Differential analysis of the haemolymph proteome of Carcinus maenas parasitized by Sacculina carcini (Cirripeda, Rhizocephala) reveals potential mechanisms of parasite control. FISH & SHELLFISH IMMUNOLOGY 2023; 141:109064. [PMID: 37689227 DOI: 10.1016/j.fsi.2023.109064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/22/2023] [Revised: 09/03/2023] [Accepted: 09/06/2023] [Indexed: 09/11/2023]
Abstract
Sacculina carcini is an endoparasite of the green crab, Carcinus maenas. This parasite induces behavioural changes in its host and affects its metabolism by inhibiting moulting and reproduction. Using a proteomic approach in mass spectrometry, we studied the haemolymph proteomes of healthy and parasitized wild green crabs from Brittany, France to identify proteins that are differentially expressed as a consequence of parasitization. We also investigated specific proteins involved in reproduction, moulting, and immunity. We detected 77 proteins for females and 53 proteins for males that were differentially present between the healthy and parasitized crabs, some of which were sex-specific. Detection of these differentially expressed proteins suggests that the parasite can inhibit and promote different aspects of the immune response of the host. Sacculina appears to inhibit host melanisation for self-protection, while promoting the presence of immune factors, such as antimicrobial peptides to cope with possible bacterial superinfections. Moreover, one protein, juvenile hormone esterase-like carboxylesterase, was 17-times more abundant in parasitized crabs than in healthy crabs and may be responsible for inhibiting moulting and reproduction in parasitized crabs, thus ensuring the success of Sacculina reproduction.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2023; 147:104760. [PMID: 37331675 DOI: 10.1016/j.dci.2023.104760] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 06/13/2023] [Accepted: 06/15/2023] [Indexed: 06/20/2023]
Abstract
Hemolymph is the circulatory fluid that fills the body cavity of crustaceans, analogous to blood in vertebrates. Hemolymph coagulation, similar to blood clotting in vertebrates, plays a crucial role in wound healing and innate immune responses. Despite extensive studies on the clotting process in crustaceans, no comparative quantitative analysis of the protein composition of non-clotted and clotted hemolymph in any decapod has been reported. In this study, we used label-free protein quantification with high-resolution mass spectrometry to identify the proteomic profile of hemolymph in crayfish and quantify significant changes in protein abundances between non-clotted and clotted hemolymph. Our analysis identified a total of two-hundred and nineteen proteins in both hemolymph groups. Furthermore, we discussed the potential functions of the top most high and low-abundant proteins in hemolymph proteomic profile. The quantity of most of the proteins was not significantly changed during coagulation between non-clotted and clotted hemolymph, which may indicate that clotting proteins are likely pre-synthesized, allowing for a swift coagulation response to injury. Four proteins still showed abundance differences (p < 0.05, fold change>2), including C-type lectin domain-containing proteins, Laminin A chain, Tropomyosin, and Reverse transcriptase domain-containing proteins. While the first three proteins were down-regulated, the last one was up-regulated. The down-regulation of structural and cytoskeletal proteins may affect the process of hemocyte degranulation needed for coagulation, while the up-regulation of an immune-related protein might be attributed to the phagocytosis ability of viable hemocytes during coagulation.

Abstract
One of the significant limitations of aquaculture worldwide is the prevalence of divalent copper (Cu). Crayfish (Procambarus clarkii) are economically important freshwater species adapted to a variety of environmental stimuli, including heavy metal stresses; however, large-scale transcriptomic data of the hepatopancreas of crayfish in response to Cu stress are still scarce. Here, integrated comparative transcriptome and weighted gene co-expression network analyses were initially applied to investigate gene expression profiles of the hepatopancreas of crayfish subjected to Cu stress for different periods. As a result, 4662 significant differentially expressed genes (DEGs) were identified following Cu stress. Bioinformatics analyses revealed that the "focal adhesion" pathway was one of the most significantly upregulated response pathways following Cu stress, and seven DEGs mapped to this pathway were identified as hub genes. Furthermore, the seven hub genes were examined by quantitative PCR, and each was found to have a substantial increase in transcript abundance, suggesting a critical role of the "focal adhesion" pathway in the response of crayfish to Cu stress. Our transcriptomic data can be a good resource for the functional transcriptomics of crayfish, and these results may provide valuable insights into the molecular response mechanisms underlying crayfish to Cu stress.

