Abstract
Based on previous evidence demonstrating the efficacy of inactivated mycobacteria for the control of fish mycobacteriosis, we explored the protective efficacy of two inactivated Mycobacterium bovis administered via parenteral and mucosal routes against Mycobacterium marinum infection mimicking natural conditions in the zebrafish model of tuberculosis. Although we did not observe a clear effect of any of the immunostimulants on mycobacterial burden, the results showed a significant increase in TLR2 and TLR4 gene expression levels in fishes parenterally immunized with inactivated Bacillus Calmette-Guérin (BCG). Our findings demonstrated that the TLR2 and the TLR4 signaling pathways are involved in the immune response elicited by inactivated mycobacteria in the zebrafish model of tuberculosis and support the use of inactivated mycobacteria in vaccine formulations for the control of mycobacteriosis.

Abstract
Mycobacteriosis caused by Mycobacterium spp. causes economic damages to the world aquaculture industry. In mammals, mycolic acids contained in the cell wall of Mycobacterium spp. are presented by CD1b molecule as lipid antigens and induce cell-mediated immunity (CMI). Here, we investigated CMI responses against the mycolic acids of Mycobacterioides salmoniphilum in a CD1-lacking teleost fish, rainbow trout. After stimulation of trout leukocytes with mycolic acids, the number and percentage of CD8α+ T cells increased. Fish immunized with mycolic acids showed an up-regulation of IFN-γ. Further, in vitro re-stimulation of leukocytes derived from immunized fish resulted in proliferation of CD8α+ cells. These data suggest that mycolic acids are recognized as lipid antigens resulting in an activation of rainbow trout CD8α+ cells and up-regulation of the Th1 cytokine IFN-γ. The mycolic acids are promising candidates for vaccines to activate CD8α+ T cells against fish mycobacteriosis.

Abstract
Administration of β-glucans through various routes, including immersion, dietary inclusion, or injection, have been found to stimulate various facets of immune responses, such as resistance to infections and resistance to environmental stress. β-Glucans used as an immunomodulatory food supplement have been found beneficial in eliciting immunity in commercial aquaculture. Despite extensive research involving more than 3000 published studies, knowledge of the receptors involved in recognition of β-glucans, their downstream signaling, and overall mechanisms of action is still lacking. The aim of this review is to summarize and discuss what is currently known about of the use of β-glucans in fish.

Mycobacteriosis and Infections with Non-tuberculous Mycobacteria in Aquatic Organisms: A Review. Microorganisms 2020; 8:microorganisms8091368.

Abstract
The Mycobacteriaceae constitute a family of varied Gram-positive organisms that include a large number of pathogenic bacteria. Among these, non-tuberculous mycobacteria are endemic worldwide and have been associated with infections in a large number of organisms, including humans and other mammals and reptiles, as well as fish. In this review, we summarize the most recent findings regarding this group of pathogens in fish. There, four species are most commonly associated with disease outbreaks: Mycobacterium marinum, the most common of these fish mycobacterial pathogens, Mycobacterium fortuitum, Mycobacterium gordonae, and Mycobacterium chelonae. These bacteria have a broad host range: they are zoonotic, and infections have been reported in a large number of fish species. The main route of entry of the bacterium into the fish is through the gastrointestinal route, and the disease is associated with ulcerative dermatitis as well as organomegaly and the development of granulomatous lesions in the internal organs. Mycobacteriaceae are slow-growing and fastidious and isolation is difficult and time consuming and diagnostic is mostly performed using serological and molecular tools. Control of the disease is also difficult: there is currently no effective vaccine and infections react poorly to antibiotherapy. For this reason, more research is needed on the subject of these vexing pathogens.

