Functional and genomic characterization of a novel probiotic Lactobacillus johnsonii KD1 against shrimp WSSV infection. Sci Rep 2023; 13:21610. [PMID: 38062111 PMCID: PMC10703779 DOI: 10.1038/s41598-023-47897-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Accepted: 11/20/2023] [Indexed: 12/18/2023] Open
Abstract
White Spot syndrome virus (WSSV) causes rapid shrimp mortality and production loss worldwide. This study demonstrates potential use of Lactobacillus johnsonii KD1 as an anti-WSSV agent for post larva shrimp cultivation and explores some potential mechanisms behind the anti-WSSV properties. Treatment of Penaeus vannamei shrimps with L. johnsonii KD1 prior to oral challenge with WSSV-infected tissues showed a significantly reduced mortality. In addition, WSSV copy numbers were not detected and shrimp immune genes were upregulated. Genomic analysis of L. johnsonii KD1 based on Illumina and Nanopore platforms revealed a 1.87 Mb chromosome and one 15.4 Kb plasmid. Only one antimicrobial resistance gene (ermB) in the chromosome was identified. Phylogenetic analysis comparing L. johnsonii KD1 to other L. johnsonii isolates revealed that L. johnsonii KD1 is closely related to L. johnsonii GHZ10a isolated from wild pigs. Interestingly, L. johnsonii KD1 contains isolate-specific genes such as genes involved in a type I restriction-modification system and CAZymes belonging to the GT8 family. Furthermore, genes coding for probiotic survival and potential antimicrobial/anti-viral metabolites such as a homolog of the bacteriocin helveticin-J were found. Protein-protein docking modelling suggests the helveticin-J homolog may be able to block VP28-PmRab7 interactions and interrupt WSSV infection.

Abstract
Macrobrachium rosenbergii Taihu virus (MrTV) is a virulent pathogen that mainly threatens M. rosenbergii larvae. Rab proteins, which are essential for controlling intracellular membrane trafficking, are hijacked by multiple viruses to complete their life cycle. In this paper, we studied the function of M. rosenbergii Rab1A (MrRab1A) in the MrTV infection. Upon MrTV infection, the transcription level of MrRab1A was significantly up-regulated, indicating MrRab1A was a MrTV responsive gene and might be important for MrTV infection. Co-IP and co-localization assays revealed that MrRab1A could directly bind with MrTV and its capsid protein VP3. Moreover, the in vivo neutralization assay demonstrated that pre-incubation of MrTV with recombinant MrRab1A could partially block MrTV infection. These findings indicated that MrRab1A functioned as a virus-binding protein involved in MrTV infection, which shed new light on the mechanism of MrTV infection and provided a potential target for developing anti-MrTV therapies.

Abstract
Shrimp aquaculture has become a vital industry, meeting the growing global demand for seafood. Shrimp viral diseases have posed significant challenges to the aquaculture industry, causing major economic losses worldwide. Conventional treatment methods have proven to be ineffective in controlling these diseases. However, recent advances in RNA interference (RNAi) technology have opened new possibilities for combating shrimp viral diseases. This cutting-edge technology uses cellular machinery to silence specific viral genes, preventing viral replication and spread. Numerous studies have shown the effectiveness of RNAi-based therapies in various model organisms, paving the way for their use in shrimp health. By precisely targeting viral pathogens, RNAi has the potential to provide a sustainable and environmentally friendly solution to combat viral diseases in shrimp aquaculture. This review paper provides an overview of RNAi-based therapy and its potential as a game-changer for shrimp viral diseases. We discuss the principles of RNAi, its application in combating viral infections, and the current progress made in RNAi-based therapy for shrimp viral diseases. We also address the challenges and prospects of this innovative approach.

Simultaneous Production of a Virus-Like Particle Linked to dsRNA to Enhance dsRNA Delivery for Yellow Head Virus Inhibition. Viruses 2022; 14:v14122594.

Abstract
A co-expressed Penaeus stylirostris densovirus (PstDNV) capsid and dsRNA specific to the yellow head virus (YHV) protease (CoEx cpPstDNV/dspro) has been shown to suppress YHV replication in the Pacific white-legged shrimp (Litopenaeus vannamei). However, maintaining two plasmids in a single bacterial cell is not desirable; therefore, a single plasmid harboring both the PstDNV capsid and the dsRNA-YHV-pro gene was constructed under the regulation of a single T7 promoter, designated pET28a-Linked cpPstDNV-dspro. Following induction, this novel construct expressed an approximately 37-kDa recombinant protein associated with a roughly 400-bp dsRNA (Linked cpPstDNV-dspro). Under a transmission electron microscope, the virus-like particles (VLP; Linked PstDNV VLPs-dspro) obtained were seen to be monodispersed, similar to the native PstDNV virion. A nuclease digestion assay indicated dsRNA molecules were both encapsulated and present outside the Linked PstDNV VLPs-dspro. In addition, the amount of dsRNA produced from this strategy was higher than that obtained with a co-expression strategy. In a YHV infection challenge, the Linked PstDNV VLPs-dspro was more effective in delaying and reducing mortality than other constructs tested. Lastly, the linked construct provides protection for the dsRNA cargo from nucleolytic enzymes present in the shrimp hemolymph. This is the first report of a VLP carrying virus-inhibiting dsRNA that could be produced without disassembly and reassembly to control virus infection in shrimp.

Abstract
Rab7 is a member of the Rab GTPases protein family, and it plays an essential role in regulating trafficking organelles in higher animals. However, recent studies showed that it also participated in the immune response and cytophagy against pathogens in invertebrates. In the present study, the full-length of Rab7 from Procambarus clarkii (PcRab7) was cloned, and its function during pathogen infection and phagocytosis of haemocytes was also explored. The results showed that the full-length of PcRab7 was 3639 bp, containing a 618 bp open reading frame encoding 155 amino acids. The predicted molecular weight and isoelectric point of PcRab7 were 23.2 kDa and 5.77, respectively. PcRab7 was widely expressed in various tissues including haemocytes, intestine, muscle, gill, and hepatopancreas, and the highest expression level was in haemocytes. The mRNA transcripts of PcRab7 in the main organs (gill, intestine, and hepatopancreas, and haemocytes) were significantly affected by white spot syndrome virus (WSSV) and Aeromonas veronii infection. Subsequently, the prokaryotic and eukaryotic expression vectors were successfully constructed, and polyclonal antibodies, which could specifically recognize the endogenous Rab7 protein, were also obtained. Furthermore, the phagocytosis rate of haemocytes against FITC-labeled A. veronii was significantly decreased when the PcRab7 was silenced, while the over-expression of Rab7 increased the phagocytosis rate of haemocytes. The abnormal expression of Rab7 protein could also affect the survival rate of P. clarkii infected with WSSV or A. veronii. These results could provide a basis for further study on the immunological function of PcRab7.

