Differential tissue immune stimulation through immersion in bacterial and viral agonists in the Antarctic Notothenia rossii. FISH & SHELLFISH IMMUNOLOGY 2024; 148:109516.

Abstract
The genome evolution of Antarctic notothenioids has been modulated by their extreme environment over millennia and more recently by human-caused constraints such as overfishing and climate change. Here we investigated the characteristics of the immune system in Notothenia rossii and how it responds to 8 h immersion in viral (Poly I:C, polyinosinic: polycytidylic acid) and bacterial (LPS, lipopolysaccharide) proxies. Blood plasma antiprotease activity and haematocrit were reduced in Poly I:C-treated fish only, while plasma protein, lysozyme activity and cortisol were unchanged with both treatments. The skin and duodenum transcriptomes responded strongly to the treatments, unlike the liver and spleen which had a mild response. Furthermore, the skin transcriptome responded most to the bacterial proxy (cell adhesion, metabolism and immune response processes) and the duodenum (metabolism, response to stress, regulation of intracellular signal transduction, and immune system responses) to the viral proxy. The differential tissue response to the two proxy challenges is indicative of immune specialisation of the duodenum and the skin towards pathogens. NOD-like and C-type lectin receptors may be central in recognising LPS and Poly I:C. Other antimicrobial compounds such as iron and selenium-related genes are essential defence mechanisms to protect the host from sepsis. In conclusion, our study revealed a specific response of two immune barrier tissue, the skin and duodenum, in Notothenia rossii when exposed to pathogen proxies by immersion, and this may represent an adaptation to pathogen infective strategies.

Ramírez-Calero S, Paula JR, Otjacques E, Ravasi T, Rosa R, Schunter C. Neuromolecular responses in disrupted mutualistic cleaning interactions under future environmental conditions. BMC Biol 2023; 21:258. [PMID: 37957664 PMCID: PMC10644551 DOI: 10.1186/s12915-023-01761-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Accepted: 11/03/2023] [Indexed: 11/15/2023] Open
Abstract
BACKGROUND Mutualistic interactions, which constitute some of the most advantageous interactions among fish species, are highly vulnerable to environmental changes. A key mutualistic interaction is the cleaning service rendered by the cleaner wrasse, Labroides dimidiatus, which involves intricate processes of social behaviour to remove ectoparasites from client fish and can be altered in near-future environmental conditions. Here, we evaluated the neuromolecular mechanisms behind the behavioural disruption of cleaning interactions in response to future environments. We subjected cleaner wrasses and surgeonfish (Acanthurus leucosternon, serving as clients) to elevated temperature (warming, 32 °C), increased levels of CO2 (high CO2, 1000 ppm), and a combined condition of elevated CO2 and temperature (warming and high CO2, 32 °C, and 1000 ppm) for 28 days. RESULTS Each of these conditions resulted in behavioural disruptions concerning the motivation to interact and the quality of interaction (high CO2 - 80.7%, warming - 92.6%, warming and high CO2 - 79.5%, p < 0.001). Using transcriptomics of the fore-, mid-, and hindbrain, we discovered that most transcriptional reprogramming in both species under warming conditions occurred primarily in the hind- and forebrain. The associated functions under warming were linked to stress, heat shock proteins, hypoxia, and behaviour. In contrast, elevated CO2 exposure affected a range of functions associated with GABA, behaviour, visual perception, thyroid hormones and circadian rhythm. Interestingly, in the combined warming and high CO2 condition, we did not observe any expression changes of behaviour. However, we did find signs of endoplasmic reticulum stress and apoptosis, suggesting not only an additive effect of the environmental conditions but also a trade-off between physiological performance and behaviour in the cleaner wrasse. CONCLUSIONS We show that impending environmental shifts can affect the behaviour and molecular processes that sustain mutualistic interactions between L. dimidiatus and its clients, which could have a cascading effect on their adaptation potential and possibly cause large-scale impacts on coral reef ecosystems.

Abstract
Meagre (Argyrosomus regius) belongs to the family Sciaenidae and is a promising candidate for Mediterranean aquaculture diversification. As a relatively recent species in aquaculture, the physiological consequences of the immune system activation in meagre are understudied. Spleen, as a primary lymphoid organ has an essential role in meagre immune and inflammatory responses. In this study, we have evaluated the in vivo effects of lipopolysaccharide (LPS) on the spleen transcriptome of meagre by RNA-seq analysis at 4 and 24 h after injection.

