene expression revealed that OfIFP35 could activate the type I interferon pathway. Collectively, these findings indicate that OfIFP35 is important for the immune system of rock bream as it promotes defense responses during viral infections.

Abstract
Cathepsin B (CTSB) is one of the typical representatives of cysteine protease family. It has the activity of both exopeptidase and endopeptidase. It plays an important role in antigen presentation, degradation, apoptosis, inflammatory response and physiological process of many diseases. In this study, CTSB of Trachinotus ovatus (TroCTSB) was cloned, and its structure and function were analyzed. The results showed that the coding region of TroCTSB was 993 bp, encoding 330 amino acid residues. The homology analysis showed that the amino acid sequence of TroCTSB was similar to that in other teleosts and mammals (68.69%-88.48%). Under normal physiological conditions, TroCTSB was widely distributed in various tissues with the highest expression level in stomach, followed by liver, and the lowest expression level in blood. The optimal pH and temperature of purified recombinant protein rTroCTSB were 5.5 and 40 °C, respectively. The toxicity test of metal ions showed that Fe2+, Cu2+, Ca2+ and Zn2+ could all inhibit the activity of TroCTSB, with Zn2+ ranking the first. In addition, after Edwardsiella tarda infection, the expression of TroCTSB was significantly up-regulated in liver, spleen and head kidney. The overexpression of TroCTSB significantly inhibited the infection of E. tarda in golden pompano tissues, and the knockdown of TroCTSB remarkably promoted the reproduction of E. tarda in golden pompano tissues in vivo. This study suggests that TroCTSB was involved in the antibacterial immune response of T. ovatus, and provided a reference for further research in elucidating the resistance mechanism of TroCTSB.

Abstract
In fish, type I IFNs are classified into three groups, i.e. Group I, Group II and Group III, which are further divided into seven subgroups according to the number of conservative cysteines, phylogenetic relationship, and probably their receptor complexes. In the present study, four type I IFNs and four cytokine receptor family B members (CRFBs) were identified in the Asian arowana, Scleropages formosus, an ancient species in the Osteoglossomorpha with commercial and conservation values. According to multiple sequence alignment and phylogenetic relationship, the four type I IFNs are named as IFNa1, IFNa2, IFNb and IFNc, with the former two belonging to Group I, and the latter two to Group II. The four receptors are named as CRFB1, CRFB2, CRFB5a and CRFB5b. The IFNs and their possible receptor genes are widely expressed in examined organs/tissues, and are induced following the stimulation of polyinosinic polycytidylic acid (polyI:C) in vivo. It was found that IFNa1, IFNa2, IFNb and IFNc use preferentially the receptor complexes, CRFB1 and CRFB5b, CRFB1 and CRFB5b, CRFB2 and CRFB5a, and CRFB2 and CRFB5b, respectively, indicating the evolutionary diversification in the interaction of type I IFNs and their receptors in this ancient fish species, S. formosus.

Abstract
The objective of this study was to evaluate the toxic effects of Cr6+ on bioaccumulation, digestion, immunity, oxidative stress, apoptosis and inflammation-related genes in Channa asiatica. The fish was exposed to waterborne Cr6+ concentrations (0, 0.5, 1.0 and 2.0 mg/L) for 28 and 56 days. Our results demonstrated that the accumulation of Cr6+ in tissues increased in a concentration-dependent manner, and the content in tissue was liver > gill > gut > muscle. Meanwhile, Cr6+ exposure led to a remarkable suppression of digestion, immunity and antioxidant capacity in C. asiatica. Inversely, MDA and PC content were positively correlated with Cr6+ exposure concentration. Furthermore, the expression of genes went up with the increase of waterborne Cr6+ concentration. Among them, HSP90, NF-κB and TNF-α have a sharp increase. These results elucidate that waterborne Cr6+ exposure may induce bioaccumulation, inhibit digestion and immunity, promote oxidative stress and up-regulate the expression of apoptosis and inflammation-related genes in C. asiatica.

Abstract
Copper-zinc superoxide dismutase (CuZnSOD) is a nuclear-encoded metalloenzyme responsible for scavenging harmful reactive oxygen species (ROS). In this study, the CuZnSOD homolog from redlip mullet (Liza haematochelia) (MuCuZnSOD) was structurally and functionally characterized to evaluate its antioxidant capacity, antibacterial properties, and protective level in various pathogenic stress conditions. Structural characteristics of MuCuZnSOD were evaluated using different bioinformatics tools. Pairwise sequence comparison and evolutionary tree structure revealed that the MuCuZnSOD sequence was closely related to the CuZnSOD sequence of Oplegnathus fasciatus with a 94.2% sequence identity. Sequence alignment analysis indicated that the CuZnSOD domain was well conserved. The highest transcriptional expression of MuCuZnSOD was identified in the blood. Immune challenge with lipopolysaccharide (LPS), Lactococcus garvieae, and polyinosinic-polycytidylic acid (poly I:C) exhibited an increased MuCuZnSOD mRNA expression in the blood and liver. Transfected green fluorescent protein-fused MuCuZnSOD was localized in the cytoplasm. Recombinant MuCuZnSOD (rMuCuZnSOD) was overexpressed in a bacterial system. The rMuCuZnSOD possessed significant antioxidant properties as determined by conventional xanthine oxidase assay. The optimum pH and temperature of rMuCuZnSOD were found to be pH 9 and 25 °C, respectively. rMuCuZnSOD enzyme activity increased in a concentration-dependent manner. Treatment with potassium cyanide highly inhibited the rMuCuZnSOD activity. rMuCuZnSOD possessed a significant peroxidation activity in the presence of HCO3- ions as demonstrated by the increased viability in cells treated with the enzyme in the presence of hydrogen peroxide. Antibacterial assays showed that rMuCuZnSOD had significant growth-inhibitory effects on both gram-positive and gram-negative bacteria. Collectively, our findings demonstrate that MuCuZnSOD is an essential antioxidant protein, which regulates the host defense mechanisms and innate immunity under oxidative stress.

