Front Microbiol 2023; 14:1233815. [PMID: 37637113 PMCID: PMC10450618 DOI: 10.3389/fmicb.2023.1233815] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2023] [Accepted: 07/28/2023] [Indexed: 08/29/2023] Open
Abstract
Although the microbial ecology of integrated rice-crayfish farming systems is receiving increasing attention with the expanding application area in China, the effects of rice transplanting patterns on the microbial community of water, sediment and Procambarus clarkii intestine in rice-crayfish system has yet to be determined. This study explored the microbial community present in water, sediment and intestine samples from three transplant patterns (rice crayfish with wide-narrow row transplanting, rice-crayfish with normal transplanting and pond-crayfish, abbreviated as RC-W, RC, and PC, respectively) using high-throughput sequencing. The results showed that the dominant microbial taxa from sediment, surrounding water, and intestine at phylum level were Proteobacteria, Chloroflexi, Cyanobacteria, Actinobacteria, Bacteroidetes. The patterns of rice transplanting had significant effects on microbial biodiversity and species composition in surrounding water. The OTUs community richness of water under RC group was significantly higher than that of PC group and RC-W group. The OTU relative abundance of top 10 operational taxonomic units had significantly different (p < 0.05) in the water samples from the three groups. The intestinal OTU community richness of Procambarus clarkii in the three groups was positively correlated with the community richness of water. The proximity between intestinal and water samples in PCA diagram indicated that their species composition was more similar. The results also showed that rice transplanting patterns can affect intestinal microbial biodiversity of Procambarus clarkii and the intestinal microbial biodiversity correlated with water bodies. Although the intestinal microbial diversity of crayfish in RC-W group was lower than that in RC group, the relative abundance of potential pathogenic bacteria, such as Vibrio, Aeromonas, in intestine of the crayfish in the RC-W group was significantly decreased under rice wide-narrow row transplanting model. Redundancy analysis revealed that environmental parameters, such as pH, DO, nitrate, which regulate the composition of microbial community structures. This study provides an understanding for microbial response to different rice transplanting pattern in rice-crayfish farming system.

Abstract
An infectious disease is the most apprehensive problem in aquaculture as it can lead to high mortality in aquatic organisms and massive economic loss. Even though significant progress has been accomplished in therapeutic, prevention, and diagnostic using several potential technologies, more robust inventions and breakthroughs should be achieved to control the spread of infectious diseases. MicroRNA (miRNA) is an endogenous small non-coding RNA that post-transcriptionally regulates the protein-coding genes. It involves various biological regulatory mechanisms in organisms such as cell differentiation, proliferation, immune responses, development, apoptosis, and others. Furthermore, an miRNA also acts as a mediator to either regulate host responses or enhance the replication of diseases during infection. Therefore, the emergence of miRNAs could be potential candidates for the establishment of diagnostic tools for numerous infectious diseases. Interestingly, studies have revealed that miRNAs can be used as biomarkers and biosensors to detect diseases, and can also be used to design vaccines to attenuate pathogens. This review provides an overview of miRNA biogenesis and specifically focuses on its regulation during infection in aquatic organisms, especially on the host immune responses and how miRNAs enhance the replication of pathogens in the organism. In addition to that, we explored the potential applications, including diagnostic methods and treatments, that can be employed in the aquaculture industry.

