Abstract
Antibiotics are employed worldwide to treat diseases of humans and other animals, but most antibiotics and their secondary metabolites are discharged into the aquatic environment, and these pollutants are emerging as a severe threat to human health. However, the systematic effects of dietary antibiotics on intestinal health in crustaceans and the associated risk to human health have not been thoroughly investigated, especially the effects on growth, immune responses, intestinal health, and the abundance of antibiotic residues and antibiotic resistance genes (ARGs). In the present work, two typical antibiotics (sulfamethoxazole and oxytetracycline) were administered orally to juvenile oriental river prawn (Macrobrachium nipponense) for eight weeks to mimic long-term use of antibiotics at legal aquaculture doses. The results indicate that dietary exposure to antibiotics significantly inhibited the growth performance of prawns, suppressed immunological parameters, and caused higher mortality in prawns challenged with Aeromonas hydrophila. Furthermore, prawns fed a diet containing antibiotics displayed a decrease in the number of intestinal goblet cells and lower digestive enzyme activity, as well as impaired intestine antioxidant ability and immune responses. Additionally, redundancy analysis revealed that different dominant bacterial phyla were responsible for increased ARG abundance in the prawn intestinal tract between control and antibiotic diet groups. The health risks posed by antibiotic residues in prawn muscle were also evaluated. Our findings demonstrate the risk posed by long-term use of dietary antibiotics in prawns, and suggest that antibiotics should be administered more carefully during aquaculture.

Abstract
Octopus maya is a valuable endemic species of the Yucatán Peninsula (YP). This area can be divided into distinct regions depending on the presence of cold waters associated to upwelling events during spring and summer. This study was designed to determine if the physiological and immunological condition of O. maya show a relationship with variation of the sea surface temperature associated with the seasonal upwelling. A total of 117 organisms were collected from February to July in three fishing zones: Ría Lagartos located in the upwelling zone; Seybaplaya corresponding to the non-upwelling zone, and Sisal, the transitional zone. The organisms were examined in terms of physiological (total weight, the weight of the gonad and digestive gland, osmotic pressure, hemocyanin, protein, glucose, and cholesterol concentrations in plasma), and immunological variables (total hemocyte count, hemagglutination, phenoloxidase system activity, total phenoloxidase plasma activity, and lysozyme activity). Multivariate one-way ANOVA showed overall significant differences between groups of octopus by month/zone of capture, indicating that the physiological-immunological condition of O. maya is related to a temperature gradient. Wild octopuses captured at the upwelling zone and the transitional zone (Ría Lagartos and Sisal) in February, March, and April -with temperatures lower than 27°C- were in better conditions: larger size, high concentrations of hemocyanin, and low activity of the phenoloxidase system. Octopuses captured in the warmer waters (28–30°C) of the non-upwelling and transitional zones (Seybaplaya and Sisal) during June and July, could be reflecting the metabolic stress through immunological compensation mechanisms with higher activity of the phenoloxidase system, despite having a lower concentration of hemocytes, hemocyanin, and proteins. Although the movement of individual O. maya along the YP throughout their life cycle has not yet been determined, direct development and benthic behavior could limit the mobility of the organisms in such a way that their physiological and immunological condition might reflect adaptation to the regional environment. This information could help understand the performance of octopuses in their distribution area, which sustains an important fishery.

Abstract
The shrimp aquaculture industry is plagued by disease. Due to the lack of deep understanding of the relationship between innate immune mechanism and environmental adaptation mechanism, it is difficult to prevent and control the diseases of shrimp. The shrimp innate immune system has received much recent attention, and the functions of the humoral immune response and the cellular immune response have been preliminarily characterized. The role of environmental stress in shrimp disease has also been investigated recently, attempting to clarify the interactions among the innate immune response, the environmental stress response, and disease. Both the innate immune response and the environmental stress response have a complex relationship with shrimp diseases. Although these systems are important safeguards, allowing shrimp to adapt to adverse environments and resist infection, some pathogens, such as white spot syndrome virus, hijack these host systems. As shrimp lack an adaptive immune system, immunization therapy cannot be used to prevent and control shrimp disease. However, shrimp diseases can be controlled using ecological techniques. These techniques, which are based on the innate immune response and the environmental stress response, significantly reduce the impact of shrimp diseases. The object of this review is to summarize the recent research on shrimp environmental adaptation mechanisms, innate immune response mechanisms, and the relationship between these systems. We also suggest some directions for future research.

Abstract
The effect of Spirulina dried powder (SDP) on the immune response of white shrimp Litopenaeus vannamei was studied in vitro and in vivo. Incubating shrimp haemocytes in 0.5 mg ml(-1) SDP caused the degranulation of haemocytes and a reduction in the percentage of large cells within 30 min. Shrimp haemocytes incubated in 1 mg ml(-1) SDP significantly increased their phenoloxidase (PO) activity, serine proteinase activity, and respiratory burst activity (RB, release of superoxide anion). A recombinant protein of lipopolysaccharide and β-1,3-glucan binding protein (LGBP) of the white shrimp was produced, named rLvLGBP, and examined for its binding with SDP. An ELISA binding assay showed that rLvLGBP binds to SDP with a dissociation constant of 0.0507 μM. In another experiment, shrimp fed diets containing SDP at 0 (control), 30, and 60 g kg(-1) after four weeks were examined for LGBP transcript level and lysozyme activity, as well as phagocytic activity, clearance efficiency, and resistance to Vibrio alginolyticus. These parameters were significantly higher in shrimp receiving diets containing SDP at 60 g kg(-1) or 30 g kg(-1) than in controls. In conclusion, shrimp haemocytes receiving SDP provoked the activation of innate immunity as evidenced by the recognition and binding of LGBP, degranulation of haemocytes, reduction in the percentage of large cells, increases in PO activity, serine proteinase activity, superoxide anion levels, and up-regulated LGBP transcript levels. Shrimp receiving diets containing SDP had increased lysozyme activity and resistance against V. alginolyticus infection. This study showed the mechanism underlying the immunostimulatory action of Spirulina and its immune response in shrimp.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2016; 55:144-51.