Sequence, Expression, and Anti-GCRV Function of the Ferritin from the Grass Carp, Ctenopharyngodon idellus. Int J Mol Sci 2022; 23:ijms23126835. [PMID: 35743279 PMCID: PMC9224801 DOI: 10.3390/ijms23126835] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2022] [Revised: 06/13/2022] [Accepted: 06/15/2022] [Indexed: 11/17/2022] Open
Abstract
Ferritin possesses an immune function to defend against pathogen infection. To elucidate the immunity-protecting roles of ferritin from Ctenopharyngodon idellus (Ciferritin) against virus infection, the cDNA and promoter sequences of Ciferritin were determined, and the correlations between Ciferrtin expressions and promoter methylation levels were analyzed. In addition, the functional role of Ciferrtin on GCRV (grass carp reovirus) infection was assessed. The full-length cDNA of Ciferritin is 1053 bp, consists of a 531 bp open-reading frame, and encodes 176 amino acids. Ciferritin showed the highest sequence identity with the ferritin middle subunit of Mylopharyngodon piceus (93.56%), followed by the subunits of Megalobrama amblycephala and Sinocyclocheilus rhinocerous. Ciferritin contains a conserved ferritin domain (interval: 10−94 aa), and the caspase recruitment domain (CARD) and Rubrerythrin domain were also predicted. In the spleen and kidney, significantly higher Ciferritin expressions were observed at 6, 12, 24, or 168 h post GCRV infection than those in the PBS injection group (p < 0.05). The Ciferrtin expression level in the progeny of maternal-immunized grass carp was significantly higher than that in the progeny of common grass carp (p < 0.05). Ciferritin promoter methylation level in the progeny from common grass carp was 1.27 ± 0.15, and in the progeny of the maternal-immunized group was 1.00 ± 0.14. In addition, methylation levels of “CpG9” and “CpG10” loci were significantly lower in the progeny of maternal-immunized fish than those in the common group. Except for the “CpG5”, methylation levels of all other detected “CpG” loci negatively correlated with Ciferritin expression levels. Furthermore, the total methylation level of “CpG1−10” negatively correlated with the Ciferritin expressions. The Ciferritin expression level was significantly up-regulated, and the VP7 protein levels were significantly reduced, at 24 h post GCRV infection in the Ciferritin over-expression cells (p < 0.05). The results from the present study provide sequence, epigenetic modification and expression, and anti-GCRV functional information of Ciferritin, which provide a basis for achieving resistance to GCRV in grass carp breeding.

Iron Regulatory Protein 1 Inhibits Ferritin Translation Responding to OsHV-1 Infection in Ark Clams, Scapharca Broughtonii. Cells 2022; 11:cells11060982. [PMID: 35326435 PMCID: PMC8947174 DOI: 10.3390/cells11060982] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Revised: 03/11/2022] [Accepted: 03/11/2022] [Indexed: 02/04/2023] Open
Abstract
Elemental iron is an indispensable prosthetic group of DNA replication relative enzymes. The upregulation of ferritin translation by iron regulatory proteins (IRP1) in host cells is a nutritional immune strategy to sequester available iron to pathogens. The efficient replication of Ostreid herpesvirus 1 (OsHV-1), a lethal dsDNA virus among bivalves, depends on available iron. OsHV-1 infection was found to trigger iron limitation in ark clams; however, it is still an enigma how OsHV-1 successfully conducted rapid replication, escaping host iron limitations. In this study, we identified the IRP1 protein (designated as SbIRP-1) in the ark clam (Scapharca broughtonii) and found it could bind to the iron-responsive element (IRE) of ferritin (SbFn) mRNA based on electrophoretic mobility shift assay (EMSA). Knockdown of SbIRP-1 expression (0.24 ± 1.82-fold of that in NC group, p < 0.01) by RNA interference resulted in the accumulation of SbFn in hemocytes (1.79 ± 0.01-fold, p < 0.01) post-24 h of enhanced RNA interference injection. During OsHV-1 infection, SbFn mRNA was significantly upregulated in hemocytes from 24 h to 60 h, while its protein level was significantly reduced from 24 h to 48 h, with the lowest value at 36 h post-infection (0.11 ± 0.01-fold, p < 0.01). Further analysis by RNA immunoprecipitation assays showed that OsHV-1 could enhance the binding of SbIRP-1 with the SbFn IRE, which was significantly increased (2.17 ± 0.25-fold, p < 0.01) at 36 h post-infection. Consistently, SbIRP-1 protein expression was significantly increased in hemocytes from 12 h to 48 h post OsHV-1 infection (p < 0.01). In conclusion, the results suggest that OsHV-1 infection could suppress post-transcriptional translation of SbFn through the regulation of SbIRP-1, which likely contributes to OsHV-1 evasion of SbFn-mediating host iron limitation.

Conservative and Atypical Ferritins of Sponges. Int J Mol Sci 2021; 22:ijms22168635.

Abstract
Ferritins comprise a conservative family of proteins found in all species and play an essential role in resistance to redox stress, immune response, and cell differentiation. Sponges (Porifera) are the oldest Metazoa that show unique plasticity and regenerative potential. Here, we characterize the ferritins of two cold-water sponges using proteomics, spectral microscopy, and bioinformatic analysis. The recently duplicated conservative HdF1a/b and atypical HdF2 genes were found in the Halisarca dujardini genome. Multiple related transcripts of HpF1 were identified in the Halichondria panicea transcriptome. Expression of HdF1a/b was much higher than that of HdF2 in all annual seasons and regulated differently during the sponge dissociation/reaggregation. The presence of the MRE and HRE motifs in the HdF1 and HdF2 promotor regions and the IRE motif in mRNAs of HdF1 and HpF indicates that sponge ferritins expression depends on the cellular iron and oxygen levels. The gel electrophoresis combined with specific staining and mass spectrometry confirmed the presence of ferric ions and ferritins in multi-subunit complexes. The 3D modeling predicts the iron-binding capacity of HdF1 and HpF1 at the ferroxidase center and the absence of iron-binding in atypical HdF2. Interestingly, atypical ferritins lacking iron-binding capacity were found in genomes of many invertebrate species. Their function deserves further research.

