[PMID: 38974974 PMCID: PMC11226982 DOI: 10.1016/j.isci.2024.110161] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Revised: 01/15/2024] [Accepted: 05/29/2024] [Indexed: 07/09/2024] Open
Abstract
Interferon (IFN) system is the primary mechanism of innate antiviral defense in immune response. To date, limited studies of IFN system were conducted in crustaceans. Previous report in Penaeus monodon demonstrated the interconnection of cytokine-like molecule Vago and inhibitor of kappa B kinase-nuclear factor κB (IKK-NF-κB) cascade against white spot syndrome virus (WSSV). This study further identified five different PmVago isoforms. Upon immune stimulation, PmVagos expressed against shrimp pathogens. PmVago1, PmVago4, and PmVago5 highly responded to WSSV, whereas, PmVago1 and PmVago4 RNAi exhibited a rapid mortality with elevated WSSV replication. Suppression of PmVago1 and PmVago4 negatively affected proPO system, genes in signal transduction, and AMPs. WSSV infection additionally induced PmVaog4 granule accumulation and cellular translocation to the area of cell membrane. More importantly, PmVago1 and PmVago4 promoters were stimulated by PmIKK overexpression; meanwhile, they further activated Dorsal and Relish promoter activities. These results suggested the possible roles of the cytokine-like PmVago via IKK-NF-κB cascade against WSSV infection.

Abstract
INTRODUCTION Antimicrobial peptides (AMPs) are valuable alternatives to traditional antibiotics, possess a variety of potent biological activities and exhibit immunomodulatory effects that alleviate difficult-to-treat infections. Clarifying the structure-activity relationships of AMPs can direct the synthesis of desirable peptide therapeutics. OBJECTIVES In this study, the lipopolysaccharide-binding domain (LBD) was identified through machine learning-guided directed evolution, which acts as a functional domain of the anti-lipopolysaccharide factor family of AMPs identified from Marsupenaeus japonicus. METHODS LBDA-D was identified as an output of this algorithm, in which the original LBDMj sequence was the input, and the three-dimensional solution structure of LBDB was determined using nuclear magnetic resonance. Furthermore, our study involved a comprehensive series of experiments, including morphological studies and in vitro and in vivo antibacterial tests. RESULTS The NMR solution structure showed that LBDB possesses a circular extended structure with a disulfide crosslink at the terminus and two 310-helices and exhibits a broad antimicrobial spectrum. In addition, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) showed that LBDB induced the formation of a cluster of bacteria wrapped in a flexible coating that ruptured and consequently killed the bacteria. Finally, coinjection of LBDB, Vibrio alginolyticus and Staphylococcus aureus in vivo improved the survival of M. japonicus, demonstrating the promising therapeutic role of LBDB for treating infectious disease. CONCLUSIONS The findings of this study pave the way for the rational drug design of activity-enhanced peptide antibiotics.

Genome-wide analysis of ATP-binding cassette (ABC) transporter in Penaeus vannamei and identification of two ABC genes involved in immune defense against Vibrio parahaemolyticus by affecting NF-κB signaling pathway. Int J Biol Macromol 2024; 262:129984. [PMID: 38342260 DOI: 10.1016/j.ijbiomac.2024.129984] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Revised: 01/23/2024] [Accepted: 01/30/2024] [Indexed: 02/13/2024]
Abstract
The ATP-binding cassette (ABC) transporters have crucial roles in various biological processes such as growth, development and immune defense in eukaryotes. However, the roles of ABC transporters in the immune system of crustaceans remain elusive. In this study, 38 ABC genes were systematically identified and characterized in Penaeus vannamei. Bioinformation analysis revealed that PvABC genes were categorized into ABC A-H eight subfamilies with 17 full-transporters, 11 half transporters and 10 soluble proteins, and multiple immunity-related cis-elements were found in gene promoter regions. Expression analysis showed that most PvABC genes were widely and highly expressed in immune-related tissues and responded to the stimulation of Vibrio parahaemolyticus. To investigate whether PvABC genes mediated innate immunity, PvABCC5, PvABCF1 and PvABCB4 were selected for dsRNA interference experiment. Knockdown of PvABCF1 and PvABCC5 not PvABCB4 increased the cumulative mortality of P. vannamei and bacterial loads in hepatopancreas after infection with V. parahaemolyticus. Further analysis showed that the PvABCF1 and PvABCC5 knockdown decreased expression levels of NF-κB pathway genes and antimicrobial peptides (AMPs). Collectively, these findings indicated that PvABCF1 and PvABCC5 might restrict V. parahaemolyticus challenge by positively regulating NF-κB pathway and then promoting the expression of AMPs, which would contribute to overall understand the function of ABC genes in innate immunity of invertebrates.