Abstract
Lipopolysaccharide and β-1,3-glucan-binding protein (LGBP), important pattern recognition proteins (PRPs), recognize lipopolysaccharide (LPS) and β-1,3-glucan (βG), known as pathogen-associated molecular patterns (PAMPs), and subsequently trigger innate immunity. Several seaweed polysaccharides and seaweed extracts increase immune parameters and resistance to pathogens. Here, we constructed the expression vector pET28b-LvLGBP and transferred it into Escherichia coli BL21 (DE3) for protein expression and to produce the recombinant protein LGBP (rLvLGBP) in white shrimp Litopenaeus vannamei. We examined the binding of rLvLGBP with seaweed-derived polysaccharides including alginate, carrageenan, fucoidan, laminarin, Gracilaria tenuistipitata extract (GTE), and Sargassum duplicatum extract (SDE), and examined the phenoloxidase activity of shrimp haemocytes incubated with a mixture of rLvLGBP and each polysaccharide. We also examined the binding of rLvLGBP with LPS and βG, and the phenoloxidase activity of shrimp haemocytes incubated with a mixture of rLvLGBP and LPS (rLvLGBP-LPS) or a mixture of rLvLGBP and βG (rLvLGBP-βG). An ELISA binding assay indicated that rLvLGBP binds to LPS, βG, alginate, carrageenan, fucoidan, laminarin, GTE, and SDE with dissociation constants of 0.1138-0.1770 μM. Furthermore, our results also indicated that the phenoloxidase activity of shrimp haemocytes incubated with a mixture of rLvLGBP and LPS, βG, alginate, carrageenan, fucoidan, laminarin, GTE, and SDE significantly increased by 328%, 172%, 200%, 213%, 197%, 194%, 191%, and 197%, respectively compared to controls (cacodylate buffer). We conclude that LvLGBP functions as a PRP, recognizes and binds to LPS, βG, alginate, carrageenan, fucoidan, laminarin, GTE, and SDE, and subsequently leads to activating innate immunity in shrimp.

FISH & SHELLFISH IMMUNOLOGY 2016; 48:196-205.

Abstract
β-1, 3 glucan binding protein (β-GBP) was isolated from the haemocytes of blue swimmer crab, Portunus pelagicus and purified by laminarin coupled Sephadex G-100 affinity column chromatography. The purified β-GBP has the molecular mass of 100 kDa, confirmed by SDS-PAGE. The X-ray diffraction analysis of purified β-GBP indicates the crystalline nature of the protein and also the presence of single peak confirming the existence of β-glucan molecule. The results of agglutination assay showed that the purified β-GBP had the ability to agglutinate with yeast cell, Saccharomyces cerevisiae and mammalian erythrocytes. β-GBP can agglutinate with yeast cells at the concentration of 50 μg/ml. The phagocytic and encapsulation activity of purified β-GBP from P. pelagicus was determined with yeast cell S. cerevisiae and sepharose bead suspension respectively. This reveals that, β-GBP have the ability to detect the pathogen associated molecular patterns (PAMP) found on the surface of fungi and bacteria. The recognition of invading foreign substances and in the involvement of functional activities induces the activation of prophenoloxidase. This revealed that β-GBP play a major role in the innate immune system of crustaceans by stimulating the prophenoloxidase system. Moreover, it was obvious to note that β-GBP reaction product exhibited antibacterial and antibiofilm activity against Gram positive and Gram negative bacteria. This study concludes the functional aspects of β-GBP purified from P. pelagicus and its vital role in the stimulation of prophenoloxidase cascade during the pathogenic infection.

Abstract
Recognition of pathogens by insect pattern recognition receptors is critical to mount effective immune responses. In this study, we reported a new member (βGRP3) of the β-1, 3-glucan recognition protein (βGRP) family from the tobacco hornworm Manduca sexta. Unlike other members of the M. sexta βGRP family proteins, which contain an N-terminal small glucan binding domain and a C-terminal large glucanase-like domain, βGRP3 is 40-45 residues shorter at the N-terminus and lacks the small glucan binding domain. The glucanase-like domain of βGRP3 is most similar to that of M. sexta microbe binding protein (MBP) with 78% identity. βGRP3 transcript was mainly expressed in the fat body, and both its mRNA and protein levels were not induced by microorganisms in larvae. Recombinant βGRP3 purified from Drosophila S2 cells could bind to several Gram-negative and Gram-positive bacteria and yeast, as well as to laminarin (β-1, 3-glucan), mannan, lipopolysaccharide (LPS), lipoteichoic acid (LTA), and meso-diaminopimelic acid (DAP)-type peptidoglycan (PG), but did not bind to Lysine-type PG. Binding of βGRP3 to laminarin could be competed well by free laminarin, mannan, LPS and LTA, but almost not competed by free PGs. Recombinant βGRP3 could agglutinate Bacillus cereus and Escherichia coli in a calcium-dependent manner and showed antibacterial (bacteriostatic) activity against B. cereus, novel functions that have not been reported for the βGRP family proteins before. M. sexta βGRP3 may serve as an immune surveillance receptor with multiple functions.

