Abstract
Tumour necrosis factor (TNF) receptor-associated factor (TRAF) is a receptor protein that has important functions in the immune system. Nonetheless, there have been few reports of traf genes in teleost fishes. The present study aimed to identify the traf genes from the genomic information of yellow catfish (Pelteobagrus fulvidraco). Eight traf genes were identified and named, which are distributed on different chromosomes but have similar conserved protein domains. Phylogenetic and syntenic analyses demonstrated conservation of traf genes during evolution. In addition, yellow catfish has the relatively rare traf1 and traf5 genes. Gene structure and motif analysis revealed the homology and distribution diversity of the traf genes. Quantitative real-time reverse transcription PCR was used to study the expression patterns of traf genes in healthy fish tissues and after infection by Aeromonas hydrophila. The results demonstrated significant changes in traf gene expression, indicating a potential role in innate immunity.

Abstract
Tumor necrosis factor receptor-associated factors (TRAFs) are signaling mediators for Toll-like receptor (TLR) and tumor necrosis factor (TNFR) superfamily that play important roles in organism immune response. However, reports on systematic identification of TRAF gene family in teleost fish and the function of TRAFs in innate immunity of black rockfish (Sebastes schlegelii) are lacked. In our study, eight TRAF genes were identified and characterized, namely, SsTRAF2a, SsTRAF2a-like, SsTRAF2b, SsTRAF3, SsTRAF4, SsTRAF5, SsTRAF6 and SsTRAF7 in S. schegelii. Furthermore, we analyzed their sequences, conserved domains, gene structures, motif compositions, phylogeny, tissue expression patterns in healthy and Vibro. anguillarum challenged individuals. All the SsTRAFs contained typical conserved domain, including C-terminal MATH domain and N-terminal RING finger domain. Analyses of gene structures and motifs showed the distribution of exon-intron and conserved motifs in S. schegelii and serval other teleost fish. We also analyzed the expression file of SsTRAFs in five immune-relate organs, liver, spleen, kidney, gill and intestine in healthy and bacterial challenged fish. The results indicated that all SsTRAF member were widely involved in immune response after pathogenic bacteria infection. In summary, the analyses of TRAFs in S. schegelii will be helpful to better understand the diverse roles of TRAF genes in the innate immune response to bacterial challenge.

Abstract
Toll/IL-1R domain-containing adaptor-inducing IFN-β (TRIF), tumor necrosis factor receptor-associated factor 6 (TRAF6) and TANK-binding kinase 1 (TBK1) are critical signal transducers in toll-like receptors (TLRs) signaling pathway. In the present study, TRIF, TRAF6 and TBK1 were characterized from golden pompano (Trachinotus ovatus), named as TroTRIF, TroTRAF6 and TroTBK1, respectively. The full cDNA length of TroTRIF, TroTRAF6 and TroTBK1 was 2297 bp, 2293 bp, and 2482 bp, which respectively encoded 589, 573 and 723 amino acids. The deduced amino acids sequences of TroTRIF, TroTRAF6 and TroTBK1 contained conserved motifs, similar to their counterparts in other vertebrates. Phylogenetic tree analysis revealed that TroTRIF, TroTRAF6 and TroTBK1 were well clustered with their counterparts in other fish species. Quantitative Real-Time PCR (qPCR) analysis showed that TroTRIF, TroTBK1 and TroTRAF6 were detected in all examined tissues of healthy fish, but shared distinct transcript levels. Moreover, the expressions of TroTRIF, TroTBK1 and TroTRAF6 were generally induced by polyriboinosinic-polyribocytidylic acid (polyI:C), lipopolysaccharide (LPS), and Vibrio alginolyticus stimulation in vivo, indicating their critical roles in the immune defense of golden pompano against pathogen invasion. Our results provide valuable information for understanding the functions of these genes in golden pompano.

Front Immunol 2022; 13:944528. [PMID: 35898509 PMCID: PMC9310645 DOI: 10.3389/fimmu.2022.944528] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Accepted: 06/13/2022] [Indexed: 11/19/2022] Open
Abstract
Tumor necrosis factor receptor-associated factors (TRAFs) are important adaptor molecules that play important roles in host immune regulation and inflammatory responses. Compared to other members of TRAFs, the function of TRAF4 in vertebrate immunity remains unclear, especially in teleosts. In the present study, TRAF4 ortholog was cloned and identified in large yellow croaker (Larimichthys crocea), named as Lc-TRAF4. The open reading frame (ORF) of Lc-TRAF4 is 1,413 bp and encodes a protein of 470 amino acids (aa), which is consisted of a RING finger domain, two zinc finger domains, and a MATH domain. The genome organization of Lc-TRAF4 is conserved in teleosts, amphibians, birds, and mammals, with 7 exons and 6 introns. Quantitative real-time PCR analysis revealed that Lc-TRAF4 was broadly distributed in various organs/tissues of healthy large yellow croakers and could be significantly up-regulated in the gill, intestine, spleen, head kidney, and blood under poly I:C, LPS, PGN, and Pseudomonas plecoglossicida stimulations. Notably, luciferase assays showed that overexpression of Lc-TRAF4 could significantly induce the activation of IRF3, IRF7, and type I IFN promoters, with the RING finger and zinc finger domains function importantly in such promoter activation. Confocal microscopy revealed that Lc-TRAF4 is located in the cytoplasm, whereas the deletion of the RING finger, zinc finger or MATH domain showed little effect on the subcellular localization of Lc-TRAF4. Interestingly, Lc-TRAF4 overexpression could significantly enhance Lc-TRIF and Lc-TRAF6 medicated IRF3 and IRF7 promoter activation. In addition, co-expression of Lc-TRAF4 with Lc-TRIF or Lc-TRAF6 could significantly induce the expression of antiviral and inflammation-related genes, including IRF3, IRF7, ISG15, ISG56, Mx, RSAD2, TNF-α, and IL-1β compared to the only overexpression of Lc-TRAF4, Lc-TRIF or Lc-TRAF6. These results collectively imply that Lc-TRAF4 functions as an enhancer in Lc-TRIF and Lc-TRAF6 mediated antiviral and inflammatory signaling.