Joo Hong S, Hong Kim K. Effects of length and sequence of long double-stranded RNAs targeting ribonucleotide reductase 2 of white spot syndrome virus (WSSV) on protective efficacy against WSSV. J Invertebr Pathol 2023; 196:107869. [PMID: 36455669 DOI: 10.1016/j.jip.2022.107869] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Revised: 11/22/2022] [Accepted: 11/24/2022] [Indexed: 11/29/2022]
Abstract
Long double-stranded RNA (dsRNA)-mediated RNA interference (RNAi) has been a well-known mechanism against white spot syndrome virus (WSSV) in cultured shrimp. In the present study, we investigated the protective efficacy of dsRNAs targeting the ribonucleotide reductase 2 (rr2) gene of WSSV according to length and target sequence location. To produce different lengths of dsRNAs, the 640 bp rr2 fragment (fragment I) was split into two equal 320 bp fragments (fragment II and III), then each 320 bp fragment was redivided into two 160 bp fragments (fragment IV, V, VI, and VII). After the synthesis of seven kinds of dsRNA fragments, dsRNAs with the same length were mixed with each other, then used for the evaluation of dsRNA's length effect in Penaeus vannamei. The result showed that 160 bp long dsRNAs were as effective as 320 and 640 bp long dsRNAs in the protection of shrimp against WSSV infection, suggesting that the dsRNA length of 160 bp would be enough to be used as RNAi-mediated WSSV suppression in P. vannamei. However, as the 160 bp long dsRNAs used in the length effect experiment were not a single dsRNA population but a mixture of 160 bp dsRNA fragments covering the parent 640 bp long dsRNA, the sequence effect was not included in this RNAi efficacy. In the experiments to know the effect of not only length but also sequence of rr2-targeting long dsRNAs on the protective efficacy against WSSV, dsRNAs with a length of 640 bp (fragment I) and 320 bp (fragment II, III) showed a constant high defense ability, but the protection degree of long dsRNAs with a length of 160 bp was different depending on the kinds of the fragment, suggesting that the RNAi efficacy of some rr2-targeting long dsRNAs with a length of 160 bp might have sequences that are variable according to experimental conditions. In conclusion, this study showed that the protective ability of long dsRNAs in shrimp against WSSV infection can be affected by the length and sequence of the long dsRNAs.

Abstract
The incidence of emerging infectious diseases (EIDs) has increased in wildlife populations in recent years and is expected to continue to increase with global environmental change. Marine diseases are relatively understudied compared with terrestrial diseases but warrant parallel attention as they can disrupt ecosystems, cause economic loss, and threaten human livelihoods. Although there are many existing tools to combat the direct and indirect consequences of EIDs, these management strategies are often insufficient or ineffective in marine habitats compared with their terrestrial counterparts, often due to fundamental differences between marine and terrestrial systems. Here, we first illustrate how the marine environment and marine organism life histories present challenges and opportunities for wildlife disease management. We then assess the application of common disease management strategies to marine versus terrestrial systems to identify those that may be most effective for marine disease outbreak prevention, response, and recovery. Finally, we recommend multiple actions that will enable more successful management of marine wildlife disease emergencies in the future. These include prioritizing marine disease research and understanding its links to climate change, improving marine ecosystem health, forming better monitoring and response networks, developing marine veterinary medicine programs, and enacting policy that addresses marine and other wildlife diseases. Overall, we encourage a more proactive rather than reactive approach to marine wildlife disease management and emphasize that multidisciplinary collaborations are crucial to managing marine wildlife health.

Abstract
The mitogen-activated protein kinase (MAPK) intracellular signaling pathway mediates numerous biological processes, including antimicrobial immune response by inducing antimicrobial peptides (AMPs) production. Although MAPK signaling cascade proteins have been identified in penaeid shrimp, their modulation via the MKK4-p38-c-Jun cascade and effect on AMPs production is unknown. Here, we show that hemocyanin (PvHMC), antimicrobial peptides (anti-lipopolysaccharide factor, crustin, and penaeidins), and MKK4-p38-c-Jun cascade proteins are simultaneously induced by pathogens (Vibrio parahaemolyticus, Staphylococcus aureus, and white spot syndrome virus) in Penaeus vannamei. Intriguingly, knockdown of PvHMC with or without pathogen challenge attenuated the expression of MKK4-p38-c-Jun cascade proteins and their phosphorylation level, which consequently decreased AMPs expression. Further analysis revealed that PvHMC interacts via its armadillo (ARM) repeat domain with PvMKK4 to modulate the p38 MAPK signaling pathway. Thus, the ARM repeat domain enables penaeid shrimp hemocyanin to modulate AMPs expression during antimicrobial response by activating the p38 MAPK signaling pathway. Pathogens induce hemocyanin, MKK4-p38-c-Jun proteins, and antimicrobial peptide genes Hemocyanin modulates MKK4-p38-c-Jun cascade proteins to regulate AMPs gene expression Hemocyanin interacts with MKK4 to modulate p38 MAPK signaling in penaeid shrimp Deletion of the ARM repeat domain attenuates the interaction of hemocyanin with MKK4