Abstract
A β-1, 3-Glucan binding protein (β-GBP) was isolated from green tiger shrimp Penaeus semisulcatus and purified using laminarin precipitation and affinity chromatography on laminarin-Sepharose 6B column respectively. P. semisulcatus β-GBP exhibits a single band with a molecular weight of 112 kDa on SDS-PAGE and pI of 5.9 in isoelectric focusing (IEF). Negative staining of P. semisulcatus β-GBP showed large aggregates with crystalline surface when viewed by Electron Microscopy. Circular dichroism spectra of P. semisulcatus β-GBP showed broad negative minimum wavelength extending from 200 to 250 nm can be attributed to the presence of β-sheets in its secondary structure. P. semisulcatus β-GBP comprises the specific binding affinity with the polysaccharide β-1, 3-glucans (laminarin), this recognition and binding leads to the activation of prophenoloxidase cascade. Interestingly, P. semisulcatus β-GBP also involved in the agglutination of baker's yeast, bacteria, erythrocytes (RBCs) and enhances the PO activity. Herein, we have investigated the importance of β-GBP in innate immune response of P. semisulcatus and they implicate the evolutionary link with similar proteins found in other invertebrates.

Abstract
The major hindrance in the development and sustainability of aquaculture industry is the occurrence of various diseases in the farming systems. Today, preventive and management measures are central concern to overcome such outbreak of diseases. Immunostimulants are considered as an effective tool for enhancing immune status of cultured organisms. Among different immunostimulants used in aquaculture practices, β-glucan is one of the promising immunostimulant, which is a homopolysaccharide of glucose molecule linked by the glycoside bond. It forms the major constituents of cell wall of some plants, fungi, bacteria, mushroom, yeast, and seaweeds. Major attention on β-glucan was captivated with the gain in knowledge on its receptors and the mechanism of action. The receptor present inside the animal body recognizes and binds to β-glucan, which in turn renders the animal with high resistance and enhanced immune response. This review highlights β-glucan as an immunostimulant, its effective dosages, and route of administration and furthermore provides an outline on role of β-glucan in enhancing growth, survival, and protection against infectious pathogens pertaining to fishes and shellfishes. Study also summarizes the effect of β-glucan on its receptors, recognition of proteins, immune-related enzymes, immune-related gene expression and their mechanisms of action.

Identification of a serine proteinase homolog (Sp-SPH) involved in immune defense in the mud crab Scylla paramamosain. PLoS One 2013; 8:e63787.

Abstract
Clip domain serine proteinase homologs are involved in many biological processes including immune response. To identify the immune function of a serine proteinase homolog (Sp-SPH), originally isolated from hemocytes of the mud crab, Scylla paramamosain, the Sp-SPH was expressed recombinantly and purified for further studies. It was found that the Sp-SPH protein could bind to a number of bacteria (including Aeromonas hydrophila, Escherichia coli, Staphylococcus aureus, Vibrio fluvialis, Vibrio harveyi and Vibrio parahemolyticus), bacterial cell wall components such as lipopolysaccharide or peptidoglycan (PGN), and β-1, 3-glucan of fungus. But no direct antibacterial activity of Sp-SPH protein was shown by using minimum inhibitory concentration or minimum bactericidal concentration assays. Nevertheless, the Sp-SPH protein was found to significantly enhance the crab hemocyte adhesion activity (paired t-test, P<0.05), and increase phenoloxidase activity if triggered by PGN in vitro (paired t-test, P<0.05). Importantly, the Sp-SPH protein was demonstrated to promote the survival rate of the animals after challenge with A. hydrophila or V. parahemolyticus which were both recognized by Sp-SPH protein, if pre-incubated with Sp-SPH protein, respectively. Whereas, the crabs died much faster when challenged with Vibrio alginolyiicus, a pathogenic bacterium not recognized by Sp-SPH protein, compared to those of crabs challenged with A. hydrophila or V. parahemolyticus when pre-coated with Sp-SPH protein. Taken together, these data suggested that Sp-SPH molecule might play an important role in immune defense against bacterial infection in the mud crab S. paramamosain.

Abstract
The global shrimp industry still faces various serious disease-related problems that are mainly caused by pathogenic bacteria and viruses. Understanding the host defense mechanisms is likely to be beneficial in designing and implementing effective strategies to solve the current and future pathogen-related problems. Melanization, which is performed by phenoloxidase (PO) and controlled by the prophenoloxidase (proPO) activation cascade, plays an important role in the invertebrate immune system in allowing a rapid response to pathogen infection. The activation of the proPO system, by the specific recognition of microorganisms by pattern-recognition proteins (PRPs), triggers a serine proteinase cascade, eventually leading to the cleavage of the inactive proPO to the active PO that functions to produce the melanin and toxic reactive intermediates against invading pathogens. This review highlights the recent discoveries of the critical roles of the proPO system in the shrimp immune responses against major pathogens, and emphasizes the functional characterizations of four major groups of genes and proteins in the proPO cascade in penaeid shrimp, that is the PRPs, serine proteinases, proPO and inhibitors.

Abstract
Invertebrates, including shrimp, have developed very complicated innate immune system against pathogens. Much work has been performed on the innate immunity of shrimp, including immune recognition, signal transduction, effector molecules and antiviral responses due to its great economic value. Pattern recognition is the first step of innate immunity. Pattern recognition receptors (PRRs) sense the presence of infection and activate immune responses. The studies on shrimp PRRs revealed the recognition mechanism of shrimp at a certain degree. To date, 11 types of pattern recognition receptors (PRRs) have been identified in shrimp, namely, β-1,3-glucanase-related proteins, β-1,3-glucan-binding proteins, C-type lectins, scavenger receptors, galectins, fibrinogen-related proteins, thioester-containing protein, Down syndrome cell adhesion molecule, serine protease homologs, trans-activation response RNA-binding protein and Toll like receptors. A number of PRRs have been functionally studied and have been found to have different binding specificities and immune functions. The present review aims to summarize the current knowledge on the PRRs of shrimp.

