Abstract
BACKGROUND Cystatin is a protease inhibitor that also regulates genes expression linked to inflammation and plays a role in defense and regulation. METHODS AND RESULTS Cystatin 10 (Smcys10) was cloned from Scophthalmus maximus and encodes a 145 amino acid polypeptide. The results of qRT-PCR showed that Smcys10 exhibited tissue-specific expression patterns, and its expression was significantly higher in the skin than in other tissues. The expression level of Smcys10 was significantly different in the skin, gill, head kidney, spleen and macrophages after Vibrio anguillarum infection, indicating that Smcys10 may play an important role in resistance to V. anguillarum infection. The recombinant Smcys10 protein showed binding and agglutinating activity in a Ca2+-dependent manner against bacteria. rSmcys10 treatment upregulated the expression of IL-10, TNF-α and TGF-β in macrophages of turbot and hindered the release of lactate dehydrogenase (LDH) from macrophages after V. anguillarum infection, which confirmed that rSmcys10 reduced the damage to macrophages by V. anguillarum. The NF-κB pathway was suppressed by Smcys10, as demonstrated by dual-luciferase analysis. CONCLUSIONS These results indicated that Smcys10 is involved in the host antibacterial immune response.

Abstract
Cystatins comprise a vast superfamily of evolutionary conserved proteins, predominantly recognized for their roles as endogenous inhibitors by regulating the activity of cysteine proteases. Emerging lines of research evidence also provides insight into their alternative roles in a spectrum of biological and pathological processes, including neurodegenerative disorders, tumor progression, inflammatory diseases, and immune response. Nowadays, various type-1 cystatins (stefins) have been demonstrated among a variety of discovered vertebrate groups, while little is known about the related homologue in cephalochordate amphioxus, which are repositioned at the base of the chordate phylum. In the present study, a single type-1 cystatin homologue in Branchiostoma japonicum was first successfully cloned and designated as Bjcystatin-1. The deduced Bjcystatin-1 protein is structurally characterized by the presence of typical wedge-shaped cystatin features, including the 'QxVxG' and 'Px' motif, as well as the conserved N-terminal glycine residue. Phylogenomic analyses utilizing different cystatin counterparts affirmed the close evolutionary relationship of Bjcystatin-1 and type-1 cystatin homologue. Bjcystatin-1 was predominantly expressed in the gills and hind-gut in a tissue-specific pattern, and its expression was remarkably up-regulated in response to challenge with bacteria or their signature molecules LPS and LTA, suggesting the involvement in immune response. Additionally, the recombinant Bjcystatin-1 (rBjcystatin-1) protein showed significant inhibitory activity towards papain and binding ability to LPS and LTA, indicating its hypothesized role as a pattern recognition receptor in immune response. Subcellular localization results also showed that Bjcystatin-1 was located in the cytoplasm and nucleus, and its overexpression could attenuate the activation of LPS-induced nuclear transcription factors NF-κB. Taken together, our study suggests that amphioxus Bjcystatin-1 acts as a dual role in protease inhibitor and an immunocompetent factor, providing new insights into the immune defense effect of type-1 cystatin in amphioxus.

Abstract
The present study aims to explore the therapeutic effect of Stefin B on gouty arthritis (GA) and the polarization of macrophages in mice. Stefin B-overexpressed or knockdown M0 macrophages were constructed. The GA model was established in mice by injecting 25 mg/mL MSU, followed by a single injecting of Stefin B-overexpressing adenovirus vector (GA model + Stefin B OE) or an empty vector (GA model + Stefin B OE NC). Stefin B was found lowly expressed in M1 macrophages. CD206 was markedly upregulated and IL-10 release was signally increased in Stefin B-overexpressed macrophages. In gouty arthritis mice, marked redness and swelling were observed in the ankle joint. Dramatical infiltration of inflammatory cells was observed in the GA model and GA model + Stefin B OE NC groups, which was suppressed in the Stefin B OE group. Increased proportion of F4/80+CD86+ cells observed in GA mice was markedly repressed by Stefin B overexpression, accompanied by the declined level of Caspase-1 and IL-17. Collectively, Stefin B alleviated the GA in mice by inducing the M2 polarization of macrophages.