Abstract
Janus kinase/signal transducers and activators of transcription (JAK/STAT) signaling pathway plays an important role in antiviral immunity. This research reports the full-length DOME receptor gene in Penaeus monodon (PmDOME) and examines the effects of PmDOME and PmSTAT silencing on immune-related gene expressions in shrimp hemocytes during white spot syndrome virus (WSSV) infection. PmDOME and PmSTAT were up-regulated in shrimp hemocytes upon WSSV infection. Suppression of PmDOME and PmSTAT showed significant impacts on the expression levels of ProPO2 (melanization), Vago5 (interferon-like protein) and several antimicrobial peptides, including ALFPm3, Penaeidin3, CrustinPm1 and CrustinPm7. Silencing of PmDOME and PmSTAT reduced WSSV copy numbers and delayed the cumulative mortality caused by WSSV. We postulated that suppression of the JAK/STAT signaling pathway may activate the proPO, IFN-like antiviral cytokine and AMP production, resulting in a delay of WSSV-related mortality.

Host-pathogen coevolution drives innate immune response to Aphanomyces astaci infection in freshwater crayfish: transcriptomic evidence. BMC Genomics 2022; 23:600. [PMID: 35989333 PMCID: PMC9394032 DOI: 10.1186/s12864-022-08571-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Accepted: 04/20/2022] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND For over a century, scientists have studied host-pathogen interactions between the crayfish plague disease agent Aphanomyces astaci and freshwater crayfish. It has been hypothesised that North American crayfish hosts are disease-resistant due to the long-lasting coevolution with the pathogen. Similarly, the increasing number of latent infections reported in the historically sensitive European crayfish hosts seems to indicate that similar coevolutionary processes are occurring between European crayfish and A. astaci. Our current understanding of these host-pathogen interactions is largely focused on the innate immunity processes in the crayfish haemolymph and cuticle, but the molecular basis of the observed disease-resistance and susceptibility remain unclear. To understand how coevolution is shaping the host's molecular response to the pathogen, susceptible native European noble crayfish and invasive disease-resistant marbled crayfish were challenged with two A. astaci strains of different origin: a haplogroup A strain (introduced to Europe at least 50 years ago, low virulence) and a haplogroup B strain (signal crayfish in lake Tahoe, USA, high virulence). Here, we compare the gene expression profiles of the hepatopancreas, an integrated organ of crayfish immunity and metabolism. RESULTS We characterised several novel innate immune-related gene groups in both crayfish species. Across all challenge groups, we detected 412 differentially expressed genes (DEGs) in the noble crayfish, and 257 DEGs in the marbled crayfish. In the noble crayfish, a clear immune response was detected to the haplogroup B strain, but not to the haplogroup A strain. In contrast, in the marbled crayfish we detected an immune response to the haplogroup A strain, but not to the haplogroup B strain. CONCLUSIONS We highlight the hepatopancreas as an important hub for the synthesis of immune molecules in the response to A. astaci. A clear distinction between the innate immune response in the marbled crayfish and the noble crayfish is the capability of the marbled crayfish to mobilise a higher variety of innate immune response effectors. With this study we outline that the type and strength of the host immune response to the pathogen is strongly influenced by the coevolutionary history of the crayfish with specific A. astaci strains.