Abstract
The ridgetail white prawn Exopalaemon carinicauda is one of the most important commercial species in eastern China. However, little information of immune genes in E. carinicauda has been reported. To identify distinctive genes associated with immunity, an expressed sequence tag (EST) library was constructed from hemocytes of E. carinicauda. A total of 3411 clones were sequenced, yielding 2853 ESTs and the average sequence length is 436 bp. The cluster and assembly analysis yielded 1053 unique sequences including 329 contigs and 724 singletons. Blast analysis identified 593 (56.3%) of the unique sequences as orthologs of genes from other organisms (E-value < 1e-5). Based on the COG and Gene Ontology (GO), 593 unique sequences were classified. Through comparison with previous studies, 153 genes assembled from 367 ESTs have been identified as possibly involved in defense or immune functions. These genes are categorized into seven categories according to their putative functions in shrimp immune system: antimicrobial peptides, prophenoloxidase activating system, antioxidant defense systems, chaperone proteins, clottable proteins, pattern recognition receptors and other immune-related genes. According to EST abundance, the major immune-related genes were thioredoxin (141, 4.94% of all ESTs) and calmodulin (14, 0.49% of all ESTs). The EST sequences of E. carinicauda hemocytes provide important information of the immune system and lay the groundwork for development of molecular markers related to disease resistance in prawn species.

FISH & SHELLFISH IMMUNOLOGY 2012; 33:962-968. [PMID: 22971348 DOI: 10.1016/j.fsi.2012.08.004] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/02/2012] [Revised: 08/06/2012] [Accepted: 08/08/2012] [Indexed: 06/01/2023]
Abstract
The total (THC) and differential haemocyte counts (DHC), phenoloxidase (PO) activity, and prophenoloxidase (proPO) system-related genes were investigated in haemocytes of Litopenaeus vannamei that received saline, norepinephrine (NE), and NE co-treated with various adrenergic receptor (AR) antagonists both in vivo and in vitro. Results showed that semi-granular and granular cells of shrimp which received NE, NE + phentolamine (Phe), NE + prazosin (Pra), NE + propanolol (Pro) and NE + metoprolol (Met) significantly decreased, while the PO activity of the shrimp received NE + Phe in vivo was significant higher than all the other treatments. PO activities of haemocytes exposed to saline, Pra + NE, and Met + NE were significantly higher than those of haemocytes exposed to NE, Phe + NE, and Pro + NE in vitro. Similar phenomena in lipopolysaccharide- and β-1,3-glucan-binding protein (LGBP), proPO-I, proPO-II, serine proteinases (SP), and peroxinectin (PE) messenger (m)RNA expressions of haemocytes exposed to saline, NE, and NE co-treated with various AR antagonists were observed both in vivo and in vitro. No significant differences were observed for LGBP and proPO-II mRNA expressions between haemocytes treated with saline and Pra + NE, for proPO-I mRNA expression between haemocytes treated with saline and Met + NE; or for SP and PE mRNA expressions among haemocytes treated with saline, Pra + NE, and Met + NE. These results suggest that stress-induced NE may promote the migration of circulating granulocytes to the site of the injection and the existing proPO mRNA translation which had been stored in granulocytes. NE downregulated the LGBP, proPO-I, proPO-II, SP, and PE gene transcription by haemocytes via α1-, β1-, α1-, α1- and β1-, and α1- and β1-ARs, respectively, which subsequently decreased the PO activity by α1- and β1-ARs in haemocytes of L. vannamei.

Abstract
The survival rate, weight loss, immune parameters, resistance against Vibrio alginolyticus and white-spot syndrome virus (WSSV), and expressions of lipopolysaccharide- and ß-glucan-binding protein (LGBP), peroxinectin (PX), prophenoloxidase-activating enzyme (ppA), prophenoloxidase (proPO) I, proPO II, α2-macroglobulin (α2-M), integrin ß, heat shock protein 70 (HSP70), cytosolic manganese superoxide dismutase (cytMnSOD), mitochondrial manganese superoxide dismutase (mtMnSOD), and extracellular copper and zinc superoxide dismutase (ecCuZnSOD) were examined in the white shrimp Litopenaeus vannamei (8.18 ± 0.86 g body weight) which had been denied food (starved) for up to 14-28 days. Among shrimp which had been starved for 7, 14, 21, and 28 days, 100%, 90%, 71%, and 59% survived, and they lost 3.2%, 7.3%, 9.2%, and 10.4% of their body weight, respectively. Hyaline cells (HCs), granular cells (GCs, including semi-granular cells), the total haemocyte count (THC), phenoloxidase (PO) activity, respiratory bursts (RBs), and SOD activity significantly decreased in shrimp which had been starved for 1, 1, 1, 5, 14, and 3 days, respectively. The expression of integrin ß significantly decreased after 0.5-5 days of starvation, whereas the expressions of LGBP, PX, proPO I, proPO II, ppA, and α2-M increased after 0.5-1 days. Transcripts of all genes except ecCuZnSOD decreased to the lowest level after 5 days, and tended to background values after 7 and 14 days. Cumulative mortality rates of 7-day-starved shrimp challenged with V. alginolyticus and WSSV were significantly higher than those of challenged control-shrimp for 1-7 and 1-4 days, respectively. In another experiment, immune parameters of shrimp which had been starved for 7 and 14 days and then received normal feeding (at 5% of their body weight daily) were examined after 3, 6, and 12 h, and 1, 3, and 5 days. All immune parameters of 7-day-starved shrimp were able to return to their baseline values after 5 days of re-feeding except for GCs, whereas all parameters of 14-day-starved shrimp failed to return to the baseline values even with 5 days of re-feeding. It was concluded that shrimp starved for 14 days exhibited three stages of modulation of gene expression, together with reductions in immune parameters, and decreased resistance against pathogens.