Abstract
OBJECTIVE Mouse infection models are frequently used to study the host-pathogen interaction studies. However, due to several constraints, there is an urgent need for a simple, rapid, easy to handle, inexpensive, and ethically acceptable in vivo model system for studying the virulence of enteropathogens. Thus, the present study was performed to develop the larvae of Helicoverpa armigera as a rapid-inexpensive in vivo model system to evaluate the effect of Yersinia enterocolitica strain 8081 on its midgut via a label-free proteomic approach. RESULTS Helicoverpa armigera larvae fed with Yersinia enterocolitica strain 8081 manifested significant reduction in body weight and damage in midgut. On performing label-free proteomic study, secretory systems, putative hemolysin, and two-component system emerged as the main pathogenic proteins. Further, proteome comparison between control and Yersinia added diet-fed (YADF) insects revealed altered cytoskeletal proteins in response to increased melanization (via a prophenoloxidase cascade) and free radical generation. In concurrence, FTIR-spectroscopy, and histopathological and biochemical analysis confirmed gut damage in YADF insects. Finally, the proteome data suggests that the mechanism of infection and the host response in Y. enterocolitica-H. armigera system mimics Yersinia-mammalian gut interactions. CONCLUSIONS All data from current study collectively suggest that H. armigera larva can be considered as a potential in vivo model system for studying the enteropathogenic infection by Y. enterocolitica strain 8081.

[PMID: 32142875 DOI: 10.1016/j.fsi.2020.02.066] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/10/2020] [Revised: 02/24/2020] [Accepted: 02/29/2020] [Indexed: 06/10/2023]
Abstract
Fibrinogen-related proteins (FREPs) are widely found in both vertebrates as well as invertebrates, and they play a crucial role in host immunity. In this study, we isolated a novel ficolin gene (Mnfico3) from the oriental river prawn Macrobrachium nipponense. The complete cDNA sequence of Mnfico3 was 1133 bp long, containing an open reading frame of 765 bp coding for Mnfico3, a protein consisting of 254 amino acids. The Mnfico3 protein contained a putative N-terminal signal peptide and a fibrinogen-related protein domain present at the C-terminal. Phylogenetic analysis indicated that Mnfico3 had a closer evolutionary relationship with vertebrate ficolins than with its invertebrate homologues. Tissue distribution analysis indicated that Mnfico3 was predominantly expressed in muscle, in which its transcription was increased following bacterial challenge by Aeromonas veronii. Function analysis using recombinant protein revealed that rMnFico3 had broad-spectrum binding capacity to a variety of microorganisms and pathogen-associated molecular pattern (PAMP) ligands. Furthermore, rMnFico3 exhibited Ca2+-dependent agglutinating activity against microbes in vitro, and ability to attach to the hemocyte surface which promoted phagocytosis and subsequent clearance of invasive bacteria in vivo. Silencing rMnFico3 in prawn through RNAi did not alter the expression of antimicrobial peptide genes (ALF and Crustin). These results manifested that MnFico3 functioned as a potential pattern recognition receptor (PPR) to mediate cellular immune response by recognizing PAMPs, agglutinating invasive microbes, and promoting phagocytosis of hemocytes.

Abstract
Small heat shock proteins (sHSPs) are ATP-independent chaperones and involved into various physiological and stress processes. In the present study, a 28.6-kD sHSP coding gene, MnHSP28.6, was cloned and characterized from the oriental river prawn Macrobrachium nipponense. Tissue distribution analysis via qPCR and western blot revealed that MnHSP28.6 predominantly expressed in muscle. The temporal transcription of MnHSP28.6 in muscle after bacterial challenge, heavy metal exposure and doxorubicin (DOX) injection was investigated by qPCR. The results showed that the expression of MnHSP28.6 were strongly enhanced by both Cd2+ and Cu2+ exposure, as well as DOX injection, but not by bacterial infection. Aggregation assays showed that recombinant MnHSP28.6 could effectively prevent temperature-induced aggregation of citrate synthase, and reduction-induced aggregation of insulin in vitro. MnHSP28.6 also could protect muscle extracts from heat-induced protein denaturation and superoxide dismutase (SOD) inactivation. Expressing MnHSP28.6 in E. coli conferred host cell impressive protection against H2O2 compared to control. These results suggest a protective role of MnHSP28.6 in maintaining protein homeostasis, preventing aggregation, promoting resistance to heavy metal and keeping redox balance.