Abstract
Survival rates of prawn, Macrobrachium rosenbergii, against Lactococcus garvieae, immune parameters, carbohydrate metabolism and biogenic amines were determined when the prawn were fed diets containing tyramine (TA) at the levels of 1 and 10 mg kg-1. Results showed that prawn fed diets containing TA for 3 days, challenged with L. garvieae, and then continuously fed individually tested diets had a significantly higher survival rate than those fed the control diet at 168 h after the challenge, in a dose-dependent manner. Results included significant increases in total haemocyte count (THC), granular cells (GCs), semigranular cells (SGCs), phenoloxidase (PO) activity, respiratory bursts (RBs), RBs per haemocyte, phagocytic activity, and clearance efficiency to L. garvieae. Significantly lower plasma glucose and lactate were observed in prawn fed with TA-containing diets for 3 days, a result consistent with increases in the survival rate of the challenge test and the haemolymph octopamine (OA) level. Haemolymph dopamine (DA), norepinephrine (NE), TA, and OA levels of prawn that were fed TA-supplemented diets increased significantly after 1 day, and OA level increased continuously until the third day with a dose-effect relationship. It is therefore concluded that TA can be absorbed from a TA-containing diet to elevate haemolymph TA level, inducing the release of DA, NE, and OA to maintain homeostasis. The higher, more extensive OA expression promoted carbohydrate metabolism and immune resistance in M. rosenbergii.

Abstract
VP28 is an envelope protein of White Spot Syndrome Virus (WSSV), which has been shown in previous studies to induce a high immune response in shrimp. VP28 has been produced in some host systems such as Escherichia coli, Bacillus subtilis, and Pichia pastoris as free protein. Here we showed a new strategy of anchoring VP28 on the Saccharomyces cerevisiae yeast surface and using the yeast cell extract combined with probiotic as an oral vaccine for shrimp farming. We have successfully constructed a recombinant yeast cell capable of expressing VP28 on the cell surface. The feeding diet combined with VP28 anchored yeast cell extract provided significant assurance to Litopenaeus vannamei, challenged by WSSV, resulting in a relative percent survival (RPS) of 87.10 ± 2.15%. Interestingly, the utilization of VP28 anchored yeast cell extract could enhance the efficiency of probiotic strains like Lactobacillus and Bacillus on shrimp farming. The results in both laboratory scales and field trials using extract of VP28 displaying Saccharomyces showed a growth-promoting effect in shrimp, assessed through average shrimp weight. Taken together, our results in this study demonstrated a new successful strategy of using yeast cell surface as a tool to produce VP28-based oral vaccine for shrimp aquaculture. KEY POINTS: • A new strategy of using VP28 antigen as anchored protein on S. cerevisiae yeast cell surface (S. cerevisiae::VP28) • The utilization of VP28 antigen and yeast as S. cerevisiae::VP28 extract enhanced potential protection of Litopenaeus vannamei against White Spot Syndrome Virus (RPS 87.10%) • The use of S. cerevisiae::VP28 extract increased efficiency of probiotic on shrimp growth-promoting effect either lab-scale or field trial.

Abstract
The shrimp aquaculture industry has encountered many diseases that have caused significant losses, with the most serious being white spot syndrome (WSS). Until now, no cures, vaccines, or drugs have been found to counteract the WSS virus (WSSV). The purpose of this study was to develop an oral delivery system to transport recombinant proteinaceous antigens into shrimp. To evaluate the feasibility of the oral delivery system, we used white shrimp as the test species and maggots as protein carriers. The results indicated that the target protein was successfully preserved in the maggot, and the protein was detected in the gastrointestinal tract of the shrimp, showing that this oral delivery system could deliver the target protein to the shrimp intestine, where it was absorbed. In addition, the maggots were found to increase the total haemocyte count and phenoloxidase activity of the shrimp, and feeding shrimp rVP24-fed maggots significantly induced the expression of penaeidins 2. In the WSSV challenge, the survival rate of rVP24-fed maggots was approximately 43%. This study showed that maggots can be used as effective oral delivery systems for aquatic products and may provide a new method for aquatic vaccine delivery systems.