Role of an FNIP Repeat Domain-Containing Protein Encoded by Megavirus Baoshan during Viral Infection. J Virol 2022; 96:e0081322. [PMID: 35762756 PMCID: PMC9327691 DOI: 10.1128/jvi.00813-22] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/30/2022] Open
Abstract
FNIP repeat domain-containing protein (FNIP protein) is a little-studied atypical leucine-rich repeat domain-containing protein found in social amoebae and mimiviruses. Here, a recently reported mimivirus of lineage C, Megavirus baoshan, was analyzed for FNIP protein genes. A total of 82 FNIP protein genes were identified, each containing up to 26 copies of the FNIP repeat, and mostly having an F-box domain at the N terminus. Both nucleotide and amino acid sequences of FNIP repeat were highly conserved. Most of the FNIP protein genes clustered together tandemly in groups of two to 14 genes. Nearly all FNIP protein genes shared similar expression patterns and were expressed 4 to 9 h postinfection. A typical viral FNIP protein, Mb0983, was selected for functional analysis. Protein interactome analysis identified two small GTPases, Rap1B and Rab7A, that interacted with Mb0983 in cytoplasm. The overexpression of Mb0983 in Acanthamoeba castellanii accelerated the degradation of Rap1B and Rab7A during viral infection. Mb0983 also interacted with host SKP1 and cullin-1, which were conserved components of the SKP1-cullin-1-F-box protein (SCF)-type ubiquitin E3 ligase complex. Deletion of the F-box domain of Mb0983 not only abolished its interaction with SKP1 and cullin-1 but also returned the speed of Rap1B and Rab7A degradation to normal in infected A. castellanii. These results suggested that Mb0983 is a part of the SCF-type ubiquitin E3 ligase complex and plays a role in the degradation of Rap1B and Rab7A. They also implied that other viral F-box-containing FNIP proteins might have similar effects on various host proteins. IMPORTANCE Megavirus baoshan encodes 82 FNIP proteins, more than any other reported mimiviruses. Their genetic and transcriptional features suggest that they are important for virus infection and adaption. Since most mimiviral FNIP proteins have the F-box domain, they were predicted to be involved in protein ubiquitylation. FNIP protein Mb0983 interacted with host SKP1 and cullin-1 through the F-box domain, supporting the idea that it is a part of the SCF-type ubiquitin E3 ligase complex. The substrates of Mb0983 for degradation were identified as the host small GTPases Rap1B and Rab7A. Combining the facts of the presence of a large number of FNIP genes in megavirus genomes, the extremely high expression level of the viral ubiquitin gene, and the reported observation that 35% of megavirus-infected amoeba cells died without productive infection, it is likely that megavirus actively explores the host ubiquitin-proteasome pathway in infection and that viral FNIP proteins play roles in the process.

Abstract
Innate immunity is the only defense system for resistance against infections in crustaceans. In crustaceans, white spot diseases caused by white spot syndrome virus (WSSV) are a serious viral disease with high accumulative mortality after infection. Attachment and entry into cells have been known to be two initial and important steps in viral infection. However, systematic information about the mechanisms related to WSSV infection in crustaceans is still limited. Previous studies have reported that cellular receptors are important in the innate immune system and are responsible for the recognition of foreign microorganisms and in the stimulation of the immune responses during infections. In this review, we summarize the current understanding of the functions of cellular receptors, including Toll, C-type lectin, scavenger receptor, β-integrin, polymeric immunoglobulin receptor, laminin receptor, globular C1q receptor, lipopolysaccharide-and β-1,3-glucan-binding protein, chitin-binding protein, Ras-associated binding, and Down syndrome cell adhesion molecule in the innate immune defense of crustaceans, especially shrimp and crabs, in response to WSSV infection. The results of this study provide information on the interaction between viruses and hosts during infections, which is important in the development of preventative strategies and antiviral targets in cultured aquatic animals.

Abstract
Recombinant Pichia pastoris biomass surface-expressing the viral binding protein PmRab7 (YSD-PmRab7) was prepared by fed-batch, aerobic fermentation with methanol induction for 48 h. By cell based ELISA assay, immunofluorescence and flow cytometry, 45% of the YSD-PmRab7 cells were positive for PmRab7. Freeze dried YSD-PmRab7 cells were added to formulated shrimp feed pellets at 0.25 g and 0.5 g per g feed and fed to 2 shrimp groups for 7 days prior to challenge with white spot syndrome virus (WSSV). Controls consisted of 1 shrimp group fed normal pellets and one fed pellets containing P. pastoris carrying an empty gene cassette. At 10 days post challenge, survival in the two control groups was 6.7 ± 6.6%, while it was 26.7 ± 6.6% in the 0.25 g YSD-PmRab7 group and significantly higher (p < 0.05) in the 0.5 g YSD-PmRab7 group at 46.7 ± 10.1%. Nested PCR assays and histopathological analysis revealed significantly lower WSSV replication levels in the 0.5 g YSD-PmRab7 group. The results indicated potential for development of YSD-PmRab7 cells as an oral prophylactic against WSSV in shrimp.

[PMID: 34584112 PMCID: PMC8478922 DOI: 10.1038/s41598-021-97828-w] [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: 08/06/2020] [Accepted: 08/24/2021] [Indexed: 02/08/2023] Open
Abstract
The 14-3-3 proteins interact with a wide variety of cellular proteins for many diverse functions in biological processes. In this study, a yeast two-hybrid assay revealed that two 14-3-3ε isoforms (14-3-3ES and 14-3-3EL) interacted with Rab11 in the white shrimp Litopenaeus vannamei (LvRab11). The interaction of 14-3-3ε and LvRab11 was confirmed by a GST pull-down assay. The LvRab11 open reading frame was 645 bp long, encoding a protein of 214 amino acids. Possible complexes of 14-3-3ε isoforms and LvRab11 were elucidated by in silico analysis, in which LvRab11 showed a better binding energy score with 14-3-3EL than with 14-3-3ES. In shrimp challenged with the white spot syndrome virus (WSSV), the mRNA expression levels of LvRab11 and 14-3-3ε were significantly upregulated at 48 h after challenge. To determine whether LvRab11 and binding between 14-3-3ε and LvRab11 are active against WSSV infection, an in vivo neutralization assay and RNA interference were performed. The results of in vivo neutralization showed that LvRab11 and complexes of 14-3-3ε/LvRab11 delayed mortality in shrimp challenged with WSSV. Interestingly, in the RNAi experiments, the silencing effect of LvRab11 in WSSV-infected shrimp resulted in decreased ie-1 mRNA expression and WSSV copy number. Whereas suppression of complex 14-3-3ε/LvRab11 increased WSSV replication. This study has suggested two functions of LvRab11 in shrimp innate immunity; (1) at the early stage of WSSV infection, LvRab11 might play an important role in WSSV infection processes and (2) at the late stage of infection, the 14-3-3ε/LvRab11 interaction acquires functions that are involved in immune response against WSSV invasion.