Abstract
Tuberculosis is a chronic infection by Mycobacterium tuberculosis that results in over 1.5 million deaths worldwide each year. Currently, there is only one vaccine against tuberculosis, the Bacillus Calmette–Guérin (BCG) vaccine. Despite widespread vaccination programmes, over 10 million new M. tuberculosis infections are diagnosed yearly, with almost half a million cases caused by antibiotic-resistant strains. Novel vaccination strategies concentrate mainly on replacing BCG or boosting its efficacy and depend on animal models that accurately recapitulate the human disease. However, efforts to produce new vaccines against an M. tuberculosis infection have encountered several challenges, including the complexity of M. tuberculosis pathogenesis and limited knowledge of the protective immune responses. The preclinical evaluation of novel tuberculosis vaccine candidates is also hampered by the lack of an appropriate animal model that could accurately predict the protective effect of vaccines in humans. Here, we review the role of zebrafish (Danio rerio) and other fish models in the development of novel vaccines against tuberculosis and discuss how these models complement the more traditional mammalian models of tuberculosis. Summary: In this Review, we discuss how zebrafish (Danio rerio) and other fish models can complement the more traditional mammalian models in the development of novel vaccines against tuberculosis.

Abstract
Antimicrobial resistance (AMR) is a significant problem in health care, animal health, and food safety. To limit AMR, there is a need for alternatives to antibiotics to enhance disease resistance and support judicious antibiotic usage in animals and humans. Immunomodulation is a promising strategy to enhance disease resistance without antibiotics in food animals. One rapidly evolving field of immunomodulation is innate memory in which innate immune cells undergo epigenetic changes of chromatin remodeling and metabolic reprogramming upon a priming event that results in either enhanced or suppressed responsiveness to secondary stimuli (training or tolerance, respectively). Exposure to live agents such as bacille Calmette-Guerin (BCG) or microbe-derived products such as LPS or yeast cell wall ß-glucans can reprogram or "train" the innate immune system. Over the last decade, significant advancements increased our understanding of innate training in humans and rodent models, and strategies are being developed to specifically target or regulate innate memory. In veterinary species, the concept of enhancing the innate immune system is not new; however, there are few available studies which have purposefully investigated innate training as it has been defined in human literature. The development of targeted approaches to engage innate training in food animals, with the practical goal of enhancing the capacity to limit disease without the use of antibiotics, is an area which deserves attention. In this review, we provide an overview of innate immunomodulation and memory, and the mechanisms which regulate this long-term functional reprogramming in other animals (e.g., humans, rodents). We focus on studies describing innate training, or similar phenomenon (often referred to as heterologous or non-specific protection), in cattle, sheep, goats, swine, poultry, and fish species; and discuss the potential benefits and shortcomings of engaging innate training for enhancing disease resistance.

Abstract
Aquaculture is an important industry in Japan for the sustainable production of fish. It contributes to the diversity of Japanese traditional food culture, which uses fish such as "sushi" and "sashimi". In the recent aquaculture setting in Japan, infectious diseases have been an unavoidable problem and have caused serious economic losses. Therefore, there is an urgent need to overcome the disease problem to increase the productivity of aquaculture. Although our country has developed various effective vaccines against fish pathogens, which have contributed to disease prevention on fish farms, infectious diseases that cannot be controlled by conventional inactivated vaccines are still a problem. Therefore, other approaches to developing effective vaccines other than inactivated vaccines are required. This review introduces the vaccine used in Japan within the context of the current status of finfish aquacultural production and disease problems. This review also summarizes the current research into vaccine development and discusses the future perspectives of fish vaccines, focusing on the problems associated with vaccine promotion in Japan.

Abstract
Intracellular bacterial infections affect all vertebrates. Cultured fish are particularly vulnerable because no effective protection measures have been established since such infections emerged approximately 50 years ago. As in other vertebrates, the induction of cell-mediated immunity (CMI) plays an important role in protecting fish against infection. However, details of the mechanism of CMI induction in fish have not been clarified. In the present study, we focused on the production of interleukin 12 (IL-12), an important factor in CMI induction in fish. Using several different approaches, we investigated IL-12 regulation in amberjack (Seriola dumerili), the species most vulnerable to intracellular bacterial disease. The results of promoter assays and transcription factor gene expression analyses showed that the expression of interferon regulatory factor-1 (IRF-1) and activator protein-1 (AP-1) is necessary for IL-12 production. Phagocytosis of living cells (LCs) of Nocardia seriolae bacteria induced IL-12 production in neutrophils, accompanied by IRF-1 and AP-1 gene expression. Bacteria in which the exported repetitive protein (Erp)-like gene was deleted (Δerp-L) could not establish intracellular parasitism or induce IRF-1 and AP-1 expression or IL-12 production, despite being phagocytosed by neutrophils. These data suggest that IL-12 production is regulated by (i) two transcription factors, IRF-1 and AP-1, (ii) phagocytosis of LCs by neutrophils, and (iii) one or more cell components of LCs. Our results enhance the understanding of the immune response to intracellular bacterial infections in vertebrates and could facilitate the discovery of new agents to prevent intracellular bacterial disease.