Abstract
Ficolin is classified as an immune related protein containing collagen-like and fibrinogen-related domain (FreD). In invertebrates, the functions of fibrinogen-related proteins (FrePs) are of importance to innate immunity. In this study, a FreP in the black tiger shrimp Penaeus monodon was identified and characterized. The PmFreP cDNA is 1,007 bp long with a 921 bp-open reading frame that encodes for 306 amino acids. The deduced PmFreP sequence consists of a signal peptide, an unknown region and the FreD. Phylogenetic analysis showed that PmFreP was clustered with fibrinogen-like proteins in crustaceans which was separated from vertebrate ficolin-like proteins. The deduced fibrinogen-like domain contains four conserved cysteine residues (Cys96, Cys127, Cys249, and Cys262) that are responsible for the formation of disulfide bridges. Gene expression analysis shows that Pmfrep is mainly expressed in the intestine and the expression is significantly upregulated after Vibrio harveyi and white spot syndrome virus (WSSV) challenge. Recombinant PmFreP (rPmFreP) were successfully expressed and purified, and forms a trimeric structure as judged by native-PAGE. Bacterial binding assay showed that the rPmFreD can bind and agglutinate Gram-negative and Gram-positive bacteria in the presence of calcium (Ca2+) ions. Moreover, the rPmFreP facilitates the clearance of V. harveyi in vivo. Overall, our results suggested that the PmFreP may serve as pattern recognition receptors implicated in shrimp innate immunity.

Abstract
Surface display can expose foreign antigenic protein on the surface of the vaccine vector, which is promising choice to elicit better immune responses. In this study, we apply this strategy to develop an immunoactivator by using a live attenuated Vibrio harveyi as an antigenic protein carrier with surface displayed VP28, a major envelope protein of white spot syndrome virus (WSSV), for two major pathogens of Litopenaeus vannamei. As a result, the immunoactivator showed self-limited growth and attenuation of virulence in shrimp via different inoculation routes either with single-repetitive dose or high dose. Moreover, either intramuscular injection or oral administration of the immunoactivator did not affect growth of shrimp body weight or cause pathologic changes. Additionally, the rapid immunoprotection was induced by the immunoactivator after administration for one week with highly relative percent survival (RPS) more than 90% against both V. harveyi and WSSV. Until 4 weeks post administration, the immunoactivator still possessed efficient immune effect with no less than 60% RPS for both pathogens. Totally, the attenuated V. harveyi surface displaying VP28 could be a potential immunoactivator for WSSV and vibriosis control in L. vannamei.

Alginate from Sargassum siliquosum Simultaneously Stimulates Innate Immunity, Upregulates Immune Genes, and Enhances Resistance of Pacific White Shrimp (Litopenaeus vannamei) Against White Spot Syndrome Virus (WSSV).

Abstract
Although alginate is known as an immunostimulant in shrimp, the comprehensive and simultaneous study on its activity to resolve the relationship of the hematological parameters, upregulation of immune-related gene expression, and resistance to pathogen has not been found in shrimp. We performed experiments to evaluate the effect and mechanism of alginate from S. siliquosum on Pacific white shrimp immune system. Hematological parameters were examined after oral administration of Na alginate in the shrimp. White spot syndrome virus (WSSV) was injected to the shrimp at 14 days, and its copy number was examined quantitatively (qRT-PCR). Immune-related gene expression was evaluated by qRT-PCR. Alginate increased some hematological immune parameters of shrimp. Before WSSV infection, expression levels of Toll and lectin genes were upregulated. The lectin gene were upregulated post infection, and the Toll gene in all the treatments were downregulated, except the shrimps fed with alginate at 6.0 g kg-1 at 48 h post infection (hpi). The shrimps fed with alginate at 6.0 g kg-1 were the most resistant and gave the least WSSV copy number at 48 hpi. Resistance of shrimps fed the alginate-supplemented diets against WSSV was significantly higher compared to that of the control treatment with 56% and 10% of survival rates, respectively. Oral administration of alginate did not affect the growth and total protein plasma. At 120 h post challenge, alginate treatment at 6.0 g kg-1 exhibited the highest survival rate. It is concluded that oral administration of alginate enhanced the innate immunity by upregulating immune-related gene expression. Consequently, the enhancement of the shrimp innate immunity improves the resistance against WSSV infection.