Abstract
Toll-like receptors (TLRs) recognize conserved pathogen-associated molecular patterns (PAMPs) and are an ancient and well-conserved group of pattern recognition receptors (PRRs). The isolation of the Antarctic continent and its unique teleost fish and microbiota prompted the present investigation into Tlr evolution. Gene homologues of tlr members in teleosts from temperate regions were present in the genome of Antarctic Nototheniidae and the non-Antarctic sister lineage Bovichtidae. Overall, in Nototheniidae apart from D. mawsoni, no major tlr gene family expansion or contraction occurred. Instead, lineage and species-specific changes in the ectodomain and LRR of Tlrs occurred, particularly in the Tlr11 superfamily that is well represented in fish. Positive selective pressure and associated sequence modifications in the TLR ectodomain and within the leucine-rich repeats (LRR), important for pathogen recognition, occurred in Tlr5, Tlr8, Tlr13, Tlr21, Tlr22, and Tlr23 presumably associated with the unique Antarctic microbiota. Exposure to lipopolysaccharide (Escherichia coli O111:B4) Gram negative bacteria did not modify tlr gene expression in N. rossii head–kidney or anterior intestine, although increased water temperature (+4°C) had a significant effect.

Abstract
This study isolated CFI gene from Pelteobagrus fulvidraco and named it PfCFI. The cDNA of PfCFI is 2374 bp long, including a 52 bp 5' untranslated sequence, a 222 bp 3' untranslated sequence, and an open reading frame (ORF) of 2100 bp encoding polypeptide consisting of 699 amino acids. Phylogenetic analysis revealed that the PfCFI was closely related to CFI of Ictalurus punctatus. Real-time quantitative reverse transcription-PCR (qRT-PCR) analysis indicate that there is the PfCFI gene which expressed in all the rest of tested tissues in varied levels, and mainly distributed in liver and least in heart. The reseachers induce the expressions level of PfCFI gene in liver, spleen, head kidney and blood at different points in time after challenged with lipopolysaccharide (LPS), and polyriboinosinic polyribocytidylic acid (poly I:C), respectively. Together these results suggested that CFI gene plays an important role in resistance to pathogens in yellow catfish immunity.

Abstract
Quantitative proteomics via mass spectrometry can provide valuable insight into molecular and phenotypic characteristics of a living system. Recent mass spectrometry developments include data‐independent acquisition (SWATH/DIA‐MS), an accurate, sensitive and reproducible method for analysing the whole proteome. The main requirement for this method is the creation of a comprehensive spectral library. New technologies have emerged producing larger and more accurate species‐specific libraries leading to a progressive collection of proteome references for multiple molecular model species. Here, for the first time, we set out to compare different spectral library constructions using multiple tissues from a coral reef fish to demonstrate its value and feasibility for nonmodel organisms. We created a large spectral library composed of 12,553 protein groups from liver and brain tissues. Via identification of differentially expressed proteins under fish exposure to elevated pCO2 and temperature, we validated the application and usefulness of these different spectral libraries. Successful identification of significant differentially expressed proteins from different environmental exposures occurred using the library with a combination of data‐independent and data‐dependent acquisition methods as well as both tissue types. Further analysis revealed expected patterns of significantly up‐regulated heat shock proteins in a dual condition of ocean warming and acidification indicating the biological accuracy and relevance of the method. This study provides the first reference spectral library for a nonmodel organism. It represents a useful guide for future building of accurate spectral library references in nonmodel organisms allowing the discovery of ecologically relevant changes in the proteome.

