Abstract
Th17 is a lymphocyte T helper (Th) subpopulation relevant in the control and regulation of the immune response characterized by the production of interleukin (IL)-17. This crucial cytokine family acts through their binding to the IL-17 receptors (IL-17R), having up to six members. Although the biology of fish Th17 is well-recognized, the molecular and functional characterization of IL-17 and IL-17R has been limited. Thus, our aim was to identify and characterize the IL-17R repertory and regulation in the two main Mediterranean cultured fish species, the gilthead seabream (Sparus aurata) and the European sea bass (Dicentrarchus labrax). Our in silico results showed the clear identification of six members in each fish species, from IL-17RA to IL-17RE-like, with well-conserved gene structure and protein domains with their human orthologues. All of them showed wide and constitutive transcription in naïve tissues but with highest levels in mucosal tissues, namely skin, gill or intestine. In leucocytes, T mitogens showed the strongest up-regulation in most of the il17 receptors though il17ra resulted in inhibition by most stimulants. Interestingly, in vivo nodavirus infection resulted in alterations on the transcription of il17 receptors. While nodavirus infection led to some increments in the il17ra, il17rb, il17rc and il17rd transcripts in the susceptible European sea bass, many down-regulations were observed in the resistant gilthead seabream. Our data identify the presence and conservation of six coding IL-17R in gilthead seabream and European sea bass as well as their differential regulation in vitro and upon nodavirus infection.

Abstract
The skin, the largest organ, functions as a primary defense mechanism. Epidermal stem cells supply undifferentiated keratinocytes that differentiate as they migrate toward the outermost skin layer. Although such a replenishment process is disrupted in various human skin diseases, its underlying mechanisms remain elusive. With high-resolution live imaging and in vivo manipulations, we revealed that Notch signaling between keratinocytes is mediated by signaling filopodia called cytonemes and is essential for proper keratinocyte differentiation and proliferation. Inhibiting keratinocyte cytonemes reduced Notch expression within undifferentiated keratinocytes, leading to abnormal differentiation and hyperproliferation, resembling human skin disease phenotypes. Overproduction of Interleukin (IL)-17 signal, associated with skin diseases like psoriasis, induces psoriatic phenotypes via cytonemes in zebrafish. Our study suggests that intercellular signaling between keratinocytes through cytonemes is critical for epidermal maintenance, and its misregulation could be an origin of human skin diseases.

Agonistic effect of peptides derived from a truncated HMGB1 acidic tail sequence in TLR5 from Salmo salar. FISH & SHELLFISH IMMUNOLOGY 2024; 144:109219.

Abstract
Based on the structural knowledge of TLR5 surface and using blind docking platforms, peptides derived from a truncated HMGB1 acidic tail from Salmo salar was designed as TLR5 agonistic. Additionally, a template peptide with the native N-terminal of the acidic tail sequence as a reference was included (SsOri). Peptide binding poses complexed on TLR5 ectodomain model from each algorithm were filtrated based on docking scoring functions and predicted theoretical binding affinity of the complex. The best peptides, termed 6WK and 5LWK, were selected for chemical synthesis and experimental functional assay. The agonist activity by immunoblotting and immunocytochemistry was determined following the NF-κBp65 phosphorylation (p-NF-κBp65) and the nuclear translocation of the NF-κBp65 subunit from the cytosol, respectively. HeLa cells stably expressing a S. salar TLR5 chimeric form (TLR5c7) showed increased p-NF-κBp65 levels regarding extracts from flagellin-treated cells. No statistically significant differences (p > 0.05) were found in the detected p-NF-κBp65 levels between cellular extracts treated with peptides or flagellin by one-way ANOVA. The image analysis of NF-κBp65 immunolabeled cells obtained by confocal microscopy showed increased nuclear NF-κBp65 co-localization in cells both 5LWK and flagellin stimulated, while 6WK and SsOri showed less effect on p65 nuclear translocation (p < 0.05). Also, an increased transcript expression profile of proinflammatory cytokines such as TNFα, IL-1β, and IL-8 in HKL cells isolated from Salmo salar was evidenced in 5LWK - stimulated by RT-PCR analysis. Overall, the result indicates the usefulness of novel peptides as a potential immunostimulant in S. salar.