Abstract
Tumor necrosis factor (TNF) receptor-associated factors (TRAFs) are major signal transducers for the TNF and interleukin-1/Toll-like receptor superfamilies that transduce signals from various immune receptors. To investigate the interaction of TRAF3 and other proteins in signaling pathways and to identify its antiviral function in teleosts, we cloned and characterized a TRAF3 homolog from orange-spotted grouper (Epinephelus coioides) (EcTRAF3). The open reading frame of EcTRAF3 consists of 1767 base pairs encoding a 588 amino acid protein, and the predicted molecular mass is 66.71 kDa EcTRAF3 shares 99.83% identity with TRAF3 of Epinephelus lanceolatus. Expression analysis revealed that EcTRAF3 was broadly distributed in examined tissues and was up-regulated under polyinosinic-polycytidylic acid and red-spotted grouper nervous necrosis virus (RGNNV) stimulation in vivo. EcTRAF3 was identified as a cytosolic protein based on fluorescence microscopy analysis. Overexpression of EcTRAF3 inhibited RGNNV replication in grouper spleen cells, and it interacted with the coat protein of RGNNV. Overexpression of EcTRAF3 also induced the activation of interferon β (IFN-β), IFN-stimulated response element (ISRE), and nuclear factor-κB (NF-κB). EcTRAF3 co-transfected with Stimulator of Interferon Genes (STING) of grouper (EcSTING) induced a significantly higher level of IFN-β promoter activity. Moreover, EcTRAF3 interacted with EcSTING, implying that EcTRAF3 may function as an enhancer in EcSTING-mediated signaling. Taken together, our results suggest that EcTRAF3 negatively regulates the RGNNV-induced cellular antiviral response and plays an important role in the immune response system of fish.

Abstract
In the present study, we characterized tumor necrosis factor receptor-associated factor 2/7 (lcTRAF2/7) and TNFR1-associated death domain protein (lcTRADD) in Larimichthys crocea (L. crocea) and examined their expression profiles in tissues of Vibrio-challenged and unchallenged fish. The coding sequences of lcTRAF2, lcTRAF7, and lcTRADD were 1488, 2454, and 744 nucleotides, and they encoded proteins of 495, 344, and 248 amino acids, respectively. The results of phylogenetic analysis revealed that lcTRAF2, lcTRAF7, and lcTRADD were closest to Oplegnathus fasciatus (85%), Xiphophorus maculatus (97%), and Acanthochromis polyacanthus (65%), respectively. Multiple sequence alignment showed that lcTRAF2 and lcTRAF7 were highly conserved with other vertebrate TRAFs in their functional domains; however, lcTRADD was poorly conserved. The results of quantitative real-time polymerase chain reaction analysis indicated that lcTRAF2, lcTRAF7, and lcTRADD were constitutively expressed in the spleen, liver, kidney, heart, brain, gill, bladder, skin, fin, eye, and muscle. After challenging fish with Vibrio parahaemolyticus, the mRNA expression levels of lcTRAF2, lcTRAF7, and lcTRADD were upregulated in liver, spleen, and kidney. Immunofluorescence staining revealed that lcTRAF2 and lcTRADD were cytoplasmic in localization, whereas lcTRAF7 targeted both the cytoplasm and nucleus. In addition, the NF-κB protein level was upregulated after lipopolysaccharide stimulation in lcTRAF2, lcTRAF7, or lcTRADD overexpressing cells. Taken collectively, these results have improved our understanding of the functions of TRAF2, TRAF7, and TRADD in pathogenic infections in teleosts.