FISH & SHELLFISH IMMUNOLOGY 2021; 114:36-48. [PMID: 33864947 DOI: 10.1016/j.fsi.2021.04.007] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Revised: 03/30/2021] [Accepted: 04/06/2021] [Indexed: 06/12/2023]
Abstract
By using immunohistochemistry detection, yellow head virus (YHV) was found to replicate in granule-containing hemocytes including semi-granular hemocytes (SGC) and granular hemocytes (GC) during the early phase (24 h post injection) of YHV-infected shrimp. Higher signal of YHV infection was found in GC more than in SGC. Comparative phosphoproteomic profiles between YHV-infected and non-infected GC reveal a number of phosphoproteins with different expression levels. The phosphoprotein spot with later on identified as caspase-3 in YHV-infected GC is most interesting. Blocking caspase-3 function using a specific inhibitor (Ac-DEVD-CMK) demonstrated high replication of YHV and consequently, high shrimp mortality. The immunohistochemistry results confirmed the high viral load in shrimp that caspase-3 activity was blocked. Caspase-3 is regulated through a variety of posttranslational modifications, including phosphorylation. Analysis of phosphorylation sites of shrimp caspase-3 revealed phosphorylation sites at serine residue. Taken together, caspase-3 is a hemocytic protein isolated from shrimp granular hemocytes with a role in anti-YHV response and regulated through the phosphorylation process.

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.

Abstract
Argonaute family is phylogenetically subdivided into Ago and Piwi subfamilies that operate either transcriptional or post-transcriptional regulation in association with particular types of small RNAs. Among the four members of Ago subfamily (PmAgo1-4) found in black tiger shrimp Penaeus monodon, PmAgo4 exhibits gonad-restricted expression and takes part in transposon repression as the Piwi subfamily. While PmAgo1-3 participate in RNA interference (RNAi)-based mechanism, the role of PmAgo4 in RNAi is still mysterious, and was therefore investigated in this study. The results showed that knockdown of PmAgo4 in shrimp testis did not have a significant effect on the potency of PmRab7 silencing by dsPmRab7. In addition, replication of YHV as well as YHV-induced cumulative mortality in PmAgo4-knockdown shrimp are comparable to the control shrimp, suggesting the irrelevant association of PmAgo4 with RNAi-mediated gene silencing and antiviral immunity. Since PmAgo4 did not function in common with the Ago subfamily, its potential function in gametogenesis of male shrimp was further investigated. The reduction of PmAgo4 transcript levels in male shrimp revealed significant defect in testicular maturity as measured by Testicular Index (TI). Moreover, the numbers of mature sperm in spermatophore of PmAgo4-knockdown shrimp were significantly decreased comparing with the control shrimp. Our studies thus suggest a distinctive role of PmAgo4 that is not consistent with a dsRNA-mediate gene regulation and virus replication, but has a key function in controlling spermatogenesis in P. monodon.

Abstract
Carassius auratus gibelio is susceptible to the herpesviral hematopoietic necrosis (HVHN) disease caused by cyprinid herpesvirus 2 (CyHV-2) infection during the breeding process. Nevertheless, the report on biological response of CyHV-2 with C. auratus gibelio was limited, especially in vitro. In this study, host gene expression profiling was mostly analyzed in caudal fin cells of Carassius auratus gibelio (GiCF) underlying CyHV-2 infection. Transcriptomics and proteomics were employed to study the differential expression gene and revealed the host genes involved in pathway during the CyHV-2 infection. Transcriptome analysis revealed that compared with the control group, there were 11 335 and 19 421 differentially expressed unigenes at 48 h and at 96 h, respectively. Furthermore, proteome analysis showed that there were a total of 9008 proteins, among which 169 proteins were differential expression in the 48 h group and 502 proteins in the 96 h group. Notably, 10 and 158 differentially co-expressed genes at mRNA and protein levels (cDEGs) were reliably quantified at 48 h and 96 h, respectively. Interestingly, significantly different expressed genes both in the transcriptome and the proteome were identified, including GNG7, Hsp90a, THBS1 and RRM2. The result suggested that PI3k-AKT pathway was activated, but the p53 signaling pathway was suppressed. The above result will lay the foundation for understanding the mechanisms of host defense virus invasion during CyHV-2 infection.

Abstract
Yellow head disease (YHD) is an infectious disease of Penaeus monodon which is caused by the yellow head virus (YHV). YHV infection invariably leads to 100% shrimp mortality within 3-5 days. Currently, an effective method to prevent or cure shrimp from YHV infection has not been elucidated. Therefore, the molecular mechanism underlying YHV infection should be examined. In this study, early endosome antigen 1 (EEA1) protein that was involved in the tethering step of the vesicle and early endosome fusion was investigated during YHV infection. The open reading frame of P. monodon EEA1 (PmEEA1) was cloned and sequenced (3000 bp). It encoded a putative protein of 999 amino acids and contained the zinc finger C2H2 domain signature at the N-terminus and the FYVE domain at the C-terminus. Suppression of PmEEA1 by specific dsRNA in shrimp showed inhibition of YHV replication after 48 h post YHV injection (hpi). On the other hand, shrimp received only NaCl without any dsRNA showed high YHV levels at approximately one hundred thousand times at 24 hpi and 48 hpi. Moreover, silencing of PmEEA1 by specific dsRNA followed by YHV challenge demonstrated a delay in shrimp mortality from 60 hpi to 168 hpi when compared to the control. These results indicated that YHV required PmEEA1 for trafficking within the infected cells, strongly suggesting that PmEEA1 may be a potential target to control and prevent YHV infection in P. monodon.

Abstract
The Rab family is the most significant subfamily of small GTP-binding proteins. These proteins have widespread intracellular localization and play an important role in many biological processes. Rab7 plays a crucial role in the innate immune system of crustaceans. In the present study, we cloned and characterized Rab7 from Chinese mitten crab (Eriocheir sinensis), designated EsRab7. The full-length of the EsRab7 cDNA sequence is 1,257 bp and contains a 618-bp open reading frame encoding a 205-amino acid polypeptide. Bioinformatics analysis showed that the Rab7 protein was highly conserved during evolution. Quantitative real-time PCR showed the highest tissue expression in muscle, followed by hepatopancreas. EsRab7 was significantly upregulated in hemocytes after stimulation by Gram-positive Staphylococcus aureus or Gram-negative Vibrio parahaemolyticus. Further studies showed that EsRab7 knockdown during bacterial stimulation resulted in decreased bacterial phagocytosis. In addition, EsRab7 regulated the expression of antimicrobial peptides via the Toll signaling pathway. Collectively, these results demonstrate that EsRab7 plays critical roles in antimicrobial function in the Chinese mitten crab.

Abstract
Virus-like particles (VLPs) are potential containers for delivery of therapeutic agents at the nanoscale. In this study, the capsid protein of Infectious hypodermal and hematopoietic necrosis virus (IHHNV) was expressed in a baculovirus insect cell system. The 37-kDa recombinant protein containing the hexahistidine residues (His Tag) at N-terminal was purified using immobilized metal affinity chromatography (IMAC) and assembled into VLPs with a diameter of 23 ± 3 nm analyzed by transmission electron microscopy. We also verified that disassembly/reassembly of IHHNV-VLPs was controlled in the presence and absence of DTT. The efficiency of IHHNV-VLPs to encapsulate plasmid DNA was about 48.2%, and the VLPs encapsulating the pcDNA3.1(+)-EGFP plasmid DNA could recognize the primary shrimp hemocytes and deliver the loaded plasmid into cells by detection of expressed enhanced green fluorescent protein (EGFP). These results implied that the IHHNV-VLPs might be a good candidate for packaging and delivery of expressible plasmid DNA, and may produce an antiviral product in shrimp cells for gene therapy.