Abstract
Interleukins (ILs) are a subgroup of secreted cytokines, which are molecules involved in the intercellular regulation of the immune system. In this study, 12 IL homologs were cloned and functionally identified from obscure puffer Takifugu obscurus, and they were termed as ToIL-1β, ToIL-1, ToIL-6, ToIL-10, ToIL-11, ToIL-12, ToIL-17, ToIL-18, ToIL-20, ToIL-24, ToIL-27, and ToIL-34. Multiple alignment results showed that except for ToIL-24 and ToIL-27, other deduced ToIL proteins shared typical characteristics and structure with other known fish ILs. Phylogenetic analysis revealed that 12 ToILs were evolutionarily closely related to their counterparts in other selected vertebrates. Tissue distribution assay demonstrated that the mRNA transcripts of most ToIL genes were constitutively expressed in all tissues examined, with relatively high expression in immune tissues. Following Vibrio harveyi and Staphylococcus aureus infection, the expression levels of 12 ToILs in the spleen and liver were significantly upregulated, and their response over time varied. Taken together, these data were discussed accordingly with the ToIL expression and the immune response under the different situations tested. The results suggest that the 12 ToIL genes are involved in the antibacterial immune response in T. obscurus.

Abstract
Recurrent miscarriage (RM) is a condition defined as having three or more consecutive pregnancy losses before the 20 weeks of pregnancy. The present study was undertaken to investigate association of Interleukin-17A (IL-17A) rs2275913 polymorphism with RM. To this end, we searched the international databases (Web of Science, PubMed, Embase, and Scopus) and extracted studies investigating the association of IL-17A rs2275913 polymorphism with RM using the appropriate keywords. The collected data were analyzed with the random-effects model and STATA (version 14). A total of five studies met the eligibility criteria, and total sample size was 998 subjects. Mean age of the cases and controls were 31.41 ± 4.16 and 30.56 ± 3.5 years, respectively. Our results disclosed a significant relationship of the IL-17A rs2275913 AA genotype [odds ratio (OR)=1.68; 95% confidence interval (CI)=1.16- 2.43; I2=19; P=0.294) with RM. There was no statistically significant correlation between IL-17Ars2275913 GG genotype (OR=1.04; 95% CI=0.64-1.7; I2=59.5; P=0.042) and GA genotype (OR=0.85; 95% CI=0.65-1.12; I2=19.1; P=0.293) with RM. Our findings revealed that the IL-17A rs2275913 polymorphism is associated with RM, and the AA genotype of this polymorphism increased possibility of being involved in RM.

Risk of candidiasis associated with interleukin-17 inhibitors: Implications and management. Mycology 2023; 15:30-44. [PMID: 38558839 PMCID: PMC10977001 DOI: 10.1080/21501203.2023.2265664] [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: 06/07/2023] [Accepted: 09/27/2023] [Indexed: 04/04/2024] Open
Abstract
The application of interleukin-17 (IL-17) inhibitors, including secukinumab, ixekizumab, brodalumab, and bimekizumab, are associated with elevated risk of candidiasis. These medications interfere with the IL-17 pathway, which is essential for maintaining mucosal barriers and coordinating the immune response against Candida species. The observational data and clinical trials demonstrate the increased incidence of candidiasis in individuals treated with IL-17 inhibitors. Brodalumab and bimekizumab pose a greater risk than secukinumab in eliciting candidiasis, whereas the data regarding ixekizumab are equivocal. Higher doses and prolonged treatment duration of IL-17 inhibitors increase the risk of candidiasis by compromising the immune response against Candida species. Prior to prescribing IL-17 inhibitors, healthcare professionals should comprehensively evaluate patients' medical histories and assess their risk factors. Patients should be educated on the signs and symptoms of candidiasis to facilitate early detection and intervention. Future research should focus on identifying the risk factors associated with candidiasis in patients receiving IL-17 inhibitors. Prospective studies and long-term surveillance are required to explore the impact of specific inhibitors on the incidence and severity of candidiasis and to evaluate the effectiveness of combination therapies, such as concurrent use of IL-17 inhibitors and prophylactic antifungal agents.

Abstract
The neurohormone crustacean female sex hormone (CFSH) contains a highly conserved interleukin-17 (IL-17) domain in the mature peptide. Although CFSH has been demonstrated to stimulate female sexual differentiation in crustaceans, its receptors (CFSHR) have been poorly reported. The present study identified an IL-17 receptor (named Lvit-IL-17R), a candidate of CFSHR, from the protandric simultaneous hermaphroditic (PSH) shrimp Lysmata vittata through GST pulldown assays and RNAi experiments. Lvit-IL-17R is a transmembrane protein with an SEFIR (similar expression as the fibroblast growth factor and IL-17R) domain, as determined through sequence analysis. A GST pulldown experiment confirmed the interactions between the type I CFSHs (CFSH1a and CFSH1b) and Lvit-IL-17R. Meanwhile, the RNAi results revealed that Lvit-IL-17R displays similar functions to type I CFSHs in regulating sexual differentiation and gonad development. In brief, Lvit-IL-17R is a potential receptor for type I CFSHs aimed at regulating the sexual differentiation of the PSH species. This study helps shed new light on the mechanism of sexual differentiation among crustaceans.

