    ABSTRACT: Rac1, a Rho GTPase, serves critical immunological functions in mammals. Here, a Rac1 homolog (gcRac1) was identified in grass carp (Ctenopharyngodon idella). The full-length 2023-base pair gcRac1 cDNA contained a 579-bp open reading frame encoding a 192-residue protein, including a conserved RHO domain and nuclear localization signal. The gcRac1 protein shares high identity with other Rac1 counterparts and phylogenetically clustered with Danio rerio Rac1. The gcRac1 transcript showed wide tissue distribution and was inducible by Aeromonas hydrophila in vivo and in vitro; its expression also fluctuated with LPS or flagellin stimulation in vitro. With gcRac1 over-expression, gcPAK1, gcIL1-β, gcTNF-α and gcIFN were basically up-regulated by A. hydrophila and bacterial PAMPs induction, while gcRac1 knockdown decreased these transcripts after A. hydrophila challenge. Over-expression of gcRac1 reduced, while its suppression facilitated, bacterial invasion. Moreover, gcRac1 could activate NF-κB signaling. These findings implicate the vital role of gcRac1 in grass carp innate immunity. Copyright © 2015. Published by Elsevier Ltd.

    ABSTRACT: LBP/BPIs are pattern recognition receptors that are often present in vertebrates and in invertebrates, and they play a defense role against pathogens. We have identified 1698 bp cDNA sequence from the E. andrei earthworm with predicted amino acid sequence that shares homology with the LBP/BPI family (EaLBP/BPI). Sequence analysis of EaLBP/BPI proved the existence of two conserved domains with the potential ability to bind LPS. The predicted molecular mass of the EaLBP/BPI protein is 53.5 kDa, and its high basicity (pI 9.8) is caused by its high arginine content. Constitutive transcription of the Ealbp/bpi gene was shown in all tested tissues, with the highest level in coelomocytes and seminal vesicles; the lowest level was detected in the intestine. On the contrary, another earthworm LPS-binding molecule CCF (coelomic cytolytic factor) was expressed only in the intestine and coelomocytes. In E. andrei coelomocytes, the transcription of Ealbp/bpi gene was up-regulated in response to bacterial stimulation, reaching a maximum at 8 and 16 h post stimulation with B. subtilis and E. coli, respectively.

    ABSTRACT: The C-type lectin domain containing (CLEC) receptors including CD209 are expressed in vivo by monocytes, monocyte-derived macrophages and dendritic cells and by in vitro generated monocyte-derived cells. This paper reports the cloning and sequencing of a lectin molecule, CLEC4T1, in rainbow trout that is a homologue of the CLEC4 family. The expression pattern of the CLEC4T1 was investigated in vivo after infection with a bacterial pathogen and in cultured macrophages after modulation with microbial mimics. Trout CLEC4T1 was highly expressed in spleen and head kidney following infection with Yersinia ruckeri. Expression could also be induced in macrophage cultures by LPS but not by Poly I:C, and suggests that the regulation of CLEC4T1 expression in trout varies according to the nature of the stimulant A polyclonal CLEC4T1 antibody was generated and validated by Western blotting for use in evaluation of CLEC4T1(+) cells by flow cytometry analysis. Freshly isolated adherent trout head kidney cultures, potentially containing macrophages and dendritic cell precursors, showed an increase of CLEC4T1(+) cells (assessed by FACS) upon stimulation with recombinant interleukin-4/13A. The results suggest that CLEC4T1 is a useful marker for further characterisation of monocyte derived antigen presenting cells in fish. Copyright © 2015. Published by Elsevier Ltd.

    ABSTRACT: Biomphalaria glabrata acts as the intermediate host to the parasite, Schistosoma mansoni, and for this reason, the immune system of B. glabrata has been researched extensively. Several studies have demonstrated that the transcriptome profile of B. glabrata changes following exposure to a variety of pathogens, yet very little is known regarding the regulation of gene expression in this species. Nuclear factor kappaB (NF-κB) homologues have recently been identified in B. glabrata but few functional studies have been carried out on this family of transcription factors. The aims of this study therefore were to identify NF-κB binding sites (κB motifs) in B. glabrata and examine them via functional assays. Two different κB motifs were predicted. Furthermore, the Rel homology domain (RHD) of a B. glabrata NF-κB was able to bind these κB motifs in EMSAs, as well as a vertebrate κB motif. Copyright © 2015. Published by Elsevier Ltd.