Abstract
Trained immunity is a form of innate immune memory best described in mice and humans. Clear evidence of the evolutionary conservation of trained immunity in teleost fish is lacking. Given the evolutionary position of teleosts as early vertebrates with a fully developed immune system, we hypothesize that teleost myeloid cells show features of trained immunity common to those observed in mammalian macrophages. These would at least include the ability of fish macrophages to mount heightened responses to a secondary stimulus in a nonspecific manner. We established an in vitro model to study trained immunity in fish by adapting a well-described culture system of head kidney-derived macrophages of common carp. A soluble NOD-specific ligand and a soluble β-glucan were used to train carp macrophages, after which cells were rested for 6 d prior to exposure to a secondary stimulus. Unstimulated trained macrophages displayed evidence of metabolic reprogramming as well as heightened phagocytosis and increased expression of the inflammatory cytokines il6 and tnf-α. Stimulated trained macrophages showed heightened production of reactive oxygen and nitrogen species as compared with the corresponding stimulated but untrained cells. We discuss the value of our findings for future studies on trained immunity in teleost fish.

Abstract
Mycobacteriosis is a chronic progressive disease affecting teleost fishes all over the world. No vaccine is commercially available against its main etiological agent, Mycobacterium marinum. The mycobacterial gene responsible for invasion and intracellular persistence, iipA, is known to modulate M. marinum pathology. The innate and adaptive immune responses in sea bass (Dicentrarchus labrax) vaccinated with M. marinum iipA::kan mutant with (and without) the use of adjuvant, with (and without) a booster vaccination were monitored. The adjuvanted vaccine induced enhanced immune responses. TNF-α transcription levels were extremely high in spleen of the fish vaccinated with the addition of adjuvant in both fish vaccinated once and twice, followed by an IgM response highly specific for M. marinum. Also, histologically, granulomas started appearing in spleen and head-kidney tissues (but with no visible bacteria) within a month after vaccination, mainly with the adjuvanted vaccine. This was followed by reduction in pathology, as demonstrated by the lower number of granulomas (with visible bacteria), indicating that even heat-killed bacteria were able to elicit granulomatous formations. Adhesion of the internal organs and moderate pigmentation were observed in the perivisceral adipose tissue of nearly all vaccinated fish. Although the adjuvanted heat-killed avirulent iipA::kan mutant clearly induced a strong humoral and adaptive immune response, the booster treatment did not seem to have produced a significantly higher degree of protection from the disease compared to fish that received a single vaccination.

Abstract
In this study, we investigated the immune responses against Mycobacterium gordonae in ginbuna crucian carp. Cumulative mortality of ginbuna injected with 2.0 × 107 CFU of M. gordonae was 50% at 170 days post-infection. CD4-1, CD8α, T-bet and IFNγ2 gene expression levels were significantly upregulated in ginbuna injected with 1.9 × 108 CFU of M. gordonae at 21 and 28 days post-infection. The CD4-2 level did not change during the experiment. Granulomatous responses consisted of central macrophage accumulation and surrounding lymphocytes, and Ziehl-Neelsen-positive bacteria were observed in the trunk kidney of the challenged fish. Immunohistochemistry using anti-ginbuna IFNγs and anti-ginbuna CD4-1 polyclonal antibody revealed that the marginal lymphocytes were positive for CD4-1, and the IFNγ-producing cells surrounded the mycobacterial cell-laden phagocytes. These results suggest that CD4-1+ cells and IFNγ2 play important roles in the granulomatous inflammation against Mycobacterial infections in teleosts.