Abstract
TNFR-associated factors (TRAFs) and receptor-interacting protein kinases (RIPKs) are important immunological linker molecules in mammals and play important roles in the TNFα, TLR and IFN signaling pathways. However, the evolutionary origins of these genes in vertebrates have not previously been described in lampreys. In this study, we searched the genomes of Lampetra japonicum, Lethenteron reissneri, and Petromyzon marinus for genes encoding trafs and ripks and performed homologous sequence alignment, phylogenetic tree, functional domain, conserved motif, gene structure, and synteny analyses to determine their evolutionary relationships. The distribution of the lamprey traf and ripk families and the immune response of the gene families in lampreys stimulated by different pathogens were also demonstrated, suggesting a role of structural changes in expression and functional diversification. Additionally, the dual luciferase reporter gene assay showed that the addition of exogenous immunomodulator (TNFα or IFN) to the overexpression of LjLRIPK1a or LjTRAF3/6 significantly downregulated NF-κB or ISRE activation. LjRIPK1a can significantly enhance caspase-8 activity, and overexpression of LjRIPK1a or LjTRAF3a/6 in HEK293T cells results in cell apoptosis. In summary, this study makes an important contribution to the understanding of the traf and ripk gene families in different vertebrates. Our results also provide new evidence for the evolution of vertebrate TRAFs and RIPKs and their impacts on immune regulation.

Abstract
Tumor necrosis factor (TNF) receptor-associated factors (TRAFs) play crucial roles as signaling mediators for the TNF receptor (TNFR) superfamily and the interleukin-1 receptor/Toll-like receptor (IL-1R/TLR) superfamily. TRAFs collectively play important roles in multiple biological processes and organismal immunity. However, systematic identification of the TRAF gene family in teleost fish has not yet been reported, and there is little available information about its roles in innate immunity in Chinese tongue sole (Cynoglossus semilaevis), an aquaculture fish of high economic value. In the present study, we identified and characterized seven TRAF genes, namely, CsTRAF2a, CsTRAF2b, CsTRAF3, CsTRAF4, CsTRAF5, CsTRAF6 and CsTRAF7, in Chinese tongue sole, and the complete ORFs of the CsTRAFs were cloned. Sequence analysis revealed various genomic structures of the CsTRAFs and showed that they contain typical conserved domains compared with mammalian TRAFs. Phylogenetic analysis indicated the evolutionary relationships of TRAF family members in teleost fish and revealed an absence of TRAF1 in most species and TRAF5 in some species of teleosts. Analysis of the gene structures and motifs showed the diversity and distribution of exon-intron structures and conserved motifs in Chinese tongue sole and several other teleost species. Real-time quantitative PCR was used to investigate the expression patterns of CsTRAF genes in tissues of healthy fish and in the gills, livers and spleens of fish after bacterial infection with Vibrio harveyi. The results indicate that only CsTRAF2a is relatively highly expressed in the brain and that the other CsTRAFs are highly expressed in immune-related tissues and may participate in the immune response after infection with pathogenic bacteria. Functional analysis of CsTRAF3, CsTRAF4 and CsTRAF6 revealed that only CsTRAF6 could strongly activate the NF-кB pathway after overexpression of CsTRAF3, CsTRAF4 and CsTRAF6 in HEK-293T cells. This systematic analysis provided valuable information about the diverse roles of TRAFs in the innate immune response to pathogenic bacterial infection in teleost fish and will contribute to the functional characterization of CsTRAF genes in further research.

Abstract
In this study, we cloned the complementary (c)DNA sequences of tumour necrosis factor receptor (TNFR)-associated factor 3 (traf3) in Nile tilapia, Oreochromis niloticus. The expression patterns of the traf3 gene were investigated and preliminary functional analyses were performed. In healthy fish, traf3 transcript was broadly expressed in all examined tissues, with the highest expression level in the blood and the lowest in the liver. The traf3 gene reached its highest expression at 8 days post-fertilisation (dpf) during embryonic development. Moreover, we found that expression of traf3 was clearly altered following stimulation with Streptococcus agalactiae in vivo and that traf3 could be induced by lipopolysaccharides (LPS), Poly I: C and S. agalactiae WC1535 in Nile tilapia macrophages. Overexpression in 293T cells showed that Traf3 protein was mainly distributed in the cytoplasm and could significantly increase nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) activation. Taken together, these results implied that traf3 could play important roles in the immune response to pathogen invasion.

FISH & SHELLFISH IMMUNOLOGY 2019; 93:781-788.

Abstract
Nile tilapia (Oreochromis niloticus) is a pivotal economic fish that has been plagued by Streptococcus infections. Tumor necrosis factor receptor-associated factor 5 (TRAF5) is a crucial adaptor molecule, which can trigger downstream signaling cascades involved in immune pathway. In this study, Nile tilapia TRAF5 coding sequence (named OnTRAF5) was obtained, which contained typical functional domains, such as RING, zinc finger, coiled-coil and MATH domain. Different from other TRAF molecules, OnTRAF5 had shown relatively low identify with its homolog, and it was clustered into other teleost TRAF5 proteins. qRT-PCR was used to analysis the expression level of OnTRAF5 in gill, skin, muscle, head kidney, heart, intestine, thymus, liver, spleen and brain, In healthy Nile tilapia, the expression level of OnTRAF5 in intestine, gill and spleen were significantly higher than other tissues. While under Streptococcus agalactiae infection, the expression level of OnTRAF5 was improved significantly in all detected organs. Additionally, over-expression WT OnTRAF5 activated NF-κB, deletion of RING or zinc finger caused the activity impaired. In conclusion, OnTRAF5 participate in anti-bacteria immune response and is crucial for the signaling transduction.
