Abstract
The cold tolerance of Litopenaeus vannamei is important for breeding in specific areas. To explore the cold tolerance mechanism of L. vannamei, this study analyzed biochemical indicators, cell apoptosis, and metabolomic responses in cold-tolerant (Lv-T) and common (Lv-C) L. vannamei under low-temperature stress (18 °C and 10 °C). TUNEL analysis showed a significant increase in apoptosis of hepatopancreatic duct cells in L. vannamei under low-temperature stress. Biochemical analysis showed that Lv-T had significantly increased levels of superoxide dismutase (SOD) and triglycerides (TG), while alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH-L), and uric acid (UA) levels were significantly decreased compared to Lv-C (p < 0.05). Metabolomic analysis displayed significant increases in metabolites such as LysoPC (P-16:0), 11beta-Hydroxy-3,20-dioxopregn-4-en-21-oic acid, and Pirbuterol, while metabolites such as 4-Hydroxystachydrine, Oxolan-3-one, and 3-Methyldioxyindole were significantly decreased in Lv-T compared to Lv-C. The differentially regulated metabolites were mainly enriched in pathways such as Protein digestion and absorption, Central carbon metabolism in cancer and ABC transporters. Our study indicate that low temperature induces damage to the hepatopancreatic duct of shrimp, thereby affecting its metabolic function. The cold resistance mechanism of Lv-T L. vannamei may be due to the enhancement of antioxidant enzymes and lipid metabolism.

FISH & SHELLFISH IMMUNOLOGY 2024; 151:109689. [PMID: 38866349 DOI: 10.1016/j.fsi.2024.109689] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/22/2024] [Revised: 05/20/2024] [Accepted: 06/09/2024] [Indexed: 06/14/2024]
Abstract
Succinate dehydrogenase (SDH) is a crucial enzyme in the tricarboxylic acid cycle (TCA) and has established roles in immune function. However, the understanding of SDH in Penaeus vannamei, particularly its involvement in immune responses, is currently limited. Through affinity proteomics, a potential interaction between hemocyanin (HMC) and SDH in shrimp has been identified. The successful cloning of PvSDH in this study has revealed a high degree of evolutionary conservation. Additionally, it has been found that hemocyanin regulates SDH not only at the transcriptional and enzymatic levels but also through confirmed protein-protein interactions observed via Co-immunoprecipitation (CoIP) assay. Moreover, by combining PvHMC knockdown and Vibrio parahaemolyticus challenge, it was demonstrated that fumaric acid, a product of SDH, enhances the host's immune resistance to pathogen infection by modulating the expression of antimicrobial peptides. This research provides new insights into HMC as a crucial regulator of SDH, potentially impacting glycometabolism and the dynamics of immune responses.

Abstract
Hemocyanin, an oxygen-transport protein, is widely distributed in the hemolymph of marine arthropods and mollusks, playing an important role in their physiological processes. Recently, hemocyanin has been recognized as a multifunctional glycoprotein involved in the immunological responses of aquatic invertebrates. Consequently, the link between hemocyanin functions and their potential applications has garnered increased attention. This review offers an integrated overview of hemocyanin's structure, physicochemical characteristics, and bioactivities to further promote the utilization of hemocyanin derived from marine products. Specifically, we review its implication in two aspects of food and aquaculture industries: quality and health. Hemocyanin's inducible phenoloxidase activity is thought to be an inducer of melanosis in crustaceans. New anti-melanosis agents targeted to hemocyanin need to be explored. The red-color change observed in shrimp shells is related to hemocyanin, affecting consumer preferences. Hemocyanin's adaptive modification in response to the aquatic environment is available as a biomarker. Additionally, hemocyanin is endowed with bioactivities encompassing anti-microbial, antiviral, and therapeutic activities. Hemocyanin is also a novel allergen and its allergenic features remain incompletely characterized.

Abstract
Hemocyanin is the main respiratory protein of arthropods and is formed by hexameric and/or oligomeric subunits. Due to changes in the living environment and gene rearrangement, various hemocyanin subtypes and subunits evolved in crustaceans. This paper reviews the various hemocyanin subtypes and isoforms in shrimp and analyses published genomic data of sixteen hemocyanin family genes from Litopenaeus vannamei to explore the evolution of hemocyanin genes, subunits, and protein structure. Analysis of hemocyanin subtypes distribution and structure in various tissues was also performed and related to multiple and tissue-specific functions, i.e., immunological activity, immune signaling, phenoloxidase activity, modulation of microbiota homeostasis, and energy metabolism. The functional diversity of shrimp hemocyanin due to molecular polymorphism, transcriptional regulation, alternative splicing, degradation into functional peptides, interaction with other proteins or genes, and structural differences will also be highlighted for future research. Inferences would be drawn from other crustaceans to explain how evolution has changed the structure-function of hemocyanin and its implication for evolutionary research into the multifunctionality of hemocyanin and other related proteins in shrimp.