Abstract
VP19 is a major envelope protein of white spot syndrome virus (WSSV), an important pathogen of farmed shrimp. However, the exact function of VP19 in WSSV assembly and infection is unknown. To understand the function of VP19, the gene was knocked down by RNA interference. We found that the dsRNA specific for vp19 gene dramatically reduced the replication of WSSV genomic DNA in infected animals. Further investigation by transmission electron microscopy showed that inhibition of VP19 prevented envelope coating of progeny virions, resulting in a high amount of immature virus particles without outer layer (envelope) in the host cells. This finding was further confirmed by SDS-PAGE analysis, which showed the loss of VP19 and other envelope proteins from the improperly assembled virions. These results suggest that VP19 is essential for WSSV envelope coating.

Abstract
To investigate the role of the Rab7 effector RILP (Rab-interacting lysosomal protein) in white spot syndrome virus (WSSV) infection, the full-length cDNA of RILP (LvRILP) was cloned in Litopenaeus vannamei, which consists of 1595 bp and encodes a polypeptide of 411 amino acids. Sequence analysis and multiple sequence alignment displayed that LvRILP contained a conserved RILP region from 277 amino acid to 325 amino acid. Both the LvRILP and Rab7 mRNA were most highly expressed in stomach and most lowly expressed in hemocyte, which were significantly up-regulated and exhibited similar kinetics post WSSV infection. The interaction of Rab7 with LvRILP was verified by both GST Pull-down and ELISA. Meanwhile, the results of Pull-down assays showed that the GST-tagged VP28 (GST-VP28), His-tagged Rab7 (His-Rab7) and His-RILP formed a tripartite complex. After silencing by specific LvRILP dsRNA, the LvRILP mRNA level exhibited a significant reduction, and the expression levels of three WSSV genes ie1, wsv477 and vp28 all exhibited decreases at 24, 36 and 48 h post WSSV infection. These results suggested that the Rab7 effector RILP was involved in WSSV infection.

Abstract
Argonaute (Ago) proteins, the catalytic component of an RNA-induced silencing complex (RISC) in RNA interference pathway, function in diverse processes, especially in antiviral defense and transposon regulation. So far, cDNAs encoding four members of Argonaute were found in Penaeus monodon (PmAgo1-4). Two PmAgo proteins, PmAgo1 and PmAgo3 shared high percentage of amino acid identity to Ago1 and Ago2, respectively in other Penaeid shrimps. Therefore, the possible roles of PmAgo1 and PmAgo3 upon viral infection in shrimp were characterized in this study. The level of PmAgo1 mRNA expression in shrimp hemolymph was stimulated upon YHV challenge, but not with dsRNA administration. Interestingly, silencing of either PmAgo1 or PmAgo3 using sequence-specific dsRNAs impaired the efficiency of PmRab7-dsRNA to knockdown shrimp endogenous PmRab7 expression. Inhibition of yellow head virus (YHV) replication and delayed mortality rate were also observed in both PmAgo1-and PmAgo3-knockdown shrimp. In addition, silencing of PmAgo3 transcript, but not PmAgo1, revealed partial inhibition of white spot syndrome virus (WSSV) infection and delayed mortality rate. Therefore, our study provides insights into PmAgo1and PmAgo3 functions that are involved in a dsRNA-mediated gene silencing pathway and play roles in YHV and WSSV replication in the shrimp.

Abstract
Yellow head virus (YHV) is one of the most serious pathogens that causes worldwide shrimp production loss. It enters the cells via clathrin-mediated endocytosis and utilizes small GTPase Rab proteins such as PmRab5 and PmRab7 for intracellular trafficking. In this study, molecular cloning and functional analysis of Rab11 during YHV infection were investigated. PmRab11 cDNA was cloned by Rapid amplification of cDNA ends (RACEs). It contained two forms of sizes 1200 and 1050 bp distinct at the 5' UTR. The coding region of PmRab11 was 645 bp, encoding 214 amino acids. It also demonstrated the characteristics of Rab11 proteins containing five GTP-binding domains, five Rab family domains, four Rab subfamily domains and a prenylation site at the C-terminus. Suppression of PmRab11 using dsRNA-PmRab11 either before or after YHV-challenge resulted in significant inhibition of YHV levels in the hemocytes and viral release in the supernatant in both mRNA and protein levels. In addition, the silencing effect of PmRab11 in YHV-infected shrimps resulted in a delay in shrimp mortality for at least 2 days. Immunofluorescence study showed co-localization between PmRab11 and YHV at 24-72 h post YHV-challenge. In contrast, the co-localization signals were absence in the PmRab11 knockdown hemocytes and the YHV signals accumulated at the perinuclear region at 24 h post YHV-challenge. Then, accumulation of YHV was hardly observed after 48-72 h. These results suggested that PmRab11 is required for YHV infection in shrimp.

Abstract
The anti-lipopolysaccharide factor isoform 3 (ALFPm3), the antimicrobial peptide from Penaeus monodon, possesses antibacterial and antiviral activities. Although the mechanism of action of ALFPm3 against bacteria has been revealed but its antiviral mechanism is still unclear. To further study how the ALFPm3 exhibits antiviral activity against the enveloped virus, white spot syndrome virus (WSSV), the ALFPm3-interacting proteins from WSSV were sought and identified five ALFPm3-interacting proteins, WSSV186, WSSV189, WSSV395, WSSV458, and WSSV471. Only the interaction between ALFPm3 and WSSV189, however, has been confirmed to be involved in anti-WSSV activity of ALFPm3. Herein, the interactions between ALFPm3 and rWSSV186, rWSSV395, rWSSV458, or rWSSV471 were further analyzed and confirmed by in vitro pull-down assay. Western blot analysis and immunoelectron microscopy showed that the uncharacterized proteins, WSSV186 and WSSV471, were nucleocapsid and envelope proteins, respectively. The decrease of shrimp survival after injection the shrimp with mixtures of each rWSSV protein, rALFPm3 and WSSV as compared to those injected with rALFPm3-neutralizing WSSV was clearly observed indicating that all rWSSV proteins could interfere with the neutralization effect of rALFPm3 on WSSV similar to that reported previously for WSSV189. Morphological change on WSSV after incubation with rALFPm3 was observed by TEM. The lysed WSSV virions were clearly observed where both viral envelope and nucleocapsid were dismantled. The results lead to the conclusion that the ALFPm3 displays direct effect on the viral structural proteins resulting in destabilization and breaking up of WSSV virions.