Abstract
In most species, variation in age among individuals is the strongest and most visible form of phenotypic variation. Individual-level age effects on disease traits, caused by differences in the age at exposure of the host or its parents, have been widely documented in invertebrates. They can influence diverse traits, such as host susceptibility, virulence, parasite reproduction and further transmission, and may cascade to the population level, influencing disease prevalence and within-host competition. Here, I summarize what is known about the relationship between individual-level age/stage effects and infectious disease in invertebrates. I also attempt to link age effects to the theory of aging (senescence), and highlight the importance of population age structure to disease epidemiology and evolution. I conclude by identifying gaps in our understanding of individual- and population-level age effects in invertebrates. As the age structure of populations varies across space and time, age effects have strong epidemiological, ecological, and evolutionary implications for explaining variation in infectious diseases of invertebrates.

Abstract
Invertebrate immune response may be primed by a current infection in a sustained manner, leading to the failure of a secondary infection with the same pathogen. The present study focuses on the Schistosomiasis vector snail Biomphalaria glabrata, in which a specific genotype-dependent immunological memory was demonstrated as a shift from a cellular to a humoral immune response. Herein, we investigate the complex molecular bases associated with this genotype-dependant immunological memory response. We demonstrate that Biomphalaria regulates a polymorphic set of immune recognition molecules and immune effector repertoires to respond to different strains of Schistosoma parasites. These results suggest a combinatorial usage of pathogen recognition receptors (PRRs) that distinguish different strains of parasites during the acquisition of immunological memory. Immunizations also show that snails become resistant after exposure to parasite extracts. Hemolymph transfer and a label-free proteomic analysis proved that circulating hemolymph compounds can be produced and released to more efficiently kill the newly encountered parasite of the same genetic lineage.

Abstract
Recent studies have shown that hemocyanin plays immune-related functions apart from its canonical respiratory function. While shrimp hemocyanin is found to generate antimicrobial peptides, antiviral related peptides have not been reported. In the present study, the serum of white spot syndrome virus (WSSV) infected Litopenaeus vannamei analyzed by two-dimensional gel electrophoresis, revealed 45 consistently down-regulated protein spots and 10 up-regulated protein spots. Five of the significantly up-regulated spots were identified as hemocyanin derived peptides. One of the five peptides, designated LvHcL48, was further characterized by analyzing its primary sequence via Edman N-terminal sequencing, C-terminal sequencing and amino acid sequence alignment. LvHcL48 was found to be a 79 amino acid fragment (aa584-662) from the C-terminal domain of L. vannamei hemocyanin protein (ADZ15149). Both in vivo and in vitro functional studies revealed that LvHcL48 has immunological activities, as recombinant LvHcL48 protein (rLvHcL48) significantly inhibited the transcription of the WSSV genes wsv069 and wsv421 coupled with a significant reduction in WSSV copy numbers. Further analysis showed that LvHcL48 could interact with the WSSV envelope protein 28 (VP28). Our present data therefore reveals the generation of an antiviral hemocyanin derived peptide LvHcL48 from WSSV infected shrimp, which binds to the envelope protein VP28 of WSSV.

The silkrose of Bombyx mori effectively prevents vibriosis in penaeid prawns via the activation of innate immunity. Sci Rep 2018; 8:8836.

Abstract
We previously identified novel bioactive polysaccharides from Bactrocera cucurbitae and Antheraea yamamai that activate innate immunity in RAW264 murine macrophages. However, in terms of potential applications in the cultivation of prawns, there were problems with the availability of these insects. However, we have now identified a polysaccharide from Bombyx mori that activates innate immunity in RAW264 cells and penaeid prawns. This purified polysaccharide, termed silkrose of B. mori (silkrose-BM), has a molecular weight of 1,150,000 and produces a single symmetrical peak on HPLC. Eight of nine constitutive monosaccharides of silkrose-BM are concomitant with dipterose of B. cucurbitae (dipterose-BC) and silkrose of A. yamamai (silkrose-AY). The major differences are found in the molar ratios of the monosaccharides. Silkrose-BM is approximately 500-fold less potent than silkrose-AY (EC50: 2.5 and 0.0043 μg/mL, respectively) in a nitrite oxide (NO) production assay using RAW264 cells. However, the maximum NO production for silkrose-BM and AY were comparable and higher than that of the lipopolysaccharide of Escherichia coli. The survival of penaeid prawns (Litopenaeus vannamei and Marsupenaeus japonicus) after infection with Vibrio penaecida was significantly improved by both dietary silkrose-BM and B. mori pupae. This suggests that silkrose-BM effectively prevents vibriosis in penaeid prawns via the activation of innate immunity.