Abstract
Dendritic cells (DCs) have a strong ability to stimulate naive T lymphocyte proliferation, so DCs play an important regulatory role in the initiation of the specific immune response. DCs cannot play the role of antigen presentation without the expression of surface molecules. The chemokine receptor CCR7 and the costimulatory molecules CD80/86 and CD83 are not only markers of DC maturation but also important functional molecules in the immune response of DC-T cells. In this study, partial cDNA sequences of CCR7, CD80/86 and CD83 were obtained by rapid amplification of cDNA ends (RACE) technology from yellow catfish. Bioinformatics analysis of deduced amino acid sequences of these three genes showed that CCR7, CD80/86 and CD83 genes in yellow catfish have similar functional domains to the homologs in other vertebrates, which indicated that the functions of these genes may be somewhat conserved during the evolution process. Afterward, the expression characteristics of these three genes in different tissues were detected by q-PCR. This result indicated that CCR7, CD80/86 and CD83 were expressed in all examined tissues, and the highest expression levels of CCR7 and CD80/86 and CD83 were detected in the trunk kidney, muscle and midgut, respectively. Meanwhile, the expression levels of CCR7 and CD80/86 were lowest in the gill, and the expression of CD83 was lowest in the stomach. Finally, healthy yellow catfish were infected with A.hydrophila (1.0 × 107 CFU/mL) or E.ictaluri (1.0 × 106 CFU/mL), q-PCR results indicated that both pathogenic bacteria can induce significant upregulation of CCR7, CD80/86 and CD83 in immune organs, and the expression levels of these genes in the intestine were higher than those in the skin and gill. Our results in this study provide a molecular basis for exploring the role of CCR7, CD80/86 and CD83 in the immune responses induced by bacteria, and can help us to understand the difference of immune responses induced by extracellular and intracellular bacteria.

Abstract
Mitogen-activated protein kinases (MAPK) and nuclear factor kappa B (NF-κB) pathways are considered to be two crucial intracellular signaling cascades in pro-inflammatory responses. In this study, we reported the coding sequences (CDS) of MAPKp38 and NF-κBp65 from yellow catfish. We also investigated the gene structure, expression patterns and functional role in yellow catfish. The CDS of MAPKp38 is 1,086 bp encoding 361 amino acids (AA). The MAPKp38 protein has a long highly conserved serine/threonine protein kinases catalytic domain. The NF-κBp65 CDS is 1,794 bp, and the gene encodes 597 AA, with a Rel homology domain (RHD) which consists of a RHD-DNA-binding domain and an Ig-like, plexins, transcription factors (IPT) domain. Moreover, MAPKp38 and NF-κBp65 protein of bony fish and other vertebrates have a single clade. Quantitative real-time PCR analysis revealed the presence of the MAPKp38 and NF-κBp65 transcript in 12 tissues of healthy yellow catfish. The highest expression levels of MAPKp38 and NF-κBp65 were detected in the heart and liver, respectively. Upon stimulation with an intraperitoneal injection of lipopolysaccharide (LPS), the expression levels of MAPKp38 and NF-κBp65 were up-regulated in the intestine. These results indicated that MAPKp38 and NF-κBp65 play important roles in mediating the response protection against LPS in yellow catfish.

A non-mammalian Toll-like receptor 26 (TLR26)gene mediates innate immune responses in yellow catfish Pelteobagrus fulvidraco. FISH & SHELLFISH IMMUNOLOGY 2019; 95:491-497. [PMID: 31689551 DOI: 10.1016/j.fsi.2019.11.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/22/2019] [Revised: 10/24/2019] [Accepted: 11/01/2019] [Indexed: 06/10/2023]
Abstract
In this study, we identified a fish-specific Toll-like receptor (TLR) in Pelteobagrus fulvidraco, an economically important freshwater fish in China. This TLR, PfTLR26, was shown to be encoded by a 3084 bp open reading frame (ORF), producing a polypeptide 1027 amino acids in length. The PfTLR26 protein contains a signal peptide, eight leucine-rich repeat (LRR) domains, two LRR_TYP domains in the extracellular region, and a Toll/interleukin (IL)-1 receptor (TIR) domain in the cytoplasmic region, consistent with the characteristic TLR domain architecture. This predicted 117.1 kDa protein was highly homologous to those of other fish, with phylogenetic analysis revealing the closest relation to TLR26 of Ictalurus punctatus. Real-time quantitative reverse transcription-PCR (qRT-PCR) analysis showed that the PfTLR26 gene was expressed in all tissues tested, with the highest expression levels seen in the head kidney and blood, and the lowest seen in muscle. PfTLR26 exhibited significant upregulation in liver, spleen, head kidney, and blood at different time points following challenge with the common TLR agonists lipopolysaccharide (LPS) and polyriboinosinic polyribocytidylic acid (Poly I:C). Taken together, these results suggest that PfTLR26 may be an important component of the P. fulvidraco innate immune system, participating in the transduction of TLR signaling under pathogen stimulation.

