Int J Biol Macromol 2024; 261:129747. [PMID: 38281536 DOI: 10.1016/j.ijbiomac.2024.129747] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2023] [Revised: 01/23/2024] [Accepted: 01/23/2024] [Indexed: 01/30/2024]
Abstract
Serpins are a protein superfamily of serine protease inhibitors. One of their functions is to participate in immune responses by inhibiting the activation of prophenoloxidase. To elucidate the immune role of serpin in Macrobrachium nipponense, a serpin gene (Mnserpin) was cloned from M. nipponense in this study. Mnserpin protein has an N-terminal signal peptide and a serpin domain that contains a hinge region, a signature sequence of serpin and a P1(arginine)-P1' scissile bond, and evolutionally closely related to the crustacean serpins. Mnserpin highly expressed in the hepatopancreas and gill. Mnserpin expression increased first and then decreased after Vibrio parahaemolyticus and Aeromonas hydrophila infection, and was knocked down by dsMnserpin injection with a maximum knockdown efficiency of 92 %. Mnserpin knockdown increased the expression of the clip domain serine protease and prophenoloxidase genes and phenoloxidase activity of M. nipponense as well as its mortality rate after V. parahaemolyticus and A. hydrophila infection. The recombinant Mnserpin (rMnserpin) showed bacteria-binding and bacteriostatic activity in vitro. Moreover, rMnserpin injection decreased the bacterial number and the mortality rate of M. nipponense post V. parahaemolyticus and A. hydrophila infection. These results suggested that Mnserpin plays a major role in the innate immune response of M. nipponense.

JOURNAL OF FISH DISEASES 2024:e13935.

Abstract
Acute Hepatopancreatic Necrosis Disease (AHPND) represents a significant challenge in the field of shrimp aquaculture. This disease is primarily caused by Vibrio parahaemolyticus strains harbouring the pVA1 plasmid encoding the PirAvp and PirBvp toxins. To combat this epidemic and mitigate its devastating consequences, it is crucial to identify and characterize the receptors responsible for the binding of these pathogenic toxins. Our studied discovered that Penaeus vannamei's Serine protease inhibitor 3 (PvSerpin3) derived from shrimp hepatopancreatic tissues could bind to recombinant PirAvp , confirming its role as a novel PirAvp -binding protein (PA BP). Through comprehensive computational methods, we revealed two truncated PirAvp -binding proteins derived from PvSerpin3 called Serpin3(13) and Serpin3(22), which had higher affinity to PirAvp than the full-length PvSerpin3. The PA BP genes were amplified from a cDNA library that was reversed from total RNA extracted from shrimp, cloned and expressed in Escherichia coli. Three PA BP inclusion bodies were refolded to obtain the soluble form, and the recovery efficacy was found to be 100% for Serpin3 and Serpin3(13), while Serpin3(22) had a recovery efficacy of roundly 50%. Co-Immunoprecipitation (co-IP) and dot blot assays substantiated the interaction of these recombinant PA BPs with both recombinant PirAvp and VPAHPND (XN89)-producing natural toxins.

Abstract
Parasitoids introduce various virulence factors when parasitism occurs, and some taxa generate teratocytes to manipulate the host immune system and metabolic homeostasis for the survival and development of their progeny. Host-parasitoid interactions are extremely diverse and complex, yet the evolutionary dynamics are still poorly understood. A category of serpin genes, named CvT-serpins, was discovered to be specifically expressed and secreted by the teratocytes of Cotesia vestalis, an endoparasitoid of the diamondback moth Plutella xylostella. Genomic and phylogenetic analysis indicated that the C. vestalis serpin genes are duplicated and most of them are clustered into 1 monophyletic clade. Intense positive selection was detected at the residues around the P1-P1' cleavage sites of the Cv-serpin reactive center loop domain. Functional analyses revealed that, in addition to the conserved function of melanization inhibition (CvT-serpins 1, 16, 18, and 21), CvT-serpins exhibited novel functions, i.e. bacteriostasis (CvT-serpins 3 and 5) and nutrient metabolism regulation (CvT-serpins 8 and 10). When the host-parasitoid system is challenged with foreign bacteria, CvT-serpins act as an immune regulator to reprogram the host immune system through sustained inhibition of host melanization while simultaneously functioning as immune effectors to compensate for this suppression. In addition, we provided evidence that CvT-serpin8 and 10 participate in the regulation of host trehalose and lipid levels by affecting genes involved in these metabolic pathways. These findings illustrate an exquisite tactic by which parasitoids win out in the parasite-host evolutionary arms race by manipulating host immune and nutrition homeostasis via adaptive gene evolution and neofunctionalization.