Abstract
BACKGROUND The IL-17 (interleukin 17) family consists of six structurally related pro-inflammatory cytokines, namely IL-17A to IL-17F. These cytokines have garnered significant scientific interest due to their pivotal role in the pathogenesis of various diseases. Notably, a specific subset of T-cells expresses IL-17 family members, highlighting their importance in immune responses against microbial infections. INTRODUCTION IL-17 cytokines play a critical role in host defense mechanisms by inducing cytokines and chemokines, recruiting neutrophils, modifying T-cell differentiation, and stimulating the production of antimicrobial proteins. Maintaining an appropriate balance of IL-17 is vital for overall health. However, dysregulated production of IL-17A and other members can lead to the pathogenesis of numerous inflammatory and autoimmune diseases. METHOD This review provides a comprehensive overview of the IL-17 family and its involvement in several inflammatory and autoimmune diseases. Relevant literature and research studies were analyzed to compile the data presented in this review. RESULTS IL-17 cytokines, particularly IL-17A, have been implicated in the development of various inflammatory and autoimmune disorders, including multiple sclerosis, Hashimoto's thyroiditis, systemic lupus erythematosus, pyoderma gangrenosum, autoimmune hepatic disorders, rheumatoid arthritis, psoriasis, psoriatic arthritis, ankylosing spondylitis, osteoarthritis, and graft-versus-host disease. Understanding the role of IL-17 in these diseases is crucial for developing targeted therapeutic strategies. CONCLUSION The significant involvement of IL-17 cytokines in inflammatory and autoimmune diseases underscores their potential as therapeutic targets. Current treatments utilizing antibodies against IL-17 cytokines and IL-17RA receptors have shown promise in managing these conditions. This review consolidates the understanding of IL-17 family members and their roles, providing valuable insights for the development of novel immunomodulators to effectively treat inflammatory and autoimmune diseases.

Abstract
Interleukin (IL)-17 is a proinflammatory cytokine and plays essential roles in adaptive and innate immune responses against bacterial and fungal infections. Especially in mammalian mucosal tissues, it is well known that innate immune responses via IL-17A and IL-17F, such as the production of antimicrobial peptides, are very important for microbiota control. In contrast, interesting insights into the functions of IL-17 have recently been reported in several teleost species, although little research has been conducted on teleost IL-17. In the present review, we focused on current insights on teleost IL-17 and speculated on the different or consensus parts of teleost IL-17 signaling compared to that of mammals. This review focuses on the role of teleost IL-17 in intestinal immunity. We expect that this review will encourage a further understanding of the roles and importance of IL-17 signaling in teleosts.

Abstract
Jade perch (Scortum barcoo) is a freshwater fish with substantial economic value, which has been widely cultivated all over the world. However, with the intensification and expansion of farming, several bacterial and viral diseases have occurred in jade perch. To understand the immune response of jade perch against Streptococcus agalactiae (Group B Streptococcus, GBS), we performed a histopathological examination and transcriptome sequencing of jade perch spleen after artificial bacterial infection. GBS infection can cause structural changes and even necrosis of the jade perch spleen, which may affect the survival of infected individuals. A total of 144,458 unigenes were obtained through de novo assembly of spleen transcriptome. Among them, 1821 unigenes were identified as DEGs, including 1415 up-regulated and 406 down-regulated unigenes in the infection group. Moreover, the analysis of GO and KEGG revealed that many GO terms and pathways were involved in the host immune response, such as Toll-like receptor signaling pathway, Cytokine-cytokine receptor interaction, and TNF signaling pathway. In addition, according to transcriptome data and qRT-PCR analysis, the expression levels of many cytokines that participate in the inflammatory response changed a lot after GBS infection. Overall, this transcriptomic analysis provided valuable information for studying the immune response of jade perch against bacterial infection.