Abstract
Peptide therapeutics play a key role in the development of new medical treatments. The traditional focus on endogenous peptides has shifted from first discovering other natural sources of these molecules, to later synthesizing those with unique bioactivities. This review provides concise information concerning antimicrobial peptides derived from marine crustaceans for the development of new therapeutics. Marine arthropods do not have an adaptive immune system, and therefore, they depend on the innate immune system to eliminate pathogens. In this context, antimicrobial peptides (AMPs) with unique characteristics are a pivotal part of the defense systems of these organisms. This review covers topics such as the diversity and distribution of peptides in marine arthropods (crustacea and chelicerata), with a focus on penaeid shrimps. The following aspects are covered: the defense system; classes of AMPs; molecular characteristics of AMPs; AMP synthesis; the role of penaeidins, anti-lipopolysaccharide factors, crustins, and stylicins against microorganisms; and the use of AMPs as therapeutic drugs. This review seeks to provide a useful compilation of the most recent information regarding AMPs from marine crustaceans, and describes the future potential applications of these molecules.

Abstract
Anti-lipopolysaccharide factors (ALF) is an important antimicrobial peptide and critical effector molecule with a broad spectrum of antimicrobial activities in crustaceans. In addition to the previously reported five ALFs (MnALF1-5), another three ALFs [MnALF1, which is different from MnALF1 (ALF02818) that has been reported; MnALF6; and MnALF7] and an isoform of MnALF4 (MnALF4-isoform2) were newly identified from Macrobrachium nipponense in this study. MnALF6 has 134 amino acids and one single nucleotide polymorphism (SNP) in MnALF6 resulted in the change of 107th amino acid from E to D. Intron 1 retention produced longer transcript of MnALF6. The full length of MnALF7 has 691 bp with a 363 bp ORF encoding 120 amino acid protein. Three SNPs in MnALF2 resulted in the conversion of amino acids at positions 70, 73, and 91 from T70I73P91 to K70L73S91. The deletion of 13 bp in MnALF4 resulted in early termination of ORF, resulting in MnALF4-isoform2 with only 98 amino acids. The gDNAs of MnALF1, MnALF2, MnALF5, and MnALF6 contain three exons and two introns, while those of MnALF3 and MnALF7 contain three exons, one known intron, and one unknown intron. The MnALF1-7 in M. nipponense were widely distributed in multiple tissues. After white spot syndrome virus (WSSV) stimulation, the expression levels of MnALF1-7 changed. Knockdown of MnALF1-7 could evidently increase the expression of the envelope protein VP28 and the copy number of WSSV during viral infection. Further studies found that silencing of three transcription factors (Stat, Dorsal, and Relish) in M. nipponense significantly inhibit the synthesis of MnALF1-7 during the process of WSSV challenge. This study adds to the knowledge about the roles of ALFs in the innate immune responses to WSSV infection in M. nipponense.

Abstract
Yellow head virus (YHV) is a pathogen which causes high mortality in penaeid shrimp. Previous studies suggested that YHV enters shrimp cells via clathrin-mediated endocytosis. This research investigated the roles of clathrin adaptor protein 2 subunit β (AP-2β) from Penaeus monodon during YHV infection. PmAP2-β was continuously up-regulated more than twofold during 6-36 hpi. Suppression of PmAP2-β significantly reduced YHV copy numbers and delayed shrimp mortality. Quantitative RT-PCR revealed that knockdown of PmAP2-β significantly enhanced the expression level of PmSpätzle, a signaling ligand in the Toll pathway, by 30-fold at 6 and 12 hpi. Moreover, the expression levels of gene components in the Imd and JAK/STAT signaling pathways under the suppression of PmAP2-β during YHV infection were also investigated. Interestingly, anti-lipopolysaccharide factor isoform 3 (ALFPm3) was up-regulated by 40-fold in PmAP2-β knockdown shrimp upon YHV infection. In addition, silencing of PmAP2-β dramatically enhanced crustinPm1 expression in YHV-infected shrimp. Knockdown of ALFPm3 and crustinPm1 significantly reduced shrimp survival rate. Taken together, this work suggested that PmAP2-β-deficiency promoted the Toll pathway signalings, resulting in elevated levels of ALFPm3 and crustinPm1, the crucial antimicrobial peptides in defence against YHV.