Abstract
Hemocyanin is a respiratory protein, it is also a multifunctional immune molecule that plays a vital role against pathogen invasion in shrimp. However, the regulation of hemocyanin gene expression in shrimp hemocytes and the mechanisms involved during pathogen infection remains unclear. Here, we used DNA pull-down followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) to identify the Yin Yang 1 transcription factor homolog in Penaeus vannamei (PvYY1) as a key factor that modulates transcription of the small subunit hemocyanin gene of P. vannamei (PvHMCs) in hemocytes during Vibrio parahaemolyticus AHPND (VPAHPND) infection. Bioinformatics analysis revealed that the core promoter region of PvHMCs contains two YY1 motifs. Mutational and oligoprecipitation analyses confirmed that PvYY1 could bind to the YY1 motifs in the PvHMCs core promoter region, while truncation of PvYY1 revealed that the N-terminal domain of PvYY1 is essential for the transactivation of PvHMCs core promoter. Besides, the REPO domain of PvYY1 could repress the activity of the PvHMCs core promoter. Overexpression of PvYY1 significantly activates the promoter activity of PvHMCs core promoter, while PvYY1 knockdown significantly decreases the expression level of PvHMCs in shrimp hemocytes and survival rate of shrimp upon infection with VPAHPND. Our present study provides new insights into the transcriptional regulation of PvHMCs by PvYY1 in shrimp hemocytes during bacteria (VPAHPND) infection.

Abstract
Besides dividing the organism's immune system into adaptive and innate immunity, it has long been thought that only adaptive immunity can establish immune memory. However, many studies have shown that innate immunity can also build immunological memory through epigenetic reprogramming and modifications to resist pathogens' reinfection, known as trained immunity. This paper reviews the role of mitochondrial metabolism and epigenetic modifications and describes the molecular foundation in the trained immunity of arthropods and mollusks. Mitochondrial metabolism and epigenetic modifications complement each other and play a key role in trained immunity.

Clodronate Liposome-Mediated Phagocytic Hemocyte Depletion Affects the Regeneration of the Cephalic Tentacle of the Invasive Snail, Pomacea canaliculata. BIOLOGY 2023; 12:992.

Abstract
After amputation, granular hemocytes infiltrate the blastema of regenerating cephalic tentacles of the freshwater snail Pomacea canaliculata. Here, the circulating phagocytic hemocytes were chemically depleted by injecting the snails with clodronate liposomes, and the effects on the cephalic tentacle regeneration onset and on Pc-Hemocyanin, Pc-transglutaminase (Pc-TG) and Pc-Allograft Inflammatory Factor-1 (Pc-AIF-1) gene expressions were investigated. Flow cytometry analysis demonstrated that clodronate liposomes targeted large circulating hemocytes, resulting in a transient decrease in their number. Corresponding with the phagocyte depletion, tentacle regeneration onset was halted, and it resumed at the expected pace when clodronate liposome effects were no longer visible. In addition to the regeneration progress, the expressions of Pc-Hemocyanin, Pc-TG, and Pc-AIF-1, which are markers of hemocyte-mediated functions like oxygen transport and immunity, clotting, and inflammation, were modified. After the injection of clodronate liposomes, a specific computer-assisted image analysis protocol still evidenced the presence of granular hemocytes in the tentacle blastema. This is consistent with reports indicating the large and agranular hemocyte population as the most represented among the professional phagocytes of P. canaliculata and with the hypothesis that different hemocyte morphologies could exert diverse biological functions, as it has been observed in other invertebrates.

Abstract
Hemocyanin, a copper-containing respiratory protein, is abundantly present in hemolymph of arthropods and mollusks and performs a variety of immunological functions. However, the regulatory mechanisms of hemocyanin gene transcription remain largely unclear. Our previous work showed that knockdown of the transcription factor CSL, a component of the Notch signaling pathway, downregulated the expression of Penaeus vannamei hemocyanin small subunit gene (PvHMCs), indicating the involvement of CSL in regulating the PvHMCs transcription. In this study, we identified a CSL binding motif ("GAATCCCAGA", +1675/+1684 bp) in the core promoter of PvHMCs (designated as HsP3). Dual luciferase reporter assay and electrophoretic mobility shift assay (EMSA) demonstrated that the CSL homolog in P. vannamei (PvCSL) could directly bind and activate the HsP3 promoter. Moreover, in vivo silencing of PvCSL significantly attenuated the mRNA and protein expression of PvHMCs. Finally, in response to Vibrio parahaemolyticus, Streptococcus iniae and white spot syndrome virus (WSSV) challenge, the transcript of PvCSL and PvHMCs showed a positive correlation, suggesting that PvCSL could also modulate the expression of PvHMCs upon pathogen stimulation. Taken together, our present finding is the first to demonstrate that PvCSL is a crucial factor in transcriptional control of PvHMCs.