Int J Biol Macromol 2022; 220:493-509. [PMID: 35981681 DOI: 10.1016/j.ijbiomac.2022.08.060] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2022] [Revised: 08/09/2022] [Accepted: 08/09/2022] [Indexed: 11/05/2022]
Abstract
In mammals, six interleukin-17 (IL-17) genes, as potent pro-inflammatory cytokines, all accelerate the inflammatory responses. In teleosts, seven IL-17 genes have been found in various species, but little is known about the function of teleost-specific IL-17N. In this study, teleost IL-17N and IL-17A/F2 genes all had six conserved cysteine residues forming three intrachain disulfide bridges, the length of three exons of teleost IL-17N gene was similar to that of teleost IL-17A/F2 gene, and the neighbor-joining (NJ) phylogenetic tree showed that teleost IL-17N was clustered with vertebrate IL-17A/F, implying that teleost IL-17N gene may be a paralog of teleost IL-17A/F gene. Pelteobagrus fulvidraco (Pf) IL-17N gene was highly expressed in the blood, brain and kidney of healthy yellow catfish. Pf_IL-17N transcript and protein were notably up-regulated in the spleen, head kidney, gill and kidney detected after Edwardsiella ictaluri infection. Lipopolysaccharides (LPS), polyinosinic-polycytidylic acid (Poly I:C) and peptidoglycan (PGN) also remarkably induced the expression of Pf_IL-17N in the isolated peripheral blood leucocytes (PBLs) of yellow catfish. These results reveal that Pf_IL-17N may play important roles in preventing the invasion of pathogens. Furthermore, the recombinant (r) Pf_IL-17N protein could significantly induce the mRNA expressions of inflammatory cytokines, chemokines and antimicrobial peptide genes in yellow catfish in vivo and in vitro, and it also notably promoted the phagocytosis of myeloid cells in the PBLs and the chemotaxis of the PBLs and gill leucocytes (GLs) in yellow catfish. Besides, though the rPf_IL-17N protein could induce and aggravate inflammation infiltration in the kidney of yellow catfish, it did not effectively and notably increase the survival rate of yellow catfish after E. ictaluri infection. Furthermore, the rPf_IL-17N protein could induce the mRNA expressions of nuclear factor kappa-B (NF-κB) and mitogen-activated protein kinase (MAPK) signal pathways related genes, and the inhibitor of NF-κB and MAPK signal pathways could restrain the rPf_IL-17N protein-induced inflammatory response. This study provides crucial evidence that the Pf_IL-17N may mediate inflammatory response to eliminate invasive pathogens.

Abstract
Cytokines belong to the most widely studied group of intracellular molecules involved in the function of the immune system. Their secretion is induced by various infectious stimuli. Cytokine release by host cells has been extensively used as a powerful tool for studying immune reactions in the early stages of viral and bacterial infections. Recently, research attention has shifted to the investigation of cytokine responses using mRNA expression, an essential mechanism related to pathogenic and nonpathogenic-immune stimulants in fish. This review represents the current knowledge of cytokine responses to infectious diseases in the common carp (Cyprinus carpio L.). Given the paucity of literature on cytokine responses to many infections in carp, only select viral diseases, such as koi herpesvirus disease (KHVD), spring viremia of carp (SVC), and carp edema virus disease (CEVD), are discussed. Aeromonas hydrophila is one of the most studied bacterial pathogens associated with cytokine responses in common carp. Therefore, the cytokine-based immunoreactivity raised by this specific bacterial pathogen is also highlighted in this review.

Abstract
Piscine orthoreovirus (PRV-1) infection causes heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon (Salmo salar). The virus is also associated with focal melanized changes in white skeletal muscle where PRV-1 infection of macrophages appears to be important. In this study, we studied the macrophage polarization into M1 (pro-inflammatory) and M2 (anti-inflammatory) phenotypes during experimentally induced HSMI. The immune response in heart with HSMI lesions was characterized by CD8+ and MHC-I expressing cells and not by polarized macrophages. Fluorescent in situ hybridization (FISH) assays revealed localization of PRV-1 in a few M1 macrophages in both heart and skeletal muscle. M2 type macrophages were widely scattered in the heart and were more abundant in heart compared to the skeletal muscle. However, the M2 macrophages did not co-stain for PRV-1. There was a strong cellular immune response to the infection in the heart compared to that of the skeletal muscle, seen as increased MHC-I expression, partly in cells also containing PRV-1 RNA, and a high number of cytotoxic CD8+ granzyme producing cells that targeted PRV-1. In skeletal muscle, MHC-I expressing cells and CD8+ cells were dispersed between myocytes, but these cells did not stain for PRV-1. Gene expression analysis by RT-qPCR complied with the FISH results and confirmed a drop in level of PRV-1 following the cell mediated immune response. Overall, the results indicated that M1 macrophages do not contribute to the initial development of HSMI. However, large numbers of M2 macrophages reside in the heart and may contribute to the subsequent fast recovery following clearance of PRV-1 infection.