Abstract
Viral pathogens pose a primary threat to global shrimp aquaculture. Despite the urgent industry need for them, practical anti-viral control methods are unavailable due, in part, to lack of an adaptive immune response in crustaceans that renders conventional vaccination methods ineffective. One currently studied method of high interest for protecting shrimp against viral infection relies on the post-transcriptional gene silencing mechanism called RNA interference (RNAi) that is induced by gene-specific constructs of double stranded RNA (dsRNA). Although this approach was first described for successful protection of shrimp against white spot disease (WSD) by injecting dsRNA specific to genes of white spot syndrome virus (WSSV) into shrimp in the laboratory in 2005 no practical method for use of dsRNA in shrimp farms has been developed to date. The apparent bottleneck for farm-scale applications of RNAi-mediated viral control in shrimp aquaculture is the lack of simple and cost-effective delivery methods. This review summarizes recent studies on use and delivery of dsRNA to shrimp via injection and oral routes in hatcheries and on farms and it discusses the research directions that might lead to development of practical methods for applications with farmed shrimp. Oral delivery methods tested so far include use of dsRNA-expressing bacteria as a component of dry feed pellets or use of living brine shrimp (Artemia) pre-fed with dsRNA before they are fed to shrimp. Also tested have been dsRNA enclosed in nanocontainers including chitosan, liposomes and viral-like particles (VLP) before direct injection or use as components of feed pellets for hatchery or pond-reared shrimp.

Abstract
Background Horizontal transfer (HT) of genetic materials is increasingly being found in both animals and plants and mainly concerns transposable elements (TEs). Many crustaceans have big genome sizes and are thus likely to harbor high TE contents. Their habitat might offer them ample opportunities to exchange genetic materials with organisms that are ecologically close but taxonomically distant to them. Results In this study, we analyzed the transcriptome of Pacific white shrimp (Litopenaeus vannamei), an important economic crustacean, to explore traces of HT events. From a collection of newly assembled transcripts, we identified 395 high reliable TE transcripts, most of which were retrotransposon transcripts. One hundred fifty-seven of those transcripts showed highest similarity to sequences from non-arthropod organisms, including ray-finned fishes, mollusks and putative parasites. In total, 16 already known L. vannamei TE families are likely to be involved in horizontal transfer events. Phylogenetic analyses of 10 L. vannamei TE families and their homologues (protein sequences) revealed that L. vannamei TE families were generally more close to sequences from aquatic species. Furthermore, TEs from other aquatic species also tend to group together, although they are often distantly related in taxonomy. Sequences from parasites and microorganisms were also widely present, indicating their possible important roles in HT events. Expression profile analyses of transcripts in two NCBI BioProjects revealed that transcripts involved in HT events are likely to play important roles in antiviral immunity. More specifically, those transcripts might act as inhibitors of antiviral immunity. Conclusions Close ecological relationship, especially predation, might greatly facilitate HT events among aquatic species. This could be achieved through exchange of parasites and microorganisms, or through direct DNA flow. The occurrence of HT events may be largely incidental, but the effects could be beneficial for recipients.

Abstract
Members of the Ras-like GTPase superfamily are key regulators of diverse cellular and developmental events, including differentiation, cell division, vesicle transport, nuclear assembly, and cytoskeleton control. In this study, three Ras family members (MjRap, MjRas, and MjRal) were cloned from Marsupenaeus japonicus. The full lengths of MjRap, MjRas, and MjRal are 788, 1330, and 2074 bp, which encode the proteins of 186, 202, and 198 amino acids respectively. Phylogenetic analysis showed that Rap, Ras, and Ral from different species gather together. The MjRap, MjRas, and MjRal genes were ubiquitously expressed in the hemocytes, hepatopancreas, gills, stomach, and muscle. Results from the quantitative real-time polymerase chain reaction (qRT-PCR) showed that MjRal in the gills was upregulated 48 and 72 h post-White spot syndrome virus (WSSV) challenge. No change in the MjRap or MjRas transcript was observed in the gills under the WSSV challenge. The RNAi of MjRal could enhance the WSSV replication. Injection of rMjRal protein could inhibit WSSV replication, but had no effect on VP28 expression. So, it could be concluded that MjRal was involved in shrimp anti-viral innate immune defense by inhibiting the WSSV replication.

Abstract
Viral responsive protein 15 (PmVRP15) has been identified as a highly up-regulated gene in the hemocyte of white spot syndrome virus (WSSV)-infected shrimp Penaeus monodon. However, the function of PmVRP15 in host-viral interaction was still unclear. To elucidate PmVRP15 function, the interacting partner of PmVRP15 from WSSV was screened by yeast two-hybrid assay and then confirmed by co-immunoprecipitation (Co-IP). Only WSV399 protein was identified as a PmVRP15 binding protein; however, the function of WSV399 has not been characterized. Localization of WSV399 on the WSSV virion was revealed by immunoblotting analysis (in vitro) and immunoelectron microscopy (in vivo). The results showed that WSV399 is a structural protein of the WSSV virion and is particularly located on the tegument. Gene silencing of wsv399 in WSSV-infected shrimp reduced the percentage of cumulative mortality by 74%, although the expression level of a viral replication marker gene, vp28, was not changed suggesting that WSV399 might not involved in viral replication but viral assembly. Because it has already been known that tegument proteins function in capsid transport during viral trafficking and assembly, interaction between PmVRP15 on hemocyte nuclear membrane and the WSV399 viral tegument protein suggests that PmVRP15 might be required for trafficking and assembly of WSSV during infection.

Abstract
Protection of shrimp from yellow head virus (YHV) infection has been demonstrated by injection and oral delivery of dsRNA-YHV protease gene (dsYHV) or shrimp endogenous gene (dsRab7). However, to achieve complete viral suppression and to prolong dsRNA activity, the development of an effective dsRNA delivery system is required. In this study, four cationic liposomes were synthesized and tested for their ability to increase dsRNA efficiency. The results demonstrated that entrapping dsYHV in a cholesterol-based cationic liposome gave the best protection against YHV infection when compared with other cationic lipids. The cholesterol-based cationic liposome-dsYHV (Chol-dsYHV) complex conferred YHV protection in a dose-dependent manner. Injection with Chol-dsYHV at 0.05μg dsYHV/g shrimp could give comparable level of YHV protection to the injection with 1.25μg naked dsYHV/g shrimp. The shrimp injected with Chol- dsYHV at 1.25μg dsRNA/g shrimp showed only 50% mortality at 60days post injection whereas the naked dsYHV at the same concentration gave 90% mortality. Thus, the liposome-entrapped dsYHV could lower an effective dsRNA concentration in viral protection and prolong dsRNA activity. In addition, encapsulating dsRab7 in the cholesterol-based cationic liposome could protect the dsRab7 from enzymatic digestion, and continuous feeding the shrimp with the diet formulated with the liposome-entrapped dsRab7 for 4days in the total of 960μg dsRab7/g shrimp could enhance YHV protection efficiency compared with the naked dsRab7. Our studies reveal that cholesterol-based cationic liposome is a promising dsRNA carrier to enhance dsRNA efficiency in both injection and oral delivery systems.