Molecular identification and expression analysis of natural resistance-associated macrophage protein (Nramp) gene from yellow catfish Pelteobagrus fulvidraco (Siluriformes: Bagridae). Int J Biol Macromol 2019; 141:345-350. [PMID: 31491517 DOI: 10.1016/j.ijbiomac.2019.09.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2019] [Revised: 08/05/2019] [Accepted: 09/03/2019] [Indexed: 12/23/2022]
Abstract
Natural resistance associated macrophage protein genes (Nramp) is one of the important candidate genes responsible for regulating immune response against pathogen infection. The aim of the present was to quantify expression of Nramp gene in response to pathogen infection. Here, a Nramp was identified and molecularly characterized from Pelteobagrus fulvidraco (PfNramp). The obtained 3134 bp cDNA fragment of PfNramp comprised a 5'-untranslated region (UTR) of 81 bp, a 3'-UTR of 1403 bp and an open reading frame (ORF) of 1650 bp, encoding a polypeptide of 549 amino acids that contained a typical structural features of Nramp domain (Pfam01566). BLAST analysis exhibited that PfNramp shared sequence similarity to other organisms, in particular to Ictalurus furcatus (92%), Danio rerio (82%), and Homo sapiens (77%). Phylogenetic analysis revealed that PfNramp is close to Teleostei. Real-time quantitative reverse transcription-PCR (qRT-PCR) analysis showed that PfNramp was expressed in all examined tissues, with the highest abundance in liver. The mRNA expression of PfNramp was remarkably increased at different time points after lipopolysaccharide (LPS), and polyriboinosinic polyribocytidylic acid (poly I:C) challenge. These results suggest that PfNramp is an inducible protein in the innate immune reactions of P. fulvidraco and probably in other fish species.

Abstract
In the intensive culture systems, excessive feeding leads to ammonia accumulation, which results in lipid metabolism disorder. However, little information is available on the modulation of lipid metabolism in fish as affected by feeding frequency and ammonia stress. In this study, weight gain increased as feeding frequency increased from one to four times daily, but feed conversion ratio is opposite. The highest survival was found in ammonia group when fish was fed two times daily. Liver ammonia content increased as feeding frequency increased from one to four times daily, and the highest brain ammonia content was found when fish was fed four times daily. The highest liver 6-phospho-gluconate dehydrogenase (6PGD), fatty acid synthase (FAS), carnitine palmitoyltransferase (CPT), and lipoprotein lipase (LPL) contents were found in control group when fish was fed four times daily; in comparison, the highest liver 6PGD, FAS, CPT, and LPL contents were found in ammonia group when fish was fed two times daily. Liver 6PGD, FAS, CPT 1, SREBP-1, and PPARα mRNA expression in control group increased significantly as feeding frequency increased from one to four times daily, and the highest expression of 6PGD, G6PD, and FAS was observed in ammonia group when fish was fed two times daily. This study indicated that the optimal feeding frequency is two times daily when yellow catfish exposed to ammonia.

Abstract
In order to elucidate the influence of T lymphocytes subpopulations on B lymphocytes immune response, in this paper, CD4-1+, CD4-2+, CD8+ T lymphocytes and B lymphocytes responses to thymus-independent (TI) or thymus-dependent (TD) antigen plus immunosuppressant were investigated in flounder (Paralichthys olivaceus). The results showed that in LPS-immunized group, the percentages of CD4-1+, CD4-2+, CD8β+ T (PCD4-1+ T, PCD4-2+ T and PCD8β+ T) lymphocytes in peripheral blood leucocytes (PBLs) had no significant variations, the percentages of IgM+ B (PIgM+ B) lymphocytes and LPS-specific antibodies (LA) significantly increased and peaked at 3rd or 4th week post-injection; CsA had no inhibition on both T/B lymphocytes and LA; RaPa only suppressed the PIgM+ B lymphocytes and LA, and the inhibition maximum (Imax) were about 35% and 20%, respectively. In KLH-immunized group, the PCD4-1+, PCD4-2+ and PCD8β+ T lymphocytes significantly increased and peaked at 3rd or 5th day, successively the PIgM+ B lymphocytes and KLH-specific antibodies (KA) significantly increased to the peak at 5th week; the PCD4-1+, PCD4-2+ T and PIgM+ B lymphocytes and LA were inhibited significantly by both CsA and RaPa, and the Imax on them were 13%-33%, 11%-25%, 19%-34%, 22%-26%, respectively, while the PCD8β+ T lymphocytes showed no significant suppression. The results indicated that the suppression of PIgM+ B lymphocytes in KLH + CsA group was not directly derived from CsA, but due to the suppression of T lymphocytes, especially CD4+ T lymphocytes subpopulations. The results showed for the first time that, similar to higher vertebrates, T lymphocytes didn't respond to TI antigen, moreover, T lymphocyte subpopulations had a regulation on the immune response of B lymphocyte for TD antigen in flounder.