    ABSTRACT: Interleukin 17 (IL17) is a proinflammatory cytokine that plays an important role in immune response. Recently, five novel IL17 homologs have been identified by screening and analyzing the genome of pacific oyster Crassostrea gigas. In the present study, the functions of CgIL17-5 were investigated by examining the distribution of its mRNA and protein, ligands binding and modulation in immune response. The mRNA expression levels of CgIL17-5 in hemocytes of oysters post twice challenges of Vibrio splendidus were all significantly up-regulated (P < 0.01), while the secondary pathogen infection attenuated the expression level of CgIL17-5 mRNA compared with the primary challenge. CgIL17-5 was found to be located on oyster hemocyte membranes through fluorescence confocal assay. The luciferase reporter assays showed that CgIL17-5 could activate the transfactors NF-κB, CREB and ATF-1, and involve in their signal pathways in HEK293T cells. Meanwhile, CgIL17-5 could augment the IL6 synthesis in HuVEC cells, playing the similar roles as human IL17 in inflammatory response. Additionally, the recombinant CgIL17-5 (rCgIL17-5) could directly bind peptidoglycan (PGN), lipopolysaccharide (LPS), poly (I:C) and β-1,3-glucan, with the highest affinity to PGN, and significantly inhibit the growth of Micrococcus luteus and Escherichia coli. All the results collectively suggested that CgIL17-5, as an ancient inflammatory cytokine, could not only activate signal transduction for the release of other cytokines, but also mediate the clearance of extracellular bacteria in oysters.

    ABSTRACT: There is increasing concern about the possible effect of pharmaceutical compounds may have on the fish immune system. Bath exposition of 17α-ethynylestradiol (EE2), a synthetic estrogen used in oral contraceptives, altered the immune response of the gilthead seabream (Sparus aurata L.), a marine hermaphrodite teleost. Tamoxifen (Tmx) is a selective estrogen-receptor modulator used in hormone replacement therapy, the effects of which are unknown in fish immunity. This study aims to investigate the effects of dietary administration of EE2 (5 μg/g food) and Tmx (100 μg/g food) on the immune response of gilthead seabream, and the capacity of the immune system to recover its functionality after a recovery period. The results show for the first time the reversibility of the effect of EE2 and Tmx on the fish immune response. Tmx promoted a transient alteration in hepatic vitellogenin gene expression of a different magnitude to that produced by EE2. Both, EE2 and Tmx inhibited the induction of interleukin-1β gene expression while reversed the inhibition of ROI production in leukocytes following vaccination. However, none of these effects were observed after ceasing EE2 and Tmx exposure. EE2 and Tmx stimulated the antibody response of vaccinated fish although Tmx, but not EE2, altered the antibody response and modulated the percentage of IgM(+) B lymphocytes of vaccinated fish during the recovery phase. Taken together, our results suggest that EE2 and Tmx might alter the capacity of fish to appropriately respond to infection and show that Tmx has a long-lasting effect on humoral adaptive immunity.

    ABSTRACT: The lack of a reliable mammalian neutrophil in vitro culture system has restricted our ability to examine their precise roles in mycobacterial infections. Previously, we developed the procedures for the isolation and culture of primary kidney-derived neutrophil-like cells from goldfish that are functionally and morphologically similar to mammalian neutrophils. The cultured primary goldfish neutrophils exhibited prolonged viability and functional effector responses. In this study, we demonstrate that when exposed to live or heat-killed Mycobacterium marinum, goldfish neutrophils increased their mRNA levels for several pro-inflammatory cytokines (il-1β1, il-1β2, tnfα-1, tnfα-2) and the cytokine receptors (ifngr1-1, tnfr1, tnfr2). These neutrophils also exhibited chemotaxis toward live mycobacteria, internalized the bacilli, and produced reactive oxygen intermediates (ROI) in response to pathogen exposure. The survival of intracellular mycobacteria was significantly reduced in activated neutrophils, indicating a robust killing response by these teleost granulocytes. We suggest that this goldfish primary neutrophil in vitro model system will provide important information regarding neutrophil-mediated host defense mechanisms against mycobacteria in teleosts as well as in higher vertebrates.

    ABSTRACT: Our understanding of how equine immunoglobulin genes are organized has increased significantly in recent years. For equine heavy chains, 52 IGHV, 40 IGHD, 8 IGHJ and 11 IGHC are present. Seven of these IGHCs are gamma chain genes. Sequence diversity is increasing between fetal, neonatal, foal and adult age. The kappa light chain contains 60 IGKV, 5 IGKJ and 1 IGKC, whereas there are 144 IGLV, 7 IGLJ, and 7 IGLC for the lambda light chain, which is expressed predominantly in horses. Significant transcriptional differences for IGLV and IGLC are identified in different breeds. Allotypic and allelic variants are observed for IGLC1, IGLC5, and IGLC6/7, and two IGLV pseudogenes are also transcribed. During age development, a decrease in IGLVs is noted, although nucleotide diversity and significant differences in gene usage increased. The following paper suggests a standardization of the existing nomenclature of immunoglobulin genes. Copyright © 2015. Published by Elsevier Ltd.