Ge Q, Wang J, Li J, Li J. Identification, characterization, and functional analysis of Toll and ECSIT in Exopalaemon carinicauda. DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2021; 116:103926. [PMID: 33238179 DOI: 10.1016/j.dci.2020.103926] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Revised: 11/10/2020] [Accepted: 11/10/2020] [Indexed: 06/11/2023]
Abstract
Toll and evolutionary conserved signaling intermediate in Toll pathways (ECSIT) are two essential molecules in Toll/Toll-like receptor (TLR)-mediated signaling pathway. In this study, Toll and ECSIT (named as EcToll and EcECSIT) were identified for the first time from Exopalaemon carinicauda. EcToll mRNA transcripts were high expressed in hemocytes and gill, and EcECSIT was mainly expressed in gill. The expression levels of EcToll and EcECSIT in gills both responded rapidly to Vibrio parahaemolyticus and WSSV stimulations and three types of antimicrobial peptide (AMP) genes were significantly up-regulated by challenge with V. parahaemolyticus. Knockdown of EcToll or EcECSIT increased the sensitivity of E. carinicauda to V. parahaemolyticus challenge and double knockdown of both EcToll and EcECSIT significantly suppressed the bacterial clearance ability of E. carinicauda in vivo. Furthermore, suppressing EcToll restrained the upregulation of EcECSIT and AMPs and suppressing EcECSIT impaired expression of AMPs by V. parahaemolyticus injection, which indicated that EcToll restricted V. parahaemolyticus infection through activating EcECSIT to induce AMPs. This study provides valuable information about the function of Toll-ECSIT pathway in the innate immunity in crustacean.

The krüppel-like factor of Penaeus vannamei negatively regulates transcription of the small subunit hemocyanin gene as part of shrimp immune response. FISH & SHELLFISH IMMUNOLOGY 2020; 100:397-406. [PMID: 32201349 DOI: 10.1016/j.fsi.2020.03.035] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/21/2019] [Revised: 03/10/2020] [Accepted: 03/17/2020] [Indexed: 06/10/2023]
Abstract
Hemocyanin is a multifunctional respiratory glycoprotein, which has also been implicated in other biological functions in shrimp. Moreover, recent studies have revealed that hemocyanin is also involved in a broad range of immune-related activities in shrimp. However, in spite of the considerable interest in unraveling the reasons behind the multiple immune-related functions of hemocyanin, little is known about its transcriptional regulation. Here, DNA pull-down and Liquid Chromatography - Tandem Mass Spectrometry (LC-MS/MS) analyses were used to isolate and identify the putative transcription factor(s) that are involved in the transcriptional regulation of the small subunit hemocyanin gene of Penaeus vannamei (PvHMCs). Krüppel-like factor (designated PvKruppel), a zinc finger transcription factor homolog in P. vannamei, was identified among the putative transcription factors, while bioinformatics analysis revealed the presence of Krüppel-like factor binding site (KLF motif) on the core promoter region of PvHMCs. Mutational analysis and electrophoretic mobility shift assay (EMSA) confirmed that PvKruppel could bind to the KLF motif on the core promoter region of PvHMCs. Moreover, in response to lipopolysaccharide (LPS), Vibrio parahaemolyticus and white spot syndrome virus (WSSV) challenge, transcript levels of PvKruppel and PvHMCs were negatively correlated. Furthermore, overexpression of PvKruppel significantly reduced the promoter activity of PvHMCs, while PvKruppel knockdown by RNA interference or lipopolysaccharides (LPS) stimulation resulted in a significant increase in the transcript level of PvHMCs. Taken together, our present study provides mechanistic insights into the transcriptional regulation of PvHMCs by PvKruppel during shrimp immune response to pathogens.