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
Hemocyanin is an important non-specific innate immune defense molecule with phenoloxidase, antiviral, antibacterial, hemolytic, and antitumor activities. To better understand the mechanism of functional diversity, proteomics approach was applied to characterize hemocyanin (HMC) expression profiles from Litopenaeus vannamei. At first, hemocyanin was purified by Sephadex G-100 and DEAE-cellulose (DE-52) columns from shrimp serum, and 34 protein spots were identified as HMC on the 2-DE gels. Furthermore, we found that 9 HMC spots about 75 or 77 kDa were regulated by Streptococcus agalactiae and Vibrio parahaemolyticus infection at 6, 12, and 24 h. In addition, 6 different pathogen-binding HMC fractions, viz., HMC-Mix, HMC-Vp, HMC-Va, HMC-Vf, HMC-Ec, and HMC-Sa, showed different agglutinative and antibacterial activities. Moreover, lectin-blotting analysis showed significant differences in glycosylation level among HMC isomers and bacteria-binding HMC fractions. Particularly, the agglutinative activities of the HMC fractions were almost completely abolished when HMC was deglycosylated by O-glycosidase, which suggest that O-linked sugar chains of HMC played important roles in the innate immune recognition. Our findings demonstrated for the first time that L. vannamei HMC had molecular diversity in protein level, which is closely associated with its ability to recognize diverse pathogens, whereas glycan modification probably contributed to HMC’s diversity and multiple immune activities.

Abstract
In contrast to the external shells in bivalves and gastropods, most cephalopods are missing this external protection. The cuttlefish, belonging to class cephalopod, has an internal biomineralized structure made of mainly calcium carbonate for controlling buoyancy. However, the macromolecules, especially proteins that control cuttlebone mineral formation, are not sufficiently understood, limiting our understanding of the evolution of this internal shell. In this study, we extracted proteins from the cuttlebone of pharaoh cuttlefish Sepia pharaonis and performed liquid chromatography-tandem mass spectrometry to identify the shell matrix proteins (SMPs). In total, 41 SMPs were identified. Among them, hemocyanin, an oxygen-carrying protein, was the most abundant SMP. By comparison with SMPs of other marine biominerals, hemocyanin, apolipophorin, soul domain proteins, transferrin, FL-rich, and enolase were found to be unique to the cuttlebone. In contrast, typical SMPs of external shells such as carbonic anhydrase complement control protein, fibronectin type III, and G/A-rich proteins were lacking from the cuttlebone. Furthermore, the cluster analysis of biomineral SMPs suggests that the SMP repertoire of the cuttlebone does not resemble that of other species with external shells. Taken together, this study implies a potential relationship of the cuttlefish internal shell with other internal biominerals, which highlights a unique shell evolutionary pathway in invertebrates.

Abstract
Prophenoloxidase (proPO)-activating system is a critical innate immune defense in invertebrates. However, the mechanisms involved in regulating the phenoloxidase (PO) activity in shrimp hemolymph remain ill-defined. Our previous studies showed that Penaeus vannamei hemocyanin (HMC) and α2-macroglobulin (α2M), two key regulators of proPO-activating system in plasma, might interact with each other, indicating that this interaction could be implicated in controlling PO activity. Herein, we further confirmed that HMC specifically bind to α2M using Pull down and Far-Western blot analyses. Further studies demonstrated that HMC could directly interact with the receptor binding domain of α2M. In addition, HMC and α2M followed similar expression pattern upon Vibrio parahaemolyticus infection, suggesting the interaction of HMC and α2M might have a role in immune response. Finally, we found that α2M, as a broad-spectrum proteinase inhibitor, suppressed the serum PO activity in vitro, while hemocyanin could partially restore this inhibitory effect. In sum, the present data indicate that HMC interacts with α2M and therefore modulates the PO activity. This finding contributes to better understanding of stable state maintenance of PO activity in shrimp.