Abstract
Crustacean aquaculture represents a major industry in tropical developing countries. As a result of high culture densities and increasing extension of aquaculture farms, the presence of diseases has also increased, inducing economic losses. Invertebrates, which lack adaptive immune systems, have developed defense systems that respond against antigens on the surface of potential pathogens. The defense mechanisms of crustaceans depend completely on the innate immune system that is activated when pathogen-associated molecular patterns are recognized by soluble or by cell surface host proteins, such as lectins, antimicrobial, clotting, and pattern recognition proteins, which, in turn, activate cellular or humoral effector mechanisms to destroy invading pathogens. This work is aimed at presenting the main characteristics of the crustacean proteins that participate in immune defense by specific recognition of carbohydrate containing molecules, i.e. glycans, glycolipids, glycoproteins, peptidoglycans, or lipopolysaccharides from Gram-negative and Gram-positive bacteria, viruses, or fungi. We review some basic aspects of crustacean effector defense processes, like agglutination, encapsulation, phagocytosis, clottable proteins, and bactericidal activity, induced by these carbohydrate-driven recognition patterns.

Abstract
The prophenoloxidase (ProPO) system is the origin of melanin production and is considered to be an innate defence mechanism in invertebrates. In different bivalve species, phenoloxidase (PO) is present in the haemolymph as an inactive form of ProPO. The present study focuses on the Pacific adult oyster, Crassostrea gigas, an economically important bivalve species along French coasts. The results indicate that many factors may inhibit the PO-like activity. These include: phenylthiourea (PTU), sodium diethylthiocarbamate (DETC), beta-mercaptoethanol and tropolone, which repressed the spontaneous PO activity. The activation of PO-like activity in C. gigas acellular fraction by lipopolysaccharide (LPS) involved participation of other factors, including at least one serine protease. PO was present as proPO in the acellular fraction of haemolymph and haemocytes of C. gigas and could be activated by an exogenous protease (trypsin-N-tosyl-l-phenylalanine chloromethyl ketone) when used at 1 gL(-1). Treatment of acellular fractions with other modulators/activators namely LPS (1 gL(-1)), zymosan (0.6 gL(-1)) or laminarin (0.6 gL(-1)) also increased PO-like activity but to a less important way. The study demonstrated the evidence of a true phenoloxidase activity in Pacific oyster, C. gigas (Thunberg). The activation of a proPO system by non-self molecules suggests the role played by PO in vivo in the internal defence mechanisms. Understanding the activation of the ProPO system could enable the evaluation of the health of oyster stocks.

Abstract
The hemocytes from the giant freshwater prawn Macrobrachium rosenbergii were examined for their ability to generate superoxide anion (O(2) (-)) in vitro upon exposure to various components derived from microbial cell wall components. Among the test molecules, laminarin (a polymer of beta-1, 3 glucans), mannan and LPS from five different bacterial species produced a differential response in terms of stimulated O(2) (-) production in prawn hemocytes, suggesting the ability of the hemocytes to differentiate non-self. This response was almost completely inhibited by superoxide dismutase (SOD) suggesting SOD-inhibitable O(2) (-) generation by prawn hemocytes. Phorbol 12-myristate 13-acetate (PMA) and Ca ionophore led to enhanced O(2) (-) generation by the hemocytes and this suggests the possible role of protein kinase C and Ca(2+) ions in such generation. Cytochemical analysis using nitroblue tetrazolium (NBT)-staining revealed the importance of granular hemocytes in O(2) (-) generation in these prawns. Inhibition of O(2) (-) generation by inhibitors of NADPH-oxidase and phenoloxidase pathways clearly reveal the involvement of two different pathways in non-self stimulated O(2) (-) generation by the prawn hemocytes. These findings demonstrate the importance of O(2) (-) generation and role of possible pathways in hemocyte mediated cellular immune response of a crustacean.

Molecular cloning and characterisation of prophenoloxidase cDNA from haemocytes of the giant freshwater prawn, Macrobrachium rosenbergii, and its transcription in relation with the moult stage. FISH & SHELLFISH IMMUNOLOGY 2006; 21:60-9.

Abstract
Expression of prophenoloxidase (proPO) cDNA was determined from haemocytes of the giant freshwater prawn Macrobrachium rosenbergii by a reverse-transcription polymerase chain reaction (RT-PCR) and rapid amplification of cDNA using oligonucleotide primers based on the proPO sequence of tiger shrimp Penaeus monodon, freshwater crayfish Pacifastacus leniusculus, green tiger shrimp Penaeus semisulcatus, kuruma shrimp Marsupenaeus japonicus, and white shrimp Litopenaeus vannamei. The proPO of M. rosenbergii was constitutively expressed. The 2,547-bp cDNA contained an open reading frame (ORF) of 2,013 bp, a 96-bp 5'-untranslated region, and a 438-bp 3'-untranslated region containing the poly A tail. The molecular mass of the deduced amino acid (aa) sequence (671 aa) was 76.7 kDa with an estimated pI of 7.05. It contained putative copper-binding sites, a complement-like motif (GCGWPRHM), a proteolytic activation site, and a conserved C-terminal region common to all known proPOs. However, no signal peptide sequence was detected in giant freshwater prawn proPO. Comparison of amino acid sequences showed that prawn proPO is similar to the proPO of penaeid, crayfish and lobster. Prawn proPO was only synthesised in haemocytes. The proPO transcript was significantly increased in the A stage and achieved the highest level in the B stage, and then declined sharply in the C stage and reached the lowest level in the D(2)/D(3) stage.