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 effect of cinnamaldehyde (CM) enriched diet on immunity and cytokine gene expression in Channa striatus against Aphanomyces invadans is reported. C. striatus was uniformly divided into eight groups (n = 25 fish each) and fed with formulated diets with 0, 5, 10, and 15 mg kg-1 CM enriched diet. In healthy and infected groups fed with 5 mg kg-1 diet the leukocytes count increased significantly after 4th week; with 10 mg kg-1 CM diet the increase manifested after 6th week, but with 15 mg kg-1 not even after 8th week. In both groups, 5 mg kg-1 CM diet resulted in a significant increase in the serum total protein, albumin, and globulin levels after 4th week, whereas with other diets this effect was observed only after 6th week. Similarly, with any enriched diet the lysozyme activity increased significantly, but with 15 mg kg-1 CM diet only after 6th week. In both groups the complement activity and lymphocyte production increased significantly when fed with 5 mg kg-1 CM diet after 4th week while with other enriched diets only after 6th week. The phagocytic activity increased significantly in both groups fed with 5 mg kg-1 CM diet after 6th week, whereas the SOD activity increased after 4th week. The IgM production increased significantly in both groups fed with 5 mg kg-1 CM diet after 2nd week, while with 5 and 10 mg kg-1 CM diet after 4th week. In both groups, the expression of CXCR3α was significant on 4th week when fed with 10 mg kg-1 CM diet, while in the healthy group fed with 15 mg kg-1 CM diet the expression manifested earlier than 4th week. However, when fed with 10 and 15 mg kg-1 CM diets the increase was observed on 6th week; whereas, the expression of MHC-I reached the maximum on 6th week with any enriched diet. The results indicate that in C. striatus the innate immunity and expression of cytokine and immune related genes were significantly modulated when fed with 5 mg kg-1 CM diet on 4th week against A. invadans.

Abstract
Bactericidal permeability-increasing protein (BPI) and lipopolysaccharide (LPS) binding proteins (LBP) both play important roles in innate immunity against bacterial infection. Herein, we identified a novel full-length cDNA sequence of BPI/LBP from Trachidermus fasciatus (designated as TfBPI/LBP). The full-length cDNA sequence of TfBPI/LBP was 1594bp, which contains an open reading frame (ORF) of 1422bp encoding a secreted protein with 473 amino acid residues. Similar to BPI/LBPs from other teleost and mammals, the peptide of TfBPI/LBP contains an N-terminal BPI/LBP/CETP domain with an LPS-binding motif and a C-terminal BPI/LBP/CETP domain BPI2. Multiple alignments and phylogenetic analysis supported that TfBPI/LBP was a new member of the vertebrate BPI/LBP family. TfBPI/LBP gene was ubiquitously expressed in all detected tissues, with the most abundant in the liver, and could be significantly induced in the skin, blood, liver, spleen post LPS challenge. The recombinant N-terminal domain of TfBPI/LBP (designated as rTfBPI/LBPN) was successfully expressed in Escherichia coli. Sugar binding assay showed that rTfBPI/LBPN could bind to LPS, peptidoglycan (PGN), and lipoteichoic acid (LTA), with the highest affinity to LPS. The results of bacteria binding and agglutinating assay revealed that rTfBPI/LBPN could bind and agglutinate to all of the 9 kinds of bacteria we used. Moreover, membrane integrity analysis indicated that rTfBPI/LBPN could increase the membrane permeability of bacteria. These results suggested that BPI/LBP may play crucial roles in host defense against microorganisms, possibly through non-selective bacterial recognition and induction of membrane penetration.

Abstract
Pattern recognition receptors (PRRs) are a class of immune sensors that play crucial roles in detecting and responding to the conserved patterns of microorganisms. To date, many PRRs, such as TLRs, RLRs and NLRs, as well as their downstream molecules have been identified and characterized in teleost, while their ligands and immunoregulatory mechanisms remain largely unknown. In the present review, we described and discussed the main members of TLR/RLR/NLR families, including their expression profiles, signaling transductions and functions in teleost. And some splicing isoforms from TLR/RLR/NLR families were also addressed, which play synergistic and/or antagonistic roles in response to pathogen infections in teleost. TLRs sense different pathogens by forming homodimer and/or heterodimer. Beyond, functions of TLRs can also be affected by migrating. And some endolysosomal TLRs undergo proteolytic cleavage and in a pH-dependent mechanism to attain a mature functional form that mediate ligand recognition and downstream signaling. Until now, more than 80 members in TLR/RLR/NLR families have been identified in teleost, while only TLR5, TLR9, TLR19, TLR21, TLR22, MDA5, LGP2, NOD1 and NOD2 have direct evidence of ligand recognition in teleost. Meanwhile, new ligands as well as signaling pathways do occur during evolution of teleost. This review summarizes progresses on the TLRs/RLRs/NLRs in teleost. We attempt to insight into the ligands recognition and signaling transmission of TLRs/RLRs/NLRs in teleost.

Abstract
Biologically active compounds used in agriculture that develop near aquatic environments easily spill into rivers or lakes. As a result, insecticides, herbicides and fungicides are observed worldwide in aquatic environments and accumulated in aquatic organism. Many insecticides, including organochlorine and organophosphate, have long been banned long ago because of their high persistence and non-target toxicity. However, previous studies have shown that persistent pesticides remain in aquatic organisms. The immune system is the first defense mechanism against exposure to persistent organic pollutants or pesticides that have been released into the aquatic environment. Many insecticides have been reported to cause immunotoxicity, which is represented by alteration of phagocytic and lysozyme activity. Recent studies show that immunotoxicity by insecticides exerts a more complex mechanism in fish. Insecticides induce immunotoxic effects, such as the release of inflammatory cytokines from head kidney macrophages and inhibition of immune cell proliferation in fish, which can lead to death in severe cases. Even currently used pesticides, such as pyrethroid, with low bioaccumulation have been shown to induce immunotoxicological effects in fish when exposed continuously. Therefore, this review describes the types and bioaccumulation of insecticides that cause immunotoxicity and detailed immunotoxicological mechanisms in fish tissues.