Abstract
Background Chronic postsurgical pain (CPSP) in children remains an important problem with no effective preventive or therapeutic strategies. Recently, genomic underpinnings explaining additional interindividual risk beyond psychological factors have been proposed. Aims We present a comprehensive review of current preclinical and clinical evidence for genetic and epigenetic mechanisms relevant to pediatric CPSP. Methods Narrative review. Results Animal models are relevant to translational research for unraveling genomic mechanisms. For example, Cacng2, p2rx7, and bdnf mutant mice show altered mechanical hypersensitivity to injury, and variants of the same genes have been associated with CPSP susceptibility in humans; similarly, differential DNA methylation (H1SP) and miRNAs (miR-96/7a) have shown translational implications. Animal studies also suggest that crosstalk between neurons and immune cells may be involved in nociceptive priming observed in neonates. In children, differential DNA methylation in regulatory genomic regions enriching GABAergic, dopaminergic, and immune pathways, as well as polygenic risk scores for enhanced prediction of CPSP, have been described. Genome-wide studies in pediatric CPSP are scarce, but pathways identified by adult gene association studies point to potential common mechanisms. Conclusions Bench-to-bedside genomics research in pediatric CPSP is currently limited. Reverse translational approaches, use of other -omics, and inclusion of pediatric/CPSP endophenotypes in large-scale biobanks may be potential solutions. Time of developmental vulnerability and longitudinal genomic changes after surgery warrant further investigation. Emergence of promising precision pain management strategies based on gene editing and epigenetic programing emphasize need for further research in pediatric CPSP-related genomics.

Abstract
Acute hepatopancreatic necrosis disease (AHPND) is a recently emerged disease in aqua cultured shrimp that is caused by virulent strains of Vibrio parahaemolyticus (VP). Our previous study used transcriptomics to identify key pathogenic factors in the stomach of AHPND-infected shrimp (Litopenaeus vannamei), and here we used a different subset of the same data to construct a gene-to-gene expression correlation network to identify immune-responsive genes. LvSerpin7 was found to have the highest number of correlations after infection, and it also showed a significant increase in mRNA expression. LvSerpin7 is expressed in all tissues but its expression levels are highest in hemocytes. After successfully silencing LvSerpin7 transcript prior to AHPND challenge, mortality was significantly increased relative to the controls and reached 100% within 36 h post infection. Compared to the controls, the phenoloxidase (PO) activity also increased in both hemolymph and stomach. Recombinant LvSerpin7 inhibited shrimp PO activity in vitro, and we also found that rLvSerpin7 inhibited the growth of AHPND-causing bacteria. These results suggest that LvSerpin7 might reduce the toxic effects that result from unregulated activation of the PO defense system by AHPND-causing bacteria.

Abstract
Endocrine-disrupting chemicals (EDCs), xenobiotics that interfere with endogenous hormone function, have been studied for their impacts in aquatic environments. However, there is limited information about the potentially hazardous impact of bisphenol A (BPA) and di-(2-ethylhexyl) phthalate (DEHP) on the marine environment. The aim of this study was to investigate the effects of BPA and DEHP on the immune response of the intertidal mud crab, Macrophthalmus japonicus. In order to examine immunological responses involving the prophenoloxidase (proPO) system, mRNA transcript and activity levels of six immune-related genes, including lipopolysaccharide and β-1,3-glucan-binding protein (LGBP), proPO, phenoloxidase (PO), peroxinectin (PE), serine protease inhibitor (Serpin), and trypsin (Tryp), were assessed in M. japonicus hepatopancreas and gills exposed to BPA or DEHP. Expression of immune genes generally decreased in M. japonicus hepatopancreas and gills exposed to all concentrations of BPA by days 4 and 7. However, at day 1, expression of Serpin and Tryp genes was significantly increased in M. japonicus hepatopancreas and gills exposed to BPA. For DEHP exposure, all genes, with the exception of Serpin, were significantly downregulated in M. japonicus gills. In the hepatopancreas, gene expression of PO, proPO, and LGBP increased at day 1, and then decreased by day 7, while mRNA expression of Serpin and Tryp exhibited up-regulation over all exposure periods. In addition, PE gene expression was upregulated in hepatopancreas at day 7 in a dose-dependent manner. Taken together, these results indicated that the crab immune responses were perturbed by exposure to BPA, and, in particular, DEHP.