Abstract
Myeloid differentiation factor 88 (MyD88) is an adaptor protein of Toll-like receptor (TLR) signalling pathways that activates the innate immune system. Herein, MyD88 was identified in the economically important freshwater fish Pelteobagrus fulvidraco. The complete 2156 bp PfMyD88 cDNA includes a 147 bp 5'-untranslated region (UTR), a 1133 bp 3'-UTR, and an open reading frame (ORF) of 876 bp encoding a 291 residue protein containing Death and Toll/interleukin-1 receptor (TIR) domains. The deduced protein sequence shares 88.8%, 73.8% and 59.3% identity with orthologs in Ictalurus punctatus, Danio rerio and Homo sapiens, respectively. qRT-PCR revealed expression in all tested tissues, highest in trunk kidney, followed by spleen, and lowest in muscle. After challenge with lipopolysaccharide (LPS) or polyriboinosinic polyribocytidylic acid (Poly I:C), PfMyD88 expression was up-regulated in blood, liver, head kidney and spleen. Thus, PfMyD88 acts in innate immunity in P. fulvidraco.

Abstract
The yellow catfish, Pelteobagrus fulvidraco, has been recognized as an important freshwater aquaculture species in Eastern and Southeast Asia. To gain a better understanding of the immune response in P. fulvidraco, we analyzed its transcriptome following stimulation with lipopolysaccharide (LPS). Phosphate buffer saline (PBS) was used as control. Following assembly and annotation, 72,152 unigenes with an average length of 1090 bp were identified. A total of 370 differentially expressed genes (DEGs) in the P. fulvidraco were observed at 12 h post LPS treatment, including 197 up-regulated genes and 173 down-regulated genes. Clusters of Orthologous Groups of proteins (KOG/COG) annotation demonstrated that a total of 18,819 unigenes classified into 26 categories. Gene ontology (GO) analysis revealed 20 biological process subcategories, 7 cellular component subcategories and 20 molecular function subcategories. The Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis identified immune responses pathways. Quantitative reverse transcription polymerase chain reaction measured the expression of 18 genes involved in the immune response. CXCL2-like chemokine (CXCL2), goose-type lysozyme (LYZ G), and cathepsin K (CTSK) were significantly up-regulated. This study enriches the P. fulvidraco transcriptome database and provides insight into the immune response of P. fulvidraco against infection.

Abstract
The present study explored the possible preventive effects of dietary glutamate (Glu) on LPS-induced oxidative damage, mRNA expression changes of tight junction (TJ) and defensin proteins, inflammatory and apoptosis response signaling molecules in fish intestine. Young Jian carp were fed five diets supplemental graded levels of Glu (0, 4, 8, 16 and 32 g kg-1 diet) for 63 days. The results indicated that Glu supplementation depressed LPS induced the production of reactive oxygen species (ROS) and severe oxidative damage (lipid peroxidation and protein oxidation) in fish intestine, which was partially due to the increased glutathione (GSH) content and antioxidant enzyme activities including superoxide dismutase (SOD), glutathione peroxidase (GPX), glutathione-S-transferase (GST), and glutathione reductase (GR) (P < 0.05). Further investigations indicated that Glu supplementation caused elevation of those antioxidant enzyme activities are related to the up-regulation of corresponding antioxidant enzymes and the related signaling factor Nrf2 mRNA levels (P < 0.05). Meanwhile, Glu pre-treatment significantly suppressed LPS-induced COX-2 and inflammatory cytokines mRNA expression and down-regulated NF-κB p65 and MAPK p38 transcription. Furthermore, pre-treatment with Glu prevented LPS induced apoptosis-related gene expression (caspase 3 and 9, P < 0.05). Lastly, Glu supplementation also attenuated LPS induced intestinal barrier function-related gene TJ proteins (ZO-1, occludin1, claudin2, 3, and 7), β-defensin1 and 3 mRNA expressions decreasing (P < 0.05). Taken together, the present results showed Glu could attenuate LPS induced the oxidative damage by Nrf2 signal pathway and depress LPS induced inflammation response (cytokines, COX-2, NF-κB p65, and MAPK p38), apoptosis (caspase3 and 9), and barrier function (ZO-1, occludin1, claudin2, 3 and 7, and β-defensin 1 and 3)-related gene expression changes of fish intestine.