Abstract
The objective of this study was to analyze the efficiency of the killed vaccine against nervous necrosis virus on Acipenser stellutus. Heat inactivated VNN vaccine was administrated in 7 g juveniles of Acipenser stellutus as a laboratory model and it was included in three different adjuvants that were used as injection and immersion forms with different doses. Ten groups consisting of 30 A. stellutus fish in each group (group 1-4 with 3 replications, others with no replicate) were divided totally into 18 aquariums. Two steps of vaccination were done with a one-month interval and after that, all treatments and control groups were challenged by the virulent VNN virus. The mortality rate of immersion and injection groups were 12.9% and 19.8% respectively, compared to 100% mortality in the control group. Histopathology and immunohistochemistry findings were evaluated. According to the mortality rate one month after challenging, a low range mortality of 12.5% was seen in group 2 with no pathological lesion and negative IHC test in the brain and eye tissues, whereas 100% of the control group (unvaccinated group) died with severe vacuolation in the brain and eye tissues and also positive IHC test. The correlation assay between these results concluded that the immersion form with 75% of aquatic-specific Montanide IMS 1312 Seppic adjuvant made better immunization with no pathological sign or forming the complex of antigen-antibody in IHC assay. These findings are important because of the impossibility of injection in the larval stage and also due to the occurrence of the disease in the first stage of sturgeon life which could cause high mortality in susceptible fish in the larval stage.

Abstract
The impact of anthropogenic contaminants on the immune system of fishes is an issue of growing concern. An important xenobiotic receptor that mediates effects of chemicals, such as halogenated aromatic hydrocarbons (HAHs) and polyaromatic hydrocarbons (PAHs), is the aryl hydrocarbon receptor (AhR). Fish toxicological research has focused on the role of this receptor in xenobiotic biotransformation as well as in causing developmental, cardiac, and reproductive toxicity. However, biomedical research has unraveled an important physiological role of the AhR in the immune system, what suggests that this receptor could be involved in immunotoxic effects of environmental contaminants. The aims of the present review are to critically discuss the available knowledge on (i) the expression and possible function of the AhR in the immune systems of teleost fishes; and (ii) the impact of AhR-activating xenobiotics on the immune systems of fish at the levels of immune gene expression, immune cell proliferation and immune cell function, immune pathology, and resistance to infectious disease. The existing information indicates that the AhR is expressed in the fish immune system, but currently, we have little understanding of its physiological role. Exposure to AhR-activating contaminants results in the modulation of numerous immune structural and functional parameters of fish. Despite the diversity of fish species studied and the experimental conditions investigated, the published findings rather uniformly point to immunosuppressive actions of xenobiotic AhR ligands in fish. These effects are often associated with increased disease susceptibility. The fact that fish populations from HAH- and PAH-contaminated environments suffer immune disturbances and elevated disease susceptibility highlights that the immunotoxic effects of AhR-activating xenobiotics bear environmental relevance.

Abstract
Bacterial diseases represent the main impediment to the development of fish aquaculture. Granulomatous diseases caused by bacteria lead to fish culture losses by high mortality rates and slow growth. Bacteria belonging to genera Streptococcus spp., Mycobacterium sp., Nocardia sp., Francisella sp., and Staphylococcus sp. have been implicated in the development of granulomatous processes. The granuloma formation and the fish's immune response continue to be the subject of scientific research. In fish, the first defense line is constituted by non-specific humoral factors through growth-inhibiting substances such as transferrin and antiproteases, or lytic effectors as lysozyme and antimicrobial peptides, and linking with non-specific phagocyte responses. If the first line is breached, fish produce antibody constituents for a specific humoral defense inhibiting bacterial adherence, as well as the mobilization of non-phagocytic host cells and counteracting toxins from bacteria. However, bacteria causing granulomatous diseases can be persistent microorganisms, difficult to eliminate that can cause chronic diseases, even using some immune system components to survive. Understanding the infectious process leading to granulomatosis and how the host's immune system responds against granulomatous diseases is crucial to know more about fish immunology and develop strategies to overcome granulomatous diseases.

Abstract
Thioredoxin domain-containing protein 17 (TXNDC17) is an important, highly conserved oxidoreductase protein, ubiquitously expressed in all living organisms. It is a small (~14 kDa) protein mostly co-expressed with thioredoxin 1 (TRx1). In the present study, we obtained the TXNDC17 gene sequence from a previously constructed yellowtail clownfish (Amphiprion clarkii) (AcTXNDC17) database and studied its phylogeny as well as the protein's molecular characteristics, antioxidant, and antiapoptotic effects. The full length of the AcTXNDC17 cDNA sequence was 862 bp with a 372 bp region encoding a 123 amino acid (aa) protein. The predicted molecular mass and isoelectric point of AcTXNDC17 were 14.2 kDa and 5.75, respectively. AcTXNDC17 contained a TRX-related protein 14 domain and a highly conserved N-terminal Cys43-Pro44-Asp45-Cys46 motif. qPCR analysis revealed that AcTXNDC17 transcripts were ubiquitously and differently expressed in all the examined tissues. AcTXNDC17 expression in the spleen tissue was significantly upregulated in a time-dependent manner upon stimulation with lipopolysaccharide (LPS), polyinosinic-polycytidylic (poly I:C), and Vibrio harveyi. Besides, LPS-induced intrinsic apoptotic pathway (TNF-α, caspase-8, Bid, cytochrome C, caspase-9, and caspase-3) gene expression was significantly lower in AcTXNDC17-overexpressing RAW264.7 cells, as were NF-κB activation and nitric oxide (NO) production. Furthermore, the viability of H2O2-stimulated macrophages was significantly improved under AcTXNDC17 overexpression. Collectively, our findings indicate that AcTXNDC17 is involved in the innate immune response of the yellowtail clownfish.