Abstract
Serpins are a family of serine protease inhibitors that are involved in numerous physiological processes and are known to regulate innate immunity pathways. To advance our understanding of their role in P. camtschaticus, a commercially significant species, we cloned and characterized a serpin from this species, designated serpin PC, that has anticoagulant and anticomplement effects on human blood. We found that serpin PC is a secreted protein with a typical serpin-like primary structure that is similar to other known crustacean serpins. Recombinant serpin PC was found to have inhibitory activity against R/K-specific bovine cationic trypsin. The reaction proceeds through the formation of a stable covalent complex of peptidase with P1 residue R383 of serpin PC. This interaction is characterized by a relatively high overall inhibition constant kass=(2.3 ± 0.7) × 106 M-1s-1 and an SI of 4.7 ± 0.8. Protein localization by western blotting showed that serpin PC is present in the muscles and, to a lesser extent, the heart, whereas it is transcribed predominantly in hemocytes and the heart. Through peptidase activity profiling of hemocytes and plasma, we found that serpin PC inhibits at least two R/K-specific activities and showed that it inhibits phenoloxidase (PO) activity induction in hemocytes.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2018; 80:81-93. [PMID: 28501515 DOI: 10.1016/j.dci.2017.05.009] [Citation(s) in RCA: 165] [Impact Index Per Article: 27.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/29/2017] [Revised: 05/10/2017] [Accepted: 05/10/2017] [Indexed: 06/07/2023]
Abstract
Diseases have caused tremendous economic losses and become the major problem threatening the sustainable development of shrimp aquaculture. The knowledge of host defense mechanisms against invading pathogens is essential for the implementation of efficient strategies to prevent disease outbreaks. Like other invertebrates, shrimp rely on the innate immune system to defend themselves against a range of microbes by recognizing and destroying them through cellular and humoral immune responses. Detection of microbial pathogens triggers the signal transduction pathways including the NF-κB signaling, Toll and Imd pathways, resulting in the activation of genes involved in host defense responses. In this review, we update the discovery of components of the Toll and Imd pathways in shrimp and their participation in the regulation of shrimp antimicrobial peptide (AMP) synthesis. We also focus on a recent progress on the two most powerful and the best-studied shrimp humoral responses: AMPs and melanization. Shrimp AMPs are mainly cationic peptides with sequence diversity which endues them the broad range of activities against microorganisms. Melanization, regulated by the prophenoloxidase activating cascade, also plays a crucial role in killing and sequestration of invading pathogens. The progress and emerging research on mechanisms and functional characterization of components of these two indispensable humoral responses in shrimp immunity are summarized and discussed. Interestingly, the pattern recognition protein (PRP) crosstalk is evidenced between the proPO activating cascade and the AMP synthesis pathways in shrimp, which enables the innate immune system to build up efficient immune responses.