Abstract
In the present study, a suitable carrier system was developed for the delivery of dsRNA into Penaeus monodon (P. monodon) post larvae to silence the Monodon baculovirus (MBV) structural gene of p74. The carrier system was developed by layer by layer adsorption of oppositely charged chitosan-dextran sulfate, on charged silica nanoparticles. The silica template was removedto produce multilayered hollow nanocapsules (CS-DS) that were utilized for dsRNA loading at an alkaline pH. The capsule's surface was modified by conjugating with shrimp feed for enhanced cellular uptake. In vivo cellular uptake of CS-DS/FITC loaded nanocapsules conjugated with feed was studied after oral administration into post-larvae. The results revealed that the encapsulated FITC was effectively delivered and exhibited a sustained release into the cytoplasm of shrimp post-larvae. The MBV challenge study for structural gene p74was conducted after 3-25 days of post infection (dpi) with respective CS-DS/dsRNA coated with feed. The results showed a significant survival rate of 86.63% and effective gene silencing in P. monodon. Our findings indicated that the delivery of dsRNA using shrimp feed coatedCS-DSnanocapsules could be a novel approach to prevent viral infections in shrimp.

Abstract
In previous work, small ubiquitin-like modifier (SUMO) in hemocytes of Chinese shrimp Fenneropenaeus chinensis was found to be up-regulated post-white spot syndrome virus (WSSV) infection using proteomic approach. However, the role of SUMO in viral infection is still unclear. In the present work, full length cDNAs of SUMO (FcSUMO) and SUMO-conjugating enzyme E2 UBC9 (FcUBC9) were cloned from F. chinensis using rapid amplification of cDNA ends approach. The open reading frame (ORF) of FcSUMO encoded a 93 amino acids peptide with the predicted molecular weight (M.W) of 10.55 kDa, and the UBC9 ORF encoded a 160 amino acids peptide with the predicted M.W of 18.35 kDa. By quantitative real-time RT-PCR, higher mRNA transcription levels of FcSUMO and FcUBC9 were detected in hemocytes and ovary of F. chinensis, and the two genes were significantly up-regulated post WSSV infection. Subsequently, the recombinant proteins of FcSUMO and FcUBC9 were expressed in Escherichia coli BL21 (DE3), and employed as immunogens for the production of polyclonal antibody (PAb). Indirect immunofluorescence assay revealed that the FcSUMO and UBC9 proteins were mainly located in the hemocytes nuclei. By western blotting, a 13.5 kDa protein and a 18.7 kDa protein in hemocytes were recognized by the PAb against SUMO or UBC9 respectively. Furthermore, gene silencing of FcSUMO and FcUBC9 were performed using RNA interference, and the results showed that the number of WSSV copies and the viral gene expressions were inhibited by knockdown of either SUMO or UBC9, and the mortalities of shrimp were also reduced. These results indicated that FcSUMO and FcUBC9 played important roles in WSSV infection.

Abstract
The world production of shrimp such as the Malaysian giant freshwater prawn, Macrobrachium rosenbergii is seriously affected by the white spot syndrome virus (WSSV). There is an urgent need to understand the host pathogen interaction between M. rosenbergii and WSSV which will be able to provide a solution in controlling the spread of this infectious disease and lastly save the aquaculture industry. Now, using Next Generation Sequencing (NGS), we will be able to capture the response of the M. rosenbergii to the pathogen and have a better understanding of the host defence mechanism. Two cDNA libraries, one of WSSV-challenged M. rosenbergii and a normal control one, were sequenced using the Illumina HiSeq™ 2000 platform. After de novo assembly and clustering of the unigenes from both libraries, 63,584 standard unigenes were generated with a mean size of 698bp and an N50 of 1137bp. We successfully annotated 35.31% of all unigenes by using BLASTX program (E-value <10-5) against NCBI non-redundant (Nr), Swiss-Prot, Kyoto Encyclopedia of Genes and Genome pathway (KEGG) and Orthologous Groups of proteins (COG) databases. Gene Ontology (GO) assessment was conducted using BLAST2GO software. Differentially expressed genes (DEGs) by using the FPKM method showed 8443 host genes were significantly up-regulated whereas 5973 genes were significantly down-regulated. The differentially expressed immune related genes were grouped into 15 animal immune functions. The present study showed that WSSV infection has a significant impact on the transcriptome profile of M. rosenbergii's hepatopancreas, and further enhanced the knowledge of this host-virus interaction. Furthermore, the high number of transcripts generated in this study will provide a platform for future genomic research on freshwater prawns.

Abstract
Since its emergence in the 1990s, White Spot Disease (WSD) has had major economic and societal impact in the crustacean aquaculture sector. Over the years shrimp farming alone has experienced billion dollar losses through WSD. The disease is caused by the White Spot Syndrome Virus (WSSV), a large dsDNA virus and the only member of the Nimaviridae family. Susceptibility to WSSV in a wide range of crustacean hosts makes it a major risk factor in the translocation of live animals and in commodity products. Currently there are no effective treatments for this disease. Understanding the molecular basis of disease processes has contributed significantly to the treatment of many human and animal pathogens, and with a similar aim considerable efforts have been directed towards understanding host-pathogen molecular interactions for WSD. Work on the molecular mechanisms of pathogenesis in aquatic crustaceans has been restricted by a lack of sequenced and annotated genomes for host species. Nevertheless, some of the key host-pathogen interactions have been established: between viral envelope proteins and host cell receptors at initiation of infection, involvement of various immune system pathways in response to WSSV, and the roles of various host and virus miRNAs in mitigation or progression of disease. Despite these advances, many fundamental knowledge gaps remain; for example, the roles of the majority of WSSV proteins are still unknown. In this review we assess current knowledge of how WSSV infects and replicates in its host, and critique strategies for WSD treatment.

Yellow head virus infection in black tiger shrimp reveals specific interaction with granule-containing hemocytes and crustinPm1 as a responsive protein. DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2016; 54:126-136. [PMID: 26384157 DOI: 10.1016/j.dci.2015.09.005] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/01/2015] [Revised: 09/09/2015] [Accepted: 09/10/2015] [Indexed: 06/05/2023]
Abstract
Yellow head virus (YHV) causes acute infections and mass mortality in black tiger shrimp culture. Our study aims to investigate molecular interaction between YHV and circulating hemocytes of Penaeus monodon at early infection. Total shrimp hemocytes were isolated by Percoll gradient centrifugation and identified by flow cytometric analysis. At least three types of hemocyte cells were identified as hyaline, semi-granular, and granular hemocytes. Experimental infection of YHV in shrimp culture demonstrated drastic changes in total and each hemocyte cell counts. Immunohistochemistry analysis demonstrated interaction and replication of YHV mainly with the granule-containing hemocytes and little to none in hyaline cell. These granule-containing hemocytes are proposed to be YHV targets providing the first line of defense to viral infection. Protein expression profiling of granule-containing hemocytes revealed several immune-responsive proteins including antimicrobial protein crustins (crustinPm1 and crustinPm4), alpha-2-macroglobulin, and kazal-type serine proteinase inhibitor. During an early phase of YHV infection at 6 hpi crustinPm1 illustrated a significant increase of mRNA and protein expression level in plasma. The results suggest that an antimicrobial crustinPm1 may participate in shrimp defense mechanism against YHV, especially on the granule-containing hemocytes.