Abstract
Immunological memory can be regarded as the key aspect of adaptive immunity, i.e. a specific response to first contact with an antigen, which in mammals is determined by the properties of T, B and NK cells. Re-exposure to the same antigen results in a more rapid response of the activated specific cells, which have a unique property that is the immunological memory acquired upon first contact with the antigen. Such a state of immune activity is also to be understood as related to "altered behavior of the immune system" due to genetic alterations, presumably maintained independently of the antigen. It also indicates a possible alternative mechanism of maintaining the immune state at a low level of the immune response, "directed" by an antigen or dependent on an antigen, associated with repeated exposure to the same antigen from time to time, as well as the concept of innate immune memory, associated with epigenetic reprogramming of myeloid cells, i.e. macrophages and NK cells. Studies on Teleostei have provided evidence for the presence of immunological memory determined by T and B cells and a secondary response stronger than the primary response. Research has also demonstrated that in these animals macrophages and NK-like cells (similar to mammalian NK cells) are able to respond when re-exposed to the same antigen. Regardless of previous reports on immunological memory in teleost fish, many reactions and mechanisms related to this ability require further investigation. The very nature of immunological memory and the activity of cells involved in this process, in particular macrophages and NK-like cells, need to be explained. This paper presents problems associated with adaptive and innate immune memory in teleost fish and characteristics of cells associated with this ability.

Abstract
The aquaculture industry's rapid growth to meet commercial demand can trigger an outbreak of infectious diseases due to high-density farming. Antibiotic overuse and misuse in fish farming and its global health consequences have led to searching for more natural alternatives such as medicinal plants. In this sense, garlic (Allium sativum) has different bioactive compounds with biological properties for animal health. Among them are the ajoene, alliin, and allicin, which confer biological properties such as growth promotion, antimicrobial, antiviral, antioxidant, and antiparasitic. Ways to use garlic in aquaculture include oil, fresh mash, aqueous extract, and garlic powder. The powder presentation is the most used in aquaculture; it is generally applied by oral administration, adding to the feed, and the dose used ranges from 0.05 to 40 g/kg of feed. Garlic has been used in the aquaculture of different species such as rainbow trout (Oncorhynchus mykiss), spotted grouper (Epinephelus coioides), catfish (Clarias gariepinus), tilapia (Oreochromis niloticus), guppy fish (Poecilia reticulata), goldfish (Carassius auratus), and barramundi (Lates calcarifer). In addition to its properties, garlic's usage became popular, thanks to its low cost, easy incorporation into food, and little environmental impact. Therefore, its application can be an effective solution to combat diseases, improve organisms' health using natural supplies, and as an alternative to antibiotics. This review reports and discusses plant-derived products' beneficial properties, emphasizing garlic and its usages in fish aquaculture.

Abstract
Toll-like receptors (TLRs), as a family of pattern recognition receptors (PRRs), possess specific pathogen-related molecular pattern (PAMP) recognition spectrum in inducing immune responses. In this study, sixteen TLRs were identified and characterized in mandarin fish (Siniperca chuatsi). All these TLRs consist of leucine-rich repeats (LRRs), a transmembrane domain and a Toll/interleukin-I receptor (TIR) domain, with the exception of TLR5S which lacks TIR domain, and they can be clustered into five branches, i.e. TLR1 subfamily, TLR3 subfamily, TLR5 subfamily, TLR7 subfamily and TLR11 subfamily in phylogenetic tree. These TLR genes were expressed in all tested tissues and had high expression levels in immune-related tissues such as head-kidney and spleen or mucosa-related tissues such as intestine and pyloric caecum. The transcripts of TLR2a, TLR2b, TLR3, TLR13a, TLR14, TLR22 and TLR23 were all significantly up-regulated after stimulation with poly(I:C); TLR1, TLR2a, TLR2b, TLR3, TLR5M, TLR5S, TLR13a and TLR13b transcripts were all significantly up-regulated after stimulation with PGN; and TLR2a, TLR2b, TLR5M, TLR5S, TLR7, TLR8, TLR9, TLR13c, TLR14 and TLR22 transcripts were all significantly up-regulated after stimulation with LPS in isolated head kidney lymphocytes of mandarin fish. The findings in this study may provide a valuable basis for functional study on TLR genes in mandarin fish.

Abstract
Immunoglobulins (Igs) are complex glycoproteins that play critical functions in innate and adaptive immunity of all jawed vertebrates. Given the unique characteristics of mucosal barriers, secretory Igs (sIgs) have specialized to maintain homeostasis and keep pathogens at bay at mucosal tissues from fish to mammals. In teleost fish, the three main IgH isotypes, IgM, IgD and IgT/Z can be found in different proportions at the mucosal secretions of the skin, gills, gut, nasal, buccal, and pharyngeal mucosae. Similar to the role of mammalian IgA, IgT plays a predominant role in fish mucosal immunity. Recent studies in IgT have illuminated the primordial role of sIgs in both microbiota homeostasis and pathogen control at mucosal sites. Ten years ago, IgT was discovered to be an immunoglobulin class specialized in mucosal immunity. Aiming at this 10-year anniversary, the goal of this review is to summarize the current status of the field of fish Igs since that discovery, while identifying knowledge gaps and future avenues that will move the field forward in both basic and applied science areas.

Abstract
IL-22, a multifunctional cytokine, acts as an important regulator in host immunity in mammals. IL-22 homologues have been characterized in several species of fish, with its expression found in multiple tissues/cells in fish, but its target cells have not been fully analyzed. In the present research, different organ/tissue isolated cells were examined for the expression of IL-22 and the induced IL-22 responses in mandarin fish. The mandarin fish IL-22 was found to be expressed in all these tested cells with high basal expression in intestinal cells. The HKLs showed low basal expression but significant increase in expression of IL-22 after LPS treatment or bacterial infection. Only intestinal cells showed response to IL-22 by enhanced expression of hepcidin, LEAP2 and IL-22BP, with unresponsiveness observed in other tested cells, which indicated the cell-specificity of IL-22 bioactivity in mandarin fish. One of the heterodimeric receptor components for IL-22, the IL-22RA1, was cloned in mandarin fish, with four tandem fibronectin type III (FNIII) domains identified in its extracellular part. IL-22RA1 exhibited an intestinal cell-specific expression pattern, although another receptor component of IL-22, IL-10R2, displayed constitutive expressions in all these tested cells. The present study reveals that the mandarin fish IL-22 exhibits its bioactivity in a cell-specific manner in intestinal cells, which is reflected in the restrictive expression of its receptor unit, IL-22RA1.