Liu Y, Hou F, Liu X. Characterization and expression analysis of serpinB3, the first clade B serine protease inhibitor in Pacific white shrimp, Litopenaeus vannamei. DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2017; 72:103-111. [PMID: 28238878 DOI: 10.1016/j.dci.2017.02.019] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/06/2017] [Revised: 02/21/2017] [Accepted: 02/22/2017] [Indexed: 06/06/2023]
Abstract
Currently, about nine serpin clades (A-I) were preferentially observed in higher animals and clustered on the basis of function. Of these, eight clades contain extracellular proteins, while clade B contains predominantly intracellular proteins. In the present study, the first clade B serpin (named LvserpinB3) was identified from the Pacific white shrimp Litopenaeus vannamei. LvserpinB3 encoded a 412-amino acid protein with a 19-amino acid signal peptide and a serpin domain. Moreover, a transmembrane helix (TMHs) was predicted to be located on the N-terminal of LvserpinB3. Alignment with the cDNA sequence indicated that the genomic LvserpinB3 gene contains 2 exons and 1 intron. The P1-P1' scissile bond of the core feature reactive center loop (RCL) represented for Arginine-Isoleucine (RI), which was in accordance with PmserpinB3, Msserpin-4, -5 and -7. The highest mRNA expression level of LvserpinB3 was detected in hepatopancreas. A significant decrease of LvserpinB3 was detected in hepatopancreas at 6 h post Vibrio anguillarum injection, and later on, the expression of LvserpinB3 was remarkably elevated at 24 h post bacterial challenge. Suppression of LvserpinB3 in vivo by double-stranded RNA (dsRNA) mediated RNA interference (RNAi) led to a significant increase in the transcripts of LvSP1 (Serine protease 1), LvPPAE2 (Prophenoloxidase-activating Enzyme 2) and cumulative mortality. Furthermore, rLvserpinB3 protein was expressed and purified in vitro for the prophenoloxidase inhibition assay. The rLvserpinB3 protein can strongly impede the extent of proPO cascade. All above imply that LvserpinB3 might be an inhibitor for prophenoloxidase-activating system.

Identification and functional characterizations of serpin8, a potential prophenoloxidase-activating protease inhibitor in Pacific white shrimp, Litopenaeus vannamei. FISH & SHELLFISH IMMUNOLOGY 2017; 60:492-501. [PMID: 27836723 DOI: 10.1016/j.fsi.2016.11.024] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/02/2016] [Revised: 11/03/2016] [Accepted: 11/07/2016] [Indexed: 06/06/2023]
Abstract
Serpins have been characterized from varieties of organisms by their inhibitory roles on serine or cysteine proteases. However, research for the functional study of serpins in crustacean is relatively small. To fully clarify the immune characterizations of serpin, a novel serpin (named Lvserpin8) encoding 414 amino acids with a 19-amino acid signal peptide and a serpin domain was identified from the Pacific white shrimp Litopenaeus vannamei. Sequence analysis indicated that the genomic Lvserpin8 gene contains 5 exons and 4 introns. The P1 residues of the predicted scissile bond in the reactive center loop (RCL) region represented for Lysine (Lys), which is in accordance with Pmserpin8, Dmserpin27A, Ofserpin3, Bmserpin3 and Msserpin3. Quantitative results showed that high mRNA expression of Lvserpin8 was detected in hepatopancreas and testis. Notably, a significant increase of Lvserpin8 was appeared post injection of Vibrio anguillarum, and Micrococcus lysodeikticus. Moreover, Lvserpin8 was knocked down in vivo by double-stranded RNA (dsRNA) mediated RNA interference (RNAi). Suppression of Lvserpin8 led to a significant increase in the transcripts of LvPPAE2 (Prophenoloxidase-activating Enzyme 2) and cumulative mortality. What's more, recombinant Lvserpin8 protein (rLvserpin8) displayed inhibition roles on trypsin activity, and prophenoloxidase activation. Taken together, the results implied that Lvserpin8 may be involved in shrimp innate immunity via the inhibition of prophenoloxidase-activating proteases.