FISH & SHELLFISH IMMUNOLOGY 2017; 70:57-65.

Abstract
Amphioxus, a cephalochordate, is a key model animal for studying the evolution of vertebrate immunity. Recently, studies have revealed that microRNA (miRNA) expression profiles change significantly in the amphioxus gill after immune stimulation, but it remains largely unknown how gene expression responds to immune stress. Elucidating gene expression changes in the amphioxus gill will provide a deeper understanding of the evolution of gill immunity in vertebrates. Here, we used high-throughput RNA sequencing technology (RNA-seq) to conduct tag-based digital gene expression profiling (DGE) analyses of the gills of control Branchiostoma belcheri and of those exposed to the viral mimic, poly(I:C) (pIC). Six libraries were created for the control and treatment groups including three biological replicates per group. A total of 1999 differently expressed genes (DEGs) were obtained, with 571 and 1428 DEGs showing up- or down-regulation, respectively, in the treatment group. Enrichment analysis of gene ontology (GO) terms and pathways revealed that the DEGs were primarily related to immune and defense response, apoptosis, human disease, cancer, protein metabolism, enzyme activity, and regulatory processes. In addition, eight DEGs were randomly selected to validate the RNA-seq data using real-time quantitative PCR (qRT-PCR), and the results confirmed the accuracy of the RNA-seq approach. Next, we screened eight key responding genes to examine the dynamic changes in expression levels at different time points in more detail. The results indicated that expressions of TRADD, MARCH, RNF31, NF-κb, CYP450, TNFRSF6B, IFI and LECT1 were induced to participate in the antiviral response against pIC. This study provides a valuable resource for understanding the role of the amphioxus gill in antiviral immunity and the evolution of gill immunity in vertebrates.

Abstract
Amphioxus is the closest living proxy for exploring the evolutionary origin of the immune system in vertebrates. To understand the immune responses of amphioxus to lipopolysaccharide (LPS), 5 ribosomal RNA (rRNA)-depleted libraries of amphioxus were constructed, including one control (0 h) library and 4 treatment libraries at 6, 12, 24, and 48 h post-injection (hpi) with LPS. The transcriptome of Branchiostoma belcheri was analyzed using strand-specific RNA sequencing technology (RNA-seq). A total of 6161, 6665, 7969, and 6447 differentially expressed genes (DEGs) were detected at 6, 12, 24, and 48 hpi, respectively, compared with expression levels at 0 h. We identified amphioxus genes active during the acute-phase response to LPS at different time points after stimulation. Moreover, to better visualize the resolution phase of the immune process during immune response, we identified 6057 and 5235 DEGs at 48 hpi by comparing with 6 and 24 hpi, respectively. Through real-time quantitative PCR (qRT-PCR) analysis of 12 selected DEGs, we demonstrated the accuracy of the RNA-seq data in this study. Functional enrichment analysis of DEGs demonstrated that most terms were related to defense and immune responses, disease and infection, cell apoptosis, and metabolism and catalysis. Subsequently, we identified 1330, 485, 670, 911, and 1624 time-specific genes (TSGs) at 0, 6, 12, 24, and 48 hpi. Time-specific terms at each of 5 time points were primarily involved in development, immune signaling, signal transduction, DNA repair and stability, and metabolism and catalysis, respectively. As this is the first study to report the transcriptome of an organism with primitive immunity following LPS challenge at multiple time points, it provides gene expression information for further research into the evolution of immunity in vertebrates.