Abstract
Arthropod phenoloxidases catalyze the melanization and sclerotization of the new postmolt exoskeleton, and they function in the immune response. Hemocyanin, phylogenetically related to phenoloxidase, can function as a phenoloxidase under certain conditions. We investigated the relative contributions of hemocyte phenoloxidase and hemocyanin in the brachyuran crab Cancer magister, using the physiological ratio at which they occur in the hemolymph, and found that hemocyte phenoloxidase has higher activity. They both convert diphenols to o-quinones, but only the hemocyte phenoloxidase is able to catalyze the conversion of monophenols to diphenols. The quaternary structure of hemocyanin affects its reactivity as phenoloxidase. We suggest that prophenoloxidase is released from hemocytes and moves across epidermis into new exoskeleton during premolt and is activated in early postmolt. In addition to functional studies, we have determined the complete cDNA sequence of C. magister hemocyte prophenoloxidase and partial sequences from the branchiopods Artemia franciscana and Triops longicaudatus. We also sequenced C. magister cryptocyanin 2 and a hemocyanin from the amphipod Cyamus scammoni and used these and other members of the arthropod hemocyanin superfamily for phylogenetic analyses. The phylogenies presented here are consistent with the possibility that a common ancestral molecule had both phenoloxidase and reversible oxygen-binding capabilities.

Abstract
A high density lipoprotein-beta glucan binding protein (HDL-BGBP) is synthesized in the hepatopancreas of the white shrimp Litopenaeus vannamei and secreted to the hemolymph. Recently, we reported the HDL-BGBP full length cDNA sequence and found that the predicted polypeptide is larger than the mature protein and also, that it contains a long 5'- and 3'-UTRs that may be involved in transcript level regulation. To test whether starvation and feeding may play a role in regulating HDL-BGBP mRNA levels, two different stimuli were evaluated: starvation and composition of diets. After 24 h, the steady state HDL-BGBP mRNA levels of starved shrimp decreased, suggesting that synthesis of the lipoprotein is less required in the absence of food. When shrimp were fed with diets containing different concentrations of protein and lipids, changes in HDL-BGBP mRNA levels were also detected. Shrimp fed the lower concentration of protein and lipid feed accumulated higher levels of HDL-BGBP mRNA. These results indicate that feeding influences HDL-BGBP transcript levels in the hepatopancreas.

Abstract
The role of vertebrate histone proteins or histone derived peptides as innate immune effectors has only recently been appreciated. In this study, high levels of core histone proteins H2A, H2B, H3 and H4 were found in hemocytes from the Pacific white shrimp, Litopenaeus vannamei. The proteins were identified by in-gel digestion, mass spectrometry analysis, and homology searching. The L. vannamei histone proteins were found to be highly homologous to histones of other species. Based on this homology, histone H2A was cloned and its N-terminus was found to resemble the known antimicrobial histone peptides buforin I, parasin, and hipposin. Consequently, a 38 amino acid synthetic peptide identical to the N-terminus of shrimp H2A was synthesized and assayed, along with endogenous histones H2A, H2B, and H4, for growth inhibition against Micrococcus luteus. Histone H2A, purified to homogeneity, completely inhibited growth of the Gram-positive bacterium at 4.5 microm while a mixture of histones H2B and H4 was active at 3 microm. In addition, a fraction containing a fragment of histone H1 was also found to be active. The synthetic peptide similar to buforin was active at submicromolar concentrations. These data indicate, for the first time, that shrimp hemocyte histone proteins possess antimicrobial activity and represent a defense mechanism previously unreported in an invertebrate. Histones may be a component of innate immunity more widely conserved, and of earlier origin, than previously thought.

Abstract
cDNA encoding prophenoloxidase (proPO) of the white shrimp Litopenaeus vannamei was obtained from haemocytes by a reverse-transcription polymerase chain reaction (RT-PCR) and rapid amplification of cDNA using oligonucleotide primers based on the proPO sequence of tiger shrimp Penaeus monodon, freshwater crayfish Pacifastacus leniusculus, green tiger shrimp Penaeus semisulcatus (accession no.: AF521949) and kuruma shrimp Marsupenaeus japonicus (accession no.: AB0733223). proPO of L. vannamei was constitutively expressed. The 2471-bp cDNA contained an open reading frame (ORF) of 2058 bp, a 96-bp 5'-untranslated region, and a 317-bp 3'-untranslated region containing the poly A tail. The molecular mass of the deduced amino acid sequence (686 amino acids) was 78.1 kDa with an estimated pI of 6.02. It contained putative copper binding sites, a complement-like motif (GCGWPQHM), a proteolytic activation site, and a conserved C-terminal region common to all known proPOs. However, no signal peptide sequence was detected in white shrimp proPO. Comparison of amino acid sequences showed that white shrimp proPO is more closely related to the proPO of another penaeid than to that of a freshwater crayfish. White shrimp proPO mRNA was synthesized in haemocytes and not in the hepatopancreas or muscle. The activation responses of the proPO of the white shrimp to an exogenous protease (trypsin), a detergent (sodium dodecyl sulphate), and algal and microbial cell wall components (laminarin, sodium alginate, zymosan, and lipopolysaccharide), and its susceptibility to protease inhibitors in vitro resemble the proPO activation system of other crustaceans. These facts suggest that the proPO system in haemocytes of the white shrimp Litopenaeus vannamei serves an important function in non-self recognition and host immune reactions.

Abstract
A lipopolysaccharide- and beta-1,3-glucan binding protein (LGBP) cDNA was cloned from the haemocyte and hepatopancreas of white shrimp Litopenaeus vannamei using oligonucleotide primers and RT-PCR. Both 3'- and 5'-regions were isolated by rapid amplification of cDNA end RACE method. Analysis of nucleotide sequence revealed that the cDNA clone has an open reading frame of 1101 bp encoding a protein of 367 amino acids including a 17 amino acid signal peptide. The calculated molecular mass of the mature proteins (350 amino acids) is 39.92 kDa with an estimated pI of 4.37. Two putative integrin binding motifs (cell adhesion site), RGD (Arg-Gly-Asp) and a potential recognition motif for beta- (1-->3) linkage of polysaccharides were observed in the LGBP. Sequence comparison showed that LGBP deduced amino acid of L. vannamei has an overall similarity of 95%, 92% and 61% to that of blue shrimp Litopenaeus stylirostris LGBP, tiger shrimp Penaeus monodon BGBP and crayfish Pacifastacus leniusculus LGBP, respectively. Quantitative real-time RT-PCR analysis showed that LGBP transcript in haemocyte of L. vannamei increased in 3- and 6-h post Vibrio alginolyticus injection.