Abstract
Galectins are protein that participates in a variety of immune responses in the process of pathogenic infections. In the present study, a chimera galectin gene was screened from the transcriptome database of Nibea albiflora, which was named as YdGal-3. The results of qRT-PCR showed that the mRNA transcripts of YdGal-3 were ubiquitously distributed in all the detected tissues. After infection with Vibrio harveyi, the expression of YdGal-3 in liver, spleen, and head kidney increased significantly. Immunohistochemistry showed that YdGal-3 protein was widely expressed in the head kidney. The purified YdGal-3 protein by prokaryotic expression agglutinated red blood cells. Sugar inhibition assay showed that the agglutinating activity of YdGal-3 protein was inhibited by different sugars including lactose, D-galactose, and lipopolysaccharide. In addition, we mutated YdGal-3 His 294 into proline (P), alanine (A), glycine (G), and aspartic acid (D), it was further proved that the residue plays a key role in agglutination. YdGal-3 agglutinated some gram-negative bacteria including Pseudomonas plecoglossicida, Vibrio parahemolyticus, V. harveyi, and Aeromonas hydrophila, and exhibited antibacterial activity. These results suggested that YdGal-3 protein played an important role in the innate immunity of N. albiflora.

Abstract
The pharmacokinetics of levamisole were determined in the belugas after single intravascular (IV), and single and multiple-dose oral by feed administrations. Also, the effect of levamisole (LVM) on the stress and immune responses of belugas were assessed. One hundred-fourteen healthy belugas in 4 different groups received single LVM administration at the doses of 50 and 100 mg/kg via IV and oral routes. A separate group of 24 belugas were administered oral LVM at the dose of 100 mg/kg for 5 days. Blood samples were collected at different time points after administrations to measure plasma concentrations of LVM by a validated high-performance liquid chromatography (HPLC) assay. For immunological evaluations, a total of 126 belugas received 50 and 100 mg/kg LVM via medicated feed for 5 days or served as the control without any medication; blood samples were recovered on day 0, 1, 3, 5, 7, 10, and 14 to measure hemolytic activity of the complement system (HAC50), serum lysozyme activity, serum antibacterial activity, glucose, cortisol, total protein, albumin and C3 contents. In the single-dose administration, quantified LVM concentrations were dose-dependent and the oral bioavailability was in the range of 43.2-49.6%. In the multiple-dose administration, the peak plasma concentration at the steady state was 45.2 mg/ml, and accumulation ratio was calculated as 3.6. In the immunological study, LVM especially at the dose of 100 mg/kg increased HAC50, lysozyme and antibacterial activity in the sera of treated fish. No significant effect of LVM on glucose and albumin content was observed, but cortisol levels decreased and C3 content was increased, more significantly by LVM at the dose of 100 mg/kg. Our results indicate that LVM is well absorbed after oral administration and reached to concentrations that can affect stress indicators and improve immune responses in belugas.

Abstract
The regulation of C/N in aquaculture water is an important means of environmental regulation, of which the most common is bioflocs technology (BFT). Here, an eight-week feeding experiment and a lipopolysaccharide (LPS) challenge test were proceed to investigate the growth, oxidative stress, immunosuppression and GR-NF-κB related genes expression of Channa argus rearing in the BFT. Four groups were set, the control group was a basic diet (C/N = 7.6:1), and the other three groups were adjusted by glucose, which was C/N 10: 1, C/N 15: 1 and C/N 20:1, respectively. And we detected the two-stage test indexes of C. argus before and after the LPS challenge. The results showed that the bioflocs of C/N 15:1 group significantly (P < 0.05) promoted the growth performance. Similarly, the trend of immune enzyme activity was the same before and after LPS challenge, but decreased after challenge (except AKP and IgM). The best group is still treatment C/N 15:1. Liver and intestine SOD, CAT, GPX, ASA and T-AOC levels of juveniles in treatment C/N 15:1 were markedly increased (P < 0.05) compared to control before and after the LPS challenge. Simultaneously, the content of MDA in control group was considerably higher than that in treatment C/N 15:1 (P < 0.05). Furthermore, C/N 15:1 group significantly down-regulated the expression level of pro-inflammatory factors (NF-κB, TNF-α, IL-1β and IL-8), and up-regulated IκBα, GR, HSP70 and HSP90 expression levels considerably (P < 0.05). Also, intestinal morphology appeared injury in control group, while intestinal integrity was better in treatment C/N 10:1 and C/N 15:1 after challenge. Taken together, these upshot indicated that bioflocs could enhance growth and alleviate C. argus from LPS-induced oxidative stress, immunosuppression and inflammation through restraining GR-NF-κB signaling pathway. The best C/N ratio for alleviating LPS is 15:1.

Abstract
Aquaculture growth will unavoidably involve the implementation of innovative and sustainable production strategies, being functional feeds among the most promising ones. A wide spectrum of phytogenics, particularly those containing terpenes and organosulfur compounds, are increasingly studied in aquafeeds, due to their growth promoting, antimicrobial, immunostimulant, antioxidant, anti-inflammatory and sedative properties. This trend relies on the importance of the mucosal barrier in the fish defense. Establishing the phytogenics' mode of action in mucosal tissues is of importance for further use and safe administration. Although the impact of phytogenics upon fish mucosal immunity has been extensively approached, most of the studies fail in addressing the mechanisms underlying their pharmacological effects. Unstandardized testing as an extended practice also questions the reproducibility and safety of such studies, limiting the use of phytogenics at commercial scale. The information presented herein provides insight on the fish mucosal immune responses to phytogenics, suggesting their mode of action, and ultimately encouraging the practice of reliable and reproducible research for novel feed additives for aquafeeds. For proper screening, characterization and optimization of their mode of action, we encourage the evaluation of purified compounds using in vitro systems before moving forward to in vivo trials. The formulation of additives with combinations of compounds previously characterized is recommended to avoid bacterial resistance. To improve the delivery of phytogenics and overcome limitations associated to compounds volatility and susceptibility to degradation, the use of encapsulation is advisable. Besides, newer approaches and dedicated methodologies are needed to elucidate the phytogenics pharmacokinetics and mode of action in depth.