Abstract
Atrazine (ATZ) and its main metabolites, i.e., diaminochlorotriazine (DACT), deisopropylatrazine (DIP), and deethylatrazine (DE), have been widely detected in surface water around the world. In the present study, to determine their immunotoxic effects, zebrafish during the early developmental stage were exposed to ATZ and its main metabolites at environmental concentrations (30, 100, 300 μg L-1). It was observed that ATZ, DACT, DIP and DE selectively induced the transcription of immunotoxic related genes including Tnfα, Il-1β, Il-6, Il-8, Cxcl-clc and Cc-chem in larval zebrafish. Pretreatment with ATZ and its metabolites also changed the immune response of larval zebrafish to LPS and E. coli challenge, which was indicated by the alternation in the mRNA levels of some cytokines. In addition, 300 μg L-1 ATZ and DACT exposure could also increase the release of tryptase into water, indicating that they increased the anaphylactoid reaction in the larval zebrafish. According to these results, both of ATZ and its metabolites exposure could cause the immunotoxicity in larval zebrafish. Thus, we thought that the ecological risks of the metabolites of ATZ on aquatic organisms could not be ignored.

Abstract
Hepcidin is a small, cysteine-rich antimicrobial peptide with a highly conserved β-sheet structure that plays a vital role in innate host immunity against pathogenic organisms. In this study, a hepcidin gene was identified in Pelteobagrus fulvidraco, an economically important freshwater fish in China. The gene is named PfHep. The complete PfHep cDNA was 723 bp, including a 5'-untranslated region (UTR) of 102 bp, a 3'-UTR of 339 bp and an open reading frame of 282 bp encoding a polypeptide of 93 amino acids, which includes a predicted signal peptide and the Hepcidin domain. The predicted mature, cationic PfHep protein has a typical hepcidin RX (K/R)R motif and eight conserved cysteine residues. The deduced PfHep protein sequence has 70%, 54% and 39% percent identity with hepcidins from Ictalurus punctatus, Danio rerio, and Homo sapiens, respectively. The predicted tertiary structure of PfHep is very similar to that of hepcidin in other animals. Phylogenetic analysis revealed that PfHep is closely related to the hepcidins of I. punctatus and I. furcatus. Real-time quantitative reverse transcription-PCR showed that the PfHep gene was expressed most in liver of healthy P. fulvidraco, and expressed to some extent in all the tissues tested. After challenge with lipopolysaccharide and polyriboinosinic:polyribocytidylic acid (poly I:C), respectively, the expression levels of PfHep were markedly upregulated in liver, spleen, head kidney and blood at different time points. Together these results imply that PfHep may be an important component of the innate immune system and be involved in immune defense against invading pathogens.

Abstract
Lysozymes, innate immunity molecules, play a vital role in immune response to pathogens. The yellow catfish Pelteobagrus fulvidraco (Siluriformes: Bagridae) is an economically important fish in China. The aim of this study was to quantify expression of the P. fulvidraco LysG gene (a g-type lysozyme) in response to pathogen-associated molecular patterns (PAMP) challenge. First, the P. fulvidraco LysG gene (PfLysG) was cloned and characterized. The full-length cDNA of PfLysG is 1323 bp, including a 5'-untranslated region (UTR) of 131 bp, a 3'-UTR of 634 bp, and an open reading frame of 558 bp encoding a polypeptide of 185 amino acids, which contains a transglycosylase SLT domain (Pfam01464). The predicted molecular weight of the protein is 20.52 kDa with a pI of 9.08. Two catalytic residues and seven N-acetyl-D-glucosamine binding sites are conserved in the sequence and there is no predicted signal peptide. The deduced PfLysG protein sequence has 84%, 76% and 69% percent identity with the LysGs from Ictalurus furcatus, Danio rerio, and Salmo salar, respectively. The predicted tertiary structure of PfLysG is very similar to that from other animals. Phylogenetic analysis showed that PfLysG is closely related to those from Teleostei. Real-time quantitative reverse transcription-PCR (qPCR) analysis showed that PfLysG was expressed in all examined tissues and most highly expressed in head kidney, spleen, and intestine. After simulated pathogen challenge with lipopolysaccharide and polyriboinosinic polyribocytidylic acid, respectively, the mRNA expression of PfLysG was upregulated significantly at different time points. The results suggest that the identified g-type lysozyme of P. fulvidraco is involved in innate immune responses.