Abstract
The farming of edible insects is an alternative strategy for the production of protein-rich food and feed with a low ecological footprint. The industrial production of insect-derived protein is more cost-effective and energy-efficient than livestock farming or aquaculture. The mealworm Tenebrio molitor is economically among the most important species used for the large-scale conversion of plant biomass into protein. Here, we review the mass rearing of this species and its conversion into food and feed, focusing on challenges such as the contamination of food/feed products with bacteria from the insect gut and the risk of rapidly spreading pathogens and parasites. We propose solutions to prevent the outbreak of infections among farmed insects without reliance on antibiotics. Transgenerational immune priming and probiotic bacteria may provide alternative strategies for sustainable insect farming.

Abstract
In the last decade, a paradigm shift has emerged in comparative immunology. Invertebrates can no longer be considered to be devoid of specific recognition and immune memory. However, we still lack a comprehensive view of these phenomena and their molecular mechanisms across phyla, especially in terms of duration, specificity, and efficiency in a natural context. In this study, we focused on a Lophotrochozoan/virus interaction, as antiviral priming is mostly overlooked in molluscs. Juvenile Crassostrea gigas oysters experience reoccurring mass mortalities events from Ostreid herpes virus 1 with no existing therapeutic treatment. Our results showed that various nucleic acid injections can prime oysters to trigger an antiviral state ultimately protecting them against a subsequent viral infection. Focusing on poly(I:C) as elicitor, we evidenced that it protected from an environmental infection, by mitigating viral replication. That protection seemed to induce a specific antiviral response as poly(I:C) fails to protect against a pathogenic bacteria. Finally, we showed that this phenomenon was long-lasting, persisting for at least 5 months thus suggesting for the first time the existence of innate immune memory in this invertebrate species. This study strengthens the emerging hypotheses about the broad conservation of innate immune priming and memory mechanisms in Lophotrochozoans.

Abstract
C-type lectins are pattern recognition proteins that play important roles in innate immunity in invertebrates by mediating the recognition of pathogens. In this study, a novel C-type lectin gene, PmCLec, was cloned and characterized from the black tiger shrimp Penaeus monodon. The open reading frame of PmCLec is 657 bp in length. It encodes a predicted protein of 218 amino acids with a calculated molecular mass and an isoelectric point of 24086 Da and 4.67, respectively. Sequence analysis of PmCLec showed similarity to members of the C-type lectin gene superfamily. The deduced protein contains a single carbohydrate recognition domain (CRD) and four conserved cysteine residues (Cys58, Cys126, Cys141, Cys149) that are involved in the formation of disulfide bridges. PmCLec transcripts are expressed in various tiger shrimp tissues, with the highest expression in the lymphoid organ. RNAi-mediated silencing of PmCLec resulted in higher cumulative mortality of knockdown shrimp after Vibrio harveyi infection compared to the control groups. Recombinant PmCLec was successfully expressed in the E. coli system. In the presence of Ca2+, purified rPmCLec protein binds and agglutinates Gram-positive bacteria (Staphylococcus aureus, S. hemolyticus), but only slightly binds and agglutinates E. coli and could not bind to the Gram-negative bacteria Bacillus megaterium and Vibrio harveyi. These results suggest that PmCLec functions as a pattern recognition receptor that is implicated in shrimp innate immunity.