Abstract
Accumulation of nitrite in water is highly toxic to aquatic animals. To understand immune responses in shrimp under such environmental stress, a digital gene expression (DGE) technology was applied to detect the gene expression profile of the Litopenaeus vannamei hemocytes in response to nitrite for 48 h. A total of 1922 differently expressed unigenes were generated. Of these transcripts, 1269 and 653 genes were up- or down-regulated respectively. Functional categorization and pathways of the differentially expressed genes revealed that immune defense, xenobiotics biodegradation and metabolism, amino acid and nucleobase metabolic process, apoptosis were the differentially regulated processes occurring during nitrite stress. We selected 19 differential expression transcripts (DETs) to validate the sequencing results by real time quantitative PCR (qPCR). The Pearson's correlation coefficient (R) of the 19 DETs was 0.843, which confirmed the consistency and accuracy between these two approaches. Subsequently, we screened 10 genes to examine the changes in the time course of gene expression in more detail. The results indicated that expressions of ATP-binding cassette transporter (ABC transporter), caspase10, QM protein, C type lectin 4 (CTL4), protein disulfide isomerase (PDI), serine protease inhibitor 8 (SPI8), transglutaminase (TGase), chitinase1, inhibitors of apoptosis proteins (IAP) and cytochrome P450 enzyme (CYP450) were induced to participate in the anti-stress defense against nitrite. These results will provide a reference for follow-up study of molecular toxicology and valuable gene information for better understanding of immune response in L. vannamei under environmental stress.

FISH & SHELLFISH IMMUNOLOGY 2016; 48:128-135. [PMID: 26432049 DOI: 10.1016/j.fsi.2015.09.039] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/18/2015] [Revised: 09/16/2015] [Accepted: 09/25/2015] [Indexed: 06/05/2023]
Abstract
Serine protease inhibitor, represented by serpin, plays an important inhibitory role on proteases involved in the immune responses. To clarify the immune characterizations of serpin, a novel serpin (Lvserpin3) encoding for 410 amino acids with a 23-amino acid signal peptide and a serpin domain was identified from the Pacific white shrimp Litopenaeus vannamei. Lvserpin3 expressed strongest in hepatopancreas, and was significantly up-regulated in the early stage upon Vibrio anguillarum, Micrococcus lysodeikticus or White Spot Syndrome Virus (WSSV) infection. Suppression of Lvserpin3 by dsRNA led to a significant increase in the transcripts of LvPPAF, LvproPO and phenoloxidase (PO) activity, and also led to the high cumulative mortality. The recombinant Lvserpin3 protein (rLvserpin3) inhibited the proteases secreted by M. lysodeikticus and Bacillus subtilis, and further exhibited inhibitory role on the growth of B. subtilis and M. lysodeikticu. Moreover, rLvserpin3 was found to be able to block the activation of prophenoloxidase system. Taken together, the results imply that Lvserpin3 may be involved in shrimp innate immunity via the inhibition of bacterial proteases and proteases involved in prophenoloxidase system.

A shrimp pacifastin light chain-like inhibitor: molecular identification and role in the control of the prophenoloxidase system. DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2016; 54:32-45. [PMID: 26271600 DOI: 10.1016/j.dci.2015.08.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/26/2015] [Revised: 08/05/2015] [Accepted: 08/06/2015] [Indexed: 06/04/2023]
Abstract
Pacifastin is a recently classified family of serine proteinase inhibitors that play essential roles in various biological processes, including in the regulation of the melanization cascade. Here, a novel pacifastin-related gene, termed PmPacifastin-like, was identified from a reverse suppression subtractive hybridization (SSH) cDNA library created from hemocytes of the prophenoloxidase PmproPO1/2 co-silenced black tiger shrimp Penaeus monodon. The full-length sequences of PmPacifastin-like and its homologue LvPacifastin-like from the Pacific white shrimp Litopenaeus vannamei were determined. Sequence analysis revealed that both sequences contained thirteen conserved pacifastin light chain domains (PLDs), followed by two putative kunitz domains. Expression analysis demonstrated that the PmPacifastin-like transcript was expressed in all tested shrimp tissues and larval developmental stages, and its expression responded to Vibrio harveyi challenge. To gain insight into the functional roles of PmPacifastin-like protein, the in vivo RNA interference experiment was employed; the results showed that PmPacifastin-like depletion strongly increased PO activity. Interestingly, suppression of PmPacifastin-like also down-regulated the expression of the proPO-activating enzyme PmPPAE2 transcript; the PmPacifastin-like transcript was down-regulated after the PmproPO1/2 transcripts were silenced. Taken together, these results suggest that PmPacifastin-like is important in the shrimp proPO system and may play an essential role in shrimp immune defense against bacterial infection. These results also expand the knowledge of how pacifastin-related protein participates in the negative regulation of the proPO system in shrimp.