Abstract
No vaccine is yet commercially available against Mycobacterium marinum, the etiological agent of fish mycobacteriosis (also known as "fish tuberculosis"). The mycobacterial gene responsible for invasion and intracellular persistence, iipA, is known to moderate M. marinum pathology in Zebrafish Danio rerio. Two doses of heat-killed, wild-type, virulent M. marinum and two doses of a heat-killed, avirulent M. marinum iipA::kan mutant strain were used in parallel to vaccinate European Seabass Dicentrarchus labrax. The fish were then challenged with live, virulent M. marinum, and the pathogenesis of the infection was monitored. High specific immunoglobulin M (IgM) response and an increase in cytokine tumor necrosis factor alpha (TNF-α) messenger RNA expression levels were observed in all vaccinated fish. At 1 month postchallenge, TNF-α expression levels increased in spleen tissues of fish vaccinated with the virulent type and in those of unvaccinated fish, whereas in the head kidney, expression was up-regulated only in unvaccinated fish. The expression then decreased, and at 2 months postchallenge, expression appeared similar in all vaccination types. The highest survival rate (75%) was recorded in the group of fish that were vaccinated with a high dose of avirulent iipA::kan mutant. The iipA::kan mutant induced a strong immune response accompanied by only modest tissue disruption. Coupled with an effective program of booster treatments, the iipA::kan mutant vaccine may be developed into a powerful preventive measure against fish mycobacteriosis.

Abstract
Mycobacteriosis and nocardiosis in cultured fish caused by infections with acid-fast bacteria, are responsible for large economic losses globally. In this study, we suggest a novel adjuvant using glycolipids that activates host immune systems. The immune response to glycolipids stimulation was investigated using ginbuna crucian carp. Ginbuna vaccinated with FKC (formalin-killed cells) + glycolipids isolated from Mycobacterium sp., upregulated inflammatory- and Th1-related cytokines, and a DTH (delayed-type hypersensitivity) response was confirmed only in ginbuna vaccinated with FKC + glycolipids. These observations suggest that glycolipids activated host innate and cell-mediated immunity. Subsequently, we evaluated the adjuvant effect of glycolipids against amberjack nocardiosis. In a challenge test, a higher survival rate was observed in amberjack vaccinated with FKC + glycolipids emulsified with conventional oil adjuvant than in fish vaccinated with FKC + oil adjuvant without glycolipids. Therefore, glycolipids potentially could be used as a practical, economical and safe adjuvant for aquaculture fish.

Adjuvant effect of recombinant interleukin-12 in the Nocardiosis formalin-killed vaccine of the amberjack Seriola dumerili. FISH & SHELLFISH IMMUNOLOGY 2017; 67:263-269.

Abstract
Nocardiosis causes serious economic damage in the fish farming of Japanese yellowtail fish. Nocardia seriolae identified as pathogenic bacterium is an intracellular-pathogen. In general, induction of cell-mediated immunity (CMI) is effective in infection defense against intracellular-pathogen. However, the conventional formalin-killed N. seriolae (FKC) vaccine induces humoral immunity. Interleukin-12 (IL-12) is Th1 type heterodimeric cytokine and induces cell differentiation in mammals. Our previous study showed that recombinant amberjack IL-12 has a role in CMI induction in vitro and could be a possible CMI inducing adjuvant. However, its adjuvant effect of fish IL-12 was not studied. In the present study, six types of amberjack recombinant IL-12 (rIL-12) were mixed and injected into amberjack with FKC. Firstly, we analyzed Th1- and Th2- related gene expression and monitored Th1/Th2 status followed by investigation of antibody titer. As a result, Th1-type immunity was induced in FKC + rIL-12 vaccinated fish. Secondly, we checked Th1/Th2 status of vaccinated fish after 10 days of N. seriolae infection using the expression of related genes. High T-bet/GATA-3 ratio was observed in FKC + rIL-12 vaccinated fish, suggesting that Th1 cells possesing antigen memory were induced against N. seriolae infection. Finally, the survival rate in challenge test showed that 88% of FKC + rIL-12 vaccinated fish was survived at 34 days after N. seriolae injection whereas PBS (control) and FKC only were exterminated. These result suggest that i) rIL-12 is viable CMI inducible adjuvant and ii) production of Th1 cells having antigen memory resulting from activation of IL-12 signaling pathway is important for defense against N. seriolae infection.