Abstract
Interleukin 17C (IL17C) is a cytokine that regulates innate immunity by recruiting antimicrobial peptides and pro-inflammatory cytokines. In this study, we characterized properties of IL-17C from Amphiprion clarkii also known as yellowtail clownfish (AcIL-17C). The AcIL-17C gene is 489 base pairs long and encodes a 163 amino acid long protein. AcIL-17C includes a signal peptide for localization in the extracellular space and comprises the IL-17 domain. The transcription analysis revealed that AcIL-17C mRNA was ubiquitously expressed in 12 tested tissues. Blood cells treated with polyinosinic:polycytidylic acid (poly (I:C)), lipopolysaccharides (LPS), and Vibrio harveyi, AcIL-17C mRNA expression was upregulated at 6 h (following poly (I:C) and LPS treatments) and at 24 h post-injection (following all treatments). The downstream gene analysis of the epithelial fathead minnow (FHM) cells showed upregulated expression of genes, such as FHM_NK-Lysin, FHM_Hepcidin-1, FHM_Defensin-β, encoding antimicrobial peptides, as well as of FHM_IL-1β, FHM_TNF-A, FHM_IL-11, and FHM_STAT3 genes encoding inflammation-related proteins and IL-17C receptor genes FHM_IL-17RA, and FHM_IL-17RE at 12 and 24 h after treatment with AcIL-17C. The bacterial colony counting assay showed lower colony counts of Escherichia coli grown on FHM cells transfected with AcIL-17C carrying vector compared to those grown on control FHM cells. Further, AcIL-17C had a concentration-dependent positive effect on the survival of FHM cells infected with E. coli compared to the percentage of survived control cells. There has been a lack of studies characterizing the functions of teleost IL-17C. Therefore, these findings provide important information about the teleost host defense mechanisms and insights on the IL-17C-mediated antibacterial immunity.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2021; 121:104070.

Abstract
Interleukin-17 (IL-17) is a cytokine secreted by a variety of immune cells that plays an important role in host defense against pathogens. IL-17 usually activates downstream immune signaling pathway by binding to heterodimeric or homodimeric complex formed by IL-17 receptors (IL-17R). Describing the characteristics, tissue distribution of IL-17 and IL-17 receptor family members and their expression after pathogen infection will provide a reference for host defense against disease of turbot. In this study, six IL-17 family members and nine IL-17 receptor family members were identified by analyzing the turbot (Scophthalmus maximus) genome. Different from other vertebrates, most members of the IL-17 receptor family own two copies. Protein structure analysis showed that the six IL-17 family members contained typical "IL-17" domains, and the nine IL-17 receptor family members contained typical "SEFIR domain" or "IL17_R_N domain". Syntenic analysis revealed that all IL-17s and IL-17Rs were chromosomally conserved compared with other fish. The phylogenetic analysis further confirmed the evolutionary conservatism of different copies of IL-17C and IL-17Rs. Tissue distribution results showed that IL-17 and IL-17R genes were highly expressed in immune-related tissues. The expression of IL-17C and its receptor in the mucosal immune tissues after infection with V. anguillarum were analyzed subsequently, which were significantly increased in the skin. The results are consistent with previous studies showing that IL-17 and IL-17 receptor play an important role in promoting innate immune response.

Abstract
The interleukin-17 (IL-17) family consists of proinflammatory cytokines conserved during evolution. A comparative genomics approach was applied to examine IL-17 throughout evolution from poriferans to higher vertebrates. Cnidaria was highlighted as the most ancient diverged phylum, and several evolutionary patterns were revealed. Large expansions of the IL-17 repertoire were observed in marine molluscs and echinoderm species. We further studied this expansion in filter-fed Mytilus galloprovincialis, which is a bivalve with a highly effective innate immune system supported by a variable pangenome. We recovered 379 unique IL-17 sequences and 96 receptors from individual genomes that were classified into 23 and 6 isoforms after phylogenetic analyses. Mussel IL-17 isoforms were conserved among individuals and shared between closely related Mytilidae species. Certain isoforms were specifically implicated in the response to a waterborne infection with Vibrio splendidus in mussel gills. The involvement of IL-17 in mucosal immune responses could be conserved in higher vertebrates from these ancestral lineages.