Abstract
The arthropod Down syndrome cell adhesion molecule (Dscam) mediates pathogen-specific recognition via an extensive protein isoform repertoire produced by alternative splicing. To date, most studies have focused on the subsequent pathogen-specific immune response, and few have investigated the entry into cells of viruses or endosymbionts. In the present study, we cloned and characterized the cDNA of Laodelphax striatellus Dscam (LsDscam) and investigated the function of LsDscam in rice stripe virus (RSV) infection and the influence on the endosymbiont Wolbachia. LsDscam displayed a typical Dscam domain architecture, including 10 immunoglobulin (Ig) domains, six fibronectin type III domains, one transmembrane domain and a cytoplasmic tail. Alternative splicing occurred at the N-termini of the Ig2 and Ig3 domains, the complete Ig7 domain, the transmembrane domain and the C-terminus, comprising 10, 51, 35, two and two variable exons, respectively. Potentially LsDscam could encode at least 71 400 unique isoforms and 17 850 types of extracellular regions. LsDscam was expressed in various L. striatellus tissues. Knockdown of LsDscam mRNA via RNA interference decreased the titres of both RSV and Wolbachia, but did not change the numbers of the extracellular symbiotic bacterium Acinetobacter rhizosphaerae. Specific Dscam isoforms may play roles in enhancing the infection of vector-borne viruses or endosymbionts.

Abstract
A newly isolated Pacific white shrimp (Litopenaeus vannamei) beta-actin promoter SbaP and its derivative compact construct SbaP (ENX) have recently been demonstrated to promote ectopic gene expression in vitro and in vivo. To further explore the potential transduction application, this newly isolated shrimp promoter SbaP was comparatively tested with cytomegalovirus (CMV), simian virus 40 (SV40), polyhedrin (Polh), and white spot syndrome virus immediate early gene 1 (WSSV ie1) four constitutive promoters and a beta-actin promoter (TbaP) from tilapia fish to characterize its promoting function in eight different cell lines. Luciferase quantitation assays revealed that SbaP can drive luciferase gene expression in all eight cell lines including sf21 (insect), PAC2 (zebrafish), EPC (carp), CHSE-214 (chinook salmon), GSTEF (green sea turtle), MS-1 (monk seal), 293T (human), and HeLa (human), but at different levels. Comparative analysis revealed that the promoting activity of SbaP was lower (≤10-fold) than CMV but higher (2-20 folds) than Polh in most of these cell lines tested. Whereas, SbaP mediated luciferase expression in sf21 cells was over 20-fold higher than CMV, SV40, Polh, and TbaP promoter. Compared to the SbaP, SbaP (ENX), which was constructed on the basis of SbaP by deletion of two "negative" regulatory elements, exhibited no significant change of promoting activity in EPC and PAC2 cells, but a 5 and 16 % lower promoting effect in 293T and HeLa cells, respectively. Additionally, a recombinant baculovirus was constructed under the control of SbaP (ENX), and efficient promoter activity of newly generated baculoviral vector was detected both in vitro of infected sf21 cells and in vivo of injected indicator shrimp. These results warrant the potential application of SbaP, particularly SbaP (ENX) in ectopic gene expression in future.

Abstract
White spot syndrome virus (WSSV) is one of the most devastating viral pathogens of cultured shrimp worldwide. Recently published papers show the ability of WSSV structural protein VP28 to vaccinate shrimp and raise protection against the virus. This study attempted to identify the joining proteins of the aforementioned shrimp quasi-immune response by proteomic analysis. The other envelope protein, VP36B, was used as the non-protective subunit vaccine control. Shrimp were intramuscularly injected with rVPs or PBS on day 1 and day 4 and then on day 7 their gill tissues were sampled. The two-dimensional electrophoresis (2-DE) patterns of gill proteins between vaccinated and PBS groups were compared and 20 differentially expressed proteins identified by mass spectrometry, some of which were validated in gill and hemocyte tissues using real-time quantitative RT-PCR. Many of identified proteins and their expression levels also linked with the shrimp response during WSSV infection. The list of up-regulated protein spots found exclusively in rVP28-vaccinated shrimp include calreticulin and heat shock protein 70 with chaperone properties, ubiquitin, and others. The two serine proteases, chymotrypsin and trypsin, were significantly increased in shrimp of both vaccinated groups compared to PBS controls. The information presented here should be useful for gaining insight into invertebrate immunity.