    ABSTRACT: The major histocompatibility complex (MHC) is a highly variable region of vertebrate genomes that encodes cellular proteins involved in the immune response. In addition to the benefits of MHC research in understanding the genetic basis of host resistance to disease, the MHC is an ideal candidate for studying genetic diversity under strong natural selection. However, the MHC of many non-model vertebrate taxa are poorly characterized, hindering an understanding of disease resistance and its application to conservation genetics in these groups. Squamates (lizards and snakes) remain particularly underrepresented despite their being the most diverse order of non-avian sauropsids. We characterized MHC class I sequence diversity from an Australian skink, the sleepy lizard (Tiliqua rugosa), using both cDNA and genomic sequence data and also present genomic class I sequences from the related skinks Tiliqua adelaidensis and Egernia stokesii. Phylogenetic analysis of Tiliqua and other published sqamate MHC class I sequences suggest that MHC diverged very early in Tiliqua as compared with the other studied squamates. We identified at least 4 classical MHC class I loci in T. rugosa and also shared polymorphism among T. rugosa, T. adelaidensis and E. stokesii in the sequences encoding peptide-binding α1 and α2 domains.

    ABSTRACT: Integrins are a family of cell adhesion molecules which play important roles in the regulation of cell adhesion, migration, proliferation, apoptosis and phagocytosis. In the present study, the immune function of an integrin from the oyster Crassostrea gigas (designated CgIntegrin) was characterized to understand the regulatory mechanism of hemocyte phagocytosis toward different microbes. The full-length cDNA of CgIntegrin was 2571 bp with an open reading frame (ORF) of 2397 bp, encoding a polypeptide of 799 amino acids. The mRNA transcripts of CgIntegrin were predominantly detected in hemocytes, gonad and adductor muscle, while lowly in hepatopancreas, mantle and gill. The mRNA expression level was up-regulated at 6 h post lipopolysaccharide (LPS) stimulation (p<0.01), while no significant change was observed after peptidoglycan (PGN) stimulation. The oyster hemocytes with relative high CgIntegrin expression level exhibited different phagocytic abilities towards different microorganism and particles, such as Gram-positive bacteria Vibrio splendidus, Gram-negative bacteria Staphylococcus aureus and latex beads. Moreover, the phagocytic rate towards V. splendidus was significantly decreased after the blockade of CgIntegrin using the polyclonal antibody. The recombinant CgIntegrin (rCgIntegrin) displayed agglutinating activity towards V. splendidus but not S. aureus and Y. lipolytica. It also exhibited a higher binding affinity towards LPS (compared to rTrx group) in a dose-dependent manner with the apparent dissociation constant (Kd) of 5.53 × 10(-6) M. The results indicated that CgIntegrin served as a pattern recognition receptor with LPS binding activity, which could directly bind to V. splendidus and enhance the phagocytosis of oyster hemocytes.

    ABSTRACT: Polymeric immunoglobulins (pIgs) mucosal secretion is mediated by the pIg secretory immune system (PISIS), which is composed of J-chain (JC) and antibody (IgM/IgA) producing cells (JC-AbPC), pIg receptor (pIgR) epithelial cell expression and the efficient release of secretory Igs (SIgs) to the mucosal lumen. A poor development or disturbances in this system may cause higher infection susceptibility, as observed in young and elderly people. In spite of this system's importance, few detailed studies regarding its development have been described in the lower respiratory tract of humans. Because the porcine model has been reported as an option for translational medicine to humans, we studied the tracheal and bronchial PISIS development in healthy, non-vaccinated, SPF, miniature Vietnamese pigs from birth to adulthood using immunohistochemistry and ELISAs. Our results demonstrated that pIgR was present at birth, and its expression increased with age. In contrast, JC-AbPC were low in neonatal pigs; however, colostrum was a source of IgM, SIgA, total IgA and IgG in respiratory secretions (trachea and bronchoalveolar lavages, nasal secretion and saliva) in piglets. JC-AbPC steadily increased in post-weaned, young and adult pigs, correlating with considerable increases in secretory and total Igs in the trachea and bronchi. These data suggest a compensatory role of maternal Igs at the respiratory mucosa in the absence of a structured PISIS before weaning. Furthermore, monomeric Igs (IgG and IgA) may also play an important role in respiratory protection and deserves a more thorough study. Copyright © 2015. Published by Elsevier Ltd.

    ABSTRACT: The interferon regulatory factors IRF1 and IRF2 of the IRF1 subfamily play essential roles in immune responses against viruses. IRF11 is a novel IRF gene of the IRF1 subfamily; IRF11 genes share almost the same evolutionary distance with IRF1 and IRF2 genes. However, the structure and characteristics of IRF11 gene in fish have been rarely reported. In our study, IRF1, IRF2 and IRF11 genes were identified and characterized from miiuy croaker genome. Results showed that the IRF1, IRF2 and IRF11 genes contain the same domains; each of these genes is composed of conserved gene organizations and characterized by gene synteny with the orthologous genes. Interestingly, IRF11 was likely found only in fish (but not specific to teleost fish). Evolutionary analysis results showed that IRF1 gene in mammals, IRF2 and IRF11 gene in fish underwent positive selection. IRF1, IRF2 and IRF11 were expressed in a wide range of miiuy croaker tissues. These genes also exhibited the same expression patterns after miiuy croaker was infected with poly(I:C). Therefore, our data enhanced our understanding of the functions and evolution of IRF11 in fish. Copyright © 2015. Published by Elsevier Ltd.