Abstract
Fish freshness consists of complex endogenous and exogenous processes; therefore, the use of a few parameters to unravel illicit practices could be insufficient. Moreover, the development of strategies for the identification of such practices based on additives known to prevent and/or delay fish spoilage is still limited. The paper deals with the identification of the effect played by a Cafodos solution on the conservation state of sea bass at both short-term (3 h) and long-term (24 h). Controls and treated samples were characterized by a multi-omic approach involving proteomics, lipidomics, metabolomics, and metagenomics. Different parts of the fish samples were studied (muscle, skin, eye, and gills) and sampled through a non-invasive procedure based on EVA strips functionalized by ionic exchange resins. Data fusion methods were then applied to build models able to discriminate between controls and treated samples and identify the possible markers of the applied treatment. The approach was effective in the identification of the effect played by Cafodos that proved to be different in the short- and long-term and complex, involving proteins, lipids, and small molecules to a different extent.

Genome-Wide Identification, Evolutionary Analysis, and Expression Patterns of Cathepsin Superfamily in Black Rockfish (Sebastes schlegelii) following Aeromonas salmonicida Infection. Mar Drugs 2022; 20:md20080504. [PMID: 36005507 PMCID: PMC9409823 DOI: 10.3390/md20080504] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Revised: 07/24/2022] [Accepted: 07/26/2022] [Indexed: 01/27/2023] Open
Abstract
Cathepsins are lysosomal cysteine proteases belonging to the papain family and play crucial roles in intracellular protein degradation/turnover, hormone maturation, antigen processing, and immune responses. In the present study, 18 cathepsins were systematically identified from the fish S. schlegelii genome. Phylogenetic analysis indicated that cathepsin superfamilies are categorized into eleven major clusters. Synteny and genome organization analysis revealed that whole-genome duplication led to the expansion of S. schlegelii cathepsins. Evolutionary rate analyses indicated that the lowest Ka/Ks ratios were observed in CTSBa (0.13) and CTSBb (0.14), and the highest Ka/Ks ratios were observed in CTSZa (1.97) and CTSZb (1.75). In addition, cathepsins were ubiquitously expressed in all examined tissues, with high expression levels observed in the gill, intestine, head kidney, and spleen. Additionally, most cathepsins were differentially expressed in the head kidney, gill, spleen, and liver following Aeromonas salmonicida infection, and their expression signatures showed tissue-specific and time-dependent patterns. Finally, protein–protein interaction network (PPI) analyses revealed that cathepsins are closely related to a few immune-related genes, such as interleukins, chemokines, and TLR genes. These results are expected to be valuable for comparative immunological studies and provide insights for further functional characterization of cathepsins in fish species.

Abstract
Cystatin B is a cysteine protease inhibitor that plays a crucial role in immune response. Nevertheless, the molecular mechanism of fish Cystatin B in virus replication remains obscure. In this study, we identified and characterized Cystatin B (Ec-CysB) in the orange-spotted grouper (Epinephelus coioides). The Ec-CysB encoded a 100-amino acid protein with the conserved QXVXG motif, PC motif and cysteine protease inhibitory motif, which shared high identities with reported Cystatin B. The abundant transcriptional level of Ec-CysB was found in gill, intestine and head kidney. And the Ec-CysB expression was significantly up-regulated in spleen after infection with Singapore grouper iridovirus (SGIV) in vitro. Subcellular localization analysis revealed that Ec-CysB was distributed mainly in the cytoplasm and nucleus. Further studies showed that overexpression of Ec-CysB in vitro significantly increased SGIV replication and virus-induced cell apoptosis, but replication of SGIV was inhibited by knockdown or mutant of Ec-CysB. Moreover, overexpression of Ec-CysB significantly inhibited the interferon (IFN), interferon-stimulated response element (ISRE) promoter activities, and enhanced apoptosis-related transcription factors p53 promoter activities. Collectively, our results suggest that Ec-CysB affect viral replication and virus-induced cell apoptosis, which will help us to explore its potential functions during SGIV infection.