Clone, identification and functional characterization of a novel toll (Shtoll1) from the freshwater crab Sinopotamon henanense in response to cadmium exposure and Aeromonas hydrophila infection. FISH & SHELLFISH IMMUNOLOGY 2020; 98:401-413. [PMID: 31953198 DOI: 10.1016/j.fsi.2020.01.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/10/2019] [Revised: 12/31/2019] [Accepted: 01/05/2020] [Indexed: 06/10/2023]
Abstract
Toll is essential in innate immune system which is important for defense against bacterial, fungal and viral infections in invertebrates. Our previous study showed that cadmium (Cd) could change the expression pattern of ShToll3 in the epithelium (gills and midgut from the freshwater crab Sinopotamon henanense) infected by Aeromonas hydrophila. To investigate the diverse innate immune roles of crustacean homolog Tolls, in this study, we cloned Shtoll1 from S. henanense. The full-length cDNA of Shtoll1 was 4746 bp, with an ORF of 3033 bp encoding a putative protein of 111 amino acids, a 5'-untranslated region of 255 bp and a 3'-untranslated region of 1713 bp. Phylogenetic analysis showed that ShToll1 was clustered into the group of DmToll1, DmToll 4 and DmToll 5. In addition, the tissue distribution results showed that Shtoll1 was expressed widely in different tissues, with the highest expression in heamocytes. Besides, Shtoll1 expressions were upregulated in heamocytes and hepatopancreas after A. hydrophila infection. At the same time, the increase of Shtoll1 expressions were examined in heamocytes in response to Cd exposure and A. hydrophila infection in combination. Through western blotting and immunohistochemical analysis, the ShToll1 expressions in heamocytes were increased in response to A. hydrophila and Cd independently as well as in combination. Moreover, the mRNA level of three antimicrobial peptides (AMPs) alf5, alf6, and c-lys, which possibly responded to Cd and A. hydrophila stimulation through Shtoll1, were analyzed. Thus, we conclude that Cd expand the susceptibility of ShToll1 to A. hydrophila infection in heamocytes. This suggest that ShToll1 may contribute to the innate immune defense of S. henanense against A. hydrophila and Cd in heamocytes.

Abstract
Anti-lipopolysaccharide factors (ALFs) are important host-defense molecules of crustaceans. They all contain a lipopolysaccharide-binding domain (LBD) and some ALFs exhibit strong antimicrobial activity. In this research, a Group G ALF from Penaeus monodon (ALFPm11) was studied. It is an anionic peptide specifically having a cationic and highly amphipathic LBD, with five positively charged residues separated by aromatic residues. It was abundantly expressed in the hepatopancreas of P. monodon normally but the expression level in other tissues was relatively low or undetectable. However, in the shrimps challenged by Vibrio, expression of ALFPm11 could be detected in all tissues. Chemically synthesized ALFPm11-LBD displayed high inhibitory activity (minimum inhibition concentration≤ 4 μM) against various bacteria, e.g. Exiguobacterium sp. L33, Bacillus sp. T2, and Acinetobacter sp. L32. It also displayed apparent activity in the agar well diffusion assay. Furthermore, it could efficiently induce agglutination of both Gram-positive and Gram-negative bacteria and cause significant membrane permeabilization of the bacteria. As a comparative study, ALFPm11-LBD showed a better or equal antimicrobial function to ALFPm3-LBD which was reported to possess strong antimicrobial activity against Gram-positive, Gram-negative bacteria and fungi. Thus, this research found a new effective ALF in P. monodon and demonstrated its antimicrobial mechanism, suggesting its potential applications in the future.

Abstract
The outbreak of diseases ordinarily results from the disruption of the balance and harmony between hosts and pathogens. Devoid of adaptive immunity, shrimp rely largely on the innate immune system to protect themselves from pathogenic infection. Two nuclear factor-κB (NF-κB) pathways, the Toll and immune deficiency (IMD) pathways, are generally regarded as the major regulators of the immune response in shrimp, which have been extensively studied over the years. Bacterial infection can be recognized by Toll and IMD pathways, which activate two NF-κB transcription factors, Dorsal and Relish, respectively, to eventually lead to boosting the expression of various antimicrobial peptides (AMPs). In response to white-spot-syndrome-virus (WSSV) infection, these two pathways appear to be subverted and hijacked to favor viral survival. In this review, the recent progress in elucidating microbial recognition, signal transduction, and effector regulation within both shrimp Toll and IMD pathways will be discussed. We will also highlight and discuss the similarities and differences between shrimps and their Drosophila or mammalian counterparts. Understanding the interplay between pathogens and shrimp NF-κB pathways may provide new opportunities for disease-prevention strategies in the future.