Abstract
Over the past decades, it has become evident that immune-modulation of fish with β-glucans, using injection, dietary or even immersion routes of administration, has stimulating but presumed short-lived effects on both intestinal and systemic immunity and can increase protection against a subsequent pathogenic challenge. Although the exact effects can be variable depending on, among others, fish species and administration route, the immune-stimulating effects of β-glucans on the immune system of fish appear to be universal. This review provides a condensed update of the most recent literature describing the effects of β-glucans on the teleost fish immune system. We shortly discuss possible mechanisms influencing immune-stimulation by β-glucans, including microbial composition of the gut, receptor recognition and downstream signalling. Of interest, in mammalian monocytes, β-glucans are potent inducers of trained immunity. First, we screened the literature for indications of this phenomenon in fish. Criteria that we applied include indications for at least one out of three features considered characteristic of trained immunity; (i) providing protection against a secondary infection in a T- and B-lymphocyte independent manner, (ii) conferring increased resistance upon re-infection and, (iii) relying on key roles for innate immune cell types such as natural killer cells and macrophages. We conclude that several indications exist that support the notion that the innate immune system of teleost fish can be trained. Second, we screened the literature for indications of long-lived effects on innate immunity of fish after administering β-glucans, a criterion which could help to identify key roles for macrophages on resistance to infection. We discuss whether β-glucans, as well-known immune-stimulants, are able to train the immune system of fish and argue in favour of further studies designed to specifically investigate this phenomenon in fish.

Abstract
Tuberculosis (TB) is a global health emergency. Up to one-third of the world’s population is infected with Mycobacterium tuberculosis, and the pathogen continues to kill 1.5 million people annually. Currently, the means for preventing, diagnosing, and treating TB are unsatisfactory. One of the main reasons for the poor progress in TB research has been a lack of good animal models to study the latency, dormancy, and reactivation of the disease. Although sophisticated in vitro and in silico methods suitable for TB research are constantly being developed, they cannot reproduce the complete vertebrate immune system and its interplay with pathogens and vaccines. However, the zebrafish has recently emerged as a useful alternative to more traditional models, such as mice, rabbits, guinea pigs, and non-human primates, for studying the complex pathophysiology of a mycobacterial infection. The model is based on the similarity between Mycobacterium marinum – a natural fish pathogen – and M. tuberculosis. In both zebrafish larvae and adult fish, an infection with M. marinum leads to the formation of macrophage aggregates and granulomas, which resemble the M. tuberculosis infections in humans. In this review, we will summarize the current status of the zebrafish model in TB research and highlight the advantages of using zebrafish to dissect mycobacterial virulence strategies as well as the host immune responses elicited against them. In addition, we will discuss the possibilities of using the adult zebrafish model for studying latency, dormancy, and reactivation in a mycobacterial infection.

Abstract
Despite the widespread use of the current Bacillus Calmette-Guérin (BCG) vaccine, tuberculosis is still a major cause of morbidity and mortality worldwide. Vaccination with BCG does not prevent a Mycobacterium tuberculosis infection, nor does it inhibit the reactivation of latent tuberculosis. Here, we show that adult zebrafish are modestly and variably protected from a mycobacterial infection by BCG vaccination. An intraperitoneal (i.p.) BCG vaccination was associated with enhanced survival upon a high-dose (20,000 bacteria) Mycobacterium marinum infection. In addition, BCG-vaccinated fish were more able to restrict a low-dose (30 bacteria) intraperitoneal infection with M. marinum, as indicated by lower bacterial loads at six weeks post infection (wpi). However, the vaccination could not completely prevent an infection. A qRT-PCR analysis comparing BCG-vaccinated and unvaccinated fish upon a mycobacterial infection indicated that the induction of Tumor necrosis factor (TNF) was more modest in vaccinated fish. The partial protection gained by BCG could be boosted by a DNA vaccine combining Ag85B, ESAT6 and a resuscitation-related gene RpfE, suggesting that this combination of antigens could be useful for a future BCG booster vaccine. We conclude that zebrafish is a useful early-phase preclinical model for studying subunit vaccines designed for boosting the effects of BCG.