Abstract
Cystatin proteins are known to form a superfamily of cysteine protease inhibitors, which play a key role in protein degradation and are related to different physiological processes, such as development and immunity. Currently, numerous immunoregulatory proteins, such as cystatins, are being used in the control and prevention of diseases in aquaculture. Thus, the objective of this study was to produce recombinant cystatin (rCYST-B) from the red piranha Pygocentrus nattereri and to evaluate its effect on bacterial growth. The gene that encodes cystatin-B was isolated from the spleen of P. nattereri and cloned in an expression system. The protein was produced via a heterologous system involving the yeast Pichia pastoris X-33. The inhibitory activity of purified cystatin-B was evaluated on papain using different concentrations (0–80.0 μg/μL) of rCYST-B. The bacteriostatic action of the protein was evaluated using the Kirby-Bauer method on the growth of Escherichia coli and Bacillus subtilis. rCYST-B showed 100% inhibition at a concentration of 60 μg/μL. Moreover, the bacteriostatic activity of E. coli and B. subtilis showed inhibition of 40.36 and 49.08% compared to the negative control (phosphate buffer), respectively. These results suggest that recombinant CYST-B has biotechnological potential for use in aquaculture.

Abstract
Objective To investigate the value of preoperative urinary nuclear matrix protein 22 (NMP22) and Cystatin B (CSTB) expressions in evaluating the postoperative recurrence of bladder cancer. Methods The clinical case data of 102 patients with bladder cancer who underwent surgical treatment from January 2017 to January 2022 were collected, and the patients were divided into a recurrence group (n = 54) and nonrecurrence group (n = 48) according to whether the patients recurred after surgery, and the preoperative NMP22 and CSTB expression levels between the two groups were compared. Receiver operating curve (ROC) was used to analyze the evaluation value of preoperative NMP22 and CSTB expression in patients with bladder cancer postoperative recurrence. Logistic multivariate regression method was used to analyze the correlation between preoperative NMP22 and CSTB expression and postoperative bladder cancer recurrence. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of NMP22 and CSTB single detection and combined detection were evaluated for postoperative recurrence of bladder cancer. Results The preoperative expression levels of NMP22 and CSTB in the recurrence group were significantly higher than those in the nonrecurrence group (P < 0.05). The results of ROC curve analysis showed that the AUC of preoperative NMP22 and CSTB expression levels to assess postoperative recurrence of bladder cancer was 0.696 and 0.659, respectively (P < 0.05). Logistic multivariate regression analysis showed that preoperative NMP22 and CSTB overexpression was an independent risk factor for postoperative recurrence of bladder cancer (OR = 1.042, 2.307, P < 0.05). The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of preoperative NMP22 combined with CSTB in evaluating bladder cancer recurrence after surgery were higher than those of preoperative NMP22 and CSTB alone, and the differences were statistically significant (P < 0.05). Conclusion Preoperative NMP22 and CSTB conveying is hardly interrelated to postoperative recurrence of bladder carcinoma and has certain appraisal worth for postoperative recurrence of bladder carcinoma, and the combined testing of the two has a taller appraisal worth. NMP22 combined with CSTB detection will help to detect postoperative recurrence of bladder cancer and formulate effective treatment measures in time.