Abstract
An association between vitellogenesis and the immune system was suggested in crustaceans from studies on plasma lipoproteins. The present research studies the effect of an experimentally induced bacterial infection on vitellogenesis in females of the shrimp Penaeus indicus, as a model for penaeid species. Pre-vitellogenic and vitellogenic P. indicus females were experimentally infected with an extremely pathogenic bacterium, Vibrio penaeicida. The peak in mortality occurred earlier in pre-vitellogenic animals than in vitellogenic ones, although the final mortality level ( approximately 64-74%) 52h post-infection was nearly the same for the two groups. Twenty hours after infection, the total number of haemocytes was significantly reduced in vitellogenic females while there was no change in the pre-vitellogenic group. Protein synthesis in ovaries was not significantly affected by infection, at the two stages of ovarian development. No differences were found in mRNA levels of shrimp ovarian peritrophin protein (SOP), but preliminary results showed that mRNA expression of vitellin (VT) was reduced in a heavily infected vitellogenic female. The total amount of lipids in the haemolymph of vitellogenic females was almost twice higher than that of pre-vitellogenic ones. However, there was no change in the total content of lipids, lipid classes and fatty acid distribution in haemolymph or hepatopancreas following infection. Although vitellogenic and pre-vitellogenic females probably respond differently to a lethal bacterial infection, physiological differences may be concealed by the rapid onset of mortality.

Abstract
Shrimp BGBP was purified as a 100 kDa glycoprotein by affinity chromatography using immobilised heparin. BGBP bound simple carbohydrates, glycosaminoglycans like heparin sulphate and glycoproteins, but it was unable to agglutinate erythrocytes. Using an ELISA-based microplate assay, it was shown that simple carbohydrates such as n-glucose and D-mannose are competitive inhibitors of heparin sulphate binding to BGBP. Based on these properties BGBP is considered as a new type of heparin binding protein.

Abstract
Pattern recognition proteins such as lipopolysaccharide and beta-1,3-glucan binding protein (LGBP) play an important role in the innate immune response of crustaceans and insects. Random sequencing of cDNA clones from a hepatopancreas cDNA library of white spot virus (WSV)-infected shrimp provided a partial cDNA (PsEST-289) that showed similarity to the LGBP gene of crayfish and insects. Subsequently full-length cDNA was cloned by the 5'-RACE (rapid amplification of cDNA ends) technique and sequenced. The shrimp LGBP gene is 1,352 bases in length and is capable of encoding a polypeptide of 376 amino acids that showed significant similarity to homologous genes from crayfish, insects, earthworms, and sea urchins. Analysis of the shrimp LGBP deduced amino acid sequence identified conserved features of this gene family including a potential recognition motif for beta-(1-->3) linkage of polysaccharides and putative RGD cell adhesion sites. It is known that LGBP gene expression is upregulated in bacterial and fungal infection and that the binding of lipopolysaccharide and beta-1,3-glucan to LGBP activates the prophenoloxidase (proPO) cascade. The temporal expression of LGBP and proPO genes in healthy and WSV-challenged Penaeus stylirostris shrimp was measured by real-time quantitative reverse transcription-PCR, and we showed that LGBP gene expression in shrimp was upregulated as the WSV infection progressed. Interestingly, the proPO expression was upregulated initially after infection followed by a downregulation as the viral infection progressed. The downward trend in the expression of proPO coincided with the detection of WSV in the infected shrimp. Our data suggest that shrimp LGBP is an inducible acute-phase protein that may play a critical role in shrimp-WSV interaction and that the WSV infection regulates the activation and/or activity of the proPO cascade in a novel way.

Abstract
A beta-1,3-glucan binding protein (GBP) has been isolated from a shrimp hemocyte cDNA library. Its open reading frame consists of 1314 nucleotides with a polyadenylated sequence and a poly A tail. It encodes a polypeptide of 370 amino acids including a 17 amino acid-signal peptide. The mature protein has an estimated molecular mass of 39.5 kDa and a predicted pI of 5.5. Sequence comparison shows a high degree of similarity to invertebrate recognition proteins with glucanase-like domains for example, the lipopolysaccharide- and beta-1,3-glucan-binding protein (LGBP) from the freshwater crayfish, Pacifastacus leniusculus, coelomic cytolytic factor-1 from the earthworm, Eisenia foetida and the Gram negative bacteria binding protein from the mosquito, Anopheles gambiae as well as to sea urchin beta-1,3-glucanases and bacterial beta-1,3-glucanases or beta-1,3-, 1,4-glucanases. Northern blot analysis showed that the shrimp protein is constitutively expressed in hemocytes. Animals injected with curdlan or heat-killed bacterial cell of Vibrio harveyi, a shrimp pathogen, showed no significant change in the mRNA expression profile within 12h post-injection. After incubation of shrimp hemocyte lysate supernatant (HLS) with curdlan or zymosan, a protein with a molecular mass of 31 kDa was eluted from the incubated curdlan or zymosan, and, by immunoblotting, this 31-kDa band could be detected by an affinity-purified anti-crayfish LGBP antibody. In contrast, incubation of shrimp HLS with LPS showed no any reactive band detected on SDS-PAGE or by immunoblotting suggesting that the binding is specific for beta-1,3-glucan.