Abstract
In the intestine, the host must be able to control the gut microbiota and efficiently absorb transiently supplied metabolites, at the risk of enormous infection. In mammals, the inflammatory cytokine interleukin (IL)-17A/F is one of the key mediators in the intestinal immune system. However, many functions of IL-17 in vertebrate intestines remain unclarified. In this study, we established a gene-knockout (KO) model of IL-17 receptor A1 (IL-17RA1, an IL-17A/F receptor) in Japanese medaka (Oryzias latipes) using genome editing technique, and the phenotypes were compared to wild type (WT) based on transcriptome analyses. Upon hatching, homozygous IL-17RA1-KO medaka mutants showed no significant morphological abnormality. However, after 4 months, significant weight decreases and reduced survival rates were observed in IL-17RA1-KO medaka. Comparison of gene-expression patterns in WT and IL-17RA1-KO medaka revealed that various metabolism- and immune-related genes were significantly down-regulated in IL-17RA1-KO medaka intestine, particularly genes related to mevalonate metabolism (mvda, acat2, hmgcs1, and hmgcra) and genes related to IL-17 signaling (such as il17c, il17a/f1, and rorc) were found to be decreased. Conversely, expression of genes related to cardiovascular system development, including fli1a, sox7, and notch1b in the anterior intestine, and that of genes related to oxidation-reduction processes including ugp2a, aoc1, and nos1 in posterior intestine was up-regulated in IL-17RA1-KO medaka. These findings show that IL-17RA regulated immune- and various metabolism-related genes in the intestine for maintaining the health of Japanese medaka.

Abstract
Antimicrobial peptides (AMP) comprise a wide range of small molecules with direct antibacterial activity and immunostimulatory role and are proposed as promising substitutes of the antibiotics. Additionally, they also exert a role against other pathogens such as viruses and fungi less evaluated. NK-lysin, a human granulysin orthologue, possess a double function, taking part in the innate immunity as AMP and also as direct effector in the cell-mediated cytotoxic (CMC) response. This molecule is suggested as a pivotal molecule involved in the defence upon nervous necrosis virus (NNV), an epizootic virus provoking serious problems in welfare and health status in Asian and Mediterranean fish destined to human consumption. Having proved that NK-lysin derived peptides (NKLPs) have a direct antiviral activity against NNV in vitro, we aimed to evaluate their potential use as a prophylactic treatment for European sea bass (Dicentrarchus labrax), one of the most susceptible cultured-fish species. Thus, intramuscular injection of synthetic NKLPs resulted in a very low transcriptional response of some innate and adaptive immune markers. However, the injection of NKLPs ameliorated disease signs and increased fish survival upon challenge with pathogenic NNV. Although NKLPs showed promising results in treatments against NNV, more efforts are needed to understand their mechanisms of action and their applicability to the aquaculture industry.

Abstract
For the activation of T cells, it is necessary the specific recognition of the peptide by the T cell receptors (TCR) in the surface of antigen-presenting cells (APCs) and additional signals delivered by costimulatory receptors. In fish, knowledge about the presence of these costimulatory signals is limited and functional evidence almost absent. Thus, in this study, we have identified the stimulatory CD28 and the inhibitory cytotoxic T-lymphocyte-associated protein 4 (CTLA4) coreceptors in the European sea bass (Dicentrarchus labrax), and evaluated their transcription. In parallel, the transcription encoding for the T cell markers CD8α and CD4 was also evaluated. Both coreceptors showed the canonical architecture including a signal peptide, an immunoglobulin domain, a transmembrane region and a cytosolic tail. Protein predictions and phylogenetic tree identify them as true mammalian orthologues of CD28 and CTLA4. We found these genes constitutively expressed in all studied organs of European sea bass with high expression in lymphoid organs (thymus, spleen and head-kidney) and liver. The molecular expression pattern of these genes was up-regulated in head-kidney leucocytes stimulated with T mitogens as concanavalin A and phytohemagglutinin (PHA), but not with the B cell mitogen lipopolysaccharide (LPS). Fish challenged with nodavirus (NNV) evidenced a differential and opposing regulation of the cd28 and ctla4 transcription levels in the brain, the target organ for viral replication, and head-kidney. While cd28 transcription tends to decrease over the infection time in both organs the expression of the ctla4 gene tends to increase. Interestingly, the coreceptor expression is highly and significantly correlated to the transcription of the T cell markers. Our results highlight the important role of CD28 and CTLA4 as costimulatory receptors of T cells in European sea bass but further studies are deserved.