Abstract
Edwardsiella tarda is an intracellular pathogen that causes edwardsiellosis in fish. Although vaccine trials with formalin-killed cells (FKC) have been reported, the vaccinations failed in protect against E. tarda infection. On the other hand, a live attenuated vaccine strategy is effective against edwardsiellosis; however, the mechanism underlying its effectiveness in fish is unclear. In the present study, we compared the adaptive immune responses in fish vaccinated with FKCs and live attenuated vaccines to elucidate the induction of adaptive immune responses following vaccination. After challenge with E. tarda, live cell (LC)-vaccinated fish showed high survival rates, high IFN-g and T-bet gene expression levels, and increased cytotoxic T lymphocytes (CTLs). In contrast, all FKC-vaccinated fish died following E. tarda infection. In addition, FKC vaccination induced high IL-4/13A and IL-10 expression levels and increased antibody titers, whereas Th1-like responses were suppressed. These results indicate that LC vaccination contributes to protection against E. tarda infection by inducing cell-mediated immunity (CMI). Thus our study findings could contribute to the development a vaccine that induces CMI against edwardsiellosis.

Abstract
Ayu Plecoglossus altivelis altivelis are one of the most economically important fish for freshwater aquaculture in Japan. We conducted expressed sequence tag analyses of three leukocyte subpopulations, thrombocytes, neutrophils, and B lymphocytes in ayu using a next generation sequencer. The sequencing and de novo assembly yielded 22,494, 22,733, and 16,505 contigs from the thrombocyte, neutrophil, and B lymphocyte cDNA libraries, respectively. Pathways involving endocytosis, phagosomes, and lysosomes, were found in all three cDNA libraries using pathway analysis. The thrombocyte cDNA library contained 2894 unique sequences, including CXC chemokine receptor 4 and MHC class II. Cytokine and cytokine receptor genes such as interleukin (IL)-1β, IL-8, IL-1 receptor (IL-1R), IL-8RA, and IL-8RB were found among the 3056 unique sequences of the neutrophil cDNA library. Typical B lymphocyte related genes such as B cell linker protein, immunoglobulin (Ig) M, IgD and transforming growth factor β were found in the 1590 unique sequences of the B lymphocyte cDNA library. In summary, a large number of immune-related genes were identified from the three leukocyte cDNA libraries. Our results represent a valuable sequence resource for understanding the immune system function in ayu.

Abstract
The uses of single walled carbon nanotubes (SWCNTs) as carriers for DNA delivery have received considerable attention in cell studies. DNA vaccination of fish has been shown to elicit durable transgene expression, but no reports exist on intramuscular administration of SWCNTs-DNA vaccine electrostatic complexes which prepared through non-covalent conjugation. In this study, we injected grass carp intramuscularly with a plasmid vector containing a major capsid protein gene (vp7) of grass carp reovirus as a) naked pcDNA-vp7, b) SWCNTs-pcDNA-vp7, c) empty plasmid vector, or phosphate buffered saline. After intramuscular administration, the ability of the different immune treatments to induce transgene expression was analyzed. The results indicated that higher levels of transcription and expression of the vp7 gene could be detected in muscle tissues of grass carp 28 days intramuscular injection in SWCNTs-pcDNA-vp7 treatment groups compare with naked pcDNA-vp7 treatment groups. Moreover, the serum respiratory burst activity, complement activity, lysozyme activity, superoxide dismutase activity, immune-related genes, antibody levels and relative percentage survival were significantly enhanced in fish immunized with SWCNTs-pcDNA-vp7 vaccine. The data in this study suggested that SWCNTs were promising carriers for plasmid DNA vaccine and might be used to vaccinate fish by intramuscular approach.