Abstract
Acute hepatopancreatic necrosis disease (AHPND) is a major debilitating disease that causes massive shrimp death resulting in substantial economic losses in shrimp aquaculture. The Pir toxin proteins secreted by a unique strain of Vibrio parahaemolyticus play an essential role in the pathogenesis of AHPND. At present, most studies on the effects of Pir toxin proteins in shrimp focus on digestive tissues or organs such as hepatopancreas, stomach, etc., with none on the immune organs. In the present study, two recombinant Pir toxin proteins (rPirA and rPirB) of V. parahaemolyticus were expressed with rPirB shown to enter shrimp hemocytes. Employing pull-down and LC-MS/MS analysis, GST-rPirB was found to interact with 13 proteins in hemocytes, including histone H3 and histone H4 and among which histone H4 had the highest protein score. Further analysis using GST pull-down and Far-Western blot analysis revealed that rPirB could interact with histone H4. In addition, using the purified nucleosome protein from Drosophila S2 cells, it was found that PirB protein could specifically bind to histones. When flow cytometry was applied, it was observed that the interaction between PirB and histones in shrimp hemocytes induces apoptosis, which results in the dephosphorylation of Serine 10 in histone H3. Collectively, the current study shows that in addition to its effect on the digestive tract of shrimp, the PirB toxin protein interacts with histones to affect the phosphorylation of histone H3-S10, thereby inducing apoptosis.

J Proteomics 2020; 232:104074. [PMID: 33309928 DOI: 10.1016/j.jprot.2020.104074] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2020] [Revised: 11/04/2020] [Accepted: 12/06/2020] [Indexed: 01/06/2023]
Abstract
Notch signaling pathway is a highly evolutionary conserved signaling pathway, which modulates many biological processes such as cell differentiation, tissue development and immune response. Our previous study revealed that Litopenaeus vannamei Notch (LvNotch) was involved in immune response by regulating reactive oxygen species (ROS) production in hemocytes. However, the immune regulatory networks mediated by LvNotch remain unclear in shrimp. In this study, 21 proteins that potentially interact with LvNotch were identified by GST pull-down and liquid chromatography tandem mass spectrometry (LC-MS/MS) analyses. Among these proteins, COP9 signalosome complex subunit 1 (CSN1) was chosen for further studies due to its putative role in immune response. The interaction between LvNotch and LvCSN1 was confirmed by Far-Western blot and GST pull-down analyses. In vivo knockdown of LvNotch resulted in an increase in LvCSN1 expression in hemocytes, which suggest that the COP9 signalosome complex might be negatively regulated by LvNotch. In addition, in vivo silencing of LvNotch upregulated the expression of LvDorsal, LvTNFSF and LvCrustin2 (NF-κB pathway related-genes), while their expression decreased after LvCSN1 depletion. Collectively, the current results indicate that LvNotch negatively regulates the NF-κB pathway by modulating LvCSN1 in shrimp. SIGNIFICANCE: Although the Notch signaling pathway has been implicated in the regulation of immune response in vertebrates and invertebrates, the functions and immune-related interacting networks of Notch in shrimp immune response remain unknown. In this study, twenty-one proteins including COP9 signalosome complex subunit 1 (CSN1) were identified as potential interacting partners of LvNotch. Further analysis revealed that LvNotch negatively regulates the NF-κB pathway by binding to CSN1 and modulating its expression. These findings for the first time suggest that the Notch signaling pathway has cross-talk with the NF-κB pathway in shrimp as part of the immune response.

Abstract
Singapore grouper iridovirus (SGIV) is a large double-stranded DNA virus that is a major threat to grouper aquaculture. The pathogenesis of SGIV is not well understood so far. Previous studies have revealed that ICP18, an immediate early protein encoded by SGIV ORF086R gene, promotes viral replication by regulating cell proliferation and virus assembly. In the present study, the potential functions of ICP18 were further explored by probing into its interactors using a proximity-dependent BioID method. Since our in-house grouper embryonic cells (a natural host cell of SGIV) could not be efficiently transfected with the plasmid DNA, and the grouper genome data for mass spectrometry-based protein identification is not currently available, we chosen a non-permissive cell (HEK293 T) as a substitute for this study. A total of 112 cellular proteins that potentially bind to ICP18 were identified by mass spectrometry analysis. Homology analysis showed that among these identified proteins, 110 candidate ICP18-interactors had homologous proteins in zebrafish (a host of SGIV), and shared high sequence identity. Further analysis revealed that the identified ICP18-interacting proteins modulate various cellular processes such as cell cycle and cell adhesion. In addition, the interaction between ICP18 and its candidate interactor, i.e., cyclin-dependent kinase1 (CDK1), was confirmed using Co-immunoprecipitation (Co-IP) and Pull-down assays. Collectively, our present data provides additional insight into the biological functions of ICP18 during viral infection, which could help in further unraveling the pathogenesis of SGIV.