Abstract
Viruses with diverse virion architectures demarcated into four families in the order Nidovirales have been discovered in vertebrate mammalian and fish species, as well as in invertebrate crustacean and mosquito species. The order is unified by nidoviruses sharing intermediate (12.7 kb) to very long (31.7 kb) (+) ssRNA genomes, each possessing a long 5′-terminal gene encoding overlapping ORF1a and ORF1b reading frames that contain a diversity of functionally related enzymes and that are translated in toto using a −1 ribosomal frameshift mechanism, as well as by semiconserved strategies for transcribing a nested set of 3′-coterminal subgenomic mRNAs that translate the viral proteins. The nidovirus that is most important to an aquaculture species is yellow head virus (YHV), which causes disease in shrimp farmed throughout the Eastern Hemisphere and is classified in the genus Okavirus, family Roniviridae. Fathead minnow nidovirus, genus Bafinivirus, subfamily Torovirinae, family Coronaviridae, also causes disease in minnows grown for the baitfish industry in the United States. Virions similar in morphology to okaviruses and bafiniviruses have also been detected in several crab species. Of these, however, only Eriocheir sinensis ronivirus, which causes disease in the Chinese mitten crab, an important freshwater aquaculture species in China, has been shown to possess a ~22 kb ssRNA genome that supports its being a nidovirus, but its taxonomic classification awaits genome sequence analysis. This chapter provides an overview of the structure, replication and biology of these viruses with a particular focus on YHV disease characteristics, diagnostic methods and disease prevention strategies.

Abstract
UNLABELLED Spiroplasma eriocheiris, as a novel aquaculture pathogen, has led into catastrophic economic losses in aquaculture. The Macrobrachium rosenbergii hemocytes were major target cells in S. eriocheiris infection. Our study was designed to examine the hemocytes' immune response at the protein levels. The differential proteomes of the prawn hemocytes were analyzed immediately prior to injection with the pathogen, and at 192h post-injection by isobaric tags for relative and absolute quantization (iTRAQ) labeling, followed by liquid chromatogramphytandem mass spectrometry (LC-MS/MS). A total of 69 differentially expressed proteins were identified. Forty-nine proteins were up-regulated and 20 proteins were down-regulated resulting from a S. eriocheiris infection. Up-regulated proteins included vertebrate gliacolin-like protein, vitellogenin, Gram-negative binding protein 1, alpha2 macroglobulin isoform 2 (a2M), etc. Down-regulated proteins, involved with beta-1,3-glucan-binding protein (BGBP), immunoglobulin like, Rab7, lipopolysaccharide and β-1,3-glucan (LGBP), actin-related protein, etc. Selected bioactive factors (tachylectin, α2M and vitellogenin, BGBP, C-type lectin, LGBP and Rab7) were verified by their immune roles in the S. eriocheiris infection using real-time PCR. The present work could serve as a basis for future studies on the proteins implicated in the susceptibility/resistance of M. rosenbergii to S. eriocheiris, as well as contribute to our understanding of disease processes in prawns. BIOLOGICAL SIGNIFICANCE This is the first time using an iTRAQ approach to analyze proteomes of M. rosenbergii mobilized against S. eriocheiris infection and substantiated the hemocytes' proteomic changes in M. rosenbergii using an infection model. The results reported here can provide a significant step forward toward a more complete elucidation of the immune relationship between M. rosenbergii and the pathogen S. eriocheiris.

Abstract
With the destruction of the ecological environment, shrimp cultivation in China has been seriously affected by outbreaks of infectious diseases. Rab, which belong to small GTPase Ras superfamily, can regulate multiple steps in eukaryotic vesicle trafficking including vesicle budding, vesicle tethering, and membrane fusion. Knowledge of Rab in shrimp is essential to understanding regulation and detoxification mechanisms of environmental stress. In this study, we analyzed the functions of Rab from the Pacific white shrimp, Litopenaeus vannamei. Full-length cDNA of Rab was obtained, which was 751 bp long, with open reading frame encoding 206 amino acids. In this study, for the first time, the gene expression of Rab of L. vannamei was analyzed by quantitative real-time PCR after exposure to five kinds of environmental stresses (bacteria, pH, Cd, salinity and low temperature). The results demonstrate that Rab is sensitive and involved in bacteria, pH, and Cd stress responses and Rab is more sensitive to bacteria than other stresses. Therefore we infer that Rab may have relationship with the anti-stress mechanism induced by environment stress in shrimp and Rab could be used as critical biomarkers for environmental quality assessment.

Abstract
Small RNAs, 21-24 nucleotides in length, are non-coding RNAs found in most multicellular organisms, as well as in some viruses. There are three main types of small RNAs including microRNA (miRNA), small-interfering RNA (siRNA), and piwi-interacting RNA (piRNA). Small RNAs play key roles in the genetic regulation of eukaryotes; at least 50% of all eukaryote genes are the targets of small RNAs. In recent years, studies have shown that some unique small RNAs are involved in the immune response of crustaceans, leading to lower or higher immune responses to infections and diseases. SiRNAs could be used as therapy for virus infection. In this review, we provide an overview of the diverse roles of small RNAs in the immune defense mechanisms of crustaceans.

Abstract
Viral disease outbreaks are a major concern impeding the development of the shrimp aquaculture industry. The viral disease due to white spot syndrome virus (WSSV) observed in early 1990s still continues unabated affecting the shrimp farms and cause huge economic loss to the shrimp aquaculture industry. In the absence of effective therapeutics to control WSSV, it is important to understand viral pathogenesis and shrimp response to WSSV at the molecular level. Identification and molecular characterization of WSSV proteins and receptors may facilitate in designing and development of novel therapeutics and antiviral drugs that may inhibit viral replication. Investigations into host-pathogen interactions might give new insights to viral infectivity, tissue tropism and defence mechanism elicited in response to WSSV infection. However, due to the limited information on WSSV gene function and host immune response, the signalling pathways which are associated in shrimp pathogen interaction have also not been elucidated completely. In the present review, the focus is on those shrimp proteins and receptors that are potentially involved in virus infection or in the defence mechanism against WSSV. In addition, the major signalling pathways involved in the innate immune response and the role of apoptosis in host-pathogen interaction is discussed.

Abstract
Calmodulin (CaM), a ubiquitous intracellular calcium (Ca(2+)) sensor in all eukaryotic cells, is one of the well-known signaling proteins. Previously, CaM gene has shown a high transcriptional level in hemocyte of the pathogen infected shrimp, suggesting that shrimp CaM does not only regulate Ca(2+) metabolism, but is also involved in immune response cascade. In the present study, the CaM gene of shrimp Penaeus monodon was identified and the recombinant P.monodon CaM (rPmCaM) was produced and biochemically characterized. The identification of CaM-binding proteins was also performed. The PmCaM cDNA consisted of an open reading frame of 447 bp encoding for 149 amino acid residues with a calculated mass of 16,810 Da and an isoelectric point of 4.09. Tissue distribution showed that the PmCaM transcript was expressed in all examined tissues. The results of gel mobility shift assay, circular dichroism spectroscopy and fluorescence spectroscopy all confirmed that the conformational changes of the rPmCaM were observed after the calcium binding. According to the gene silencing of PmCaM transcript levels, the shrimp's susceptibility to pathogenic Vibrio harveyi infection increased in comparison with that of the control groups. Protein pull-down assay and LC-MS/MS analysis were performed to identify rPmCaM-binding proteins involved in shrimp immune responses and transglutaminase, elongation factor 1-alpha, elongation factor 2 and actin were found. However, by computational analysis, only the first three proteins contained CaM-binding domain. These findings suggested that PmCaM may play an important role in regulation of shrimp immune system.