Abstract
Cystatins are a diverse group of cysteine protease inhibitors widely present among various organisms. Beyond their protease inhibitor function, cystatins play a crucial role in diverse pathophysiological conditions in animals, including neurodegenerative disorders, tumor progression, inflammatory diseases, and immune response. However, the role of cystatins in immunity against viral and bacterial infections in fish remains to be elucidated. In this study, the cystatin B from big-belly seahorse, Hippocampus abdominalis, designated as HaCSTB, was identified and characterized. HaCSTB shared the highest homology with type 1 cystatin family members of teleosts and had three cystatin catalytic domains with no signal peptides or disulfide bonds. HaCSTB transcripts were mainly expressed in peripheral blood cells (PBCs), followed by the testis and pouch of healthy big-belly seahorses. Immune challenge with lipopolysaccharides (LPS), polyinosinic:polycytidylic acid (Poly I:C), and Streptococcus iniae induced upregulation of relative HaCSTB mRNA expression in PBCs. Subcellular localization analysis revealed the distribution of HaCSTB in the cytosol, mitochondria, and nuclei of fathead minnow cells (FHM). Recombinant HaCSTB (rHaCSTB) exhibited potent in vitro inhibitory activity against papain, a cysteine protease, in a concentration-, pH-, and temperature-dependent manner. Overexpression of HaCSTB in viral hemorrhagic septicemia virus (VHSV)-susceptible FHM cells increased cell viability and reduced VHSV-induced apoptosis. Collectively, these results suggest that HaCSTB might engage in the teleostean immune protection against bacteria and viruses.

Sudharson S, Kalic T, Hafner C, Breiteneder H. Newly defined allergens in the WHO/IUIS Allergen Nomenclature Database during 01/2019-03/2021. Allergy 2021; 76:3359-3373. [PMID: 34310736 PMCID: PMC9290965 DOI: 10.1111/all.15021] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2021] [Accepted: 07/21/2021] [Indexed: 01/03/2023]
Abstract
The WHO/IUIS Allergen Nomenclature Database (http://allergen.org) provides up‐to‐date expert‐reviewed data on newly discovered allergens and their unambiguous nomenclature to allergen researchers worldwide. This review discusses the 106 allergens that were accepted by the Allergen Nomenclature Sub‐Committee between 01/2019 and 03/2021. Information about protein family membership, patient cohorts, and assays used for allergen characterization is summarized. A first allergenic fungal triosephosphate isomerase, Asp t 36, was discovered in Aspergillus terreus. Plant allergens contained 1 contact, 38 respiratory, and 16 food allergens. Can s 4 from Indian hemp was identified as the first allergenic oxygen‐evolving enhancer protein 2 and Cic a 1 from chickpeas as the first allergenic group 4 late embryogenesis abundant protein. Among the animal allergens were 19 respiratory, 28 food, and 3 venom allergens. Important discoveries include Rap v 2, an allergenic paramyosin in molluscs, and Sal s 4 and Pan h 4, allergenic fish tropomyosins. Paramyosins and tropomyosins were previously known mainly as arthropod allergens. Collagens from barramundi, Lat c 6, and salmon, Sal s 6, were the first members from the collagen superfamily added to the database. In summary, the addition of 106 new allergens to the previously listed 930 allergens reflects the continuous linear growth of the allergen database. In addition, 17 newly described allergen sources were included.