Abstract
Gene expression profiling was performed in Japanese flounder Paralichthys olivaceus fed diets supplemented with fish oil (FO), linseed oil (LO), or olive oil (OO) for 6 weeks. The LO and OO groups showed significantly retarded growth, lower feed intake, lower protein efficiency ratio, and lower hepatosomatic index (P < 0.05). Liver fatty acid composition reflected the dietary fatty acid composition. Microarray analysis revealed that dietary n - 3 highly unsaturated fatty acid (HUFA) deficiency affected 169 transcripts. In the LO group, 57 genes were up-regulated and 38 genes were down-regulated, whereas in the OO group nine genes were up-regulated and 87 genes were down-regulated. Analysis of the functional annotations suggested that dietary n - 3 HUFA affected genes involved in signal transduction (23.2 %), cellular processes (21.1 %), metabolism (including glucose, lipid, and nucleobase; 15.5 %), transport (11.3 %), regulation of transcription (10.5 %), and immune response (4.2 %). Several genes encoding serine/threonine kinases such as protein kinase C and calmodulin-dependent kinase and nuclear hormone receptors such as vitamin D receptor, retinoic acid receptor, and receptors for cytokines (bone morphogenic protein and transforming growth factor β) were affected. Among 169 transcripts, 22 genes were affected in both LO and OO groups. The present study identified several genes involved in n - 3 HUFA deficiency-sensitive pathways, which will be useful for selective breeding of flounder strains able to adapt to n - 3 HUFA deficiency.

Abstract
CD4 and CD8 molecules are co-receptors of T cell receptors which interact specifically with MHC class II and I, respectively, during antigen presentation. Here we investigated CD4 and CD8 expression patterns in a fish, Japanese flounder, Paralichthys olivaceus in response to infection and tuberculin injection. The CD4-1 mRNA level was gradually and weakly increased in trunk kidney after infection with Streptococcus iniae, Edwardsiella tarda and viral hemorrhagic septicemia virus (VHSV), while the CD4-2 mRNA level was dramatically increased after E. tarda and VHSV infection, but not increased after S. iniae infection. CD4-2 mRNA but not CD4-1mRNA increased in the kidney during tuberculin response which is mediated by memory Th1 cells. The patterns for the change of mRNA level in CD8α and CD8β were similar to those of the CD4-2 during the infections and tuberculin response. Fluorescent in situ hybridization detected CD4-1 mRNAs on melano-macrophage centers and CD4-2 mRNAs at some cell clusters located near the melano-macrophage centers. CD8α and CD8β mRNAs were detected at the same cell clusters in the spleen and head kidney. These results suggest that CD4-1 and CD4-2 are expressed in different cells and that CD4-2-positive cells, rather than CD4-1-positive cells, have a main role in Th1-related immune responses collaborating with CD8α- and CD8β-positive cells in Japanese flounder.

Abstract
Nocardiosis caused by Nocardia seriolae has been causing severe loss of fish production, so that an effective vaccine is urgently needed. Mycobacterium bovis BCG (BCG) is a live attenuated vaccine for tuberculosis, which is effective against various infectious diseases including nocardiosis in mammals. In this study, the protective efficacy of BCG against N. seriolae was evaluated in Japanese flounder Paralichthys olivaceus and antigen-specific immune responses induced in BCG vaccinated fish were investigated. Cumulative mortality of BCG-vaccinated fish was 21.4% whereas that of PBS-injected fish was 56.7% in N. seriolae challenge. However, gene expression level of IFN-γ was only slightly up-regulated in BCG-vaccinated fish after injection of N. seriolae antigen. In order to reveal non-specific immune responses induced by BCG vaccination, transcriptome of the kidney after BCG vaccination was investigated using oligo DNA microarray. Gene expression levels of antimicrobial peptides such as C-type and G-type lysozyme were significantly up-regulated after BCG vaccination. Consistently, BCG vaccination appeared to increase the bacteriolysis activity of the serum against Micrococcus luteus and N. seriolae. These results suggest that BCG-vaccinated Japanese flounder fight N. seriolae infection mainly by non-specific immune responses such as by the production of bacteriolytic lysozymes.