Abstract
MicroRNAs (miRNAs) are a class of highly conserved, endogenous non-coding single-stranded small RNA molecules with a length of 18-25 nucleotides. MiRNAs can negatively regulate the target gene through complementary pairing with the mRNA. It has been more than 20 years since the discovery of miRNA molecules, and many achievements have been made in fish research. This paper reviews the research progress in the regulation of fish nutrition and immunity by miRNAs in recent years. MiRNAs regulate the synthesis of long-chain polyunsaturated fatty acids, and are involved in the metabolism of glucose, lipids, as well as cholesterol in fish. Moreover, miRNAs play various roles in antibacterial and antiviral immunity of fish. They can promote the immune response of fish, but may also participate in the immune escape mechanism of bacteria or viruses. One important aspect of miRNAs regulation on fish immunity is mediated by targeting pattern recognition receptors and downstream signaling factors. Together, current results indicate that miRNAs are widely involved in the complex regulatory network of fish. Further studies on fish miRNAs may deepen our understanding of the regulatory network of fish nutrition and immunity, and have the potential to promote the development of microRNA-based products and detection reagents that can be applied in aquaculture industry.

Abstract
Catalase, a key enzyme in the antioxidant defense grid of organisms, scavenges free radicals to curtail their harmful effects on the host, supporting proper immune function. Herein, we report the identification and characterization of a catalase homolog from Amphiprion clarkii (ClCat), followed by its functional characterization. An open reading frame was identified in the cDNA sequence of ClCat at 1581 bp, which encodes a protein of 527 amino acids (aa) with a molecular mass of 60 kDa. In silico analyses of ClCat revealed characteristic features of the catalase family and a lack of a signal peptide. Multiple sequence alignment of ClCat indicated the conservation of functionally important residues among its homologs. According to phylogenetic analysis, ClCat was of vertebrate origin, positioned within the teleost clade. During native conditions, ClCat mRNA was highly expressed in blood, followed by the liver and kidney. Moreover, significant changes in ClCat transcription were observed after stimulation with LPS, poly I:C, and Vibrio harveyi, in a time-dependent manner. Recombinant ClCat (rClCat) was characterized, and its peroxidase activity was determined. Furthermore, the optimum temperature and pH for rClCat were determined to be 30-40 °C and pH 7, respectively. Oxidative stress tolerance and chromatin condensation assays indicated enhanced cell survival and reduced apoptosis, resulting from reactive oxygen species scavenging by rClCat. The DNA-protective function of rClCat was further confirmed via a metal-catalyzed oxidation assay. Taken together, our findings propose that rClCat plays an essential role in maintaining cellular oxidative homeostasis and host immune protection.

Abstract
At each stage of innate immune response, there are stimulatory and inhibitory signals that modulate the strength and character of the response. RIG-I-like receptor (RLR) signaling pathway plays pivotal roles in antiviral innate immune response. Recent studies have revealed the molecular mechanisms that viral infection leads to the activation of RLRs-mediated downstream signaling cascades and the production of type I interferons (IFNs). However, antiviral immune responses must be tightly regulated in order to prevent detrimental type I IFNs production. Previous reviews have highlighted negative regulation of RLR signaling pathway, which mainly target to directly regulate RIG-I, MDA5, MAVS and TBK1 function in mammals. In this review, we summarize recent advances in our understanding of negative regulators of RLR signaling pathway in teleost, with specific focus on piscine and viral regulatory mechanisms that directly or indirectly inhibit the function of RIG-I, MDA5, LGP2, MAVS, TRAF3, TBK1, IRF3 and IRF7 both in the steady state or upon viral infection. We also further discuss important directions for future studies, especially for non-coding RNAs and post-translational modifications via fish specific TRIM proteins. The knowledge of negative regulators of RLR signaling pathway in teleost will shed new light on the critical information for potential therapeutic purposes.

Abstract
Sulfated polysaccharides (SPs) derived from Codium fragile (sponge seaweed) can regulate cytokine expression in mammalian macrophages, NK cell lines and olive flounder head kidney primary cells in vitro. In this study, we found that SPs from C. fragile exhibited anti-bacterial activities against fish pathogenic bacteria including Streptococcus parauberis, Lactococcus garvieae, Aeromonas salmonicida and Edwardsiella tarda at a minimum inhibitory concentration of 2 mg/mL, but not against S. iniae or Vibrio anguillarum. Immunostimulatory effects of SPs from C. fragile on rockfish (Sebastes schlegelii) were evaluated by analyzing mRNA expression levels of inflammatory cytokines (interleukin (IL)-1β, IL-8, IL-6 and tumor necrosis factor (TNF)-α) and anti-inflammatory cytokines (IL-10) both in vitro and in vivo. Results revealed that expression levels of all genes tested were upregulated in rockfish head kidney and spleen cells by SPs from C. fragile in a dose/time-dependent manner in vitro. By contrast, expression levels of these genes were significantly (p < 0.05) downregulated in the head kidney and spleen of rockfish in vivo at 1 and 3 days post intraperitoneal injection of SPs from C. fragile. In the liver, these genes were downregulated on day 1, but upregulated on day 3. Treatment with SPs downregulated the expression of these genes in spleen, but upregulated IL-10 gene expression in the intestine and liver. Meanwhile, when fish were fed with crude SPs for 4 weeks and challenged with E. tarda, infected fish started to die starting from 2 days after immune challenge. The cumulative mortality of the 0.1% group was significantly lower (p < 0.05) than that of the control group without feeding with SPs. Expression levels of IL-1β and IL-6 genes were significantly (p < 0.05) upregulated in head kidney of the 0.5% group on day 1 while IL-1β gene expression was downregulated on day 3 in the liver. These results indicate that SPs from C. fragile can regulate the immune gene expression in rockfish and that a diet containing 0.1% crude SPs can reduce the mortality of rockfish caused by E. tarda infection.