Abstract
Hemocyanin is a respiratory protein that possesses multiple physiological and immunological functions in shrimp. However, the transcriptional regulation of the hemocyanin gene is still poorly understood. Here, the nuclear receptor E75 of Litopenaeus vannamei (LvE75) was identified as one of the transcriptional regulators that modulates the transcription of the small molecular weight hemocyanin gene of L. vannamei (LvHMCs) by inhibiting its core promoter activity in a Dual-luciferase assay. In silico analysis revealed that the core promoter (designated HsP3), which is located at +1517/+1849 bp of LvHMCs contained a putative E75 binding motif ("ACGGAAT", spanning +1812/+1818 bp). Further, LvE75 was shown to inhibit the core promoter activity by direct binding. Importantly, in vivo silencing of LvE75 resulted in a significant upregulation in the mRNA and protein expression of LvHMCs gene. Taken together, our present results provide direct evidence that LvE75 is a transcriptional suppressor of the LvHMCs gene expression.

Abstract
The copper-containing hemocyanins are proteins responsible for the binding, transportation and storage of dioxygen within the blood (hemolymph) of many invertebrates. Several additional functions have been attributed to both arthropod and molluscan hemocyanins, including (but not limited to) enzymatic activity (namely phenoloxidase), hormone transport, homeostasis (ecdysis) and hemostasis (clot formation). An important secondary function of hemocyanin involves aspects of innate immunity-such as acting as a precursor of broad-spectrum antimicrobial peptides and microbial/viral agglutination. In this chapter, we present the reader with an up-to-date synthesis of the known functions of hemocyanins and the structural features that facilitate such activities.

Abstract
Lipoproteins mediate the transport of apolar lipids in the hydrophilic environment of physiological fluids such as the vertebrate blood and the arthropod hemolymph. In this overview, we will focus on the hemolymph lipoproteins in Crustacea that have received most attention during the last years: the high density lipoprotein/β-glucan binding proteins (HDL-BGBPs), the vitellogenins (VGs), the clotting proteins (CPs) and the more recently discovered large discoidal lipoproteins (dLPs). VGs are female specific lipoproteins which supply both proteins and lipids as storage material for the oocyte for later use by the developing embryo. Unusual within the invertebrates, the crustacean yolk proteins-formerly designated VGs-are more related to the ApoB type lipoproteins of vertebrates and are now termed apolipocrustaceins. The CPs on the other hand, which are present in both sexes, are related to the (sex specific) VGs of insects and vertebrates. CPs serve in hemostasis and wound closure but also as storage proteins in the oocyte. The HDL-BGBPs are the main lipid transporters, but are also involved in immune defense. Most crustacean lipoproteins belong to the family of the large lipid transfer proteins (LLTPs) such as the intracellular microsomal triglyceride transfer protein, the VGs, CPs and the dLPs. In contrast, the HDL-BGBPs do not belong to the LLTPs and their relationship with other lipoproteins is unknown. However, they originate from a common precursor with the dLPs, whose functions are as yet unknown. The majority of lipoprotein studies have focused on decapod crustaceans, especially shrimps, due to their economic importance. However, we will present evidence that the HDL-BGBPs are restricted to the decapod crustaceans which raises the question as to the main lipid transporting proteins of the other crustacean groups. The diversity of crustaceans lipoproteins thus appears to be more complex than reflected by the present state of knowledge.

Abstract
Proteomic analyses techniques are considered strong tools for identifying and quantifying the protein contents in different organisms, organs and secretions. In fish biotechnology, the proteomic analyses have been used for wide range of applications such as identification of immune related proteins during infections and stresses. The proteomic approach has a significant role in understanding pathogen surviving strategies, host defence responses and subsequently, the fish pathogen interactions. Proteomic analyses were employed to highlight the virulence related proteins secreted by the pathogens to invade the fish host's defence barriers and to monitor the kinetics of protein contents of different fish organs in response to infections. The immune related proteins of fish and the virulence related proteins of pathogens are up or down regulated according to their functions in defence or pathogenesis. Therefore, the proteomic analyses are useful in understanding the virulence mechanisms of microorganisms and the fish pathogen interactions thereby supporting the development of new effective therapies. In this review, we focus and summarise the recent proteomic profiling studies exploring pathogen virulence activities and fish immune responses to stressors and infections.