Abstract
The IKK-NF-κB signaling cascade is one of the crucial responsive mechanisms in inflammatory and immune responses. The key kinase proteins called inhibitor of kappa B kinases (IKKs) serve as the core elements involved in cascade activation. Here, the complete ORFs of IKK homologs, PmIKKβ, PmIKKε1, and PmIKKε2, from the black tiger shrimp Penaeus monodon were identified and characterized for their functions in shrimp antiviral responses. The PmIKK transcripts were widely expressed in various examined tissues and the PmIKKε protein was detected in all three types of shrimp hemocytes. Only the PmIKKε1 and PmIKKε2 were responsive to white spot syndrome virus (WSSV), yellow head virus (YHV) and a bacterium Vibrio harveyi infection, while the PmIKKβ exhibited no significant response to pathogen infection. On the contrary, suppression of PmIKKβ and PmIKKε by dsRNA-mediated RNA interference (RNAi) resulted in a rapid death of WSSV-infected shrimp and the significant reduction of an IFN-like PmVago4 transcript. Whereas, the mRNA levels of the antimicrobial peptides, ALFPm3 and CrustinPm5, and a transcription factor, PmDorsal were significantly increased, those of ALFPm6, CrustinPm1, CrustinPm7, PmVago1, PmRelish, and PmCactus were unaffected. Overexpression of PmIKKβ and PmIKKε in HEK293T cells differentially activated the NF-κB and IFNβ promoter activities, respectively. These results suggest that the PmIKKβ and PmIKKε may act as common factors regulating the expression of immune-related genes from various signaling pathways. Interestingly, the PmIKKs may also contribute a possible role in shrimp cytokine-like system and cross-talking between signaling transductions in innate immune responses.

Abstract
Hemocyanin (HMC) is a respiratory glycoprotein, which also plays multifunctional non-specific innate immune defense functions in shrimp. However, the transcriptional regulatory mechanisms of the hemocyanin gene expression have not been reported. In the present study, we cloned a 4324 bp fragment of small subunit hemocyanin (HMCs) gene of Litopenaeus vannamei including the 5'-flanking region, from upstream 2475 bp to downstream 1849 bp (exon 1-intron 1-exon 2) by genome walking method. Four deletion constructs were then generated and their promoter activity assessed using the luciferase reporter system. Interestingly, we identified an alternative promoter (+1516/+1849 bp) located in exon 2, which has stronger promoter activity than the full-length or the other constructs. Bioinformatics analyses revealed that the alternative promoter region contains two conserved binding sites of the transcription factor c-Jun. Mutational analysis and electrophoretic mobility shift assay showed that Litopenaeus vannamei c-Jun (Lvc-Jun) binds to the region +1582/+1589 bp and +1831/+1837 bp of the alternative promoter. Furthermore, overexpression of Lvc-Jun significantly increased the alternative promoter activity, while co-transfection with dsRNA-Lvc-Jun significantly reduced the alternative promoter activity of HMCs. Taken together, our present data indicate that the transcription factor Lvc-Jun is essential for the transcriptional regulation of the HMCs gene expression.

Abstract
Ammonia is a major aquatic environmental pollutant that negatively impacts shrimp health and commercial productivity. However, we currently do not fully understand the underlying molecular mechanisms of ammonia stress in shrimp. We therefore performed transcriptomic analysis of hepatopancreas from black tiger shrimp (Penaeus monodon) treated with ammonia-stress. We obtained 146,410,174 and 115,241,048 clean reads for the control and treatment groups, respectively. A total of 64,475 unigenes with an average length of 1275 bp and a N50 value of 2158 bp were assembled. A comparative transcriptome analysis identified 3462 differentially expressed genes, 177 of which are highly homologous with known proteins in aquatic species. Most of these genes showing the expression changes were related to immune function. Some significantly down-regulated genes are involved in purine metabolism and other metabolic pathways, which suggests that purineolytic capacity is an ammonia detoxification process in P. monodon, and metabolic depression is a strategy to reduce shrimp exposure to ammonia. Additionally, ammonia stress altered the expression patterns of key apoptosis genes (Bcl-xL, PERK, caspase 7, and caspase 10), confirmed that ammonia-stress induce oxidative stress and eventually even apoptosis. We also found evidence for the involvement of antioxidant defense in response to oxidative imbalance, given the regulation of peroxiredoxin 1, SOD, and CAT under ammonia stress. In conclusion, our study clarifies shrimp defensive response to ammonia toxicity and should benefit efforts to breed more ammonia-tolerant varieties.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2018; 84:371-381.