Abstract
Larval lake sturgeon, Acipenser fulvescens, reared in hatcheries for stock enhancement of wild populations may be susceptible to early opportunistic bacterial infection. Thus, we examined survival and whole-body mRNA expression of both stress- and immune-related genes (MyD88, IL-1β, StAR, GR1, and HSP70) in 30 days post fertilization larval lake sturgeon following immune challenge with lipopolysaccharides (LPS). Larval sturgeon were exposed to 0, 25, 50, 100, 150, and 200 μg ml-1 LPS and sampled after 30 min, 4 h, and 48 h. Mortality was zero in 0 and 25 μg ml-1 LPS; 37.5% in 50 μg ml-1 LPS and 100% in the higher concentrations. Expression of MyD88 and StAR mRNA were positively correlated and increased with time in the 50 μg ml-1 LPS treatment. There was an influence of both treatment and time on IL-1β mRNA, with expression 10-fold higher than controls after 4 h. Expression of HSP70 mRNA was suppressed within 30 min of 50 μg ml-1 LPS exposure and remained so throughout the time course. Correlated mRNA expression of GR1 with MyD88, StAR and IL-1β suggests a potential relationship between the innate immune and glucocorticoid responses of larval lake sturgeon during this early developmental stage. Data presented suggest that larval lake sturgeon largely responded with predicted changes in gene expression of immune related and stress response genes following LPS challenge. This study provides a foundation for future research examining the effects of hatchery and naturally occurring stressors on the immune responses of larval lake sturgeon.

Abstract
CXCL14 is a chemokine which is orthologous in mammals and fish. CXCL14 has a functional role in different organs, with immunomodulatory functions in mammals, but its expression and function in fish is not well known. Moreover, it shows no effects related to immunity in the central nervous system or the reproductive tract in diverse species. Black rockfish (Sebastes schlegelii) is an economically important fish in Asian countries, whose CXCL14 expression pattern is yet to be understood. In this study, the homology of the CXCL14 amino acid sequence in S. schlegelii was compared with that in other species, including fish. Moreover, in situ hybridization analysis revealed that it was highly expressed in the brain and ovary of S. schlegelii. Taken together, we identified for the first time, the cell-specific expression of CXCL14 in S. schlegelii.

Abstract
A 10-week feeding trial was run to investigate the separate and simultaneous effects of exogenous enzymes (Enz), probiotics (Pro), and Pro-Enz mixtures on the hematology indices, serum biochemical parameters, and innate-immunity status of juvenile Siberian sturgeon. The fish (138.06 ± 3.64 g) were randomly dispersed into 12 tanks (20 individuals per tank) and fed with Enz (Phytase, protease, and xylanase), Pro (Pediococcus pentosaceus and Lactococcus lactis), and Pro-Enz cocktail. At the end of the feeding bioassay, the highest values of red blood cell count, hemoglobin concentration, hematocrit level, and lymphocyte percentage followed by the lowest neutrophil percentage were obtained in Pro-Enz treatment (P < 0.05). Despite a significantly lower level of alkaline phosphatase in the fish fed with Pro supplemented diet (P < 0.05), no significant difference was found in the serum level of alanine aminotransferase and aspartate aminotransferase among the experimental groups (P > 0.05). Total protein content was significantly upregulated in serum and skin mucus samples from those fed with supplemented diets compared to the control group (P < 0.05). In both serum and skin mucus samples, higher immune responses in terms of lysozyme activity, immunoglobulin M, total protein was seen in Pro-Enz treatment compared to the control group followed by the serum complement components (P < 0.05). The results indicate that the combinational supplementation of Siberian sturgeon diet with the exogenous enzymes and probiotics modulates the physiometabolic responses and innate immune system to a higher grade than their individual supplementation.

Abstract
Monogeneans parasitise mainly the outer structures of fish, such as the gills, fins, and skin, that is, tissues covered with a mucous layer. While attached by sclerotised structures to host's surface, monogeneans feed on its blood or epidermal cells and mucus. Besides being a rich source of nutrients, these tissues also contain humoral immune factors and immune cells, which are ready to launch defence mechanisms against the tegument or gastrointestinal tract of these invaders. The exploitation of hosts' resources by the Monogenea must, therefore, be accompanied by suppressive and immunomodulatory mechanisms which protect the parasites against attacks by host immune system. Elimination of hosts' cytotoxic molecules and evasion of host immune response is often mediated by proteins secreted by the parasites. The aim of this review is to summarise existing knowledge on fish immune responses against monogeneans. Results gleaned from experimental infections illustrate the various interactions between parasites and the innate and adaptive immune system of the fish. The involvement of monogenean molecules (mainly inhibitors of peptidases) in molecular communication with host immune system is discussed.

Abstract
Probiotics have been defined as live microorganisms that when administered in adequate amounts confer health benefits to the host. The use of probiotics in aquaculture is an attractive bio-friendly method to decrease the impact of infectious diseases, but is still not an extended practice. Although many studies have investigated the systemic and mucosal immunological effects of probiotics, not all of them have established whether they were actually capable of increasing resistance to different types of pathogens, being this the outmost desired goal. In this sense, in the current paper, we have summarized those experiments in which probiotics were shown to provide increased resistance against bacterial, viral or parasitic pathogens. Additionally, we have reviewed what is known for fish probiotics regarding the mechanisms through which they exert positive effects on pathogen resistance, including direct actions on the pathogen, as well as positive effects on the host.