Abstract
The clottable protein (CP) was isolated from white shrimp, Penaeus vannamei plasma as a 400-kDa protein that splits to two identical 200-kDa subunits when it is reduced with 2-ME. However, using DTT as reducing agent, four main bands were observed; two of them (179 and 125 kDa) had the same N-terminus sequence of the intact CP, indicating that most fragmentation occurs in the carboxy-terminus. The proteinase activity of reduced CP was detected using azoalbumin as substrate. Proteinase activity was only detected in the reduced, but not alkylated protein. Trypsin and papain, as well as soybean trypsin inhibitor and E64, were included for comparison. Proteolytic activity of reduced CP was inhibited by E64, but not by STI, indicating that such activity corresponds to a cysteine type proteinase.

Abstract
A pilot program was undertaken in immune gene discovery in two sister species of litopenaeid shrimp, the Pacific white shrimp, Litopenaeus vannamei and the Atlantic white shrimp, L. setiferus. RNA from the hemocytes and hepatopancreas of single individuals from each species was recovered, 4 cDNA libraries (one from each tissue/species) were made by a PCR-based method and a total of approximately 2045 randomly selected clones were sequenced. A total of 268 expressed sequence tags (ESTs) were found that corresponded to 44 immune function genes. The most common immune-function ESTs (172) were antimicrobial peptides, which were restricted to the hemocyte libraries. Lectins were the largest group of immune-function ESTs found in the hepatopancreas. Analysis of these libraries indicates that EST approaches are effective for immune gene discovery in shrimp and that the diversity of these PCR-generated libraries would support full-scale EST collection.

Abstract
Pattern recognition proteins function in innate immune responses by binding to molecules on the surface of invading pathogens and initiating host defense reactions. We report the purification and molecular cloning of a cDNA for a 53-kDa beta1,3-glucan-recognition protein from the tobacco hornworm, Manduca sexta. This protein is constitutively expressed in fat body and secreted into hemolymph. The protein contains a region with sequence similarity to several glucanases, but it lacks glucanase activity. It binds to the surface of and agglutinates yeast, as well as gram-negative and gram-positive bacteria. Beta1,3-glucan-recognition protein in the presence of laminarin, a soluble glucan, stimulated activation of prophenoloxidase in plasma, whereas laminarin alone did not. These results suggest that beta1,3-glucan-recognition protein serves as a pattern recognition molecule for beta1,3-glucan on the surface of fungal cell walls. After binding to beta1,3-glucan, the protein may interact with a serine protease, leading to the activation of the prophenoloxidase cascade, a pathway in insects for defense against microbial infection.

Abstract
Beta-1,3-1,6-glucan, derived from bakers' yeast Saccharomyces cerevisiae, was used in the present study to investigate the extent to which glucan is able to protect spawners from white spot syndrome associated virus (WSSV), and whether this protection (if any) can be passed on to hatchlings via maternal transmission of immunity. Results showed that fewer spawners in the glucan-injected groups showed the clinical symptoms of red body coloration and white spots on the shell during the 15 days between eyestalk ablation and the end of repeated spawning. This suggests that the application of glucan might lead to a slight enhancement of disease resistance in spawners, although the differences were not statistically significant within the confidence limit chosen. Challenge results showed a significant increase in relative percent survival for larvae derived from groups of glucan-injected spawners compared to those derived from groups of untreated spawners. It therefore seems that a maternally transmitted disease resistance induced by glucan, protected the larvae against a WSSV infection. Glucan immersion was not only shown to be effective for nauplii derived from spawners that were not injected with glucan, it also provided additional, cumulative protection for nauplii which already had a maternally transmitted resistance to WSSV. This is the first documented demonstration of a maternal transmission of immunity in invertebrates.

Abstract
A cDNA encoding shrimp, Penaeus monodon, prophenoloxidase (proPO) was obtained by screening a hemocyte library by plaque hybridization using a proPO cDNA fragment from freshwater crayfish, Pacifastaceus leniusculus, as a probe. The 3,002 bp cDNA contains an open reading frame of 2,121 bp and a 881 bp 3'-untranslated region. The molecular mass of the deduced amino acid sequence (688 amino acids) is 78,700 Da with an estimated pI of 5.8. Two putative copper binding sites are present and they have a highly conserved sequence around these sites. No signal peptide was detected in the shrimp proPO, as has been previously shown to be the case for all arthropod proPOs cloned so far. The cleavage site of zymogen activation is likely to be between Arg 44 and Val 45. A tentative complement-like motif (GCGWPQHM) is also present. Shrimp proPO mRNA is synthesized in the hemocytes and not in the hepatopancreas. Comparison of amino acid sequences showed that shrimp proPO is more closely related to another crustacean proPO, namely crayfish, than to the insect proPOs.

Abstract
A high density lipoprotein (HDL) and beta-glucan binding protein (BGBP) have been found in the hemolymph of marine shrimp. These proteins are involved in the transport of lipid and the recognition of foreign matter, respectively. Similarities in the color of the proteins and the molecular mass were noted. For a detailed comparison, HDL and BGBP were purified from two shrimp species, Penaeus vannamei and Penaeus californiensis, and their biochemical characteristics determined. Both proteins from each of the shrimp species are monomeric with approximately the same molecular mass in sodium dodecyl sulfate-polyacrylamide gel electrophoresis (approximately 100-112 kDa) and contain carbohydrate and lipid. The amino acid composition is similar and there is a high degree of similarity in the N-terminus. Furthermore, they are recognized by antibodies prepared independently. These results reveal that BGBP and HDL in shrimp hemolymph are the same protein, suggesting that there is a close relationship between the ability to respond to foreign matter and the diet as a provider of essential nutrients.