Identification of Antimicrobial Peptide Genes in Black Rockfish Sebastes schlegelii and Their Responsive Mechanisms to Edwardsiella tarda Infection. BIOLOGY 2021; 10:biology10101015. [PMID: 34681113 PMCID: PMC8533284 DOI: 10.3390/biology10101015] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Revised: 09/18/2021] [Accepted: 09/20/2021] [Indexed: 01/01/2023]
Abstract
The black rockfish, Sebastes schlegelii, is a typical viviparous teleost, which belongs to the family Scorpaenidae. Due to its high economic and ecological values, S. schlegelii has been widely cultured in East Asian countries. With the enlargement of cultivation scale, bacterial and viral diseases have become the main threats to the farming industry of S. schlegelii, which have resulted in significant economic losses. In this study, Illumina shotgun sequencing, single-molecule real-time (SMRT) sequencing, 10× genomics and high-throughput chromosome conformation capture (Hi-C) technologies were collectively applied to assemble the genome of S. schlegelii. Then, we identified the antimicrobial peptide genes (AMPs) in the S. schlegelii genome. In total, 214 AMPs were identified in the S. schlegelii genome, which can be divided into 33 classes according to the annotation and cataloging of the Antimicrobial Peptides Database (APD3). Among these AMPs, thrombin-derived C-terminal peptide (TCP) was the dominant type, followed by RegIIIgamma and chemokine. The amino acid sequences of the TCP, cgUbiquitin, RegIIIalpha, RegIIIgamma, chemokine shared 32.55%, 42.63%, 29.87%, 28.09%, and 32.15% similarities among the same type in S. schlegelii. Meanwhile, the expression patterns of these AMPs in nine healthy tissues and at different infection time points in intestine were investigated. The results showed that the numbers and types of AMPs that responded to Edwardsiella tarda infection gradually increased as the infection progressed. In addition, we analyzed the phylogenetic relationships of hepcidins in teleost. The identification of AMPs based on the whole genome could provide a comprehensive database of potential AMPs, and benefit for the understanding of the molecular mechanisms of immune responses to E. tarda infection in S. schlegelii. This would further offer insights into an accurate and effective design and development of AMP for aquaculture therapy in the future.

Complement genes in black rockfish (Sebastods schlegelii): genome-wide identification, evolution and their potential functions in response to Vibrio anguillarum infection. FISH & SHELLFISH IMMUNOLOGY 2021; 114:119-131. [PMID: 33930548 DOI: 10.1016/j.fsi.2021.04.020] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/08/2021] [Revised: 03/29/2021] [Accepted: 04/21/2021] [Indexed: 06/12/2023]
Abstract
As complex components of innate immune system, members of complement system play crucial roles during the process of defensing against pathogens. Black rockfish (Sebastes schlegelii) is one of the important aquaculture species in East Asian. However, studies of complement genes in black rockfish and its related immune activities are still lacking. Therefore, a total of 112 members of the complement genes were identified from the genome of black rockfish and were classified into five subgroups. According to their functional annotations, 30 genes belonged to pattern recognition, 6 genes belonged to proteases, 14 genes belonged to complement components, 36 genes belonged to receptors, and 26 genes belonged to regulators. It can be found that many complement genes evolved into multi-copies, especially in teleost, which may be influenced by whole-genome duplication or tandem duplication events. Complement genes were randomly distributed on 22 chromosomes. The number of introns of complement genes varied from 1 to 70. Results of the expression patterns of 10 randomly selected genes from 5 subtypes response to Vibrio anguillarum infection revealed that most of the members of the complement genes were induced in gill and skin. In contrast, most genes in intestine showed downregulation. This study systematically characterized and analyzed the complement genes in black rockfish and provided new insights into their functions responding to bacterial infection.

Bae H, Yang C, Lim W, Song G. Identification of tissue-specific expression of CXCL14 in black rockfish (Sebastes schlegelii). FISH & SHELLFISH IMMUNOLOGY 2021; 112:135-142. [PMID: 33746059 DOI: 10.1016/j.fsi.2021.03.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/09/2020] [Revised: 02/18/2021] [Accepted: 03/15/2021] [Indexed: 06/12/2023]
Abstract
CXCL14 is a chemokine which is orthologous in mammals and fish. CXCL14 has a functional role in different organs, with immunomodulatory functions in mammals, but its expression and function in fish is not well known. Moreover, it shows no effects related to immunity in the central nervous system or the reproductive tract in diverse species. Black rockfish (Sebastes schlegelii) is an economically important fish in Asian countries, whose CXCL14 expression pattern is yet to be understood. In this study, the homology of the CXCL14 amino acid sequence in S. schlegelii was compared with that in other species, including fish. Moreover, in situ hybridization analysis revealed that it was highly expressed in the brain and ovary of S. schlegelii. Taken together, we identified for the first time, the cell-specific expression of CXCL14 in S. schlegelii.