Abstract
Acute hepatopancreatic necrosis disease, AHPND, caused by a specific strain of Vibrio parahaemolyticus (VPAHPND), results in great loss of global shrimp production. Despite this, studies on shrimp defense mechanisms protecting against AHPND are few. In this study, suppression subtractive hybridization (SSH) was performed to identify differentially expressed genes from white shrimp Litopenaeus vannamei hepatopancreas upon VPAHPND infection at the early stages: 3 and 6 h post challenge and in the late stage at 48 h post challenge. Hemocyanin (HMC) is the most abundant gene identified as the up-regulated gene in the SSH library. Various hemocyanin subunits such as hemocyanin (HMC), hemocyanin subunit L1 (HMCL1), L2 (HMCL2), L3 (HMCL3), and L4 (HMCL4) were analyzed for their expression levels upon VPAHPND infection and in response to challenge with partially purified toxin of VPAHPND by qRT-PCR. Only HMC was highly up-regulated at 3 and 6 h post challenge in response to VPAHPND challenge. Two HMC subunits, HMCL3 and HMCL4, were up-regulated in the early phase of VPAHPND toxin injection. Furthermore, all subunits were down-regulated in the late phase of VPAHPND and toxin challenges. The native hemocyanin protein purified from shrimp hemolymph, identified as mixture of HMC and HMCL1, exhibited agglutination activity on VPAHPND. Injecting the purified native hemocyanin along with VPAHPND into shrimp decreased the number of bacteria in the hemolymph as compared to the VPAHPND challenged control. Moreover, pre-incubation of the purified native hemocyanin and VPAHPND toxin prior to injection into shrimp resulted in the decrease of cumulative mortality of shrimp when compared to the control. In addition, protein-protein interaction analysis carried out by ELISA technique indicated that hemocyanin exhibited VPAHPND toxin-neutralizing activity through direct interaction with PirA subunit with a dissociation constant of 6.83 × 10-6 M. Our results indicated that upon VPAHPND infection the expression of hemocyanin was induced and hemocyanin functions might involve agglutination of invading VPAHPND and also neutralization of VPAHPND secreted toxin via direct interacting with the PirA protein.

Abstract
Anti-lipopolysaccharide factor (ALF) is a type of antimicrobial peptides (AMPs) with a vital role in antimicrobial defense. Although a large amount of ALFs have been identified from neritic and fresh water crustacean species, no functional investigation of ALFs from deep-sea animals have been documented. In the present study, we characterized the immune function of an ALF molecule (named RspALF1) from the shrimp Rimicaris sp. residing in the deep-sea hydrothermal vent in Desmos, Manus Basin. RspALF1 shares 51.5%-62.4% overall sequence identities with known shrimp ALFs and contains the conserved LPS binding domain (LBD). Both recombinant RspALF1 (rRspALF1) and the LBD-derived peptide (ALF1P1) bound to the cell wall components of Gram-negative and Gram-positive bacteria and killed a wide range of bacteria, especially those from deep-sea hydrothermal field, by damaging bacterial cellular structures. The bactericidal activities of rRspALF1 and ALF1P1 were optimal and stably maintained from 4 °C to 37 °C, which is comparable to the ambient temperature range of the habitat of Rimicaris sp. In addition to bacteria, rRspALF1 and ALF1P1 also exhibited anti-fungal activity. rRspALF1 and ALF1P1 exhibited high killing efficiencies, which, in terms of MIC values, were ranged between 0.25 μM and 4 μM for bacteria and 4 μM-8 μM for fungi. When introduced in vivo, both rRspALF1 and ALF1P1 effectively inhibited bacterial infection in shrimp and reduced the dissemination of bacterial and viral pathogens in fish. Together, these results provide the first insight into the biological property of deep-sea ALF and indicate that RspALF1 very likely plays a significant role in immune defense by functioning as a highly effective antimicrobial with a broad target range.