Abstract
Rab3, a member of the Rab GTPase family, has been found to be involved in innate immunity. However, the precise function of this GTPase in innate immunity remains unknown. In this study, we identified a Rab3 gene (Ha-Rab3) from the cotton bollworm, Helicoverpa armigera and studied its roles in innate immune responses. Expression of Ha-Rab3 was upregulated in the hemocytes of H. armigera larvae after the injection of Escherichia coli or chromatography beads. The dsRNA-mediated knockdown of Ha-Rab3 gene in H. armigera larval hemocytes led to significant reduction in the phagocytosis and nodulation activities of hemocytes against E. coli, significant increase in the bacterial load in larval hemolymph, and significant reduction in the encapsulation activities of hemocytes toward invading chromatography beads. Furthermore, Ha-Rab3 knockdown significantly suppressed spreading of plasmatocytes. These results suggest that Ha-Rab3 plays important roles in H. armigera cellular immune responses, possibly by mediating spreading of hemocytes.

Abstract
Identification and characterization of the RNAi-related genes is the key to understanding RNAi mechanism in shrimp. In this study, we have identified and characterized a novel putative RNA helicase gene, Mj-mov-10 from the kuruma shrimp, Marsupenaeus japonicus and its implication in shrimp RNAi was demonstrated. The full-length Mj-mov-10 gene contained 3536bp, including 239 bp of 5'UTR, 2895 bp of the open reading frame (ORF) and 402bp of 3'UTR, respectively. An ORF of Mj-mov-10 could be translated to a 109-kDa protein which consists of a single helicase core domain containing seven signature motifs of the RNA helicase superfamily-1. Mj-MOV-10 protein shared 47% and 40% identity with mammalian MOV-10 and plant SDE3, respectively. Expression of Mj-mov-10 gene was significantly up-regulated upon dsRNA and white spot syndrome virus (WSSV) challenge. In vivo gene knockdown of Mj-mov-10 resulted in an increase of a susceptibility of shrimp to WSSV infection. Our results implied the functional significance of Mj-MOV-10 in dsRNA-mediated gene silencing and antiviral defense mechanism in shrimp.

Abstract
Rab GTPases, members of the Ras-like GTPase superfamily, are central elements in endocytic membrane trafficking. However, little is known of the Rab genes in the giant freshwater prawn Macrobrachium rosenbergii. In this study, 11 Rab genes were identified from M. rosenbergii. All MrRabs have a RAB domain. Phylogenetic analysis showed that these 11 MrRabs were divided into different groups. The MrRab genes were ubiquitously expressed in heart, hemocytes, hepatopancreas, gills, stomach, and intestines. Real-time polymerase chain reaction revealed that the MrRab genes were significantly upregulated by white spot syndrome virus (WSSV) in the prawns, indicating that MrRabs might play an important role in innate immune response against WSSV. Moreover, after challenge with Vibrio parahaemolyticus, the expression levels of all MrRabs in the hepatopancreas were also upregulated, which might indicated the involvement of MrRabs in prawns antibacterial immunity. In all, these preliminary results showed that MrRabs were involved in innate immunity of M. rosenbergii.

Abstract
Viral disease caused by the Yellow head virus (YHV) had great impact on economic loss in the aquaculture industry. Prevention or curing YHV disease is still not possible due to the lack of understanding of the basic mechanisms of YHV infection. In this report, the endocytosis inhibitors (chlorpromazine (CPZ), amiloride and methyl-β-cyclodextrin (MβCD)) were used to identify the cellular entry pathway of YHV. Pretreating shrimp with CPZ but not amiloride or MβCD followed by YHV challenge resulted in a significant reduction of YHV levels, suggesting that YHV entered the shrimp cells via clathrin-mediated endocytosis. Next, the major component of the clathrin-coated vesicle, Penaeus monodon clathrin heavy chain (PmCHC) was cloned and characterized. The complete coding sequence of PmCHC is 5055 bp encoding a putative protein of 1684 amino acids. Specific silencing of PmCHC mRNA by dsRNA-PmCHC showed an inhibition of YHV replication for 48 h post YHV injection as well as exhibiting a delay in shrimp mortality. These results indicated that PmCHC was an essential component for YHV infection of shrimp cells.

Abstract
Shrimp is one of the most important commercial marine species worldwide; however, viral diseases threaten the healthy development of shrimp aquaculture. In order to develop efficient control strategies against viral diseases, researchers have begun focusing increasing attention to the molecular mechanism of shrimp innate immunity. Although knowledge of shrimp humoral immunity has grown significantly in recent years, very little information is available about the cell-mediated immune responses. Several cellular processes such as phagocytosis, apoptosis, and RNA interference critical in cellular immune response play a significant role in endogenous antiviral activity in shrimp. In this review, we summarize the emerging research and highlight key mediators of cellular immune response to viral pathogens.

Abstract
The culture of penaeid shrimp is rapidly developing as a major business endeavor worldwide. However, viral diseases have caused huge economic loss in penaeid shrimp culture industries. Knowledge of shrimp innate immunity and antiviral responses has made important progress in recent years, allowing the design of better strategies for the prevention and control of shrimp diseases. In this study, we have updated information on shrimp antiviral immunity and interactions between shrimp hosts and viral pathogens. Current knowledge and recent progress in immune signaling pathways (e.g., Toll/IMD-NF-κB and JAK-STAT signaling pathways), RNAi, phagocytosis, and apoptosis in shrimp antiviral immunity are discussed. The mechanism of viral infection in shrimp hosts and the interactions between viruses and shrimp innate immune systems are also analyzed.

Abstract
Yellow head virus (YHV) is one of the most widespread viruses seriously affecting black tiger shrimp (Penaeus monodon) cultivation. A previous microarray study demonstrated that clathrin coat assembly protein 17 (AP17) was significantly up-regulated after YHV infection (Pongsomboon et al., 2011). Clathrin coat AP17 is a part of the assembly protein σ2 (AP-2) complex which is involved in clathrin-mediated endocytosis. Quantitative RT-PCR (qRT-PCR) revealed that the clathrin coat AP17 gene was up-regulated 3-fold at 12 h post YHV infection. In addition, immunofluorescence microscopy showed that clathrin coat AP17 was highly expressed in the cytoplasm of the YHV-infected hemocytes. Knockdown of the clathrin coat AP17 gene dramatically reduced YHV replicativity by 32-fold. Interestingly, shrimp pre-treated with chlorpromazine, a commercial drug that inhibits clathrin-dependent endocytosis, exhibited significantly low levels of YHV infection. Taken together, these results suggest that clathrin-mediated endocytosis is involved in YHV propagation in P. monodon.