A novel immune-related gene, microtubule aggregate protein homologue, is up-regulated during IFN-γ-related immune responses in Japanese flounder, Paralichthys olivaceus. DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2012; 36:349-358.

Abstract
Delayed-type hypersensitivity (DTH) response mediated by antigen-specific Th1 cells is used as a test to detect exposure to tuberculosis in humans. Japanese flounder (Paralichthys olivaceus) microtubule aggregate protein homologue (PoMTAP) was identified as a gene strongly induced during fish DTH response. In this study, PoMTAP gene was cloned and its expression profile was analyzed. The PoMTAP gene has a transcriptional regulatory region that includes two interferon-stimulated response elements and two IFN-γ activated sites. Expressions of PoMTAP and IFN-γ genes were up-regulated at the same time points during the DTH response, Edwardsiella tarda infection and VHSV infection. Furthermore, PoMTAP gene expressing cells also expressed CD3ε, confirming that PoMTAP is expressed by T lymphocytes. These results suggest that PoMTAP is a novel immune-related gene expressed by T lymphocytes that is preferentially induced by IFN-γ and has a role in Th1-mediated immune responses in Japanese flounder.

Abstract
Mycobacteriosis, caused by the intracellular parasitism Mycobacterium sp., causes economic damages to aquaculture production in Japan, particularly in seriola fish production. Antibiotics are not effective against Mycobacterium sp. and so a potent vaccine is needed. We previously reported that BCG vaccine (Mycobacterium bovis BCG) induces adaptive immunity against Mycobacterium sp. in Japanese flounder, Paralichthys olivaceus. In a phylogenetic tree, the genes for a major antigen, the Ag85 complex, in Mycobacterium sp. TUMSAT-Msp001 are closely related to homologues in Mycobacterium ulcerans. M. bovis BCG was detected until 7 days post-injection at the injection site (muscle) and 28 days post-vaccination in spleen. Cumulative mortality of amberjack, Seriola dumerili vaccinated intramuscularly (i.m.) and intraperitoneally (i.p.) with M. bovis BCG was 32.3% and 59.5% respectively, at 24 days post-infection of Mycobacterium sp., compared to 97.8% in PBS-injected fish. The bacterial counts of Mycobacterium sp. in spleen of both i.m.-and i.p.-vaccinated fish (6.2 x 10³ and 1.3 x 10⁴ CFU/mg tissue, respectively) at 20 days post-infection were significantly lower (P < 0.01) than those of PBS-injected fish (8.0 x 10⁶ CFU/mg). Furthermore, Immersion challenge with Mycobacterium sp. TUMSAT Msp-001 showed 50% RPS value in BCG i.m.-vaccinated fish at the end of the experiment. These results support our previous study using Japanese flounder and suggest that BCG vaccine is also effective against Mycobacterium sp. infection in amberjack.

Abstract
Flatfishes are a group of teleosts of high commercial and environmental interest, whose biology is still poorly understood. The recent rapid development of different 'omic' technologies is, however, enhancing the knowledge of the complex genetic control underlying different physiological processes of flatfishes. This review describes the different functional genomic approaches and resources currently available for flatfish research and summarizes different areas where microarray-based gene expression analysis has been applied. The increase in genome sequencing data has also allowed the construction of genetic linkage maps in different flatfish species; these maps are invaluable for investigating genome organization and identifying genetic traits of commercial interest. Despite the significant progress in this field, the genomic resources currently available for flatfish are still scarce. Further intensive research should be carried out to develop larger genomic sequence databases, high-density microarrays and, more detailed, complete linkage maps, using second-generation sequencing platforms. These tools will be crucial for further expanding the knowledge of flatfish physiology, and it is predicted that they will have important implications for wild fish population management, improved fish welfare and increased productivity in aquaculture.