Abstract
Acetylcholine (Ach) is the main neurotransmitter in the neuronal cholinergic system and also works as a signaling molecule in non-neuronal cells and tissues. The diversity of signaling pathways mediated by Ach provides a basis for understanding the biology of the cholinergic epithelial cells and immune cells in the gill of the species studied. NECs in the gill were not found surprisingly, but specialized cells showing the morphological, histochemical and ultrastructural characteristics of eosinophils were located in the gill filaments and respiratory lamellae. Much remains unknown about the interaction between the nerves and eosinophils that modulate both the release of acetylcholine and its nicotinic and muscarinic receptors including the role of acetylcholine in the mechanisms of O2 chemosensing. In this study we report for the first time the expression of Ach in the pavement cells of the gill lamellae in fish, the mast cells associated with eosinophils and nerve interaction for both immune cell types, in the gill of the extant butterfly fish Pantodon buchholzi. Multiple roles have been hypothesized for Ach and alpha nAChR in the gills. Among these there are the possible involvement of the pavement cells of the gill lamellae as O2 chemosensitive cells, the interaction of Ach positive mast cells with eosinophils and interaction of eosinophils with nerve terminals. This could be related to the use of the vesicular acetylcholine transporter (VAChT) and the alpha 2 subunit of the acetylcholine nicotinic receptor (alpha 2 nAChR). These data demonstrate the presence of Ach multiple sites of neuronal and non-neuronal release and reception within the gill and its ancestral signaling that arose during the evolutionary history of this conservative fish species.

Abstract
Toll-like receptors (TLRs)are pattern recognition receptors (PRRs) that are important in invertebrate innate immunity for the recognition and elimination of pathogens. Although they were reported in many fishes, Toll-like receptors subfamily contain a large number of members with different functions that need to research in deep. In the present study, the full-length cDNA of TLR3 from the golden pompano, Trachinotus ovatus, was cloned and characterized. The full length of ToTLR3 cDNA was 3710 bp including an open reading frame of 2760 bp encoding a peptide of 919 amino acids. The derived amino acids sequence comprised of 14 leucine-rich repeats (LRR), capped with LRRCT followed by transmembrane domain and cytoplasmic Toll/IL-1R domain (TIR). Multiple sequence alignment and phylogenetic analysis revealed that ToTLR3 shared the highest similarity to the teleost fish and suggested ToTLR3 is fairly conservative in evolution process. Tissues distribution analysis indicated that ToTLR3 showed a tissue-specific variation with high expression in blood and liver. After the fish were stimulated by poly(I:C), flagellin and LPS, ToTLR3 expression in the liver, intestine, blood, kidney, skin and muscle was significantly upregulated in a time-depended manner, especially in immune related tissues such as liver, blood and kidney. Binding assay revealed the specificity of rToTLR3 for pathogen-associated molecular patterns (PAMPs) and bacteria that included Vibrio harveyi, V. vulnificus, V. anguillarum, Photobacterium damselae, Escherichia coli, Aeromonas hydrophila, Staphylococcus aureus and PolyI:C, LPS, Flagellin, and PGN. In addition, a luciferase reporter assay showed that overexpression ToTLR3 significantly increased NF-κB activity. Collectively, our results suggested that ToTLR3 might play an important role as a pattern recognition receptor (PRR) in the immune response towards pathogen infections, and transmiss the danger signal to downstream signaling pathways.

Abstract
Vibrio harveyi is regarded as serious pathogen for marine fishes. However, host defense mechanisms involved in V. harveyi infection remain incompletely defined. The transcription factor IFN regulatory factor 7 (IRF7) is largely associated with host defense against viral infections, and the role of IRF7 during V. harveyi infection in fish has not been well illuminated previously. In this study, IRF7 from golden pompano (Trachinotus ovatus) was characterized (TroIRF7). The TroIRF7 gene is 1323 bp, which encodes 440 amino acid residues. Multiple amino acid alignments of TroIRF7 shows 30.37%-80.18% identity with other fish IRF7s, including Epinephelus coioides (80.18%), Larimichthys crocea (79.72%), Collichthys lucidus (79.26%), Miichthys miiuy (79.26%), Channa argus (78.77%), Cynoglossus semilaevis (72.67%), and Gadus morhua (65.23%). Like other IRF7s, TroIRF7 also contains 3 conserved domains: an N-terminal DNA-binding domain (DBD), an IRF association domain (IAD), and a C-terminal serine-rich domain (SRD). In the DBD, 4-5 conserved tryptophans were observed, which is a characteristic unique to all fish IRF7 members. TroIRF7 was constitutively expressed, with high levels in gill, head kidney, spleen, skin, and intestine. V. harveyi infection-induced TroIRF7 transcripts significantly up-regulation and translocation to the nucleus. TroIRF7 overexpression promote the fish to inhibit the replication of V. harveyi. And TroIRF7 knockdown led to decreased bacterial clearance in fish tissue. Furthermore, over-expression of TroIRF7 resulted in an increased production of interferon a3 and IFN signaling molecule in the spleen, suggesting that V. harveyi activates the IRF7- IFN pathway. These results suggest that TroIRF7 is an important component of immune responses against V. harveyi infection.

Abstract
The stat gene family diversified during early vertebrate evolution thanks to two rounds of whole genome duplication (WGD) to produce a typical repertoire composed of 6 STAT factors (named 1-6). In contrast, only one or two stat genes have been reported in C. elegans and in D. melanogaster. The main types of STAT found from bony fish to mammals are present in Agnathan genomes, but a typical STAT1-6 repertoire is only observed in jawed vertebrates. Comparative syntenies showed that STAT6 was the closest to the ancestor of the family. An extensive survey of stat genes across fish including polyploid species showed that whole genome duplications did not lead to a uniform expansion of stat genes. While 2 to 5 stat1 are present in salmonids, whose genome duplicated about 35My ago, only one copy of stat2 and stat6 is retained. In contrast, common carp, with a recent whole genome duplication (5-10My), possesses a doubled stat repertoire indicating that the elimination of stat2 and stat6 additional copies is not immediate. Altogether our data shed light on the multiplicity of evolutionary pathways followed by key components of the canonical cytokine receptor signalling pathway, and point to differential selective constraints exerted on these factors.
